Usage: grml_theme_add_token <name> [-f|-i] <token/function> [<pre> <post>]
return value is expected in the \$REPLY parameter. The use of these
options is mutually exclusive.
+ There is a utility function \`grml_theme_has_token', which you can use
+ to test if a token exists before trying to add it. This can be a guard
+ for situations in which a \`grml_theme_add_token' call may happen more
+ than once.
+
Example:
To add a new token \`day' that expands to the current weekday in the
shift 2
fi
- if (( ${+grml_prompt_token_default[$name]} )); then
+ if grml_theme_has_token $name; then
printf '
grml_theme_add_token: Token `%s'\'' exists! Giving up!\n\n' $name
