3346# Installation
3447
35−Packages are available for various distributions (see [Installation docs](https://docs.helix-editor.com/install.html)).
36−
37−If you would like to build from source:
38−
39−```shell
40−git clone https://github.com/helix-editor/helix
41−cd helix
42−cargo install --path helix-term
43−```
44−
45−This will install the `hx` binary to `$HOME/.cargo/bin` and build tree-sitter grammars.
46−If you want to customize your `languages.toml` config,
47−tree-sitter grammars may be manually fetched and built with `hx --grammar fetch` and `hx --grammar build`.
48−
49−Helix also needs its runtime files so make sure to copy/symlink the `runtime/` directory into the
50−config directory (for example `~/.config/helix/runtime` on Linux/macOS, or `%AppData%/helix/runtime` on Windows).
51−
52−| OS | command |
53−|-----------|-----------|
54−|windows |`xcopy runtime %AppData%/helix/runtime`|
55−|linux/macos|`ln -s $PWD/runtime ~/.config/helix/runtime`
56−
57−This location can be overridden via the `HELIX_RUNTIME` environment variable.
58−
59−Packages already solve this for you by wrapping the `hx` binary with a wrapper
60−that sets the variable to the install dir.
61−
62−> NOTE: running via cargo also doesn't require setting explicit `HELIX_RUNTIME` path, it will automatically
63−> detect the `runtime` directory in the project root.
64−
65−In order to use LSP features like auto-complete, you will need to

181+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.
182+
183+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:
184+- Linux and Mac: `~/.config/helix/ignore`
185+- Windows: `%AppData%\helix\ignore`

1−# Adding languages
1+# Adding new languages to Helix
2+
3+In order to add a new language to Helix, you will need to follow the steps
4+below.
25
36## Language configuration
47
5−To add a new language, you need to add a `[[language]]` entry to the
6−`languages.toml` (see the [language configuration section]).
8+1. Add a new `[[language]]` entry in the `languages.toml` file and provide the
9+ necessary configuration for the new language. For more information on
10+ language configuration, refer to the
11+ [language configuration section](../languages.md) of the documentation.
12+ A new language server can be added by extending the `[language-server]` table in the same file.
13+2. If you are adding a new language or updating an existing language server
14+ configuration, run the command `cargo xtask docgen` to update the
15+ [Language Support](../lang-support.md) documentation.
716
8−When adding a new language or Language Server configuration for an existing
9−language, run `cargo xtask docgen` to add the new configuration to the
10−[Language Support][lang-support] docs before creating a pull request.
11−When adding a Language Server configuration, be sure to update the
12−[Language Server Wiki][install-lsp-wiki] with installation notes.
17+> 💡 If you are adding a new Language Server configuration, make sure to update
18+> the
19+> [Language Server Wiki](https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers)
20+> with the installation instructions.
1321
1422## Grammar configuration
1523
16−If a tree-sitter grammar is available for the language, add a new `[[grammar]]`
17−entry to `languages.toml`.
18−
19−You may use the `source.path` key rather than `source.git` with an absolute path
20−to a locally available grammar for testing, but switch to `source.git` before
21−submitting a pull request.
24+1. If a tree-sitter grammar is available for the new language, add a new
25+ `[[grammar]]` entry to the `languages.toml` file.
26+2. If you are testing the grammar locally, you can use the `source.path` key
27+ with an absolute path to the grammar. However, before submitting a pull
28+ request, make sure to switch to using `source.git`.
2229
2330## Queries
2431
25−For a language to have syntax-highlighting and indentation among
26−other things, you have to add queries. Add a directory for your
27−language with the path `runtime/queries/<name>/`. The tree-sitter
28−[website](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries)
29−gives more info on how to write queries.
30−
31−> NOTE: When evaluating queries, the first matching query takes
32−precedence, which is different from other editors like neovim where
33−the last matching query supersedes the ones before it. See
34−[this issue][neovim-query-precedence] for an example.
35−
36−## Common Issues
37−
38−- If you get errors when running after switching branches, you may have to update the tree-sitter grammars. Run `hx --grammar fetch` to fetch the grammars and `hx --grammar build` to build any out-of-date grammars.
39−
40−- If a parser is segfaulting or you want to remove the parser, make sure to remove the compiled parser in `runtime/grammar/<name>.so`

