BUGS

• (read-file "nonexisting/file.csv") shows only "could not open file" - should print filename
• error: the expression ("/usr/local/var/mlisp") with message "cannot cast" - should add to what is casting
• better error reporting..for example ls_dir on non existing dir should prind pwd dir

TODO

• add debug support, at least call stack
• add stdtest - to test every functionality
• add parenthesis coloring into linenoise
• multiline editing (kilo editor)
• execute system command should capture stderr
• add some mem stats to benchmark
• create pastebin like web using ml

Code

• documentation
• rename constants in ml_profiler.h
• replace to_string macro in ml.cpp
• add url of source/inspiration to clib/*.cpp
• add instrumentation (time, nr of evals, num of atoms, debug info, debug environment etc)

Language

• support for (), nil, t, in lsp code replace 0 by nil in logicals
• file functions
  • open file
  • read line
  • write line
  • close file
• string functions
  • itok - integer to char, chartoint (better names) - mini printf can be useed for it (%d)
  • compare - needed for sorting, cmp ignore case
  • regexp functions
• date support
  • decode-universal-time
• env functions
  • get-env, set-env; set-env cannot be implemented in stdlib.lsp, because popen is in fact subshell
• format (sprintf)
• setq
• mapcar (funcall, apply)
• syntax highlighting do VS Code
• add hash datatype

Performance

• define is one of most frequent callee, when in scope with very few vars, lookup sequentially
• push_back - repeatedly without reserving size
• range - with for(int i...) and reserving result size can be 3times faster on (range 1 10000)
• mini_sprintf - unnecesary copying between vector and list
• (do, scope ..) repeatedly assign to acc
