(1) Login Username vs. Wiki Username

TWiki manages internally two usernames: Login username and Wiki username.

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.

TWiki expands the following variables (enclosed in % percent signs):

Variable: Expanded to:
%WIKIHOMEURL% The base script URL of TWiki, is the link of the Home icon in the upper left corner, is http://freenetproject.org/twiki
%SCRIPTURL% The script URL of TWiki, is http://freenetproject.org/cgi-bin/twiki
%SCRIPTURLPATH% The path of the script URL of TWiki, is /cgi-bin/twiki
%SCRIPTSUFFIX% The script suffix, ex: .pl, .cgi is
%PUBURL% The public URL of TWiki, is http://freenetproject.org/twiki
%PUBURLPATH% The path of the public URL of TWiki, is /twiki
%ATTACHURL% The attachment URL of the current topic, is http://freenetproject.org/twiki/TWiki/TWikiVariables
Example: If you attach a file you can refer to it as %ATTACHURL%/image.gif
%ATTACHURLPATH% The path of the attachment URL of the current topic, is /twiki/TWiki/TWikiVariables
%URLPARAM{"name"}% Returns the value of a URL parameter. Ex: %URLPARAM{"skin"}% returns print for a .../view/TWiki/TWikiVariables?skin=print URL. Is

[2] Note: A web can be excluded from a web="all" search if you define a NOSEARCHALL=on variable in its WebPreferences.

Preferences Variables

Additional variables are defined in the preferences ( site-level ( SL ) in TWikiPreferences, web-level ( WL ) in WebPreferences of each web, and user level ( UL ) preferences in individual user topics):

Variable: Level: What:
%WIKIWEBMASTER% SL Webmaster email address (sender of email notifications) , is ian@freenetproject.org
%WIKIWEBLIST% SL List of TWiki webs (in upper right corner of topics)
%WEBTOPICLIST% WL Common links of web (second line of topics)
%WEBCOPYRIGHT% SL , WL Copyright notice (bottom right corner of topics)
%WEBBGCOLOR% WL Background color of web
%NOSEARCHALL% WL Exclude web from a web="all" search (set variable to on for hidden webs)
%NEWTOPICBGCOLOR% SL , UL Background color of non existing topic. ( UL needs authentication for topic views )
%NEWTOPICFONTCOLOR% SL , UL Font color of non existing topic. ( UL needs authentication for topic views )
%EDITBOXWIDTH% SL , UL Horizontal size of edit box, is 70
%EDITBOXHEIGHT% SL , UL Vertical size of edit box, is 17
%RELEASEEDITLOCKCHECKBOX% SL , UL Default state of the "Release edit lock" (UnlockTopic) check box in preview. Checkbox is initially checked if Set RELEASEEDITLOCKCHECKBOX = checked="checked", or unchecked if empty. If checked, make sure to click on Edit to do more changes; do not go back in your browser to the edit page, or you risk that someone else will edit the topic at the same time! Value is:
%DONTNOTIFYCHECKBOX% SL , UL Default state of the "Minor Changes, Don't Notify" (DontNotify) check box in preview. Check box is initially checked if Set DONTNOTIFYCHECKBOX = checked="checked", or unchecked if empty. Value is:
%ATTACHLINKBOX% SL , UL Default state of the link check box in the attach file page. Check box is initially checked if value is set to CHECKED , unchecked if empty. If checked, a link is created to the attached file at the end of the topic. Value is:
%HTTP_EQUIV_ON_VIEW% SL http-equiv meta tags for view, rdiff, attach, search* scripts.
%HTTP_EQUIV_ON_EDIT% SL , UL http-equiv meta tags for edit script.
%HTTP_EQUIV_ON_PREVIEW% SL , UL http-equiv meta tags for preview script.
%DENYWEBCHANGE% WL List of users and groups who are not allowed to change topics in the TWiki web. (More in TWikiAccessControl)
%ALLOWWEBCHANGE% WL List of users and groups who are allowed to change topics in the TWiki web. (More in TWikiAccessControl)
%DENYTOPICCHANGE% (any topic) List of users and groups who are not allowed to change the current topic. (More in TWikiAccessControl)
%ALLOWTOPICCHANGE% (any topic) List of users and groups who are allowed to change the current topic. (More in TWikiAccessControl)
%DENYWEBRENAME% WL List of users and groups who are not allowed to rename topics in the TWiki web. (More in TWikiAccessControl)

%ALLOWTOPICRENAME% (any topic) List of users and groups who are allowed to rename the current topic. (More in TWikiAccessControl)
%FINALPREFERENCES% SL , WL List of preferences that are not allowed to be overridden by next level preferences

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

(3) Notification of Changes by Email

Each TWiki web does an automatic email notification of recent changes. Users can subscribe / unsubscribe themselves in WebNotify of each TWiki web. The Perl script mailnotify is called by a deamon once every 60 minutes. For each Twiki web mailnotify is sending an automated email to subscribed users in case some topics changed within these 60 minutes.

Implementation note: Edit the cron table so that mailnotify is called every 60 minutes. Please consult man crontab of how to modify the table that schedules program execution at certain intervals. Example:

% crontab -e
15,45 * * * * (cd ~twiki/public_html/bin; ./mailnotify)
The above line will call mailnotify at 15 minutes and 45 minutes passed every hour.


(4) TWiki Category Table

It is possible to add a category table to a TWiki web. This permits storing and searching for more structured information. Editing a topic shows a HTML form with the usual text area and a table with selectors, checkboxes, radio buttons and text fields. The category table is shown at the end of a topic. The format of the category table can be defined per TWiki web.

