| # this gist can be used to list all targets, or - more correctly - rules, | |
| # that are defined in a Makefile (and possibly other included Makefiles) | |
| # and is inspired by Jack Kelly's reply to a StackOverflow question: | |
| # | |
| # http://stackoverflow.com/questions/3063507/list-goals-targets-in-gnu-make/3632592#3632592 | |
| # | |
| # I also found this script - http://www.shelldorado.com/scripts/cmds/targets - which does | |
| # something similar using awk, but it extracts targets from the "static" rules from a single | |
| # Makefile, meaning it ignores any included Makefiles, as well as targets from "dynamic" rules | |
| # | |
| # Notes: | |
| # | |
| # (1) the sed expression is "scraping" the make output, and will hence break of the output format ever changes | |
| # (2) the "-r" option excludes the built-in rules, as these are typically not relevant, but isn't required | |
| # (3) implementation as a shell alias or as a Makefile target left as an exercise to the reader :-) | |
| # | |
| # | |
| # in the directory containing your Makefile: | |
| # | |
| make -rpn | sed -n -e '/^$/ { n ; /^[^ .#][^ ]*:/p ; }' | |
| # | |
| # ... or add a touch of color by highlighting the targets in the rules: | |
| # | |
| make -rpn | sed -n -e '/^$/ { n ; /^[^ .#][^ ]*:/p ; }' | egrep --color '^[^ ]*:' | |
| # | |
| # ... or if you prefer just the list of targets, WITHOUT the dependencies: | |
| # | |
| make -rpn | sed -n -e '/^$/ { n ; /^[^ .#][^ ]*:/ { s/:.*$// ; p ; } ; }' | |
Embedding into makefile
#(3) implementation as a shell alias or as a Makefile target left as an exercise to the reader :-)
Thank you for your implementation, it was very helpful as I'm not familiar with sed etc. However, it's a bit tricky in case someone wants to embed this piece into his makefile, so here is the solution to save time:
make -rpn | sed -n -e '/^$/ { n ; /^[^ .#][^ ]*:/ { s/:.*$// ; p ; } ; }'
->
make -rpn | sed -n -e '/^$$/ { n ; /^[^ .#][^ ]*:/ { s/:.*$$// ; p ; } ; }'
Apparently make tries to expand single $ (dollar signs), so they need to be escaped with another $ (dollar sign).
Building on top of that I was able to use it to mark all targets as .PHONY
.PHONY: $(shell sed -n -e '/^$$/ { n ; /^[^ .\#][^ ]*:/ { s/:.*$$// ; p ; } ; }' $(MAKEFILE_LIST))
Works perfectly even for targets mentioned as dependencies.
Here there's a good option
