retab lines matching regular expression

2009-09-16 Thread Hoss

What I would like to do is retab all lines in the file matching a
given regular expression. Here's what I've tried

:g/^#/ret! 100

however this is simply retabbing the entire file.

But if I say

:g/^#/d

it only deletes the specified lines.

How do I make it work?

Okay. Not trying to seem belligerent or anything, but, as I said, it
actually does not work for me. You're explanation makes sense, but
I've tried it several times. When I place the (.) before (ret), I get
no replacements taking place at all. Im using vim 7.1 in a terminal on
Ubuntu.

Any ideas?

Re: retab lines matching regular expression

2009-09-16 Thread Hoss

Okay, now that I'm playing with my settings im getting really
inconsistent results that I cant really explain.

If I open up a new buffer, with the following two lines in it

good tabs
#bad tabs

the command seems to work exactly correctly, whether my ":set et", or
my ":set noet" is active

However, in the actual buffer where I'm trying to do this (its been up
for several hours) this isn't the case.

Like I said, it wasnt working here at all. But after I toggled my
":set et" and ":set noet" it seems to operate the same way regardless
of which one is set. But it isnt doing quite what I want. Its only
replacing the tabs on the lines I want it to; however, the new tabstop
seems to be applied first. So, if the line opens with "#text",
after the command I have "#<100 spaces>text"

> Just to confirm, what are your relevant settings?
>
>    :set et? ts? sts?

:set ts => tabstop=2
:set sts => softtabstop=0

I'm sure there are some more settings I just dont know about which
could explain this. Though I didnt set any special settings on my
buffer . . .

Confused,
Todd

Re: retab lines matching regular expression

2009-09-17 Thread Hoss

Gary,

let me explain what I'm trying to do in as simple of terms as
possible. Consider the following file

good tab
good tab
#bad tab
#bad tab
good tab
good tab
#bad tab
#bad tab

I want to run a command which will retab only those lines where it
says "bad tab". I match those lines with the regexp /^#/

I exactly reproduced your testcase, with precisely the same results.
Your explanation makes complete sense and I believe the entire
situation is clear to me now. The key is that the entire retab
operation is occuring N times (once per matching line) which includes
resetting the tabstop value.

Using Tim's suggestion, and going back to my original post, I am now
using the command

:g/^#/.ret! 100 | set ts=2

which resets the tabstop after each line. With this modification, it
works perfectly.

Thanks everyone for your comments.

if x is sufficiently large, then your columns will appear aligned.

tabedit with buffer number

2009-09-23 Thread Hoss

Suppose I have a buffer which is open and I know its number. What
command can I use to open a new tabpage with a single window with that
buffer open?

:help tab shows the ":[count]tab {cmd}" command which says it just
runs cmd and opens a new tabpage instead of a new window, but it
doesnt work for me.

If I say ":tab b 3" I just get buffer 3 opened in the current tabpage.

I'm not totally sure what you're asking for. However, I use the
ShowMarks.vim plugin which allows you to see where your marks are
placed, hilight the lines they are on if desired, clear all marks,

matching lines in window

Hi,

I know I used to know how to do this but I can't remember...

I have a regex that will match several lines in the buffer. Instead of
just / searching for it and N'ing through the file, there's a way to
execute the regex on the buffer and get a little sub window containing
1 line per match . . . how do you do that?

custom operator-pending mapping

2009-09-25 Thread Hoss

Can you create your own "operator-pending" mapping, similar to going
to a line number with "25G" ?

The specific thing I want to do is put in the number of a buffer, then
create a new tabpage with a window open on that buffer, something like

25ob -> open buffer 25

mapping alt-keys

2009-10-07 Thread Hoss

I am having trouble mapping my alt keys. so if I use this mapping

 :echo hihi

I get nothing when I hold down alt, and press g in normal mode.

I have read :map-alt-keys in the documentation, and it suggests
there's alot going on with getting the alt key from my keyboard to
vim.

My question is, is there some diagnostic mode in vim to somehow dump
the key data that is going into it, so I can figure out what the issue
is?

I am using:

This works excellently, except that I can't use exactly what vim
displays in my map command.

My  shows the same thing as yours. However, if I type ":map
 :echo hi" into a buffer, then execute that line, i get
garbage.

However, using the knowledge that the "^[" means escape as you say, if
I try this

map g :echo hi

then it works great.

