BlogPlugin

NOTE: This blog plugin is no longer maintained. We recommend to use the BlogAddOn application.

This is the supplemental plugin for the BlogUp TWikiApplication. It bundles some of the features found in common blogging applications that are very hard or even impossible to implement using TWikiML. Note, that most of the tags are tightly related to the data model of BlogUp, i.e. it relies on its TopicType and TWikiForm definitions.

Shortcut: want to create a blog ... use the BlogFactory.

Syntax Rules

CITEBLOG

Format a link to another BlogEntry displaying its headline and date.

Syntax:

%CITEBLOG{"<topic>"}%
"<topic>" name of a BlogEntry topic, e.g. BlogEntry0

Example:

%CITEBLOG{"_BlogPlugin.BlogEntry0"}%

%CITEBLOG{"_BlogPlugin.BlogEntry0"}%

COUNTCOMMENTS

Count the BlogComments that refer to a given topic recursively, that is the number of BlogComment topics that refer to a given BlogEntry and each BlogComment referring to the BlogComment found so far. Reference is expressed by the BlogRef formfield in the BlogCommentForm.

Syntax:

%COUNTCOMMENTS{"<topic>" ... }%
"<topic>" name of a BlogEntry or BlogComment topic, e.g. BlogEntry0
web="..." web where to search for references; defaults to the web specified as part of the "topic" parameter or the current one
format="..." format string used to display the count; the variable $count is replaced by the calculated references; defaults to "$count"
single="..." format string used to display a single hit; defaults to the "format" value (see above)
null="..." format string used to display a zero hit; defaults to "0"
hidenull="on,off" if set to "on" nohting is displayed if no references where found; defaults to "off"
offset="..." add an "offset" to the computed number of hits; so if offset="9" and 11 references where found the $count is set to 20

Following variables are expanded in format strings:

  • $percnt: % sign
  • $dollar: $ sign
  • $n: newline
  • $t: tab
  • $nop: "empty string"
  • $count: the calculated number of references (plus an optional offset)

PREVDOC, NEXTDOC

Display the previous/next topic in an ordered set. These tags can be used to establish a navigation within a set of related topics paging to the preceding or succeeding one. A set of related topics is defined using a "where" and an "order" clause which the given topic is supposed to be part of.

Syntax:

%PREVDOC{"<topic" where="..." ...}%, %NEXTDOC{"<topic" where="..." ...}%
"<topic>" topic which we search the predecessor/successor of
web="..." web where to search for related topics; defaults to the web given with the <topic> parameter or the current one
where="..." search clause, see documentation of the DBCacheContrib
order="..." document property used to sort the hit set; defaults to "created"
reverse="on,off" if set to on the sorting will be reversed, that is the logic of PREV and NEXT is inverted

RECENTCOMMENTS

Display an ordered list of most recent BlogComments, grouped by the referred BlogEntry.

Syntax:

%RECENTCOMMENTS{"<format>" ...}%
"<format>" format string used to display the hit results; each hit is displayed using the given format
header="..." format string to prepended to the list of hits being displayed
footer="..." format string to appended to the list of hits being displayed
separator="..." format string used to separate hits; defaults top "$n"; the special separator "none" disables separation
limit="..." restrict the number of hits being displayed; defaults to "-1" which means unlimited
age="..." restrict the age of comments being displayed; values must be given in epoch seconds, e.g. 5184000 being ca. 2 months; defaults to "0" which means unlimited
category="..." pattern that limits comments to those whose BlogEntries match the SubjectCategory; defaults to ".*"
author="..." pattern that limits comments to those on BlogEntries from the given author defaults to ".*"

(Each BlogEntry that is found given the above search parameters and limits is called a hit.)

Following variables are expanded in format strings:

  • $percnt: % sign
  • $dollar: $ sign
  • $n: newline
  • $t: tab
  • $nop: "empty string"
  • $count: the number of comments on the given BlogEntry
  • $topic: the topic name of the referring BlogEntry, e.g. BlogEntry0
  • $web: the web where the hit was found
  • $headline: the headline of the referring BlogEntry
  • $commenter: a list of links to the comments in the format [[BlogEntry0#BlogComment1][<author>]],... (author: name of commenter)
  • $date: date of the most recent comment on the current hit.

See also the interface TopicFunction "RenderRecentComments".

RELATEDENTRIES

Display a list of BlogEntries related to a given one. The Relationship is manually encoded in the data model using the "Related" formfield. The relation is computed transitively and reflexively ('til a configurable depth). That is, two BlogEntries A and B are related if A points to B or vice versa or A and B are connected by a series of related postings C1,...CN, where A is related to C1 and B CN is related to B.

Syntax:

%RELATEDENTRIES{"<topic>" ...}%
"<topic>" topic name of a BlogEntry related once are search for
web="..." web where to search for related topics; defaults to the web given with the <topic> parameter or the current one
format="..." format string to display a hit; defaults to "$topic"
header="..." format string to prepended to the list of hits
footer="..." format string to appended to the list of hits
separator="..." format string used to separate hits; defaults to "$n"; the special separator "none" disables separation
depth="..." depth of recursion (the number of hops from posting A to posting B); defaults to "2";

Note, that large "depth" values will very soon include your complete blog archive. The hit set also depends on the amount of direct relationships that you add to your BlogEntries. So either use a low "depth" value and add more direct relations based on your own judgment, or just specify one related entry and use a "depth" value of up to 3 for good results.

Following variables are expanded in format strings:

  • $percnt: % sign
  • $dollar: $ sign
  • $n: newline
  • $t: tab
  • $topic: topic name of a hit
  • $web: web name where the hit was found
  • $depth: distance to the given <topic> (depth in which this topic was found)
  • $headline: headline of the related BlogEntry

The relatedness feature here is a very naïve and purely manual one. We'd like to semi-automate this task using some automatic classificator on document similarities. Making use of weights following links is an option too to improve the hit set quality.

And send me a patch if you've coded that into TWiki ;).
