# Cosmos SDK Versions (cosmosver)
|
|
|
|
The `cosmosver` package parses, compares, and detects Cosmos SDK versions used by a chain project.
|
|
|
|
For full API details, see the
|
|
[`cosmosver` Go package documentation](https://pkg.go.dev/github.com/ignite/cli/v29/ignite/pkg/cosmosver).
|
|
|
|
## When to use
|
|
|
|
- Detect the Cosmos SDK version from a project before scaffolding or migrations.
|
|
- Compare versions to enable/disable version-specific features.
|
|
- Access Ignite's known SDK version set and latest supported baseline.
|
|
|
|
## Key APIs
|
|
|
|
- `Detect(appPath string) (version Version, err error)`
|
|
- `Parse(version string) (v Version, err error)`
|
|
- `var Versions = []Version{ ... }`
|
|
- `var Latest = Versions[len(Versions)-1]`
|
|
- `(Version) Is(version Version) bool`
|
|
- `(Version) LT(version Version) bool`
|
|
- `(Version) LTE(version Version) bool`
|
|
- `(Version) GTE(version Version) bool`
|
|
|
|
## Common Tasks
|
|
|
|
- Use `Detect` against a chain root to gate generation paths by SDK version.
|
|
- Parse user-provided versions with `Parse` before comparisons.
|
|
- Branch behavior with `LT`/`GTE` checks against well-known constants.
