Initial setup[edit | edit source]

There are four basic steps to installing pywikibot:

  1. Download or update Python,
  2. Decide which version to use,
  3. Download pywikibot,
  4. Configure pywikibot's basic settings.

Downloading Python[edit | edit source]

Unix systems
typically have a recent-enough version of Python (2.5 for compat, 2.7 for core) installed. Check with python --version.
Mac OS X 10.8+
has a version of Python that is recent enough to run pywikibot. If you run an older OS X, or are unsure, download and install Python 2.7.6 from http://www.python.org/downloads/
Windows
download and install the latest release Python 2.7 from http://www.python.org/downloads/
Python version
The following versions of Python are supported:
Python version pywikibot compat pywikibot core
Former release pywikipedia trunk pywikibot rewrite branch
<= 2.3 no support no support
2.4 no PLURAL support, only few scripts supported. Not supported anymore

3.2
no support no support
3.3 — 3.4 OK

Two versions of pywikibot[edit | edit source]

There are two branches under active development. You can choose between:

  • Core (formerly rewrite), which should be your first choice. If you don't know what to choose, take this branch.
  • Compat (formerly trunk) is an older version of the framework. If you are editing on old wikis (pre-1.16 or so), or require one of the scripts that is not available on core yet (see the compatibility list), this is what you want.

Note Note: Due to an Unicode bug in the underlying python library, python version 2.7.2 or higher is strictly recommended for Wikimedia projects using the Compat branch. See also the requirements for a bot, which describes needed python version and pywikibot branches.

Download Pywikibot[edit | edit source]

The easiest way to download Pywikibot is to use the latest nightly release. Just download the pywikibot zip file to your computer and decompress the file – there is no further installation required.

Download Pywikibot with Git[edit | edit source]

For installing with Git you need to run:

For core (formerly "rewrite")
git clone --recursive https://gerrit.wikimedia.org/r/pywikibot/core.git
For compat (formerly "trunk")
git clone --recursive https://gerrit.wikimedia.org/r/pywikibot/compat.git

With the --recursive option it automatically installs the required submodules. Currently there are two submodules (i18n and spelling); one of them (i18n) is really required even for English language bots:

#i18n
git clone https://gerrit.wikimedia.org/r/pywikibot/i18n.git
#spellchecker database
git clone https://gerrit.wikimedia.org/r/pywikibot/spelling.git

Download Pywikibot with SVN[edit | edit source]

If you don't want to use Git you can still use SVN.

Windows user may use the GUI extension TortoisSVN, see next section below.

For installing with SVN you should run

For core (formerly rewrite)
svn co https://github.com/wikimedia/pywikibot-core/trunk core
cd core/scripts
svn co https://github.com/wikimedia/pywikibot-i18n/trunk i18n
For compat (formerly trunk)
svn co https://github.com/wikimedia/pywikibot-compat/trunk compat
cd compat
svn co https://github.com/wikimedia/pywikibot-i18n/trunk i18n
Download Pywikibot with TortoiseSVN for Windows user[edit | edit source]

TortoiseSVN is a Windows shell extension with GUI working as SVN client. You may download the current release at http://tortoisesvn.net/downloads.html. If you like using TortoiseSVN you may use it as follows:

For core release (formerly rewrite)
  1. Right-click on your prefered directory and execute "Start SVN checkout..."
  2. Choose "URL of repository" and paste the URL https://github.com/wikimedia/pywikibot-core/trunk
  3. Choose "Checkout directory and change the default directory which is <your prefered directory>/pywikibot-core e.g. to <your prefered directory>/svn-core if you like.
  4. Confirm with [ OK ]
Now we have to install external libraries used by the framework. There are different ways to do that e.g. again with the checkout command. Another way is using properties. You may set it manually but it is very easy to use the preference file named .svnprops coming with the framework which sets all the needed properties:
  1. Right-click your working directory
  2. Select the last item in the drop list which might be folder's "Properties"
  3. Select "Subversion" tab and click on [ Properties... ] button
  4. click [ Import... ] and select the file ".svnprops" in your framework folder
  5. Confirm with [ OK ] for property settings
  6. Confirm with [ OK ] for folder properties
  7. Now right-click onto your working copy and select "SVN update" to download the external libraries.
For compat release (formerly trunk)
  1. Right-click on your prefered directory and execute "Start SVN checkout..."
  2. Choose "URL of repository" and paste the URL https://github.com/wikimedia/pywikibot-compat/trunk
  3. Choose "Checkout directory and change the default directory which is <your prefered directory>/pywikibot-compat e.g. to <your prefered directory>/svn-compat if you like.
  4. Confirm with [ OK ]
Now we have to install external libraries used by the framework. There are different ways to do that e.g. again with the checkout command. Another way is using properties in a similar way as in core release.
Updating the working copy

