+ Migrating from Vim
+Helix's editing model is strongly inspired from Vim and Kakoune, and a notable
+difference from Vim (and the most striking similarity to Kakoune) is that Helix
+follows the selection → action model. This means that the whatever you are
+going to act on (a word, a paragraph, a line, etc) is selected first and the
+action itself (delete, change, yank, etc) comes second. A cursor is simply a
+single width selection.
See also Kakoune's Migrating from Vim and Helix's Migrating from Vim.

+ Adding languages
+Language configuration
+To add a new language, you need to add a [[language]] entry to the
+languages.toml (see the language configuration section).
When adding a new language or Language Server configuration for an existing
+language, run cargo xtask docgen to add the new configuration to the
+Language Support docs before creating a pull request.
+When adding a Language Server configuration, be sure to update the
+Language Server Wiki with installation notes.
Grammar configuration
+If a tree-sitter grammar is available for the language, add a new [[grammar]]
+entry to languages.toml.
You may use the source.path key rather than source.git with an absolute path
+to a locally available grammar for testing, but switch to source.git before
+submitting a pull request.
Queries
+For a language to have syntax-highlighting and indentation among
+other things, you have to add queries. Add a directory for your
+language with the path runtime/queries/<name>/. The tree-sitter
+website
+gives more info on how to write queries.
++NOTE: When evaluating queries, the first matching query takes +precedence, which is different from other editors like Neovim where +the last matching query supersedes the ones before it. See +this issue for an example.
+
Common Issues
+-
+
-
+
If you get errors when running after switching branches, you may have to update the tree-sitter grammars. Run
+hx --grammar fetchto fetch the grammars andhx --grammar buildto build any out-of-date grammars.
+ -
+
If a parser is segfaulting or you want to remove the parser, make sure to remove the compiled parser in
+runtime/grammar/<name>.so

+
+ Adding Indent Queries
+Helix uses tree-sitter to correctly indent new lines. This requires
+a tree-sitter grammar and an indent.scm query file placed in
+runtime/queries/{language}/indents.scm. The indentation for a line
+is calculated by traversing the syntax tree from the lowest node at the
+beginning of the new line. Each of these nodes contributes to the total
+indent when it is captured by the query (in what way depends on the name
+of the capture).
Note that it matters where these added indents begin. For example, +multiple indent level increases that start on the same line only increase +the total indent level by 1.
+Scopes
+Added indents don't always apply to the whole node. For example, in most +cases when a node should be indented, we actually only want everything +except for its first line to be indented. For this, there are several +scopes (more scopes may be added in the future if required):
+-
+
-
+
+all: +This scope applies to the whole captured node. This is only different from +tailwhen the captured node is the first node on its line.
+ -
+
+tail: +This scope applies to everything except for the first line of the +captured node.
+
Every capture type has a default scope which should do the right thing
+in most situations. When a different scope is required, this can be
+changed by using a #set! declaration anywhere in the pattern:
(assignment_expression
+ right: (_) @indent
+ (#set! "scope" "all"))
+Capture Types
+-
+
-
+
+@indent(default scopetail): +Increase the indent level by 1. Multiple occurrences in the same line +don't stack. If there is at least one@indentand one@outdent+capture on the same line, the indent level isn't changed at all.
+ -
+
+@outdent(default scopeall): +Decrease the indent level by 1. The same rules as for@indentapply.
+ -
+
+@extend: +Extend the range of this node to the end of the line and to lines that +are indented more than the line that this node starts on. This is useful +for languages like Python, where for the purpose of indentation some nodes +(like functions or classes) should also contain indented lines that follow them.
+ -
+
+@extend.prevent-once: +Prevents the first extension of an ancestor of this node. For example, in Python +a return expression always ends the block that it is in. Note that this only stops the +extension of the next@extendcapture. If multiple ancestors are captured, +only the extension of the innermost one is prevented. All other ancestors are unaffected +(regardless of whether the innermost ancestor would actually have been extended).
+
Predicates
+In some cases, an S-expression cannot express exactly what pattern should be matched.
+For that, tree-sitter allows for predicates to appear anywhere within a pattern,
+similar to how #set! declarations work:
(some_kind
+ (child_kind) @indent
+ (#predicate? arg1 arg2 ...)
+)
+The number of arguments depends on the predicate that's used.
+Each argument is either a capture (@name) or a string ("some string").
+The following predicates are supported by tree-sitter:
-
+
-
+
+#eq?/#not-eq?: +The first argument (a capture) must/must not be equal to the second argument +(a capture or a string).
+ -
+
+#match?/#not-match?: +The first argument (a capture) must/must not match the regex given in the +second argument (a string).
+
Additionally, we support some custom predicates for indent queries:
+-
+
-
+
+#not-kind-eq?: +The kind of the first argument (a capture) must not be equal to the second +argument (a string).
+ -
+
+#same-line?/#not-same-line?: +The captures given by the 2 arguments must/must not start on the same line.

+ Adding Textobject Queries
+Textobjects that are language specific (like functions, classes, etc)
+require an accompanying tree-sitter grammar and a textobjects.scm query file
+to work properly. Tree-sitter allows us to query the source code syntax tree
+and capture specific parts of it. The queries are written in a lisp dialect.
+More information on how to write queries can be found in the official tree-sitter
+documentation.
Query files should be placed in runtime/queries/{language}/textobjects.scm
+when contributing. Note that to test the query files locally you should put
+them under your local runtime directory (~/.config/helix/runtime on Linux
+for example).
The following captures are recognized:
+| Capture Name |
|---|
function.inside |
function.around |
class.inside |
class.around |
test.inside |
test.around |
parameter.inside |
comment.inside |
comment.around |
Example query files can be found in the helix GitHub repository.
+Queries for Textobject Based Navigation
+Tree-sitter based navigation is done using captures in the +following order:
+-
+
object.movement
+object.around
+object.inside
+
For example if a function.around capture has been already defined for a language
+in it's textobjects.scm file, function navigation should also work automatically.
+function.movement should be defined only if the node captured by function.around
+doesn't make sense in a navigation context.

+ Installation
+We provide pre-built binaries on the GitHub Releases page.
