How to get hints on compiler errors ? And jump into editor on error file and line ?

[akharrou]

Consider this:

❯ gcc -Wall main.c
main.c:6:3: error: implicitly declaring library function 'printf' with type 'int (const char *, ...)' [-Werror,-Wimplicit-function-declaration]
  printf("Hello world\n");
  ^
main.c:6:3: note: include the header <stdio.h> or explicitly provide a declaration for 'printf'
main.c:4:7: warning: unused variable 'bla' [-Wunused-variable]
  int bla;
      ^
1 warning and 1 error generated.

How can you get hints on just main.c:6 and open vim directly on that line ?

Bonus: can you additionally include columns in this ? i.e hint selection would include them and vim opens cusor directly in that file, on that line, on that column.

@kovidgoyal I tried this:

# kitty.conf

map super+y kitten hints --type=linenum --linenum-action=tab nvim +{line} {path}

on the exact compiler errors above ...but I keep getting "No matches found, press Enter to quit."

I also tried this:

# kitty.conf
map super+y _hints --linenum-action=window --type=regex --regex="\b(?P<filepath>.+):(?P<line>\d+)(:(?P<column>\d+))?" --program="nvim +{line} {filepath}"

Which gives me matches on more than just what I need, by matching the command prompt paths, and doesn't seem to do anything once I select a hint... something wrong with my usage of --program ?

So I also tried removing --program … like in other examples...

# kitty.conf
map super+y _hints --linenum-action=window --type=regex --regex="\b(?P<filepath>.+):(?P<line>\d+)(:(?P<column>\d+))?" nvim +{line} {filepath}

...but that doesn't work either and I get: "Extra command line arguments present: vim + (line} {filepath} Press Enter to quit"

main.c cannot be matched by the default rules (ext 2~7). This issue has also been on my list for a while.

def linenum_marks(...)
    # ...
    regex = r'(?P<path>(?:\S*/\S+?)|(?:\S+[.][a-zA-Z0-9]{2,7})):(?P<line>\d+)'

@kovidgoyal
Is there a negative impact if we add single-letter c, h, m files?

Should be ok to add aother branch to the regex of the form: (?:\S+[.][hcm])
