select |
Cursor shape in select mode | block |
[editor.file-picker] Section
Set options for file picker and global search. Ignoring a file means it is not visible in the Helix file picker and global search.
All git related options are only enabled in a git repository.
| Key | Description | Default |
|---|---|---|
hidden |
Enables ignoring hidden files | true |
follow-symlinks |
Follow symlinks instead of ignoring them | true |

Ignore files can be placed locally as .ignore or put in your home directory as ~/.ignore. They support the usual ignore and negative ignore (unignore) rules used in .gitignore files.
Additionally, you can use Helix-specific ignore files by creating a local .helix/ignore file in the current workspace or a global ignore file located in your Helix config directory:
- Linux and Mac:
~/.config/helix/ignore - Windows:
%AppData%\helix\ignore
Example:
# unignore in file picker and global search
!.github/
!.gitignore
!.gitattributes
[editor.auto-pairs] Section
Enables automatic insertion of pairs to parentheses, brackets, etc. Can be a simple boolean value, or a specific mapping of pairs of single characters.
To disable auto-pairs altogether, set auto-pairs to false:
[editor]
auto-pairs = false # defaults to `true`
The default pairs are (){}[]''""``, but these can be customized by
setting auto-pairs to a TOML table:
[editor.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
'`' = '`'
'<' = '>'
Additionally, this setting can be used in a language config. Unless
the editor setting is false, this will override the editor config in
documents with this language.
Example languages.toml that adds <> and removes ''
[[language]]
name = "rust"
[language.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
'`' = '`'
'<' = '>'

[editor.whitespace.characters]
space = "·"
nbsp = "⍽"

[editor.gutters] Section
For simplicity, editor.gutters accepts an array of gutter types, which will
use default settings for all gutter components.
[editor]
gutters = ["diff", "diagnostics", "line-numbers", "spacer"]
To customize the behavior of gutters, the [editor.gutters] section must
be used. This section contains top level settings, as well as settings for
specific gutter components as subsections.
| Key | Description | Default |
|---|---|---|
layout |
A vector of gutters to display | ["diagnostics", "spacer", "line-numbers", "spacer", "diff"] |
Example:
[editor.gutters]
layout = ["diff", "diagnostics", "line-numbers", "spacer"]
[editor.gutters.line-numbers] Section
Options for the line number gutter
| Key | Description | Default |
|---|---|---|
min-width |
The minimum number of characters to use | 3 |
Example:
[editor.gutters.line-numbers]
min-width = 1
[editor.gutters.diagnostics] Section
Currently unused
[editor.gutters.diff] Section
The diff gutter option displays colored bars indicating whether a git diff represents that a line was added, removed or changed.
These colors are controlled by the theme attributes diff.plus, diff.minus and diff.delta.
Other diff providers will eventually be supported by a future plugin system.
There are currently no options for this section.
[editor.gutters.spacer] Section
Currently unused
[editor.soft-wrap] Section
Options for soft wrapping lines that exceed the view width:
| Key | Description | Default |
|---|---|---|
enable |
Whether soft wrapping is enabled. | false |
max-wrap |
Maximum free space left at the end of the line. | 20 |
max-indent-retain |
Maximum indentation to carry over when soft wrapping a line. | 40 |
wrap-indicator |
Text inserted before soft wrapped lines, highlighted with ui.virtual.wrap |
↪ |
wrap-at-text-width |
Soft wrap at text-width instead of using the full viewport size. |
false |
Example:
[editor.soft-wrap]
enable = true
max-wrap = 25 # increase value to reduce forced mid-word wrapping
max-indent-retain = 0
wrap-indicator = "" # set wrap-indicator to "" to hide it
[editor.smart-tab] Section
Options for navigating and editing using tab key.
| Key | Description | Default |
|---|---|---|
enable |
If set to true, then when the cursor is in a position with non-whitespace to its left, instead of inserting a tab, it will run move_parent_node_end. If there is only whitespace to the left, then it inserts a tab as normal. With the default bindings, to explicitly insert a tab character, press Shift-tab. |
true |
supersede-menu |
Normally, when a menu is on screen, such as when auto complete is triggered, the tab key is bound to cycling through the items. This means when menus are on screen, one cannot use the tab key to trigger the smart-tab command. If this option is set to true, the smart-tab command always takes precedence, which means one cannot use the tab key to cycle through menu items. One of the other bindings must be used instead, such as arrow keys or C-n/C-p. |
false |
Due to lack of support for S-tab in some terminals, the default keybindings don't fully embrace smart-tab editing experience. If you enjoy smart-tab navigation and a terminal that supports the Enhanced Keyboard protocol, consider setting extra keybindings:
[keys.normal]
tab = "move_parent_node_end"
S-tab = "move_parent_node_start"
[keys.insert]
S-tab = "move_parent_node_start"
[keys.select]
tab = "extend_parent_node_end"
S-tab = "extend_parent_node_start"
[editor.inline-diagnostics] Section
Options for rendering diagnostics inside the text like shown below
fn main() {
let foo = bar;
└─ no such value in this scope
}
| Key | Description | Default |
|---|---|---|
cursor-line |
The minimum severity that a diagnostic must have to be shown inline on the line that contains the primary cursor. Set to disable to not show any diagnostics inline. This option does not have any effect when in insert-mode and will only take effect 350ms after moving the cursor to a different line. |
"disable" |
other-lines |
The minimum severity that a diagnostic must have to be shown inline on a line that does not contain the cursor-line. Set to disable to not show any diagnostics inline. |
"disable" |
prefix-len |
How many horizontal bars ─ are rendered before the diagnostic text. |
1 |
max-wrap |
Equivalent of the editor.soft-wrap.max-wrap option for diagnostics. |
20 |
max-diagnostics |
Maximum number of diagnostics to render inline for a given line | 10 |
The (first) diagnostic with the highest severity that is not shown inline is rendered at the end of the line (as long as its severity is higher than the end-of-line-diagnostics config option):
fn main() {
let baz = 1;
let foo = bar; a local variable with a similar name exists: baz
└─ no such value in this scope
}
The new diagnostic rendering is not yet enabled by default. As soon as end of line or inline diagnostics are enabled the old diagnostics rendering is automatically disabled. The recommended default setting are:
end-of-line-diagnostics = "hint"
[editor.inline-diagnostics]
cursor-line = "warning" # show warnings and errors on the cursorline inline
-
By default, a progress spinner is shown in the statusline beside the file path. ↩︎
-
You may also have to activate them in the LSP config for them to appear, not just in Helix. Inlay hints in Helix are still being improved on and may be a little bit laggy/janky under some circumstances. Please report any bugs you see so we can fix them! ↩︎
