I recently abandoned snippet plugins for leader mappings and now wonder how I ever justified entire plugins in the first place. In my case, after/ftplugin/c.vim, for example, has a total of eight mappings and two abbreviations. I do not feel short-changed.

Are you talking about terminal and / or GUI?

It sounds like you're talking about GUI and wanting the vim window to
widen to accommodate the new split.

Someone already suggested the statusline option.

If you only have one window open, by default no status line (where the other information is usually shown) is displayed. The 'laststatus' option controls this, set it to 2 to always display it.

Re: vim74 cannot see selected line number in ubuntu desktop

I have something similar which shows as a construct of my statusline.

help statusline

especially the values vV c lL P

The relevant part of mine includes:

col:%c%V\ lin:%l\/%L\ %P

which shows like this:   col:5 lin:10/20 50%

meaning column 5, line 10 of 20, 50% file lines.

Splits and resizing

I almost always do a vertical split to the left of my main window. I would like the main window I started with not to resize when the split is added (widening the window to accommodate the split) and when closing the split I am back to the original window size.

Help?

Try using putting explicitly `:filetype off` into your .vimrc and see if
that helps.

Other than that, you can of course run vim as a vi compatible version
using `vim -u NONE` or running it as `vi` should usually also get you a
close enough approximation of the original vi.

I've seen ".cl" used a few times for PHP classes, but I'm not sure how
common it is outside the place I worked in the 2000s.

Let's try a different approach.

Is there something I can set that tells vim "forget 'improved', just
behave like the 4.2bsd version of vi" (or any other "classic" vi).

Not that I'm against the improvements, I'm especially fond of the fact
that when you edit a file you've edited before, it starts at the current
line from the last time, even if a long time ago. I also like the fact
that vim will detect if you previously edited this file and the session
ended without closing the vi (e.g., power failure or system crash) and
gives you options to "restore" "edit anyway" "read only" etc.

But if I can just use it as a simple text editor without getting lost in
its guesses about my file type, I'm willing to give that up and just use
it like plain old vi that I've used since 1976.

Re: Controlling the display of a syntax highlighting group

One more addendum:

In the external file, I changed the line:

highlight NONASCII ctermbg=13

to:

highlight NONASCII ctermbg=13 guibg=Magenta

so that the command would work in gvim as well as vim.

Re: Controlling the display of a syntax highlighting group

I previously asked how I could set up a toggle for syntax highlighting

of non-ASCII characters. I was having problems clearing a

highlighting group and then never being able to reactivate it.

Ben Fritz suggested using the matchadd()/matchdelete() functions

for the job. That looks like a good idea and would probably be cleaner

than what I did, but I solved the problem another way before seeing his comments.

Tony Mechelynck suggested using some functions (see above).

I tried these and they exhibit the same problem I was finding: they

work exactly once and then not again. There is some strange

interaction happening with the highlight group that I have not yet been able to identify.

I did manage to resolve the problem and integrate it into other syntax highlighting with some work. Here is my solution.

First, I assigned a command to the L9 key that would toggle basic

syntax highlighting on/off:

" L9 Key                                       [Toggle syntax hilight on/off]
nnoremap <Esc>[55~ :if exists("g:syntax_on") <Bar>
                     \     syntax off <Bar>
                   \     endif <Bar>
                   \ else <Bar>
                   \     syntax enable <Bar>
                   \ endif<CR><CR>

Next, I assigned the shifted L9 key a command to toggle non-ASCII highlighting on/off. The trick here was to clear the syntax but NOT

the highlighting group.

" L9 (Shifted) [Toggle nonascii highlighting]
nnoremap <Esc>[55;2~ :source /u/jeff/lib/vi/vimrc.nonascii<CR>

Where the vimrc.nonascii file contains:

if (nonascii == "on")
    syntax clear NONASCII
    let nonascii = "off"
else
    syntax match NONASCII "[^\x00-\x7F]"
    highlight NONASCII ctermbg=13
    let nonascii = "on"
endif

Now you ask, why is this in an external file rather than directly

mapped as in the previous case. Well, I tried that and found that

while it sort of worked, not only did all non-ASCII characters get

highlighted, but so did all white space (space and tabs) between

them! This does not happen when the command is read from the

external file. [I'd be happy to hear any ideas as to why that is

happening and what to do about it!]

OK so far. However, if non-ASCII highlighting was active and syntax

highlighting was toggled, it forced the non-ASCII highlight off too and

left the "nonascii" variable in the wrong state.

I wanted these to operate independently, so I modified the previous

L9 Key mapping as follows, to force non-ASCII highlight back on if

it was currently on.