Right-click on your working copy and choose "SVN Update"

Shortcut in command line[edit | edit source]

To allow your source code to be developed outside of the pywikibot source directory, add something like:

PYTHONPATH=$PYTHONPATH:~/pywikipedia/
export PYTHONPATH

to a file that gets run on login, usually ~/.bashrc - this avoids typing the export PYTHONPATH part in each time you log in. Naturally, change paths to match your installation.

Similarly, you can set the PYWIKIBOT_DIR environment variable to specify the directory in which user-specific information is stored (in particular, user-config.py which contains login data for the bot).

Windows users: create a shortcut[edit | edit source]

How to make a quick shortcut to run commands (Windows users):

If you're installing Pywikibot in a folder such as "My Documents" it may be troublesome to repeatedly use the "chdir" command to go into the folder to run the bots.

On Windows you can create a shortcut which will open the command box which you can use to run bots easily. Just follow these steps to create one:

  1. Right click the folder pywikibot is installed in.
  2. Click "Create shortcut". A new shortcut icon with the arrow key will be created.
  3. Right click on the new shortcut, and click properties.
  4. In the properties window, in the target box type in cmd.exe.
  5. In the "start in" box enter the full address of pywikibot.
  6. Click "OK".
  7. Click the shortcut and the cmd.exe opens up with the full path listed.
    If you press F5 to refresh the window (or re-open the shortcut's properties), you will notice that the shortcut icon has changed.

Updating[edit | edit source]

The pywikibot framework is a perpetual beta software. Bugfixes, new options, new behavior and changes of the mediawiki software leads to frequently new releases and needs the working copy code to be up to date. Please update your branch regularly (daily period or at least once a week).

Updating nightly dump[edit | edit source]

  • If you are using a nightly version, the process is a bit more complicated. You have to re-download a full copy from here. Before installing it, backup your configuration files and scripts (user-config.py, any family file, or custom script that you might have created, and any current dump xml file you're using for a wiki). Replace your pywikibot directory by the new version you just downloaded. Restore your configuration files. If you're not sure of what you're doing, do not erase but keep a backup of your complete old pywikibot directory, to avoid losing any important files.
If you have changed some scripts of the framework, you have to merge the differences by yourself. Version control systems like git or svn does it automatically.

Updating git[edit | edit source]

  • If you used Git for downloading Pywikibot, you must go to the your directory and run the following command:
git pull --all
  • You may need to do
    git submodule update
    
    as well, if you need up-to-date i18n files.
Automatic updating git on Wikimedia Labs or Toolserver[edit | edit source]

For automatic updating you can make update bash file and put it in root and fill it with these commands, For WMF labs (in your service group):

#!/bin/bash
cd /data/project/yourservicegroup/pywikipedia
git pull --all && git submodule update

and then run crontab -e and enter the following to make your bot to run every day at 00:00AM (midnight):

0 0 * * * bash /data/project/yourservicegroup/update >/dev/null 2>&1

Notice: in these cods yourservicegroup is name of your service group (without "-local").

For auto-updating in toolserver you just need to as the same as above but instead of "/data/project/yourservicegroup/" you need to enter "/data/project/yourusername/" which is "yourusername" is your user name!

Updating svn[edit | edit source]

To update the code for core branch:

svn up core/trunk
cd core/scripts 
svn up i18n

To update the code for compat branch:

svn up compat/trunk
cd compat
svn up i18n
Updating with TortoiseSVN (for Windows user)[edit | edit source]

Updating the working copy with TortoiseSVN is just easy: Right-click on your working copy directory and choose "SVN Update"

Dependencies[edit | edit source]

Compat[edit | edit source]

The pywikibot framework is quite a big and complex code and some scripts needs external python modules (libraries) from other sources also in order to work properly. The dependencies can be installed manually or automatically (not supported by core yet).

If any issues arise during installation (of dependencies) please file a bug report or write to the pywikipedia-l maillist.

