Macro script when txt content changes
-
I never thought this day would come, but now that it has, I’ll take the opportunity to tell, er - only half the truth. :-D
The section is not 100 correct in the Scintilla documentation, there is one small way and that is to intercept the SC_MOD_INSERTCHECK,
then, and only here, the text may be changed.@Mirko-Rossi
What puzzles me a bit is the document monitor, when it is on, the document is read-only from the Npp point of view, isn’t it?
If you are willing to explain in more detail what needs to be done, and if you are willing to use the PythonScript plugin, then I suppose we can find a solution for you. -

- the SCI_GETMODIFY only returns true if scintilla thinks the contents have changed; since the View > Monitoring (tail -f) mode (and presumably the document monitor plugin) reload the contents in a way that scintilla knows about it, scintilla claims the contents haven’t changed… because they haven’t been edited since the last time scintilla has loaded it from disk
- I thought of trying to hook into notepad++'s FILEBEFORELOAD, but that only gets triggered when opening a new file, not from File > Reload From Disk or View > Monitoring (and thus, presumably not from the plugin)
- Per @Scott -Sumner’s quick-and-dirty “which notification is it using” script,. the only notification that gets triggered repeatedly in View > Monitoring (tail -f) is the NPPM_BUFFERACTIVATED, which isn’t one I thought would be triggered at all.
- If your idea doesn’t pan out, I would go down the BUFFERACTIVATED route, and store a crc32 of the contents in a Python
dict
(with the filepath as the key and the crc as the value); when the notification is triggered, it would recompute the crc and compare-to-stored: if crc32 changed, then run the other tasks and update thedict
). But yours will probably be better
- If your idea doesn’t pan out, I would go down the BUFFERACTIVATED route, and store a crc32 of the contents in a Python

thank you all for the quick responses and I apologize for my very rough english.
The key combination “Ctrl + Shift + 9” simply calls a macro.
The txt file is generated by an old radio automation and contains a simple text “Title - Interpreter”. Below is an example of the txt:
“Regardless - Raye”I need to invert the title with the interpreter in order to allow the correct association of the cover albums that are requested and retrieved by the streaming players.
I have created the macro and it works correctly; The whole process, up to the final acquisition of the cover, works … obviously by manually activating the macro.I used notepad ++, the macro and only the “Document monitor” plugin (which reads the file in real time).
the txt is updated every song change and so I wanted to create a script, which calls the macro or the key combination, whenever the content of the file changes.
thank you all
Mirkograzie a tutti per le rapide risposte e mi scuso per il mio inglese molto approssimativo.
La combinazione di tasti “Ctrl+Shift+9” richiama semplicemente una macro.
Il file txt viene generato da una vecchia radio automation e contiene un semplice testo “Titolo - Interprete”. A seguire un esempio del txt:
“Regardless - Raye”Ho necessità di invertire il titolo con l’interprete, al fine di permettere l’associazione corretta delle cover album che vengono richieste e recuperate dai player streaming.
Ho creato la macro e funziona correttamente; Tutto il processo, fino all’acquisizione finale della cover, funziona…ovviamente attivando manualmente la macro.ho usato notepad++, la macro e il solo plugin “Document monitor” (che legge in real time il file).
il txt viene aggiornato ogni cambio canzone e quindi volevo creare uno script, che richiama la macro o la combinazione di tasti, ogni qual volta il contenuto del file cambia.
grazie

PythonScript
no problem, just get to the solution
-
So if I’m putting the pieces of the above together correctly…
The idea of using SC_MOD_INSERTCHECK, if it will truly work in this case, would probably require the PythonScript callback, and not the macro, to do the changing of the text? At least that’s the only way I’ve ever used such a thing (via the
editor.changeInsertion()
function).So…probably publishing the macro here, and having its functionality converted to PythonScript code, is probably a good idea?
-
I think so. if the final result doesn’t change, you can use PythonScript completely.
is there any way to give you the code of a macro? to then convert it with PythonScriptthank you
penso di si. se il risultato finale non cambia, si può usare completamente PythonScript.
esiste un modo per darvi il codice di una macro? per poi convertirlo con PythonScriptgrazie

</Macro>it’s enough?

the path to the file is “\SERVER\Disco_C\rds.txt”
…on the local network LAN, not locally -
@Mirko-Rossi said in Macro script when txt content changes:

Yes. I was worried that it was going to be extremely long. That one is of a moderate length so that it would not be too difficult for someone to reverse engineer what it does.

