Been working on an improved indentexpr for vim-racket; if anyone is interesting in helping me dogfood it, please LMK and I'll clean it up and push a branch. Vim 9+ required.
Current improvements: handles {} and #<<herestrings correctly; indents (foo\nbar) correctly (b under f instead of under o ). Current issues: speed when reindenting whole files (small functions have been fine so far). I've one last "trick" to port from the C source for get_lisp_indent to try to speed things up which effectively uses the buffer contents like a cache; this should solve the speed problems.
