Tip #487: jump to a file to a certain line number

Dear VIMMERS:

It is useful to have cn, cl for locating errors. however, when the compilation was done off-line,
gcc  ... >& compile.log
how to use the compile.log to locate the errors? for example,
     vim.h:1506
if i use "gf" when the cursor is over "vim.h", it just jumps to the begining of the file.
here may be one solution by combining several steps:
      nmap gt mAT f:l"aywbbgf:^Ra^M
"mA"   --- marks the current position to global register A so that i can return the log file by 'A
"T "     --- goes to the begining of the tag, so in any characters of "vim.h:1506", it first places the cursor to "v".
"f:"      --- goes to the ":" separator
"l"       --- goes to the starting of line number
"ayw   --- try to use register a to remember the line number
"bb"    --- move cursor back to the filename
"gf"     --- now jump to the file
":^Ra^M"
          --- jump to the line number remembered in register a

nmap gt ... place the above steps into key combinations "g" "t" so next time use "gt" instead of "gf" on the error tag!

<<Search for word under cursor, but don't move. | vimrc setting for wider vim diff window (gVim) >>
