PmWiki: Page Lists

Pm Wiki comes with two directives for generating lists of pages -- (:pagelist:) and (:searchresults:). Both directives are basically the same and each accepts the parameters documented below. The primary difference between the two is that searchresults generates the "Results of search for ..." and "### pages found out of ### searched" messages around the results.

The (:searchbox:) directive generates a search form (input text box) to submit search queries. The markup generally accepts the same parameters as (:pagelist:), which makes it possible to restrict, order and format searchresults in the same ways that are described below for a (:pagelist:). For more information about the (:searchbox:) directive, and the ways in which it differs from a (:pagelist:), skip to the section below.

Basic syntax

without any arguments shows a bulleted list of all pages, as links, ordered alphabetically and in groups.
shows a pagelist according to the parameters supplied. Parameters are optional.

Parameters

Any argument supplied within (:pagelist:) that isn't in the form 'key=value' is treated as text that either must (or must not) exist in the page text.

The minus sign (-) can be used to indicate things that should be excluded. Thus

(:pagelist trail=PmWiki.DocumentationIndex list=normal apple -pie:)

lists all "normal" pages listed in the Documentation Index trail that contain the word "apple" but not "pie".

With page text variables

You can also use page text variables as a key to list pages according to the existence of a page text variable. Eg :

(:pagelist $:pagetextvar=avalue:)

lists pages having $:pagetextvar set to avalue.
Minus sign (-), wildcards (?*) and a comma separated list of values also works when specifying a selection based on pagetextvariables. Eg :

(:pagelist $:apagetextvar=t*,-test:)

lists pages having $:apagetextvar like 't*' but not 'test'.
Examples:

PTV is set (is not empty):(:pagelist $:MyPageTextVariable=- :)
PTV is empty or not set:
 (ie, is not set to one char followed by 0 or more chars)
(:pagelist $:MyPageTextVariable=-?* :)
PTV is not VALUE:(:pagelist $:MyPageTextVariable=-VALUE :)
PTV is set and not YES:(:pagelist $:MyPageTextVariable=?*,-YES :)

Be aware that if using (:pagelist $:MyPTV=$:YourPTV :) PT Vs? include Pm Wiki formatting, so you may not get the matches you expect. Currently the only way around this is to use wild cards, so if the formatting is embedded you may be out of luck.

With page variables (PV)

Page variables can be used within pagelists in the same way as page text variables. See Page Text Variables above for more details. Simply use $var instead of $:var.

group= and name=

The "group=" and "name=" parameters limit results to pages in a specific group or with a specific name:

All pages in the Pmwiki group: (:pagelist group=PmWiki :)
All pages except those in the Pm Wiki or Site groups: (:pagelist group=-PmWiki,-Site :)
All Recent Changes pages (:pagelist name=RecentChanges :)
All pages except Recent Changes (:pagelist name=-RecentChanges :)

Wildcards

Name and group parameters can contain wildcard characters that display only pages matching a given pattern:

Examples:

All pages in any group beginning with "Pm Wiki" (:pagelist group=PmWiki* :)
All pages in any group beginning with "Pm Wiki", except for Chinese (:pagelist group=PmWiki*,-PmWikiZh :)
All pages in the Pm Cal? group with names starting with "2005": (:pagelist name=PmCal.2005* :)
All Cookbooks with names beginning with a A and a B letter
note the different separators used for the same result
(:pagelist group=Cookbook name=A*,B*   :)
(:pagelist group=Cookbook name="A* B*" :)
(:pagelist group=Cookbook name=[AB]*   :)
(:pagelist group=Cookbook, name=[AB]*   :)

If you want to use multiples conditions in name you need to use quotes or commas to delimit the string.

trail=

The "trail=" option obtains the list of pages to be displayed from a WikiTrail:

(:pagelist trail=PmWiki.DocumentationIndex order=-time:)
(:pagelist trail=RecentChanges count=5:)

list=

The "list=" option allows a search to include or exclude pages according to predefined patterns set by the administrator.

fmt=

The "fmt=" option determines how the resulting list should be displayed. Pm Wiki predefines several formats:

These formats are defined by page list templates, which can be customized.

This format is not predefined by a page list template:

link=

The "link=" option implements "backlinks" -- i.e., it returns a list of pages with a link to the target. It's especially useful for category pages and finding related pages.

