- However, the new ragel-based parser is much faster
than the others, and does not cause 'too many open files' error
that the flex-based parser does (issue #784).
The timings (using src/sampling as being somewhat representative)
$ wclean; wmakeLnInclude -u .; time wmake -s dep
3.4s wmkdepend (ragel) [now default]
5.7s wmkdep (flex)
6.1s cpp -M
- The makeDepend script is for testing purposes only, but could used as
a hook for other dependency generation systems (eg, ninja).
It simply wraps 'cpp -M' in a form that is calling compatible with
wmkdepend.
BUG: wmkdepend parser was missing optional leading space on #include match
STYLE: use -G2 (goto-based) option for wmkdepend state machine
- the machine is compact with few states and lends itself to this
- place wmkdep and dirToString executables under
utilbin/$(WM_ARCH)$(WM_COMPILER).
This helps somewhat when copying rules about, and might help when creating
general rules.
- match comments to names of scripts
- remove comments about using C-shell (not true anymore)
- use 'assert' style syntax in places instead of if/then/fi
- wcleanMachine supports multiple arguments
