Re: FC6 gvim version 7.0.235 question
Thanks Tim. I'll check it out, Sean Tim Chase wrote: I am running gvim version 7.0.235 on FC6.

While I don't know enough about your setup to give exact answers, I suspect this might be a window-manager issue. I have Fluxbox (my window manager here) set to control the Z-depth of various windows so that some windows/apps always appear above or below other apps. I don't know if somehow you've toggled such an option for either you gvim (a "bottom layer" setting) or for your terminals (an "above normal layer" setting), but that's where I'd start looking. This might have even been changed accidentally in one or the other by a keystroke you didn't know changed the z-depth. My "keys" file in Fluxbox allows me to map a keychord to "raise" and "lower" the current window (currently Win+PgUp and Win+PgDn). You may have unknowingly hit such a keychord in your window manager. -tim -- Sean Hubbell dBSTM Product Manager / Technical Director deciBel Research Inc. (256) 489-6198 (Work) (256) 426-8957 (Cell)
FC6 gvim version 7.0.235 question
Hello, I am running gvim version 7.0.235 on FC6. I have a slight problem where everytime I open a gvim session, the gvim window is placed behind all of my terminals. Would anyone have an idea why this is happening and how I may correct it? Thanks in advance, Sean
Re: startup extremely slow
I would guess and suggest to look at NIS authentication. Does the time it takes to open the file in another editor take as long? Sean Jagpreet wrote: Hi There, I use putty to connect to remote server with telnet. Not using the graphics version because of high speed with consol version. In the recent time I have started working some other remote server and I copied all my vim data(.vimrc, .vim) to this server as well. When I use vim command to open a file it is extremely slow in opening the files. Sometimes the time to open the file is almost 90 seconds. Please suggest where the problem can be. Regards, Jagpreet
Mapping to search Google Code
Hello, I seem to be oblivious to what I am doing wrong. I have the following mapping I would like to execute from vim: nmap :!"/usr/bin/firefox 'http://www.google.com/codesearch?hl=en&q=+'" I can execute the following from ex, but I am missing something from the mapping, does anyone have an ideas?

Question on highlighting
Hello, I would like to be able to shade (use the same background color, but make it lighter) the text between two braces (spanning multiple lines and possibly nested). What is the best way to accomplish this? Thanks in advance, Sean

I hope you don't mind a non-vim solution, but I used to run into this
problem all the time when I wanted to match tabbing for debugging/status
messages that would come to the screen. I just got so sick and tired of
hopping through the code to add a tab here, remove a tab there, etc.,
that I'd just bunch together all the string constants in one place, at
the top. Eg:
const char
*msg_help[] = {
"usage: %s [-options] [infile [outfile]]\n",
"\toptions:\n",
"\t\t-h\thelp\n",
"\t\t-l\tlong (detailed) output\n",
(const char *)0
};
const char
dbg_rdferr[] = "%s: cannot open \"%s\" for reading\n",
dbg_wrferr[] = "%s: cannot open \"%s\" for writing\n",
...
and have everything even visually aligned in one place. Would also let
me "reuse" the same strings as needed (eg, "%d" as an input to sscanf(),
"%02X" as a 2-digit output to fprintf(), etc.) without having to wonder
if I mistyped something that would only break when some rarely-used
piece of code would run.
Then, once all your strings are in a row, just look for
\n"[,;]$
and every string with the necessary newline at the end should be
highlighted. Any string that's *not* highlighted (ie, would be missing
the trailing newline) would, umm, would *not*, stand out.
Granted, that's not a vimmy solution to your problem, but it's a little
habit I got myself into, and for me at least, it made life a little
easier.
Any help?
Yes, I'l try it.
Thanks,

and I need to format it as so:
print ("small string\n");

