[Scons-users] generate alias list with descriptions

[Brian Fitzgerald]

We do this with this bit of code at the end of the SConstruct, and it's quite possible it was cribbed from the SCons wiki.

First, this bit for setting an option

AddOption('--aliases',
          dest='aliases',
          action='store_true',
          default=False,
          help='List all available build targets')

and then this to actually show the aliases (we have a special call-out for the most important aliases, and if we were clever, we'd not print those twice, but it's not that important):

if GetOption('aliases'):
  print 'Available Build Aliases:'
  print '-----'
  aliases = SCons.Node.Alias.default_ans.keys()
  aliases.sort()
  for x in aliases:
    print x

  print ''
  print 'Build Groups:'
  print '-----'
  for x in filter(lambda x: 'build_' in x, aliases):
    print x
  Exit(0)

Subject: [Scons-users] generate alias list with descriptions

Hello,

I have got a project with a lot of alias definitions. I would like to generate a list (for usability) which creates the alias name and a short description of the alias. How can I do this, is there some build-in support?

Thanks

Phil
