Vim/makevim

The script I use to build vim:

1. !/bin/sh
2. vim: ft=sh :

verbose='no'

die() { echo $2 exit $1 } required() { x=`which $1 2>&1` if [ ! -x "$x" ] then die 100 "'$1' not found. Make sure it is installed and in your PATH" fi } verbose() { if [ "$verbose" == "yes" ]; then echo $1; fi }

1. findvim:

vimdir="" for v in ~/proj/vim /c/vim ~/src/vim do if [ -d $v ] then if [ -d $v/src ] then vimdir=$v break fi else v=${v}7 if [ -d $v ] then if [ -d $v/src ] then vimdir=$v break fi fi fi done

if [ "$vimdir" == "" ] then die 1 "Cannot determine the VIM directory. Please update script" fi

1. are we doing a cross-compile for Windows?

cross='no' rawos=`uname` os="?" if [ "$rawos" == "Darwin" ]; then os="Mac" ; fi if [ "$rawos" == "Linux" ]; then os="Lin" ; fi if [ "$rawos" == "MINGW32_NT-5.1" ]; then os="Win" ; fi

if [ "$os" == "?" ] then die 1 "I don't know what the OS ${rawos} is. Please update script" fi nowhere="/dev/null" if [ "$os" == "Win" ] then nowhere="NUL" fi

1. check for required programs:

for p in diff ncftpls ncftpget patch gawk sed sort grep tail ; do required $p ; done

clean() { verbose "Cleaning previous VIM build" cd $vimdir make distclean 2>&1 > $nowhere cd - }
