From 7831a3f58d25e111b160c8581004a70a10fff070 Mon Sep 17 00:00:00 2001 From: Emmanuel Lepage Vallee Date: Sun, 24 Nov 2019 03:56:19 -0500 Subject: [PATCH] doc: Re-implement tag parsing in the config. So, now ldoc is implemented within ldoc, great! This is done to allow new custom tags to have the same power and expressivness as built in ones. This way we can express signals and theme variables correctly. --- docs/config.ld | 233 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 233 insertions(+) diff --git a/docs/config.ld b/docs/config.ld index 76508b46e..182a4c281 100644 --- a/docs/config.ld +++ b/docs/config.ld @@ -93,6 +93,145 @@ new_type("filterfunction", "List filters", false) -- Extra client properties available only in awful.rules/spawn constructs new_type("clientruleproperty", "Extra properties available in awful.rules and awful.spawn", false, "Type") +-- Simulate the default "params" parser format, except the optional "[]" section +-- needs a space. +local function parse_custom_tags(text, params) + text = text:gmatch("[ ]*(.*)$")() + local raw_extra = "" + + if text:sub(1,1) == '[' then + local count = 1 + + -- Find the matching ']' + for i=2, text:len() do + local char = text:sub(i,i) + + if char == '[' then + count = count + 1 + elseif char == ']' then + count = count - 1 + end + + raw_extra = raw_extra..char + + if count == 0 then + text = text:sub(i+2) + break + end + end + end + + -- Split the remaining text into words. + local words, values, description = {}, {}, {} + + for word in text:gmatch("[^ \n\r]*") do + if word ~= "" then + words[#words+1] = word + end + end + + for idx, word in ipairs(words) do + if idx <= #params then + local name = params[idx].name + values[name] = { + name = name, + title = params[idx].title or name, + value = word + } + else + description[#description+1] = word + values.description = values.description and + values.description.."
