I don't think grep '^[^ ]*:' really counts as writing a parser.
- TheDong 12y agoRunning "make -p" is running a full parser which someone else wrote. Grep is not extracting the targets from a makefile there, it's extracting the targets from an intermediate representation of a makefile.

It quickly becomes an exercise in heuristics and output parsing.
- TheDong 12y agoWe're arguing different things. The comment I replied to, chaosfactors, specifically specified grepping the makefile. You're arguing that you can find all the targets and I never said you can't. I simply said you can't find them all by only grepping the makefile.
