Is there any progress on this in the meantime? I even encounter a few seconds wait time with very short makefiles which need to run commands for variables. Can command running be disabled to speedup tab completion at the cost of correctnes?

I think there are no efforts on this for now.
with very short makefiles which need to run commands for variables.
In the original report, the time of sed
(10 secs) seems to be longer than that of make
(4 secs). In the case that commands are run for variables, I guess the time of make
should be dominant. What is the result of the following command in the directory?
$ time make -npq | wc
If this explains the most part of the delay you observe, I think it's difficult to improve the response because there is no way to disable only $(shell slow-command)
in Makefile unless GNU make supports the feature. However, if we give up completions of all the targets that includes variables or wildcards (such as $(OBJDIR)/file
or %.o
) and also give up tracking include
s, we may just run sed -n 's/^[[:space:]]*\([^:]*[^[:space:]]\)[[:space:]]*:\([^=].*\)\{0,1\}$/\1/p' Makefile
to extract target names. Or another way might be to use timeout
command to set a timeout for the call of make -npq
, and to fall back to the above simple sed
on the timeout.