Analog to SHIFT+Asterisk

2010-06-30 Thread Hoss
Esteemed Vim Users,

One of the useful key combinations in vim is shift+asterisk, which
will locate the word your cursor is "on", and put that word into your
"/ buffer (surrounded by \<\> word boundaries). This has the effect of
highlighting all occurrences of that word.

It also has the effect of jumping the cursor to the next instance of
that word in your buffer.

Is there an analogous key combination, that will highlight the current
word, WITHOUT moving my cursor?

Thanks,

Todd

(I know I can just shift+N afterwards, to get back where I was.
Something more elegant?)

Replace tabs with spaces - with a twist!

2008-10-13 Thread Hoss

I'm sure this is a familiar topic, but I can't find quite what I need
anywhere.

Say I have a line in a file with 4 characters followed by a
followed by 2 characters and a .
Say the tabstops are at positions 5, 10, 15, etc.

Then, when viewing this file, the first tab will be displayed as a
single space, since it aligns with the tabstop boundary. The second
tab will display as 3 spaces in order to align with the tabstop
boundary. Its kinda the whole point of tabs. Great.

What I would like to be able to do is replace all of these tabs with
the number of spaces by which they are being displayed. The first
would be 1 space, the 2nd 3 spaces, etc. So,

s/\t/   /g

will not work, because its the same number of spaces for each tab.

Thanks-
Hoss

Re: Replace tabs with spaces - with a twist!

2008-10-14 Thread Hoss

Looks like smart people thought of all this before me. Two things:

it would be nice if you could do :retab 20 (or some other sufficiently
large number, depending on how many consecutive tabs you have going
on) without changing the actual tabstop value. Not a big deal.

It would be nice if you could do the reverse operation, i.e. replace
spaces with the appropriate number of tabs according to a given
tabstop value so that visual positioning was preserved.

Thanks again

Re: regexp for grabbing everything between curly braces { }

2008-10-16 Thread Hoss

Justin,

It is not possible to formulate a regex that will match everything
between matching pairs of tokens ({, }) nested arbitrarily. So if your
function can contain any level of nested if/switch/other blocks
delimited on {} characters, regex will not do the trick. It's not too
complicated to write some code that will do it, however. What you need
is a stack data structure.

laggy scrolling / ubuntu

2012-04-19 Thread Hoss
I have been dealing with this issue for probably about a year, and I keep 
ignoring it, but it is actually super annoying so I've decided to post here and 
see if anyone has any ideas.

I'm in vim. I've got tabs and buffers open. I use CTRL+Y and CTRL+E to scroll 
up, and down, respectively. Now, when I hold down one of these key 
combinations, I scroll something like, I dont know, 20 lines, then theres a 
little "freeze", lasting maybe half a second. The effect is choppy scrolling. 
Same thing happens if I use the arrow keys to scroll, or CTRL+D or CTRL+U to 
scroll screens at a time.

Again this is not a make-or-break issue but I would like to figure this out if 
possible.

possibilities
 - internal vim buffering
 - keypress processing in the OS, or in VI, in my keyboard itself .. idk

I'm sure there are a dozen more possibilities.

Also - I experienced the exact same behavior on Ubuntu 9.10, its one of the 
reasons I upgrade to 11.10. Didn't change it though.

Okay ... this only happens when I run vim under tmux. It does not happen under 
gnome-terminal or xterm directly, or when running vim under screen.

Upgrading from Ubuntu 11.10 stock tmux 1.5 to tmux current 1.6 appears to have 
fixed the problem. Thanks everyone!

yank matched portion of a selection of lines

2012-07-06 Thread Hoss
I have a buffer open. I hit /, put in a search, and the matched text, which is 
the text I am interested in, is highlighted.

How do I yank that text, and only that text, in other words, not whole lines? 
Bonus points if I can also restrict it to a selection of lines, by number.

Ideally, the yanked text would consist of each match within the range, 
concatenated together with a newline between each. So, if each line only has 1 
match, this would coincide with an exact copy of the original lines, minus any 
non-matched text, if that makes sense.

I did try your second example but it doesn't seem to work out of the gate, and 
I'm not having any luck tweaking it.

:%g#top="[^"]#exec "norm! /top="[^"]\\"Ay//e\"
E15: Invalid expression: ^"]\\"Ay//e\"
E15: Invalid expression: "norm! /top="[^"]\\"Ay//e\"
