48−[Installation documentation](https://docs.helix-editor.com/install.html).
34+Packages are available for various distributions (see [Installation docs](https://docs.helix-editor.com/install.html)).
35+
36+If you would like to build from source:
37+
38+```shell
39+git clone https://github.com/helix-editor/helix
40+cd helix
41+cargo install --path helix-term
42+```
43+
44+This will install the `hx` binary to `$HOME/.cargo/bin` and build tree-sitter grammars.
45+If you want to customize your `languages.toml` config,
46+tree-sitter grammars may be manually fetched and built with `hx --grammar fetch` and `hx --grammar build`.
47+
48+Helix also needs its runtime files so make sure to copy/symlink the `runtime/` directory into the
49+config directory (for example `~/.config/helix/runtime` on Linux/macOS, or `%AppData%/helix/runtime` on Windows).
50+
51+| OS | Command |
52+| -------------------- | -------------------------------------------- |
53+| Windows (cmd.exe) | `xcopy /e runtime %AppData%\helix\runtime` |
54+| Windows (PowerShell) | `xcopy /e runtime $Env: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
66+[install the appropriate Language Server](https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers)
67+for a language.

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` |
376−| `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` |

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

170−Without braces to catch the scope of the function, the smallest descendant of

173−to an indent level one too small.
174−
175−To address this case, `@extend` tells helix to "extend" the captured node's span

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

1−//! The `DocumentFormatter` forms the bridge between the raw document text
2−//! and onscreen positioning. It yields the text graphemes as an iterator
3−//! and traverses (part) of the document text. During that traversal it
4−//! handles grapheme detection, softwrapping and annotations.
5−//! It yields `FormattedGrapheme`s and their corresponding visual coordinates.
6−//!
7−//! As both virtual text and softwrapping can insert additional lines into the document
8−//! it is generally not possible to find the start of the previous visual line.
9−//! Instead the `DocumentFormatter` starts at the last "checkpoint" (usually a linebreak)
10−//! called a "block" and the caller must advance it as needed.
