How to write macro for Notepad++?

Macros in Notepad++ are just a bunch of encoded operations: you start recording, operate on the buffer, perhaps activating menus, stop recording then play the macro.
After investigation, I found out they are saved in the file shortcuts.xml in the Macros section. For example, I have there:

<Macro name="Trim Trailing and save" Ctrl="no" Alt="yes" Shift="yes" Key="83">
    <Action type="1" message="2170" wParam="0" lParam="0" sParam=" " />
    <Action type="1" message="2170" wParam="0" lParam="0" sParam=" " />
    <Action type="1" message="2170" wParam="0" lParam="0" sParam=" " />
    <Action type="0" message="2327" wParam="0" lParam="0" sParam="" />
    <Action type="0" message="2327" wParam="0" lParam="0" sParam="" />
    <Action type="2" message="0" wParam="42024" lParam="0" sParam="" />
    <Action type="2" message="0" wParam="41006" lParam="0" sParam="" />
</Macro>

I haven't looked at the source, but from the look, I would say we have messages sent to Scintilla (the editing component, perhaps type 0 and 1), and to Notepad++ itself (probably activating menu items).
I don't think it will record actions in dialogs (like search/replace).

Looking at Scintilla.iface file, we can see that 2170 is the code of ReplaceSel (ie. insert string is nothing is selected), 2327 is Tab command, and Resource Hacker (just have it handy...) shows that 42024 is "Trim Trailing Space" menu item and 41006 is "Save".
I guess action type 0 is for Scintilla commands with numerical params, type 1 is for commands with string parameter, 2 is for Notepad++ commands.

Problem: Scintilla doesn't have a "Replace all" command: it is the task of the client to do the iteration, with or without confirmation, etc.
Another problem: it seems type 1 action is limited to 1 char (I edited manually, when exiting N++ it was truncated).
I tried some tricks, but I fear such task is beyond the macro capabilities.

Maybe that's where SciTE with its Lua scripting ability (or Programmer's Notepad which seems to be scriptable with Python) has an edge... :-)

[EDIT] Looks like I got the above macro from this thread or a similar place... :-) I guess the first lines are unnecessary (side effect or recording) but they were good examples of macro code anyway.


I recorded a macro and I found it in %APPDATA%\Notepad++\shortcuts.xml. It looks like posted in the first post of this thread.

I use NPP Ver. 5.9.6.2 with Win7.


Posting more than 10 years after the OP, but I think that this is still a relevant question (it is for me, at least). Today, there is quite some information in the Notepad++ User Manual, relating to the OP's question:

  • General Info about macros: https://npp-user-manual.org/docs/macros/
  • General explanation about the language used is in the config files docs: https://npp-user-manual.org/docs/config-files/#macros
  • Search and Replace Actions (as requested by the OP) are covered in more detail here: https://npp-user-manual.org/docs/searching/#searching-actions-when-recorded-as-macros

Here is a block of macro code: replace SEARCHTEXT by REPLACETEXT, using regular expressions, "." finds /r and /n, in every file matching the filter GLOBFILEFILTER in a folder PATH (no subfolders, not sure where this flag is defined/set).

<Macro name="REPLACE_IN_FILES_REGEX_DOT_FINDS_CR_AND_LF" 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="SEARCHTEXT" />
    <Action type="3" message="1625" wParam="0" lParam="2" sParam="" />
    <Action type="3" message="1602" wParam="0" lParam="0" sParam="REPLACETEXT" />
    <Action type="3" message="1653" wParam="0" lParam="0" sParam="PATH" />
    <Action type="3" message="1652" wParam="0" lParam="0" sParam="GLOBFILEFILTER" />
    <Action type="3" message="1702" wParam="0" lParam="1024" sParam="" /> 
        <!-- #COMMENT: "1024" seems to be the flag ". finds /n and /r". This is not in the documentation. -->
    <Action type="3" message="1701" wParam="0" lParam="1660" sParam="" />
</Macro>

Remarks about this code:

  • The path to the folder needs to end with a backslash.
  • Characters like <, >, & need to be escaped in the xml. Rather create your search and replace strings by recording a macro.

I found 'Python Script' plugin for Notepad++ more useful since with the plugin, I could write simple macros in the form of python and It has also got very good documentation and sample macros written in python as well. If you are quite comfortable with python, then I think 'Python Script' will provide justice. For more information, refer : http://npppythonscript.sourceforge.net/
