IIRC it came up in the recent feature poll.

That said, you can send commands from one GVIM instance to another instance -- 
e.g. make it open a file etc. Before vim's new async features, some plugins 
used this for background tasks.

Re: GVIM: alt/meta keys: inconsistent results for getchar(0)

Additional question: When I press  only once, I get one 
'<80>^H<80>ku' and 9 '<80>^H' although no key is pressed at that time.

This can also be done with:

echo getchar()|for i in range(10) | echo string(getchar(0)) | sleep 50m | 
endfor

Is that expected? In this situation, I'd naivly expect the first getchar() to 
return '<80>^H<80>ku', and the subsequent getchar(0) to return 0.

GVIM: alt/meta keys: inconsistent results for getchar(0)

[lith]

Hi!

When I run this code in Windows GVIM and press, e.g.,  in a row:

sleep 1|for i in range(10) | echo string(getchar(0)) | sleep 50m | endfor

I get a mix of '<80>^H<80>ku' and '<80>^H'.

When I increase the timeout to 150m, I get only '<80>^H<80>ku', which seems 
correct.

Is this expected? Is it a bug? Is there another way to make sure I get the 
right key code other that using sleep?

Tom

Re: Feature/plugin dependency checks in plugins

Many plugins define a variable that holds the plugin version

in plugin/FOO.vim.

Do you really have to check for that dependency in the file under the plugin 
directory? IMHO it's often sufficient to check dependencies in an autoload file 
which also solves this problem.

vrapper is quite ok actually. It also supports creating maps etc. I think it's

the better tool for the problem at hand, you're probably better of with just 
using eclispe the way it is plus a light vim-mode plugin.

BufReadPre event vs file that isn't readable for now: How to mount a volume before reading the file?

[lith]

Hi!

Let's say, I want to edit a file that is on a volume that is not mounted yet. 
From the perspective of vim, the file doesn't exist. Whenever I want to edit 
that file, I have to mount that volume first.

The docs on the BufReadPre event say:

BufReadPre  When starting to edit a new buffer, before
reading the file into the buffer.  Not used
if the file doesn't exist.

So, I cannot use this event to prepare reading a file that is temporarily 
unavailable, e.g., because its volume isn't mounted yet.

Is there another event that I can use to mount the volume before reading the 
file.

Tom

Re: standard way include plugin as a dependency of another plugin

I sometimes use something like this:

runtime plugin/DEPENDENCY.vim
if !exists('g:loaded_DEPENDENCY') || g:loaded_DEPENDENCY < 100
echoerr 'DEPENDENCY >= 1.00 is required'
finish
endif
endif

This makes sure plugin/DEPENDENCY.vim is loaded. The file has to be in the 
runtimepath. This solution is suboptimal if g:loaded_DEPENDENCY < 100 though.

Not the original author but I ran into similar problems with optional plugins

Re: Fixate window layout?

> > Try 'winfixheight' and 'winfixwidth'.

> And 'winpos' for position.


Maybe I didn't make myself clear. With "window" I refer to windows in vim,
not the frame of the gui window.

When I execute the following:

e foo
vsplit bar
windo setl winfixheight winfixwidth

I end up with a tabpage with two vertically split windows.

The commands `wincmd c`, `bdelete` will remove the split and I end up with
a single vim window. Neither winfixheight nor winfixwidth protected me from
this. But I'd rather expect/want the other window to not change at all and
the current window be displaying a new empty buffer -- or the previous
buffer if any.

I know that there are some vim tips (i personally use vimtip 1078) & code
snippets around that can replace `wincmd c` or `bdelete` and won't change
the layout but this doesn't keep plugins from changing the layout.

Fixate window layout?

[lith]

Hi!

When switching back from eclipse to vim, I sometimes find it (still) surprising 
that vim doesn't seem to provide a way to "fixate" the window layout. While I 
think the volatility of the window layout is an advantage when working on a 
small screen, it can be annoying on a big screen, where I would prefer certain 
windows to never change their size or position.

What are currently the best options to make certain windows stay put regardless 
of how the other windows on the tab page change? Does Vim8 add anything new in 
this respect?

