Installation

Install via Binary

Releases are available on Github at https://github.com/zephinzer/dev/releases.

Install via Go

You can also install it via go install:

go install github.com/zephinzer/dev

Install via Make

Clone this repository and run make install:

git clone [email protected]:zephinzer/dev.git;
cd dev;
make install;

Test the installation works by running dev -v.

Usage

dev loads its configuration from the home directory and the current working directory from which dev is run. A file is considered a configuration file if it matches a pattern of ^.dev(.labels)+.yaml$. Some examples of valid configuration file names are:

1. .dev.yaml
2. .dev.github.yaml
3. .dev.gitlab.yourdomain.com.yaml
4. .dev.some1elses.yaml

Repository Management

To automate this with some degree of sanity, some strongly-opinionated assumptions are made:

1. Your repositories shall be stored in your home directory using the path <hostname>/<username>/<path-to-repo>. For example, this repo will be stored at /home/${USER}/github.com/zephinzer/dev
2. You operate your IDE using workspaces to reference the repositories so that the exact repository location on your hard drive does not matter
3. You use SSH keys to authenticate with your source control management platform

Configuring repositories

Repositories are configured using the repositories root level property in the configuration file as such:

# ...
repositories:
- description: working repository for the dev tool
  name: dev (do work here)
  url: [email protected]/zephinzer/dev.git
  workspaces: [productivity, development]
- description: public repository for the dev tool
  name: dev (install from here)
  url: [email protected]/zephinzer/dev.git
  workspaces: [productivity, production]
# ...

The structure for each repository item can be found at ./pkg/repository/repository.go. In summary the fields are:

Field	Required	Default	Description
description	No	""	An arbitrary description displayed in dev metadata only
name	No	""	An arbitrary name displayed in dev metadata only
path	No	~/${HOSTNAME}/${REPO_PATH}	The path on your local machine to put this repository
url	Yes	-	The URL to this repository. dev will always convert this to an SSH clone URL
workspaces	No	[]	A list of workspace names that this repository should belong to

Checking repositories setup

To verify that all repositories have been installed locally, use:

dev check repositories;

Cloning all listed repositories

If a repository is listed in the configuration but is not available locally, it's possible to clone it using this tool using:

dev install repos;

Known issue #1: You won't be able to clone a bare repository.

Known issue #2: If you have a long list of repositories, some might fail because too many requests are being made to the server.

Exporting workspaces from repositories

If you've defined the workspaces property for your repositories, you can export repositories related to a workspace by using:

# get the workspace ${WORKSPACE_NAME}
dev get workspace ${WORKSPACE_NAME};

Exporting workspace directly to a file

Use the --output-directory/-o flag to export it directly to the current directory (a file at ./${WORKSPACE_NAME}.code-workspace will be created):

# export to the current directory
dev get workspace ${WORKSPACE_NAME} --output-directory .;

To export it directly to /some/path/at (a file at /some/path/at/${WORKSPACE_NAME}.code-workspace will be created):

# export to the directory at /some/path/at
dev get workspace ${WORKSPACE_NAME} -o /some/path/at;

If the file already exists, dev will complain. Use the --overwrite/-O flag to tell it to overwrite the file:

# export to the directory at /some/path/at, overwriting it if the target file exists
dev get workspace ${WORKSPACE_NAME} -o /some/path/at --overwrite;

Exporting workspace in a different format

To change the formatting of the workspace, use the --format/-f flag:

dev get workspace ${WORKSPACE_NAME} -f vscode;

The following workspace formats are supported:

1. Visual Studio Code/Codium (format name: vscode)

Software Management

The software management feature allows developers to check whether required software have been installed and if not, to install them.

Configuring softwares

Software is configured using the root level softwares property in the configuration file as such:

# ...
softwares:
- name: brew
  description: used for system dependency installations
  platforms: [macos]
  check:
    command: [brew, --version]
    stdout: ^Homebrew
  install:
    link: https://brew.sh/
- name: node
  description: used for the primary projects
  check:
    command: ["node", "-v"]
    stdout: ^v\d+\.\d+\.\d+$
  install:
    link: https://github.com/nvm-sh/nvm#installing-and-updating
- name: terraform
  description: used for bringing up our infrastructure
  check:
    command: ["terraform", "version"]
    stdout: ^Terraform v\d+\.\d+\.\d+$
  install:
    link: https://www.terraform.io/downloads.html
# ...