Automatic (recommended)[edit | edit source]

If available this is the recommended way, because this will result in an identical setup on all machines. All you have to do is just execute your favorite script after installation (for example, python pwb.py clean_sandbox.py -simulate) and pywikibot will ask you whether you want to install missing packages, and continue to ask questions on how you want to configure your local copy.

Packages will be installed from OS package management if possible (all Linux, not under win). If they cannot be found they will be downloaded as archive from original source, extracted and installed. In the course of this process a few packages have to be slightly modified in order to work seamlessly with pywikibot. This modification needs an additional binary tool called patch (patch.exe under win). Unfortunately this is not available from MS; however, we can use a port of the original linux code (gnuwin32 patch.exe)

It is worth mentioning here that - despite the OS package management "install mode" - all files are installed locally into the externals/ directory of pywikibot. This is a very useful feature for users that do not have permission to install software to their system, e.g. non-admins.

Manual (for experts)[edit | edit source]

In order to install the needed packages manually, you first need to know which ones. A full list of all needed modules can be found in externals/__init__.py and contains:

  • framework core code:
    • i18n [git submodule]
    • spelling [git submodule]
    • httplib2 [git submodule]
    • BeautifulSoup.py [included since important]
    • patch.exe
  • depending of which script will be used:
    • opencv, opencv/haarcascades [git submodule]
    • pycolorname [git submodule]
    • irclib
    • mwparserfromhell
    • parse-crontab
    • odfpy
    • openpyxl
    • python-colormath
    • jseg, jseg/jpeg-6b
    • mlpy
    • music21
    • ocropus
    • pydmtx
    • py_w3c
    • zbar
    • (slic)
    • (bob, xbob_flandmark)

Which ones you really need, depends strongly on the script you intend to run - if you are unsure use the automatic mode above. In order to check correct installation just run a bot script. If the dependencies are satisfied everything will be ok, else the framework will complain and ask whether it should install missing packages automatically.

Core[edit | edit source]

Use pip to install dependencies.

Setup on Wikimedia Labs/Tool Labs server[edit | edit source]

In order to install your bot onto the Wikimedia servers and run it from there, make sure first to become familiar with Wikimedia Labs/Tool Labs environment.

In the next step you have to request several accounts (for labs, for the tools project, your tool), provide an ssh key and so on. How to do this and then proceed, is described in full detail in Setup pywikibot on Labs.

Pywikibot source repo moved (from svn) to git, please confer Manual:Pywikipediabot/Gerrit first.

The bots projects here has become obsolete use tools now, in order to do so follow Tools/Help to get an account. Then create your tool (service group).

If you used the toolserver in the past and know how everything used to work there, confer migrating from toolserver for more info.

Now you are ready to start. Login to Labs tools project:

$ ssh USERNAME@tools-login.wmflabs.org

switch to the tool account with

maintainer@tools-login:~$ become toolname
local-toolname@tools-login:~$ 

Now install/clone the pywikibot code to your tool account as described below.

Install the bot code[edit | edit source]

core[edit | edit source]

Similar to the instructions given in this mail do:

$ git clone --recursive https://gerrit.wikimedia.org/r/pywikibot/core.git pywikibot-core
$ cd pywikibot-core 

Now you have to setup pywikibot. Choose any one of the following processes to configure your system:

  • Execute python generate_user_files.py
  • Run your favorite bot script (e.g. python pwb.py clean_sandbox.py -simulate) since you are doing this in a fresh clone, it will trigger a bunch of questions on how you want to configure your local copy, answer them carefully in order to proceed.
  • If you already have a config file(s) from a previous version, you can copy those existing files into the right places (e.g. pywikibot-compat/).


Further things you might have to do (depending on what bot scripts you want to run) is to setup all externals properly - which still has to be done manually in core

$ cd externals
$ cat README 

and follow the instructions there.

You will also have to enter the password for your bot eventually.

Now you have finished the configuration of core and can continue setting up the jobs to execute.

compat[edit | edit source]

Do:

$ git clone --recursive https://gerrit.wikimedia.org/r/pywikibot/compat.git pywikibot-compat

Now, as similarly described in the core section above, you have to setup pywikibot. Choose any one of the following processes to configure your system:

  • Execute python generate_user_files.py
  • Run your favorite bot script (e.g. python pwb.py clean_sandbox.py -simulate) since you are doing this in a fresh clone, it will trigger a bunch of questions on how you want to configure your local copy, answer them carefully in order to proceed.
  • If you already have a config file(s) from a previous version, you can copy those existing files into the right places (e.g. pywikibot-compat/).


