todocheck

todocheck is a static code analyzer for annotated TODO comments.

It let's you create actionable TODOs by annotating them with issues from any of the supported issue trackers.
No longer will you discover arcane, undocumented TODO comments, scattered across your code base.

See How it works for more info.

How it works

Here's an example of an annotated TODO:

// TODO J123: Fix this typo
func fuu() {
    ...
}

In case the linked issue J123 is open, todocheck will not report any error. In case it is closed or doesn't exist, todocheck will show an error:

ERROR: Issue is closed.
myproject/main.go:12: // TODO J123: Fix this typo

ERROR: Issue doesn't exist.
myproject/main.go:14: // TODO J321: A non-existent issue

If there is an unannotated TODO in your code base, todocheck will also report it as a malformed TODO:

ERROR: Malformed todo.
myproject/main.go:16: // TODO - This is not a valid annotated todo

Only TODOs with valid, open issues are allowed to exist in the codebase.

By integrating todocheck in your development workflow & CI pipeline, you can ensure that there will be no half-baked issue closed with pending TODOs in the codebase.

Installation

Via homebrew

brew install preslavmihaylov/taps/todocheck

Download prebuilt binary

Download the binary for your OS from the latest release.

Optionally verify the sha256 checksum:

• For macos, run shasum -a 256 <binary> & verify it's the same as <binary>.sha256
• For linux, run sha256sum <binary>
• For windows, use a SHA256 checksum utility

Afterwards, verify the shasum is the same as <binary>.sha256.

Place the binary in a folder, shined upon by your $PATH.

• For macos & linux, that's typically /usr/local/bin/

Using a Container

Alternatively to installing the todocheck binary on your system you may use a prebuilt container image from the GitHub container registry, e.g.:

docker run -it -v /path/to/project:/project -e TODOCHECK_AUTH_TOKEN=your_token ghcr.io/preslavmihaylov/todocheck --basepath /project

For a complete list of container tags visit the Packages section on the GitHub project page. For a complete list of docker run options visit the Docker documentation.

Quickstart

First, you need to configure todocheck's integration with your issue tracker. This is done by creating a .todocheck.yaml file in the root of your project.

For public github or gitlab repositories, you don't need to specify a config file, as long as you are using git, as todocheck will interpret your issue tracker from the git configuration.

Alternatively, the explicit configuration for a public github repository would look like this:

origin: github.com/user/repository
issue_tracker: GITHUB

See Supported Issue Trackers for more issue tracker options.

After the config file is in place, simply run todocheck from the root of your project.

In case you are running todocheck from a different directory, you can specify your project's path using the --basepath flag and the project configuration with --config:

$ todocheck --basepath path/to/project --config path/to/config/.todocheck.yaml

If the --config option is not specified, the configuration in the basepath will be used.
In the example above, it would look for it in path/to/project/.todocheck.yaml.

Supported Issue Trackers

Currently, todocheck supports the following issue trackers:

Issue Tracker	Description
Github	Both public & private repositories are supported
Gitlab	Both public & private repositories are supported
Jira	Supported via offline and API tokens
Pivotal Tracker	Supported via an API token
Redmine	Supports public access with no auth & private access via an API token
YouTrack	Supported via an API token
Azure Boards	Supports public access with no auth & private access via an API token

Github

To integrate with a public github repository, there's no need to provide a .todocheck.yaml explicitly as it can automatically detect the issue tracker based on the git remote address. And if you want to be explicit, please specify the origin of your repo and the GITHUB issue tracker in your .todocheck.yaml configuration:

origin: github.com/user/repository
issue_tracker: GITHUB

To integrate with a private github repository, you'll also need to specify the auth section with the apitoken type:

origin: github.com/user/repository
issue_tracker: GITHUB
auth:
  type: apitoken

The first time you run the application, it will ask for your personal access token:

After you've specified it, it will store it in the auth tokens cache for subsequent executions. See the Authentication section for more info.

Gitlab

To integrate with a public gitlab repository, there's no need to provide a .todocheck.yaml explicitly as it can automatically detect the issue tracker based on the git remote address. And if you want to be explicit, please specify the origin of your repo and the GITLAB issue tracker in your .todocheck.yaml configuration:

origin: gitlab.com/user/repository
issue_tracker: GITLAB

To integrate with a private gitlab repository, you'll also need to specify the auth section with the apitoken type:

origin: gitlab.com/user/repository
issue_tracker: GITLAB
auth:
  type: apitoken

The first time you run the application, it will ask for your personal access token:

After you've specified it, it will store it in the auth tokens cache for subsequent executions. See the Authentication section for more info.

Jira

To integrate with your organization's Jira, you'll need to specify JIRA as your issue tracker, the origin of your jira server instance.

Along with that, you'll need to setup auth based on your preferred authentication method.

API Token

To use JIRA with an API token, you'll need to have an Atlassian user which you can use to issue an API token.
You'll also need to specify your Atlassian username.

