`ic-query` provides the `icq` executable for read-only Internet Computer
metadata queries.
`icq` currently supports NNS and SNS metadata queries: registry version,
subnet catalog lookup, node/provider/operator/data-center inventory, topology
reports, and deployed SNS listings.
## Install
From this checkout:
```sh
make install
```
From crates.io after publication:
```sh
cargo install ic-query
```
## Commands
```sh
icq nns help
icq nns registry version
icq nns subnet [list|info|refresh]
icq nns node [list|info|refresh]
icq nns node-provider [list|info|refresh]
icq nns node-operator [list|info|refresh]
icq nns data-center [list|info|refresh]
icq nns topology [summary|coverage|versions|health|gaps|capacity|regions|providers|refresh]
icq sns [list|info|token]
icq sns neurons [refresh]
```
Use `icq nns <family> help`, `icq nns topology <report> help`, or
`icq sns <command> help` for command options.
Most commands support text output by default and JSON output with
`--format json`:
```sh
icq --network ic nns subnet info ryjl3-tyaaa-aaaaa-aaaba-cai --format json
```
## Cache
The NNS subnet, node, provider, operator, data-center, and topology commands
use project-local cache files under `.icq/`. Refresh commands fetch current
mainnet registry data and replace the matching cache atomically:
```sh
icq nns subnet refresh
icq nns topology refresh
```
List/info commands populate their component cache on first use and print the
API endpoint they are calling before creating it. Refresh commands force a
fresh fetch and replace the matching cache.
SNS neuron commands keep quick `--sort api` output on a bounded live query.
Whole-collection neuron sorts use complete snapshots:
```sh
icq sns neurons refresh 1
icq sns neurons 1 --limit 500 --sort stake
```
Complete SNS neuron snapshots live under
`.icq/sns/ic/<root-principal>/neurons/full.json`. Failed or capped refresh
attempts are recorded separately and do not replace the last complete snapshot.
Refresh shows a same-line stderr progress counter with pages and rows fetched
when running in a terminal.
Live API neuron listings are capped at 100 rows per call. Cache-backed sorts
can use larger `--limit` values because they read from the complete local
snapshot.
Neuron IDs are shortened to eight characters in text tables by default. Use
`icq sns neurons 1 --verbose` to show full neuron IDs.
Text output shows current SNS token amounts, including token fee, total supply,
stake, maturity, and staked maturity, as token decimals with two places. JSON
keeps the raw base-unit and e8s fields.
## Development
This repository pins the local toolchain to Rust `1.96.0` while declaring
Rust `1.91.0` as the crate MSRV.
```sh
make fmt-check
make clippy
make test
make package
```
The combined local gate is:
```sh
make ci
```
Release version bumps are available after the release contents are committed and
the worktree is clean:
```sh
make patch
make minor
make major
```
Each target runs `make test`, bumps `Cargo.toml` and `Cargo.lock`, validates the
package, commits the release version, and creates an annotated `vX.Y.Z` tag.
Use the Canic-style release targets to push the release commit and tag after
the same gate succeeds:
```sh
make release-patch
make release-minor
make release-major
```
## Integration
`icq` is a standalone metadata lookup tool. Orchestration, deployment, and
application repositories can call the CLI when they need IC metadata instead of
linking registry adapters directly. For one integration example, see
[Canic](https://github.com/dragginzgame/canic).
## Status
The command namespace is intentionally small:
- `nns` is implemented.
- `sns list`, `sns info`, `sns token`, and `sns neurons` are implemented for
deployed mainnet SNS instances.
- `sns neurons refresh` caches complete neuron snapshots for cache-backed
sorting.
- Additional IC query families can be added without coupling query code to
deployment tooling.
