Details:
Hello,
I developed a new feature that import a makefile.
It is similar to include feature except that if the imported makefile is in a
different directory all rules using relative path remains relative to the
imported makefile and not the parent one.
To achieve this, make does a chdir in the imported makefile directory before
reading it, prefix relative targets and prerequisites with the path of the
imported makefile and does a chdir before executing commands.
With import feature it is possible to do things like this:
$ path/to/a.mk:
relative_target : relative_prerequisite /prerequisite
cmd1
/target : relative_prerequisite /prerequisite
cmd2
$ b.mk
import path/to/a.mk
> make -f b.mk
In this example make will create the following rules:
path/to/relative_target : path/to/relative_prerequisite /prerequisite
cmd1
/target : path/to/relative_prerequisite /prerequisite
cmd2
cmd1 and cmd2 are executed in path/to/ directory.
This feature is on my repo:
https://github.com/ydaveluy/make/tree/feature_import
Can you give me a feedback ?
I can write some unit test and improve the code if needed.
Yannick