" L9 Key [Toggle syntax hilight on/off]

nnoremap <Esc>[55~ :if exists("g:syntax_on") <Bar>
                   \     syntax off <Bar>
                   \     if (nonascii == "on") <Bar>
                   \         let nonascii = "off" <Bar>
                   \         :source /u/jeff/lib/vi/vimrc.nonascii <Bar>
                   \     endif <Bar>
                   \ else <Bar>
                   \     syntax enable <Bar>
                   \     if (nonascii == "on") <Bar>
                   \         let nonascii = "off" <Bar>
                   \         :source /u/jeff/lib/vi/vimrc.nonascii <Bar>
                   \     endif <Bar>
                   \ endif<CR><CR>

Why two <CR> are required here is another minor mystery. It's

probably because of the :source command which gobbles one

<CR> leaving the second for the overall command. However,

adding a <CR> to the end of the :source lines and removing one

from the end does not work!

I hope someone finds this instructive. Continue the discussion if

there are more insights as to what is going on with these perceived

glitches I was experiencing.

Much thanks to Ben and Tony for their very helpful feedback. I

learned a few things and got pushed in the right direction.

I can confirm that with the guitermcolors option indeed the only

But you don't want to disable loading plugins altogether, but rather
apply settings to a particular filetype/extension, right?
So you should rather go with those articles:
https://vimhelp.appspot.com/vim_faq.txt.html#faq-26.6
https://vimhelp.appspot.com/vim_faq.txt.html#faq-26.8

Please also check the links to the documentation in Vim.

according to $VIMRUNTIME/filetype.vim .cl extensions seems to suggest
common lisp files. So Vim sets the lisp filetype.

Does the ".cl" extension have any special meaning to vim?

What does vim think an extension of ".cl" means?

I've been writing a program that will take a list of input HTML files (some written using an editor like vim, some generated by MS Word) and convert them to legal (and reasonably clean) XHTML. The program is written in PHP, and I've been following the convention of putting each class in a separate file. So I have one top-level file (an "executable" using the #! convention), a few "include" files with the extension ".inc", and my classes in files with the extension ".cl".

But when I try editing the .cl files with vim, auto-formatting doesn't work. I have autoindent set, but every new line starts in column 1, regardless of the indention of the previous line. Also linewrapping doesn't work (set fo+=tcroqj)

I had various ideas of what was wrong, and I think I have eliminated all the others. But as far as I can see, vim does what I expect *unless* the extension is ".cl". In a file named *.cl, autoformatting just doesn't work. Period.

What's up with the .cl extension? Is there a way to get .vim to treat it like .php? Or should I just live with it and change my naming convention to match whatever assumptions are built into .vim?

Btw, this occurs in the vim that is downloaded with cygwin
VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Jan 27 2017 13:34:58)

and also when I right click on a file and choose "Edit with Vim".

Here is my .vimrc file, FWIW:
~ % cat .vimrc
set autoindent
set nohls
syntax off
set tw=72
set ws
set ic
set ts=8
set sw=4
map :n

I suggest using the matchadd()/matchdelete() functions for this purpose, unless there is a specific reason you need to use syntax matching. Those are more "temporary" and easy to toggle.

Try the following (untested):

function ASCII_on()
syn match NonAscii "[^\x00-\x7F]"
hi clear NonAscii
hi NonAscii term=reverse ctermbg=Magenta guibg=Magenta
endfunction
function ASCII_off()
syn clear NonAscii

call ASCII_on()

endfunction

I think that vim@vim.org is still acceptable, but I'm not sure: it
used to be a robot on a computer somewhere in an out-of-the-way place
in the Math faculty of some German university (Uni-Erlangen IIRC), and
no one knew anymore how to fix anything that went wrong with it. IMHO
the Google Group is more reliable.

Controlling the display of a syntax highlighting group

To find non-ascii characters in a file, I have defined the following:

syntax match nonascii "[^\x00-\x7F]"

highlight nonascii ctermbg=13

I can disable this with the command:

syntax off

I would like to create a command that toggles this highlight group on/off and

hopefully do so without affecting the current state of the remainder of the

syntax highlight groups. I have not found a way to test the state of this

group, and once activated, I cannot seem to clear or edit the highlight

definition non-destructively.

Any pointers?

[P.S.: I originally sent this to <vim@vim.org> which is the address listed
on the official Vim mailing list page, but it never showed up. Is that still

How to copy/paste in terminal on Windows

Hi forum,

I'm using gvim on Windows, checking the new :terminal feature.
How can I copy/paste text inside the terminal window? The usual DOS way of marking with the mouse and right-clicking does not seem to work. The only way I found is going to Terminal-Normal mode with CTRL-W N , yanking the text with vim commands, returning to Terminal-Job mode and pasting with CTRL-W "". Is there a better, easier, way?

