Create and manage devcontainer configuration.


The preferred method is to use cargo binstall.

$ cargo binstall tyedev

Alternatively, download the appropiate release asset. Then extract and copy as needed.

$ shasum --check tyedev-*.sha256
$ tar -xzf tyedev-*.tar.gz
$ cp tyedev-*/tyedev ~/.local/bin

The last method is to use the Github CLI with the redraw/gh-install extension.

$ gh ext install redraw/gh-install
$ gh install CodeMan99/tyedev


Use --help to see help on input flags.

$ tyedev --help
Create and manage devcontainer configuration

Usage: tyedev [OPTIONS] [COMMAND]

  completions  Generate shell auto-complete configuration
  init         Create new devcontainer
  inspect      Display details of a specific feature, template, or collection
  list         Overview of collections

All of the commands depend on a local copy of the generated collection index.

$ tyedev --pull-index --verbose

The tyedev application is organized into sub-commands.

tyedev init

Use to start a new project. Provide no arguments for the default interactive experience.

$ tyedev init --help
Create new devcontainer

Usage: tyedev init [OPTIONS]

  -z, --non-interactive               Avoid interactive prompts
  -s, --attempt-single-file           Write to ".devcontainer.json" when using an `image` type template
  -v, --verbose...                    More output per occurrence
  -q, --quiet...                      Less output per occurrence
  -r, --remove-comments               Strip comments from the generated devcontainer.json
  -t, --template-id <OCI_REF>         Reference to a Template in a supported OCI registry
  -f, --include-features <OCI_REF>    Add the given features, may specify more than once
      --include-deprecated            Include deprecated results when searching
  -w, --workspace-folder <DIRECTORY>  Target workspace for the devcontainer configuration
  -h, --help                          Print help

Note that --remove-comments is not yet actually supported. A better jsonc library would be helpful. May need to write my own.

tyedev inspect

$ tyedev inspect --help
