Scripts collection

From Freeplane - free mind mapping and knowledge management software
Revision as of 23:47, 28 July 2011 by Boercher (talk | contribs) (→‎Set up a logger)

The first version of this Scripting article mainly consists/consisted of a port of the FreeMind script collection. Some of those scripts got a general rewrite; - escpecially those that were marked buggy or even broken. But I took the freedom to (hopefully) improve every script where it made sense. With one exception ("Sum up all subnodes...", a very long script) I have ported all scripts from the FreeMind page, regardless of how useful I found them since I believe that you will be able to learn from all of them.

Unfortunately I do not know some authors of the scripts, so I can't give them proper reference. Please help identify them.

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

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

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

For larger scripts there is a special Bazaar repository. Inspect it at contrib/groovy or get it via 

 bzr branch bzr://freeplane.bzr.sourceforge.net/bzrroot/freeplane/contrib/groovy  [read only]
 bzr+ssh://USERNAME@freeplane.bzr.sourceforge.net/bzrroot/freeplane/contrib/groovy/ [developers only]


A node with the last modification date of the map

This script sets the text of the status bar to the last modification timestamp of the whole map.

<groovy name="lastModificationDate"> // @ExecutionModes({ON_SELECTED_NODE}) // find all nodes, collect their lastModifiedAt date and get the latest def lastModifiedAt = c.find{true}.collect{it.lastModifiedAt}.max() def f = new java.text.SimpleDateFormat("yyyy-MM-dd hh:mm:ss") c.statusInfo = "The map was last modified at: " + f.format(lastModifiedAt) </groovy>

Author: User:Boercher

Prepend the modified date at the beginning of the node text

This is a port of the respective script on the FreemindPage. Note that node.lastModifiedAt requires Freeplane 1.0.40 or later

<groovy> =new java.text.SimpleDateFormat("M/d/yyyy").format(node.lastModifiedAt) + 

   " " + node.text

// @ExecutionModes({ON_SELECTED_NODE}) </groovy>

Add up attribute values of subnodes.

This script adds up the "AMOUNT" attributes of all child nodes of a node and sets the "AMOUNT" attribute of the selected node to the sum.

<groovy name="sumAttributeValues"> import java.text.NumberFormat;

// global binding attrib = "AMOUNT"

def get(node) { 

   def text = node.getAttributes().get(attrib)
   if (text != null && text.isDouble())
       return text.toDouble()
   return 0

} node.getAttributes().set(attrib, NumberFormat.getInstance().format(node.children.sum{get(it)})) // @ExecutionModes({ON_SELECTED_NODE}) </groovy>

With Freeplane 1.2 series and above this script boils down to two lines: <groovy name="sumAttributeValues"> node['VALUE'] = java.text.NumberFormat.getInstance().format(children.sum{it['VALUE'].num0}) // @ExecutionModes({ON_SELECTED_NODE}) </groovy>

The following script does the same but recursively, i.e. called for the root node it updates the complete map so that each parent node has the "AMOUNT" attribute set to the sum of all children, grandchildren and so on.

<groovy name="sumAttributeValuesRecursively"> import java.text.NumberFormat;

// global binding attrib = "AMOUNT"

def get(node) { 

   def text = node.getAttributes().get(attrib)
   if (text != null && text.isDouble())
       return text.toDouble()
   return 0

}

def set(node, amount) { 

   node.getAttributes().set(attrib, NumberFormat.getInstance().format(amount))

}

def setAndReturnSum(node) { 

   if (node.isLeaf()) {
       return get(node)
   }
   else {
       def total = node.children.sum{ setAndReturnSum(it) }
       set(node, total)
       return total
   }

}

setAndReturnSum(node) // @ExecutionModes({ON_SELECTED_NODE}) </groovy>

Set the color for all children

This is an example of iteration over child nodes.

<groovy name="blueChildren"> node.children.each{ it.style.nodeTextColor = java.awt.Color.BLUE } // @ExecutionModes({ON_SELECTED_NODE, ON_SELECTED_NODE_RECURSIVELY}) </groovy>


Sort child nodes alphabetically or by length

<groovy name="sortChildren"> def sorted = new ArrayList(node.children).sort{ it.text } def i = 0 sorted.each { 

   it.moveTo(node, i++)

} // @ExecutionModes({ON_SELECTED_NODE, ON_SELECTED_NODE_RECURSIVELY}) </groovy>

To sort by length: Change "it.text" to "it.text.length()".

