Wiki username: Is your name in WikiNotation, e.g. PeterThoeny. When you create your own home page topic, you should use your WikiName for the topic name. Like that, your name will be linked automatically where ever it is used. Please create your home page in TWiki.Main, not any other TWiki web.
Note: When you write a WikiName of a user (your own or somebody else's) be sure to specify the Main web in front of the Wiki user name, e.g. write it as Main.wikiUsername. This assures that the name will be linked automatically to the TWiki.Main web, even if the text is written in a different Wiki web.
TWiki can map the Intranet username to the Wiki username automatically, provided that the Login username and Wiki username pair has been entered in the TWikiUsers topic.
(2) Wiki Variables
TWiki Variables
Text strings expanded on the fly to display data or system info
Overview
TWikiVariables are text strings - %VARIABLE% - that expand into content whenever a page is opened. Variables are replaced by their actual values: stored data, or system info (like the date, or the current user). There are predefined variables, and Preference variables that you set. You can also define custom variables, with new names and values.
Predefined Variables
Most predefined variables return values that were either defined when TWiki was installed, or taken from server info (like current username, or date and time). Many of the variables let you control how the formatted results appear.
netfrag.org expands the following variables (enclosed in % percent signs):

Setting Preferences
The syntax for Preferences variables is the same anywhere in TWiki. In Edit mode, from the start of a new line: [6 spaces] * [space] Set [space] VARIABLENAME [space] = [value] Example:
Set VARIABLENAME = value
Creating Custom Variables
You can add your own preference variables for an entire site, a single web, or a single topic, using the standard syntax. Whatever you include in your variable will be expanded on display, and treated exactly as if it had been written out. So you can place formatted text, page links, image paths.
Example: Create a custom logo variable
To place a logo anywhere in a web by typing %MYLOGO%, simply define the variable on the web's WebPreferences page. You also have to upload logo.gif - this can be done by attaching a file to LogoTopic (any topic name you choose):
Set MYLOGO = %PUBURL%/%MAINWEB%/LogoTopic/logo.gif
Above template files will result in the following table when editing a topic:
Note: It is possible to force the values of a category table when creating a new topic. This is useful to create new topics using a form for the topic name. The default values of the category table can be specified as hidden fields if needed, i.e. <input type="hidden" name="someCategory" value="someValue">
Example (edit this page to see the source) :
Create directory /home/httpd/twiki and unzip the TWiki distribution to this directory.
The twiki/bin directory of TWiki must be set as a cgi-bin directory. Add /home/httpd/twiki/bin to /etc/httpd/conf/access.conf with only ExecCGI option.
The twiki/pub directory of TWiki must be set so that it is visible as a URL. Add /home/httpd/twiki/pub to /etc/httpd/conf/access.conf with normal access options (copy from /home/httpd/html).
Now add Alias for /twiki/pub and ScriptAlias for /twiki/bin to /etc/httpd/conf/srm-conf .
Restart Apache by /etc/rc.d/rc5.d/S85httpd restart .
Test if the twiki/bin directory is cgi-enabled:
Enter the URL of that directory into your browser ( http://your.domain.com/twiki/bin ). It is not set correctly as cgi-bin in case you get something like "Index of /twiki/bin" . It is OK if you get a message like "Forbidden. You don't have permission to access /twiki/bin/ on this server."
Execute the testenv script from your browser ( http://your.domain.com/twiki/bin/testenv ). It should show a table of all CGI environment variables.
Make sure PERL and the PERL CGI library is installed on your system. Default location of PERL executable is /usr/bin/perl . In case PERL is installed in a different location, the first line of all perl scripts in the twiki/bin directory need to be changed (alternatively you can create a symbolic link from /usr/bin/perl ).
To be able to edit the perl scripts and .tmpl files it is necessary to chown and chgrp -R twiki so all the files have the owner you want.
The scripts execute as nobody . Set the file permission of all Perl scripts in the twiki/bin directory as executable to -rw-r-xr-x .
Set the file permission of all files below twiki/data to 666 ( -rw-rw-rw- ).
Set the file permission of the twiki/data directory and all its subdirectories to 777 ( drwxrwxrwx ).
Set the file permission of the twiki/pub directory to 777 ( drwxrwxrwx ).
Edit the file twiki/bin/wikicfg.pm and set the variables at the beginning of the file to your needs.
Make sure RCS is installed. In case RCS is not in the path environment variable, add it to path . Alternatively, add the full path name to the rcs, ci, co, rlog, rcsdiff commands in the variables of twiki/bin/wikicfg.pm .