Reschedule a timer?

[lith]

Hi!

Is there a way to reschedule/delay a timer. Something like:

let t = timer_start(1000, 'DoSomething')

Then after, say, 500ms:

call timer_reschedule(1000)

Then wait another 1000ms for DoSomething to be called.

I could of course stop the old and start a new timer but I guess this would 
waste  resources and be quite inefficient if being done very often.

An alternative approach would be to use the CursorMoved(I) events to toggle the 
readonly option depending on which line the cursor is located at.

E.g. the setsyntax plugin 
(http://www.vim.org/scripts/script.php?script_id=2076) can be used to achieve 
something like this based on the syntax group under the cursor.

The problem with these oneliners is that values can be empty strings (keys must

How to determine whether an option is boolean?

[lith]

Hi!

Some vim options are boolean, i.e. integers with the possible values 0 and 1. 
You can, e.g., set `ai` and `noai` or use `let ai = 1`. Other options are 
numeric/integer or string values.

type(option) can only be used to distinguish string from bool/int options. 
exist('noai') returns 0, so it cannot be used to distinguish bool from int 
options. Is there another way to determine whether an option is a bool (an int 
that takes only the values 0 or 1) or an int?

Best way to programmatically define a function

[lith]

Hi!

What's the best way to create a function that creates functions?

I currently construct a string with the vim code, put that into a register, and 
then evaluate the register. See 
https://github.com/tomtom/tcomment_vim/blob/master/plugin/tcomment.vim#L165 for 
an example.

This works well but seems to cause serious problems in certain situations with 
certain installations. See here for an example report: 
https://github.com/tomtom/tcomment_vim/issues/140

Is this a known issue with certain versions of gvim?

Is there an alternative way to achieve this that doesn't cause the problem 
reported above?

Re: shorten the display of url's while note taking

[lith]

 You could use the conceal feature to hide parts of the text. Then by 
 default when you move the cursor onto the line, the hidden text would be 
 shown. Or you could set it up so that only happens in visual mode, or insert 
 mode.

I use this for a similar purpose in the viki plugin. Unfortunately, it doesn't 
play well with word wrap which is why text with shortened URLs tends to look 
awkward.

An alternative solution is link maps, i.e. use a shortcut in the text and 
have the URL for that shortcut defined in a specially formatted 
table/definition list someplace else -- similar to footnotes.

Re: Automatic completion from word list

[lith]

 likelycomplete seems to think that  is not a real file type,
 which is unfortunate as it's what I'm in half the time.

If you're writing prose, I'd suggest to set ft to text or something similar. 
(Or use markdown markup.)

 The parameters are all global but my language and abbreviations
 settings are per window which makes interfacing the two
 difficult.

It's possible to override filetype by setting b:likelycomplete_filetype. I 
guess I could add w:likelycomplete_filetype (a window specific variable), which 
would help solving your problem.

 Fuzzy matching has a perceptible delay, even with a small
 dictionary (13_000 words, 100 kB)

That's possible. :-) I should probably add a quick ranking mode. By default, 
likelycomplete remembers the words you write most frequently.

I guess adding

  let g:likelycomplete#match_beginning = 1

should improve the situation. By default it also takes into account 
middle-of-word matches.

I think we should continue the situation off list. If you want you could also 
file issues at https://github.com/tomtom/likelycomplete_vim/issues

Tom

Re: Poll: What's good about plugin managers?

[lith]

 Is it fine to have a choice of plugin managers, or is this causing a
 headache (for users and/or for plugin writers).  If yes, then we should
 pick one plugin manager and retire the others.

I'm glad you picked this topic up.

I personally use simple shell scripts to keep the git repos up to date. I don't 
think having the plugin manager built-in is a necessity although it would make 
things easier for newcomers, I guess.

IMHO almost any choice is better than the current situation.

