= Adblock2Privoxy = ''Convert adblock config files to privoxy format'' == Introduction == !AdBlock Plus browser plugin has great block lists provided by big community, but it is client software and cannot work on a server as a proxy. Privoxy proxy has good potential to block ads at server side, but it experiences acute shortage of updated block lists. This software converts adblock lists to privoxy config files format. Almost all adblock features are supported including * block/unblock requests (on privoxy) * all syntax features are supported except for regex templates matching host name * hide/unhide page elements (via CSS) * all syntax features are supported * all block request options except for outdated ones: * Supported: script, image, stylesheet, object, xmlhttprequest, object-subrequest, subdocument,document, elemhide, other, popup, third-party, domain=..., match-case, donottrack * Unsupported: collapse, background, xbl, ping and dtd Tested with privoxy version 3.0.21. Element blocking feature requires a webserver to serve CSS files. See Nginx and Apache config examples provided. == Usage == {{{ adblock2privoxy [OPTION...] [URL...] -v --version show version number -p PATH --privoxyDir=PATH privoxy config output path (required) -w PATH --webDir=PATH css files output path (optional, privoxyDir is used by default) -t PATH --taskFile=PATH path to task file containing urls to process -f --forced run even if no sources are expired }}} Example of first run: {{{ adblock2privoxy -p /etc/privoxy -w /var/www/privoxy -t my_ab2b.task https://easylist-downloads.adblockplus.org/easylist.txt https://easylist-downloads.adblockplus.org/advblock.txt my_custom.txt }}} Example of subsequent runs: {{{ adblock2privoxy -p /etc/privoxy -w /var/www/privoxy -t my_ab2b.task }}} The app generates following files * privoxyDir: * ab2p.system.action * ab2p.action * ab2p.system.filter * ab2p.filter * webDir: * ab2p.common.css * ab2p.css * [lot of directories for first level domain names] * taskFile: * special file containing execution details. It can be reused to update privoxy config from same sources. == How to apply results == 1) Install privoxy. Optionally setup it as transparent proxy 2) Change privoxy config file: Add following lines {{{ actionsfile ab2p.system.action actionsfile ab2p.action filterfile ab2p.system.filter filterfile ab2p.filter }}} 3) Install nginx or apache webserver Nginx config example: {{{ server { listen 80; #ab2p css domain name (optional) server_name privoxy.zubr.me; #root = webDir parameter value root /var/www/privoxy; location ~ ^/[^/.]+\..+/ab2p.css$ { # first reverse domain names order rewrite ^/([^/]*?)\.([^/.]+)(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?/ab2p.css$ /$9/$8/$7/$6/$5/$4/$3/$2/$1/ab2p.css last; } location ~ (^.*/+)[^/]+/+ab2p.css { # then try to get CSS for current domain # if it is unavailable - get CSS for parent domain try_files $uri $1ab2p.css; } } }}} Apache config example: {{{ #ab2p css domain name (optional) ServerName www.example.com #root = webDir parameter value DocumentRoot /var/www/privoxy RewriteEngine on # first reverse domain names order RewriteRule ^/([^/]*?)\.([^/.]+)(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?/ab2p.css$ /$9/$8/$7/$6/$5/$4/$3/$2/$1/ab2p.css [N] # then try to get CSS for current domain # if it is unavailable - get CSS for parent domain RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule (^.*/+)[^/]+/+ab2p.css$ $1ab2p.css [N] }}} 4) Find out files to use. Some download locations * !EasyList: https://easylist.adblockplus.org/en/ * Russian AD list: https://code.google.com/p/ruadlist/ 5) Run adblock2privoxy providing privoxy dir, web dir and adblock input file urls 6) Restart privoxy and apache to load updated configs Clone repository from ​http://projects.zubr.me/adblock2privoxy.git
