punkshell - an alternative Tcl Shell

BSD license

2023-08 Note: this is alpha level software and still highly experimental.

Features

• default ansi color output - toggle with 'colour on' and 'colour off'
• experimental functional language features. (will not be performant until more work is done on script compilation) e.g
  var_pipe_output.= var_list.= list a b c |> string toupper
• easy execution of externals commands with return of stdout, stderr and the exitcode of the process
  • run <comand> ... (return exitcode of process - and allows process writes to stderr/stdout to appear in console as they occur)
  • runout <command> ... (return stdout of process - no output until completion)
  • runerr <command> ... (return stderr of process - no output until completion)
  • runx <command> ... (return a dict of stdout stderr exitcode - no output until completion)

very unripe parts:

• commandline options - in need of urgent work to document and lock down specifics - in particular: punkshell somescript.tcl needs a fix to emit errors.
• shellfilter - api is clumsy
• scriptlib - will likely be reorganised/pruned significantly
