Overview

Display information about installed plugins.

Usage

The soo_plugin_display tag works as a container or with a form that retrieves most of the txp_plugin fields for the plugin specified in the name attribute. Place any of the other tags (soo_plugin_author, etc.) inside the container or form to display your choice of fields.

If name is left blank (the default), soo_plugin_display will retrieve all plugins (optionally restricted by plugin prefix or status). In this case the plugin code and help will not be retrieved, so soo_plugin_code and soo_plugin_help will not produce output.

The plugin is compatible with soo_plugin_pref, allowing you to adjust some of the default tag attribute values.

Tags

All tags (except for soo_plugin_display) must be in a soo_plugin_display container or form to produce output.

soo_plugin_display

Retrieve a named plugin or a list of plugins; iterate over each plugin with the tag contents or specified form.

<txp:soo_plugin_display form="foo" />    <!-- use with a form -->

<txp:soo_plugin_display>                 <!-- or as a container -->
	...
</txp:soo_plugin_display>

Attributes

• name (plugin name) Plugin to display. If blank (the default), retrieve a list of plugins (list mode)
• form (Txp form name) Form to display output. If empty, container tag required for output. Default is empty (can be changed in prefs).

The remaining attributes are effective only in list mode (i.e., when name is left blank).

• prefix (plugin author prefix) select only plugins with this prefix
• show_inactive (boolean) default “0”, whether to include inactive plugins
• sort (MySQL sort value) default “name asc” (in addition to column names, “size” is also available for sorting)
• wraptag (HTML tag name, without brackets)
• break (HTML tag name, without brackets)
• class (HTML class attribute) applied to wraptag
• html_id (HTML ID attribute) applied to wraptag

soo_plugin_author_uri, soo_plugin_version, soo_plugin_description

No attributes: each simply displays the corresponding field straight from txp_plugin.

<txp:soo_plugin_author_uri />
<txp:soo_plugin_version />
<txp:soo_plugin_description />

soo_plugin_author, soo_plugin_name

As above, but these accept an optional link attribute.

<txp:soo_plugin_author />
<txp:soo_plugin_name />

Attributes

• link (boolean) whether to make output a link to the plugin author’s website, default “1”

soo_plugin_size

Display the plugin’s installed code size in KB (counting 1 character = 1 byte)

<txp:soo_plugin_size />

Attributes

• format (text) default ‘{size} KB’, can be changed in prefs.

The plugin outputs the value of format, first replacing any occurrences of ‘{size}’ with the size in KB.

soo_plugin_help

Display the plugin’s help text.

<txp:soo_plugin_help />

Does not work in list mode (i.e., when soo_plugin_display has a blank name attribute).

Attributes

• strip_style (boolean) whether or not to remove any leading <style> element (%(default)default% “1”, can be changed in prefs)
• strip_title (boolean) whether or not to remove any leading <h1> element (%(default)default% “1”, can be changed in prefs)
• section_id (HTML id value) start display from identified header element, continue till next header of same or lower level
• h_plus (integer) transpose HTML header levels by this amount

strip_style looks for an opening <style> tag at the very start of the Help section. strip_title looks for the first occurence of <h1>. Both do a non-greedy match looking for the closing tag.

With section_id, display begins from the HTML header element with the specified id. Display continues till the next HTML header with the same or lower level (<h2> considered lower than <h3>, for example) or until the end if no such header is found.

h_plus can be helpful when breaking a long help text into several web pages, in conjuction with section_id. For example, h_plus="-2" will transpose all h6 elements to h4, all h5 elements to h3, etc.

soo_plugin_code

Display plugin source code, by default the whole thing, or selected code determined by the function and/or php_class attributes.

<txp:soo_plugin_code />

Does not work in list mode (i.e., when soo_plugin_display has a blank name attribute).

Attributes

• class (html class name) for wrapping <code> and <pre> elements
• html_id (html id name) for wrapping <code> and <pre> elements
• tab_stop (integer) length of tab stop
• function (text) Show only this function. Use in combination with php_class to show only this method.
• php_class (text) Show only this PHP class
• highlight (boolean) whether or not to add syntax highlighting to output. Default “1”, add highlighting (can be changed in prefs).

The remaining attributes are effective only when highlighting is enabled.

• show_line_numbers (text) If set, text to append to each line number. If blank, do not show line numbers. default “:” (can be changed in prefs).
• reindex_lines (integer) With function and/or php_class, renumber lines starting from the value given. Default “0”, do not reindex.

The function/class search isn’t thorough, and is based on my coding style. In the case of a function (outside a class) or class, it simply stops at the first non-indented closing brace (“}”) that occurs after the function or class name. Same for a method (function inside a class) but with the closing brace indented one tab.

Tabs are converted to spaces, to stay aligned with tab stops as set in plugin preferences or the tag_stop attribute.

Highlighting

The code highlighting is based on the PHP highlight_string() function. The style declarations produced by highlight_string() are replaced by class declarations. The important ones:

• php_comment comments
• php_keyword keywords, operators, brackets, semicolons, etc.
• php_default function names (including core PHP functions)
• php_string strings

Everything will be in a span with one of those class names. The whole thing is wrapped in a code element.

If you prefer to use javascript-based highlighting, such as the excellent SyntaxHighlighter, set highlight="0" (or do this in prefs) to get raw (although still HTML-escaped) code output. In this case line numbers will not be added.

Examples

List all active plugins as a table

showing plugin author (as a link to the plugin author’s website) and description

<txp:soo_plugin_display wraptag="table" break="tr">
<td><txp:soo_plugin_name /></td><td><txp:soo_plugin_description /></td>
</txp:soo_plugin_display>

Display plugin help

<txp:soo_plugin_display name="soo_image">
<txp:soo_plugin_help />
</txp:soo_plugin_display>

Display full source code

leaving off the line numbers

<txp:soo_plugin_display name="soo_plugin_pref">
<txp:soo_plugin_code show_line_numbers="" />
</txp:soo_plugin_display>

renumbering the lines, starting from 1

<txp:soo_plugin_display name="soo_txp_obj">
<txp:soo_plugin_code php_class="soo_html" function="tag" reindex_lines="1" />
</txp:soo_plugin_display>
