Macos – iterm vim colorscheme not working

itermmacosvim

When I run vim from the command line in iTerm, syntax highlighting doesn't seem to work locally.

In vim for example I have installed a nice colorscheme that works quite well in MacVim but it would be great if in iTerm it showed the same one.

Any ideas how I can turn this on?

This is the color scheme I'm trying to use

That color scheme looks like it only supports 256-color terminals. If Vim thinks that your terminal only supports 8 colors, you won't see that specific color scheme.

You can check this in Vim by:

:echo &t_Co

If that returns 8, this might be the problem. Try setting it to 256 in your ~/.vimrc and see if that helps:

let &t_Co=256

Use `\r` instead of `\n`.

Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.

echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt

Before:
0000000: 6261 720a                                bar.
After:
0000000: 000a 720a                                ..r.

In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.

yy or Y to copy the line (mnemonic: yank)
or
dd to delete the line (Vim copies what you deleted into a clipboard-like "register", like a cut operation)

then

p to paste the copied or deleted text after the current line
or
P to paste the copied or deleted text before the current line
