I only mention this here because OGDL seems to address very prettily one of the smaller, simpler problems that Lua handles, one that was fairly central in Lua's birth (as I understand it), specifying structured data. <URL:http://ogdl.org/> OGDL isn't a programming language, like Lua. Instead, it's just a data specification language. It uses indentation to specify a tree structure. [Actually, there are provisions for handling generalized directed graphs, but they can be viewed as an add-on]. I've been using Lua as the spec file language for a software packaging tool I'm developing. I just stumbled across OGDL and it lured me away. Here are my bash spec files, in Lua: pkg = "bash-2.05b"; url = [[ http://mirrors.kernel.org/gnu/bash/bash-2.05b.tar.gz http://downloads.linuxfromscratch.org/bash-2.05b-2.patch ]]; build = [[ tar xzf bash-2.05b.tar.gz cd bash-2.05b ./configure --enable-static-link --with-curses \ --prefix=/ --mandir=/usr/share/man --infodir=/usr/share/info make make prefix=$BPM_ROOT mandir=$BPM_ROOT/usr/share/man \ infodir=$BPM_ROOT/usr/share/info install ln -s bash $BPM_ROOT/bin/sh rm -f $BPM_ROOT/usr/share/info/dir find $BPM_ROOT -type f|xargs file|grep 'ELF.*executable'|sed 's/:.*$//'|xargs strip ]]; and OGDL: pkg bash-2.05b url http://mirrors.kernel.org/gnu/bash/bash-2.05b.tar.gz http://downloads.linuxfromscratch.org/bash-2.05b-2.patch build \ tar xzf bash-2.05b.tar.gz cd bash-2.05b ./configure --enable-static-link --with-curses \ --prefix=/ --mandir=/usr/share/man --infodir=/usr/share/info make make prefix=$BPM_ROOT mandir=$BPM_ROOT/usr/share/man \ infodir=$BPM_ROOT/usr/share/info install ln -s bash $BPM_ROOT/bin/sh rm -f $BPM_ROOT/usr/share/info/dir find $BPM_ROOT -type f|xargs file|grep 'ELF.*executable'|sed 's/:.*$//'|xargs strip Like I said, this is mostly off-topic for this list; please direct followups to me unless they are talking about Lua. -Bennett
