This seems like a Window Manager / Desktop Environment issue more than

Though I would naively assume that a common NFS mounted home directory

What happens if you run gVim on each machine displaying on the other

IMHO there's no but about it.


A problem is that if somebody comes out with a new Whizbang terminal
that does everything an Xterm does but so much more, and they set
TERM=whizbang, then everyone with scripts and configurations looking
for TERM=xterm* complains that their tools don't work anymore.


I believe that these terminals should default to whizbang or whatever 
their name is.


They can optionally support xterm personality / emulation.

As far as they're concerned, it looks like an Xterm so they want it 
to identify itself as an Xterm.  The same goes for terminals that work 
mostly but not quite like an Xterm but have some "better" features.


I think that the more people that pile onto the Xterm terminal type the 
muddier the water will get.


This seems reminiscent of the User-Agent header for web browsers.

IMHO we should /own/ the terminal type that we are using.  Either create 
a new whizbang terminal and give it an xterm personality / emulation 
capability -or- stick with venerable xterm / vt100 and not expect more 
than the specifications define.



HP had this problem about 40 years ago when they introduced
a successor to the 2645 terminal.  Its ID string was something like
"HP2647" and customers raised Cain that their systems did work right
with the new terminal, so HP changed it to report itself as an
"HP2645".


IMHO HP made the wrong choice.  It sounds like they bowed to marketing 
pressure and made their new HP2647 terminal lie and say that it was an 
HP2645.  Maybe the marketing / support types have more clout than the 
technical types.


I recently copied an xterm definition so that it could be used for 
xterm-color because that's what my terminal reported as and the 20 year 
old system I was connecting to didn't know what xterm-color was.



You can't win either way.


Either you can own the terminal type and do your best / the work to keep 
it pure.  Or you can have a completely unrelated web web browser lie and 
say that it's a 20 year old piece of software that's long since dead, a 
la. User-Agent headers.


If we're going to ignore what the value actually means, then we might as 
well make it a random opaque token.


I don't know what the right answer is.  Some HP products tried to 
use capability strings instead of product IDs with limited success.


My vote is to actually use the value for what it's meant to be and 
actively /own/ the maintenance.



That would help a lot.  Is that what Vim refers to as the
termresponse?


I don't know.


I use that when it matters what the terminal really is.


I often find that the answer back is unset / null or that the terminal 
(emulator) completely fails / ignores it.

The terminal that I use to run ssh does not support it.


Hum.

This sounds like a potential problem in the terminal.  Specifically that 
the terminal should set TERM to the terminal that it's actually emulating.


I consider it a bug if a terminal emulator claims that it's emulating a 
terminal that's more capable than it actually is.  E.g. claiming XTerm 
when it's really VT100 level capabilities.


I also use answer back for some things like this.  I define the answer 
back on specific systems via the ~/.Xdefaults file.  I usually set the 
answer back to be the host name that the terminal emulator is running on.


So, between the contents of the TERM environment variable and the value 
of the answer back, I can have my servers choose how they configure the 
interactive environment.



I am using the Secure Shell extension for Chrome.


The Secure Shell 0.47 (in a tab) that I have installed for work seems to 
have an option to specify the TERM environment variable via Secure Shell 
(icon) -> Options -> Terminal Settings -> Miscellaneous.  If it doesn't 
actually support xterm-256color (what mine's defaulted to) I'd file a 
bug with them.  If that didn't work, I'd change it to something less 
capable; xterm base, or even vt100.  That way the value of the TERM 
environment variable would be more believable.


I feel like the purpose of the TERM environment variable is slipping 
into obscurity and people are setting it to something they've always 
seen, e.g. xterm, and not realizing that it actually has a specific 
meaning.  Instead they are defaulting and having to re-invent the wheel.



I actually haven't tried recently, they keep improving it.


ACK

I just tried the Secure Shell for the first time in a long time and I 
can't get it to connect to anything.  :-/  I'm not upset b/c I found it 
so inferior and frustrating.  That being said, I'm an Xterm power user 
and expect more than the average person from my terminal emulator.

I would play with the formatprg setting.

:help formatprg


shfmt -l -w script.sh


Based on my read of the help section, it looks like formatprg expects to 
read STDIN and write to STDOUT.  So you might need some sort of wrapper 
to read Vim's STDOUT to a file, shfmt said file, then write said file 
back to Vim's STDIN.


But I suspect that this is eminently doable.

I don't think there is any (good*) way for vim to know that you're using

iTerm2's control.

That seems like a reasonable assumption.  Thank you for clarifying.


Depends on what you mean.  There are multiple regex in play:

- the thing looked for in the g/first/


This first one is what I had in mind when I asked the question.


