Another thing to like is it has no configuration files. This mattered a great deal in the DOS days because floppies were so slow! But even today, who wants to futz with such? If it needs configuring, I just tweak the code and recompile it. Back in the 80s, I handled configuration by having ME directly patch the ME executable. (This was a trick I learned from the old ADVENT Fortran game.) It was marvelously simple and…

I wrote quite a few DOS programs in the late 80's/early 90's that used ini files appended to the .exe as the configuration. All you had to do was run `copy prog.exe + config.ini program.exe` to build a single file that could be passed around without worrying about either a lost or changeable config file. Your code just needed to read its own exe header to figure out where to offset into it to pull out the ini content…

marginally relevant: I was looking for a terminal text editor for git commits and other similarly simple tasks: my only requirement is that I can save&leave with ^D. Any suggestions?

Simplest I can think of: $ echo 'cat > "$@"' >editor $ chmod +x editor $ GIT_EDITOR=./editor git commit -a stuff [master b2d3915] stuff 1 file changed, 1 insertion(+) You'll need to hit enter before ^D. You can add simple Emacs-like keybindings by changing that into $ echo 'rlwrap cat > "$@"' >editor Or just learn ed: $ GIT_EDITOR=ed git commit --amend -a 256 1c stuff and more stuff . w 271 [master c5092a6] stuff and…

Over at howl.io we've been working on another Lua/moonscript based editor. Incidentally it used scintilla as well until we switched to an in-house engine called aullar. The author wrote a blog post about it: https://howl.io/blog/2016/05/26/introducing-aullar.html

I want to get into that when I get time - an editor with LuaJIT - that should be brilliant.

Reference implementations of medium sized applications are incredibly useful for leveling up as a programmer. While there are many large successful open source applications, many are overwhelming to read and learn from. Having something that outlines the key features and components and which ignores the important but complicated edge cases assists in keeping the attention focused. Now if there are annotation within t…

Do you have anything similar that you would recommend?

No. Parent is correct. Writing code just to show how clever you are, at the expense of others who need to debug and understand it later, is poor taste.

It's pretty weird to see "correct" justified by calling the opposite "poor taste". We're talking about a mismatch between a style of code and certain tools; a better answer is to use tools that work well with the style of code you like.