Example:

origin: https://myawesomeorg.atlassian.net
issue_tracker: JIRA
auth:
  type: apitoken
  options:
    username: [email protected]

For more info on how authentication works, see the Authentication section.

Offline Token

For more info, see offline token.

Example:

origin: https://myjira.awesomeorg.com
issue_tracker: JIRA
auth:
  type: offline
  offline_url: https://myjira.awesomeorg.com/offline

After you run todocheck for the first time, it will request your offline token:

Example offline token page:

After you've given the offline token to todocheck's prompt, it will store it in the auth tokens cache for subsequent executions.

See the Authentication section for more info.

Pivotal Tracker

To integrate with a pivotal tracker project, specify the origin of your project and the PIVOTAL_TRACKER issue tracker in your .todocheck.yaml configuration.
You should also specify the apitoken as an auth type:

origin: pivotaltracker.com/projects/PROJECT_ID
issue_tracker: PIVOTAL_TRACKER
auth:
  type: apitoken

The first time you run the application, it will ask for your API Token.

After you've specified it, it will store it in the auth tokens cache for subsequent executions. See the Authentication section for more info.

Redmine

To integrate with a redmine issue tracker project, specify the origin of your installation (without project path) and the REDMINE issue tracker in your .todocheck.yaml configuration.

You should also specify the apitoken as an auth type if you have authentication enabled on your server:

origin: https://redmine.mycorp.com
issue_tracker: REDMINE
auth:
  type: apitoken

Alternatively, if no authentication is required, don't include the auth section.

The first time you run the application, it will ask for your API Token.

After you've specified it, it will store it in the auth tokens cache for subsequent executions. See the Authentication section for more info.

In order to integrate todocheck with your redmine server, you'll need to enable the server's rest API and, optionally, enable authentication - See Docs.

YouTrack

To integrate with a youtrack project, specify the origin of your project and the YOUTRACK issue tracker in your .todocheck.yaml configuration.
You should also specify the apitoken as an auth type.

For YouTrack InCloud:

origin: youtrack-instance.myjetbrains.com
issue_tracker: YOUTRACK
auth:
  type: apitoken

For YouTrack Standalone:

origin: youtrack-instance.com
issue_tracker: YOUTRACK
auth:
  type: apitoken

The first time you run the application, it will ask for your API Token.

After you've specified it, it will store it in the auth tokens cache for subsequent executions. See the Authentication section for more info.

Azure Boards

To integrate with a public Azure Boards project, you should specify the origin of your project and 'AZURE' as an issue tracker in your .todocheck.yaml configuration.

origin: https://dev.azure.com/your_user/your_public_project/
issue_tracker: AZURE

To integrate with a private Azure Boards project, you'll also need to specify the auth section with the apitoken type:

origin: https://dev.azure.com/your_user/your_private_project/
issue_tracker: AZURE
auth:
  type: apitoken

The first time you run the application, it will ask for your API Token.

After you've specified it, it will store it in the auth tokens cache for subsequent executions. See the Authentication section for more info.

Supported Programming Languages

Currently, todocheck has parsers for three different types of comments:

• Standard comments like // and /* */
• Scripts using single-line comments #
• Python with its # single-line and """ multi-line comments

Based on this, here are the supported languages:

Supported Languages	Description
Bash/Zsh	*.sh/*.bash/*.zsh extension. Supports # single-line comments
C	*.c extension. Supports single-line // comments and multi-line /* */ comments
C++	*.cpp extension. Supports single-line // comments and multi-line /* */ comments
CSharp	*.cs extension. Supports single-line // comments and multi-line /* */ comments
Dart	*.dart extension. Supports single-line // comments and multi-line /* */ comments
Golang	*.go extension. Supports single-line // comments and multi-line /* */ comments
Groovy	*.groovy, *.gvy, *.gy, *.gsh extensions. Supports single-line // comments and multi-line /* */ comments
Java	*.java extension. Supports single-line // comments and multi-line /* */ comments

If you don't see your favorite language in this table, but it does use one of the supported comment formats, submit an issue here

Ignored Files & Directories

If you want certain project files not to be included for todocheck processing, you can specify that in an ignored section in the .todocheck.yaml configuration:

origin: some.origin.com
issue_tracker: JIRA
ignored:
  - vendor-folder/
  - scripts/*.sh

Ignored files/folders can be specified via standard pattern-matching. Hidden files (dotfiles, i.e. .git, .gitignore, etc) are ignored by default.

Custom Todos

By default, todocheck looks for todos in the format // TODO 231: ... Most projects stick to this format.

However, if you have some special todo format, which is different from the default one, you can specify a list of custom todo formats in your .todocheck.yaml

origin: some.origin.com
issue_tracker: JIRA
custom_todos:
  - "@fix"
  - ToDo

Note that this list adds additional formats the tool should match, but doesn't substitute the default one - TODO.

