syntax for filename + line number

[mobi phil]

Hello,

lot of programs (gdb, gcc) have as output information about file and
line in form of

<filename>:<number>

I wonder if it would not be clever to make vim accept such a syntax
for opening file.
Eventually with a flag that would switch on/off this syntax.

This would be interesting both when opening a file:

vim <filename>:<number>

or internally

:new/edit/split <filename>:<number>

I know that you can specify in both forms the line number separatelly
with +<linenum>, but
the proposed form is much more handy if you copy paste info from
commands like the mentioned
ones

thanks for your attennion,

I don't think adding this syntax is a good idea, as it conflicts with opening named data streams on Windows. It also could conflict with drive letter syntax if <filename> is a single alpha character.

I am affraid everything what is in IT is conflicting with Windows :) .
That should not stop IT to evolve.
There are tons of settings that differ from **x to windows. Some of
the behaviour is automatically
changed some are switchid with variables. The same can happen with this one

This can be achieved via an autocmd; in fact, the file-line plugin provides this
functionality:

Vim has already two built-in mechanisms of this kind:

1) for a one-time opening of a file at a given position, see ":help +cmd"

:e +123 foobar.txt
open foobar.txt at line 123

:e + foobar.txt
open foobar.txt at end

:e +/pattern foobar.txt
open foobar.txt at the first line matching /pattern/

:e +/pattern\ with\ spaces foobar.txt
spaces must be backslash-escaped

etc.

2) if your program generates a number of such file-locations, like grep
does, or like a make run with a number of errors and warnings: see
:help quickfix.txt
:help :compiler
:help 'errorformat'
etc.

Best regards,
Tony.

Hello,

Thanks for describing the 2 ways. I am not happy if I would disappoint
you for writing that down, but I was aware about those.
What I was a bit annoyed, is that a format that is output of several
commands used everyday by most of us, is not accepted as "standard"
command line. I have created for myself a wrapper that converts
file:line into file +line.

So my wrapper is wrvim and
wrvim file:line
is the same as
wrvim file +line

Why don't you use the file-line.vim plugin? I mentioned it a month ago in
exactly the current thread:
http://groups.google.com/group/vim_dev/msg/722aefe8494c3a44

when I tried that plugin last time, I must have made some mistake when
installing it, did not work. As you insisted, I tried it again, and:

IT WORKS :), so thanks.

However my wrvim still makes sense as it always knows what to open, for example:

(alias vi=wrvim)
->vi my life



Thanks again, Ingo, Tony, Craig
