Not sure, but I think there was no hint that this JAR needs Java 6 to run.
This prohibits its use in our project, though :-( too bad.
Maybe you could refactor it.

It would also be nice to add folding functionality to java editor or xml
editor.

When running RESTClient with JSyntaxPane 0.9.3 in Java 5, I am getting this
trace:

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError:
java.util.Properties.stringPropertyNames()Ljava/util/Set;
    at jsyntaxpane.DefaultSyntaxKit.initKit(DefaultSyntaxKit.java:185)

r.java:16)

org.wiztools.restclient.ui.ScriptEditorFactory.getXMLScriptEditor(ScriptEditorFa
ctory.java:19)

I think java.util.Properties has introduced stringPropertyNames() method in
version 6. We have to find corresponding method in Java and update the
JSyntaxPane code so that it is compatible with Java 5.

What steps will reproduce the problem?
1. Edit SyntaxTester to change the JEditorPane's selected color (eg.
pane.setSelectedTextColor(Color.magenta))
2. Start SyntaxTester
3. Select some text

What is the expected output? What do you see instead?
Expected: selected text is orange
Actual: selected text is the same color as unselected text

The problem is that SyntaxView.drawSelectedText() calls
drawUnselectedText() instead of implementing the selected text method.  The
workaround seems to be commenting out SyntaxView.drawSelectedText()

See
http://code.google.com/p/jsyntaxpane/source/browse/trunk/src/main/java/jsyntaxpa
ne/SyntaxView.java#49

Current version does not support line wrapping.  It will be good to have
that feature.
Need to fine tune the Line Number if that is supported.  May need to create
a new document or view instance to support that.

I came across the above method which should make registering and even using
the library much easier.  The only downside in my opinion is that now if
you need to use your own lexer, you also need to create a SyntaxKit
implementation.  Mind you, it will be generally just one liner class with a
constructor that calls default SynatxKit with the proper lexer.

When that is done, you can actually use code like:
JEditor.setContentType("text/java")

I have an implementation that works fine, but needs some cleanup and a
clean way to register the various editor kits to the languages.

Any suggestions?

What steps will reproduce the problem?
1. Change the TokenType.DEFAULT color to Color.ORANGE in SyntaxStyles
2. Start SyntaxTester
3. Type @ (it will be orange)
3. Type ! (now the string "@!" will be black)

What is the expected output? What do you see instead?

Expect the string "@!" to use the default color (orange).

Please use labels and text to provide additional information.

SyntaxView:56
graphics.setColor(Color.BLACK);

should be 

SyntaxStyles.getInstance().setGraphicsStyle(graphics, TokenType.DEFAULT);

Unless I am mistaken, there is no way to change the keyword for a language.
This is a very useful feature because, for example, by changing the
keywords most of C++ based languages can be supported (the same lexer as
Java can be used)

your jsyntaxpane is very cool, but recently I focus on my own XML editor,
which can use your library. but a shortcoming is tag auto completion, e.g.

when I press <Test>, another </Test> should be automatically followed
because of it is an XML document.

Could you please fix it?

What steps will reproduce the problem?
1. Use jsyntaxpane on Macintosh
2. Undo/Redo keys are control-Z/control-Y instead of mac standard 
command-Z/command-Y

I would suggest the following diff to account for different platforms menu keys:

What steps will reproduce the problem?
1. launch SyntaxTester
2. type 1

What is the expected output? What do you see instead?
Expected: SyntaxTester.jEdtTestCaretUpdate() gets the number token from the
Document and displays it in lblToken.
Actual: SyntaxTester.jEdtTestCaretUpdate() gets a null token.

Please use labels and text to provide additional information.

The problem is that caretUpdate() is called during
SyntaxDocument.insertString()'s call to super.insertString(), which means
CaretListeners are called before SyntaxDocument.parse().  Since the
SyntaxDocument is only "half" updated, SyntaxDocument.getTokenAt() returns
a value that is out of date.

The current implementation cannot support tokens to be embedded within
tokens.  Something like a Groovy ${val} in a Groovy String cannot be
highlighted.  Only the Complete String can be highlighted.

This change requires a slightly major refactoring of the way {{{Tokens}}}
are returned to the {{{SyntaxDocument}}}, and possibly in the
{{{SyntaxView}}} to handle overlapping tokens.  The {{{Lexers}}} will also
need to change to use proper states instead of just Regexp for some constructs.

But the possibilities are very nice indeed.  Highlighting JavaDocs, and
Groovy Strings will look very nice.

Anybody interested in having this?  If so, please add a comment and if
demand is there, I'll push it up the list of things to do.

What steps will reproduce the problem?
1. Add another JEditorPane and JScrollPane to SyntaxTester

Before uploading to the Maven public repository, it would be good to have a
new version released. There has been some changes in the code since last
release.

The version numbering scheme also needs to change. Having the date as
versioning detail is convenient from the developer perspective, but from
the user perspective difficult to remember. Also some OpenSource software
which had this type of naming are ordered wrongly in the MVNRepository
search page. For example:

http://www.mvnrepository.com/artifact/commons-pool/commons-pool

Older version files are shown in the top, which might tempt unwary users to
include that instead of the latest stable version.

So what is the best version? Well, this has to be just thought out. My
personal preference would be something like 0.8.0. This indicates it is a
fairly stable product which has not yet reached 1.0 release.

Once you let me know the version number, I can create that version, tag it,
and open an issue to upload to the Maven public repository.

What steps will reproduce the problem?
1. instanciate a new JEditorPane
2. perform a setText on it with some content
3. call setContentType("text/java") on this JEditorPane

What is the expected output? What do you see instead?
It should work fine since the component is not visible yet.
Unfortunately, a NPE is thrown.

What version of the product are you using? On what operating system?
0.9.4a on OSX 10.6


Please provide any additional information below.

A NPE is thrown in the getLineNumber() method of ActionUtils class because
the JEditorComponent has not been sized yet. Therefore, the call
editor.modelToView(pos) will return a null reference, and the next
instruction r.y will throw a NPE.

very useful component, thanks.

how can i change the font family used?  i've tried using setFont() and
setting the component to honour the properties, but it just makes the
spacing bigger.

What steps will reproduce the problem?
1. checkout
2. mvn package (took me 6 minutes to download and compile after a fresh
maven install)
3. java -jar jsyntaxpane.jar

What is the expected output? What do you see instead?
Tester should start, but get:
Failed to load Main-Class manifest attribute from
jsyntaxpane-0.9.0.jar

You should probablly add the jar manifest and the set the main class for
this to work.

Please use labels and text to provide additional information.

What steps will reproduce the problem?
1. launch SyntaxTester
2. press ctrl-z

What is the expected output? What do you see instead?

Expected: no action, the original text is the initial state to the user
Actual: the editor becomes empty, which is the initial state to the code

I think SyntaxDocument/SyntaxKit should call
CompoundUndoManager.discardAllEdits() at the right time, or there needs to
be a public method in SyntaxDocument so the client can clear edits when
they choose.

This is an initial version of the flex file to support c syntax..
it's a slighly modified version of the one found in jhighligh.
i hope it's useful

What steps will reproduce the problem?
1. Create an editor pane for an xml document.
2. Paste the following into the document:
    <textfield first="" second="" />

What is the expected output? What do you see instead?
I expect no coloring, but the library appears to color from the second
double-quote to the third inclusive.


What version of the product are you using? On what operating system?
0.9

Please provide any additional information below.
N/A

-What steps will reproduce the problem?
Create an EditorPane and set the SyntaxKit as EditorKit. 
The coloring should be for XML.

editorPane = new JEditorPane();
editorPane.setEditorKit(new SyntaxKit("xml"));

- What is the expected output? What do you see instead?
As seen in the attached picture, whenever there is a backslash in an
attribute value the coloring bails out. See the path attribute for example.

  <subst drive="x:" path="O:cs40_fds_emafra" /> <!-- Colored correctly -->
  <subst drive="x:" path="O:\cs40_fds_substance" /> <!-- incorrect -->
  <subst drive="x:" path="O:\\cs40_0_sdp_ec_emafra" /> <!-- incorrect -->

What version of the product are you using? On what operating system?
I'm using the 080629a version on windows 2000 / JDK 1.6.0

regards

/frans

The screenshot displays the problem.

What steps will reproduce the problem?
1. create a syntaxpane in editor pane(xml, java...)
2. type xml text or java text in relative syntaxpane(I haven't tried other
syntaxpanes)
3. if character in syntaxpane is bold, the character size will be enlarged,
but the cursor won't change the position. I think the cursor should also be
next to the bold characters, not still stay in position where next to the
character when not bold.

OS: Windos XP sp2, en_US.
JDK:1.6.0_07

Are you planning to support the python language ?

Thanks

What steps will reproduce the problem?
1. Set type to java
2. paste: 
"public void foo{
}"
3.try to add lines after the last } 

What is the expected output? What do you see instead?
You should be able to add lines

Provide an unsigned jar as part of the distribution so that applications
can sign the jar as required and not rely on the expiration date set in the
prebuilt jar (currently around September 2008).

A very nice to have would be highlighting matching parentheses (, [ or {

What steps will reproduce the problem?
1. I instantiated a jsyntaxpane with a "sql" editorkit
2. Type 2 or more rows of text
3. Try to move caret up or down with up or down arrows

I expect the caret to move up or down but the caret does not move. Left and 
right arrows work 
OK.

Hello 
I am trying to integrate your project with my program given here below

         JEditorPane editorPane = new JEditorPane("text", "yahoo");
         editorPane.setEditable(true);
         editorPane.setEditorKit(new SqlSyntaxKit());
         editorPane.setContentType("text/sql");

         JFrame frame = new JFrame();
         frame.getContentPane().add(editorPane, BorderLayout.CENTER);
         frame.setSize(1000, 1000);

Can you please help me understand about where am I going incorrect.

Thank you

If java.flex and JavaLexer are GPL, then the entire project must be GPL. 
Hopefully this is a typo and java.flex is Apache 2.0.

Can we get some build instructions on the website?  Before it used maven, I
was able to check out the source into Eclipse and use it right away.

Now it won't build because the package names are wrong, the lexer classes
are missing, etc.  I installed maven and it generates the lexers, but the
packages are still incorrect, and if I refactor in eclipse I get conflicts
when I update.

I'd like step by step instructions of how to compile and edit the source.

I think you must add code completion for SQL Script.
I wish your library will have SQL Completion like on Netbeans 6.5

it would be nice to get an code completion just like Java IDE Eclipse. When
Ctrl + space is pressed, a popup menu appears to help user select words.

For instance, I can pass two arrays:

String[] text =  {“Name”, “Comment”};
Icon[] icons = {…..};

Text array is for the text of Intellisence and icons array is for the icons
on the left side.

Possible request: 

1. the Intellisense popup menu appears wherever Ctrl + Space is pressed 
2. if there is no letter before the cursor, IntelliHint will show all the
items from text array 
3. if there is a letter before the cursor, IntelliHint will only show the
items beginning with the letter from text array 
4. if the item from popup menu is selected, the corresponding text should
be inserted 

I am the project owner of: http://code.google.com/p/rest-client/

Your project seems to match our requirement. One glitch though, the project
is not available in Maven repository. Can you upload to Maven repository?

http://maven.apache.org/guides/mini/guide-central-repository-upload.html

I also see that your build is happening through Netbeans supplied build
scripts. If you need, I can help you convert your project to Maven.

What steps will reproduce the problem?
1. Start SyntaxTester
2. Insert text (must have vertical scrolls)
3. Change content from drop-down list

The method 'stringPropertyNames()' does not exist in Java SE 5.0.

1) It displays line numbers for lines that don't exist (in fact for the

e.g. you type in as follows:

} else {

The result looks like this afterwards:

if (k == 1) {
    } else if (k == 2) {
        else {
        }

It would be better to separate indentation and
de-indentation actions; the first could be triggered
by pressing Return, the other by entering a closing
brace (}).

Besides, comments aren't recognised at indent time, like:

if (true) { // do it always

Here some used util methods:

class StringTools

  public static String fillString(String source, int repeat) {
    StringBuffer buffer = new StringBuffer();
    for (int i = 0; i < repeat; i++) {
      buffer.append(source);

    if (null == result) {
      result = ""; //$NON-NLS-1$
    }

    return result;
  }
  public static boolean isEmpty(String s) {
    return (null == s) || (0 == s.length());
  }

class JavaScriptKit

  public static int getTabSize(JTextComponent aComponent) {
    Integer tabs = (Integer)
aComponent.getDocument().getProperty(PlainDocument.tabSizeAttribute);
    return null == tabs || tabs.intValue() == 0? 4 : tabs.intValue();
  }

What steps will reproduce the problem?
1. Add an EditorPane.
2. Set the type to text/java.
3. Observe with -Dswing.aatext=true

What is the expected output?
* Anti-aliased text.

What do you see instead?
* Jaggy font rendering.

What version of the product are you using? On what operating system?
* Ubuntu 8.04


Please provide any additional information below.
* The font *is* aliased if I don't set the content type.

What steps will reproduce the problem?
1. instantiated a new JEditorPane
DefaultSyntaxKit.initKit();
setContentType("text/java");

2. add the lines

import com.xyz.model.billing.ChargeModel;
charge : ChargeModel()

3. click into the word ChargeModel

4. Both words are highlighted in light brown

3. placed the cursor before the C. 
   held down shift
   moved cursor after the l

4.  The chargemodel is now selected such that I can copy but it still
displays the original highlighting - I cant tell I actually selected it

5.  I click away elsewhere in the editor

6.  The two ChargeModels are still highlighted with the light brown selection

What is the expected output? 

If a word is selected which appears else where the selection display should
not interfere with the standard editor highlighting functionality.

What version of the product are you using? On what operating system?

jsyntaxpane-0.9.3a.jar
Windows XP

Please provide any additional information below.

If I can disable this particular feature that would be great

What steps will reproduce the problem?
1. Use Tester 
2. Set to XML
3. notice some text is not displayed.
4. Clear text, and type first <
5. The first < is not shown until full tag is displayed

What steps will reproduce the problem?
1. Type in a parameterless method name e.g. thisclass.open();
2.
3.

What is the expected output? What do you see instead?

As I type I expect to see (); however I end up with ();) due to the 
additional parenthesis.

What version of the product are you using? On what operating system?

JSyntaxPane-080623a.jar  windows

Please provide any additional information below.

This was addressed in Eclipse at one point.  If the user opens a 
parentheses and you add one, any parenthese typed next to the one you 
added should replace, not add an additional one.  Of course the logic is 
probably tougher than that. 

EndOfLineStringProperty is supposed to automatically find out the new line 
separator, but that ain't working.  I also tried setting it manually to no 
avail.  Since EndOfLineStringProperty is a property of the 
DefaultEditorKit, I have to assume that JSyntaxPane is the culprit.  Then 
again, who knows, there might be something else I'm not seeing.

What steps will reproduce the problem?

1. Add a document filter to the SyntaxDocument.  For example in
SyntaxTester.jCmbLangsItemStateChanged after you set the EditorKit:

((SyntaxDocument) jEdtTest.getDocument()).setDocumentFilter(new
DocumentFilter());

2. Launch the SyntaxTester and start editing.  The syntax highlighting
won't update as you type.

What is the expected output? What do you see instead?

Expect SyntaxDocument.parse() to get called, but SyntaxDocument doesn't
override AbstractDocument.replace() (which is called by the
DocumentFilter's FilterBypass).  So it goes around the SyntaxDocument, and
the highlight doesn't update.
