配置 jEdit

2015年8月18日

jEdit

jEdit 是一个以 Java 编写的编辑器。以 BeanShell 作为扩展脚本语言。

下载及安装

下载，当前的最新稳定版为 5.2.0。下载 Java-based installer, 因这个安装包是一个 Java 打包程序，可以在 Windows、Linux 及 OS X 上直接使用。

java -jar jedit5.2.0install.jar

选择安装目录为 D:\workspace\coder\java\jEdit\jEdit-5.2.0。

配置

目录结构

在目录 D:\workspace\coder\java\jEdit 下新建目录 jEdit\bin、jEdit\home、jEdit\etc。

Windows 启动脚本

jEdit.cmd 的内容为，

@SETLOCAL
@SET JEDIT_VER=5.2.0
@SET JEDIT_HOME=%JEDIT_HOME%
@SET JAVA_HOME=%JAVA_HOME%
@START %JAVA_HOME%\bin\javaw -Duser.home=%JEDIT_HOME%\home -Dsun.java2d.noddraw=true -Xms32M -Xms1024M -jar %JEDIT_HOME%\..\jEdit-%JEDIT_VER%\jedit.jar -settings=%JEDIT_HOME%\etc -background -reuseview %*
@ENDLOCAL

jEdit.vbs 的内容为，

args = ""
length = Wscript.Arguments.Count
If length > 0 Then
	For i = 0 To  length - 1
		args = args + " " + """" + Wscript.Arguments(i) + """"
	Next
End If
createObject("wscript.shell").run "jEdit.cmd" + args, 0

为了集成到右键菜单，(1) 修改注册表，新建项 HKEY_CLASSES_ROOT\*\shell\jEdit\command。 (2) 在这个项下，新建可扩充字符串值，其值为 wscript %JEDIT_HOME%\bin\jEdit.vbs "%1"，取名为 new。 (3) 导出项 HKEY_CLASSES_ROOT\*\shell\jEdit\command，保存为 setting_right_menu.reg。 (4) 用记事本打开 setting_right_menu.reg，将内容 "new"= 修改为 @=，保存。(5) 导入刚才修改后的注册表文件 setting_right_menu.reg。 (6) 重新刷新注册表项 HKEY_CLASSES_ROOT\*\shell\jEdit\command，可以发现，项下有两个串值，名称为 (缺省) 的字符串值，类型已经变化为 REG_EXPAND_SZ，内容跟刚才新建的、名称为 new 的串值相同。(7) 名称为 new 的串值已经不再需要，删除它。

执行命令，设置用户变量 JEDIT_HOME 的值，

SETX JEDIT_HOME D:\workspace\coder\java\jEdit\jEdit

修改用户的 Path 变量，附加 %JEDIT_HOME%\bin;。

OS X 启动脚本

#!/bin/sh
#
# Runs jEdit - Programmer's Text Editor.
#

# Find a java installation.
if [ -z "${JAVA_HOME}" ]; then
    echo 'Warning: $JAVA_HOME environment variable not set! Consider setting it.'
    echo '         Attempting to locate java...'
    j=`which java 2>/dev/null`
    if [ -z "$j" ]; then
        echo "Failed to locate the java virtual machine! Bailing..."
        exit 1
    else
        echo "Found a virtual machine at: $j..."
        JAVA="$j"
    fi
else
    JAVA="${JAVA_HOME}/bin/java"
fi

# Launch application.
exec "${JAVA}" -Duser.home=$JEDIT_HOME/home -jar "${JEDIT_HOME}/../jEdit-${JEDIT_VER}/jedit.jar" -settings=$JEDIT_HOME/etc -background-reuseview "$@"

启动 jEdit，

export set JEDIT_HOME=~/workspace/coder/java/jEdit/jEdit; export set JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home/jre; export set JEDIT_VER=5.2.0; . $JEDIT_HOME/bin/jedit.sh

.gitignore 的内容如下，

etc/jars-cache
etc/macros # 宏不放在该目录，而是放在其他地方，链接到该目录下
etc/PluginManager.download
etc/plugins
etc/settings-backup
etc/activity.log
