Re: Print column of search result

Thank you. I understood.

Since Global is a line oriented tool like grep(1), its DB don't have column

information.

So, you have to write a program to know column information.

[global's output]

arg                 6 multiple-users.c  func(arg(), arg());

[program]

pattern = "\\barg\\b"           // \\b matches to a word boundary

line = read a line at 6 in multiple-users.c.

regex_t reg;

regmatch_t m[100];

regcomp(&reg, pattern, ...);

regexec(&reg, line, 100, &m, ...);

As the result, the 'm' array has column information.

int arg() { return 42; }

void func(int x) { }

int main() {
  func(arg(), arg());
}

$ global -r -x arg
arg                 6 multiple-users.c  func(arg(), arg());

OK so this actually even worse for script usage than expected:

* The usage of `arg` is displayed only once
* The code context shown doesn’t start at the place/column `arg` is used but somewhere else

What I’d like to see is an output like this:

$ machine-readable-global -r arg
6:8,13
6:15,20

These are the line, start and end column numbers.

Is there some easy way to extract this information directly from the DB?

Thanks
Jonas
