SciTE Java API

(转自http://www.burgaud.com/scite-java-api/)

SciTE (Scintilla Text Editor) supports API and Keyword files to customize some aspects of the editor for a given programming language. Keywords files extend the highlighting of source code files (i.e. Class names in Java), and API files allow to displays calltips, basic form of the popular Microsoft Intellisense ®. The BeanShell script, SciteJavaApi.bsh, generates both the Java API and the Keyword files for your current Java Runtime Environment.

Summary

• Product: SciTE Java API
• Version: 1.5
• Date: 12/23/2006
• Operating System: Win32/Linux
• License: Open Source Software, MIT License
• Download Script: SciteJavaApi15.zip (8kB)
• Download Script and BeanShell 2.0b5: SciteJavaApi15_bsh.zip (364kB)
• Download Java API Files: SciteJavaApi_api_files.zip (947kB)

Requirements

If you just need the API and Keyword files, download SciteJavaApi_api_files.zip (947kB) and jump to section SciTE Configuration.

In order to run SciteJavaApi.bsh you need:

1. A recent version of the Java Runtime Environment.
2. A recent version of the Java Dynamic Language BeanShell. Some packages available for download already include the BeanShell library.

Of course, you also need SciTE (Scintilla Text Editor) in order to use the Java API files.

Installation and Usage

• Download the latest release: SciteJavaApi15.zip (8kB). If you don’t have already BeanShell, download the package including it: SciteJavaApi15_bsh.zip (364kB).
• Extract the content of the SciteJavaApi zip file to your hard drive.
• Assuming SciteJavaApi.bsh and bsh-2.0b5.jar being in C:\SciteJavaApi, execute:

C:\SciteJavaApi>java -cp bsh-2.0b5.jar bsh.Interpreter SciteJavaApi.bsh

• You should get the following output:

Beanshell SciTETools Menu
- Type "q|Q" and [ENTER] to quit.
- Type "1" and [ENTER] to build a Java Keywords file for SciTE.
- Type "2" and [ENTER] to build a Java Api file for SciTE.
Your choice:

• Choose 1 or 2 to generate respectively the Java Keywords file or the Java API file.
• To generate the API files for a different Java version, invoke the corresponding Java command. You can achieve this by using the environment variable JAVA_HOME. See the shell script java_api.sh and windows batch file java_api.bat included in the package for more detailed examples.
• After generating the API files, you can configure SciTE.

SciTE Configuration

• Copy the Java API and keywords files in the install directory of SciTE (where the default SciTE properties files are).
• Assuming that the API and Keywords files are respectively: java150.api and java150_kwd.properties.
• Open the file cpp.properties available in the install directory of SciTE.
• Add the following lines (check first if similar lines are already existing and modify accordingly):

import java150_kwd
api.*.java=$(SciteDefaultHome)\java150.api
calltip.java.word.characters=._$(word.chars.cxx)
calltip.java.parameters.start=(
calltip.java.parameters.start=)
calltip.java.parameters.separators=.

Note: In versions prior to 1.5, SciteJavaApi.bsh generated the keyword file with the format java150.kwd. You had to rename the file to java150_kwd.properties, in order to allow the import to work.

Configuring SciTE as explained above will enable the following features:

1. Java classes highlighting,
2. Calltips,
3. Auto completion.

Java Classes Highlighting

The Java classes highlighting is automatically enabled due to the import of the keywords file. Classes are highlighted as shown in the following screen capture:

To modify the highlight color, modify the value of the style associated with keyword2 in the file cpp.properties:

...
# Keywords2
style.cpp.16=fore:#B00040
...

Note: To limit the size of the keywords properties file, only classes from packages started with java are included. This excludes classes from javax packages for example.

Calltips

With the calltip configuration, such as the one described in the section Scite Configuration, when you type the open parenthesis after a method name, a scrollable pop-up help box displays the possible parameters of this method. You can enter the parameters accordingly, and also use the mouse to navigate up and down to see the other method signatures. You can also invoke calltips by pressing Ctrl+Shift+Space with the cursor located inside of the method parameter parenthesis.

Auto Completion

SciTE allows you to customize the behavior of the word completion feature, based on the source code being edited. In the case of Java, I simply suggest to take advantage of the the word completion from the API file by invoking it via the shortcut key Ctrl+Space or Ctrl+i, as shown in the screen capture below:

Though not directly related to the auto completion provided by the API file, there is another auto completion feature available in SciTE. By typing Ctrl+Enter just after at least one character, SciTE will open a list of words already available in your file and matching the first characters of the word being typed.

Compatibility

• Version 1.5 of the BeanShell script was tested with BeanShell 2.0b4 and 2.0b5, Java 1.3.1, 1.4.2, 1.5.0 and 1.6.0, on Windows XP and Linux. BeanShell 2.0b5 is not compatible with Java 1.3.1 and Java 1.4.2: it causes the error java.lang.UnsupportedClassVersionError.
• Version 1.4 of the BeanShell script was tested with BeanShell 1.3, 2.0b2 and 2.0b4, Java 1.4.2 and 5.0.
• Version 1.3 of the BeanShell script was tested with BeanShell 2.0b1. It is not compatible with previous versions of BeanShell.
• Version 1.2 of the script is not compatible with BeanShell 1.3 nor 2.0b1. It is only working with BeanShell 1.2.
