Problem: The documentation flow (`gen_vimdoc.py`) has several issues: - it's not very versatile - depends on doxygen - doesn't work well with Lua code as it requires an awkward filter script to convert it into pseudo-C. - The intermediate XML files and filters makes it too much like a rube goldberg machine. Solution: Re-implement the flow using Lua, LPEG and treesitter. - `gen_vimdoc.py` is now replaced with `gen_vimdoc.lua` and replicates a portion of the logic. - `lua2dox.lua` is gone! - No more XML files. - Doxygen is now longer used and instead we now use: - LPEG for comment parsing (see `scripts/luacats_grammar.lua` and `scripts/cdoc_grammar.lua`). - LPEG for C parsing (see `scripts/cdoc_parser.lua`) - Lua patterns for Lua parsing (see `scripts/luacats_parser.lua`). - Treesitter for Markdown parsing (see `scripts/text_utils.lua`). - The generated `runtime/doc/*.mpack` files have been removed. - `scripts/gen_eval_files.lua` now instead uses `scripts/cdoc_parser.lua` directly. - Text wrapping is implemented in `scripts/text_utils.lua` and appears to produce more consistent results (the main contributer to the diff of this change).

--- @brief
|
|
--- The `vim.re` module provides a conventional regex-like syntax for pattern usage
|
|
--- within LPeg |vim.lpeg|.
|
|
---
|
|
--- See https://www.inf.puc-rio.br/~roberto/lpeg/re.html for the original
|
|
--- documentation including regex syntax and more concrete examples.
|
|
|
|
--- Compiles the given {string} and returns an equivalent LPeg pattern. The given string may define
|
|
--- either an expression or a grammar. The optional {defs} table provides extra Lua values to be used
|
|
--- by the pattern.
|
|
--- @param string string
|
|
--- @param defs? table
|
|
--- @return vim.lpeg.Pattern
|
|
function vim.re.compile(string, defs) end
|
|
|
|
--- Searches the given {pattern} in the given {subject}. If it finds a match, returns the index
|
|
--- where this occurrence starts and the index where it ends. Otherwise, returns nil.
|
|
---
|
|
--- An optional numeric argument {init} makes the search starts at that position in the subject
|
|
--- string. As usual in Lua libraries, a negative value counts from the end.
|
|
--- @param subject string
|
|
--- @param pattern vim.lpeg.Pattern|string
|
|
--- @param init? integer
|
|
--- @return integer|nil the index where the occurrence starts, nil if no match
|
|
--- @return integer|nil the index where the occurrence ends, nil if no match

--- Does a global substitution, replacing all occurrences of {pattern} in the given {subject} by
