Agda integration for Vim-8.1

Simple agda integration with vim. It runs a single agda process for your vim session and communicates with it using pipes which are in vim-8.1. It is also using brand new popup windows which just landed in vim. So you'd likely need to compile vim from git.

The plugin includes:

• agda syntax script
• literate agda syntax script
• filetype plugin with the following commands and maps (check ftplugin/agda.vim):
  • :AgdaLoad - load current file, mapped to <LocalLeader>l
  • :AgdaMetas - list goals
  • :AgdaStart - start agda process (done automatically)
  • :AgdaStop - stop agda process
  • :AgdaRestart - restart agda process
  • :AgdaVersion - report version of agda
  • :AgdaRefine - refine a value, mapped to <LocalLeader>r
  • :AgdaAuto - solve current goal by using Auto, mapped to <LocalLeader>a
  • :AgdaInfer [expr] - infer and normalise type of expression, if expr not given use current goal, mapped to <LocalLeader>t
  • :AgdaAbort - abort last operation
  • <LocalLeader>c - map which opens a popup with current goal context
  • <LocalLeader>s - reads current keyword and reporpts where it comes from

It supports both {! !} and ? goals. Some commands, e.g. :AgdaAuto will pass the inner part of {! !}.
