SCons Builder for Ragel

Here's a SCons builder for the Ragel State Machine Compiler, based on the one for SWIG included in the SCons distribution.

#            tastes like -*- python -*-

"""Tool-specific initialisation for ragel."""

import SCons.Util
import SCons.Tool
import SCons.Action

def generate(env):

    c_file, cxx_file = SCons.Tool.createCFileBuilders(env)
    c_file.suffix['.rl'] = '.c'

    c_file.add_action('.rl', SCons.Action.Action('$RAGELCOM', '$RAGELCOMSTR'))

    env['RAGEL'] = 'ragel'
    env['RAGELFLAGS'] = SCons.Util.CLVar('')

    env['RLCODEGEN'] = 'rlcodegen'
    env['RLCODEGENFLAGS'] = SCons.Util.CLVar('')

    env['RAGELCOM'] = \
        '$RAGEL $RAGELFLAGS $SOURCE | $RLCODEGEN $RLCODEGENFLAGS -o $TARGET'

def exists(env):
    return env.Detect(['ragel', 'rlcodegen'])

How to patch and rebuild a RPM package

Here's a nice tutorial on how to make a patch to a program distributed as a SRPM file. I would also recommend installing ccache and maybe distcc as finding and fixing bugs in a RPM build usually involves compiling the same source files over and over again.

Another Stevey Blog Rant About Emacs

Here. It's quite long and complicated. I wish I had time to write that much stuff about Emacs. Anyway, some choice quotes about whether you should learn Emacs Lisp:

"First, recognize that Emacs Lisp isn't going anywhere. Emacs is not going to magically become programmable in Python or Ruby or JavaScript or Perl overnight ... [Emacs Lisp] will never be obsolete knowledge. You might as well start learning it now, and reap the benefits now."

On Lisp syntax:

"If you do it enough, eventually you'll enjoy programming in Emacs-Lisp, no matter how much you hate it initially ... you'll initially dislike Emacs-Lisp's syntax; it's virtually guaranteed. Fortunately, it doesn't really have much in the way of syntax; almost everything follows the exact same s-expression form. So you should get past the syntax pretty quickly, and in a few weeks you'll start liking it just fine.

I've done some bits and pieces of Emacs Lisp programming over the years and it is quite seductive, for lack of a better word. I think that's the nature of functional programming though once you really get in to it.