Re: Automatic completion from word list

[lith]

 Is there any particular reason why
 https://github.com/tomtom/vimtlib/blob/master/INSTALL.TXT
 suggests installing as a Pathogen bundle

This page is linked from the github repo. The install instructions are meant 
for users who want to use the github repo. The repo is for people who want to 
use the version I use.

 https://github.com/tomtom/likelycomplete_vim/blob/master/doc/likelycomplete.txt
 only talks about vimballs (of which I see none under
 https://github.com/tomtom/likelycomplete_vim/) ?

The (rarely updated) vimball is on vim.org[1]. Install instructions in the help 
file are the same I use for vim.org.

I personally install vim plugins from their source code repo if one is 
available.

 This may be a trivial question to those in the know but I'm
 confused by the zoo of installation methods for Vim add-ons /
 plug-ins / scripts / whatever they're called. At this moment,
 freedom from choice is what I want. g

The problem here is that the vim ecosystem has significantly changed during 
the past years with the advent of, e.g., github and plugin managers that know 
how to deal with git repos and the like. Unfortunately, VIM doesn't have such a 
full-fledged plugin manager built-in what causes this confusion. (There is GLVS 
but that's from a different era when plugins were still distributed as zip 
files.)

Anyway, I admit this could be confusing. I'll revise my install instructions. 
Thanks for your feedback.

@all:
Does somebody know a comprehensive vim plugin installation guide that covers 
vimballs, zip files, addon managers etc.?

Re: Automatic completion from word list

[lith]

 E.G. I type atmcy then space or punctuation and
 automatically is inserted because that's the match for
 /^a.*t.*m.*c.*y/ in the word list.

I'm currently working on a plugin[1] that can be configured to fit your example 
to some extent:

let g:likelycomplete#select_imap = 'c-s-space'
let g:likelycomplete#use_fuzzy_matches = 1
let g:likelycomplete_filetypes = [your filetype]
let g:likelycomplete#other_sources = ['g:my_words']
let g:my_words = ['automatically']

This allows you to type

atmcy

On c-s-space users will be presented a list of possible completions, 
including automatically. (There is also an option to use c-xc-u but 
that's less useful for long lists.)

It's not the typical use case of that plugin though. :-)

 On the contrary. vim-wikia was started specifically BECAUSE the original

Let's not forget (IIRC :): When the spam tips started, you could post tips

Re: Link to vimweekly.... possible replacement for vimwikia

[lith]

 The goal here is very simple, - I will serve as the maintainer of the project 
 and will be responsible for all the edits. The tips on VimWeekly will heavily 
 based on community input, stackoverflow, books and the ultimate vim manual. 

I think it would be a good idea to collect the tips in a way that makes them 
accessible through vim help. There are scripts that convert vimwikia tip pages 
to vim help format. I think your newsletter should provide similar 
functionality -- e.g. by making them also accessible via github in plain text 
format that could later on be converted to vim help files.

I personally think a weekly newsletter is a good format to fight information 
overload and to distribute news/tips to the community.

improving Vim - Kickstarter - brainstorming - goals - who wants to join?

[lith]

There definitely always is some space for improvements. I'd nevertheless like 
to ask if you really think that more of the same is a significant improvement. 
Vim is a versatile editor the way it is. I still wish it would have emacs-like 
overlays and maybe js as scripting languagee, since I'm convinced js will gain 
more dominant in the years to come but it really doesn't matter that much.

Rather than a slightly improved version of vim, I'd like to see a free version 
of vim for eclipse that is able to run any vim plugin and fully integrates with 
eclipse (though eclim already is great) and/or a browser/web based version of 
vim that runs any vim plugin and that works with the local file system or files 
on some server.

Do you have any plugins installed? I don't know the lua ftplugin but maybe (if

Re: How plugin writers write help document?

[lith]

 But some of them don't have Vim style document.
 I am wondering is there any support tool for write vim document.
 Or is there any good practice while writing Vim style document.

It's not necessarily good practice but I wrote a ruby script[1] that takes a 
template file (which usually contains some sort of Getting started section) 
and a file list and then extracts comments from a plugin's vim source files and 
creates a help file for you. IMHO it's easier to keep the help file up to date 
this way.

