* 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.

-- Converts Vim :help files to HTML. Validates |tag| links and document syntax (parser errors).
|
|
--
|
|
-- NOTE: :helptags checks for duplicate tags, whereas this script checks _links_ (to tags).
|
|
--
|
|
-- USAGE (GENERATE HTML):
|
|
-- 1. Run `make helptags` first; this script depends on vim.fn.taglist().
|
|
-- 2. nvim -V1 -es --clean +"lua require('scripts.gen_help_html').gen('./build/runtime/doc/', 'target/dir/')"
|
|
-- - Read the docstring at gen().
|
|
-- 3. cd target/dir/ && jekyll serve --host 0.0.0.0
|
|
-- 4. Visit http://localhost:4000/…/help.txt.html
|
|
--
|
|
-- USAGE (VALIDATE):
|
|
-- 1. nvim -V1 -es +"lua require('scripts.gen_help_html').validate()"
|
|
-- - validate() is 10x faster than gen(), so it is used in CI.
|
|
--
|
|
-- SELF-TEST MODE:
|
|
-- 1. nvim -V1 -es +"lua require('scripts.gen_help_html')._test()"
|
|
--
|
|
-- NOTES:
|
|
-- * gen() and validate() are the primary entrypoints. validate() only exists because gen() is too
|
|
-- slow (~1 min) to run in per-commit CI.
|
|
-- * visit_node() is the core function used by gen() to traverse the document tree and produce HTML.
|
|
-- * visit_validate() is the core function used by validate().
|
|
-- * Files in `new_layout` will be generated with a "flow" layout instead of preformatted/fixed-width layout.
