Hello,

I'd like to add reformatting capabilities to UE. I already have a tool that can reformat whole files, but I'd like to reformat just a selection, for example. I have a program that can take the code from the clipboard, reformats it and puts it back into the clipboard) and I'd like to use it.

The UE macro should do this:

- (optional) save the current clipboard content
- save the current selected text to the clipboard (this is the text that needs to be reformatted)
- launch an external application (something like reformat.exe -useClipboard)
- replace the selected text with the one from the clipboard (reformat.exe has modified the text in the clipboard and now it's nice and formatted )
- (optional) restore the previous clipboard content

Is this be possible with macros?
Thanks

Well it seems I haven't explained very well what I want:
I need to format java code to look nicer. Something like putting the { on a separate line, removing extra blank lines, vertical-aligning if/else, etc. Also my java code includes many #define, #include and other preprocessor directives that I want to align nicely.
The external program is made by me so I have full control of what it does. It takes the text from the clipboard, formats it and then puts it back into the clipboard.

And now, my question
I want to write a macro that takes the selected text, puts it into the clipboard, calls the external program, waits for it to finish and then replaces the selection with the text from the clipboard. Optionally it should keep the previous clipboard content. Unfortunately I don't have much experience in writing UE macros. So I need some hints, like: is there a limit to the length of text that can me put to/from clipboard? Or is it possible to wait for the external program to finish, or UE launches it and then continues without waiting?

Thank you