Re: Script to send selected text from Vim to R in Ubuntu

 a script that takes a selection in Vim and sends it to R

You should probably run R via screen/tmux and then use a vim plugin for 
screen/tmux to send the code to R. You could either use a generic plugin or, 
e.g., rcom[1] (which can use screen.vim or its own functions) for that purpose.

Since your question is specifically about R, you might also want to check the

more complex solution for your problem.

 let's you choose which plugins to activate easily.

Alternatively, you could use the tplugin script 
(http://www.vim.org/scripts/script.php?script_id=2917), which will define proxy 
commands  catch calls to undefined functions (similar to the AsNeeded plugin) 
in order to enable plugins only when they are needed. You have to run the

Partial support for todo.txt syntax is also implemented.

It can be configured to display (over)due tasks when starting vim. Other than

Re: special keymap depending on language

 So my question is rather simple: can I load this file only when editing

I once created the linglang plugin to handle mixed-language texts 
(http://www.vim.org/scripts/script.php?script_id=2292) but haven't used it much 
since. You'd have to create a file with words that are likely to occur in 
French text.

For French, I think it would be sufficient to search for vowels with accents to 
determine whether it's English or German. There is no way to decide on the 
language of an empty buffer though. :-)

I made good experiences with determining a text's language using compression 
algorithms (i.e. zip). It's rather easy to implement and relies on different 
compression factors of text written in different languages. I can point you to 
an implementation in ruby if you're interested.

Re: Plugin manager with dependencies and selective bundle load

[lith]

Hi,

 I love how fast vim loads using tplugin and how it changes the runtime path 
 on demand.
 But then I also found some limitations. Seems thare is no way to tell the 
 tool not to load some plugins, also the dependency system looks a little but 
 clunky because it is based on files rather than bundles.

I'm not sure what you mean by not loading plugins. Since version 0.14, you 
can define shallow root directories. Plugins in such a directory can be 
loaded by means of the :TPlugin command but shouldn't be automatically loaded 
if you call one if its commands or functions etc.

Dependency handling can admittedly be improved. tplugin knows three ways of 
handling dependencies:

(1) Don't handle dependencies and load plugins as needed (this won't work if a 
plugin tests if another plugin was already loaded by checking the existence of 
a variable)

(2) Check if a plugins checks for the existence of loaded_PLUGIN_NAME (this 
requires that the plugin authors adhered to the formatting rules which they 
probably didn't :-)

(3) Use the info in *-addon-info.txt files if the plugin provides one.

If the above fails, you can define a file _tplugin_PLUGIN_NAME.vim to define 
dependencies like:
call TPluginDependencies('THIS_PLUGIN', ['OTHER_PLUGIN'])

I guess you could put this definitions also into vimrc.

Re: tracking text

[lith]

  Basically i am trying to track all the new text 
  i'm adding to a file. 

 Great! By the way, I searched the vim.org scripts for signs and came 
 up with a few plugins that might already do what you're looking for


In case the files are under a vcs (git, svn, hg), I'd like to add 
quickfixsigns (http://www.vim.org/scripts/script.php?script_id=2584) to the 
list.

The OP could also be interested in the SaveSigns plugin (
http://www.vim.org/scripts/script.php?script_id=2992) that lets users save 
signs.

balloneval: balloonexpr over empty lines

[lith]

Hi,

I noticed that bexpr doesn't seem to get called when the mouse pointer 
hovers over an empty line. This can be easily be tested with:

vimrc:
set nocp
set beval
set bexpr=MyBalloonExpr()
function! MyBalloonExpr()
return 'Cursor is at line ' . v:beval_lnum .
\', column ' . v:beval_col .
\ ' of file ' .  bufname(v:beval_bufnr) .
\ ' on word ' . v:beval_text . ''
endf

$ gvim -u vimrc

Is there a way to change this behaviour and to make vim display balloons 
over empty lines?

Tom

The quickfixsigns plugin uses balloons to display additional information 
about a sign when the mouse pointer hovers over a sign. This is especially 
useful, e.g., when displaying git diff information. Unfortunately this 
doesn't work when the line is empty -- e.g. when you replaced text with an 
empty line.