To reverse either of these sorts: Add a minus sign before "it", i.e. "-it.text.length()".

Set up a logger

The following code makes use of the application logger provided by LogTool. Note that name and package of this class has changed since version 1.2.

<groovy> import org.freeplane.core.util.LogTool; LogTool.info(" ******* Logger set up for script"); </groovy> In Freeplane 1.2 this simply reads (no import, no static access): <groovy> logger.info(" ******* Logger in 1.2"); </groovy>

Export to BibTeX

A working script for creating BibTeX files from a special formatted mindmap. A BibTeX node has an attribute "bibtex" with the kind of article as value (e.g. "article", "note"). Bibtex entry properties are given as attributes as well. Unfortunately it's currently not possible to write the attribute names other than in lower case.

The resulting BibTeX file is shown in a popup window that supports scrolling and cut 'n paste.

<groovy name="exportToBiBTeX"> import javax.swing.*; import org.freeplane.core.ui.components.UITools;

// for cut 'n paste: def showDialog(String text) { 

   def dialog = new JDialog(UITools.getFrame())
   dialog.setSize(350, 450)
   dialog.setLocationRelativeTo(UITools.getFrame())
   dialog.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE)
   dialog.add(new JScrollPane(new JTextArea(text)))
   UITools.addEscapeActionToDialog(dialog)
   dialog.setVisible(true)

}

def all_tags = ['address', 'author', 'booktitle', 'chapter', 'edition', 'editor', 

   'howpublished', 'institution', 'isbn', 'journal', 'month', 'note', 'number',
   'organization', 'pages', 'publisher', 'school', 'series', 'title', 'type',
   'volume', 'year']

def processAttribute(attr, attr_name) { 

   return (attr.findAttribute(attr_name) != -1) ?
       attr_name + " = \"" + attr.get(attr_name) + "\"" :
       null

}

def process(type, attr, index) { 

   // note: there's no getAttributeNames() yet so
   //  - we can not iterate over *existing* attributes
   //  - we can not match case insensitive
   // -> should be fixed ASAP
   def tags = all_tags.collect { processAttribute(attr, it) }
   // compact: erase nulls
   return "@" + type + "{${index.toString()}, \n  " +
       tags.grep { !it.is(null) }.join(",\n  ") +
       '\n}\n\n'

}

def getChildrenRecursive(node) { 

   if (node.isLeaf()) {
       return [node];
   }
   else {
       // father and sons
       return [node] + node.children.collect{ getChildrenRecursive(it) }.flatten();
   }

}

index = 1; // merge everything into one string def result = getChildrenRecursive(node).sum { 

   def attr = it.attributes;
   // valid values would be: article, book, booklet, conference, inbook,
   // incollection, inproceedings, manual, mastersthesis, misc, phdthesis,
   // proceedings, techreport, unpublished
   if (attr.get('bibtex'))
       return process(attr.get('bibtex'), attr, index++);
   else
       return ;

}; showDialog(result) </groovy>

Use the following script to create a map for testing purposes. It adds some "BibTeX nodes" to selected nodes: <groovy name="prepareBiBTeXTestMap"> i = 1 def makeBibEntry(node, type, tags) { 

   def child = node.createChild()
   child.attributes.set('bibtex', type);
   tags.each {
       child.attributes.set(it, it + "_" + i++)
   }

}

makeBibEntry(node, 'article', ['author', 'title', 'journal', 'year', 'url']) makeBibEntry(node, 'techreport', ['author', 'title', 'institution', 'year']) makeBibEntry(node, 'misc', ['author', 'url']) makeBibEntry(node, 'proceedings', ['author', 'title', 'year', 'url']) </groovy>

Sum up all subnodes recursively for attributes

Did not try to port this script due to its length. Tell me if you would like to see it here.