32+1. In order to provide syntax highlighting and indentation for the new language,
33+ you will need to add queries.
34+2. Create a new directory for the language with the path
35+ `runtime/queries/<name>/`.
36+3. Refer to the
37+ [tree-sitter website](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries)
38+ for more information on writing queries.
39+4. A list of highlight captures can be found [on the themes page](https://docs.helix-editor.com/themes.html#scopes).
40+
41+> 💡 In Helix, the first matching query takes precedence when evaluating
42+> queries, which is different from other editors such as Neovim where the last
43+> matching query supersedes the ones before it. See
44+> [this issue](https://github.com/helix-editor/helix/pull/1170#issuecomment-997294090)
45+> for an example.
46+
47+## Common issues
48+
49+- If you encounter errors when running Helix after switching branches, you may
50+ need to update the tree-sitter grammars. Run the command `hx --grammar fetch`
51+ to fetch the grammars and `hx --grammar build` to build any out-of-date
52+ grammars.
53+- If a parser is causing a segfault, or you want to remove it, make sure to
54+ remove the compiled parser located at `runtime/grammars/<name>.so`.
55+- If you are attempting to add queries and Helix is unable to locate them, ensure that the environment variable `HELIX_RUNTIME` is set to the location of the `runtime` folder you're developing in.

1−# Adding Indent Queries
1+# Adding indent queries
22
3−Helix uses tree-sitter to correctly indent new lines. This requires
4−a tree-sitter grammar and an `indent.scm` query file placed in
5−`runtime/queries/{language}/indents.scm`. The indentation for a line
6−is calculated by traversing the syntax tree from the lowest node at the
7−beginning of the new line. Each of these nodes contributes to the total
8−indent when it is captured by the query (in what way depends on the name
9−of the capture).

13−the total indent level by 1.
13+the total indent level by 1. See [Capture types](#capture-types).
1414
15−## Scopes
15+By default, Helix uses the `hybrid` indentation heuristic. This means that
16+indent queries are not used to compute the expected absolute indentation of a
17+line but rather the expected difference in indentation between the new and an
18+already existing line. This difference is then added to the actual indentation
19+of the already existing line. Since this makes errors in the indent queries
20+harder to find, it is recommended to disable it when testing via
21+`:set indent-heuristic tree-sitter`. The rest of this guide assumes that
22+the `tree-sitter` heuristic is used.
1623
17−Added indents don't always apply to the whole node. For example, in most
18−cases when a node should be indented, we actually only want everything
19−except for its first line to be indented. For this, there are several
20−scopes (more scopes may be added in the future if required):
24+## Indent queries
2125
22−- `all`:
23−This scope applies to the whole captured node. This is only different from
24−`tail` when the captured node is the first node on its line.
26+When Helix is inserting a new line through `o`, `O`, or `<ret>`, to determine
27+the indent level for the new line, the query in `indents.scm` is run on the
28+document. The starting position of the query is the end of the line above where
29+a new line will be inserted.
2530
26−- `tail`:
27−This scope applies to everything except for the first line of the
28−captured node.
31+For `o`, the inserted line is the line below the cursor, so that starting
32+position of the query is the end of the current line.
2933
30−Every capture type has a default scope which should do the right thing
31−in most situations. When a different scope is required, this can be
32−changed by using a `#set!` declaration anywhere in the pattern:
33−```scm
34−(assignment_expression
35− right: (_) @indent
36− (#set! "scope" "all"))
34+```rust
35+fn need_hero(some_hero: Hero, life: Life) -> {
36+ matches!(some_hero, Hero { // ←─────────────────╮

42+// ↑ │
43+// ╰───────────────────────────────────────────────╯
44+ some_hero > life
45+}
3746```
3847
39−## Capture Types
48+For `O`, the newly inserted line is the *current* line, so the starting position
49+of the query is the end of the line above the cursor.
4050
41−- `@indent` (default scope `tail`):
42−Increase the indent level by 1. Multiple occurrences in the same line
43−don't stack. If there is at least one `@indent` and one `@outdent`
44−capture on the same line, the indent level isn't changed at all.
51+```rust
52+fn need_hero(some_hero: Hero, life: Life) -> { // ←─╮

