     1  # Versions and Ranges
     2  
     3  Glide supports [Semantic Versions](http://semver.org), SemVer ranges, branches, tags, and commit ids as versions.
     4  
     5  ## Basic Ranges
     6  A simple range is in the form `> 1.2.3`. This tells Glide to use the latest versions that's after `1.2.3`. Glide has support for the following operators:
     7  
     8  * `=`: equal (aliased to no operator)
     9  * `!=`: not equal
    10  * `>`: greater than
    11  * `<`: less than
    12  * `>=`: greater than or equal to
    13  * `<=`: less than or equal to
    14  
    15  These can be combined. A `,` is an and operator and a `||` is an or operator. The or operators cause groups of and operators to be checked. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"`.
    16  
    17  ## Hyphen Ranges
    18  
    19  There are multiple shortcuts to handle ranges and the first is hyphens ranges. These look like:
    20  
    21  * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
    22  * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
    23  
    24  ## Wildcards In Comparisons
    25  
    26  The `x`, `X`, and `*` characters can be used as a wildcard character. This works for all comparison operators. When used on the `=` operator it falls back to the patch level comparison (see tilde below). For example,
    27  
    28  * `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
    29  * `>= 1.2.x` is equivalent to `>= 1.2.0`
    30  * `<= 2.x` is equivalent to `< 3`
    31  * `*` is equivalent to `>= 0.0.0`
    32  
    33  ## Tilde Range Comparisons (Patch)
    34  
    35  The tilde (`~`) comparison operator is for patch level ranges when a minor version is specified and major level changes when the minor number is missing. For example,
    36  
    37  * `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
    38  * `~1` is equivalent to `>= 1, < 2`
    39  * `~2.3` is equivalent to `>= 2.3, < 2.4`
    40  * `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
    41  * `~1.x` is equivalent to `>= 1, < 2`
    42  
    43  ## Caret Range Comparisons (Major)
    44  
    45  The caret (`^`) comparison operator is for major level changes. This is useful when comparisons of API versions as a major change is API breaking. For example,
    46  
    47  * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
    48  * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
    49  * `^2.3` is equivalent to `>= 2.3, < 3`
    50  * `^2.x` is equivalent to `>= 2.0.0, < 3`
