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).