+
OSX
+Helix is available in homebrew-core:
+brew install helix
+Linux
+NixOS
+A flake containing the package is available in
+the project root. The flake can also be used to spin up a reproducible development
+shell for working on Helix with nix develop.
Flake outputs are cached for each push to master using +Cachix. The flake is configured to +automatically make use of this cache assuming the user accepts +the new settings on first use.
+If you are using a version of Nix without flakes enabled you can
+install Cachix cli; cachix use helix will
+configure Nix to use cached outputs when possible.
Arch Linux
+Releases are available in the community repository.
A helix-git package is also available on the AUR, which builds the master branch.
+Fedora Linux
+You can install the COPR package for Helix via
+sudo dnf copr enable varlad/helix
+sudo dnf install helix
+Void Linux
+sudo xbps-install helix
+Windows
+Helix can be installed using Scoop, Chocolatey +or MSYS2.
+Scoop:
+scoop install helix
+Chocolatey:
+choco install helix
+MSYS2:
+pacman -S mingw-w64-i686-helix
+or
+pacman -S mingw-w64-x86_64-helix
+or
+pacman -S mingw-w64-ucrt-x86_64-helix
+Build from source
+git clone https://github.com/helix-editor/helix
+cd helix
+cargo install --path helix-term
+This will install the hx binary to $HOME/.cargo/bin and build tree-sitter grammars in ./runtime/grammars.
Helix also needs its runtime files so make sure to copy/symlink the runtime/ directory into the
+config directory (for example ~/.config/helix/runtime on Linux/macOS). This location can be overridden
+via the HELIX_RUNTIME environment variable.
| OS | Command |
|---|---|
| Windows (Cmd) | xcopy /e /i runtime %AppData%\helix\runtime |
| Windows (PowerShell) | xcopy /e /i runtime $Env:AppData\helix\runtime |
| Linux / macOS | ln -s $PWD/runtime ~/.config/helix/runtime |
Starting with Windows Vista you can also create symbolic links on Windows. Note that this requires +elevated privileges - i.e. PowerShell or Cmd must be run as administrator.
+PowerShell:
+New-Item -ItemType SymbolicLink -Target "runtime" -Path "$Env:AppData\helix\runtime"
+Cmd:
+cd %appdata%\helix
+mklink /D runtime "<helix-repo>\runtime"
+The runtime location can be overridden via the HELIX_RUNTIME environment variable.
++NOTE: if
+HELIX_RUNTIMEis set prior to callingcargo install --path helix-term, +tree-sitter grammars will be built in$HELIX_RUNTIME/grammars.
If you plan on keeping the repo locally, an alternative to copying/symlinking
+runtime files is to set HELIX_RUNTIME=/path/to/helix/runtime
+(HELIX_RUNTIME=$PWD/runtime if you're in the helix repo directory).
To use Helix in desktop environments that supports XDG desktop menu, including Gnome and KDE, copy the provided .desktop file to the correct folder:
cp contrib/Helix.desktop ~/.local/share/applications
+To use another terminal than the default, you will need to modify the .desktop file. For example, to use kitty:
sed -i "s|Exec=hx %F|Exec=kitty hx %F|g" ~/.local/share/applications/Helix.desktop
+sed -i "s|Terminal=true|Terminal=false|g" ~/.local/share/applications/Helix.desktop
+Please note: there is no icon for Helix yet, so the system default will be used.
+Finishing up the installation
+To make sure everything is set up as expected you should finally run the helix healthcheck via
+hx --health
+For more information on the information displayed in the health check results refer to Healthcheck.
+Building tree-sitter grammars
+Tree-sitter grammars must be fetched and compiled if not pre-packaged.
+Fetch grammars with hx --grammar fetch (requires git) and compile them
+with hx --grammar build (requires a C++ compiler).
Installing language servers
+Language servers can optionally be installed if you want their features (auto-complete, diagnostics etc.). +Follow the instructions on the wiki page to add your language servers of choice.

Insert mode
+Insert mode bindings are somewhat minimal by default. Helix is designed to +be a modal editor, and this is reflected in the user experience and internal +mechanics. For example, changes to the text are only saved for undos when +escaping from insert mode to normal mode. For this reason, new users are +strongly encouraged to learn the modal editing paradigm to get the smoothest +experience.
+| Key | Description | Command |
|---|---|---|
Escape | Switch to normal mode | normal_mode |
Ctrl-s | Commit undo checkpoint | commit_undo_checkpoint |
Ctrl-x | Autocomplete | completion |
Ctrl-r | Insert a register content | insert_register |
Ctrl-w, Alt-Backspace | Delete previous word | delete_word_backward |
Alt-d, Alt-Delete | Delete next word | delete_word_forward |
Ctrl-u | Delete to start of line | kill_to_line_start |
Ctrl-k | Delete to end of line | kill_to_line_end |
Ctrl-h, Backspace | Delete previous char | delete_char_backward |
Ctrl-d, Delete | Delete next char | delete_char_forward |
Ctrl-j, Enter | Insert new line | insert_newline |
These keys are not recommended, but are included for new users less familiar +with modal editors.
+| Key | Description | Command |
|---|---|---|
Up | Move to previous line | move_line_up |
Down | Move to next line | move_line_down |
Left | Backward a char | move_char_left |
Right | Forward a char | move_char_right |
PageUp | Move one page up | page_up |
PageDown | Move one page down | page_down |
Home | Move to line start | goto_line_start |
End | Move to line end | goto_line_end_newline |
If you want to disable them in insert mode as you become more comfortable with modal editing, you can use
+the following in your config.toml:
[keys.insert]
+up = "no_op"
+down = "no_op"
+left = "no_op"
+right = "no_op"
+pageup = "no_op"
+pagedown = "no_op"
+home = "no_op"
+end = "no_op"
+Select / extend mode
+This mode echoes Normal mode, but changes any movements to extend
+selections rather than replace them. Goto motions are also changed to
+extend, so that vgl for example extends the selection to the end of
+the line.
Search is also affected. By default, n and N will remove the current
+selection and select the next instance of the search term. Toggling this
+mode before pressing n or N makes it possible to keep the current
+selection. Toggling it on and off during your iterative searching allows
+you to selectively add search terms to your selections.