The structure for each software item is detailed in the ./pkg/software directory and a summary follows:

Field	Required	Default	Description
name	No	""	An arbitrary name displayed in dev outputs when metadata is required
check	Yes	-	Declarative instructions describing how to check for the software's presence
check.command	Yes	-	A list of strings that form the command to check for the software. For example, if you run go version in your CLI to check for Go, the list will look like ["go", "version"]
check.stdout	No	""	A regex-compatible string to match with the command's output on stdout
check.stderr	No	""	A regex-compatible string to match with the command's output on stderr
check.exitCode	No	0	An integer exit code to match with the command's exit code
description	No	""	An arbitrary description of how the software is used/why it's needed displayed in dev outputs when metadata is required
install	No	-	Declarative instructions describing how to install the software if it's not found
install.link	No	""	A link to direct users to if the software is not found installed on the current machine
platforms	No	-	A list of platform strings that define which operating systems this check is valid for. Valid lists are subsets of {linux, windows, macos}. When not specified, does not check for platform compatibility.

Checking software setup

To run checks on the software available locally:

dev check software;

Network Management

Traditionally, teams/organisations typically have internal networks (intranets) for developers to access where privately owned code is pulled from/pushed to. This feature assists the developer to see what networks exist and to verify they have access to the networks they should have access to.

Configuring networks

Networks are configured using the root level networks property in the configuration file as such:

# ...
networks:
- name: internet
  check:
    url: https://google.com
- name: internal-vpn
  registrationUrl: https://openvpn.internal.com
  check:
    url: https://gitlab.internal.com
# ...

The structure of each network can be found in the ./pkg/network directory, a summary is as follows:

Field	Required	Default	Description
name	No	""	An arbitrary name for the network to be displayed in dev metadata when required
registrationUrl	No	""	A URL for users to request access to this network if applicable
check	Yes	-	Declarative instructions on what to check for
check.url	Yes	-	A URL to ping that should be accessible if network connectivity to this network has been established
check.method	No	"GET"	The HTTP method to use to ping the provided check.url
check.statusCode	No	^2\d\d$	The expected HTTP status code of the response to the ping
check.headers	No	{}	A dictionary of expected headers
check.responseBody	No	""	A regex-compatible string that the response body should be expected to match with. Does not apply if not specified/an empty string is provided

Checking network setup

To run a check on your required network connectivity:

dev check networks;

Link Directory

This feature assists with awareness of team resources by providing a list of resources that a developer can use to explore the team's resources.

Configuring links

The link directory is configured using the root level links property in the configuration file as such:

links:
- label: official source-of-truth release repository
  categories: [scm]
  url: https://gitlab.com/zephinzer/dev
- label: dev tool build pipeline
  categories: [cicd]
  url: https://gitlab.com/zephinzer/dev/pipelines
- label: dev tool release pipeline
  categories: [cicd, release]
  url: https://travis-ci.org/github/zephinzer/dev/
- label: dev tool code quality checks
  categories: [cicd]
  url: https://codeclimate.com/github/zephinzer/dev
- label: dev tool releases
  categories: [cicd, release]
  url: https://github.com/zephinzer/dev/releases

The structure for each link object can be found in the ./internal/link directory and a summary follows.

Field	Required	Default	Description
label	No	""	An arbitrary label for this link to be included in link metadata
categories	No	[]	A hashtag-based way of searching to be included in link metadata
url	Yes	-	The URL to open if this link is selected

Using the link directory

To activate the link directory from the terminal, run:

dev goto;

Template Repositories

Being able to create new repositories based on a pre-defined list of templates makes it easy to do the right thing for developers by providing an easy way to kickstart a new service in a organisation/team-approved manner.

Configuring repository templates

Repository templates can be configured using the configuration key at dev.repository/.templates which should be an array of template objects as such:

# ...
dev:
  # ...
  repository:
    templates:
    - name: test for bare repository
      url: https://github.com/zephinzer/template-bare
    - name: golang repository
      url: https://gitlab.com/zephinzer/template-go-package
    # ...
  # ...
# ...

The structure for each template object can be found at ./internal/config/dev.go and a summary follows.

Field	Required	Default	Description
name	NO	""	An arbitrary label used to identify this repository template
url	YES	-	One of the template repository's HTTP URL, HTTPS clone URL, or SSH clone URL

Creating a repository from a template

dev init repo ./path/to/new/repo;

## output:
## > choose a repository template to use
## > 1. ...
## > 2. ...
##
## > your selection (enter 0 to skip):

Platform integrations

Github

The Github integration is not refined for use yet, try it at your own risk!

Setting up Github integration

Retrieve your accessToken by generating a new personal access token from https://github.com/settings/tokens/new. You'll need the following scopes:

• repo:status
• repo_deployment
• public_repo
• repo:invite
• read:packages
• read:org
• read:public_key
• read:repo_hook
• notifications
• read:user
• read:discussion
• read:enterprise
• read:gpg_key

An example follows of a configuration:

# ...
platforms:
  # ...
  github:
    accounts:
    # ...
    - name: personal github
      description: my own stuff
      accessToken: ...
      public: false
    # ...
# ...

