go-install operation

Install a tool through go install.

This is done in a way that is shareable across work directories managed by omni; i.e. once a tool is installed in a given version, if required from another work directory it will not need to be reinstalled.

This will automatically install a version of go if none is available through omni to run the go install command, but won't add it to the dynamic environment.

Parameters

Parameter	Type	Description
path	string	The <path> part of go install <path>[@<version>]
version	string	The version to install; see version handling below for more details.
exact	boolean	Whether to match the exact version or not; if set to true, go install <path>@<version> will be called directly instead of listing the available versions and following the version handling rules (default: false)
upgrade	boolean	whether or not to always upgrade to the most up to date matching release, even if an already-installed version matches the requirements (default: false)
prerelease	boolean	Whether to download a prerelease version or only match stable releases; this will also apply to versions with prerelease specification, e.g. 1.2.3-alpha. Ignored when exact is set to true (default: false)
build	boolean	Whether to download a version with build specification, e.g. 1.2.3+build. Ignored when exact is set to true (default: false)

Version handling

The following strings can be used to specify the version:

Version	Meaning
1.2	Accepts 1.2 and any version prefixed by 1.2.*
1.2.3	Accepts 1.2.3 and any version prefixed by 1.2.3.*
~1.2.3	Accepts 1.2.3 and higher patch versions (1.2.4, 1.2.5, etc. but not 1.3.0)
^1.2.3	Accepts 1.2.3 and higher minor and patch versions (1.2.4, 1.3.1, 1.4.7, etc. but not 2.0.0)
>1.2.3	Must be greater than 1.2.3
>=1.2.3	Must be greater or equal to 1.2.3
<1.2.3	Must be lower than 1.2.3
<=1.2.3	Must be lower or equal to 1.2.3
1.2.x	Accepts 1.2.0, 1.2.1, etc. but will not accept 1.3.0
*	Matches any version (same as latest, except that when upgrade is false, will match any installed version)
latest	Latest release (when upgrade is set to false, will only match with installed versions of the latest major)

The version also supports the || operator to specify ranges. This operator is not compatible with the latest and keywords. For instance, 1.2.x || >1.3.5 <=1.4.0 will match any version between 1.2.0 included and 1.3.0 excluded, or between 1.3.5 excluded and 1.4.0 included.

The latest version satisfying the requirements will be installed.
