I agree there's a problem. I think vim.org could do with
some modernising.

A wiki is a great idea. And they maintain themselves,
courtesy of those who give a shit. I think it should be on
vim.org though (I realise this is your ultimate intent too).

Agreed. These questions come up *a lot*, and finding the
answers with Google is surprisingly difficult. What you get
are blog posts saying 'you can hack foo integration into Vim
with these custom mappings which happen to rely on custom
program x which is in my environment but you'll have to
compile it from source ...,' etc.

This isn't a criticism: because Vim is so customisable,
people can easily whip up their own systems which solve the
problem at hand but aren't always helpful for the beginner
(or seasoned professional!) trying to learn Python, for
example.

The current state of affairs is quite fragmented.
There's vim.org, the mailing list, the Vim tips wiki,
scripts on vim.org, other scripts on Github, discussion on
#vim, many questions on Stack Overflow .... Where to look?

Certainly I think the scripts section on vim.org needs
a thorough revamp.

> Feedback about this idea and ideas are welcome.

Well, I also think that vim.org would benefit from
a chatroom, Stack Overflow style. I've no doubt it
would be popular among new users of Vim. #vim has
loads of new users asking questions, and who uses IRC
these days? :-)

I think, given the enduring popularity of Vim, it needs
a centralised resource.

Thanks, Charles. I'm going to put this on my to-do list (my real one,
which I do manage to chip away at) for the time being. Need to figure
out this dropping in of new plugins.

Try v147g of netrw from my website:
http://www.drchip.org/astronaut/vim/index.html#NETRW .

Seems to be something I'd overlooked. The method now:

mt in the banner sets the target directory to the current window's
current directory
Unless it already is the target directory, in which case the
target is removed.

netrw: unmark target directory for copy/move

In netrw, is there a way to unmark a targe directory for copy/move?
The display of the target directory is taking up valuable real estate

Re: vim edit help

First, the explanation. See the references that Ben Fritz already listed.

/Array<CR>: Search for the text "Array". Do not type <CR> literally: it means hit Enter or Return.

ciw: Change the word (text object). You could also use cw or ce (change word or change to end)

dojox.collections.ArrayList: This will be added to the buffer, since you are in Insert mode after ciw.

<Esc>: Leave Insert mode. Do not type it literally.

As for doing it 11 times, I would record a macro, starting before the search command and ending after the :s command. Roughly, if I want to use the x register for the macro (qx)

/Array<CR>

ciwdojox.collections.ArrayList<Esc>

^w"yye
f(
dib
o<Esc>
p
:s#"[^"]\+",\?\s*#<C-R>y.add(\0);\r#g

(Note that I have yanked into the y register instead of typing the word "illness" literally.) If all of the works, then you can repeat it with

8@x

:help recording

Here regular expressions are your friend.

I'd start by changing the "new" line to be correct:
/Array<CR>
ciwdojox.collections.ArrayList<Esc>
f(
dib

Now paste the deleted list of initializers on a new line and put it in the right format:
o<Esc>
p
:s#"[^"]\+",\?\s*#illness.add(\0);\r#g

Done!

All this is untested but it's pretty straightforward so you should be able to fix it.

Re: ctrlP to navigate arbitrary directory

thanks for the quick response.

I did try .. and ../ but didn't try ..<cr> . :)

So when CtrlP started, I can only stay at project directory. or ../../../......../../ <enter> to root :)

i think i have to get used to it if I use it.

You can't navigate to an arbitrary directory once CtrlP is up, but you can invoke CtrlP on an arbitrary directory, e.g.:

Scratch that... The help tag has been removed in recent versions
(wtf?), though the command remains.

It's equivalent to CtrlP with the ctrlp_working_path_mode of 1.

ctrlP to navigate arbitrary directory

Hello,

I use FuzzyFinder for years. Recently I heard a lot about CtrlP. And gave it a try. It does have some good features over FF. However one thing I didn't figure out, with FF(File search), I can type "/etc" to navigate to my root directory and do search, no matter which directory I am in.

However for CtrlP, it seems that it searches only under current directory. In doc I found I can type .. to go to parent dir. but it didn't work for me somehow.

How can I navigate to arbitrary directory with CtrlP?

thanks.

It might be easier to set the grep alias apropriately. It sounds, the
grep alias appends the --color=always which in this case causes the
problem. You probably want rather --color=auto so that grep does not
color output, that is not displayed on a terminal.

Re: Search Patterns

John Lusby <jlusby42@gmail.com> a écrit :

That worked almost perfectly. The only problem with this one is that the files that are in the working directory aren't proceeded by a slash. I gather that the pattern you gave is for ^ followed by any number of non / characters. I guess I got confused and thought that * was itself a wild card.

Thank you very much Christian. I've figured out what I needed and more. With your start and a bit of googling the right answer ended up being :%s/^\S*\s//. Another source of confusion had been that I didn't realize >> was append so I was sometimes opening files and not realizing I was seeing outputs from different versions of my command. The proper output from just the grep with no modification was just

[01;31m [Kpreprocessing [m [K /home/john/local/tinyos-2.x/tos/chips/msp430/McuSleepC.nc
[01;31m [Kpreprocessing [m [K /home/john/local/tinyos-2.x/tos/interfaces/McuPowerState.nc
[01;31m [Kpreprocessing [m [K /home/john/local/tinyos-2.x/tos/interfaces/McuPowerOverride.nc

[01;31m [Kpreprocessing [m [K gridEyeAppC.nc
[01;31m [Kpreprocessing [m [K /home/john/local/tinyos-2.x/tos/system/MainC.nc
[01;31m [Kpreprocessing [m [K /home/john/local/tinyos-2.x/tos/interfaces/Boot.nc

[01;31m [Kpreprocessing [m [K /home/john/local/tinyos-2.x/tos/interfaces/Init.nc

The pattern you gave me worked great for every pattern except the ones in the current directory because they didnt have a /, but thats my fault because I linked a portion of the list that didn't include that. Thank you again

Looks like your make program outputs terminal sequences to e.g. display
colors? Try explicitly setting your terminal to somthing dumb for make.
It shouldn't then output those chars:
TERM=vt100 make ...

Your pattern doesn't look right btw. I think what you want to search for
is :%s/^[^/]*//

Your pattern ^*\/ is actually looking for line start followed by a '*'
followed by a slash, which is obviously not what you need.

Christian

As Christian suggested, removing the colors escaped sequences from the source may be simplier. For grep, just append \ : cmd | \grep pattern > file

Re: tab order

Here is what i'm using

function! MoveCurrentTab(value)
if a:value == 0
return
endif
let move = a:value - 1
let move_to = tabpagenr() + move
if move_to < 0
let move_to = 0
endif
exe 'tabmove '.move_to
endfunction

map <silent> <A-S-j> :call MoveCurrentTab(-1)<Esc>
map <silent> <A-S-k> :call MoveCurrentTab(1)<Esc>