Thanks,
-- Massimo

But ^[ means Escape, not Tab,
and Escape, when used in a mapping, works like Enter (usually):
:h c_Esc

So you want <Tab> (right?) which looks more like ^I, but anyway in a mapping you can't use <Tab>,
instead you need to use the key defined with
:h 'wildcharm
(:set wcm=<C-_> works for me).

Your mapping becomes (with above 'wcm' setting):
:nnoremap \\ yiw:h <C-R>"<C-_>

or
:nnoremap \\ :<C-U>h <C-R><C-W><C-_>

or (I think I'd use)
:nnoremap <Leader><Tab> :<C-U>h <C-R><C-W><C-_>

Vim 7.4 is already somewhat out-of-date. Vim 8.0 was released on
12-Sep-2016, and since then it has seen more than a thousand
enhancements and bugfixes. Have you tried it?

I am on Linux64, and I've never had the case of HTML files opening in
readonly mode, except of course when using "view", or when the file
either had the readonly attribute, or was on a readonly medium such as
a CD-ROM.

Have you got "user" or "sysadmin" customizations, setting readonly
when an HTML file is opened? Try the following:

1. Start Vim or gvim (not view or gview) with an HTML file located on
your hard disk, and neither in a readonly directory nor with the
readonly attribute set on the file itself.
2. That file being the current editfile, type

:verbose setlocal readonly? modifiable?

followed by <Enter>. The answer should tell you not only how these two
options are set on the file, but where they were set. The question
marks are important here, because without them you would be setting
these Boolean options to TRUE rather than asking how they are
currently set.

Tony.

Evoking the option for :help in a mapping

I have the customary mappings for :help,

nmap <F1> :exec "help " . expand("<cword>")<CR>
nmap <S-F1> :exec "help " . expand("<cWORD>")<CR>

and have been trying to develop similar do the <Tab> option on the cursor word, something like

nmap \\ yiw:h ^R"^[

but to no avail. Although the mapping does not terminate with a <CR>, vim treats the ^[ as if it were <CR> rather than <Tab> and goes straight to the specific help for the cursor-word.

Is it possible to have vim act on the <Tab> as it does in the command line?

Color 7 is supposed to be grey, but color 15 is supposed to be white.
You can try this with:
:hi Normal ctermbg=15

Has nothing to do with the terminal feature. This is with t_Co set to

In many of the more relaxed civilizations on the Outer Eastern Rim of the
Galaxy, "The Hitchhiker's Guide to the Galaxy" has already supplanted the
great "Encyclopedia Galactica" as the standard repository of all knowledge
and wisdom, for though it has many omissions and contains much that is
apocryphal, or at least wildly inaccurate, it scores over the older, more
pedestrian work in two important respects.
First, it is slightly cheaper; and second, it has the words "DON'T PANIC"
inscribed in large friendly letters on its cover.

Problem with :argdo and :vimgrep on latest Windows build

I'm using VIM 8.0.586 on Windows 10. Recently, I've experienced strange and unexpected behavior when using ":argdo" and ":vimgrep".

When I use either of these commands, the text being operated on or searched seems to "fly by" on the screen. This is almost as if VIM is playing out the operations for me as the text is scanned. This is certainly new behavior.

I checked and made sure that "lazyredraw" was set. What could be the issue?

I am on Linux though. And I can set background background through bash or
zsh escape sequences but that's not very reliable. When using ls or man
it will break in one way or the other (ls will often show patches of the
original background color, man will just use the default terminal
background color). When running an xterm I just use the `-bg` flag
which works perfectly fine (or just set up things in .Xresources file).
Is there a such a way with libvterm?

I see very similar behaviour that Lifepillar has. The background is
white or black rather than what is in `:hi Normal`.

Best regards,
Marcin

In both Terminal.app and iTerm2 with notermguicolors, the terminal
background is set to Vim's background, as you say. Not all of the 256
colors look right, though. Attached you find a screenshot: the
colorscheme is Solarized 8, although the particular colorscheme should
not matter. See how a few of the 256 colors are out of place, and also
a shade of gray is wrong. Of the system colors, Normal White (color 7)
and Bright Black (color 8) are grey instead of Solarized white
(#EEE8D5) and Solarized black (#333344), respectively. Note that this
is what I see also in iTerm2, so this does not appear to be
a terminal-specific problem (or, both terminals have the same issue).