61+```
62+
63+From this starting node, the syntax tree is traversed up until the root node.
64+Each indent capture is collected along the way, and then combined according to
65+their [capture types](#capture-types) and [scopes](#scopes) to a final indent
66+level for the line.
4567
68+### Capture types
69+
70+- `@indent` (default scope `tail`):
71+ Increase the indent level by 1. Multiple occurrences in the same line *do not*
72+ stack. If there is at least one `@indent` and one `@outdent` capture on the
73+ same line, the indent level isn't changed at all.
4674- `@outdent` (default scope `all`):
47−Decrease the indent level by 1. The same rules as for `@indent` apply.
75+ Decrease the indent level by 1. The same rules as for `@indent` apply.
76+- `@indent.always` (default scope `tail`):
77+ Increase the indent level by 1. Multiple occurrences on the same line *do*
78+ stack. The final indent level is `@indent.always` – `@outdent.always`. If
79+ an `@indent` and an `@indent.always` are on the same line, the `@indent` is
80+ ignored.
81+- `@outdent.always` (default scope `all`):
82+ Decrease the indent level by 1. The same rules as for `@indent.always` apply.
83+- `@align` (default scope `all`):
84+ Align everything inside this node to some anchor. The anchor is given
85+ by the start of the node captured by `@anchor` in the same pattern.
86+ Every pattern with an `@align` should contain exactly one `@anchor`.
87+ Indent (and outdent) for nodes below (in terms of their starting line)
88+ the `@align` node is added to the indentation required for alignment.
89+- `@extend`:
90+ Extend the range of this node to the end of the line and to lines that are
91+ indented more than the line that this node starts on. This is useful for
92+ languages like Python, where for the purpose of indentation some nodes (like
93+ functions or classes) should also contain indented lines that follow them.
94+- `@extend.prevent-once`:
95+ Prevents the first extension of an ancestor of this node. For example, in Python
96+ a return expression always ends the block that it is in. Note that this only
97+ stops the extension of the next `@extend` capture. If multiple ancestors are
98+ captured, only the extension of the innermost one is prevented. All other
99+ ancestors are unaffected (regardless of whether the innermost ancestor would
100+ actually have been extended).
101+
102+#### `@indent` / `@outdent`
103+
104+Consider this example:
105+
106+```rust
107+fn shout(things: Vec<Thing>) {
108+ // ↑
109+ // ├───────────────────────╮ indent level
110+ // @indent ├┄┄┄┄┄┄┄┄┄┄┄┄┄┄
111+ // │
112+ let it_all = |out| { things.filter(|thing| { // │ 1
113+ // ↑ ↑ │
114+ // ├───────────────────────┼─────┼┄┄┄┄┄┄┄┄┄┄┄┄┄┄
115+ // @indent @indent │

122+```
123+
124+```scm
125+((block) @indent)
126+["}" ")"] @outdent
127+```
128+
129+Note how on the second line, we have two blocks begin on the same line. In this
130+case, since both captures occur on the same line, they are combined and only
131+result in a net increase of 1. Also note that the closing `}`s are part of the
132+`@indent` captures, but the 3 `@outdent`s also combine into 1 and result in that
133+line losing one indent level.
134+
135+#### `@extend` / `@extend.prevent-once`
136+
137+For an example of where `@extend` can be useful, consider Python, which is
138+whitespace-sensitive.

169+
170+Without braces to catch the scope of the function, the smallest descendant of
171+the cursor on a line feed ends up being the entire inside of the class. Because
172+of this, it will miss the entire function node and its indent capture, leading
173+to an indent level one too small.
174+
175+To address this case, `@extend` tells helix to "extend" the captured node's span
176+to the line feed and every consecutive line that has a greater indent level than
177+the line of the node.

208+
209+Furthermore, there are some cases where extending to everything with a greater
210+indent level may not be desirable. Consider the `need_hero` function above. If
211+our cursor is on the last line of the returned expression.
212+
213+```python
214+class Hero:
215+ def __init__(self, strong, fast, sure, soon):

231+
232+In Python, the are a few tokens that will always end a scope, such as a return
233+statement. Since the scope ends, so should the indent level. But because the
234+function span is extended to every line with a greater indent level, a new line
235+would just continue on the same level. And an `@outdent` would not help us here
236+either, since it would cause everything in the parentheses to become outdented
237+as well.
238+
239+To help, we need to signal an end to the extension. We can do this with
240+`@extend.prevent-once`.

