Given a file of source lines that look like the following, I would like to splice together lines with escaped new lines but preserve the line numbers. tomk
Input File
line(1) line(2)\ line with space after excape(3)\ line(4)\ line(5) line(6)\ line(7) line(8)
Solution
set fid [open [file normalize "./filename"] r] set text [read ${fid}] close $fid regsub -all -- {[\\][ \t]*[\n]} ${text} "\\\n" text while { [regsub -all -- {[\\][\n](.*?[^\\])[\n]} ${text} "\\1\n\n" text] } {}
Result
% puts $text line(1) line(2)line with space after excape(3)line(4)line(5) line(6)line(7) line(8) %