If you want to use a Category Table in a TWiki web you need to have the following three files in the twiki/templates/{Yourweb} directory:

  • twikicatitems.tmpl : Defines the items in the table
  • twikicatedit.tmpl : Defines the look of the table when editing a topic
  • twikicatview.tmpl : Defines the look of the table when viewing a topic

Format of category definition template twikicatitems.tmpl

Valid lines:

select|{name}|{selSize}|{val1}|{val2}|{val3}...
checkbox|{name}|{checkFlag}|{itemsPerLine}|{val1}|{val2}|{val3}...
radio|{name}|{itemsPerLine}|{val1}|{val2}|{val3}...
text|{name}|{charSize}
# comments start with a # character

Explanation:

  {name}             name of tag
  {selSize}          vertical size of SELECT tag
  {val1}|{val2}...   values
  {checkFlag}        set to true for [Set] [Clear] buttons, else set to false
  {itemsPerLine}     input items per line before wrap around, 0 if no wrap around
  {charSize}         number of characters for text fields

Remark: Line radio|UseCategory|0|Yes|No has a special meaning. If present, it is possible to choose in "edit" if the category table is included in the topic or not

Example file:

radio|UseCategory|0|Yes|No, delete this category table
select|TopicClassification|1|Select one...|NoDisclosure|PublicSupported|PublicFAQ
checkbox|OperatingSystem|true|5|OsSolaris|OsSunOS|OsHPUX|OsWin
text|OsVersion|16

Format of twikicatedit.tmpl and twikicatview.tmpl

Use the example below and customize if needed. twikicatedit.tmpl and twikicatview.tmpl can be identical, but they do not have to be.

Attention: <!--TWikiCat--> is needed at the beginning and end as markers. Do not delete them!

Example:

<!--TWikiCat--> <h4> TWikiCategory </h4>
<table border="2" cellspacing="1" cellpadding="1">
%REPEAT%<tr>
<td valign="top" align="right"> %CATNAME%:  <br>%CATMODIFIER%</td><td>  %CATVALUE% </td>
</tr>%REPEAT%
</table><!--TWikiCat-->

Above template files will result in the following category table when viewing a topic:

TWikiCategory

TopicClassification:
PublicFAQ
OperatingSystem:
OsSolaris
OsVersion:
2.5 

Above template files will result in the following table when editing a topic:

TWikiCategory

UseCategory :
Yes    No, delete this category table   
TopicClassification :
OperatingSystem :
   
OsSolaris    OsSunOS    OsHPUX    OsWin   
OsVersion :

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">

(5) Implementation Notes

Platform

TWiki is written in PERL 5, but it uses also many shell command. The current implementation runs only on a Unix machine. RCS for revision control must be installed on the system.

Directories

Directory: Used for:
twiki/bin TWiki PERL scripts
twiki/pub Public files (FileAttachments, images)
twiki/data source text
twiki/templates HTML templates, used by TWiki scripts

Files in twiki/bin

File: Used for:
.htaccess.txt Authentication. Rename to .htaccess and customize if used
attach Script that shows the attach file page (FileAttachment)
changes Script that shows recent changes
delete (not used yet)
edit Script to edit a topic
mailnotify Script called by cron job to notify users of changes
oops Script that shows a OK or oops dialog
preview Script to preview topic after edit
rdiff Script to see differences of topics
register Script to register new users
save Script that saves a topic, called by preview
search Script that displays search results
upload Script that does file upload (FileAttachment)
view Script to view a topic ( the script )
viewfile Script to view an file attachment
wiki.pm main TWiki library
wikicfg.pm for initialization and configuration, used by wiki.pm


(6) Installation Notes

These installation steps use Apache web server on Linux as an example. TWiki should run on other web servers and Unix systems as well.

Note: These installation notes assume user nobody for all files manupulated by the cgi scripts (executed by the web server), and user twiki for all other files. You need to replace user nobody with an other user in case the web server executes the script with a different user ( default for Debian is www-data ). Also, you can substitute user twiki with your own user name.

  • Request the TWiki distribution (in Unix ZIP format) from http://www.mindspring.com/~peterthoeny/twiki/ .
  • 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 .
  • 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 ).
  • 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.
  • On systems where the Perl scripts require a file extension you need to:
    • Rename all scripts in the twiki/bin directory to have a file extension, i.e. rename view to view.cgi .
    • Specify this file extension in the $scriptSuffix variable in twiki/bin/wikicfg.pm .
  • 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 .
  • Point your browser at http://your.domain.com/twiki/bin/view and start wiki-ing away!
  • Note in case cgi user is not nobody : 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 , 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)

  • 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://freenetproject.org/cgi-bin/twiki/statistics
      • Update current month for Main web only:
        http://freenetproject.org/cgi-bin/twiki/statistics/Main
      • Update January 2000 for Main web:
        http://freenetproject.org/cgi-bin/twiki/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 , WebNotify.txt , WebSearch.txt , WebStatistics.txt , webcolor.inc and weblist.inc 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.
    • Change webcolor.inc to a color of your taste. The number represents the unique color for the web (consult an HTML book for colors.) Note: The file must not have a new line, just the number without a return.
    • Customize weblist.inc (web specific links on top) if needed.
    • Add the new web in twiki/data/wikiwebs.inc (web specific links on top) and twiki/data/wikiwebtable.inc (table of all webs at the end of the WebHome topics).
    • In case you need a web specific copyright notice (at the bottom), copy file webcopyright.inc from the twiki/data directory to the new data directory, and customize it.
    • 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 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:
