- 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

#
|
|
# Description
|
|
# Wrapping for cpp -M with argument/options compatible with
|
|
# <wmake/rules/General/transform> calls of wmkdepend or wmkdep.
|
|
#
|
|
# This is for testing purposes only, but could used as a hook for
|
|
# other dependency generation systems (eg, ninja).
|
|
#
|
|
# Note
|
|
# The order of the calling options is fragile.
|
|
# Handling of '-eENV' not working.
|
|
#
|
|
# Usage
|
|
# makeDepend [-eENV...] [-q] [-oFile] ...
|
|
#
|
|
# -eENV Environment variable path substitutions.
|
|
# -oFile Write output to File.
|
|
# -q Suppress 'No such file' warnings.
