SemVerq

Semverq is a cli utility for:

• Validating semver format
• Accessing semver structures
• Convert semver to json

Features

Validation

For -i option, semverq validates the input string as a semver.

$ semverq -i '1.2.3-beta+dev-armhf'
(nothing is output)
$ echo $?
0

$ semverq -i '1.2.3-beta+dev+armhf'
invalid format as semver: 1.2.3-beta+dev+armhf
$ echo $?
150

If the -i option is not specified, semverq reads string from standard input.

$ semverq <<<'1.2.3-input+stdin'
$ echo $?
0

Convert to json

For -j option, semverq converts the input to json.

$ semverq -j -i '1.2.3-beta+36a1d2f'
{
  "major": 1,
  "minor": 2,
  "patch": 3,
  "pre-release": "beta",
  "build": "36a1d2f"
}

If pre-release or build is not exists, the values of their fields will be null.

$ semverq -j -i '1.2.3'
{
  "major": 1,
  "minor": 2,
  "patch": 3,
  "pre-release": null,
  "build": null
}

Accessing to parts

For -q option, access semver parts.

Get only major version:

$ semverq -q '.major' -i '1.2.3-beta+36a1d2f'
1

Build a json object with pre-release and build:

$ semverq -q '{ "pre-release": ".pre-release", "build": ".build" }' -i '1.2.3-beta+36a1d2f'
{ "pre-release": "beta", "build": "36a1d2f" }

Accessor

Supported accessors are below:

• .major Major version.
• .minor Minor version.
• .patch Patch version.
• .pre-release or .pre pre-release version.
• .build Build metadata.
• .version-core Shorthand for .major..minor..patch.

Checking for a match

For -m option, semverq checking for a match to given requirement. The requirement is constructed from comma separated version constraint. This matching syntax and rules are same as in Rust's package system.

Matching case:

$ semverq -m '>1.2.1, <=2.0.0' -i '1.2.3'
$ echo $?
0

Not matching case:

$ semverq -m '^1.2.1, 1.3.*' -i '1.2.3-beta+dev-armhf'
Version (1.2.3-beta+dev-armhf) does not match that requirement (^1.2.1, 1.3.*).
$ echo $?
152

Invalid requirement:

$ semverq -m '>1.2.1, <=2.0.0.' -i '1.2.3'
invalid format as version requirement: >1.2.1, <=2.0.0.
$ echo $?
151
