PLANNED

Parser

Parser engine (src/intrpr/eng.py)

  1. [DONE] Rewrite the parser to return an AST.
  2. Implement globbing.

Core interpreter

Interpreter engine (src/intrpr/eng.py)

  1. [IRRELEVANT] [DROPPED] Use temporary files to overcome the restriction in size of io.StringIO buffers.
  2. [DONE] Rewrite the engine to fit the rewritten parser.
    • [DONE] Right now, I've made the parser return BinCmd, which is not going to be very good for knowing if the STDOUT needs to output to a TTY or not. So, instead the design needs to be changed in such a way that a CmdExpr node contains an array of operators and an array of SimpCmd nodes. That way, the SimpCmd nodes in the middle can see what operator is next to it.
  3. [DONE] Implement aliases.
  4. Improve aliases. Right now, it's very basic. You can alias only commands, not commands and options or arguments or flags.

General utils and command API (src/utils/gen.py)

  1. [DONE] Implement kbhit(). See the issues file for more information.
  2. Implement tab completion.

Command modules

ls (src/bin/ls.py)

  1. [DONE] Item type differentiation: Output different symbols for different file types, as well as colour the output consistently.
  2. [DONE] Number of inode links: Implement display of number of inode links. Use stat.st_nlink.

pl (src/bin/pl.py)

  1. [DONE] Add process filtering.