255+As mentioned before, normally if there is more than one `@indent` or `@outdent`
256+capture on the same line, they are combined.
257+
258+Sometimes, there are cases when you may want to ensure that every indent capture
259+is additive, regardless of how many occur on the same line. Consider this
260+example in YAML.

275+
276+In YAML, you often have lists of maps. In these cases, the syntax is such that
277+the list element and the map both start on the same line. But we really do want
278+to start an indentation for each of these so that subsequent keys in the map
279+hang over the list and align properly. This is where `@indent.always` helps.

49293## Predicates
50294
51295In some cases, an S-expression cannot express exactly what pattern should be matched.
52296For that, tree-sitter allows for predicates to appear anywhere within a pattern,
53297similar to how `#set!` declarations work:
298+
54299```scm

56301 (child_kind) @indent
57302 (#predicate? arg1 arg2 ...)
58303)
59304```
305+
60306The number of arguments depends on the predicate that's used.
61307Each argument is either a capture (`@name`) or a string (`"some string"`).
62308The following predicates are supported by tree-sitter:

327+- `#one-line?`/`#not-one-line?`:

329+
330+### Scopes
331+
332+Added indents don't always apply to the whole node. For example, in most
333+cases when a node should be indented, we actually only want everything
334+except for its first line to be indented. For this, there are several
335+scopes (more scopes may be added in the future if required):
336+
337+- `tail`:
338+This scope applies to everything except for the first line of the
339+captured node.
340+- `all`:
341+This scope applies to the whole captured node. This is only different from
342+`tail` when the captured node is the first node on its line.
343+
344+For example, imagine we have the following function

351+} // ←───────────────────────────────────┴──────────┴─ "}" @outdent
352+ // scope: "all"
353+```
354+
355+We can write the following query with the `#set!` declaration:
356+
357+ ```scm
358+ ((block) @indent
359+ (#set! "scope" "tail"))
360+ ("}" @outdent
361+ (#set! "scope" "all"))
362+ ```
363+
364+As we can see, the "tail" scope covers the node, except for the first line.
365+Everything up to and including the closing brace gets an indent level of 1.
366+Then, on the closing brace, we encounter an outdent with a scope of "all", which
367+means the first line is included, and the indent level is cancelled out on this
368+line. (Note these scopes are the defaults for `@indent` and `@outdent`—they are
369+written explicitly for demonstration.)

1+# Adding Injection Queries
2+
3+Writing language injection queries allows one to highlight a specific node as a different language.
4+In addition to the [standard][upstream-docs] language injection options used by tree-sitter, there
5+are a few Helix specific extensions that allow for more control.
6+
7+And example of a simple query that would highlight all strings as bash in Nix:
8+```scm
9+((string_expression (string_fragment) @injection.content)
10+ (#set! injection.language "bash"))
11+```
12+
13+## Capture Types
14+
15+- `@injection.language` (standard):
16+The captured node may contain the language name used to highlight the node captured by
17+`@injection.content`.
18+
19+- `@injection.content` (standard):
20+Marks the content to be highlighted as the language captured with `@injection.language` _et al_.
21+
22+- `@injection.filename` (extension):
23+The captured node may contain a filename with a file-extension known to Helix,
24+highlighting `@injection.content` as that language. This uses the language extensions defined in
25+both the default languages.toml distributed with Helix, as well as user defined languages.
26+
27+- `@injection.shebang` (extension):
28+The captured node may contain a shebang used to choose a language to highlight as. This also uses
29+the shebangs defined in the default and user `languages.toml`.
30+
31+## Settings
32+
33+- `injection.combined` (standard):
34+Indicates that all the matching nodes in the tree should have their content parsed as one
35+nested document.
36+
37+- `injection.language` (standard):
38+Forces the captured content to be highlighted as the given language
39+
40+- `injection.include-children` (standard):
41+Indicates that the content node’s entire text should be re-parsed, including the text of its child
42+nodes. By default, child nodes’ text will be excluded from the injected document.
43+
44+- `injection.include-unnamed-children` (extension):
45+Same as `injection.include-children` but only for unnamed child nodes.
46+
47+## Predicates
48+
49+- `#eq?` (standard):
50+The first argument (a capture) must be equal to the second argument
51+(a capture or a string).
52+
53+- `#match?` (standard):
54+The first argument (a capture) must match the regex given in the
55+second argument (a string).

