# About
The goal of `flatnvim` is to make it easy to use [Neovim](https://neovim.io/)'s
[terminal emulator](https://neovim.io/doc/user/nvim_terminal_emulator.html).
When you open files from within the Neovim terminal, `flatnvim` will automatically add them
to the current instance instead of creating a new nested one.
Now you can easily use all your favorite command line programs inside Neovim.
# Usage
## Clone & Build
You'll first need the `flatnvim` binary on you system.
```sh
git clone https://github.com/adamtabrams/flatnvim.git
cd flatnvim
./build.sh
```
## Environment Variables
There are 4 environment variables `flatnvim` can use.
Add them to the config file for your shell (.bashrc, .profile, .zprofile, etc).
### Required: set the path to the actual editor.
```sh
export FLATNVIM_EDITOR="nvim"
```
- When `flatnvim` is called from your regular terminal, it will just pass arguments to this editor.
### Recommended: set the path to the `flatnvim` binary as your default terminal editor.
```sh
export EDITOR="$HOME/repos/flatnvim/bin/flatnvim"
```
- If you don't know what this should be, use the path printed by the build.sh script.
- In addition, you can make an alias to `flatnvim`: `alias vim="$EDITOR`
### Optional: set a log file for `flatnvim` to use.
```sh
export FLATNVIM_LOGFILE="$HOME/repos/flatnvim/log.txt"
```
- If this is not set, any error messages are just printed.
### Optional: set an extra Neovim command to be executed when preventing nested instances.
```sh
export FLATNVIM_EXTRA_COMMAND="echo 'it works' | sleep"
```
- Just in case you want `flatnvim` to do something extra before it opens files in the parent instance.
## Neovim Configs
### Recommended: disable status line when in terminal mode.
```viml
autocmd TermOpen * setlocal laststatus=0 noshowmode noruler
\| autocmd TermClose * setlocal laststatus=2 showmode ruler
```
### Recommended: skip exit prompt if terminal commands were successful.
```viml
autocmd TermClose * if !v:event.status | exe 'bdelete! '..expand('') | endif
```
### Optional: fix issue with Airline that occurs when window focus is lost.
```viml
autocmd TermLeave * AirlineRefresh
```
## Neovim Function
Adding this function to your Neovim config makes it easier to access the terminal and specific command line programs.
```viml
function! TempTerm(...)
let command = get(a:, 1)
exe "terminal ".command
return ""
endfunction
```
```viml
nnoremap gt :call TempTerm(" ")
nnoremap gL :call TempTerm("lazygit")
nnoremap gl :call TempTerm("lf")
```
