# IntelliJ as a Service

Make IntelliJ as a Java server that does autocompletion for Vim.

This is not an official Google product (i.e. a 20% project).

## Installation

1. git clone.

2. Import project into IntelliJ. Use Gradle plugin.

3. Run `gradle buildPlugin`. It creates `build/distributions/ijaas-*.zip` at the

   git root dir. (You can pass `-Pintellij.version=IC-2017.2.6` to specify the

   IntelliJ version.)

4. Select "File" menu and click "Settings...". In "Plugins" menu, click "Install

   plugin from disk..." button. Choose `ijaas-*.zip`. You can uninstall this

   plugin from this menu.

5. Restart IntelliJ.

6. Add "vim" directory to your runtimepath in Vim in your own way.

   (e.g. Plug "$HOME/src/ijaas/vim").

## Development

If you want to isolate your development version and the current version, you

might need two clones. You can load Vim plugins conditionally by using

environment variables.

```

if !exists('$USE_DEV_IJAAS')

  Plug '$HOME/src/ijaas-dev/vim'

else

  Plug '$HOME/src/ijaas/vim'

endif

```

You can start another IntelliJ instance by using `gradle runIdea`. You can pass

`-Dijaas.port=5801` to make the testing IntelliJ process listen on a different

port (see https://github.com/JetBrains/gradle-intellij-plugin/issues/18).

Connect to the testing IntelliJ with `USE_DEV_IJAAS=1 IJAAS_PORT=5801 vim`. The

ijaas vim plugin will recognize `IJAAS_PORT` and use that to connect to the

ijaas IntelliJ plugin.

## Using with ALE

You can define an ALE linter.

```

# Disable buf_write_post. Files are checked by ALE.

let g:ijaas_disable_buf_write_post = 1

# Define ijaas linter.

function! s:ijaas_handle(buffer, lines) abort

  let l:response = json_decode(join(a:lines, '\n'))[1]

  if has_key(l:response, 'error') || has_key(l:response, 'cause')

    return [{

          \  'lnum': 1,

          \  'text': 'ijaas: RPC error: error=' . l:response['error']

          \    . ' cause=' . l:response['cause'],

          \}]

  endif

  return l:response['result']['problems']

endfunction

call ale#linter#Define('java', {

      \   'name': 'ijaas',

      \   'executable': 'nc',

      \   'command': "echo '[0, {\"method\": \"java_src_update\", \"params\": {\"file\": \"%s\"}}]' | nc localhost 5800 -N",

      \   'lint_file': 1,

      \   'callback': function('s:ijaas_handle'),

      \ })

```
