"==================================================
" File: echofunc.vim
" Brief: Echo the function declaration in
" the command line for C/C++, as well
" as other languages that ctags
" supports.
" Authors: Ming Bai <mbbill AT gmail DOT com>,
" Wu Yongwei <wuyongwei AT gmail DOT com>
" Last Change: 2011-06-22 16:34:01
" Version: 1.3
"
" Install: 1. Put echofunc.vim to /plugin directory.
" 2. Use the command below to create tags
" file including the language and
" signature fields.
" ctags -R --fields=+lS .
"
" Usage: When you type '(' after a function name
" in insert mode, the function declaration
" will be displayed in the command line
" automatically. Then you may use Alt+- and
" Alt+= (configurable via EchoFuncKeyPrev
" and EchoFuncKeyNext) to cycle between
" function declarations (if exists).
"
" Another feature is to provide a balloon tip
" when the mouse cursor hovers a function name,
" macro name, etc. This works with when
" +balloon_eval is compiled in.
"
" Because the message line often cleared by
" some other plugins (e.g. ominicomplete), an
" other choice is to show message in status line.
" First, add %{EchoFuncGetStatusLine()} to
" your 'statusline' option.
" Second, add the following line to your vimrc
" let g:EchoFuncShowOnStatus = 1
" to avoid echoing function name in message line.
"
" Options: g:EchoFuncLangsDict
" Dictionary to map the Vim file types to
" tags languages that should be used. You do
" not need to touch it in most cases.
"
" g:EchoFuncLangsUsed
" File types to enable echofunc, in case you
" do not want to use EchoFunc on all file
" types supported. Example:
" let g:EchoFuncLangsUsed = ["java","cpp"]
"
" g:EchoFuncMaxBalloonDeclarations
" Maximum lines to display in balloon declarations.
"
" g:EchoFuncKeyNext
" Key to echo the next function.
"
" g:EchoFuncKeyPrev
" Key to echo the previous function.
"
" g:EchoFuncShowOnStatus
" Show function name on status line. NOTE,
" you should manually add %{EchoFuncGetStatusLine()}
" to your 'statusline' option.
"
" g:EchoFuncAutoStartBalloonDeclaration
" Automatically start balloon declaration if not 0.
"
" g:EchoFuncPathMappingEnabled
" g:EchoFuncPathMapping
" The new feature added by Zhao Cai provides ability
" to shorten file path in some specific directory. e.g.
" /home/username/veryveryvery/long/file/path/blabla
" could be showed as
" ~/veryveryvery/long/file/path/blabla
" If you want to disable this feature, add
" let g:EchoFuncPathMappingEnabled = 0
" to your vimrc. It's enabled by default.
" To add more mappings in g:EchoFuncPathMapping, search
" this script and you will know how to do it.
"
"
" Thanks: edyfox
