Use: "configure",
Short: "Configure a new bridge.",
Long: ` Configure a new bridge by passing flags or/and using interactive terminal prompts. You can avoid all the terminal prompts by passing all the necessary flags to configure your bridge.
Repository configuration can be made by passing either the --url flag or the --project and --owner flags. If the three flags are provided git-bug will use --project and --owner flags.
Token configuration can be directly passed with the --token flag or in the terminal prompt. If you don't already have one you can use the interactive procedure to generate one.`,
Example: `# Interactive example
[1]: github
[2]: launchpad-preview
target: 1
name [default]: default
Detected projects:
[1]: github.com/a-hilaly/git-bug
[2]: github.com/MichaelMure/git-bug
[0]: Another project
Select option: 1
[1]: user provided token
[2]: interactive token creation
Select option: 1
You can generate a new token by visiting https://github.com/settings/tokens.
Choose 'Generate new token' and set the necessary access scope for your repository.
The access scope depend on the type of repository.
Public:
- 'public_repo': to be able to read public repositories
Private:
- 'repo' : to be able to read private repositories
Enter token: 87cf5c03b64029f18ea5f9ca5679daa08ccbd700
