[Scons-users] Pass custom arguments to a builder

[delbert dev]

Thanks, is it possible to reuse the same builder again? I now have:

*def my_action(source, target, env):*
*    with zipfile.ZipFile(env['src_file'] , "r") as z:        *
*        z.extractall(env['out_folder'])*
*    print "Extracted : " + env['src_file'] +  " to: " + env['out_folder']*

*# First "envocation"*
*my_cmd_builder = Builder(action=my_action, src_file=gtestOutputFile,
out_folder=outdir)*
*env.Append( BUILDERS = {'MyCmd' : my_cmd_builder } )*
*extract_gtest_cmd = env.MyCmd(["Extract gtest"], os.popen('which
bash').read().strip())*


*# Second "envocation"*
*my_cmd_builder2 = Builder(action=my_action, src_file=gmockOutputFile,
out_folder=outdir)*
*env.Append( BUILDERS = {'MyCmd2' : my_cmd_builder2 } )*
*extract_gmock_cmd = env.MyCmd2(["Extract gmock"], os.popen('which
bash').read().strip())*

*Default(env.Alias('obs', Depends(extract_gtest_cmd,[gmockDownload,
gtestDownload, extract_gmock_cmd])))*

Which is a lot of code to simply call a "function" twice.
