Hi All
Not a question but I had a situation where I needed to organise version numbers and then pull the latest and increment it. I thought this might be of help to others who need to do the same thing.
I needed to get my version number from git. This is how you do it.
((git tag).split([environment]::newline) | sort {[version] ($_)} -descending)[0]
The above will work for any multi-line string of version numbers. PowerShell is able to sort them when you call the [Version] accelerator
I created a function to increment the version number, it's used as follows:
PS C:\bitbucket\pcs_cam> ((git tag).split([environment]::newline) | sort {[version] ($_)} -descending)[0] 0.0.21
PS C:\bitbucket\pcs_cam> ((git tag).split([environment]::newline) | sort {[version] ($_)} -descending)[0] | Increment-Version -build
0.0.22
PS C:\bitbucket\pcs_cam> ((git tag).split([environment]::newline) | sort {[version] ($_)} -descending)[0] | Increment-Version -minor
0.1.0
PS C:\bitbucket\pcs_cam> ((git tag).split([environment]::newline) | sort {[version] ($_)} -descending)[0] | Increment-Version -major
1.0.0
Here is the function:
Function Increment-Version {
<#

Hope this helps.
