Creator - meta build system for ninja

[Niklas Rosenstein]

Hi folks!

I quickly wanted to share this with you. I've created a small meta build system in Python that generates

ninja build files. Creator is a bit like make in that it doesn't make assumptions on your environment etc.

and gives you all the freedom to specify the actually commands to build your software, but is more

powerful than Make in many aspects.

Creator is based on "Unit Scripts" which are just pure Python code with some additional flavour to get

things running. You can find everything about Creator on the GitHub repository. Also make sure to

check out the Wiki, it contains some extensive information about how Creator works and the built-in

functions available to you in Unit Scripst and during macro evaluation.

Creator on GitHub: https://github.com/NiklasRosenstein/creator

Here's a small example script to build a C program with Creator.

# fooproject.crunit

load('platform', 'p')
load('compiler', 'c')

C['dir.build']  = '$ProjectPath/build'
C['dir.source'] = '$ProjectPath/src'
C['sources'] = '$(wildcard $dir.source/*.cpp)'
C['objects'] = '$(p:obj $(move $sources,$dir.source,$dir.build))'
C['program'] = '$(p:bin $dir.build/main)'

@target
def objects():
  for fin, fout in foreach_split('$sources', '$objects'):
    objects.add('$fin', '$fout', '$c:cpp $c:wall $c:compileonly $< $(c:objout $@)')

@target
def program():
  program.dependencies.append(objects)
  program.add('$objects', '$program', '$c:cpp $(quotesplit $<) $(c:binout $@)')

And this is how you would build the project.

creator ninja -f && ninja

Thanks for checking it out. :)