256+#### Multiple runtime directories
257+
258+When Helix finds multiple runtime directories it will search through them for files in the
259+following order:
260+
261+1. `runtime/` sibling directory to `$CARGO_MANIFEST_DIR` directory (this is intended for
262+ developing and testing helix only).
263+2. `runtime/` subdirectory of OS-dependent helix user config directory.
264+3. `$HELIX_RUNTIME`
265+4. Distribution-specific fallback directory (set at compile time—not run time—
266+ with the `HELIX_DEFAULT_RUNTIME` environment variable)
267+5. `runtime/` subdirectory of path to Helix executable.
268+
269+This order also sets the priority for selecting which file will be used if multiple runtime
270+directories have files with the same name.
271+
272+#### Note to packagers
273+
274+If you are making a package of Helix for end users, to provide a good out of
275+the box experience, you should set the `HELIX_DEFAULT_RUNTIME` environment
276+variable at build time (before invoking `cargo build`) to a directory which
277+will store the final runtime files after installation. For example, say you want
278+to package the runtime into `/usr/lib/helix/runtime`. The rough steps a build
279+script could follow are:
280+
281+1. `export HELIX_DEFAULT_RUNTIME=/usr/lib/helix/runtime`
282+1. `cargo build --profile opt --locked --path helix-term`
283+1. `cp -r runtime $BUILD_DIR/usr/lib/helix/`
284+1. `cp target/opt/hx $BUILD_DIR/usr/bin/hx`
285+
286+This way the resulting `hx` binary will always look for its runtime directory in
287+`/usr/lib/helix/runtime` if the user has no custom runtime in `~/.config/helix`
288+or `HELIX_RUNTIME`.
289+
290+### Validating the installation
291+
292+To make sure everything is set up as expected you should run the Helix health
293+check:
294+
295+```sh
73296hx --health
74297```

304+If your desktop environment supports the
305+[XDG desktop menu](https://specifications.freedesktop.org/menu-spec/menu-spec-latest.html)
306+you can configure Helix to show up in the application menu by copying the

141+### Configuring Language Servers for a language
142+
143+The `language-servers` attribute in a language tells helix which language servers are used for this language.
144+
145+They have to be defined in the `[language-server]` table as described in the previous section.
146+
147+Different languages can use the same language server instance, e.g. `typescript-language-server` is used for javascript, jsx, tsx and typescript by default.
148+
149+In case multiple language servers are specified in the `language-servers` attribute of a `language`,
150+it's often useful to only enable/disable certain language-server features for these language servers.
151+
152+As an example, `efm-lsp-prettier` of the previous example is used only with a formatting command `prettier`,
153+so everything else should be handled by the `typescript-language-server` (which is configured by default).
154+The language configuration for typescript could look like this:
155+
156+```toml
157+[[language]]
158+name = "typescript"
159+language-servers = [ { name = "efm-lsp-prettier", only-features = [ "format" ] }, "typescript-language-server" ]
160+```
161+
162+or equivalent:
163+
164+```toml
165+[[language]]
166+name = "typescript"
167+language-servers = [ { name = "typescript-language-server", except-features = [ "format" ] }, "efm-lsp-prettier" ]
168+```
169+
170+Each requested LSP feature is prioritized in the order of the `language-servers` array.
171+For example, the first `goto-definition` supported language server (in this case `typescript-language-server`) will be taken for the relevant LSP request (command `goto_definition`).
172+The features `diagnostics`, `code-action`, `completion`, `document-symbols` and `workspace-symbols` are an exception to that rule, as they are working for all language servers at the same time and are merged together, if enabled for the language.
173+If no `except-features` or `only-features` is given, all features for the language server are enabled.
174+If a language server itself doesn't support a feature, the next language server array entry will be tried (and so on).
175+
176+The list of supported features is:
177+
178+- `format`
179+- `goto-definition`
180+- `goto-declaration`
181+- `goto-type-definition`
182+- `goto-reference`

