Add 'G1' to the start of each line.
-
Sorry noob here… I am writing a G-Code program for my home made cnc. My thing is I need to add ‘G1’ to the start of each line and as I have over 12,000 lines I don’t want to do each line in turn…
Is there a way to use find and replace to do this automatically?Any help would be great.

Hello, @cnc-builder
Elementary task with regular expressions, indeed !!
-
Move back to the very beginning of the file to change (
Ctrl + Origin) -
Open the Find/Replace dialog (
Ctrl + H) -
Type
^, in the Find what: box -
Type
G1, in the Replace with: box -
Choose the Regular expression search mode
-
Click on the Replace All button
Et voilà !
Notes :
-
The
^character is the symbol, meaning “beginning of line”, in regular expressions -
If you prefer to separate the string G1 from the rest of text, you may, either, add a space character after G1 or the symbol
\t, for a tabulation character

P.S. :
For newby people, about regular expressions concept and syntax, begin with that article, in N++ Wiki :
http://docs.notepad-plus-plus.org/index.php/Regular_Expressions
In addition, you’ll find good documentation, about the Boost C++ Regex library, v1.55.0 ( similar to the PERL Regular Common Expressions, v1.48.0 ), used by
Notepad++, since its6.0version, at the TWO addresses below :http://www.boost.org/doc/libs/1_48_0/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html
http://www.boost.org/doc/libs/1_48_0/libs/regex/doc/html/boost_regex/format/boost_format_syntax.html

The FIRST link explains the syntax, of regular expressions, in the SEARCH part
-
The SECOND link explains the syntax, of regular expressions, in the REPLACEMENT part
You may, also, look for valuable informations, on the sites, below :
http://www.regular-expressions.info
http://perldoc.perl.org/perlre.html
Be aware that, as any documentation, it may contain some errors ! Anyway, if you detected one, that’s good news : you’re improving ;-))
