How can I define a shell function (named `:` would be neat) from a terminal buffe and send commands to current vim clientr?

[陈世用]

Like in a terminal buffer, typing:

```
$ :vsp demo.file
```

`:` is the custom shell function's name.

It's expand to `<c-w>:vsp demo.file` or something.

I think it is unclear, what you are asking exactly. Please clarify.

Best,
Christian

Sound like you want a terminal mapping. I think :help tmap may give you what you want, but if you remap the colon, you'll have trouble if you need to use it in an actual command. You could either map the double colon (::) to do this or to insert an actual single colon:

tmap : <c-w>:

tnoremap :: :

Or, depending on which you prefer, reverse the two mappings.

No, not a tmap. I know tmap. 

What I want is, to invoke vim command from a terminal with shell commands, without typing <c-w> prefix or entering normal mode. 

Like providing a shell function ‘send-keys-to-host-vim’ (and I want its name be ‘:’), then run

$ send-keys-to-host-vim vsp my.file<enter>

It equals to <c-w>:vsp my.file<enter>

Sorry for my poor English, hope it is explained clearly this time.

Salman Halim,

Your mapping idea seems good. I will try it. Thanks.

Have a look at `:h terminal-api`. I have a plugin that does something
similar: https://github.com/chrisbra/vpager you can also have a look
there.