With the above configuration, todocheck will start matching todo comments in the following formats:

// @fix 234: a leftover task...
// ToDo 15: A funky-looking todo comment

In addition to that, you can specify the match_case_insensitive flag to match TODOs in any casing:

origin: some.origin.com
issue_tracker: JIRA
match_case_insensitive: true

With this configuration, todocheck will match comments in similar formats:

// TODO 15: some comment
// ToDO 14: another comment
// tOdO 13: yet another one

Supported Output Formats

Currently, todocheck supports two kinds of output - standard & json.

The standard format is meant to be user-friendly & used in the normal day-to-day workflow.

ERROR: Malformed todo
tmp/main.groovy:2: // TODO: Invalid todo
        > TODO should match pattern - TODO {task_id}:

ERROR: Malformed todo
tmp/main.groovy:12: // TODO: Invalid todo
        > TODO should match pattern - TODO {task_id}:

ERROR: Issue doesn't exist
tmp/main.groovy:15: // TODO 3: A non-existent issue

The json output is meant to be used for integrating todocheck in third-party systems, such as an IDE plugin.
To use json output, use the --format json flag.

[
   {
      "type":"Malformed todo",
      "filename":"tmp/main.groovy",
      "line":2,
      "message":"TODO should match pattern - TODO {task_id}:"
   },
   {
      "type":"Malformed todo",
      "filename":"tmp/main.groovy",
      "line":12,
      "message":"TODO should match pattern - TODO {task_id}:"
   },
   {
      "type":"Issue doesn't exist",
      "filename":"tmp/main.groovy",
      "line":15,
      "message":""
   }
]

Authentication

None

For public repositories, todocheck requires no authentication as the issues in the issue tracker are publicly available. In this case, you need not specify any auth section in your configuration or explicitly set it as none:

origin: github.com/user/repository
issue_tracker: GITHUB
auth: 
  type: none

API Token/Offline Token

For private repositories, todocheck requires an authentication token which the user specifies via a secure prompt.

For github & gitlab, there is a personal access token one can get in his user settings & todocheck can use that to read your repository's issues. Github docs Gitlab docs

To use this authentication type, configure the auth type as apitoken:

origin: github.com/user/repository
issue_tracker: GITHUB
auth: 
  type: apitoken

For Jira, you'll need to specify an offline token:

origin: https://myjira.awesomeorg.com
issue_tracker: JIRA
auth:
  type: offline
  offline_url: https://myjira.awesomeorg.com/offline

An offline token is one which your user can get by accessing a specific page, where your server generates an access token.

Example offline token page:

After you've received either an api token (github/gitlab) or an offline token, you can paste it in todocheck's secure prompt when asked.
Example with github PAT prompt:

Afterwards, todocheck will not ask for your token again as it will store it in its tokens cache.

Authentication Tokens Cache

Whenever a user grants todocheck an auth token, the token will be stored in a file ~/.todocheck/authtokens.yaml.

If that file doesn't already exist, it will be created with read/write permissions for current user only (permission 0700).

This file stores a key-value mapping of project origin to auth token.
Whenever todocheck runs, it first checks this file for an existing authentication token before contacting the issue tracker's server.

If you want to specify a different tokens cache, you can set the tokens_cache section in your .todocheck.yaml configuration:

# remainder omitted
auth:
  # remainder omitted
  tokens_cache: path/to/tokens_cache

Auth Token via Environment Variable

If you need to pass an authentication token via an environment variable, use the TODOCHECK_AUTH_TOKEN environment variable.

Example usage:

TODOCHECK_AUTH_TOKEN=<secret-token> todocheck --basepath path/to/project

This can be useful when you want to integrate todocheck in your CI pipeline.

Configuration

In your .todocheck.yaml configuration, you have the following configuration options:

• origin - the origin of your remote repository/issue tracker (example: github.com/golang/go)
• issue_tracker - the issue tracker type you're using. Possible options - GITHUB, GITLAB, JIRA
• ignored - a list of directories/files todocheck should ignore. Supports pattern-macthing, e.g. *.sh.
• custom_todos - a list of custom todos variables. TODO will always be added. (example: "@fix")
• auth - the authentication configuration for your issue tracker. If not present, it defaults to auth type: none
  • type - the type of authentication. Possible options - none (default), offline, apitokenA
  • offline_url - the url for fetching offline tokens. Only used when type is offline
  • tokens_cache - the location of your auth tokens cache. Defaults to ~/.todocheck/authtokens.yaml

In your tokens cache (default: ~/.todocheck/authtokens.yaml), authentication tokens are stored in the following format:

tokens:
  github.com/user1/repo1: SECRET_TOKEN_1
  gitlab.com/user2/repo2: SECRET_TOKEN_2
  https://jira.awesomeorg.com/offline: SECRET_TOKEN_3

If you'd like to explicitly specify an access token in this file, feel free to do so. This will let the user not have to manually input the token on the first todocheck execution.

This can be used e.g. in a CI environment, in an initial laptop setup script, etc.
Alternatively, use an Auth Token via Environment Variable
