-- todo: folding and comments
-- todo: runners (awaiting global script setup)
-- todo: dark theme
-- Already for quite a while lexing in ConTeXt is kind of standardized and the way
-- the format evolved also relates to how I see the source. We started with lexing
-- beginning of 1990 with texedit/wdt in Modula2 and went via perltk (texwork),
-- Scite (native), Scite (lpeg) as well as different stages in verbatim. So, as
-- github uses VSCODE I decided to convert the couple of base lexers to the format
-- that this editor likes. It's all about habits and consistency, not about tons of
-- fancy features that I don't need and would not use anyway.
--
-- I use a lua script to generate the lexer definitions simply because that way the
-- update will be in sync with the updates in the context distribution.
--
-- code.exe --extensions-dir e:\vscode\extensions --install-extension context
--
-- In the end all these systems look alike so again we we have these token onto
-- styling mappings. We even have embedded lexers. Actually, when reading the
-- explanations it has become internally more close to what scintilla does with
-- tokens and numbers related to it but then mapped back onto css.
--
-- Multiline lexing is a pain here, so I just assume that stuff belonging together is
-- on one line (like keys to simple values). I'm not in the mood for ugly multistep
-- parsing now. Here the lpeg lexers win.
--
-- We can optimize these expressions if needed but it all looks fast enough. Anyway,
-- we do start from the already old lexers that we use in SciTe. The lexing as well
-- as use of colors is kind of consistent and standardized in context and I don't
-- want to change it. The number of colors is not that large and (at least to me) it
-- looks less extreme. We also use a gray background because over time we figured
-- out that this works best (1) for long sessions, and (2) for colors. We have quite
-- some embedding so that is another reason for consistency.
--
-- I do remember generating plist files many years ago but stopped doing that
-- because I never could check them in practice. We're now kind of back to that. The
-- reason for using a lua script to generate the json file is that it is easier to
-- keep in sync with context and also because then a user can just generate the
-- extension her/himself.
--
-- There are nice examples of lexer definitions in the vc extensions path. My regexp
-- experiences are somewhat rusted and I don't really have intentions to spend too
-- much time on them. Compared to the lpeg lexers the regexp based ones are often
-- more compact. It's just a different concept. Anyway, I might improve things after
-- I've read more of the specs (it seems like the regexp engine is the one from ruby).
-- We normally use a light gray background with rather dark colors which at least
-- for us is less tiresome. The problem with dark backgrounds is that one needs to
-- use light colors from pastel palettes. I need to figure out a mapping that works
-- for a dark background so that optionally one can install without color theme.
-- It is possible to define tasks and even relate them to languages but for some reason
-- it can not be done global but per workspace which makes using vscode no option for
-- me (too many different folders with source code, documentation etc). It's kind of
-- strange because simple runners are provided by many editors. I don't want to program
-- a lot to get such simple things done so, awaiting global tasks I stick to using the
-- terminal. But we're prepared.
-- Another showstopper is the fact that we cannot disable utf8 for languages (like pdf,
-- which is just bytes). I couldn't figure out how to set it in the extension.