Would it be possible to change the test to (len == 0  no_sign_at_line)?

You can convert the file at the FileReadCmd event to text (or to html and

Re: rating manipulations on www.vim.org have taken place

 If throwing out old votes seems too drastic, maybe the votes
 could be displayed according to their age, with totals computed
 over the past 6 months, 1 year, or the entire history.

I didn't follow this thread to closely but IIRC some of those ratings could 
stem from clicks on search pages. For the period of time, GET was used (see 
another posting in this thread), some links in google results pointed to a 
link that would send a rating but not to the actual plugin page. A user 
most probably didn't even notice the difference -- I thus wouldn't 
necessarily assume abuse.

I wouldn't consider removing old ratings (or yearly cutting them down to 
50%) a problem. It would rather help to weed out outdated scripts.

Re: Backporting script to vim 6.3 (need help)

[lith]

 So then I guess I won't be able to return mulitple arguments. I need
 to do some rewriting then... hmmm

In vim6 there are only two types available: string and numbers.

You can use strings to emulate arrays (there is a quite usable library for 
that but I forgot its name ... genutils maybe? ... not multvals it was). 
For dictionaries, you could use array whose values match specific patterns 
... somehow. :-)

An alternative approach is to pass around strings that define local 
variables when being executed. E.g.

function! Foo(a)
return let val1='foo. escape(a:a, ') .'|let val2 ='bar. 
escape(a:a, ') .'
endf

function! Bar(a)
exec Foo(a:a)
echo Bar a:a is val1 and val2
endf

call Bar(lala)

You might want to reconsider updating vim. :-)

There are a few plugins around (e.g. my own ttoc) that display an overview

to the example in :h definition-search, you could also use the following

i.e. the let command is executed on every item.

 We could move all existing plugins on www.vim.org (which don't have any

Isn't this self-contradictory? A plugin with no maintainer will probably 
never be updated. Why maintain it in a DVCS then? If somebody wants to 
create a fork, he/she is free to maintain the fork on github/bitbucket/etc.

BTW I wouldn't make vim.org too dependent on github. Different people prefer 
different VCS or hosts. Maybe the plugin form could contain an URL field 
that is used to retrieve the README, wherever it is hosted. I'd display the 
README as plain text only.

I personally think tags would be a great step forward.

let s:base=join(s:parts[0:-2],'_')

tskel:after
unlet s:filename s:parts s:class s:base 
/tskel:after
?php class +s:class:C+ extends +s:base:C+ {

If you save it as ~/.vim/skeletons/bits/php/class, this will create a

You can include snippets if that's what you meant.

+bit:other_snippet+
 

 as they imply some complexity if we want to support things like a 
 switch-snippet that loads the case-snippet for every value from an

I haven't tried something like this before but you should be able to do:

+for(s:var in s:parts)+

where other_snippet is:

 but that requires a lot of context pushespops

Every snippet is expanded in a scratch buffer of its own.

I think it's a matter of how much of your work you will be doing with vim. 
Learning the vi(m) style to work with plain text pays off if you do most of 
your text editing tasks in vim. If you still use word processors and other 
text editors a lot, I personally wouldn't consider vim a good choice.

There is also the question how you get text edited with vim into some format 
you can submit. vim isn't particularly good at editing text with no hard 
line breaks (tw=0), i.e. soft wrap. In order to get some text formatting 
into e.g. Word, most likely requires the use of some command line tool that 
converts the text to something Word can read. I'm not sure such tools are 
easy to use for somebody who has never written a single line of code.

remote_send() to open it in the other instance. E.g.,

! start gvim --server-name Foo
let fname = fnameescape(expand('%:p'))
bd!
call echo remote_send(Foo, :e . fname .\cr)

I'd also make sure they know how to search for vim plugins and
information on the vim wiki. The use of vim plugins would IMHO require
a basic understanding of the layout of the vimfiles directory. So one
task could be to install a plugin and to customize a certain option by
setting a variable in vimrc or in after/plugin/whatever.vim --
depending on what is appropriate.