In iTerm2 with termguicolors, the terminal does not seem to inherit
the colorscheme's colors, but it appears to always use default colors
(the 256 color palette looks right in this case). In particular, the
background is always white or black, depending on the value of
'background' at the moment the terminal is started. See the other two
attachments. This is also what I see in MacVim.

Finally, I have tried NeoVim's terminal for comparison, and colors
appear to look right under all circumstances. So, it is definitely not
"impossible" to correctly set all the 16 system colors (but, maybe,
NeoVim is doing something hackish?).

Your php files have probably special settings in the corresponding
filetype plugins. And possibly, if you enabled indent plugins, there
exists special logic there as well. If you want to have your .cl files
be handled like php files, check e.g. the faq:
https://vimhelp.appspot.com/vim_faq.txt.html#faq-26
(there are several questions in the 26 block, that might be of interest
to you). And follow the links to the documentation in Vim.

Also, if .cl is kind of a official extensions for Vim, we might need to
extend our logic to detect php like files.

Best,
Christian

.cl file type?

What does vim think an extension of ".cl" means?

I've been writing a program that will take a list of input HTML files
(some written using an editor like vim, some generated by MS Word) and
convert them to legal (and reasonably clean) XHTML. The program is
written in PHP, and I've been following the convention of putting each
class in a separate file. So I have one top-level file (an "executable"
using the #! convention), a few "include" files with the extension
".inc", and my classes in files with the extension ".cl".

But when I try editing the .cl files with vim, auto-formatting doesn't
work. I have autoindent set, but every new line starts in column 1,
regardless of the indention of the previous line. Also linewrapping
doesn't work (set fo+=tcroqj)

I had various ideas of what was wrong, and I think I have eliminated all
the others. But as far as I can see, vim does what I expect *unless* the
extension is ".cl". In a file named *.cl, autoformatting just doesn't
work. Period.

What's up with the .cl extension? Is there a way to get .vim to treat it
like .php? Or should I just live with it and change my naming convention
to match whatever assumptions are built into .vim?

Btw, this occurs in the vim that is downloaded with cygwin
VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Jan 27 2017 13:34:58)

and also when I right click on a file and choose "Edit with Vim".

Here is my .vimrc file, FWIW:
~ % cat .vimrc
set autoindent
set nohls
syntax off
set tw=72
set ws
set ic
set ts=8
set sw=4
map :n
map :w

The program you run in the terminal can change the background.
Otherwise the same background as Vim is used.

Note that on Mac it appears to be impossible to set the background color
to white. That's a problem with Terminal.app.

You can use something like this

iabbrev <expr> class getline('.') ==# 'class' ? 'class (object):' : 'class'

The key moment here is "<expr>". The expression

getline('.') ==# 'class' ? 'class (object):' : 'class'

will be evaluated to obtain replacement string. You can make it more
accurate by comparison only with the part before the cursor position.

Can I write an abbreviation that only works at the beginning of the line?

Hi,

I am asking here because I am not sure myself how to google it.
I tried with something similar to the subject of this email, but no
luck. That, or I didn't actually understand what I found.

Let's say, and this is not my real need but a very clear example, I
want to write an abbreviation that converts, when writing python code:

class

into

class (object):

But I only want that to works when string "class" is being printed at
the beginning of a line.
I don't want the replacement to happen when I am writing the docstring
like "This is a class that does this and that".

Is it possible?

Controlling the display of a syntax highlighting group

To find non-ascii characters in a file, I have defined the following:

syntax match nonascii "[^\x00-\x7F]"

highlight nonascii ctermbg=13

I can disable this with the command:

syntax off

I would like to create a command that toggles this highlight group on/off and

hopefully do so without affecting the current state of the remainder of the

syntax highlight groups. I have not found a way to test the state of this

group, and once activated, I cannot seem to clear or edit the highlight

definition non-destructively.

Any pointers?

Thanks,

If you want to use a built-in feature, you may use abbreviations (`:help
abbreviations`). In the simplest form:

iab <buffer> if if () {<cr>}<c-o>2gE

You may want to put this in ~/.vim/after/ftplugin/perl.vim to make it
filetype-specific.

The above also inserts the space you type after `if`. You most likely
won't wanto that. You may type if<c-]> to expand the snippet without
inserting a space, or use the `Eatchar()` function described in Vim's
help.

If the cases in which you do *not* want `if` to be expanded, you may
type if<c-v><spc> to insert a literal space. Alternatively, give the
snippet a different name, like `if…` (… is <alt>-. in my keyboard).

Enjoy,
Life.
