reGex Find copy and replace to a new line.

Evangelos Kosmas

Hello.
I need help in a regex syntax to be able to transform the gcode for my CNC machine

The following is a sample of gcode, my machine cannot read or execute.

Numbers at the beginning of each line, are not really exist in code.
I added them just for this post.
AND
Line1 means Program Start and line40 program end.
Lines 2 to 16 are usefull for the machine.
Lines 17 to 29 are notes for the user.
All these LINES (1-29) have to stay as they are.

The real code machine executes is in lines
30 and 31
32 and 33
34 and 35
36 and 37
38 and 39

Here is the sample code

%
|1 P3002
|2 0
|3 13
|4 180.00
|5 44.30
|6 180.00
|7 0 0 0 0
|8 0
|9
|10
|11
|12
|13
|14

G172 X-74.305 Y-52.511 Z0.000 S17 E2 T7
G100 X-74.305 Y-52.511 Z10.03 F1
G172 X-74.305 Y-37.496 Z0.000 S17 E2 T3
G100 X-74.305 Y-37.496 Z11.000 F3
G172 X-74.305 Y-23.338 Z0.000 S17 E2 T3
G100 X-74.305 Y-23.338 Z12.000 F1
G172 X-74.734 Y-11.326 Z0.000 S17 E2 T9
G100 X-74.734 Y-11.326 Z12.000 F4
%

Lines 30,32,34,36,38 (starting with G172) are useless. I have this regex ^G172.*\R to delete them and move the following line (starting with G100) one up.

But in these lines (starting with G172) there is one information i must keep before deleting.

In line30, i need the last digit wich is number 1
or the last 2 digits T1
In line32, i need the last digit wich is number 7
or …T7
In line34, last digit is number 3
or…T3
In line36, number 3…or T3
In line38, number 9…or T9
This number is always a digit between 1-9.

I can mark them with several ways but i prefer this
(?<=T)\d$ cause it has no effect on other lines.

What i need is to copy digit 1 from line30, paste it to the end of the next line (line31) including a space and letter T in front of this number and then delete line30 and move 31 one line up.
or
to copy last two digits from line30, T1 and then paste them at the end of line32, including one space before them, delete line30, move line31 one up.
It is also necessary to replace same way to the next lines of code.
T1 form line30 to the end of line31
T7 from line32 to the end of line33
.
.
.

So
Old format was
.
.
30. G172 X-74.305 Y-67.956 Z0.000 S17 E2 T1
31. G100 X-74.305 Y-67.956 Z15.220 F2
32. G172 X-74.305 Y-52.511 Z0.000 S17 E2 T7
33. G100 X-74.305 Y-52.511 Z10.03 F1
34. G172 X-74.305 Y-37.496 Z0.000 S17 E2 T3
35. G100 X-74.305 Y-37.496 Z11.000 F3
36. G172 X-74.305 Y-23.338 Z0.000 S17 E2 T3
37. G100 X-74.305 Y-23.338 Z12.000 F1
38. G172 X-74.734 Y-11.326 Z0.000 S17 E2 T9
39. G100 X-74.734 Y-11.326 Z12.000 F4
40. %

And the New format must be like this
.
.
30. G100 X-74.305 Y-67.956 Z15.220 F2 T1
31. G100 X-74.305 Y-52.511 Z10.03 F1 T7
32. G100 X-74.305 Y-37.496 Z11.000 F3 T3
33. G100 X-74.305 Y-23.338 Z12.000 F1 T3
34. G100 X-74.734 Y-11.326 Z12.000 F4 T9
35. %

Thanks in front

As your example has been altered (by you adding line numbers) and possibly by the posting engine as you did not put the example inside of a black box (see this FAQ post) my solution may or may not work. I’m hoping it will as the regex you provided for deleting the G172 line does help.

So using the Replace function we have:
Find What:(?-s)^G172.*(T\d)\R(.+)
Replace With:\2 \1 note there is a space between \2 and \1.
So I just extended what you already had, including the T digit portion on the first line, also selecting the entire second line and then writing back the portions you wanted to keep.

See if it works and please do come back to us either way. if you need to post further examples please read that FAQ post I linked to above.
