Need help for CNC code.
-
Greetings to everyone! I’m a newbie here, hoping to get some answers to a few questions. I began CNC programming using Solid Works 2018, a program designed for writing CNC code with a generic post-processor. I want to share my problem with you.
(Generic text “GENERIC TEXT” GENERIC TEXT, )
(GENERIC TEXT, generic text. )

This is my problem.
I have a recurring issue with the beginning and end of my code. I always have to replace the generic text with ‘%’ and manually add an ‘E’ at the end of the program whenever I rewrite it. Is there a way to automate this process?
Whenever I get a new program, I have to correct F400. F200. (or any Fxxx. not to have a period at the end of Fxxx). Can I automate that as well? -
@Radomir-Stojanović - I believe this article applies FAQ: You’ve asked your question in the wrong place!
This forum is for supporting the Notepad++ text editor, and to a lesser extent, the regular expression system implemented by Notepadd++ plus some of the Notepad++ plugins.

I think this is the right place for this question.
It is about how to transform this text:
into this text:
Note that I’ve intentionally shown the two texts as a “diff”.

Whenever I get a new program, I have to correct F400. F200. (or any Fxxx. not to have a period at the end of Fxxx). Can I automate that as well?This can easily be done with 3 regular expressions (regex), however the 3rd one won’t be completely sorted, I will speak to that later.
So using the Replace function we have the first one which deals with the “generic text issue”.
Search mode must be regular expression for all 3 regex I’m showing.
Find What:(?-s)\A(\([^)]+\)(\R))+
Replace With:N0 %${2}
Click on Replace AllNow we deal with all the Fxxx. sequences.
Find What:(F\d+)\.
Replace With:${1}
Again click on Replace AllFinally the end line for the code. The primary problem here is that regex cannot count. So there isn’t an easy way for the regex to add 1 to the last line and write a new line with the incremented number and and E. So what my regex does is to write it with xx as the line number. So you would still need to change the xx for the real line number. Although I have provided this regex, I think it would be of limited value as you would still need to edit that last line.
Find What:(?-s)(\R).+\K\z
Replace With:${1}Nxx EThese 2 (or 3) regex can be combined into a macro which is essentially the keystrokes recorded as you type them and once saved (with a name) can be re-run whenever you wish.
