vim-cpid

This is a vim plugin that aims to provide a few IDE-like niceties within a conventional vim experience. The primary focus is removing the tedium of java’s import requirements. The plugin does the work of identifying the types used in a source file and the types imported into a source file. It relies on cpid to index java types and provide fast lookup for type names.

A few commands provided:

• CheckForMissingImports - Identifies the type names that have been used but not imported.

• ReindexClasspath - Uses Maven to generate a classpath and then asks cpid to index it.

• ReindexProject - Crawls the current directory recursively for .java files and indexes the type names and package names found therein.

• FixMissingImports - Provides a menu to select the package from which each missing import should be satifies.

A couple debugging commands:

• CpidReconnect - Primarily for recovering if you ever after to restart cpid.

• CpidDebugOn / CpidDebugOff - In case you want to help debug the plugin.

The plugin does not perform any checks automatically. You need to configure it to do so. This is how I do it, using my ftplugin/java.vim configuration file:

import "javacp.vim"

augroup CpidJavaTemp
	autocmd!
	autocmd BufRead *.java :call javacp.InitializeJavaBuffer()
	autocmd BufWrite *.java CheckForMissingImports
    autocmd InsertLeave *.java :call javacp.UpdateBufferShadow()
    autocmd TextChanged *.java :call javacp.UpdateBufferShadow()
    autocmd QuickFixCmdPost *.java :call javacp.UpdateBufferShadow()
augroup END

This causes the buffer to be checked for missing imports each time I save the file. I also setup a custom statusline to show an icon when there are missing imports:

function! JavaStatusLineExpr()
    return s:javacp.StatusLineExpr()
endfunction

setlocal statusline=%-f%=%{%JavaStatusLineExpr()%}%l,%c\ %p%%\
highlight CpidStatus guifg=drew_orange  guibg=drew_skyblue

Running the :FixMissingImports command then prompts me like so:

Prerequisites

• The plugin currently assumes you’re using maven.

• In order to propertly extract the JDK version from your pom.xml file you need to have xmlstarlet installed.
