------ generating HTML output ---------
|
|
-- Although this can be generalized for outputting any format, since the template
|
|
-- is language-agnostic, this implementation concentrates on HTML.
|
|
-- This does the actual generation of HTML, and provides support functions in the ldoc
|
|
-- table for the template
|
|
--
|
|
-- A fair amount of the complexity comes from operating in two basic modes; first, where
|
|
-- there is a number of modules (classic LuaDoc) or otherwise, where there is only one
|
|
-- module and the index contains the documentation for that module.
|
|
--
|
|
-- Like LuaDoc, LDoc puts similar kinds of documentation files in their own directories.
|
|
-- So module docs go into 'modules/', scripts go into 'scripts/', and so forth. LDoc
|
|
-- generalizes the idea of these project-level categories and in fact custom categories
|
|
-- can be created (refered to as 'kinds' in the code)
