Getting the file name without extension in a Windows Batch Script
提问by Dan Herbert
I'm trying to create a right-click context menu command for compressing JavaScript files with YUI compressor. My ultimate goal is to try to get this to run on a context menu:
我正在尝试创建一个右键单击上下文菜单命令，用于使用 YUI 压缩器压缩 JavaScript 文件。我的最终目标是尝试让它在上下文菜单上运行：
java.exe -jar yuicompressor-2.4.2.jar -o <filename>.min.js <filename>.js
I know I can use the variable %1to reference the file name being opened. I can't figure out how to get this command into a batch file syntax and haven't been able to find any answers online.
我知道我可以使用该变量%1来引用正在打开的文件名。我无法弄清楚如何将此命令转换为批处理文件语法，并且无法在线找到任何答案。
Update:
Jeremy's answer (+comments) worked. For anyone who stumbles upon this, here is what I had to do:
更新：
杰里米的回答（+评论）有效。对于任何偶然发现这一点的人，这是我必须做的：
In the action I created for the JavaScript file, I used this as the command:
在我为 JavaScript 文件创建的操作中，我将其用作命令：
minify.bat "%1"
Which calls my batch script, which looks like this:
它调用我的批处理脚本，如下所示：
java.exe -jar yuicompressor-2.4.2.jar -o "%~dpn1.min.js" %1
For the batch script, keep in mind that the code above assumes the directories for java.exe & yuicompressor are both added to your PATHvariables. If you don't add these to your path, you'll have to use the full path for the files.
对于批处理脚本，请记住上面的代码假定 java.exe 和 yuicompressor 的目录都添加到您的PATH变量中。如果不将这些添加到路径中，则必须使用文件的完整路径。
The sequence %~dpnis used to get:
该序列%~dpn用于获得：
%~d- The drive%~p- The path%~n- The file name
%~d- 驱动器%~p- 路径%~n- 文件名

Change the action to call a batch file:
更改调用批处理文件的操作：
RunCompressor.bat "%1"
Use %~n1to get the filename without the extension in RunCompressor.bat:
使用%~n1来获取文件名没有在RunCompressor.bat扩展：
start javaw.exe -jar yuicompressor-2.4.2.jar -o "%~n1.min.js" "%1"
start javaw.exe closes the command window when running the batch file.
start javaw.exe 在运行批处理文件时关闭命令窗口。

回答by Jeremy Stein
Write your own class that determines the output filename to send to YUI compressor.
编写您自己的类来确定要发送到 YUI 压缩器的输出文件名。
java.exe -cp yuicompressor-2.4.2.jar MyClass "%1"