Note in case cgi user is notnobody : The *,v RCS repository files delivered with the installation package are locked by user nobody . In case the user is different (e.g. www-data ), it is not possible to check in files, this has the effect that the topic version number does not increase when saving a topic. In this case you need to unlock all repository files and lock them as user www-data (check the rcs man pages), or simply delete all the repository files.
Security issue: Directories twiki/data , twiki/templates and all its subdirectories should be set so that they are not visible as a URL. (Alternatively, move the directries to a place where they are not visible, and change the variables in twiki/bin/wikicfg.pm accordingly)
Enable email notification of topic changes, (3) has more.
Optional: You can add new rendering rules or new %variables%. To insure an easy upgrade of TWiki it is recommended to do this customization in twiki/bin/wikicfg.pm , not twiki/bin/wiki.pm .
Optional: If you are on a public server and you would like to authenticate users you need to rename file .htaccess.txt in the twiki/bin directory to .htaccess and change it to your needs. For details consult the HTTP server documentation (for Apache server: [1], [2], [3]). Note: In case .htaccess does not have any effect you need to enable it: Add "AllowOverride All" to the Directory section of access.conf for your twiki/bin directory.
Optional: You can automatically generate usage statistics for all webs. To enable this:
Make sure variable $doLogTopicView, $doLogTopicSave and $doLogTopicUpload in wikicfg.pm are set. This will generate log entries in file twiki/data/log<date>.txt .
Topic WebStatistics must be present in all webs where you want to have statistics. You can use the topic in the Main web as a template.
Call the twiki/bin/statistics script from a cron job, once a day is recommended. This will update the WebStatistics topics in all webs.
Attention: The script must run as the same user as the CGI scripts are running, which is user nobody on most systems. Example crontab entry: 0 0 * * * (cd /path/to/TWiki/bin; ./statistics >/dev/null 2>&1)
There is a workaround in case you can't run the script as user nobody : Run the utility twiki/bin/geturl in your cron job and specify the URL of the twiki/bin/statistics script as a parameter. Example: 0 0 * * * (cd /path/to/TWiki/bin; ./geturl mydomain.com /urlpath/to/TWiki/bin/statistics >/dev/null 2>&1)
The twiki/bin/statistics script can also be executed as a CGI script, just enter the URL in your browser. Examples:
Update current month for all webs: http://mydomain.com/twiki/bin/statistics
Update current month for Main web only: http://mydomain.com/twiki/bin/statistics/Main
Update January 2000 for Main web: http://mydomain.com/twiki/bin/statistics/Main?logdate=200001
To create a new web:
Use a name for the web consisting of characters A..Z , a..z but not in WikiNotation.
Create a new template directory under twiki/templates .
Create a new data directory under twiki/data and check the file permission of the directory.
Copy the files WebHome.txt , WebPreferences.txt , WebNotify.txt , WebSearch.txt and WebStatistics.txt from the twiki/data/Main directory to the new data directory, preserving the original files' owner, group and permissions ( on Unix use cp -p ). The data files must be writable by the owner the CGI scripts are running on ( usually nobody ). Hint: You can set permissions of .txt and .txt,v files to -rw-rw-rw- and then edit the topic using your browser, RCS will restore the file permission correctly when saving the topic.
Add the new web to the web list (on top of each topic) by editing the site-level preferences TWikiPreferences?:
Add the new web to the WIKIWEBLIST variable.
Add the new web to the web table (at the bottom of each WebHome topic) by editing the TWikiWebsTable? topic.
Change the web preferences by editing the WebPreferences topic of the new web:
Set the WEBBGCOLOR variable to a color of your taste. The number represents the unique color for the web (consult an HTML book for colors.)
Customize the WEBTOPICLIST variable to contain the web specific links you prefer.
Optional: Set the WEBCOPYRIGHT variable to have a web-specific copyright text (at the bottom of each topic).
If needed, create customized templates in the new templates directory. (Non existing templates are inherited from twiki/templates )
If you want to use a category table, copy the three files twikicatitems.tmpl , twikicatedit.tmpl and twikicatview.tmpl from the twiki/templates/Know directory to the new templates directory, and customize it. The TWiki Category Table section has more.
In case you want usage statistics for this web: Copy file WebStatistics.txt from the twiki/data/Main directory to the new data directory. Edit topic WebStatistics in the new web and delete old usage entries.
Here are contents of directories with file permissions. Please note that this is for debugging reasons only and does not exactly reflect the distribution:
