TidyErrorLabel=Tidy Error TidywarningLabel=Tidy Warning Next, the annotation none none declarations must be registered with the NetBeans Platform. This is performed in the XML layer. The following lines need to be added to the already existing Editors folder (<folder name="Editors">.


Handling the Output <folder name="Anno none for none tationTypes"> <file name="org-yourorghere-nbtidyintegration-TidyWarning Annotation.xml" url="TidyWarningAnnotation.xml"/> <file name="org-yourorghere-nbtidyintegration-TidyError Annotation.

xml" url="TidyErrorAnnotation.xml"/> </folder>. The names match the c urrent directory structure, with slashes replaced by dashes. The annotations are now ready for use. To integrate them into the example, the readOutput() method from the TidyRunnable class must be modi ed.

If the output line matches the pattern from the regular expression, an annotation is created. The pattern then extracts all required information for displaying the annotation..

static void readOutpu none for none t (OutputWriter writer, DataObject dataObject, InputStream errStream) { LineCookie lc = (LineCookie) dataObject.getCookie (LineCookie.class); TidyOutputListener listener = new TidyOutputListener(dataObject); try { BufferedReader error = new BufferedReader (new InputStreamReader (errStream)); String err = null; while ((err = error.

readLine ()) != null) { Matcher matcher = TidyOutputListener.PATTERN.matcher (err); if (matcher.

matches ()) { TidyAnnotation.createAnnotation(lc, matcher); writer.println (err,listener); } else { writer.

println (err); } } } catch (Exception e) { writer.println ("Could not read Process output " +e); } }. 23 . Use Case 1: Jens Trapp on NetBeans Module Development Adding annotations is only half of the problem; we also need to remove them if the error or warning has been corrected in the Source Editor. For the purposes of this example, we can manage this quite easily by removing annotations as soon as the lines they reference are changed. We do not check if the changes actually make the lines valid.

Furthermore, the clear() method in the initializer of the TidyRunnable class is called each time the action is performed, thereby removing all previously created annotations (Figure 23.4)..

/** Initialize HTML T none for none idy runnable.*/ public TidyRunnable(Node[] nodes, String commandLineArgs) { TidyAnnotation.clear(); this.

nodes=nodes; this.commandLineArgs=commandLineArgs; }. Figure 23.4: HTML Tidy annotations Annotations are an ea none none sy way to mark areas in the Source Editor. For further information on annotations, consult the chapter on error annotations ( 17)..

Con guring the Tool Con guring the Tool In its current state, our HTML Tidy module runs ne in the IDE. However, it might not run on every machine because the path to the executable has been hardcoded. This is commonly considered bad practice and ought to be changed before the module can be published.

The user should be able to con gure the path of the executable. As described in Section 18.1, the NetBeans Platform provides central con guration functionality, as well as an easy way to plug module-speci c con gurations directly into the platform.

Con guration functionality is accessible through Tools . Options from the IDE none for none s main menu. The Options window opens in standard mode where frequently accessed parameters can be set (see Figure 23.5).

Options are grouped into categories, each category being displayed in its own panel. There is also a Miscellaneous category grouping all options that cannot be classi ed into the given categories. We will use the Options Panel wizard which allows us to integrate the module s con guration settings into the Options window.

. Figure 23.5: HTML Tidy con guration Extending the Options Window It is possible to gen erate a new category for the Options window, with a corresponding icon in the left sidebar. Otherwise, new con guration settings can.
