What have you tried by yourself so far to come to this conclusion at the |
| 8 |
end? Or is it not much more as a guess while you are waiting for a |
| 9 |
solution from the list? |
| 10 |
|
| 11 |
There are so many resources out there. Have you ever searched for it? |

From which terminal emulator are you talking about? And of course, are |
| 15 |
you using ‘app-editors/vim’, ‘app-editors/vim-core’, USE=minimal or even |
| 16 |
‘app-editors/neovim’? |
| 17 |

You have to deal with terminal escape sequences which may cause |
| 20 |
headaches. Vim usually inherits its terminal options from the terminfo |
| 21 |
file (man 5 terminfo) specified by the ${TERM} variable or at command |
| 22 |
line as argument for the parameter ‘-T’. |
| 23 |
|
| 24 |
Within Vim’s command line invoke (without the quotes) ‘:set termcap’ to |
| 25 |
see what is currently set in your Vim session. To get an idea what those |
| 26 |
output means, read the help at ‘:help terminal-options’. But it may be |
| 27 |
worth to check first Vim is able to set cursor shape/colour related |
| 28 |
stuff by running: |
| 29 |
vim --version |
| 30 |
or within Vim any of: |
| 31 |
:version |
| 32 |
:echo has('cursorshape') |
| 33 |
and look it is compiled with the '+cursorshape' feature. |
| 34 |
|
| 35 |
When it is, you can set the related terminal options (‘t_SI’, |
| 36 |
‘t_SR’, ‘t_EI’). Read — once more — the most obviously resource: |
| 37 |
:help termcap-cursor-shape |
| 38 |
:help termcap-cursor-color |
| 39 |
for an example. As an additional hint, you can set both (shape and |
| 40 |
colour) by concatenating terminal escape sequences. For instance: |
| 41 |
let &t_SI = "\<Esc>]12;purple\x7\<Esc>[5 q" |
| 42 |
sets a purple blinking IBeam cursor for insert mode (or globally, if you |
| 43 |
are not reset the cursor style for the other modes). |
| 44 |
|
| 45 |
Because you aren’t disclose your terminal emulator, I have to stop here. |
| 46 |
|
| 47 |
The mentioned headaches maybe starts when: |
| 48 |
• you are expect a ready to use solution and/or unwilling to |
| 49 |
understand the basics of terminal escape sequences |
| 50 |
• you only want to style the cursor in Vim (not those in the terminal) |
| 51 |
• you are using different shapes/colours for different modes |
| 52 |
• you are using different terminal emulators (local/remote) |
| 53 |
• you are running terminal multiplexer > terminal emulator > Vim |
| 54 |
• your system lacks the required terminfo file |
| 55 |
• annoying side effects appears (e.g. with alternate screen) |
| 56 |
• … |
| 57 |
|
| 58 |
But there are solutions for those issues (except for point one). |

Why *what* fails? How can you expect an appropriate answer with so |
| 62 |
sparsely informations from your side? |