+| Key | Description |
|---|---|
Shift-Tab, Up, Ctrl-p | Previous entry |
Tab, Down, Ctrl-n | Next entry |

+File-type detection and the
+
+
+
+
+
+
+
+
+
+
+ Languages
+Language-specific settings and settings for language servers are configured
+in languages.toml files.
languages.toml files
+There are three possible languages.toml files. The first is compiled into
+Helix and lives in the Helix repository.
+This provides the default configurations for languages and language servers.
You may define a languages.toml in your configuration directory
+which overrides values from the built-in language configuration. For example
+to disable auto-LSP-formatting in Rust:
# in <config_dir>/helix/languages.toml
+
+[[language]]
+name = "rust"
+auto-format = false
+Language configuration may also be overridden local to a project by creating
+a languages.toml file under a .helix directory. Its settings will be merged
+with the language configuration in the configuration directory and the built-in
+configuration.
Language configuration
+Each language is configured by adding a [[language]] section to a
+languages.toml file. For example:
[[language]]
+name = "mylang"
+scope = "source.mylang"
+injection-regex = "^mylang$"
+file-types = ["mylang", "myl"]
+comment-token = "#"
+indent = { tab-width = 2, unit = " " }
+language-server = { command = "mylang-lsp", args = ["--stdio"] }
+formatter = { command = "mylang-formatter" , args = ["--stdin"] }
+These configuration keys are available:
+| Key | Description |
|---|---|
name | The name of the language |
scope | A string like source.js that identifies the language. Currently, we strive to match the scope names used by popular TextMate grammars and by the Linguist library. Usually source.<name> or text.<name> in case of markup languages |
injection-regex | regex pattern that will be tested against a language name in order to determine whether this language should be used for a potential language injection site. |
file-types | The filetypes of the language, for example ["yml", "yaml"]. See the file-type detection section below. |
shebangs | The interpreters from the shebang line, for example ["sh", "bash"] |
roots | A set of marker files to look for when trying to find the workspace root. For example Cargo.lock, yarn.lock |
auto-format | Whether to autoformat this language when saving |
diagnostic-severity | Minimal severity of diagnostic for it to be displayed. (Allowed values: Error, Warning, Info, Hint) |
comment-token | The token to use as a comment-token |
indent | The indent to use. Has sub keys tab-width and unit |
language-server | The Language Server to run. See the Language Server configuration section below. |
config | Language Server configuration |
grammar | The tree-sitter grammar to use (defaults to the value of name) |
formatter | The formatter for the language, it will take precedence over the lsp when defined. The formatter must be able to take the original file as input from stdin and write the formatted file to stdout |
max-line-length | Maximum line length. Used for the :reflow command |
File-type detection and the file-types key
+Helix determines which language configuration to use with the file-types key
+from the above section. file-types is a list of strings or tables, for
+example:
file-types = ["Makefile", "toml", { suffix = ".git/config" }]
+When determining a language configuration to use, Helix searches the file-types +with the following priorities:
+-
+
- Exact match: if the filename of a file is an exact match of a string in a
+
file-typeslist, that language wins. In the example above,"Makefile"+will match againstMakefilefiles.
+ - Extension: if there are no exact matches, any
file-typesstring that +matches the file extension of a given file wins. In the example above, the +"toml"matches files likeCargo.tomlorlanguages.toml.
+ - Suffix: if there are still no matches, any values in
suffixtables +are checked against the full path of the given file. In the example above, +the{ suffix = ".git/config" }would match against anyconfigfiles +in.gitdirectories. Note:/is used as the directory separator but is +replaced at runtime with the appropriate path separator for the operating +system, so this rule would match against.git\configfiles on Windows.
+
Language Server configuration
+The language-server field takes the following keys:
| Key | Description |
|---|---|
command | The name of the language server binary to execute. Binaries must be in $PATH |
args | A list of arguments to pass to the language server binary |
timeout | The maximum time a request to the language server may take, in seconds. Defaults to 20 |
language-id | The language name to pass to the language server. Some language servers support multiple languages and use this field to determine which one is being served in a buffer |
The top-level config field is used to configure the LSP initialization options. A format
+sub-table within config can be used to pass extra formatting options to
+Document Formatting Requests.
+For example with typescript:
[[language]]
+name = "typescript"
+auto-format = true
+# pass format options according to https://github.com/typescript-language-server/typescript-language-server#workspacedidchangeconfiguration omitting the "[language].format." prefix.
+config = { format = { "semicolons" = "insert", "insertSpaceBeforeFunctionParenthesis" = true } }
+Tree-sitter grammar configuration
+The source for a language's tree-sitter grammar is specified in a [[grammar]]
+section in languages.toml. For example:
[[grammar]]
+name = "mylang"
+source = { git = "https://github.com/example/mylang", rev = "a250c4582510ff34767ec3b7dcdd3c24e8c8aa68" }
+Grammar configuration takes these keys:
+| Key | Description |
|---|---|
name | The name of the tree-sitter grammar |
source | The method of fetching the grammar - a table with a schema defined below |
Where source is a table with either these keys when using a grammar from a
+git repository:
| Key | Description |
|---|---|
git | A git remote URL from which the grammar should be cloned |
rev | The revision (commit hash or tag) which should be fetched |
subpath | A path within the grammar directory which should be built. Some grammar repositories host multiple grammars (for example tree-sitter-typescript and tree-sitter-ocaml) in subdirectories. This key is used to point hx --grammar build to the correct path for compilation. When omitted, the root of repository is used |
Choosing grammars
+You may use a top-level use-grammars key to control which grammars are
+fetched and built when using hx --grammar fetch and hx --grammar build.
# Note: this key must come **before** the [[language]] and [[grammar]] sections
+use-grammars = { only = [ "rust", "c", "cpp" ] }
+# or
+use-grammars = { except = [ "yaml", "json" ] }
+When omitted, all grammars are fetched and built.

+ Helix
+Docs for bleeding edge master can be found at +https://docs.helix-editor.com/master.
+See the usage section for a quick overview of the editor, keymap +section for all available keybindings and the configuration section +for defining custom keybindings, setting themes, etc. +For everything else (e.g., how to install supported language servers), see the Helix Wiki.
