I.e., it concats the strings together, but with a space between. Removing the space from the command line: :echo 'this is a test'strftime('%c')
does not help. It still concats with a space.

Is there a way to concat without the space?

:echon 'this is a test'strftime('%c')

Note: I would normally try to look this up in the VIM help, but it is hard
to search for stuff related to the basic syntax of the language. What
would you search on?

I did :h echo and found echon right below.

You could try ':echon', though...

According to ':h echo' in vim, each expression is printed with a space
between, so it doesn't look like it.

According to other posters downthread, 'echon' solves the problem, for
echo. But (and this is critical), 'echo' is not the point. I was only
using echo for demonstration purposes.

I actually came across this problem in another context, that did not
involve echo. I found that I always got the extra space in there.

So, there needs to be a way to do string concatenation that does not insert
the space.

could be fixed if we can revert this one statistic. Nothing can be fixed until we do.

The only example you gave was with echo, so you were given an
echo-oriented solution. Perhaps if you provide the context in which
you're *actually* encountering the problem that can be addressed.

According to ':h echo' in vim, each expression is printed with a space between, so it doesn't look like it.

Expressions in Vim can be catenated with the dot operator.

For instance :echo "a" . "b" prints ab for me.

Likewise, :echo "a" . strftime('%s') prints aWed...

Thank you!

Yes, that jogs my memory. I had used . previously, but it has been a long time.

I also used it; and by golly there are multiple examples in my now
ancient .vimrc.

Here is one. Well, two:

:nmap K "_y:execute count ? ( ":!man " . count . " " . expand("<cword>") ) : ( ":grep \\<" . expand("<cword>") . "\\>")<CR>
:vmap K "zy:execute ":grep " . getreg("z")<CR>

The built-in K command does man page lookup normally for the word under
the cursor. If you give it a numeric prefix, it will look in that
section of the man system; 2K will do a "man 2 <word>".

I wanted K to do a :grep through the code I'm working on,
but retain the prefixed K functionality for man page lookups.

May not be totally appropriate to mention this here (if not apologies in advance) but this is another resource for Vi/Vim questions: https://vi.stackexchange.com

Since this is the only thread I've seen recently in comp.editors that
isn't spam (or trash) I wanted to try to contribute something worthwhile
to the conversation.