See this article for more details on configuring your bot including creating the files manually. You may setup all externals manually if you want - but this is not needed in compat, confer Manual:Pywikipediabot/Installation#Dependencies for further info.

You will also have to enter the password for your bot eventually.

Now you have finished the configuration of compat and can continue setting up the webspace and jobs to execute.

Setup the webspace[edit | edit source]

Per default, the directory listing on http://tools.wmflabs.org/TOOLNAME is disabled. If you want to allow it for all users, login to your tool account (as already described) and

$ cd ~/public_html
$ echo Options +Indexes >> .htaccess 

If you run a bot with the -log option, you will find the log files within the logs/ directory. If you want to allow users to access it from the web, do

$ cd ~/public_html
$ mkdir logs
$ cd logs
$ ln -s ~/pywikibot-core/logs cor 

If you want a specific file type to be handled differently by your browser, e.g. .log files like text files, use (confer this)

$ echo AddType text/plain .log >> .htaccess

and (don't forget to) clear your browsers cache afterwards.

Next you might want to consider you cgi-bin directory

$ cd ~/cgi-bin

follow the hints given at wikitech:Nova Resource:Tools/Help#Logs exactly, e.g. even the two commands

$ /usr/bin/python      # valid
$ /usr/bin/env python  # in-vali 

work and do the same in shell, only the first one is valid and works here, the second is invalid! Another point to mention is that PHP scripts go into public_html, not cgi-bin. Python scripts on the other hand can be placed in public_html or cgi-bin as you wish. I would recommend to use public_html for documents and keep it listable, whereas cgi-bin should be used for CGI scripts and be protected (not listable).

Setup the job submission[edit | edit source]

In order to setup the submission of the jobs you want to execute and use the grid engine you should first consider wikitech:Nova Resource:Tools/Help#Submitting, managing and scheduling jobs on the grid and if you are familiar with the Toolserver and its architecture consult Migrating from toolserver also.

In general labs uses SGE and its commands like qsub et al, this is explained in this document which you should use in order to get an idea which command and what parameters you want to use.

An infinitely running job (e.g. irc-bot) like this (cronie entry from TS submit host):

06 0 * * * qcronsub -l h_rt=INFINITY -l virtual_free=200M -l arch=lx -N script_wui $HOME/rewrite/pwb.py script_wui.py -log

becomes

$ jsub -once -continuous -l h_vmem=256M -N script_wui python $HOME/pywikibot-core/pwb.py script_wui.py -log

or shorter

$ jstart -l h_vmem=256M -N script_wui python $HOME/pywikibot-core/pwb.py script_wui.py -log

the first expression is good for debugging. Memory values smaller than 256MB seam not to work here, since that is the minimum. If you experience problems with your jobs, like e.g.

Fatal Python error: Couldn't create autoTLSkey mapping

you can try increasing the memory value - which is also needed here, because this script uses a second thread for timing and this thread needs memory too. Therefore use finally

$ jstart -l h_vmem=512M -N script_wui python $HOME/pywikibot-core/pwb.py script_wui.py -log

Now in order to create a crontab follow Scheduling jobs at regular intervals with cron and setup for crontab file like:

$ crontab -e

and enter

PATH=/usr/local/bin:/usr/bin:/bin

06 0 * * * jstart -l h_vmem=512M -N script_wui python $HOME/pywikibot-core/pwb.py script_wui.py -lo 

Additional configuration[edit | edit source]

Furthermore additional tools to support you and your bot at work are available:

Additional configuration[edit | edit source]

Creating user files[edit | edit source]

As a final step before using the bot scripts, you have to create user configuration files. The main one is user-config.py. If you execute your favorite script after installation (for example, python pwb.py clean_sandbox.py -simulate) then pywikibot ask questions on how you want to configure your local copy and will create these files. You can also run generate user files.py to create these files.

Running Pywikibot under Windows[edit | edit source]

Please notice the instruction at Manual:Pywikibot/Windows.

Verifying your installation[edit | edit source]

With the core branch, entering in the command line

python pwb.py login

should prompt for the login password for your bot, and then report

Logged in on somewiki:lang as bot username.
