feat(registry): add --json flag to registry command by jdx · Pull Request #7290 · jdx/mise

jdx · 2025-12-14T18:04:40Z

Summary

Adds --json / -J flag to mise registry command
JSON output includes: short name, backends, description (when available), and aliases
Works with existing filters (--backend, --hide-aliased) and single tool lookup

Example Output

$ mise registry --json | head -20
[
  {
    "short": "1password",
    "backends": [
      "vfox:mise-plugins/vfox-1password",
      "aqua:1password/cli"
    ],
    "description": "Password manager developed by AgileBits Inc",
    "aliases": [
      "1password-cli",
      "op"
    ]
  },
  ...
]

$ mise registry node --json
{
  "short": "node",
  "backends": [
    "core:node"
  ],
  "description": "Node.js® is a free, open-source..."
}

Test plan

mise registry --json outputs all tools as JSON array
mise registry <tool> --json outputs single tool as JSON object
mise registry --json --backend cargo filters correctly
mise registry --json --hide-aliased works correctly
Build passes
Lint passes

Note

Adds structured JSON output to mise registry (supports single tool and list, respects --backend and --hide-aliased), with docs, manpage, tests, usage spec, and autocomplete updates.

CLI/Registry:
- Add -J --json flag to mise registry with structured output: short, backends, optional description, and aliases.
- Supports single-tool output and listing; honors --backend and --hide-aliased.
- Refactor: introduce filter_backends, filtered_tools, to_output, and display_json helpers.
Docs/Help:
- Update usage in docs/cli/registry.md, docs/cli/index.md, and man/man1/mise.1 to include -J --json.
- Update mise.usage.kdl spec for the new flag.
Tests:
- Add JSON-focused e2e tests in e2e/cli/test_registry.
Autocomplete:
- Update Fig spec (xtasks/fig/src/mise.ts) to expose -J/--json for registry.

Pull request overview

This PR adds JSON output support to the mise registry command through a new --json / -J flag. The JSON format includes tool metadata (short name, backends, description, aliases) and works seamlessly with existing filtering options.

Key Changes:

Added --json flag to enable structured JSON output instead of table format
Introduced RegistryToolOutput struct to serialize registry tool data
JSON output supports both listing all tools (array) and single tool lookup (object)

+            }
+        };


The filter_backend closure is duplicated in both display_json and display_single_json methods. Extract this into a shared helper method to improve maintainability and reduce code duplication.

+                    backends: backends.iter().map(|s| s.to_string()).collect(),


The backends are already strings from filter_backend, so calling .to_string() creates unnecessary allocations. Since filter_backend returns a cloned collection, you can use the backends directly without the extra iteration and string conversion.

Suggested change

backends: backends.iter().map(|s| s.to_string()).collect(),
