Scripting: text editing

These are scripts which deal mostly with editing the text of nodes.

Some of them are also available in the editgoodies addon.

Feel free to add your own scripts here. If you give script a name using wiki text like

<groovy name="yourScriptName">
 your script
</syntaxhighlight>

an extra download button is created for it, and it can be downloaded directly from this page.

For larger scripts there is a special git repository [1].

Transpose the two characters around the cursor (for bad typists)

Once this script is downloaded and placed in the script directory, it should be bound to a keystroke so that it can be called without moving from the keyboard. It is now also available as part of the Edit Goodies addon, as is the script below, to change case. That's much the easiest way to install it. This version should be considered a purely instructional example.

<groovy name="transpose">

 // @ExecutionModes({ON_SINGLE_NODE}) 
 // first we import the Java libraries needed 
 // to access and manipulate the text of a node
 import java.awt.KeyboardFocusManager 
 import javax.swing.JEditorPane 
 // Then wrap the action in a "try/catch" block so that it fails gracefully
 // though the record is written to a largely inaccessible log file, and should be displayed better
 try { 
    def focusOwner = KeyboardFocusManager.currentKeyboardFocusManager.focusOwner 
    // these two lines check that the cursor is inside a node being actively edited
    if (focusOwner instanceof JEditorPane) { 
        JEditorPane editor = focusOwner 
        // next, find the cursor position and save it in a variable
        cursor = editor.caretPosition - 1 
        // Get a copy of the node text with all the html markup stripped out
        def oldstr = htmlUtils.htmlToPlain(editor.text)
       // Make a new string with the letters around the cursor changed
        def newstr = oldstr.substring(0, cursor-1) + oldstr[cursor] + oldstr[cursor-1] + oldstr.substring(cursor+1) 
        // And write it back into the node
        editor.text = newstr 
        // finally, put the cursor back where it was
        editor.caretPosition = cursor + 1 
    } 
    else { 
        c.statusInfo = 'cannot transpose: inline editor not active' 
    } 
 } 
 catch (Exception e) { 
   logger.severe('cannot transpose', e) 
 }

Change case of words, and sort bAD CApitalisation

This script, like the one above, is part of the edit goodies addon, available from the support site. If used from here, it should be bound to a key

Clean screen editor

A toggle script for when you want to concentrate: will either centre the selected node, hide all others, and darken the background, or switch back to the normal bright, and possibly cluttered, view.

<groovy name="Cleanscreen">

 // @ExecutionModes({ON_SINGLE_NODE})

 import org.freeplane.features.styles.MapStyleModel
 def setBackgroundColor(Color actionColor) {
   Controller controller = Controller.getCurrentController();
   MapStyle mapStyle = (MapStyle) controller.getModeController().getExtension(MapStyle.class);
   MapStyleModel model = (MapStyleModel) mapStyle.getMapHook();
   mapStyle.setBackgroundColor(model, actionColor);
 }

 def setBackgroundColorCode(String rgbString) {
   setBackgroundColor(ColorUtils.stringToColor(rgbString));
 }

 // note Groovy gotcha in the next line -- if "paleblue" 
 // is defined as a colour explicitly, as in

 // the script breaks, because variables defined in this way are not accessible inside blocks

Inserts an inline image into node text or details

This script asks for an image file for inclusion as an inline graphics either into node details or node text. Plain texts will be converted to HTML. Thanks to Q for asking for this feature.

Note: This script is here just as an example for coding. If you just want to use it use the Insert Inline Image Add-On instead.

Requires at least Freeplane 1.2.7

Simple plain text word count using scripts

This script will take the selected node(s), iterate down through subnodes, and count plain text. Notes, attributes, icons are not counted.

<groovy name="countWords">

 // @ExecutionModes({ON_SINGLE_NODE})
 // Initial version: wordCount.groovy by User:cybaker
 // Adapted for Freeplane by User:Boercher
 // This script goes through all selected nodes and their subnodes and
 // counts the number of plain text words, not including notes. Words
 // are delimited by a any white space character.
 // Message box for reporting added by User:seatrout
 //
 // Usage: Select node(s). Run script once.

 import java.text.NumberFormat;

 def nodes = new HashSet()
 c.selecteds.each{ nodes.addAll(it.find{true}) }

 def result = nodes.sum(0){ it.plainTextContent.split("\\s+").length }
 ui.informationMessage(ui.frame, NumberFormat.getInstance().format(result)+ " Words in selected node and children", "Word Count")

Delete line breaks

 Replace line breaks in the node text by space characters.

 <groovy name="deleteLineBreaks">
 
 // @ExecutionModes({ON_SELECTED_NODE})
 node.text = node.text.replaceAll('\\s*\n\\s*', ' ')
 

</syntaxhighlight>

Note statistics

This script prints note statistics to the status bar no matter if the note editor panel is opened or not. Although not strictly an editing script this one shows how to access the note editor panel.

<groovy name="noteStatistics"> // @ExecutionModes({ON_SINGLE_NODE})

import org.freeplane.features.note.NoteController

def noteTextFromViewer = NoteController.controller.noteViewerComponent?.documentText def noteText = noteTextFromViewer ? htmlUtils.htmlToPlain(noteTextFromViewer) : node.note?.to?.plain if (noteText) { def wordCount = noteText.split('\\W+').length c.statusInfo = "note: ${wordCount} words, ${noteText.length()} characters" } else { c.statusInfo = "no note" } </syntaxhighlight>