+Refer the FAQ for common questions.
+Installation
+We provide pre-built binaries on the GitHub Releases page.
+
OSX
+Helix is available in homebrew-core:
+brew install helix
+Linux
+NixOS
+A flake containing the package is available in
+the project root. The flake can also be used to spin up a reproducible development
+shell for working on Helix with nix develop.
Flake outputs are cached for each push to master using +Cachix. The flake is configured to +automatically make use of this cache assuming the user accepts +the new settings on first use.
+If you are using a version of Nix without flakes enabled you can
+install Cachix cli; cachix use helix will
+configure Nix to use cached outputs when possible.
Arch Linux
+Releases are available in the community repository.
A helix-git package is also available on the AUR, which builds the master branch.
+Fedora Linux
+You can install the COPR package for Helix via
+sudo dnf copr enable varlad/helix
+sudo dnf install helix
+Void Linux
+sudo xbps-install helix
+Windows
+Helix can be installed using Scoop, Chocolatey +or MSYS2.
+Scoop:
+scoop install helix
+Chocolatey:
+choco install helix
+MSYS2:
+pacman -S mingw-w64-i686-helix
+or
+pacman -S mingw-w64-x86_64-helix
+or
+pacman -S mingw-w64-ucrt-x86_64-helix
+Build from source
+git clone https://github.com/helix-editor/helix
+cd helix
+cargo install --path helix-term
+This will install the hx binary to $HOME/.cargo/bin and build tree-sitter grammars in ./runtime/grammars.
Helix also needs its runtime files so make sure to copy/symlink the runtime/ directory into the
+config directory (for example ~/.config/helix/runtime on Linux/macOS). This location can be overridden
+via the HELIX_RUNTIME environment variable.
| OS | Command |
|---|---|
| Windows (Cmd) | xcopy /e /i runtime %AppData%\helix\runtime |
| Windows (PowerShell) | xcopy /e /i runtime $Env:AppData\helix\runtime |
| Linux / macOS | ln -s $PWD/runtime ~/.config/helix/runtime |
Starting with Windows Vista you can also create symbolic links on Windows. Note that this requires +elevated privileges - i.e. PowerShell or Cmd must be run as administrator.
+PowerShell:
+New-Item -ItemType SymbolicLink -Target "runtime" -Path "$Env:AppData\helix\runtime"
+Cmd:
+cd %appdata%\helix
+mklink /D runtime "<helix-repo>\runtime"
+The runtime location can be overridden via the HELIX_RUNTIME environment variable.
++NOTE: if
+HELIX_RUNTIMEis set prior to callingcargo install --path helix-term, +tree-sitter grammars will be built in$HELIX_RUNTIME/grammars.
If you plan on keeping the repo locally, an alternative to copying/symlinking
+runtime files is to set HELIX_RUNTIME=/path/to/helix/runtime
+(HELIX_RUNTIME=$PWD/runtime if you're in the helix repo directory).
To use Helix in desktop environments that supports XDG desktop menu, including Gnome and KDE, copy the provided .desktop file to the correct folder:
cp contrib/Helix.desktop ~/.local/share/applications
+To use another terminal than the default, you will need to modify the .desktop file. For example, to use kitty:
sed -i "s|Exec=hx %F|Exec=kitty hx %F|g" ~/.local/share/applications/Helix.desktop
+sed -i "s|Terminal=true|Terminal=false|g" ~/.local/share/applications/Helix.desktop
+Please note: there is no icon for Helix yet, so the system default will be used.
+Finishing up the installation
+To make sure everything is set up as expected you should finally run the helix healthcheck via
+hx --health
+For more information on the information displayed in the health check results refer to Healthcheck.
+Building tree-sitter grammars
+Tree-sitter grammars must be fetched and compiled if not pre-packaged.
+Fetch grammars with hx --grammar fetch (requires git) and compile them
+with hx --grammar build (requires a C++ compiler).
Installing language servers
+Language servers can optionally be installed if you want their features (auto-complete, diagnostics etc.). +Follow the instructions on the wiki page to add your language servers of choice.
+Usage
+(Currently not fully documented, see the keymappings list for more.)
+See tutor (accessible via hx --tutor or :tutor) for a vimtutor-like introduction.
Registers
+Vim-like registers can be used to yank and store text to be pasted later. Usage is similar, with " being used to select a register:
-
+
"ay- Yank the current selection to registera.
+"op- Paste the text in registeroafter the selection.
+
If there is a selected register before invoking a change or delete command, the selection will be stored in the register and the action will be carried out:
+-
+
"hc- Store the selection in registerhand then change it (delete and enter insert mode).
+"md- Store the selection in registermand delete it.
+
Special Registers
+| Register character | Contains |
|---|---|
/ | Last search |
: | Last executed command |
" | Last yanked text |
_ | Black hole |
++There is no special register for copying to system clipboard, instead special commands and keybindings are provided. See the keymap for the specifics. +The black hole register works as a no-op register, meaning no data will be written to / read from it.
+
Surround
+Functionality similar to vim-surround is built into +helix. The keymappings have been inspired from vim-sandwich:
+
-
+
ms- Add surround characters
+mr- Replace surround characters
+md- Delete surround characters
+
ms acts on a selection, so select the text first and use ms<char>. mr and md work
+on the closest pairs found and selections are not required; use counts to act in outer pairs.
It can also act on multiple selections (yay!). For example, to change every occurrence of (use) to [use]:
-
+
%to select the whole file
+sto split the selections on a search term
+- Input
useand hit Enter
+ mr([to replace the parens with square brackets
+
Multiple characters are currently not supported, but planned.
+Syntax-tree Motions
+Alt-p, Alt-o, Alt-i, and Alt-n (or Alt and arrow keys) move the primary
+selection according to the selection's place in the syntax tree. Let's walk
+through an example to get familiar with them. Many languages have a syntax like
+so for function calls:
func(arg1, arg2, arg3)
+A function call might be parsed by tree-sitter into a tree like the following.
