Running command that is dependent on a target

[voidtrance]

Hi, I need to run a command to get its output but the command is dependent on a target. I know that running a command that is dependent on other targets is done with run_target() but that does not allow for the extraction and processing of the command's output.

Is there a way to do what I need? If not, what should I be doing?

Thank you.

You haven't fully explained what you're trying to do.

My guess would be that you want to define a run_target() that

• depends: on the other target
• takes the other target (or its .full_path() possibly) as an argument to the run_target script itself
• your script runs the other target as a subprocess and captures its stdout, then processes and uses it somehow

Here is the flow:

1. custom_target(A) auto-generates a file.
2. run_target('tg', depends: [A]) reads the auto-generated file and outputs a set up lines, each one a library name.
3. I create a library() target based on the lines output bye run_target().
