Todo.sh add-ons let you add new todo.sh actions or change (override) default actions. Visit the Todo.sh Add-on Directory to find browse available add-ons.
Installing Add-ons
Add-ons can be installed into the $HOME/.todo.actions.d directory or any other directory configured via $TODO_ACTIONS_DIR.
Create this directory with the following bash shell commands:
You must name add-ons after the action you want to add or override. For example, create a new "review" action by installing an add-on to .todo.actions.d/review.
After installing the add-on, you must make it executable.
For example:
Use the new or overridden action the normal todo.sh way.
For example:
You can force todo.sh to use a default action instead of an overridden action by prefixing the action's name with the word, "command".
For example:
Creating Add-ons
Add-ons may be written in any programming language your operating system supports. The first command-line argument to the add-on will be the action called or the word "usage"; the remaining arguments, if any, will be those provided by the user. For example:
If the first argument is usage, you should provide a short usage message that will be displayed when the user calls todo.sh -h.
Todo.sh will also provide your script with several environmental variables including the following documented in todo.sh's usage message:
TODOTXT_PRESERVE_LINE_NUMBERS
TODOTXT_VERBOSE
TODOTXT_PLAIN
TODOTXT_AUTO_ARCHIVE
TODOTXT_FORCE
TODOTXT_DATE_ON_ADD
and the following environmental variables not documented in the usage message:
TODO_SH - name of the todo.sh script, use in the usage message
TODO_FULL_SH - complete path to calling todo.sh script, use for invoking todo.sh
TODOTXT_CFG_FILE - complete path to user's todo.sh configuration file
TODO_DIR - complete path to the todo.txt file
Aliasing Add-ons
You may want to allow short aliases for those new commands (e.g. "pv" as alias for "projectview")
There is a small issue if you simply duplicate or symlink the add-on file: the corresponding help snippet will be duplicated as well in the output of the todo.sh help command. To avoid that, you can create aliases by creating short add-ons such as this example (replace projectview by the command you want to call with your alias):