+(call
+ function: (identifier) ; func
+ arguments:
+ (arguments ; (arg1, arg2, arg3)
+ (identifier) ; arg1
+ (identifier) ; arg2
+ (identifier))) ; arg3
+Use :tree-sitter-subtree to view the syntax tree of the primary selection. In
+a more intuitive tree format:
┌────┐
+ │call│
+ ┌─────┴────┴─────┐
+ │ │
+┌─────▼────┐ ┌────▼────┐
+│identifier│ │arguments│
+│ "func" │ ┌────┴───┬─────┴───┐
+└──────────┘ │ │ │
+ │ │ │
+ ┌─────────▼┐ ┌────▼─────┐ ┌▼─────────┐
+ │identifier│ │identifier│ │identifier│
+ │ "arg1" │ │ "arg2" │ │ "arg3" │
+ └──────────┘ └──────────┘ └──────────┘
+Say we have a selection that wraps arg1. The selection is on the arg1 leaf
+in the tree above.
func([arg1], arg2, arg3)
+Using Alt-n would select the next sibling in the syntax tree: arg2.
func(arg1, [arg2], arg3)
+While Alt-o would expand the selection to the parent node. In the tree above we
+can see that we would select the arguments node.
func[(arg1, arg2, arg3)]
+There is also some nuanced behavior that prevents you from getting stuck on a
+node with no sibling. If we have a selection on arg1, Alt-p would bring us
+to the previous child node. Since arg1 doesn't have a sibling to its left,
+though, we climb the syntax tree and then take the previous selection. So
+Alt-p will move the selection over to the "func" identifier.
[func](arg1, arg2, arg3)
+Textobjects
+
+
-
+
ma- Select around the object (vain Vim,<alt-a>in Kakoune)
+mi- Select inside the object (viin Vim,<alt-i>in Kakoune)
+
Key after mi or ma | Textobject selected |
|---|---|
w | Word |
W | WORD |
p | Paragraph |
(, [, ', etc | Specified surround pairs |
m | Closest surround pair |
f | Function |
c | Class |
a | Argument/parameter |
o | Comment |
t | Test |
g | Change |
++NOTE:
+f,c, etc need a tree-sitter grammar active for the current +document and a special tree-sitter query file to work properly. Only +some grammars currently have the query file implemented. +Contributions are welcome!
Tree-sitter Textobject Based Navigation
+Navigating between functions, classes, parameters, etc is made
+possible by leveraging tree-sitter and textobjects queries. For
+example to move to the next function use ]f, to move to previous
+class use [c, and so on.
See the unimpaired section of the keybind +documentation for the full reference.
+++NOTE: This feature is dependent on tree-sitter based textobjects +and therefore requires the corresponding query file to work properly.

Insert mode
+Insert mode bindings are somewhat minimal by default. Helix is designed to +be a modal editor, and this is reflected in the user experience and internal +mechanics. For example, changes to the text are only saved for undos when +escaping from insert mode to normal mode. For this reason, new users are +strongly encouraged to learn the modal editing paradigm to get the smoothest +experience.
+| Key | Description | Command |
|---|---|---|
Escape | Switch to normal mode | normal_mode |
Ctrl-s | Commit undo checkpoint | commit_undo_checkpoint |
Ctrl-x | Autocomplete | completion |
Ctrl-r | Insert a register content | insert_register |
Ctrl-w, Alt-Backspace | Delete previous word | delete_word_backward |
Alt-d, Alt-Delete | Delete next word | delete_word_forward |
Ctrl-u | Delete to start of line | kill_to_line_start |
Ctrl-k | Delete to end of line | kill_to_line_end |
Ctrl-h, Backspace | Delete previous char | delete_char_backward |
Ctrl-d, Delete | Delete next char | delete_char_forward |
Ctrl-j, Enter | Insert new line | insert_newline |
These keys are not recommended, but are included for new users less familiar +with modal editors.
+| Key | Description | Command |
|---|---|---|
Up | Move to previous line | move_line_up |
Down | Move to next line | move_line_down |
Left | Backward a char | move_char_left |
Right | Forward a char | move_char_right |
PageUp | Move one page up | page_up |
PageDown | Move one page down | page_down |
Home | Move to line start | goto_line_start |
End | Move to line end | goto_line_end_newline |
If you want to disable them in insert mode as you become more comfortable with modal editing, you can use
+the following in your config.toml:
[keys.insert]
+up = "no_op"
+down = "no_op"
+left = "no_op"
+right = "no_op"
+pageup = "no_op"
+pagedown = "no_op"
+home = "no_op"
+end = "no_op"
+Select / extend mode
+This mode echoes Normal mode, but changes any movements to extend
+selections rather than replace them. Goto motions are also changed to
+extend, so that vgl for example extends the selection to the end of
+the line.
Search is also affected. By default, n and N will remove the current
+selection and select the next instance of the search term. Toggling this
+mode before pressing n or N makes it possible to keep the current
+selection. Toggling it on and off during your iterative searching allows
+you to selectively add search terms to your selections.

Migrating from Vim
+Helix's editing model is strongly inspired from Vim and Kakoune, and a notable
+difference from Vim (and the most striking similarity to Kakoune) is that Helix
+follows the selection → action model. This means that the whatever you are
+going to act on (a word, a paragraph, a line, etc) is selected first and the
+action itself (delete, change, yank, etc) comes second. A cursor is simply a
+single width selection.
See also Kakoune's Migrating from Vim and Helix's Migrating from Vim.
+++TODO: Mention textobjects, surround, registers
+
Configuration
+To override global configuration parameters, create a config.toml file located in your config directory:
-
+
- Linux and Mac:
~/.config/helix/config.toml
+ - Windows:
%AppData%\helix\config.toml
+
++Hint: You can easily open the config file by typing
+:config-openwithin Helix normal mode.
Example config:
+theme = "onedark"
+
+[editor]
+line-number = "relative"
+mouse = false
+
+[editor.cursor-shape]
+insert = "bar"
+normal = "block"
+select = "underline"
+
+[editor.file-picker]
+hidden = false
+You may also specify a file to use for configuration with the -c or
+--config CLI argument: hx -c path/to/custom-config.toml.
It is also possible to trigger configuration file reloading by sending the USR1
+signal to the helix process, e.g. via pkill -USR1 hx. This is only supported
+on unix operating systems.

