Problem:
`vim.version.range('>=0.10'):has('0.12.0-dev')` returns false, which is
wrong per semver.
Solution:
`vim.VersionRange:has()` shouldn't have special handling for prereleases
(Why would we need it when `__eq`, `__lt`, `__le` already handle
prereleases?).

--- @brief
|
|
--- The `vim.version` module provides functions for comparing versions and ranges
|
|
--- conforming to the https://semver.org spec. Plugins, and plugin managers, can use this to check
|
|
--- available tools and dependencies on the current system.
|
|
---
|
|
--- Example:
|
|
---
|
|
--- ```lua
|
|
--- local v = vim.version.parse(vim.fn.system({'tmux', '-V'}), {strict=false})
|
|
--- if vim.version.gt(v, {3, 2, 0}) then
|
|
--- -- ...
|
|
--- end
|
|
--- ```
|
|
---
|
|
--- [vim.version()]() returns the version of the current Nvim process.
|
|
---
|
|
--- VERSION RANGE SPEC [version-range]()
|
|
---
|
|
--- A version "range spec" defines a semantic version range which can be tested against a version,
|
|
--- using |vim.version.range()|.
|
|
---
|
|
--- Supported range specs are shown in the following table.
|
|
--- Note: suffixed versions (1.2.3-rc1) are not matched.
|
|
---
|
|
--- ```
|
|
--- 1.2.3 is 1.2.3
|
|
--- =1.2.3 is 1.2.3
|
|
--- >1.2.3 greater than 1.2.3
|
|
--- <1.2.3 before 1.2.3
|
|
--- >=1.2.3 at least 1.2.3
|
|
--- ~1.2.3 is >=1.2.3 <1.3.0 "reasonably close to 1.2.3"
|
|
--- ^1.2.3 is >=1.2.3 <2.0.0 "compatible with 1.2.3"
|
|
--- ^0.2.3 is >=0.2.3 <0.3.0 (0.x.x is special)
|
|
--- ^0.0.1 is =0.0.1 (0.0.x is special)
|
|
--- ^1.2 is >=1.2.0 <2.0.0 (like ^1.2.0)
|
|
--- ~1.2 is >=1.2.0 <1.3.0 (like ~1.2.0)
|
|
--- ^1 is >=1.0.0 <2.0.0 "compatible with 1"
|
|
--- ~1 same "reasonably close to 1"
|
|
--- 1.x same
|
|
--- 1.* same
|
|
--- 1 same
|
|
--- * any version
|
|
--- x same
|
|
---
|
|
--- 1.2.3 - 2.3.4 is >=1.2.3 <=2.3.4
|
|
---
|
|
--- Partial right: missing pieces treated as x (2.3 => 2.3.x).
|
|
--- 1.2.3 - 2.3 is >=1.2.3 <2.4.0
|
|
--- 1.2.3 - 2 is >=1.2.3 <3.0.0
|
|
---
|
|
--- Partial left: missing pieces treated as 0 (1.2 => 1.2.0).
|
|
--- 1.2 - 2.3.0 is 1.2.0 - 2.3.0
