#9849 feat: Show required setting indicators in `meltano config list` Pull request opened by mahangu Description

meltano config <plugin> list

output can be large (SDK plugins have many settings), and users have no way to tell which settings are required vs optional. Plugins already define

settings_group_validation

(array of arrays, each inner array is a valid combination of required setting names) but this metadata was never surfaced in the CLI. This PR adds visual cues to

meltano config list

output: • Group summary header printed before the settings list when validation groups exist. For multiple groups it shows each valid combination; for a single group it lists the required settings. • Per-setting labels annotated inline: •

(required)

— setting appears in all validation groups (always needed) •

(required by group N)

— setting appears in only some groups • No annotation for optional settings Example output for `tap-gitlab`:

Setting groups (one of the following combinations is required):
  Group 1: api_url, groups, start_date
  Group 2: api_url, projects, start_date

api_url (required) [env: TAP_GITLAB_API_URL] current value: '<https://gitlab.com>' (default)
groups (required by group 1) [env: TAP_GITLAB_GROUPS] current value: '' (default)
projects (required by group 2) [env: TAP_GITLAB_PROJECTS] current value: '' (default)
start_date (required) [env: TAP_GITLAB_START_DATE] current value: None (default)

Plugins without

settings_group_validation

(including

meltano

itself) are unaffected.

meltano config list

CLI output. New Features: • Display a summary of settings validation groups before the

config list

output when plugins define settings group validation. • Annotate individual settings in

config list

with required-status labels based on the validation groups. Tests: • Extend CLI config list tests to cover required-setting labels, group summaries, and behavior when no or a single validation group is defined. • Add tests for the helper that formats required-setting labels from group membership metadata. meltano/meltano