+skip-levels = 1
+Themes
+To use a theme add theme = "<name>" to your config.toml at the very top of the file before the first section or select it during runtime using :theme <name>.
Creating a theme
+Create a file with the name of your theme as file name (i.e mytheme.toml) and place it in your themes directory (i.e ~/.config/helix/themes). The directory might have to be created beforehand.
The names "default" and "base16_default" are reserved for the builtin themes and cannot be overridden by user defined themes.
+The default theme.toml can be found here, and user submitted themes here.
+Each line in the theme file is specified as below:
+key = { fg = "#ffffff", bg = "#000000", underline = { color = "#ff0000", style = "curl"}, modifiers = ["bold", "italic"] }
+where key represents what you want to style, fg specifies the foreground color, bg the background color, underline the underline style/color, and modifiers is a list of style modifiers. bg, underline and modifiers can be omitted to defer to the defaults.
To specify only the foreground color:
+key = "#ffffff"
+if the key contains a dot '.', it must be quoted to prevent it being parsed as a dotted key.
"key.key" = "#ffffff"
+Color palettes
+It's recommended define a palette of named colors, and refer to them from the
+configuration values in your theme. To do this, add a table called
+palette to your theme file:
"ui.background" = "white"
+"ui.text" = "black"
+
+[palette]
+white = "#ffffff"
+black = "#000000"
+Remember that the [palette] table includes all keys after its header,
+so you should define the palette after normal theme options.
The default palette uses the terminal's default 16 colors, and the colors names
+are listed below. The [palette] section in the config file takes precedence
+over it and is merged into the default palette.
| Color Name |
|---|
black |
red |
green |
yellow |
blue |
magenta |
cyan |
gray |
light-red |
light-green |
light-yellow |
light-blue |
light-magenta |
light-cyan |
light-gray |
white |
Modifiers
+The following values may be used as modifiers.
+Less common modifiers might not be supported by your terminal emulator.
+| Modifier |
|---|
bold |
dim |
italic |
underlined |
slow_blink |
rapid_blink |
reversed |
hidden |
crossed_out |
++Note: The
+underlinedmodifier is deprecated and only available for backwards compatibility. +Its behavior is equivalent to settingunderline.style="line".
Underline Style
+One of the following values may be used as a value for underline.style.
Some styles might not be supported by your terminal emulator.
+| Modifier |
|---|
line |
curl |
dashed |
dot |
double_line |
Inheritance
+Extend upon other themes by setting the inherits property to an existing theme.
inherits = "boo_berry"
+
+# Override the theming for "keyword"s:
+"keyword" = { fg = "gold" }
+
+# Override colors in the palette:
+[palette]
+berry = "#2A2A4D"
+Scopes
+The following is a list of scopes available to use for styling.
+Syntax highlighting
+These keys match tree-sitter scopes.
+For a given highlight produced, styling will be determined based on the longest matching theme key. For example, the highlight function.builtin.static would match the key function.builtin rather than function.
We use a similar set of scopes as +SublimeText. See also +TextMate scopes.

+Key Remapping
+One-way key remapping is temporarily supported via a simple TOML configuration +file. (More powerful solutions such as rebinding via commands will be +available in the future).
+To remap keys, write a config.toml file in your helix configuration
+directory (default ~/.config/helix in Linux systems) with a structure like
+this:
# At most one section each of 'keys.normal', 'keys.insert' and 'keys.select'
+[keys.normal]
+C-s = ":w" # Maps the Ctrl-s to the typable command :w which is an alias for :write (save file)
+C-o = ":open ~/.config/helix/config.toml" # Maps the Ctrl-o to opening of the helix config file
+a = "move_char_left" # Maps the 'a' key to the move_char_left command
+w = "move_line_up" # Maps the 'w' key move_line_up
+"C-S-esc" = "extend_line" # Maps Ctrl-Shift-Escape to extend_line
+g = { a = "code_action" } # Maps `ga` to show possible code actions
+"ret" = ["open_below", "normal_mode"] # Maps the enter key to open_below then re-enter normal mode
+
+[keys.insert]
+"A-x" = "normal_mode" # Maps Alt-X to enter normal mode
+j = { k = "normal_mode" } # Maps `jk` to exit insert mode
+++NOTE: Typable commands can also be remapped, remember to keep the
+:prefix to indicate it's a typable command.
Ctrl, Shift and Alt modifiers are encoded respectively with the prefixes
+C-, S- and A-. Special keys are encoded as follows:
| Key name | Representation |
|---|---|
| Backspace | "backspace" |
| Space | "space" |
| Return/Enter | "ret" |
| - | "minus" |
| Left | "left" |
| Right | "right" |
| Up | "up" |
| Down | "down" |
| Home | "home" |
| End | "end" |
| Page Up | "pageup" |
| Page Down | "pagedown" |
| Tab | "tab" |
| Delete | "del" |
| Insert | "ins" |
| Null | "null" |
| Escape | "esc" |
Keys can be disabled by binding them to the no_op command.
Commands can be found at Keymap Commands.
+++Commands can also be found in the source code at
+helix-term/src/commands.rsat the invocation ofstatic_commands!macro and theTypableCommandList.
Languages
+Language-specific settings and settings for language servers are configured
+in languages.toml files.
languages.toml files
+There are three possible languages.toml files. The first is compiled into
+Helix and lives in the Helix repository.
+This provides the default configurations for languages and language servers.
You may define a languages.toml in your configuration directory
+which overrides values from the built-in language configuration. For example
+to disable auto-LSP-formatting in Rust:
# in <config_dir>/helix/languages.toml
+
+[[language]]
+name = "rust"
+auto-format = false
+Language configuration may also be overridden local to a project by creating
+a languages.toml file under a .helix directory. Its settings will be merged
+with the language configuration in the configuration directory and the built-in
+configuration.
