Syntax highlighting with vim & Ruby

ntk () — Fri, 24 Nov 2006 16:24:09 GMT

From: http://www.ruby-forum.com/topic/64262

This snippet will convert source code files to syntax-colored html files.
usage: vim-syntax-highlighting.rb src.rb src.html





require 'tempfile'



$VERBOSE=nil

STDERR.reopen(Tempfile::new($$)) unless STDIN.tty?



fin, fout, _ = ARGV

fin = ((fin.nil? or fin == '-') ? STDIN : open(fin))

fout = ((fout.nil? or fout == '-') ? STDOUT : open(fout,'w+'))

Rails and Vim

jlong (John W. Long) — Sat, 29 Jul 2006 03:00:20 GMT

A simple command for opening related Rails project files in Vim:



#!/usr/bin/env ruby



if ARGV.empty?

  puts "usage: #{File.basename($0)} string" 

  puts "  Scans related Rails directories for " + 

         "files begining with string " 

  puts "  and opens them in vi." 

  exit

end



files = []

ignore = [/CVS$/]



# Find models or controllers that match args

ARGV.each do |arg|

  models = Dir["app/models/#{arg}*"]

  controllers = Dir["app/controllers/#{arg}*"]

  files += models + controllers

end



# Remove duplicates

files.sort!.uniq!



# Add unit tests for models

files.grep(%r{app/models/(.*?).rb}) do

  tests = Dir["test/unit/#{$1}_test.rb"]

  files += tests

end



# Add views and functional tests for controllers

files.grep(%r{app/controllers/(.*?)_controller.rb}) do

  views = Dir["app/views/#{$1}/*"]

  tests = Dir["test/functional/#{$1}_controller_test.rb"]

  files += views + tests

end



# Add views and fixtures for mailers

files.grep(%r{app/models/(.*?_mailer).rb}) do

  views = Dir["app/views/#{$1}/*"]

  fixtures = Dir["test/fixtures/#{$1}/*"]

  files += views + fixtures

end



# Again remove duplicates

files.sort!.uniq!



# Remove files that match ignore list

files.delete_if do |filename|

  result = false

  ignore.each do |i|

    if filename =~ i

      result = true

      break

    end

  end

  result

end



system "vi -o #{files.join(' ')}"

Drop it in a file called "edit" in your path and you can open related rails files with a few key strokes:



# open AccountController and related tests and views:

edit account_c



# open AccountMailer and related tests, views, and fixtures:

edit account_m



# open everything related to accounts:

edit account

Basic ant script with vim & jikes

mikewilsonuk (Mike Wilson) — Fri, 19 May 2006 19:39:56 GMT

Apache ant build XML. This will use jikes in place of javac. Any compiler error output is formatted so that vim can parse it.

ant is a modern alternative to make. The build script is an XML file. It works particularly well with java. Download it for free from the Apache ant site. Most people find ant a lot nicer to live with than make.
