**History of the TWiki Implementation (version TWiki-4.1.2, Sat, 03 Mar 2007, build 13046)** - [[PeterThoeny]] - 23 Jul 1998: Installed initial version, based on the JOS Wiki.

(Technically speaking a simple '.\*' search on topic names.) - [[PeterThoeny]] - 28 Jul 1998: Topic [[WebChanges]] shows Wiki username instead of Intranet username, e.g. `PeterThoeny` instead of `thoeny` in case the Wiki username exists. Implementation: Automatic lookup of Wiki username in topic [[TWikiUsers]]. - [[PeterThoeny]] - 28 Jul 1998: Added TWiki variables, enclosed in % signs: `%TOPIC%` (Topic name), `%WEB%` (web name), `%SCRIPTURL%` (script URL), `%DATE%` (current date), `%WIKIWEBMASTER%` (Wiki webmaster address), `%WIKIVERSION%` (Wiki version), `%USERNAME%` (user name), `%WIKIUSERNAME%` (Wiki user name). - [[PeterThoeny]] - 31 Jul 1998: Support for quoted text with a '>' at the beginning of the line. - [[PeterThoeny]] - 04 Aug 1998: Warn user if new topic name is not a valid Wiki name. (template file templates/Web/notwiki.tmpl) - [[PeterThoeny]] - 04 Aug 1998: Separate templates for text of non existing topic and default text of new topic. (template file templates/Web/notedited.tmpl) - [[PeterThoeny]] - 05 Aug 1998: Signature and date is inserted automatically when creating a new topic. - [[PeterThoeny]] - 06 Aug 1998: Added server side include of files.

Each web has a topic [[WebNotify]] where one can subscribe and unsubscribe. - [[PeterThoeny]] - 13 Aug 1998: [[WikiNotation]] allows also numbers after the `AaA` sequence, e.g. `AaA1` is a valid [[WikiTopic]] name, but not `Aa1`. - [[PeterThoeny]] - 24 Sep 1998: Corrected templates for automatic email notification so that MS Outlook can display attachment as an HTML file. - [[PeterThoeny]] - 13 Oct 1998: Alphabetical topic index in [[WebSearch]]. - [[PeterThoeny]] - 14 Oct 1998: Refered-By: Find out which topics have a link to the current topic. Each topic has a |Ref-By| link for that. Note: Only references from the current web are shown, not references from other webs. - [[PeterThoeny]] - 26 Oct 1998: Added revision control using RCS. Each topic has now a list of revisions at the bottom and a revision info, e.g.
Topic TWikiHistory . \{ Edit | Ref-By | r1.3 | r1.2 | r1.1 \}
Revision r1.3: 1998/10/26 01:34:00 by [[PeterThoeny]] - [[PeterThoeny]] - 26 Oct 1998: Added preview of topic changes before saving the topic. This was necessary to prevent unneeded revisions. - [[PeterThoeny]] - 10 Nov 1998: View differences between topic revisions. Each topic has a list of revisions (e.g. `r1.3`) and differences thereof (e.g. `>`) at the bottom:
Topic TWikiHistory . \{ Edit | Ref-By | r1.3 | > | r1.2 | > | r1.1 \}
Revision r1.3: 1998/11/10 01:34 by [[PeterThoeny]] - [[PeterThoeny]] - 10 Nov 1998: The email notification and the Changes topic have now a topic date that is linked. Clicking on the link will show the difference between the two most recent topic revisions. - [[PeterThoeny]] - 18 Nov 1998: Internal log of topic save actions to the file `data/logYYYYMM.txt`, where `YYYYMM` the year and month in numeric format is. Intended for auditing only, not accessible from the web. - [[PeterThoeny]] - 07 Dec 1998: Possible to add a category table to a TWiki topic. 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. [[TWikiDocumentation]] has more on setup. The TWiki.Know web uses this category table to set classification, platform and OS version. - [[PeterThoeny]] - 08 Dec 1998: Signature is shown below the text area when editing a topic.

Revision r1.3: 1998/11/10 01:34 by PeterThoeny - [[PeterThoeny]] - 09 Feb 1999: No new topic revision is created if the _same_ person saves a topic again within _one_ hour. - [[PeterThoeny]] - 09 Feb 1999: New text formatting rule for creating `fixed font text` .

Search first in the current web, then in parent data directory. Useful to overload default include text in the data directory by web-specific text, like for example `webcopyright.inc` text. - [[PeterThoeny]] - 21 Jul 1999: Flag `$doRemovePortNumber` in wikicfg.pm to optionally remove the port number from the TWiki URL.

(Previous syntax still supported. Change was done because of inline search syntax) - [[PeterThoeny]] - 11 Feb 2000: New variable `%SCRIPTURLPATH%` / $scriptUrlPath containing the script URL without the domain name. Templates have been changed to use this variable instead of `%SCRIPTURL%` . This is for performance reasons. - [[PeterThoeny]] - 11 Feb 2000: New variable `%SCRIPTSUFFIX%` / $scriptSuffix containing an optional file extension of the TWiki Perl script. Templates have been changed to use this variable. This allows you to rename the Perl script files to have a file extension like for example ".cgi". - [[PeterThoeny]] - 25 Feb 2000: Edit preferences topics to set TWiki variables. There are three level of preferences: Site-level ([[TWikiPreferences]]), web-level ([[WebPreferences]] in each web) and user-level preferences (for each of the [[TWikiUsers]]).