Language configuration
+Each language is configured by adding a [[language]] section to a
+languages.toml file. For example:
[[language]]
+name = "mylang"
+scope = "source.mylang"
+injection-regex = "^mylang$"
+file-types = ["mylang", "myl"]
+comment-token = "#"
+indent = { tab-width = 2, unit = " " }
+language-server = { command = "mylang-lsp", args = ["--stdio"] }
+formatter = { command = "mylang-formatter" , args = ["--stdin"] }
+These configuration keys are available:
+| Key | Description |
|---|---|
name | The name of the language |
scope | A string like source.js that identifies the language. Currently, we strive to match the scope names used by popular TextMate grammars and by the Linguist library. Usually source.<name> or text.<name> in case of markup languages |
injection-regex | regex pattern that will be tested against a language name in order to determine whether this language should be used for a potential language injection site. |
file-types | The filetypes of the language, for example ["yml", "yaml"]. See the file-type detection section below. |
shebangs | The interpreters from the shebang line, for example ["sh", "bash"] |
roots | A set of marker files to look for when trying to find the workspace root. For example Cargo.lock, yarn.lock |
auto-format | Whether to autoformat this language when saving |
diagnostic-severity | Minimal severity of diagnostic for it to be displayed. (Allowed values: Error, Warning, Info, Hint) |
comment-token | The token to use as a comment-token |
indent | The indent to use. Has sub keys tab-width and unit |
language-server | The Language Server to run. See the Language Server configuration section below. |
config | Language Server configuration |
grammar | The tree-sitter grammar to use (defaults to the value of name) |
formatter | The formatter for the language, it will take precedence over the lsp when defined. The formatter must be able to take the original file as input from stdin and write the formatted file to stdout |
max-line-length | Maximum line length. Used for the :reflow command |
File-type detection and the file-types key
+Helix determines which language configuration to use with the file-types key
+from the above section. file-types is a list of strings or tables, for
+example:
file-types = ["Makefile", "toml", { suffix = ".git/config" }]
+When determining a language configuration to use, Helix searches the file-types +with the following priorities:
+-
+
- Exact match: if the filename of a file is an exact match of a string in a
+
file-typeslist, that language wins. In the example above,"Makefile"+will match againstMakefilefiles.
+ - Extension: if there are no exact matches, any
file-typesstring that +matches the file extension of a given file wins. In the example above, the +"toml"matches files likeCargo.tomlorlanguages.toml.
+ - Suffix: if there are still no matches, any values in
suffixtables +are checked against the full path of the given file. In the example above, +the{ suffix = ".git/config" }would match against anyconfigfiles +in.gitdirectories. Note:/is used as the directory separator but is +replaced at runtime with the appropriate path separator for the operating +system, so this rule would match against.git\configfiles on Windows.
+
Language Server configuration
+The language-server field takes the following keys:
| Key | Description |
|---|---|
command | The name of the language server binary to execute. Binaries must be in $PATH |
args | A list of arguments to pass to the language server binary |
timeout | The maximum time a request to the language server may take, in seconds. Defaults to 20 |
language-id | The language name to pass to the language server. Some language servers support multiple languages and use this field to determine which one is being served in a buffer |
The top-level config field is used to configure the LSP initialization options. A format
+sub-table within config can be used to pass extra formatting options to
+Document Formatting Requests.
+For example with typescript:
[[language]]
+name = "typescript"
+auto-format = true
+# pass format options according to https://github.com/typescript-language-server/typescript-language-server#workspacedidchangeconfiguration omitting the "[language].format." prefix.
+config = { format = { "semicolons" = "insert", "insertSpaceBeforeFunctionParenthesis" = true } }
+Tree-sitter grammar configuration
+The source for a language's tree-sitter grammar is specified in a [[grammar]]
+section in languages.toml. For example:
[[grammar]]
+name = "mylang"
+source = { git = "https://github.com/example/mylang", rev = "a250c4582510ff34767ec3b7dcdd3c24e8c8aa68" }
+Grammar configuration takes these keys:
+| Key | Description |
|---|---|
name | The name of the tree-sitter grammar |
source | The method of fetching the grammar - a table with a schema defined below |
Where source is a table with either these keys when using a grammar from a
+git repository:
| Key | Description |
|---|---|
git | A git remote URL from which the grammar should be cloned |
rev | The revision (commit hash or tag) which should be fetched |
subpath | A path within the grammar directory which should be built. Some grammar repositories host multiple grammars (for example tree-sitter-typescript and tree-sitter-ocaml) in subdirectories. This key is used to point hx --grammar build to the correct path for compilation. When omitted, the root of repository is used |
Choosing grammars
+You may use a top-level use-grammars key to control which grammars are
+fetched and built when using hx --grammar fetch and hx --grammar build.
# Note: this key must come **before** the [[language]] and [[grammar]] sections
+use-grammars = { only = [ "rust", "c", "cpp" ] }
+# or
+use-grammars = { except = [ "yaml", "json" ] }
+When omitted, all grammars are fetched and built.
+Guides
+This section contains guides for adding new language server configurations, +tree-sitter grammars, textobject queries, etc.
+Adding languages
+Language configuration
+To add a new language, you need to add a [[language]] entry to the
+languages.toml (see the language configuration section).
When adding a new language or Language Server configuration for an existing
+language, run cargo xtask docgen to add the new configuration to the
+Language Support docs before creating a pull request.
+When adding a Language Server configuration, be sure to update the
+Language Server Wiki with installation notes.
Grammar configuration
+If a tree-sitter grammar is available for the language, add a new [[grammar]]
+entry to languages.toml.
You may use the source.path key rather than source.git with an absolute path
+to a locally available grammar for testing, but switch to source.git before
+submitting a pull request.
Queries
+For a language to have syntax-highlighting and indentation among
+other things, you have to add queries. Add a directory for your
+language with the path runtime/queries/<name>/. The tree-sitter
+website
+gives more info on how to write queries.
++NOTE: When evaluating queries, the first matching query takes +precedence, which is different from other editors like Neovim where +the last matching query supersedes the ones before it. See +this issue for an example.
+
Common Issues
+-
+
-
+
If you get errors when running after switching branches, you may have to update the tree-sitter grammars. Run
+hx --grammar fetchto fetch the grammars andhx --grammar buildto build any out-of-date grammars.
+ -
+
If a parser is segfaulting or you want to remove the parser, make sure to remove the compiled parser in
+runtime/grammar/<name>.so
+
Adding Textobject Queries
+Textobjects that are language specific (like functions, classes, etc)
+require an accompanying tree-sitter grammar and a textobjects.scm query file
+to work properly. Tree-sitter allows us to query the source code syntax tree
+and capture specific parts of it. The queries are written in a lisp dialect.
