Installation

The core packages of the Gonum suite are written in pure Go with some assembly. Installation is done using go get.

go get -u gonum.org/v1/gonum/...

Supported Go versions

Gonum supports and tests using the gc compiler on the two most recent Go releases on Linux (386, amd64 and arm64), macOS and Windows (both on amd64).

Note that floating point behavior may differ between compiler versions and between architectures due to differences in floating point operation implementations.

Release schedule

The Gonum modules are released on a six-month release schedule, aligned with the Go releases. i.e.: when Go-1.x is released, Gonum-v0.n.0 is released around the same time. Six months after, Go-1.x+1 is released, and Gonum-v0.n+1.0 as well.

The release schedule, based on the current Go release schedule is thus:

  • Gonum-v0.n.0: February
  • Gonum-v0.n+1.0: August

Build tags

The Gonum packages use a variety of build tags to set non-standard build conditions. Building Gonum applications will work without knowing how to use these tags, but they can be used during testing and to control the use of assembly and CGO code.

The current list of non-internal tags is as follows:

  • safe — do not use assembly or unsafe
  • bounds — use bounds checks even in internal calls
  • noasm — do not use assembly implementations
  • tomita — use Tomita, Tanaka, Takahashi pivot choice for maximimal clique calculation, otherwise use random pivot (only in topo package)

Issues TODOs

If you find any bugs, feel free to file an issue on the github issue tracker. Discussions on API changes, added features, code review, or similar requests are preferred on the gonum-dev Google Group.

Functions

func Version 

func Version() (version, sum string)

Version returns the version of Gonum and its checksum. The returned values are only valid in binaries built with module support.

If a replace directive exists in the Gonum go.mod, the replace will be reported in the version in the following format: 

"version=>[replace-path] [replace-version]"

and the replace sum will be returned in place of the original sum.

The exact version format returned by Version may change in future.
