.zshenv file syntax: spanning lines with comments

.zshenv file syntax: spanning lines with comments

[Benjamin Drago]

This is not a serious problem; just one I've been curious about.

Is there a way to have long variables span multiple lines, with
comments inserted?  Something like this:

current version:

export PATH=/home/$USER/bin/$OSTYPE:/home/$USER/bin:/usr/local/bin:/opt/gnu/bin:/usr/bin:/usr/sbin:/usr/X11R6/bin:/vol/local/$OSTYPE/bin

what I would like to do:

export PATH=/home/$USER/bin/$OSTYPE:		# arch dependent binaries
	/home/$USER/bin:			# arch independent scripts
	/usr/local/bin:				# local apps
	/opt/gnu/bin:				# gnu tools
	...


Thanks,
Ben

Why are you using `/home/$USER' instead of `~' ?

How about this:

----- snip ----- 8< ---- snip -----

setopt magic_equal_subst		# for `export foo=~/bar`
function export() { EXPORT=${1%%\=*} ; typeset -Ux $* }
function +() { eval builtin export ${EXPORT}=\$\{$EXPORT\}:\$1 }

export PATH=/home/$USER/bin/$OSTYPE	# arch dependent binaries
	+	/home/$USER/bin		# arch independent scripts
	+	/usr/local/bin		# local apps
	+	/opt/gnu/bin		# gnu tools
	+	...

unfunction export +

----- snip ----- 8< ---- snip -----

Now you can even do stuff like:

export PATH=~/bin/$OSTYPE		# arch dependent binaries
	+	~/bin			# arch independent scripts
				    case $OSTYPE in
				    sun*)
	+	$OPENWINHOME/bin	# openwindows applications
	+	/usr/ccs/bin		# compiler tools
	+	/opt/bin		# optional packages
				    ;;
				    *)
	+	/usr/bin/X11		# X11 applications
				    ;;
				    esac
	+	/usr/local/bin		# local apps
	+	/opt/gnu/bin		# gnu tools
	+	...

I like that so much I might even rewrite my own .zshenv ...

What about good old $HOME?

The simplest way is probably to use $path instead. That is a list
variable that is kept in sync with $PATH

path=(  /home/$USER/bin/$OSTYPE			# arch dependent binaries
	/home/$USER/bin				# arch independent scripts
	/usr/local/bin				# local apps
	/opt/gnu/bin				# gnu tools
	...
     )

(It works for me, at least)
