Ⅱ. 基本信息

创建日期：  2004-01-31 使用用户：  3 Github星：  7 插件作者：  Tom Link

Ⅲ. 安装方法

使用Vundle管理器安装

在你的.vimrc下添加:

Plugin '/evalselection-vim'

… 然后在Vim中运行以下命令:

:source %
:PluginInstall

对于Vundle版本 < 0.10.2，请用上面的Bundle替换Plugin。

使用NeoBundle管理器安装

在你的.vimrc下添加:

NeoBundle '/evalselection-vim'

… 然后在Vim中运行以下命令:

:source %
:NeoBundleInstall

使用VimPlug管理器安装

在你的.vimrc下添加:

Plug '/evalselection-vim'

… 然后在Vim中运行以下命令:

:source %
:PlugInstall

使用Pathogen管理器安装

在终端中运行以下命令:

cd ~/.vim/bundle
git clone https://github.com/vim-scripts/EvalSelection.vim

Ⅳ. 文档说明

Evaluate source code selected in a visual region. The result can be displayed
in an interaction log, appended to the text, replace the text, or saved in the
@e register. This is useful for performing small text manipulation tasks or
calculations that aren't worth the trouble of creating a new file or switching
to a different program, but which are too big for being handled in the command
line.

The key bindings follow this scheme:

    <Leader>e{LANGUAGE}{MODE} :: work on the visual region
    <Leader>E{LANGUAGE}{MODE} :: work on the contents of the e-register
    <Leader>x{MODE}           :: work on the visual region (derives LANGUAGE
                                 from the buffer's 'filetype')

LANGUAGE being one of:

    v :: vim (comments at the end of line after vim code could cause problems)
    r :: ruby (requires compiled-in ruby support)
    s :: sh (using system())
    e :: calculator, evaluate formula (using either ruby, python, perl, tcl,
         or vim)

I haven't actually tested the following three bindings because I use
neither of them. Anyway, as I happen to use a Vim with +tcl, +python and
+perl support compiled in, I added them to the standard bindings:

    y :: python (requires compiled-in python support)
    p :: perl (requires compiled-in perl support)
    t :: tcl (requires compiled-in tcl support)
    z :: mzscheme (requires compiled-in mzscheme support)

If ruby-support is compiled in, the following languages are available too
(but see |EvalSelection-Interaction| below):
    
    c :: scheme
        set g:evalSelectionSchemeInterpreter to "Gauche" or "Chicken"
    l :: lisp
        set g:evalSelectionLispInterpreter to "CLisp"
    o :: ocaml
        set g:evalSelectionOCamlInterpreter to "OCaml" or "OCamlClean"
    R :: R
        set g:evalSelectionRInterpreter "R", "RClean", or "RDCOM"
    S :: SPSS
        limited support (no return values), the (one-way) communication with
        SPSS is done via OLE automation

MODE being one of:

    x :: just evaluate and put the result in the e-register
    e :: the same as x
    p :: echo/print the result on the command line
    a :: append the result to visual region
    r :: replace visual region with the result
    l :: insert the result in a temporary interaction log

Commands:

    EvalSelectionCmdLine LANG :: Simulate a command line for LANG; due to the
    primitive handling of input/output, no input commands (like read, get kind
    of stuff) can be used; all output is redirected to the log. Exit with ^D +
    Enter, i.e. enter the ^D character.

    EvalSelectionSetup{LANG}  :: Set up interaction with external interpreter
    (but see below)

    EvalSelectionQuit INTERPRETER :: Quit interaction with an
    external interpreter
