[deoplete.nvim](https://github.com/Shougo/deoplete.nvim) source for F#
Using [deopletefs](https://github.com/callmekohei/deopletefs) that is command-line interface to the [FSharp.Compiler.Service](https://github.com/fsharp/FSharp.Compiler.Service).
It's useful to write a small code in F# script file ( .fsx ) .
## Requires
[mono](https://github.com/mono/mono) ( >= Mono 5.4.0 )
[fsharp](https://github.com/fsharp/fsharp)
## Install

$ git clone --depth 1 https://github.com/roxma/vim-hug-neovim-rpc
// install
$ cd ./deoplete-fsharp/
$ bash install.bash ( or install.cmd )
// set runtimepath
$ vim .vimrc
set runtimepath+=/path/to/deoplete
set runtimepath+=/path/to/deoplete-fsharp

set runtimepath+=/path/to/deoplete-fsharp
```
Example of deoplete setting
```vim
" .vimrc ( or init.vim )
autocmd MyAutoCmd VimEnter *.fsx,*.fs call s:foo()
function s:foo() abort
call deoplete#custom#option({
\ 'auto_refresh_delay' : 20
\ , 'min_pattern_length' : 999
\ , 'ignore_case' : v:true
\ , 'refresh_always' : v:false
\ , 'ignore_sources' : {'fsharp':['member']}
\ })
call deoplete#enable()
endfunction

## 01. Run
![alt text](./pic/quickrun2.png)
### Requires
[vim-quickrun](https://github.com/thinca/vim-quickrun)
[vimproc.vim](https://github.com/Shougo/vimproc.vim)
### Install and build
```
// download
$ git clone --depth 1 https://github.com/thinca/vim-quickrun
$ git clone --depth 1 https://github.com/Shougo/vimproc.vim
// build
$ cd ./vimproc/
$ make
// set runtimepath
$ vim .vimrc
set runtimepath+=/path/to/vim-quickrun
set runtimepath+=/path/to/vimproc.vim
```
### Example of vim-quickrun setting
```vim
" .vimrc ( or init.vim )
let g:quickrun_config = {}
let g:quickrun_config._ = {
\ 'runner' : 'vimproc'
\ ,'runner/vimproc/updatetime' : 60
\ ,'hook/time/enable' : 1
\ ,'hook/time/format' : "\n*** time : %g s ***"
\ ,'hook/time/dest' : ''
\ ,"outputter/buffer/split" : 'vertical'
\ ,'outputter/buffer/close_on_empty' : 1
\}
let g:quickrun_config.fsharp = {
\ 'command' : 'fsharpi --readline-'
\ ,'runner' : 'concurrent_process'
\ ,'runner/concurrent_process/load' : '#load "%S";;'
\ ,'runner/concurrent_process/prompt': '> '
\}
```
If you use window's Vim / Neovim
```
'command': 'mono "path\to\fsi.exe" --readline-'
```
### Run F# script file
```
: w
: QuickRun
```
## 02. Test
![alt text](./pic/persimmon2.png)
### Requires
[Persimmon.Script](https://github.com/persimmon-projects/Persimmon.Script)
### Install ( requires [Paket](https://github.com/fsprojects/Paket) )
```
// make foo folder and move to foo folder
$ mkdir foo/
$ cd foo/
// install
$ paket init
$ vim paket.dependencies
generate_load_scripts: true
source https://www.nuget.org/api/v2
nuget persimmon.script
$ paket install
```
### Test F# script file
```
: w
: QuickRun
```
### Sample code
```fsharp
#load "./.paket/load/net471/main.group.fsx"
open Persimmon
open UseTestNameByReflection
open System.Reflection
/// write your test code here.
let ``a unit test`` = test {
do! assertEquals 1 2
}
/// print out test report.
new Persimmon.ScriptContext()
|> FSI.collectAndRun( fun _ -> Assembly.GetExecutingAssembly() )
```
