|

v'1.0.0' ^ v'2.0.0' -- false - 2.0.0 is not supposed to be backwards-compatible
|
|
v'2.5.1' ^ v'2.0.1' -- false - 2.5.1 is more modern than 2.0.1.

v(1,0,0):nextPatch() -- v1.0.1
|

v(1,2,3):nextMinor() -- v1.3.0 . Notice the patch resets to 0
|
|
v(1,2,3):nextMajor() -- v2.0.0 . Minor and patch are reset to 0

h1. Installation
|
|
|
|
Just copy the semver.lua file wherever you want it (for example on a lib/ folder). Then write this in any Lua file where you want to use it. You must assign the require to a global or local variable (I use a local @v@):
|
|
|
|
<pre>local v = require 'semver'</pre>
|
|
|
|
Using @v@ allows for the nice string syntax: @v'1.2.3-alpha'@.
|
|
|
|
The @package.path@ variable must be configured so that the folder in which middleclass.lua is copied is available, of course.
|
|
|
|
Please make sure that you read the license, too (for your convenience it's now included at the beginning of the semver.lua file).
|
|

|
h1. Notes about version comparison
|
|
|
|
Version comparison is done according to the specs:
|
|
|
|
Major, minor, and patch versions are always compared numerically.
|
|
|
|
Pre-release and build version precedence MUST be determined by comparing each dot-separated identifier as follows:
|
|
|
|
* Identifiers consisting of only digits are compared numerically
|
|
* Identifiers with letters or dashes are compared lexically in ASCII sort order.
|
|
* Numeric identifiers always have lower precedence than non-numeric identifiers
|
|

h1. Specs
|
|
|
|
This project uses "telescope":https://github.com/norman/telescope for its specs. If you want to run the specs, you will have to install telescope first. Then just execute the following from the root inspect folder:
|
|
|
|
<pre>
|
|
tsc -f spec/*
|
|
</pre>
|