- the boundary looked for when looking backwards (empty line or BOF)

- the boundary looked for when looking forwards (empty line or EOF)

- the thing looked for in the s// command


This is actually where I was wanting to use the contents of g/first/.  ;-)

Using the :norm method, you don't have the two boundary regexen to 
change the most-recently-used-search, so the regex in the :g can be 
preserved into the :s// command so you don't have to duplicate it.


If I'm understanding you correctly, the following regex could be used:

   :g/aaa/?^$\|\%^?,/^$\|\%$/s::bbb:g

Either way, whatever regex the :s// searches for can capture all (for 
replacement with "&") or subsets (with "\(…\)" for replacements 
with "\1" through "\9"), and then use those captured bits in the 
replacement.


I keep forgetting that & matches the full capture.

Including if you use the :norm method and capture them in the :g 
portion.  Here I look for "G" followed by any number of "C"s followed 
by another "G" and then replace them with a "T" followed by the 
"C"s we captured, followed by another "T":


   :g/G\(C*\)G/norm vip:s//T\1T/g^V^M


This seems like the typical subset mentioned above used in conjunction 
with the "last search pattern" (nomenclature?).

As Sven says, it's ugly.  But it's doable and fairly concise in what 
you're describing:


   Find all the "aaa"
   Starting there, search backwards to the previous blank line or BOF
   From there, search forwards to the next blank line or EOF
   Substitute "aaa" → "bbb" on all the lines of that range


Very interesting.

Thank you for that explanation Tim.


Alternatively, you could hack it with normal mode, something like

   :g/aaa/norm vip:s//bbb^V^M

where ^V^M is a control-V followed by a control-M (which makes this 
nasty to put in a mapping or vimrc).  This works because vim knows 
that a "paragraph" is bounded by empty lines *or* BOF/EOF and does 
the ugly work for us.


ACK

Would it be worth while to include word boundaries \< and \> so that you 
don't accidentally get a sub-string?


:g/aaa/?^$\|\%^?,/^$\|\%$/s:\:bbb:g

Also, is there any way to group the first "aaa" so that it could be

I can't imagine doing this in pretty much any other text editor

Depending on how the GPG agent is configured, if the key is in memory,

Correct.

Regardless, "Host" is only an alias.  Call it whatever you want and 
use it just for vi.


Not quite.  "Host" is how you define a set of entries that are for a 
specific host.  The "targetHost" and "tunnel-host" are the names / aliases.


The example ProxyCommand line is associated with the host entry named 
"targetHost".  Meaning that ssh / scp / sftp to targetHost will use the 
entries under the "Host targetHost" line.

I've already tried to add to my .vimrc

I'm still on vim 7.4 and I'm using a version of openssh older 
than 7.3 (this is why I'm still using ProxyCommand instead of 
ProxyJump). Unfortunately to update my linux-box is not an option in 
the near future.


Any idea?


Yes.

Teach OpenSSH how to get to the host by putting entries in the OpenSSH 
/client/ configuration file; ~/.ssh/config or system wide 
/etc/ssh/ssh_config. E.g.


Host targetHost
ProxyCommand ssh -W %h:%p tunnel-host

Host tunnel-host
# any options you might want here

This teaches any and all OpenSSH clients how to get to targetHost 
without needing to specify additional command line options.  I.e. you 
can run the following command:


   gvim scp://targetHost+path

(G)vim doesn't need to worry about /how/ scp connects.  OpenSSH's scp 
command deals with that transparently.


IMHO the OpenSSH /client/ configuration file opens up a world of 
possibilities.

Aliases can be quite useful.  But they generally only work /in/ /the/ 
/shell/.  If you want to use (something like) an alias /outside/ /of/ 
/the/ /shell/ you quite likely need to use something other than an alias.


Scripts or other executables—that are in the $PATH—are quite good for this.

The 3rd alternative, function, will likely have the same limitations as 
aliases.


As a general rule, if I want to use something outside of the interactive 
shell, I use an executable.  This applies equally as well to things like 
running :!theCommand from within vim to running theCommand remotely via 
ssh to creating desktop shortcuts that search the $PATH.

I would bet another order of magnitude that this is the case if you

what was highlighted is now underlined.


This is the same problem as someone had posted a while ago:

This seems to have the same symptoms to me.

You can probably test vim, if not eliminate it from the scenario, by 
playing with ANSI control codes at a command line and see if the 
symptoms are the same as vim when changing screen (see above).

Using some normal command and repeating j. would be much simpler to

I find that repeating commands gets tedious quite quickly.  Especially 
if you're munging data.  Hence why I like regular expressions like the 
one above, or macros (possibly of the recursive variety).  Why should I 
have to mentally execute the test to see if I need to apply the action 
to the line when I can have the computer do it for me.  I just need to 
tell the computer what to do.