+More information on how to write queries can be found in the official tree-sitter
+documentation.
Query files should be placed in runtime/queries/{language}/textobjects.scm
+when contributing. Note that to test the query files locally you should put
+them under your local runtime directory (~/.config/helix/runtime on Linux
+for example).
The following captures are recognized:
+| Capture Name |
|---|
function.inside |
function.around |
class.inside |
class.around |
test.inside |
test.around |
parameter.inside |
comment.inside |
comment.around |
Example query files can be found in the helix GitHub repository.
+Queries for Textobject Based Navigation
+Tree-sitter based navigation is done using captures in the +following order:
+-
+
object.movement
+object.around
+object.inside
+
For example if a function.around capture has been already defined for a language
+in it's textobjects.scm file, function navigation should also work automatically.
+function.movement should be defined only if the node captured by function.around
+doesn't make sense in a navigation context.
Adding Indent Queries
+Helix uses tree-sitter to correctly indent new lines. This requires
+a tree-sitter grammar and an indent.scm query file placed in
+runtime/queries/{language}/indents.scm. The indentation for a line
+is calculated by traversing the syntax tree from the lowest node at the
+beginning of the new line. Each of these nodes contributes to the total
+indent when it is captured by the query (in what way depends on the name
+of the capture).
Note that it matters where these added indents begin. For example, +multiple indent level increases that start on the same line only increase +the total indent level by 1.
+Scopes
+Added indents don't always apply to the whole node. For example, in most +cases when a node should be indented, we actually only want everything +except for its first line to be indented. For this, there are several +scopes (more scopes may be added in the future if required):
+-
+
-
+
+all: +This scope applies to the whole captured node. This is only different from +tailwhen the captured node is the first node on its line.
+ -
+
+tail: +This scope applies to everything except for the first line of the +captured node.
+
Every capture type has a default scope which should do the right thing
+in most situations. When a different scope is required, this can be
+changed by using a #set! declaration anywhere in the pattern:
(assignment_expression
+ right: (_) @indent
+ (#set! "scope" "all"))
+Capture Types
+-
+
-
+
+@indent(default scopetail): +Increase the indent level by 1. Multiple occurrences in the same line +don't stack. If there is at least one@indentand one@outdent+capture on the same line, the indent level isn't changed at all.
+ -
+
+@outdent(default scopeall): +Decrease the indent level by 1. The same rules as for@indentapply.
+ -
+
+@extend: +Extend the range of this node to the end of the line and to lines that +are indented more than the line that this node starts on. This is useful +for languages like Python, where for the purpose of indentation some nodes +(like functions or classes) should also contain indented lines that follow them.
+ -
+
+@extend.prevent-once: +Prevents the first extension of an ancestor of this node. For example, in Python +a return expression always ends the block that it is in. Note that this only stops the +extension of the next@extendcapture. If multiple ancestors are captured, +only the extension of the innermost one is prevented. All other ancestors are unaffected +(regardless of whether the innermost ancestor would actually have been extended).
+
Predicates
+In some cases, an S-expression cannot express exactly what pattern should be matched.
+For that, tree-sitter allows for predicates to appear anywhere within a pattern,
+similar to how #set! declarations work:
(some_kind
+ (child_kind) @indent
+ (#predicate? arg1 arg2 ...)
+)
+The number of arguments depends on the predicate that's used.
+Each argument is either a capture (@name) or a string ("some string").
+The following predicates are supported by tree-sitter:
-
+
-
+
+#eq?/#not-eq?: +The first argument (a capture) must/must not be equal to the second argument +(a capture or a string).
+ -
+
+#match?/#not-match?: +The first argument (a capture) must/must not match the regex given in the +second argument (a string).
+
Additionally, we support some custom predicates for indent queries:
+-
+
-
+
+#not-kind-eq?: +The kind of the first argument (a capture) must not be equal to the second +argument (a string).
+ -
+
+#same-line?/#not-same-line?: +The captures given by the 2 arguments must/must not start on the same line.

+ Key Remapping
+One-way key remapping is temporarily supported via a simple TOML configuration +file. (More powerful solutions such as rebinding via commands will be +available in the future).
+To remap keys, write a config.toml file in your helix configuration
+directory (default ~/.config/helix in Linux systems) with a structure like
+this:
# At most one section each of 'keys.normal', 'keys.insert' and 'keys.select'
+[keys.normal]
+C-s = ":w" # Maps the Ctrl-s to the typable command :w which is an alias for :write (save file)
+C-o = ":open ~/.config/helix/config.toml" # Maps the Ctrl-o to opening of the helix config file
+a = "move_char_left" # Maps the 'a' key to the move_char_left command
+w = "move_line_up" # Maps the 'w' key move_line_up
+"C-S-esc" = "extend_line" # Maps Ctrl-Shift-Escape to extend_line
+g = { a = "code_action" } # Maps `ga` to show possible code actions
+"ret" = ["open_below", "normal_mode"] # Maps the enter key to open_below then re-enter normal mode
+
+[keys.insert]
+"A-x" = "normal_mode" # Maps Alt-X to enter normal mode
+j = { k = "normal_mode" } # Maps `jk` to exit insert mode
+++NOTE: Typable commands can also be remapped, remember to keep the
+:prefix to indicate it's a typable command.
Ctrl, Shift and Alt modifiers are encoded respectively with the prefixes
+C-, S- and A-. Special keys are encoded as follows:
| Key name | Representation |
|---|---|
| Backspace | "backspace" |
| Space | "space" |
| Return/Enter | "ret" |
| - | "minus" |
| Left | "left" |
| Right | "right" |
| Up | "up" |
| Down | "down" |
| Home | "home" |
| End | "end" |
| Page Up | "pageup" |
| Page Down | "pagedown" |
| Tab | "tab" |
| Delete | "del" |
| Insert | "ins" |
| Null | "null" |
| Escape | "esc" |
Keys can be disabled by binding them to the no_op command.
Commands can be found at Keymap Commands.
+++ +Commands can also be found in the source code at
+helix-term/src/commands.rsat the invocation ofstatic_commands!macro and theTypableCommandList.
