Files with ANSI escape sequences look good when dumped onto a terminal that accepts them, but heretofore have been a distracting clutter when edited via vim.  The AnsiEsc.vim file, when sourced with vim 7.3 or later, will conceal Ansi escape sequences but will cause subsequent text to be colored as the escape sequence specifies.

You need to have a vim with conceal mode enabled; use has("conceal") to find out if the vim you're using has that feature.

Without that conceal feature or with vim versions earlier than 7.3, the best that can be done is to suppress Ansi escape sequences with "Ignore" highlighting.  AnsiEsc.vim v2 does that.

Cutting edge versions are available at http://www.drchip.org/astronaut/vim/index.html#ANSIESC .

Usage:  edit a file containing escape sequences, then type :AnsiEsc

AnsiEsc.vba.gz 12 2010-12-13 7.0 Charles Campbell * changed conc -> cole for vim 7.3's built-in conceal mode
* included some additional escape sequences
AnsiEsc.vba.gz 11 2010-06-22 7.0 Charles Campbell supports several escape sequences such as <esc>[m , <esc>[2J, and <esc>[H.
AnsiEsc.vba.gz 10 2010-04-07 7.0 Charles Campbell AnsiEsc has 1 and 2 Ansi escape code sequences supported by fixed syntax highlighting rules; it now also builds custom syntax highlighting to support 3 and 4 Ansi Escape code sequences based on your current document.  So  \e[48;5;16m will now cause correct highlighting to follow, for example.
AnsiEsc.vba.gz 9 2009-03-18 7.0 Charles Campbell * AnsiEsc comes in plugin + autoload format: faster vim startup, and AnsiEsc only when you want it.
* Now provides a :AnsiEsc command totoggle ANSI escape sequence processing.

Works with Vince Negri's conceal patch (if your vim supports VN's conceal, then the ansi-escape sequences are suppressed except on the line you're editing).
AnsiEsc.vba.gz 8 2006-08-16 7.0 Charles Campbell Uses vim7.0's undercurl as a substitute for blinking (which Vim doesn't support), contains a small helpfile, and contains directions for getting Vince Negri's conceal patch for vim 7.0.
AnsiEsc_v2.vim 2 2004-11-24 6.0 Charles Campbell I mistakenly removed AnsiEsc v2 (which is the version which doesn't use Vince Negri's conceal).  This update restores it!
