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
fix https://github.com/neovim/neovim.github.io/issues/297
Problem:
Since eba7b5b646
any opening paren and its leading whitespace " (" are missing in the
generated HTML. Example:
Use ":qa!<Enter>" (careful, all changes are lost!).
^^missing
Position the cursor on a tag (e.g. bars) and hit CTRL-].
^^missing
Solution:
The main recursive loop only processes named children, so check
named_child_count() instead of child_count(). Then anonymous nodes
won't get lost.
