Re: [cdt-dev] command line parsing
|
Since no one cares, I did windows parsing in "cmd" (windows xp) style and unix parsing in "shell" (sh) style.
Examples:
args win unix
/a/b/c d [/a/b/c][d] [/a/b/c][d]
\a\b\c d [\a\b\c][d] [abc][d]
\a\b\c d [\a\b\c][d] [abc][d]
"\a\b\c" [\a\b\c] [\a\b\c]
"a b" [a b] [a b]
'"q"' ['q'] ["q"]
\"a\" ["a"] ["a"] Note: even quotes are passed to spawner - windows spawner removes them, maybe need double escape in this case
Due to API restrictions variable substitution happens _before_ arg splitting, so if project location has spaces it has to be double quoted, i.e.
${project_loc}/path [C:/workspace/project][a/path]
"${project_loc}/path" [C:/worskapce/project a/path]

In CDT we have couple places where we have to parse command line arguments,
make commands args and launch command args.
Pre-5.0 it was very inconsistent and broken (the way quotes, spaces and
other non-trivial case were parsed).
I fixed it 5.0.2 and now it consistent and work as unix "shell" command
line parsing works.
With one problem. Windows. On windows "\" can be used in path names and
therefore cannot be used as escape character.
I forgot about that. So we have a dilemma - do we use 2 different way of
escaping command line on windows and linux, or
use linux one - but with complications on windows (i.e user would have
to use \\ to escape \ or unquote this) or
come up with some 3rd schema which would cover both (which I am not
aware of now).