Using the Github integration

dev get github account;
dev get github notifs;

Gitlab

The Gitlab integration is not refined for use yet, try it at your own risk!

Setting up Gitlab integration

Retrieve your accessToken by generating a new personal access token from https://gitlab.com/profile/personal_access_tokens. You'll need the following scopes:

• api
• read_api

If you're using an on-premise Gitlab, change gitlab.com to your Gitlab's hostname

Using the Gitlab integration

dev get gitlab account;
dev get gitlab notifs;

Pivotal Tracker

Setting up Pivotal Tracker integration

Retrieve your accessToken from https://www.pivotaltracker.com/profile and enter it as the accessToken as a property at platforms.pivotaltracker

Example:

# ...
platforms:
  # ...
  pivotaltracker:
    accessToken: ...
# ...

Configuring specific Pivotal Tracker projects

1. Navigate to the project you want to receive work/notifications from
2. From the URL, extract the project ID (assuming a URL like https://www.pivotaltracker.com/n/projects/1234567, the project ID is 1234567)
3. Add an array item to the property at platforms.pivotaltracker.projects. The array item has a structure containing 3 properties:
   1. name: an arbitrary label you can use to identify the project
   2. projectID the project ID as retrieved from above as a string (surround with "double quotes" to be sure)

Example:

# ...
platforms:
  # ...
  pivotaltracker:
    accessToken: ...
    projects:
    - name: (some arbitrary name you use to identify your project)
      projectID: "1234567"
    # ... other projects ...
# ...

Using the Pivotal Tracker integration

dev get pivotal account;
dev get pivotal notifs;

Trello

The Trello integration is not refined for use yet, try it at your own risk!

Setting up Trello integration

1. Retrieve your accessKey from https://trello.com/app-key.
2. Generate your accessToken from the link to Token from the above link
3. Enter the accessKey and accessToken as properties at platforms.trello

Example:

# ...
platforms:
  # ...
  trello:
    accessKey: ...
    accessToken: ...
# ...

Configuring Trello boards

The boards property at platforms.trello.boards takes in an array of board shortlinks. You can retrieve a board's shortlink by visiting the board in your browser and extracting it from the URL.

Assuming your board can be found at the URL https://trello.com/b/xxxxxxxx/lorem-ipsum, the board shortlink is xxxxxxxx.

Example:

# ...
platforms:
  # ...
  trello:
    # ... api keys ...
    boards:
    - xxxxxxxx
# ...

Using the Trello integration

dev get trello account;
dev get trello notifs;

Notification integrations

Telegram

dev is able to notify you via Telegram if the integration has been set up.

Setting up Telegram notifications integration

1. Talk to The BotFather using /start if you haven't talked to it before.
2. Send the /newbot command to create a new bot. Give your bot a logical name (eg. "My Notification Bot") followed by a bot username (eg. my_notification_bot).
3. You should receive an access token of the form 1234556789:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX, add the access token at the property dev.client.notifications.telegram.token.
4. Run dev init telegram notifs
5. Talk to your bot and you should see a chat ID appear in dev's logs
6. Copy and paste this chat ID to the property dev.client.notifications.telegram.id as a string (surround the ID with quotes)
7. To test the integration, ensure your chat ID is in the configuration, and run dev debug notifications and confirm you receive a notification in Telegram

Your configuration should look like:

# ... other properties ...
dev:
  # ... other properties ...
  notifications:
    telegram:
      token: 1234556789:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
      id: "987654321"
# ... other properties ...

Other Notes

On output

All output that's prefixed with a log level is being sent to stderr.

To display just stderr output, append 2>/dev/null to your command.

All output that appears as-is without a log level is being sent to stdout

To display just stdout output, append 1>/dev/null to your command.

On exit codes

Exit codes are bitmasks of error types which are docuemnted at ./internal/constants/exit_codes.go.

Type	Value	Indication
OK	0	Success
System	1	An error occurred at the system level
User	2	An error occurred because of user actions
Input	4	An error occurred because of user input
Configuration	8	An error occurred because of the consumed configuration
Application	16	There's likely a bug
Validation	32	Some expected values seem off
Number of errors	128-255	When such an exit code is encountered it's a count of failed iterations from a requested operation, take $((256 - $?)) to get the number of errors from the operation

On debugging

Two global flags are made available to improve debuggability by increasing the amount of logs.

• --debug: display DEBUG level logs (this prints start and end messages, and input/output values)
• --trace: display TRACE level logs (this prints all sorts of nonsense but could be useful sometimes)