Output A Map to CSV

For export to a spreadsheet for inclusion in a larger project plan. The following script creates CSV output from a mindmap and shows it in a dialog window for cut 'n paste. <groovy name="exportToCSV"> import javax.swing.*; import org.freeplane.core.ui.components.UITools;

// for cut 'n paste: def showDialog(String text) { 

   def dialog = new JDialog(UITools.getFrame())
   dialog.setSize(350, 450)
   dialog.setLocationRelativeTo(UITools.getFrame())
   dialog.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE)
   dialog.add(new JScrollPane(new JTextArea(text)))
   UITools.addEscapeActionToDialog(dialog)
   dialog.setVisible(true)

}

def process(thisNode, childPosition) { 

   def result = childPosition, thisNode.text
   thisNode.children.each {
       result += process(it, childPosition + 1)
   }
   return result

}

def result = process(node, 0); showDialog(result.collect{ "," * it[0] + it[1] }.join("\n")) </groovy>

Output A Map to CSV Part 2

The second iteration of the export to CSV script allows different item types to be denoted by icons (here the number icons ("1", "2", ...) which then get mapped to attribute values. That way I can do things like estimate the complexity of a task by adding a number icon and then have that mapped to text like "Very Complex" in my CSV file. Here is the code:

<groovy name="exportToCSV_2"> import org.freeplane.core.util.HtmlTools

class TreeWalker { 

   def rootNode;
   def minFontSize;
   private iconMappings = [:]
   private attributeMappings = [:]
   private attributeNames = []

   def visit(thisNode, childPosition) {
       def attributes = [:]
       def nodeName = HtmlTools.htmlToPlain(thisNode.getPlainTextContent())
       def nodeLevel = thisNode.getNodeLevel(true)
       thisNode.icons.icons.each { iconName ->
           if (iconMappings[iconName]) {
               def attributeName = iconMappings[iconName]
               def attributeValue = attributeMappings[attributeName][iconName]
               attributes[attributeName] = attributeValue
           }
       }
       def attributeString = ""
       attributeNames.each {
           attributeString += ",${attributes[it]?attributes[it]:}"
       }
       def nodeType = ""
       if (new Integer(thisNode.style.font.size) < minFontSize) {
           nodeType = "Note"
       } else {
           if (attributes.Complexity) {
               nodeType = "Widget"
           } else {
               nodeType = "Heading"
           }
       }

       println "$nodeType,$nodeLevel,$childPosition$attributeString,\"$nodeName\""
       def i = 0
       if (thisNode.children) {
           thisNode.children.each {
               i++
               visit(it, i)
           }
       }
   }

   def walk() {
       visit(rootNode, 0)
   }

   /**
    * Add a set of mappings from icon names to values for a given attribute
    */
   def addAttributeMapping(attributeName, mappings) {
       attributeMappings[attributeName] = mappings;
       mappings.each {
           iconMappings[it.key] = attributeName;
       }
       attributeNames << attributeName;
   }

}

def walker = new TreeWalker(rootNode:node, minFontSize:12); walker.addAttributeMapping("Complexity", 

   [   "full-1":"Very Simple",
       "full-2":"Simple",
       "full-3":"Medium",

Daves massivly cheezy Api Generator

If you are lazy (like me) and don't wan't to look through the source code to find the api for the node and c variables, use this to make a somewhat cheezy mindmap/api

<groovy name="apiGenerator"> // @ExecutionModes({ON_SINGLE_NODE}) def lastSection(string){ 

   if (string == null)
       return null
   String[] p = string.split("\\.");
   return p[p.size()-1];

}

def removeModifiers(String[] parts) { 

   def result = parts.toList()
   result.remove("final")
   result.remove("abstract")
   return result

}

def newChildNode(node, method){ 

   def apiNode    = node.createChild(0);
   def returnType = apiNode.createChild(0);
   def iProto     = apiNode.createChild(1);

   def text = method.toString();
   List parts = removeModifiers(text.split(" "));

   StringBuilder sb = new StringBuilder();
   sb.append(parts[0]);
   sb.append(" ");

   sb.append(lastSection(parts[1]));

   returnType.setText(parts[1].replace('Proxy$', ));

   sb.append(" ");
   sb.append(method.getName());
   sb.append("(");

   def Class[] parms = method.getParameterTypes();
   def protoTxt = new StringBuffer();
   if(parms.size() >0){
       for(i in 0..parms.size()-1){
           protoTxt.append(parms[i].toString());
           sb.append(lastSection(parms[i].toString()));
           if(i<parms.size()-1){
               protoTxt.append("\n");
               sb.append(",");
           }
       }
   }
   else{
       protoTxt.append("*none*");
   }
   sb.append(")");
   apiNode.text = sb.toString().replace('Proxy$', );
   apiNode.folded = true;
   iProto.text = protoTxt.toString().replace('Proxy$', );

}

def makeApi(node, clazz) { 

   def child = node.createChild()
   child.text = clazz.name.replace('Proxy$', )
   def methods = clazz.getMethods()
   for(i in 0..<methods.size()){

Simple bookmark implementation using scripts

This is a rudimentary implementation of bookmarks. If set up as described below you can use a self chosen key combination to memorize the currently selected node and return to it at any later time using another key combination. A third key combination takes you to the subtree containing the recently stored bookmark and allows you to rename it. This is the basis of managing and accessing multiple named bookmarks.

