A biased approach to the PEP 440 semantic version. Provides a tuple structure which is sorted for comparisons `v1 > v2` etc. (major, minor, micro, release type, pre-release build, post-release build, development release build) Release types are named in is such a way they are comparable with ease. Accessors to check if a development, pre-release, or post-release build. Also provides accessor to get development status for setup files. How it works (currently): - You must specify a release type as either `final`, `alpha`, `beta`, or `candidate`. - To define a development release, you can use either `.dev`, `.dev-alpha`, `.dev-beta`, or `.dev-candidate`. The dot is used to ensure all development specifiers are sorted before `alpha`. You can specify a `dev` number for development builds, but do not have to as implicit development releases are allowed. - You must specify a `pre` value greater than zero if using a prerelease as this project (not PEP 440) does not allow implicit prereleases. - You can optionally set `post` to a value greater than zero to make the build a post release. While post releases are technically allowed in prereleases, it is strongly discouraged, so we are rejecting them. It should be noted that we do not allow `post0` even though PEP 440 does not restrict this. This project specifically does not allow implicit post releases. - It should be noted that we do not support epochs `1!` or local versions `+some-custom.version-1`.

Behavior is modeled after what we see in browsers. Browsers seem to evaluate if the value is out of range, and if not, it is in range. So a missing value will not evaluate out of range; therefore, value is in range. Personally, I feel like this should evaluate as neither in or out of range.

This is of course requires the parser to provide us with the proper prefix and namespace info, if it doesn't, there is nothing we can do.

A biased approach to the PEP 440 semantic version. Provides a tuple structure which is sorted for comparisons `v1 > v2` etc. (major, minor, micro, release type, pre-release build, post-release build, development release build) Release types are named in is such a way they are comparable with ease. Accessors to check if a development, pre-release, or post-release build. Also provides accessor to get development status for setup files. How it works (currently): - You must specify a release type as either `final`, `alpha`, `beta`, or `candidate`. - To define a development release, you can use either `.dev`, `.dev-alpha`, `.dev-beta`, or `.dev-candidate`. The dot is used to ensure all development specifiers are sorted before `alpha`. You can specify a `dev` number for development builds, but do not have to as implicit development releases are allowed. - You must specify a `pre` value greater than zero if using a prerelease as this project (not PEP 440) does not allow implicit prereleases. - You can optionally set `post` to a value greater than zero to make the build a post release. While post releases are technically allowed in prereleases, it is strongly discouraged, so we are rejecting them. It should be noted that we do not allow `post0` even though PEP 440 does not restrict this. This project specifically does not allow implicit post releases. - It should be noted that we do not support epochs `1!` or local versions `+some-custom.version-1`. Acceptable version releases: ``` Version(1, 0, 0, "final") 1.0 Version(1, 2, 0, "final") 1.2 Version(1, 2, 3, "final") 1.2.3 Version(1, 2, 0, ".dev-alpha", pre=4) 1.2a4 Version(1, 2, 0, ".dev-beta", pre=4) 1.2b4 Version(1, 2, 0, ".dev-candidate", pre=4) 1.2rc4 Version(1, 2, 0, "final", post=1) 1.2.post1 Version(1, 2, 3, ".dev") 1.2.3.dev0 Version(1, 2, 3, ".dev", dev=1) 1.2.3.dev1 ``` r r �major�int�minor�micro�release�str�pre�post�dev�returnc s� |||||fD ]}t |t�r|dkstd��q|tvr#td|� d���d| k r-dk rDn n|dkr7td��|r=td��|rCtd ��n#|d k r[|d krT|dkrTtd ��|rZtd ��n |ratd ��|rgtd��t� �| |||||||�S )zValidate version info.r z6All version parts except 'release' should be integers.�'z ' is not a valid release type.r r z"Implicit pre-releases not allowed.z%Version is not a development release.z0Post-releases are not allowed with pre-releases.r r z!Implicit pre-release not allowed.z Version is not a pre-release.)� isinstancer � ValueError�REL_MAP�super�__new__) �clsr r r r r r r �value�� __class__� �E/usr/local/CyberCP/lib/python3.10/site-packages/soupsieve/__meta__.pyr S s2 ���zVersion.__new__�boolc C � t | jdk�S )zIs prerelease.r )r% r ��selfr# r# r$ �_is_pre{ � zVersion._is_prec C s t | jdk �S )zIs development.r )r% r r' r# r# r$ �_is_dev� r* zVersion._is_devc C r& )zIs post.r )r% r r' r# r# r$ �_is_post� r* zVersion._is_postc C s t | j S )z Get development status string.)� DEV_STATUSr r' r# r# r$ �_get_dev_status� s zVersion._get_dev_statusc C s� | j dkr| j� d| j� �}n | j� d| j� d| j � �}| �� r,|t| j � | j� �7 }| �� r8|d| j� �7 }| � � rD|d| j � �7 }|S )z Get the canonical output string.r �.z.postr ) r r r r) r r r r, r r+ r )r( �verr# r# r$ �_get_canonical� s zVersion._get_canonical)r r r r )r r r r r r r r r r r r r r r r )r r% )r r ) �__name__� __module__� __qualname__�__doc__r r) r+ r, r. r1 � __classcell__r# r# r!
