Test code to split up mutt_extract_token()

Build

• It expects NeoMutt to be built in ../neo
  • make
  • make test

Notes

• Eliminate dependence on MuttWindow
  1. Duplicate environment
  2. Set COLUMNS
  3. Pass to exec

Won't work. We'd need to pass the dupe environment to the token function. exec() needs to happen outside of token function.

• Move filter.c to libmutt?

  • Factor out environment
  • Factor out EXECSHELL
  • Do we need both fd and FILE versions?

• Eliminate myvar?

  • Fold myvar support into libconfig?
  • Handle is still held by NeoMutt

Option Behaviour and Callers

• MUTT_TOKEN_BACKTICK_VARS - Expand variables within backticks

  • Contents are executed in a shell (EXECSHELL)
  • parse_set()

• MUTT_TOKEN_COMMENT - Don't reap comments

  • pattern.eat_regex()
  • pattern.eat_query()
  • pattern.eat_date()

• MUTT_TOKEN_CONDENSE - ^(char) to control chars (macros)

  • mutt_parse_push()
  • mutt_parse_macro()

I think this should be happening after token, in the caller.

• MUTT_TOKEN_EQUAL - Treat '=' as a special

  • parse_set()
  • parse_setenv()

• MUTT_TOKEN_NOSHELL - Don't expand environment variables

  • Recursive call to mutt_extract_token()

• MUTT_TOKEN_PATTERN - ~%=!| are terms (for patterns)

  • pattern.eat_regex()
  • pattern.eat_query()
  • pattern.eat_date()

These are all non-whitespace. Do we need special cases for them?

• MUTT_TOKEN_QUESTION - Treat ? as a special
  • parse_set()

For ':set ?var' or ':set var?' Can't this be dealt with by the caller?

• MUTT_TOKEN_QUOTE - Don't interpret quotes

  • parse_alias()
  • parse_my_hdr()

• MUTT_TOKEN_SEMICOLON - Don't treat ; as special

  • parse_alias()

• MUTT_TOKEN_SPACE - Don't treat whitespace as a term

  • parse_alias()
  • parse_ifdef()
  • parse_my_hdr()
  • mutt_parse_hook()

• MUTT_TOKEN_NO_FLAGS - Default behaviour