IMHO regular expressions and and macros lend themselves to more 
automation.  It might even be possible to move the regular expression to 
a (s)ed script.

Of course, when it comes to Vim Golf, it would be comparable.

Tdx


Alternatively, have you considered recording/macros?


I use macros quite frequently.  I wouldn't have considered them for this

If I need to do something multiple times and I have a wrote process to

You could just record a set of key strokes using the "q" command and 
recall the sequence whenever you want.


Agreed.  It's just not proper for this use case.  And it doesn't answer 
the question of if there is a different method that is like a backwards dw.

I've got all sorts of things like the following:

up to but not including the last d.  I.e. "Td".


But, "Td" leaves the last f there.

I suppose I could use "Tdx".

I figured that there was a Vim movement that I'm not aware of.

Any other solution that tries to find the first space by working

diW works and multiple dot repetitions get the job done.  But i feel 
like there is a better method.

Re: How can i add the same string to many lines ?

Hello everyone ?


Hi,


I would like to add target="_blank" to all my href in a html file.


Okay.  That seems odd, but you do your own thing.

I would like to say to vim : add this string after the second " symbol 
of each line where is the word href.


Can you provide an example?

I'd be inclined to try a regular expression like the following.

:%s///g

Use a non-greedy wildcard match to find an anchor tag (assuming it 
starts with href) and append the target="_blank" to the end.



For now i just use the dot command to each line.


That's annoying, especially if you have a LOT of anchor tags to change.


Thanks for reading.

Indeed.

Change only second match on a line...

['Grant Taylor' via vim_use]

Is there a way to change only the second (or any specific) instance of a 
pattern on a line?


Sort of like how 's/old/new/' changes the first instance of "old" to 
"new", but for the second (or any specific) instance.


Or does this involve changing the first instance of "old" twice and then 
changing the first instance of the "new" pattern back to the "old" pattern?


Extrapolating the above sequence out to subsequent instances would be 
more and more annoying.


I know that I can build a full RE that will match the first, second, and 
subsequent instances and surrounding text but that seems cumbersome 
compared to a tweak of "s/old/new/".

It sounds like you're talking about GUI and wanting the vim window to

Further, sudoedit (which uses your $EDITOR) is safer than running vim under 
sudo.

At least from a security perspective, sudoedit is safer as many editors, vim 
include, provide a way to escape the editor and launch a shell.

"sudo vim /path/to/file" followed by ":shell" gives you root shell.

"sudoedit /path/to/file" followed by ":shell" gives you a shell as your normal 
user.

Re: A very naive question: any doc (book, web page, ...) to learn step by step how to custom configure vim?

I'd suggest not modifying how Vim behaves / does thing while getting started 
with Vim.

However that does not extend to unconfigured Vim.  I say this because things 
like line numbers (:set number), search highlighting (:set hlsearch), and 
(syntax highlighting (:syntax on) do not modify Vim's behavior, but (I think) 
they do make Vim a bit more friendly.

IMHO there's a subtle but distinct difference.

I have also found some people on Twitter that seem to have some impressive 
VimFu.  Here are some people I recommend, in alphabetical order:

@ed1conf - Vim can do much of what ed does, and ex mode is quite similar.
@gumnos - WONDERFUL resource. Tim is happy to explain the odd things that he 
does in Vim.
@MasteringVim - Lots of good information and is working on a book.
@nixcraft - LOTS of good unix things, including Vim info.
@VimLinks - Frequently has interesting Vim specific things.

I also frequently tweet, as @DrScriptt, things about Vim, or comment on other 
peoples tweets, frequently asking questions.  @gumnos tends to have wonderful 
answers to explain things.

I played, enjoyed, and learned from VIM Adventures 
(https://vim-adventures.com/).  (I never beat the boss at the end.)  - I'm 
tempted to re-up my subscription and play again.  -  There are some free levels.

I would also recommend that you learn some about regular expressions.  -   Vim 
is a little bit different than other RE engines, mainly in escaping some 
special control characters.  -  I find that RE's are EXTREMELY powerful and 
probably what brought me into Vim.

Sorry for devolving from Vim customization into general Vim.  -  But then 
again, you need to learn enough base Vim to decide what you want to customize.

Finally, strive to understand what things do, and how they do it.

@gumnos and I had a discussion about the following yesterday:

:let a=''|g/pattern/y A

See https://twitter.com/gumnos/status/846310953494986752 for more details.

Agreed.  Learn the basics of Vim, get annoyed by it, find a way to change what 
annoys you, put those changes in your .vimrc as you grow and learn more Vim.

What happens if you use the following sequence?

"+y

That should copy the selected (hilighted) text into the X11 clipboard.

"*y

That should copy the selected (hilighted) text into the X11 primary selection 
buffer.

(Where "copy" is subject to the typical X11 issues with the source program 
still being available.)
