Is there any alternative to Merge files in one plugin?

@Doğancan

OK, so essentially your problem is something along the lines of:

• Document A has text in lines ABEFJ
• Document B has text in lines CD
• Document C has text in lines GHI

We want a document that contains lines ABCDEFGHIJ from Documents A, B, and C.

This is very different from the problem we thought we were helping you with, and it would have been nice to know earlier.

That said, here is a PythonScript solution (see that link for info on how to use) that can solve this problem:

That said, here is a PythonScript solution (see that link for info on how to use) that can solve this problem:

Improvement to the above script, with an “escape valve” added to stop processing collisions in case there are so many that going through all of them would take forever.

@Mark-Olson It really worked. Endless thanks .Can you publish this as a plugin so that everyone can use it ?

Glad it worked! A plugin? No. PythonScript scripts have to be installed according to this link.

The closest thing I can provide is a Github gist .

@Mark-Olson I thought that plugins work with python.What programming language are notepad++ plugins written in ?

Notepad++ plugins are DLLs using a C interface, so any language that can be compiled to that could be used to write a plugin. In addition to “native” C or C++, the documentation links to API files for Ada, C#, D and Delphi.

@Coises
…and Pascal , V , as well as PythonScript-like plugins in Lua and JavaScript .

So far, besides what has already been mentioned, I have written plugins in Nim, Odin, Zig, Rust and Python (using cython and cffi). So basically it boils down to the language having to be able to create a native DLL that Npp can load.

@Doğancan This solution worked for me (I tried it on merging HTML files succesfully):

@Diego-Raguindin said in Combine Plugin Gone!?:

This worked perfectly for me:

Put all of the files you want to combine in the same folder. Easiest would be at root-level.
Run a command prompt
CD to the folder in Step 1
Enter command copy *.csv filename.csv where “filename” is the desired output filename
Hit enter
File ‘filename.csv’ is created in the same folder
