Thank you very much for replies and sorry for bumping up - I didn't realize that... I finally wrote some functional code (it isn't perfect but for my purposes it is enough) so I want to publish it, maybe it will be helpful for someone...
So this convert comments in some source file from /* */ style to one-lined // ... Here is some commentary for every line:
1) Put newline after */ of every comment
2) When there is one-lined /* */ I change /* to //
3) If there is some multiline comment starting after code -> put newline (for simplify)
4), 5), 6) Putting // before multiline comments
7) Change starting /* in multiline comments to //
8), 9) Get rid of additional */ and //
It ain't that difficult, and definitely not so verbose -
Code:
$
$
$ cat -n testfile
1 first line here...
2 /*
3 inside comment - line 3
4 inside comment - line 4
5 */
6 line number 6
7 line number 7
8 /* a single line comment inside multi-line markers */
9 line number 9
10 /* and some more comments here
11 and here
12 and here - this being the last line */
13 line number 13
14 last line - number 14
$
$
$ perl -lne 'BEGIN{undef $/} while (/(\/\*.*?\*\/)/msg){print "\nMULTILINE COMMENT NUMBER ",++$i,":\n",$1}' testfile
MULTILINE COMMENT NUMBER 1:
/*
inside comment - line 3
inside comment - line 4
*/
MULTILINE COMMENT NUMBER 2:
/* a single line comment inside multi-line markers */
MULTILINE COMMENT NUMBER 3:
/* and some more comments here
and here
and here - this being the last line */

Hi !
I try to change a time-stamp hh:mm:ss allways to full ten-minutes.
example: 12:51:03 to 12:50:03
sed 's/::/:{0-5}0:/g' file.txt
but it will not work propperly, because the minute-decade will be replaced with the bracket-term {0-5}. Can someone please give me a hint?
Thanks in... (6 Replies)
I need to use sed to remove comments from files. I am using this, but it only works on comments that start at the beginning of the line.
sed /^"\/\/"/d
In most of the files I have comments like this:
code // Comments
or
tab // Comments (5 Replies)
I must write a script to change all C++ like comments:
// this is a comment
to this one
/* this is a comment */
How to do it by sed? With file:
#include <cstdio>
using namespace std; //one
// two
int main() {
printf("Example"); // three
}//four
the result should be: (2 Replies)

my desired output is like this:
so the thing is, I only need to show every of this part out
but the frequency of that data is not fixed, so sometimes it may have 4 lines, or 6 lines or whatever in that file. However, the last line will always have empty space/line below it. (13 Replies)
