Painless inserting of nicely highlighted code block to my blog

If u happen to like the way i display code blocks in this blog & have read my previous post abt how i have given this blog a face-lifting, here are some extra steps i've taken to conveniently allow me to:

# 1. edit whatever code i want to display in vim

# 2. use a user-defined command (while still in vim) :Xc to process the entire (or selected lines) of the current buffer to yield nicely-highlighted code block & load it to the X11 clipboard (using xclip)

# 3. use middle mouse click (hehe, i'm using thinkpad, anyway, this can be done by doing left & right click together on mouse) to paste it to whereever i like (eg. the textarea i'm typing in right now)

Enough said, let's get into action:

# S1. Installing the required packages:

pacman -S xclip

# S2. Inserting the user-defined command :Xc to ~/.vimrc

1 2 3 4 5

func! Xclip() range execute ":!~/bin/code2html.rb " . bufname('%') . " " . a:firstline . ":" . a:lastline . " | xclip" endfu com! -range=% -nargs=0 Xc <line1>,<line2>call Xclip()

# S3. Revising the existing ~/bin/code2html.rb to accept extra args

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

#!/usr/bin/env ruby require 'rubygems' require 'coderay' require 'tempfile' file = ARGV[0] range = ARGV[1].split(':').map(&:to_i).map(&:pred) rescue nil if range basename = Time.now.to_i.to_s extension = file[/\/.*?.(\.[^\.]*?)$/,1] Tempfile.open(extension ? [basename, extension] : basename) do |fh| fh.write(File.readlines(file)[range[0] .. range[-1]].join) file = fh.path end end puts %|#{coderay.scan_file(file).html(:line_numbers => :table)}|. gsub('coderay','coderay').split('<pre').map{|s| !s.include?('</pre>') ? s.gsub("\n",'').squeeze(' ') : ( parts = s.split('</pre>') [parts[0], parts[1].gsub("\n",'').squeeze(' ')].join('</pre>') ) }.join('<pre')

To try out, restart ur vim to edit any file, to convert the entire file, run the following command in vim:

:Xc

Alternatively, if u want to convert the selected lines (in visual mode, using Shift-v to select the specific lines):

:'<,'>Xc

And to do the pasting, just do middle (mouse) click on any textarea u are working on.