Step 1: put these three scripts in your ~/.freeplane/scripts directory (or whereever you tell freeplane to look for groovy scripts)

<groovy name="setBookmark"> // @CacheScriptContent(true) def bookmarksNode if((dummyList = c.find{ it.text.equals("Bookmarks")}).isEmpty()) { 

   (bookmarksNode = node.getMap().getRootNode().createChild()).setText("Bookmarks")

} else { 

   bookmarksNode=dummyList.get(0)

}

if((dummyList = bookmarksNode.find{ it.text.equals("recent")}).isEmpty()) { 

   (recentBookmarkNode = bookmarksNode.createChild()).setText("recent")

} else { 

   recentBookmarkNode=dummyList.get(0)

}

recentBookmarkNode.getLink().set("#"+c.getSelected().getNodeID()) </groovy>

<groovy name="gotoRecentBookmark"> // @CacheScriptContent(true) def dummyList1 def dummyList2 if(!(dummyList1 = c.find{ it.text.equals("Bookmarks")}).isEmpty()) { if(!(dummyList2 = dummyList1.get(0).find{ it.text.equals("recent")}).isEmpty()) { if((linkString=dummyList2.get(0).getLink().get())!=null){ c.select(node.getMap().node(linkString.substring(1))) } } } </groovy>

<groovy name="gotoBookmarks"> // @CacheScriptContent(true) def dummyList1 def dummyList2 if(!(dummyList1 = c.find{ it.text.equals("Bookmarks")}).isEmpty()) { if(!(dummyList2=dummyList1.get(0).getChildren()).isEmpty()){ c.select(dummyList2.get(0)) } } </groovy>

Step 2: (Re)start freeplane. Choose menu Tools/Scripts/SetBookmark and Ctrl-click on "Execute SetBookmark on one selected node". You are asked to choose a new shortcut key (combination). Do similar for the gotoRecentBookmark.groovy and gotoBookmarks.groovy scripts. Voilà.

Once setBookmark.groovy is executed, a child node named "Bookmark" will be added to the map root node. In the beginning it has one child named "recent". The latter has a local hyperlink pointing to the currently selected node. Executing gotoRecentBookmark.groovy simply follows this link. Everytime you execute setBookmark.groovy this link will be overwritten. You can rename the "recent" node to conserve the link. This is the basis of managing multiple bookmarks. For convenience, executing gotoBookmarks.groovy will take you to the first child of the "Bookmarks" node to quickly access your "Bookmark manager" subtree. From here you can manually follow the links as usual, pressing 'Ctrl-Enter' or klicking the arrow icon. Please feel free to improve the scripts and post improvements here!

This script replaces recursively all nodes with links to a map file (link text ending on '.mm') with the content of the respective map. Check logfile for files that could not be found/inlined. Thanks to Dennis for asking for this feature.

Requires Freeplane after 1.2.8_02. With two minor adjustments also usable with older 1.2 versions (see script text).

<groovy name="inlineLinkedMaps"> // @ExecutionModes({ON_SINGLE_NODE}) def thisMap = node.map def newMap = cloneMap(thisMap.root) inlineIncludes(newMap.root)

def cloneMap(rootNode) { 

   def newMap = c.newMap()
   copyProperties(newMap.root, rootNode)
   rootNode.children.each{ newMap.root.appendBranch(it) }
   inlineIncludes(newMap.root)
   return newMap

}

// copies some of the various properties a node has from source to dest def copyProperties(dest, source) { 

   dest.text = source.text
   // only after 1.2.8_02
   dest.attributes = source.attributes.map
   dest.link.text = source.link.text
   if (source.note != null)
       dest.note = source.note
   dest.details = source.detailsText

}

// inserts linked maps into the node containing the link def inlineIncludes(rootNode) { 

   rootNode.find{ it.link.text && it.link.text.endsWith(".mm") }.each { include ->
       def url = getURL(include)
       if (url) {
           def childMap = c.newMap(url)
           copyProperties(include, childMap.root)
           include.link.text = null
           childMap.root.children.each{ child ->
               include.appendBranch(child)
           }
           // leads to an -ignorable- error upto 1.2.8_02
           childMap.close(true, false)
       }
   }