(:pagelist link=PmWiki.DocumentationIndex:)
(:pagelist link={$FullName}:)
(:pagelist link=Category.Skins:)

count=

The "count=" option provides the ability to

A simple bullet list of ten most recently modified pages

(:pagelist trail=Site.AllRecentChanges count=10 fmt=#simple:)

Display the first ten pages of a list

count=10 # display the first ten pages of list

Negative numbers specify pages to be displayed from the end of the list:

count=-10 # display last ten pages of list

Ranges may be specified using '..', thus:
count=1..10       # first ten pages of list
count=5..10       # 5th through 10th pages of list
Negative numbers in ranges count from the end of the list:

count=-10..-5 # 10th from end, 9th from end, ..., 5th from end

Omitting the start or end of the range uses the start or end of the list:
count=10..        # skip first ten pages
count=..10        # 1st through 10th page of list
count=-10..       # last ten pages of list
count=..-10       # all but the last nine pages
Ranges can be reversed, indicating that the order of pages in the output should likewise be reversed:
count=5..10       # 5th through 10th pages of list
count=10..5       # same as 5..10 but in reverse sequence
count=-1..1       # all pages in reverse sequence
"Reverse sequence" here refers to the sequence after any sorting has taken place. Therefore the three directives to the right are equivalent:
(:pagelist order=-name count=10:)
(:pagelist order=-name count=1..10:)
(:pagelist order=name count=-1..-10:) 

wrap=

The "wrap" option has the values, none and inline.

With "wrap=inline" and "wrap=none", the output from pagelist (markup or HTML) is directly embedded in a page's markup without any surrounding <div> class=...</div> tags.

With "wrap=inline", any surrounding <ul> is continued. Without "wrap=inline", the HTML output starts a new <ul>. This is important if you want to get a second level <ul> produced by the page list since starting a new <ul> with "**" doesn't yield a second level <ul> but <dl><dd><ul>...

"wrap=inline" likely has other effects since it suppresses the call to $FPLTemplateMarkupFunction (being Markup To HTML? by default).

class=

By default, a pagelist has the 'fpltemplate' class. The 'bygroup', 'simple', 'group' and 'title' page list formats have specific class names fplbygroup, fplsimple etc. You can set any class using the class= parameter or by setting the $FPLFormatOpt array.

passwd=

The "passwd" option returns only those pages that have some sort of password attribute on them.

if=

The "if" option allows a condition to be specified as part of the pagelist processing, rather than from within the page list template. Only those pages for which the condition is true are retrieved. Anything that could go within an (:if ...:) can be used as a condition. For example

  (:pagelist if="date {(ftime %GW%V {*$Name})} {=$Name}" :)

returns all of the pages where the name is in the same week as that of the current page.

If any arguments within the quotes could contain a space they must be quoted:

  (:pagelist if="date 2009-01-01..2009-12-31 '{=$:Mydate}'" :)

order=

The "order=" option allows the pages in the list to be sorted according to different criteria. Use a minus sign to indicate a reverse sort. Multiple sorting criteria can be specified using a comma, and you can create your own custom pagelist sort order:

Also, the order= option allows custom ordering functions to be written.

cache=0

Pagelist has the capability to cache lists which greatly speeds up processing (when $PageListCacheDir is set). Every once in a while this caching can result in undesired results. Specifying cache=0 disables caching.

Specifying variables as parameters

You can also specify variable values inline with the pagelist statement, and refer to the variables in the template using the {$$variable1} format:

(:pagelist fmt=#pagelist variable1="value" variable2="value2":)

This assumes that a site has $EnableRelativePageVars enabled, which is recommended in Pm Wiki 2.2.0 -- but disabled by default to help people upgrading from 2.1.x.

For example, in the template:

>>comment<<
[[#tvars]]
(:template default count=1 ParamName=Simon:)
Hi, {$$ParamName}, how are you today?
[[#tvarsend]]
>><<

(:template default count=1 Param Name?=Simon:) Hi, {$$ParamName}, how are you today?

This gives:

(:pagelist fmt=#tvars ParamName="Sam":)

(:pagelist fmt=#tvars
ParamName="Sally":)

(:pagelist fmt=#tvars:)

Hi, Sam, how are you today?

Hi, Sally, how are you today?

Hi, Simon, how are you today?

See also $EnableUndefinedTemplateVars.

Examples

Include the contents of a random page from the Banners group:

(:pagelist group=Banners order=random count=1 fmt=#include list=normal:)

Display a simple list of the last ten recently changed pages:

(:pagelist trail=Site.AllRecentChanges count=10 fmt=#simple:)

Display the "top twenty" biggest cookbook pages:

(:pagelist group=Cookbook order=-size count=20 :)

The Searchbox Directive

The (:searchbox:) directive generally accepts the same parameters as (:pagelist:) and (:input text:) directives:

The Searchresults directive

The (:searchresults:) directive generally accepts the same parameters as (:pagelist:) and (:input text:) directives:

request=1 req=1

(:searchresults:) without the introductory line that says "Results of search for..."
