JEdit 宏 - 打开和保存文件

发布于 2024-07-09 04:41:59 字数 842 浏览 7 评论 0原文

我有一个 JEdit (BeanShell) 宏，它打开一个特定文件，然后立即将该文件保存到我的 c:\temp 文件夹中（这样我就不会意外更新真实文件）。

这是 bean shell 代码：

logFilePath = "c:\\temp\\aj.txt";
jEdit.openFile( view , logFilePath );
_buffer = jEdit.getBuffer(logFilePath);
_buffer.save(view,"c:\\temp\\backup.txt",true);

这给了我以下错误：

I/O Error
Each buffer can only execute one input/output operation at a time.  
Please wait until the current operation finishes 
(or abort it in the I/O progress monitor) before starting another one.

我尝试添加一个 while 循环来等待 buffer.isLoaded() 为 true，但这只是进入无限循环。
似乎有效的是弹出一个消息框（Macros.message）。不过，我真的不想进行这种不必要的对话。

我不太懂java，所以请告诉我我是否犯了菜鸟错误。

更新：

添加了我自己的答案，以显示 Serhii 的答案指向的代码。

I have a JEdit (BeanShell) macro which opens a specific file then immediately saves the file to my c:\temp folder (so that I don't accidentally update the real file).

Here is the bean shell code:

logFilePath = "c:\\temp\\aj.txt";
jEdit.openFile( view , logFilePath );
_buffer = jEdit.getBuffer(logFilePath);
_buffer.save(view,"c:\\temp\\backup.txt",true);

This gives me the following error:

I/O Error
Each buffer can only execute one input/output operation at a time.  
Please wait until the current operation finishes 
(or abort it in the I/O progress monitor) before starting another one.

I have tried adding a while loop to wait until buffer.isLoaded() is true, but that just goes into an infinite loop.
What does seem to work is popping up a message box (Macros.message). However, I really don't want to have this unnecessary dialogue.

I don't know much java, so please tell me if I'm making a rookie mistake.

Update:

Added my own answer to show the code pointed to from Serhii's answer.

您可以尝试此解决方案，调用VFSManager.waitForRequests() ;。

这是有效的

这是上面 Serhii 的答案指向的代码。

添加VFSManager.waitForRequests(); 在 jEdit.openFile() 命令之后。

完整代码

logFilePath = "c:\\temp\\aj.txt";
jEdit.openFile( view , logFilePath );

VFSManager.waitForRequests();

/* 
    VFSManager.waitForRequests();

    jEdit waits then for the file to be completely loaded before continuing 
    ... It's designed for waiting on all 'pending I/O requests'".
*/

_buffer = jEdit.getBuffer(logFilePath);
_buffer.save(view,"c:\\temp\\backup.txt",true);

This Works

This is the code pointed to by Serhii's answer, above.

Add VFSManager.waitForRequests(); after the jEdit.openFile() command.

Full Code

logFilePath = "c:\\temp\\aj.txt";
jEdit.openFile( view , logFilePath );

VFSManager.waitForRequests();

/* 
    VFSManager.waitForRequests();

    jEdit waits then for the file to be completely loaded before continuing 
    ... It's designed for waiting on all 'pending I/O requests'".
*/

_buffer = jEdit.getBuffer(logFilePath);
_buffer.save(view,"c:\\temp\\backup.txt",true);

你也可以不那么大胆。

使用 jEdit.openFile() 的返回值，这已经是 Buffer，不需要 getBuffer()
不要调用 VFSManager.waitForRequests() 等待所有请求完成，而只需将 BufferListener 添加到您获得的 Buffer来自 jEdit.openFile() 并在此侦听器的 bufferLoaded 方法中进行保存调用:-)
