Programming Scheme(Racket) with VIM - How to get s

问题:

recently, I started programming Racket (formerly Scheme) in DrRacket. I quite fast I began to miss all the features of VIM in DrRacket, so I would like to use VIM for my scheme(racket) programming.

I know that Emacs might be the best choice for intense lisp programming, but all I want is write a scheme(racket) file check syntax and then run it.

Unfortunately, I could not figure out, how to invoke "racket" in the commandline on a file to get it doing the same as DrRacket.

I am running Ubuntu 10.10 Maverick Meerkat, VIM 7.3 and I downloaded and installed Racket from the official website.

Help to get started would be very appreciated.

If you just want to load a file into Racket on the command-line and run it, I think that this should work:

$ racket -f file.scm -i

The -i option would leave you at the REPL to test your code in file.scm.

However, you might want to take a look at this blog post:

You can set up a GNU screen session running the command-line Racket, and send s-expressions to it from Vim. There's a link to a bit of Vimscript which will make this automatic. I used this for a while with mit-scheme, and it was reasonably effective. It's not quite the as powerful as SLIME or DrRacket though. I just tested the steps described on OS X and it works with the command-line racket, it should work on Ubuntu, that's what I was using when I first used this method.

You might also want to take a look at this:

http://evalwhen.com/scmindent/index.html

... which has some information on better indentation in Vim for Lisp and Scheme code.

I eventually switched to Emacs, but don't let the Vim haters get you down. Paul Graham supposedly uses vi and he's gotta be one of the top 5 most prominent Lisp programmers.

Several add-ons are available to make coding in Racket more satisfying with Vim.

• Vim’s lisp mode (set lisp) -- improves some basics for indenting and w/e/b word-hopping.
• vim-racket -- sizable set of vim-syntax recognition for functions and syntax
• syntastic -- identify errors upon save (vim-racket sets makeprg for this to work)
• Rainbow Parentheses -- set your own paren colors for maximal contrast!
• vim-slime -- use with Tmux to connect Vim to a Racket REPL
• surround -- wrap forms and elements in parens
• vim-sexp for normal people
• Molokai color scheme -- high contrast
• VROD* -- K-based Vim documenation, and auto-completion of Racket functions
• REPTL* -- very simple continuous rackunit test runner

I prefer slime over slimv for its simplicity.

If you are using Vundle, here is a way to install most of the add-ons mentioned:

Plugin 'tpope/vim-surround.git'
Plugin 'kien/rainbow_parentheses.vim'
Plugin 'scrooloose/syntastic.git'
Plugin 'MicahElliott/vrod'
Plugin 'guns/vim-sexp'
Plugin 'tpope/vim-sexp-mappings-for-regular-people'
Plugin 'wlangstroth/vim-racket'
Plugin 'tomasr/molokai.git'

Put those into your ~/.vimrc, and then invoke to install:

% vim +PluginInstall +qall

Here is a screenshot showing off most of these:

(* disclosure: I wrote VROD and REPTL, and they are immature)

Also, here is a related blog post describing a Vim/SICP setup.

As of about a week ago, SLIMV (SLIME for Vim) supports Racket. SLIMV is generally regarded as the most mature Lisp environment for Vim at the moment.
