[feature request] Syntax highlighting for OpenCL (*.cl) kernels

[nickreserved]

Title is self explanatory.
OpeCL files are like C with some extra keywords like '__kernel' , 'kernel', '__global', 'global' etc.

Could you add ; cl in "Customize Schemes..." (see picture) and let us know if this matches your request?

[nickreserved]

Yes of-course it works as C, but the OpenCL C API have more keywords than C.
For instance '__kernel', '__global', '__local'.

Probably notepad3 uses a 3rd party library for code highlighting.
If that library supports OpenCL C API it would be great for notepad3 to also support it.
If not, never mind!

Hello, I can add the "CL" extension and associated keywords in "C/C++ Source Code" Lexer.
Can you provide me with a list of CL keywords you want to add or the site where I can find them? 🤔
And if possible a "test file"?

[nickreserved]

ok. Leave the ticket open because I must scan the full spec (it needs time).

I think you don't want predefined functions / macros.

Hello, I can add the "CL" extension and associated keywords in "C/C++ Source Code" Lexer.

The above statement is not correct because it is not possible to add OpenCL keywords to the "C/C++ Source Code" lexer.
If you want to have an "OpenCL" lexer in Notepad3, you must first ask Scintilla.org to create it in Lexilla Lexers.
See: https://github.com/ScintillaOrg/lexilla

Did you try in ChatGPT:
Can I extent scintilla lexer of C99 with some OpenCL keywords? E.g. how can I have a new lexer based in C99 with 2 extra keywords "__kernel" and "__global"?

Hello @nickreserved ,

Feel free to test the "BETA PortableApps", version "Notepad3Portable_6.25.203.1_beta.paf" or newer, see 1st list in issue #1129.

• Notepad3Portable_6.25.203.1_beta.paf.exe.7z -s

"Notepad3Portable BETA PortableApps" version can be used with or without ".7z" extension.

Also, feel free to test the "BETA Setup", version "Notepad3_6.25.203.1_beta_Setup" or newer, see the 2nd list in issue #1129.

Comments and suggestions are welcome... 😃
