32.3 Custom Pragmas

You can enable the following features in the editor for regions of code enclosed in comment pragmas:

  • code folding

  • background color

  • receive a read-only notification when editing within the region

To define pragmas for a project, Right click on the project in the Project Explorer view and go to Properties > DVT > Custom Pragmas.

User defined custom pragmas are stored in the .dvt/custom_pragmas.xml file.

custom_pragmas.xml file syntax

 <?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <!DOCTYPE pragmas PUBLIC "-//DVT//custom_pragmas" "custom_pragmas.dtd">
 <pragmas version="1">
   <pragma startPragma="custom pragma start" endPragma="end custom pragma" enabled="TRUE" colorEnabled="TRUE" color="255;0;0" readOnly="TRUE" description="..."/>

Custom pragmas can be shared using Settings Management.

Custom pragmas defined through Settings Management are not editable and are marked with gray color in the project's property page.

For identical pragmas defined in multiple locations, the precedence is:

  • pragmas defined in .dvt (the last defined pragma has the highest priority)

  • pragmas coming from $DVT_USER_SETTINGS/custom_pragmas.xml

  • pragmas coming from $DVT_COMMON_SETTINGS/custom_pragmas.xml

Overridden pragmas are marked with a strike out line.

Note: Two pragmas are identical if they have the same start pragma or end pragma.

Note: A read-only notification does not prevent editing within the region.

Note: You can nest at most 3 custom pragmas.

Note: DVT flags the following incorrect pragma usages:

  • CUSTOM_PRAGMA_NESTING_EXCEEDED: More than 3 nested custom pragmas found


  • CUSTOM_PRAGMA_MISMATCH: Expecting # found #

  • CUSTOM_PRAGMA_NO_END: No matching # end pragma found