…on the local network LAN, not locallyDo you mean
\\SERVER\Disco_C\rds.txt
? (the forum treats\\
as an escaped backslash, so only displayed one)[macro contents…]
it’s enough?That is the macro code, yes, so that can be translated into equivalent PythonScript commands.
But I think you still haven’t responded to when @Ekopalypse asked,
What puzzles me a bit is the document monitor, when it is on, the document is read-only from the Npp point of view, isn’t it? If you are willing to explain in more detail what needs to be done, …
In case you didn’t understand, often times with document-monitoring turned on, the file is marked as read-only, so that Notepad++ cannot edit it while it’s being written to by some external process. Otherwise, you get in the dangerous condition where both the external process and Notepad++ both try to write the file to disk at the same time. It might be nice to know how often the external process writes to the file, because that might influence whether or not there’s enough time to safely run your commands and save the file before the next time that the external process writes to it. (Then again, since you seem able to run the macro manually between refreshes, without adverse effects, it’s probably okay for the script, too.)
The process you want, as I understand it:
- The Document Monitor plugin will be used to refresh the contents of the editor window periodically
- You want to check the contents after such a refresh, and see if the contents have changed
- If they have changed, run the Macro you listed (or the equivalent translation into Python Script commands), then save the file
- Repeat ad infinitum
Please answer about “read only” status, and please add any additional details not captured in my summary of the process. After that, there will probably be enough for someone who understands @Ekopalypse’s SC_MOD_INSERTCHECK suggestion to implement a possible script.

Here’s a hint:
the txt is updated every song change
I’m envisioning a DJ type situation, including disco ball…roughly 3 minute songs. Could be totally wrong, though!

Ok, I misunderstood what was meant by “Document Monitor”.
I assumed we are talking about this oneSo, as @PeterJones already mentioned, this one is generating a buffer activated event, which means your could do something like this
from Npp import notepad, editor, NOTIFICATION import hashlib def md5sum(): return hashlib.md5(editor.getText()).hexdigest() def on_buffer_activate(args): global CURRENT_HASH if args['bufferID'] == FILE_TO_BE_MONITORED: NEW_HASH = md5sum() if CURRENT_HASH != NEW_HASH: CURRENT_HASH = NEW_HASH notepad.runMenuCommand('Macro', 'YOUR_MACRO_NAME') FILE_TO_BE_MONITORED = notepad.getCurrentBufferID() CURRENT_HASH = md5sum() notepad.callback(on_buffer_activate, [NOTIFICATION.BUFFERACTIVATED])
You have to give the document, which is monitored, the focus and run the script. I how this does what you want it to be done.
If you are running a localized version of npp, you need to replace Macro with the localized name.
-
it seems not to work.
I created and ran the script from the plugin menu. Am I wrong some steps?This is the script code:
from Npp import notepad, editor, NOTIFICATION import hashlib def md5sum(): return hashlib.md5(editor.getText()).hexdigest() def on_buffer_activate(args): global CURRENT_HASH if args['bufferID'] == FILE_TO_BE_MONITORED: NEW_HASH = md5sum() if CURRENT_HASH != NEW_HASH: CURRENT_HASH = NEW_HASH notepad.runMenuCommand('\\SERVER\Disco_C\rds.txt', 'intero') FILE_TO_BE_MONITORED = notepad.getCurrentBufferID() CURRENT_HASH = md5sum() notepad.callback(on_buffer_activate, [NOTIFICATION.BUFFERACTIVATED])
@Ekopalypse said in Macro script when txt content changes:
notepad.runMenuCommand('Macro', 'YOUR_MACRO_NAME')
i think i didn’t understand how to compile
-
\\SERVER\Disco_C\rds.txt
is the file which is monitored, correct? Andintero
is the name of the macro?If so, call
notepad.runMenuCommand('Macro', 'intero')
but only, if Macro is the name of the menu. -
ok, it starts up but doesn’t work properly. The macro, if called manually, works correctly; if called via script (automatically) it compares badly.
I write an example…
Original txt, starting: “Shake you down - Gregory Abbott”
This is the result with the automatic script: Shake you dow - regory Abbott
This is the result if I run the macro manually: Gregory Abbott - Shake you downstrange, right?
thanks -
another example
txt original: “No woman no cry - Bob Marley”
no script: Bob Marley - No woman no cry
with script: No woman no cr - ob Marleydeletes one more character, next to the final leading quotes "
-
that is strange, indeed. May I ask you how exactly you did it?
I expect the following:- The file \SERVER\Disco_C\rds.txt is open in npp.
- You start the document monitor
- You start the script via the PythonScript menu, BUT only once. If you call it multiple times, the macro will be called the same number of times. I should have mentioned that before, sorry.
For testing, open the PythonScript console (via menu) and run
notepad.clearCallbacks()
after each try to be sure that no
callback is active anymore. Or add this line beforenotepad.callback(on_buffer_activate, [NOTIFICATION.BUFFERACTIVATED])

ahahah you are right :) The title and the interpreter are reversed twice … I should have guessed it.
It seems to work perfectly.
now, I just have a txt encoding problem but that goes beyond this postthank you all