720## Registers
821
9−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:
22+In Helix, registers are storage locations for text and other data, such as the
23+result of a search. Registers can be used to cut, copy, and paste text, similar
24+to the clipboard in other text editors. Usage is similar to Vim, with `"` being
25+used to select a register.
26+
27+### User-defined registers
28+
29+Helix allows you to create your own named registers for storing text, for
30+example:
1031
1132- `"ay` - Yank the current selection to register `a`.
1233- `"op` - Paste the text in register `o` after the selection.
1334
14−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:
35+If a register is selected before invoking a change or delete command, the selection will be stored in the register and the action will be carried out:
1536
1637- `"hc` - Store the selection in register `h` and then change it (delete and enter insert mode).
1738- `"md` - Store the selection in register `m` and delete it.
1839
19−### Special Registers
40+### Default registers
41+
42+Commands that use registers, like yank (`y`), use a default register if none is specified.
43+These registers are used as defaults:
2044
2145| Register character | Contains |
2246| --- | --- |
2347| `/` | Last search |
2448| `:` | Last executed command |
2549| `"` | Last yanked text |
26−| `_` | Black hole |
50+| `@` | Last recorded macro |
2751
28−> There is no special register for copying to system clipboard, instead special commands and keybindings are provided. See the [keymap](keymap.md#space-mode) for the specifics.
29−> The black hole register works as a no-op register, meaning no data will be written to / read from it.
52+### Special registers
53+
54+Some registers have special behavior when read from and written to.
55+
56+| Register character | When read | When written |
57+| --- | --- | --- |

4+`YY.0M(.MICRO)`, for example, `22.05` for May of 2022, or in a patch release,
5+`22.05.1`. In these instructions we'll use `<tag>` as a placeholder for the tag
6+being published.
7+
8+* Merge the changelog PR
9+* Add new `<release>` entry in `contrib/Helix.appdata.xml` with release information according to the [AppStream spec](https://www.freedesktop.org/software/appstream/docs/sect-Metadata-Releases.html)
10+* Tag and push
11+ * `git tag -s -m "<tag>" -a <tag> && git push`
12+ * Make sure to switch to master and pull first
13+* Edit the `Cargo.toml` file and change the date in the `version` field to the next planned release
14+ * Due to Cargo having a strict requirement on SemVer with 3 or more version
15+ numbers, a `0` is required in the micro version; however, unless we are
16+ publishing a patch release after a major release, the `.0` is dropped in
17+ the user facing version.
18+ * Releases are planned to happen every two months, so `22.05.0` would change to `22.07.0`
19+ * If we are pushing a patch/bugfix release in the same month as the previous
20+ release, bump the micro version, e.g. `22.07.0` to `22.07.1`

36+## Changelog Curation
37+
38+The changelog is currently created manually by reading through commits in the
39+log since the last release. GitHub's compare view is a nice way to approach
40+this. For example, when creating the 22.07 release notes, this compare link
41+may be used
42+
43+```
44+https://github.com/helix-editor/helix/compare/22.05...master
45+```
46+
47+Either side of the triple-dot may be replaced with an exact revision, so if
48+you wish to incrementally compile the changelog, you can tackle a weeks worth
49+or so, record the revision where you stopped, and use that as a starting point
50+next week:
51+
52+```

55+
56+A work-in-progress commit for a changelog might look like
57+[this example](https://github.com/helix-editor/helix/commit/831adfd4c709ca16b248799bfef19698d5175e55).
58+
59+Not every PR or commit needs a blurb in the changelog. Each release section
60+tends to have a blurb that links to a GitHub comparison between release
61+versions for convenience:
62+
63+> As usual, the following is a summary of each of the changes since the last
64+> release. For the full log, check out the git log.
65+
66+Typically, small changes like dependencies or documentation updates, refactors,
67+or meta changes like GitHub Actions work are left out.

23−* **Extensible**, within reason. Although we want Helix to be productive out-of-the-box, it's not practical or desirable to cram every useful feature and use case into the core editor. The basics should be built-in, but you should be able to extend it with additional functionality as needed. Right now we're thinking Wasm-based plugins.

2424* **Clean code base.** Sometimes other factors (e.g. significant performance gains, important features, correctness, etc.) will trump strict readability, but we nevertheless want to keep the code base straightforward and easy to understand to the extent we can.
