An edit mode for Matlab. You will also need to add an appropriate entry to the catalog file -- see the jEdit help on writing edit modes for more information. Matlab files usually have the suffix ".m" (objective-C coders may like to note the clash).

Syntax highlighting for IBM MQSeries script (MQSC), accurate for WebSphere MQ v5.2

Enables highliting the attributes inside XML tags in a diffrent color than the markup. Update the $Jedit/modes/xml.xml file

Edit mode for HSQLDB's SQL dialect

dot can be used for editing files in the dot-language (surprise, surprise) of the graphviz-package of at&t (see http://www.graphviz.org)

This is another HTML Mode modification , that distinct tags, attributes, literals, inlines CSS, Javascript and VBScript

An ABAP edit mode. I found one for GVIM but as I use Jedit now this is really essential for my job.

Adds explicit folds around imports, static initializers, methods, constructors and inner classes in a Java buffer. The opening folds are appropriately labelled. methods of anonymous inner classes, etc. are also folded. The only known limitation is the macro doesn't pick up methods, constructors & inner classes that are package protected (i.e. have no public|protected|private declaration). This is basically a macro version of the LazyFolds plugin (the plugin can work for modes other than Java).

4 simple macros that run the A,B,C,D targets in AntHelper but also force the AntFarm dockable window to stay closed. These are ideal for binding to shortcuts enabling you to work quickly without having a dockable you don't need to use popping up all the time.

2 macros that allow lines to be selected from a buffer based on whether they match (or do not match for the 2nd macro) a regular expression. The selected lines are placed in a new jEdit buffer. This is ideal for browsing large log files where you are looking for certain entries, etc.

6 macros that can convert a selection between different numeric formats; binary, decimal, hex and Roman numerals.

Expands/Collapses explicit folds based on them being preceded by a + or - ( +{{{ or -{{{ ). This lets you create a default expanded/collapsed state for each fold.

Changes some GUI properties to be more compact, with less wasted space. it'd shouldn't be hard to adjust this script to taste.

An Edit mode for ant build files. It must be in the jEdit system directory in order to override the normal xml mode when needed.

Converts the selected text to its hexidecimal equivalent

Converts the selected text from hexidecimal to ascii text.

An HTML edit mode which highlights recognized tags, attributes, and values, and delegates to PHP where appropriate

Converts all selected characters to Java-style unicode escapes (e.g. \u0000) unless the selection is a sequence of unicode escapes in which case they are converted back to characters.

A template that can insert a GNU Public Licence header in a buffer using comment symbols and buffer settings appropriate to the buffer.

An Ant task that can reload a jEdit 4.2 plugin. This task can be used in plugin build.xml files to save repeatedly opening & closing the Plugin Manager. This version is aware of dependent plugins and by default also reloads them. The task can be used from within jEdit (for example, by using AntFarm), but is safe to include in build.xml files that may be used elsewhere (it will simply do nothing if jEdit is not available).
