Testing of the LATEX plugin. It seems superficially to work. Adding this wiki markup:

<pre> <math>\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}</math> </pre>

gives this:

<math>\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}</math>

However this

<pre><math>\frac{\partial \left\langle E \right\rangle}{\partial T} = \frac{\partial}{\partial T} \left\{ \frac{1}{Z} \int E \exp{-\beta E} \mathrm{d}E \right\}</math></pre>

gives <pre> Failed to parse (Missing <code>texvc</code> executable. Please see math/README to configure.): </pre>

<math>\frac{\partial \left\langle E \right\rangle}{\partial T} = \frac{\partial}{\partial T} \left\{ \frac{1}{Z} \int E \exp{-\beta E} \mathrm{d}E \right\}</math>

There are two instances of the texvc executable present in the wiki

./math/texvc

'''PARSOID translation layer runtime installation and integration with mediawiki'''

The VisualEditor relies on a stand-alone parsoid service to bi-directionally translate between wikitext and RTF.

The parsoid server is written in nodejs and lives on the wiki in /var/www/html/wiki/parsoid

Install the appropriate EPEL repo which allows you to install nodejs and npm

pull parsoid from git

Run the installer from the parsoid directory with: npm install

The resultant compiled service is run with:

node <parsoid dir>/api/server.js

or ...

cd <parsoid dir>
npm start

Simple stop script called with /etc/init.d/parsoid stop

#!/bin/bash
pkill -9 node

Simple start script called from /etc/init.d/parsoid start

#!/bin/bash
cd /var/lib/parsoid/
export INTERFACE=127.0.0.1
export PORT=8000
/usr/bin/node api/server.js &

I have written a basic startup script /etc/init.d/parsoid

!/bin/bash
chkconfig: 345 99 01
# description: Quest Foglight 5 Agents.
# Source function library
. /etc/init.d/functions
STARTPATH="/var/www/html/wiki/parsoid/api/start_parsoid"
STOPPATH="/var/www/html/wiki/parsoid/api/stop_parsoid"
USERNAME="apache"
case "$1" in
'start')
if [ -x ${STARTPATH} ]; then
daemon --user ${USERNAME} "${STARTPATH} --daemon" 1>/var/log/parsoid_error.log 2>/var/log/parsoid_error.log &
fi
;;
'stop')
if [ -x ${STOPPATH} ]; then
daemon --user ${USERNAME} "${STOPPATH} --stop"
pkill -9 node
fi
;;
'restart')
$0 stop
$0 start
;;
'reload')
$0 stop
$0 start
;;
'status')
status -p "/var/www/html/wiki/parsoid.pid" parsoid
;;
*)
echo "Usage: parsoid {start|stop|status|restart|reload}"
exit 1
;;
esac
exit 0

To autostart on reboot, run:
chkconfig parsoid on

Download and install VisualEditor Extension https://www.mediawiki.org/wiki/Extension:VisualEditor

e.g. for this git snapshot
wget https://extdist.wmflabs.org/dist/extensions/VisualEditor-REL1_25-c947b49.tar.gz
tar -xzf VisualEditor-REL1_25-c947b49.tar.gz -C /var/www/html/wiki/extensions/

Depends on the UniversalLanguageSelector extension so ...
wget https://extdist.wmflabs.org/dist/extensions/UniversalLanguageSelector-REL1_25-7661826.tar.gz
tar -xzf UniversalLanguageSelector-REL1_25-7661826.tar.gz -C /var/www/html/wiki/extensions/

Setting up VisualEditor and Linking it to parsoid needs these modification in <wikidir>/LocalSettings.php

require_once "$IP/extensions/VisualEditor/VisualEditor.php";
// enable by default for everyone
$wgDefaultUserOptions['visualeditor-enable'] = 1;
// Don't allow users to disable it
$wgHiddenPrefs[] = 'visualeditor-enable';
// OPTIONAL: Enable visualeditor experimental code features.
# $wgDefaultUserOptions['visual-editorenable-experimental'] = 1;;
$wgVisualEditorParsoidURL = 'http://localhost:8000';
# $wgVisualEditorParsoidPrefix = 'chemwiki';

Parsoid Configuration file is /var/www/html/wiki/parsoid/api/localsettings.js

The basic file requires at least the following content ...

'use strict';

exports.setup = function(parsoidConfig) {
// The URL of your MediaWiki API endpoint.
parsoidConfig.setMwApi('localhost', { uri: 'http://localhost/wiki/api.php' });
parsoidConfig.setInterwiki( 'localhost', 'http://localhost/wiki/api.php' );
}

Testing parsoid on the command line ...

cd /var/www/html/wiki/parsoid
npm test
curl -L http://localhost/wiki/api.php

This should return a lot of HTML and not errors

Get the Git version
cd /tmp/
git clone -b REL1_24 https://github.com/wikimedia/mediawiki-extensions-VisualEditor.git
cd mediawiki-extensions-VisualEditor
git submodule update --init

Set appropriate permissions
cd /var/www/html/wiki/extensions/
sudo find VisualEditor -type d -exec chmod -R 575 {} \;
sudo find VisualEditor -type f -exec chmod -R 464 {} \;
sudo chown -R apache:webmaster VisualEditor
sudo chmod 575 VisualEditor/bin/*

Testing of the LATEX plugin. It seems superficially to work. Adding this wiki markup

zz

gives this:

<math>\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}</math>
