Mac – How to delete rest of the line after a specific string

Yes you can, I just tried to record a new macro, did a search and replace and it successfully saved the action so when I played the macro, it did the same search and replace action.

I am not an expert at Notepad++ Macros, but I am guessing you are... I opened a random file and created a macro called test. It looked for a word called "snip" and replaced it with "blaa".

Opening up the shortcuts.xml file after closing Notepad++ reveals this new macro:

<Macro name="test" Ctrl="no" Alt="no" Shift="no" Key="0">
    <Action type="3" message="1700" wParam="0" lParam="0" sParam="" />
    <Action type="3" message="1601" wParam="0" lParam="0" sParam="snip" />
    <Action type="3" message="1625" wParam="0" lParam="0" sParam="" />
    <Action type="3" message="1602" wParam="0" lParam="0" sParam="blaa" />
    <Action type="3" message="1702" wParam="0" lParam="768" sParam="" />
    <Action type="3" message="1701" wParam="0" lParam="1608" sParam="" />
</Macro>

This is tested and works on my machine, I can manually modify this file and the changes get reflected and work in Notepad++.

Please note however, the shortcuts.xml file (located in your Appdata folder), only gets loaded and saved on opening/exiting Notepad++.

To get the prefixes (the text before the dashes), press Ctrl+H and fill out the fields as follows:

To get the suffixes (the text after the dashes), press Ctrl+H and fill out the fields as follows:

This breaks if there are any dashes in either the prefix or the suffix.

If you need to get both separately, just capture the results from the first replace to a different file (or the clipboard), then press Ctrl+z and perform the second replace.

If you need to include the dash and/or spaces, you can add them as needed in the "Replace with :" text box before or after the replacement placeholder.
