Codo

The code comment TODO tool

Make TODO comments powerful with Codo, a command-line tool to search, manage, format, and validate your codebase's TODO comments.

Installation

Codo is distributed as a Rust crate, so Rustup and then run:

cargo install codo

TODO anatomy

Codo-style TODO comments have these shapes:

// TODO: Simple example with no metadata
// TODO(@chris): Example TODO assigned to "chris"
// TODO(#123): Example TODO citing Github-like issue "#123"
// TODO(PROJ-123): Example TODO citing a Jira-like issue
// TODO(2023-11-01): Example TODO with a due date of November 1st, 2023
// TODO(#123, @chris, 2023-11-01): Example of all three metadata pieces

Don't worry about the syntax too much though, codo format and codo validate as shown below will keep up the hygiene.

Basic commands

Search TODOs

# list all TODOs
codo list

# list all overdue TODOs
codo list --overdue

# list all unassigned TODOs
codo list --unassigned

# list all TODOs assigned to someone
codo list --assignee=chris

Get TODO stats

# Get total TODO count 
codo stat

# Get TODO count by assignee
codo stat --group-by=assignee

Format TODOs

codo format

This command rewrites TODO comments into proper form. For examples:

// TODO example
// todo example
// ToDo example
//    TODO: example

All get formatted to // TODO: example. Version control is highly recommended, especially when running this command as it modifies files in-place.

Validate TODOs

Have TODO hygiene you'd like to enforce? This command is for you:

codo validate
  --require-assignees
  --require-due-dates
  --require-issues

This command will return a non-zero exit status and print out validation errors if there are any. A great tool to add to your pre-push/commit hooks and CI pipeline to force consistency.

Export TODOs

codo export json

Prints out JSON in this shape:

{
  "version": "<current codo version>",
  "todos": [
    {
       "assignee": "chris",
        "due": "2023-11-01",
        "issue": "#123",
        "line": 42,
        "note": "This is an example",
        "path": "./README.md"
    }
  ]
}

Various code mods

There are code mods you can use to manipulate TODOs. Some cool ones:

# Assign all TODOs which lack an issue with issue #123
codo mod add-issue-for-all-untracked --issue="#123"

# Bulk update TODO assignees
codo mod rename-assignee --from="old_name" --to="new_name"
