This patch does 2 things:
- Allowing environment variables corresponding to options (e.g. VERBOSE for -v)
to be predefined in the user environment instead of having to always use
the corresponding option.
- Adding namespace TODOTXT_ to those envvars to avoid clashes in user environment
todo.action.d scripts can call recursively todo.sh and this patch preserves
the options/envvars through the calls.
As a bonus, now the user can export in advance one of those variables in
his/her environment and it would have the same effect as using the todo.sh
corresponding option.
export TODOTXT_AUTO_ARCHIVE=0 is same as option -a
export TODOTXT_CFG_FILE=CONFIG_FILE is same as option -d CONFIG_FILE
export TODOTXT_FORCE=1 is same as option -f
export TODOTXT_PRESERVE_LINE_NUMBERS=0 is same as option -n
export TODOTXT_PLAIN=1 is same as option -p
export TODOTXT_DATE_ON_ADD=1 is same as option -t
export TODOTXT_VERBOSE=1 is same as option -v
