Problem:
- Since #28678, pre-formatted text in the online documentation do not
render whitespaces correctly: should be pre-like text, but shown like
normal paragraph (see #28754).
- Code blocks with long lines should not be wrapped (e.g. see
|dev-vimpatch-list-management|).
Solution:
- Use `white-space: pre-wrap`. Compared to `white-space: pre`, this
option will make long lines including a very long URL wrapped.
This properly fixes#28754 and #28678.
- Use horizontal scrollbar for the code blocks that are horizontally too
long, instead of wrapping text. This will make the code easy to read
while the pre-text block not interfering with the navigation bar.
Problem:
On the page: https://neovim.io/doc/user/dev_vimpatch.html
The links extend beyond the container and thus end up behind the navigation to the right.
Solution:
Add these lines to get_help_html.lua:
white-space: normal;
word-wrap: break-word;
- Added `@inlinedoc` so single use Lua types can be inlined into the
functions docs. E.g.
```lua
--- @class myopts
--- @inlinedoc
---
--- Documentation for some field
--- @field somefield integer
--- @param opts myOpts
function foo(opts)
end
```
Will be rendered as
```
foo(opts)
Parameters:
- {opts} (table) Object with the fields:
- somefield (integer) Documentation
for some field
```
- Marked many classes with with `@nodoc` or `(private)`.
We can eventually introduce these when we want to.
- Add type annotations, fix most of the type warnings.
- Fix a minor bug on `spell_ignore_files`: nil error when an invalid
spelling is found but the file is not ignored.
Summary: Separate the lint job (`make lintdoc`) to validate runtime/doc,
it is no longer as a part of functionaltest (help_spec).
Build (cmake) and CI:
- `make lintdoc`: validate vimdoc files and test-generate HTML docs.
CI will run this as a part of the "docs" workflow.
- `scripts/lintdoc.lua` is added as an entry point (executable script)
for validating vimdoc files.
scripts/gen_help_html.lua:
- Move the tests for validating docs and generating HTMLs from
`help_spec.lua` to `gen_help_html`. Added:
- `gen_help_html.run_validate()`.
- `gen_help_html.test_gen()`.
- Do not hard-code `help_dir` to `build/runtime/doc`, but resolve from
`$VIMRUNTIME`. Therefore, the `make lintdoc` job will check doc files
on `./runtime/doc`, not on `./build/runtime/doc`.
- Add type annotations for gen_help_html.
There is no reason for this file to be in project root, which is crowded
as is. This also fits nicely part of the ongoing work towards gathering
as much of the documentation as possible into one place.
Problem: Wiki contents are not discoverable and hard to maintain.
Solution: Move FAQ to runtime docs.

Problem:
We don't enable stylua for many Lua scripts. Automating code-style is an
important tool for reducing time spent on accidental (non-essential)
complexity.
Solution:
- Enable lintlua for `scripts/` directory.
- Specify `call_parentheses = "Input"`, we should allow kwargs-style
function invocations.
Problem:
In the generated docs HTML there is too much whitespace before/after `<pre>`
blocks.
- In the old layout (fixed-width), all text in `.old-help-para` is formatted as
`white-space:pre`.
- In the new layout, when `<pre>` is at the end of a `<div>`, the margins of
both are redundant, causing too much space.
Solution:
- In the old layout, always remove `<pre>` margin.
- In the new layout, disable `<pre>` margin if it is the last child.
Enforce consistent terminology (defined in
`gen_help_html.lua:spell_dict`) for common misspellings.
This does not spellcheck English in general (perhaps a future TODO,
though it may be noisy).
- quickstart
- mark lsp.txt as `new_layout`
- remove lsp-handler documentation for notifications: they don't have
handlers because they don't have server responses.
Problem:
Selecting a search result from the Algolia Docsearch widget does not
navigate to a page anchor. The docs HTML provides `<a name=…>` anchors
_near_ the `<h1>`/`<h2>`/… headings, but Algolia Docsearch expects the
anchors to be _defined on_ the headings. That's also "semantically"
nicer. https://docsearch.algolia.com/docs/manage-your-crawls/
Solution:
Set `id` on the heading element instead of placing `<a name=…>` nearby.

* feat(lua): vim.tbl_contains supports general tables and predicates
Problem: `vim.tbl_contains` only works for list-like tables (integer
keys without gaps) and primitive values (in particular, not for nested
tables).
Solution: Rename `vim.tbl_contains` to `vim.list_contains` and add new
`vim.tbl_contains` that works for general tables and optionally allows
`value` to be a predicate function that is checked for every key.
Use `white-space: pre-wrap` to preserve white space as per `pre`, but to
allow line wrapping if the display runs out of horizontal space.
This prevents lines overflowing their box, and causing horizontal
scrolling across the entire page on small screens.
This `pre-wrap` technique is used by GitHub to format code for mobile.
See https://developer.mozilla.org/en-US/docs/Web/CSS/white-space#pre-wrap
Problem:
`gen_help_html.lua` does not properly handle tab characters after
"concealed" text (tags, taglinks, codespans). This causes misaligned
layout in "old" (preformatted) docs.
For text like `*tag*`, |tag_link|, and `code_span`, Vim hides the "*",
"|", "`" characters, but Vim still counts those characters for "virtual
column" when a tab character follows it. So if you have a tag of say
6 characters long, those two concealed character would lead to the tab
character after it start at column 8. gen_help_html.lua doesn't account
for that which leads to formatting flaws in the generated output.
Solution:
Add two spaces after concealed nodes that are followed by a tab char.
Problem:
The generated ToC (table of contents) uses anchors derived from the
heading title, e.g. the "Global Plugins" heading yields:
https://neovim.io/doc/user/usr_05.html#_global-plugins-
so if the heading title changes, then the old URL (anchor) is broken.
Solution:
:help tags change less often than heading titles, so if a heading
contains a *tag*, use that as its anchor name instead. Example:
https://neovim.io/doc/user/usr_05.html#standard-plugin
- Improve generated HTML by updating parser which includes fixes for
single "'" and single "|":
https://github.com/neovim/tree-sitter-vimdoc/pull/31
- Updated parser also fixes the conceal issue for "help" highlight
queries https://github.com/neovim/tree-sitter-vimdoc/issues/23 by
NOT including whitespace in nodes.
- But this means we need to restore the getws() function which scrapes
leading whitespace from the original input (buffer).
Problem:
- Docs HTML: "foo ~" headings (column_heading) are not aligned with
their table columns/contents because the leading whitespace is not
emitted.
- taglinks starting with hyphen like |-x| were not recognized.
- keycodes like `<foo>` and `CTRL-x` were not recognized.
- ToC is not scrollable.
Solution:
- Add ws() to the column_heading case.
- Update help parser to latest version
- supports `keycode`
- fixes for taglink, argument
- Update .toc CSS. https://github.com/neovim/neovim.github.io/issues/297
