The Mediawiki VisualEditor is a Wysiwyg editor for Mediawiki versions that came out in late 2014. The system is also deployed in most Wikipedia versions (however since it is still in Beta, only registered users can use it). Installation of this extension is more complex than usual and requires two components:
- Parsoid, a combined MediaWiki and HTML parser implemented with Node.js
I managed to get this installed and working, both on a test server and in this wiki. Anyhow, VisualEditor does seem work on MediaWiki 1.24 and 1.25 and 1.27 but the installation is very tricky and the software combination needs to be right. VisualEditor also seems to handle most pages that include templates and semantic forms. I don't think that semantic tags will work, but since we always use semantic forms that is more or less ok. Though, I consider moving forms-based pages into a special name space. Will have to do some extra testing however - Daniel K. Schneider (talk) 18:38, 26 June 2014 / Sept. 2015.
Notice: This extension sometimes breaks (depending on the combo of installed versions) - Daniel K. Schneider (talk) 15:48, 19 September 2014 - Daniel K. Schneider (talk) 12:37, 17 April 2015 (CEST). Therefore upgrade your wiki on a test server first, if you are keen to have this working all the time.
2 Installation notes for MW 1.27x under Ubuntu 16.x
It seems to be working for now - Daniel K. Schneider (talk) 20:01, 6 December 2016 (CET)
- A node.js server and its npm package manager must be installed on your machine. To check if it exists, type
sudo apt-get install nodejs sudo apt-get install npm
- Curl must be installed, including the php library.
sudo apt-get install curl sudo apt-get install php7.0-curl sudo apt-get install php-curl sudo apachectl restart
2.2 Installation of Parsoid
Parsoid is a service that will run under node.js server and that will do the backend of the editing process, i.e. parse MediaWiki and HTML.
If you have old developper versions installed it could be a good idea to remove these. My new install only started working after:
sudo apt-get --purge remove parsoid rm -r /usr/lib/parsoid etc.
My system admin skills are fairly low and I cannot explain why I had to remove every trace of an old parsoid...
sudo apt-key advanced --keyserver pgp.mit.edu --recv-keys 90E9F83F22250DD7 sudo apt-add-repository "deb https://releases.wikimedia.org/debian jessie-mediawiki main" sudo apt-get install apt-transport-https sudo apt-get update sudo apt-get install parsoid
Edit file /etc/mediawiki/parsoid/config.yaml
For each wiki, add two lines likes this under mwApis:, one that defines the URL for the API and the other that gives a domain name (same as the one used in LocalSettings.php). Make sure the the API URL does work !
mwApis: - # This is the only required parameter, uri: 'http://edutechwiki.unige.ch/test/api.php' domain: 'test' - # This is the only required parameter, uri: 'http://edutechwiki.unige.ch/your_wiki/api.php' domain: 'your_wiki'
sudo service parsoid restart
2.3 Installation of the extension
(tested with MW 1.31, Sept. 2018)
Take the one from the official extensions directory and just extract the archive.
For example, do not use this, the URL will change
cd extensions git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/VisualEditor.git cd VisualEditor git submodule update --init
Make sure to select the right version, 'master' probably will not work. Checkout the good version and update the submodule again
git checkout REL1_27 git submodule update --init
but, as we said above, for once it is a safer bet to get this extension from the distributor and not via git ....
# Visual Editor wfLoadExtension( 'VisualEditor' ); // Enable by default for everybody $wgDefaultUserOptions['visualeditor-enable'] = 1; // Optional: Set VisualEditor as the default for anonymous users // otherwise they will have to switch to VE // $wgDefaultUserOptions['visualeditor-editor'] = "visualeditor"; // Don't allow users to disable it $wgHiddenPrefs = 'visualeditor-enable'; // OPTIONAL: Enable VisualEditor's experimental code features #$wgDefaultUserOptions['visualeditor-enable-experimental'] = 1; $wgVirtualRestConfig['modules']['parsoid'] = array( // URL to the Parsoid instance // Use port 8142 if you use the Ubuntu or Debian packages 'url' => 'http://your.full.site:8142', // Parsoid "domain" -- ADAPT TO YOUR NEED, i.e. replace "your_wiki" by the same "domain" name you gave in the yaml.config file. 'domain' => 'your_wiki' );
2.4 Allow visual editing in more than default namespaces
Example (adapt to yours)
$wgVisualEditorAvailableNamespaces = [ "0" => true, "2" => true, "102" => true, "104" => true, "106" => true, "_merge_strategy" => "array_plus"];
Tip: Look at the HTML source of Special:AllPages. The HTML options menu will list the numbers for your namespaces.
2.5.1 New installation is not working
It is really really crucial to get the URLs right in the various configuration files
1) Control if Apache is ok. On the command line, type:
sudo apache2ctl -S
Depending on your installation you should get something like this (and not some random name that does not match your wiki URL !!)
VirtualHost configuration: 220.127.116.11:* edutechwiki.unige.ch (/etc/apache2/sites-enabled/mediawiki.conf:1)
Make very sure that in your Apache mediawiki.conf file you get the right name of your Internet alias, for example:
<VirtualHost edutechwiki.unige.ch> ServerAdmin ....@..... ServerName edutechwiki.unige.ch
2) Make sure that the Parsoid domain is correct and consistent.
3) Uninstall old code and configuration files and start fresh.
2.5.2 Parsoid did work and stopped working
This arrived on March 28, 2018, Ubuntu Server 16.04 / Mediawiki 1.27.4. According to a post on Mediawiki one should install an old version. Firstly make sure that this is the problem
apt-cache show parsoid
If it shows pool/main/p/parsoid/parsoid_0.9.0all_all.deb then you got version 9 and you could try downgrading. It's probably safer than trying to install a new visual editor that also can break everything, but I just do not know. Also make sure to copy the configuration files in case they go away.
apt-get purge parsoid wget https://people.wikimedia.org/~ssastry/parsoid/debs/parsoid_0.8.0all_all.deb dpkg -i parsoid_0.8.0all_all.deb apt-mark hold parsoid
Remember what you did here.
apt-mark hold prevents installing a new package. Revert this after installing a new evething ...
apt-mark unhold parsoid
2.6 https support
- Is possible, read the official manual page (not tested so far)
- Requires getting and installing certificates...
3 Tips for old version
I had VisualEditor going for MW 1.25. After that it broke. You can browse through the wiki history if you are really interested in that ...
