Hi ppl,
In an HP/GL2 file, there is a command called SP (select pen) which is associated to a pen number from 1 to 64. I have to parse the file and insert a command after each select pen command.
Example :
10652PUPD515,10652PUPD515,2536PUSP61PU57531,8270PDPA57 ----
to : 10652PUPD515,10652PUPD515,2536PUSP61;NEW_COMMAND;PU57531,8270PDPA57 ----------------
How can I search for either one digit after SP (for pen numbers from 1 to 9) or two digits (from 10 to 64) ?
My actual way of doing it is : s/SP(\d*)/SP$1;NEW_COMMAND;/)
In the case mentionned above, the subtitution won't work. d* doesn't seem to be the correct way to search for digits after SP.
It has to find for one OR two digits after SP.
/SP(6[1-4]|[1-5]?\d)/