}

// handles relative paths and more def getURL(node) { 

   try {
       def uri = node.link.uri
       if (uri.scheme == null || uri.scheme == 'file') {
           def file = new File(uri.path)
           if (!file.isAbsolute())
               file = new File(node.map.file.parent, uri.toString())
           if (!file.exists()) {
               logger.warn("invalid link " + file + " - cannot inline")
               return null
           }
           return file.toURL()
       }
       else {
           return uri.toURL()
       }
   } catch (Exception e) {
       logger.warn("invalid link " + node.link.text + " - cannot inline", e)
       return null
   }

} </groovy>

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. // // 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 } c.statusInfo = NumberFormat.getInstance().format(result) </groovy>

Find all connected nodes

This script will find all nodes below the current node that have connections and list them under a new node created to hold the results called "connected nodes". I found this extremely useful when I have multiple connections reaching across subtrees in a large map. <groovy name="listConnectedNodes"> import java.text.NumberFormat; import org.freeplane.plugin.script.proxy.NodeProxy;

// @ExecutionModes({ON_SELECTED_NODE}) def createNewNode (node, text) { 

   def child = node.createChild()
   child.text = text
   return child

}

def getTargetNodes (connectors) { 

   connectors.each {
       def targetNode = it.getTarget()
       def sourceNode = it.getSource()
       result = createNewNode(resultNode, sourceNode.text + " --> " + targetNode.text)
   }

}

def getChildrenRecursive(node) { 

   if (node.isLeaf()) {
       return [node];
   }
   else {
       // father and sons
       return [node] + node.children.collect{ getChildrenRecursive(it) }.flatten();
   }

}

//******************************************************

thisNode = node resultNode = createNewNode(thisNode,"Connected Nodes") nodeList = getChildrenRecursive(thisNode) nodeList.each { 

   if (it.getConnectorsOut().isEmpty()) {
        // do nothing
   }
   else {
       def targets =  it.getConnectorsOut()
       getTargetNodes(targets)
   }

}

Find changed nodes

This script was suggested by Tobias Brown. It creates a new child node of the root node with shallow copies of the first maxCount changed nodes, ordered by modification time, starting with the most recently changed node. Note that the values in the first lines are meant for adjustment to your own preferences. <groovy name="listChangedNodes"> // @ExecutionModes({ON_SINGLE_NODE}) // == Config BEGIN // find all nodes changed since 1970-01-01. Limit the search to the last 48 hours by: new Date() - 2 def changedSince = new Date(0L) // maximum number of displayed nodes def maxCount = 50 // maximum length of cited text def maxLength = 50 // add modification time to the node reference? def addTimestamp = true // add connector to the changed node? def addConnector = false // == Config END

def df = new java.text.SimpleDateFormat("yyyy-MM-dd hh:mm")

// find() returns a unmodifiable list so we have to copy it in order to copy it. // The minus sign reverts the order. def matches = new ArrayList(c.find{ it.lastModifiedAt.after(changedSince) }).sort{ -it.lastModifiedAt.time }

def historyNode = node.map.root.createChild() historyNode.text = matches.size() + " nodes were changed since " + changedSince c.statusInfo = historyNode.text

if (matches.size() > maxCount) 

   matches = matches[0..maxCount-1]

matches.each{ node -> 

   def child = historyNode.createChild()
   def text = (addTimestamp ? df.format(node.lastModifiedAt) + " " : "") + node.plainTextContent
   child.text = text.length() > maxLength ? text.substring(0, maxLength-1) : text
   if(addConnector)
       child.addConnectorTo(node)
   child.link.set('#' + node.nodeID)

} c.select(historyNode) </groovy> Author: User:boercher


Scripts that need external libraries

With external Java libraries you can explore completely new application fields with Freeplane and accomplish amazing things. Remember: Groovy is fully Java compatible, i.e. you can use nearly any available Java library.

General installation instructions for external Java libraries

Java libraries normally come in form of .jar files which you have to make known to the application that wants to use them. Here's the way to do that in Freeplane:

1. Create a folder lib in your Freeplane user directory

2. Copy the .jar file to that directory.

3. Start Freeplane and add lib to Preferences -> Plugins -> Scripting -> Script -> Script classpath

4. Save and restart Freeplane

To install further .jar files in the future you just have to copy the .jar files to that lib directory and restart Freeplane.
