Trac Wiki to GitHub Wiki

timmorgan (Tim Morgan) — Wed, 02 Apr 2008 02:05:02 GMT

A rough start of a script to help convert the wiki syntax of Trac pages to GitHub-friendly syntax.

Some TLC is still needed on each output page, but better than doing it all by hand.

Project lives here: github.com/seven1m/trac_wiki_to_github



#!/usr/bin/env ruby

 

TRAC_DB_PATH = 'trac.db'

OUT_PATH = 'wiki'

GITHUB_WIKI_URL = '/seven1m/onebody/wikis/'

 

require 'sqlite3'

 

db = SQLite3::Database.new(TRAC_DB_PATH)

pages = db.execute('select name, text from wiki w2 where version = (select max(version) from wiki where name = w2.name);')

 

pages.each do |title, body|

  File.open(File.join(OUT_PATH, title.gsub(/\s/, '')), 'w') do |file|

    body.gsub!(/\{\{\{([^\n]+?)\}\}\}/, '\1')

    body.gsub!(/\{\{\{(.+?)\}\}\}/m, '\1
')

    body.gsub!(/====\s(.+?)\s====/, 'h4. \1')

    body.gsub!(/===\s(.+?)\s===/, 'h3. \1')

    body.gsub!(/==\s(.+?)\s==/, 'h2. \1')

    body.gsub!(/=\s(.+?)\s=[\s\n]*/, '')

    body.gsub!(/\[(http[^\s\[\]]+)\s([^\[\]]+)\]/, '"\2":\1')

    body.gsub!(/\[([^\s]+)\s(.+)\]/, '"\2":' + GITHUB_WIKI_URL + '\1')

    body.gsub!(/([^"\/\!])(([A-Z][a-z0-9]+){2,})/, '\1[[\2]]')

    body.gsub!(/\!(([A-Z][a-z0-9]+){2,})/, '\1')

    body.gsub!(/'''(.+)'''/, '*\1*')

    body.gsub!(/''(.+)''/, '_\1_')

    body.gsub!(/^\s\*/, '*')

    body.gsub!(/^\s\d\./, '#')

    file.write(body)

  end

end



Trac Subversion Repository scraper
deanh (Dean Holdren) — Sat, 27 Jan 2007 02:25:10 GMT
Ruby script to pull code from a Trac repo browser.  Useful if you are behind a firewall/proxy and the server has no http access to the subversion repo. (I'm sure its not the prettiest/best/rubiest way to do it, but it worked for me)





#!/usr/bin/env ruby



require 'rubygems'

require 'hpricot'

require 'open-uri'





#a Trac repo scraper. pass the url to scrape (the root of a repo)

#  and optionally the local path to write to.  defaults to .



class TracRepoScraper



  def initialize(trac_url, local_path='.')

    @trac_url = trac_url



    trac_url =~ /(http:\/\/.*?)\//

    @trac_server = $1

    @local_path =  local_path

  end



  def getallfiles(url,cur_localpath)

    if cur_localpath != '.'

      Dir.mkdir(cur_localpath)

    end

    doc = Hpricot(open(url).read)

    doc.search("//tbody//tr//td//a[@class='file']").each do |file_anchor|

      #get the file as curpath+/file_name



      #following gives us absolute path (excluding domain)

      actual_file_url = @trac_server + file_anchor['href']+'?format=raw'

      #temp

      puts "Saving #{actual_file_url} to #{cur_localpath}/#{file_anchor.inner_html}"

      #read the file and write to a file in the correct directory

      File.open(cur_localpath+"/"+file_anchor.inner_html, 'w') do |f|

        remote_file = open(actual_file_url)

        remote_file.each { |line|

          f.puts(line)

        }

      end

    end



    doc.search("//tbody//tr//td//a[@class='dir']").each do |dir_anchor|

      #go into the directory

      dir_url = @trac_server + dir_anchor['href']

      puts "*** stepping into #{dir_url}"

      #dir_anchor.inner_html is the name of the subdirectory (relative)

      getallfiles(dir_url, cur_localpath+"/"+dir_anchor.inner_html)

    end

  end



  def start

    getallfiles(@trac_url, @local_path)

  end

end





#### main



trac_url = ARGV[0]

localpath = '.'

if ARGV[1]

  if !ARGV[1].strip.empty?

    localpath = ARGV[1].strip

  end

end



TracRepoScraper.new(trac_url, localpath).start




Trac installation on its own subdomain
chipx86 (Christian Hammond) — Thu, 29 Dec 2005 15:59:04 GMT
Most installation documents of Trac show how to install to a directory in the main site's domain. For installation into a subdomain, the Trac data and CGI script should be installed into trac.domain.com/htdocs/trac/, with the following in the Apache config file:







  AllowOverride None

  Options ExecCGI

  AddHandler cgi-script .cgi

  Order allow,deny

  Allow from all







  ServerName trac.domain.com

  DocumentRoot /path/to/trac.domain.com/htdocs/



  RewriteEngine On

  RewriteCond %{REQUEST_URI} !^/cgi-bin/

  RewriteCond %{REQUEST_URI} !^/trac/

  RewriteRule ^/(.*) /trac/trac.cgi/$1 [L]



  

    SetEnv TRAC_ENV "/var/lib/trac/projname">
