Visible Spaces

[Stewart Johnson]

Hi All -

Sorry if this obvious but I couldn't find anything in :help or google.

Is there a vim option to represent space characters in a file as a dot
or something else not blank?

Thanks,
Stewart

Re: Motions in visual(line|block)

[Stewart Johnson]

I didn't know either, but from my testing it seems to do something like:

move to the start of the current scope and format (indent) everything
in the current scope.

at least that's what it seems to do for me. ;-)

Max,

OK, I'll bite. What does =a{ do? The = is a format, and the {
moves to the start of a class (at least that's what is does in the ruby
file I tested this on). So, what's the a do in this command? Lord
knows, anything that annoys my Visual Studio colleagues is all right
with me.

 I've noticed that using some motions - specifically i{ and suchlike -
 will cancel a visual line/block and turn it into regular visual mode
 instead, which is rather annoying. Is this intentional, or a bug?

 I should just mention that my new favourite command is =a{, which
 makes me smile every time I use it, and which really annoys my Visual
 Studio using colleagues.

 Chairs!

Network access from vim

[Stewart Johnson]

Hey all --

I looked through the vim FAQ/help but wasn't able to find any
information about network access from within vim, so I thought I'd ask
about it here.

I want to initiate commands from within vim to access a specific
server for information -- a TCP/IP connection, probably a HTTP query
on top of that. Is this possible from within vim, or do I need to use
the system function to call some helper app on the host operating
system?

If I have to use a helper app, what's the best way to detect and act
on the operating system environment.

Thanks,
Stewart

Thanks Tony. I looked at that, but it doesn't support generic TCP
sockets, nor does it support HTTP writing. I need to be able send and
receive information with a remote service, and netrw only does half
the job.

Does the client-server stuff in vim use TCP sockets? Is that API
available to scripts?

Thanks,
Stewart

 From within Vim, use

:help pi_netrw.txt


HTH,
Tony.

I didn't get exactly what you are trying to do .. but you have the
option to use python, ruby 
from python you can call any C function.. So it should no problem to
create a TCP connection.. ;-)


Wait, what? I can access python and ruby from within a vim script?

What I'm trying to do is to write a vim script that will take some
information from the current open buffer, send it to a web service,
receive information back from the webservice, and display it in the
vim buffer (and another buffer). Everything I need is available in vim
scripting, apart from being able make HTTP POSTs to webservices.

It looks like I can't make an arbitrary TCP connection from within vim
(please correct me if I'm wrong!) so I'll need to use the system()
function in my vim script to do that (like netrw does). And since I
want it to be cross-platform, I'll need to do a bunch of operating
system snooping to figure out what I can use to make the network
access.

Here's another resource for you that may be helpful:

* http://not.upbylunch.com/2006/05/16/wordpress-posting-vim-script/

This person wrote an script in python that does some rpc stuff (using
the MetaWebLog API) and it can be invoked from within Vim.  This should
help you get started if you want to create something for yourself.

Hope that helps!

Thanks for the info guys, that's very helpful. I've never used a
version of vim with python/perl/ruby compiled into it, so that's a
whole new world for me.

Thanks!
