# el.sh --- insert html elements using sh
### Code:
## Escape < and > with backslashes.
EL_ESCAPE=true
el() { # el NAME ARGS...
## Create an HTML element named NAME using ARGS.
# Any ARGS that contain an equals sign will be made into attributes of the
# element, until the special argument '--' which will stop attribute
# processing. While some nesting is possible with 'el', the way bash
# expansion works it's not great.
#
# No validation is done on any arguments in this function. It could create
# something that looks vaguely like an HTML element but isn't valid.
_name="$1"
shift || return 1 # Require at least an element name
_element="$_name"
_content=""
_process_args=true
while test -n "$1"; do
case "$1" in
--)
if "$_process_args"; then
_process_args=false
else
_content="$_content${_content:+ }$1"
fi
;;
'\<'*)
_process_args=false
_content="$_content${_content:+ }$1"
;;
*=*)
if "$_process_args"; then
_element="$_element ${1%%=*}=\"${1#*=}\""
else
_content="$_content${_content:+ }$1"
fi
;;
*)
if "$_process_args"; then
_process_args=false
fi
_content="$_content${_content:+ }$1"
;;
esac
shift
done
if $EL_ESCAPE; then
fmt='\<%s\>%s\</%s\>\n'
else
fmt='<%s>%s</%s>\n'
fi
printf "$fmt" "$_element" "$_content" "$_name"
}
### HTML5 element aliases
## These come from https://developer.mozilla.org/en-US/docs/Web/HTML/Element
# To avoid clobbering the shell's namespace, a prefix is used. Change this
# variable when sourcing el.sh in order to change or disable the prefix. E.g.:
# $ EL_PREFIX= . ./el.sh
# $ EL_PREFIX=HTML . ./el.sh
: "${EL_PREFIX:=_}"