Ideally, I would like to do this in one command and I would also like
to understand the regex itself. So, given the above, here is what I
understand of the regex pattern:
%s/print\s*(\s*"[^"]*\(\\n\)\@print\s*(\s*" - my phrase to match including zero or more matching
spaces at the end print, then a literal paren then zero or more
spaces up until the quote
[^"]* - then everything that is not a quote (zero or more)
Doing well up through here...
( - The beginning of the group ???
\\n - literal \n
) - End group
\@
You've got the understanding right (though those parens are "\(" and
"\)" with backslashes). Those four lines in concert assert that a
literal "\n" doesn't come before the current point. Without the
grouping, it would only assure that the previous atom (in this case,
the "n") didn't appear here, so you'd have problems with things like
print("terminal n")
because it sees the terminal "n" so it doesn't do the substitution.
By grouping them, you assert "and when you get to this point [before
the closing quote] and there isn't a literal backslash-en here, then
we match"
In here, you're missing the "\ze" which means "when doing the
replacement, treat it as though the thing we're substituting ended
here, even though there's more stuff we're looking for (namely, the
double-quote that's next)"
" - my ending quote to match in the pattern print ("")
correct
/& - ???
This is standard substitution...the slash is the break between the
search and its replacement. The ampersand is "the whole previous
match". In this case, it's slightly tweaked because of the "\ze" that
we used...the thing we replace goes up through (but not including) the
second double-quote. So it drops in everything from "print" through
the end of the internal string (sans-closing-quote)
\\n - literal \n
correct...appending the literal \n you want.
/ - delimeter
g- each occurrence on the line
Then we have the spanning multiple lines option:
\_ [^"]*
that's
\_[
not
\_ [
\_ - match text over multiple lines (Is this like another
regex engine, like the one sed uses?)
It's a vim thing:
:help /\_
should drop you in the fray. It prefixes (infixes?)a number of atoms
that could include whitespace, so for your change, you'd likely want
to do something like change the \s atoms to \_s to include newlines.
Does this make since? The area I am having difficulty with is /& and
how the grouping is working.
Hopefully this sheds some light on matters and helps you tweak your
own regexps in the future. If you have any questions, feel free to ask.

Yes, this helps greatly. Thanks again Tim.

Re: Regular Expression Question
print("This is 1.\n");print("This is 2.");
print("This is 3.\n");
I would like the above to be formated like (which is just adding in
the newline a print that may not have it, but only if it does not
have it):
print("This is 1.\n");print("This is 2.");
print("This is 3.\n");
I presume you mean that second section to read
print("This is 1.\n");print("This is 2.\n");
print("This is 3.\n");
adding in that "\n" after "2."
On the assumption that you don't have quotation-marks escaped in your
strings such as
print ("She said \"hello\" to me");
you should be able to do something like
%s/print\s*(\s*"[^"]*\(\\n\)\@which should catch most of the non-pathological cases. If quotes can
span lines, such as
print ("this is a
really long string")
then you can change
[^"]*
to
\_[^"]*
I just noticed that I also need to support the following as well:
print ("small string");
print (
"This is a very long string");
and I need to format it as so:
print ("small string\n");
print (
"This is a very long string\n");
Ideally, I would like to do this in one command and I would also like to
understand the regex itself. So, given the above, here is what I
understand of the regex pattern:
%s/print\s*(\s*"[^"]*\(\\n\)\@
% - globally
s - substitute
/ - delimeter
print\s*(\s*" - my phrase to match including zero or more matching
spaces at the end print, then a literal paren then zero or more spaces
up until the quote
[^"]* - then everything that is not a quote (zero or more)
( - The beginning of the group ???
\\n - literal \n
) - End group

Regular Expression Question
Hello,
I have the following question. Given several lines in a file that look
like the following:
print("This is 1.\n");print("This is 2.");
print("This is 3.\n");
I would like the above to be formated like (which is just adding in the
newline a print that may not have it, but only if it does not have it):
print("This is 1.\n");print("This is 2.");
print("This is 3.\n");
How does one do this?
Sean
