Json file content version variable value Increment by 0.0.1-CodePudding

Before I do a release of my package and tag it, I would like to update the manifest.json file version Patch value to reflect the new version of the package every time I trigger it.

Json file:

{
"version":  "0.0.0",
"timeStamp":  "2022-02-14T09:41:34 00:00",
"packages":  [
                 {
                     "name":  "data-service",
                     "type":  "docker-image",
                     "version":  "REL-1.0.5"
                 },
                 {
                     "name":  "application-service",
                     "type":  "docker-image",
                     "version":  "REL-1.0.6"
                 },
             ]
 }

So here I am trying to increment by reading the content of the Json file from Powershell:

version = (Get-Content manifest.json | ConvertFrom-Json).version

Value for the variable "version" in the Json file is 0.0.0 But My question is - how to increase the only patch value? E.g. I need to have 0.0.1 output values after transform automatically in the manifest.json file.

CodePudding user response：

Use the [version] type to parse the existing version, then increment the build number:

$data = Get-Content manifest.json | ConvertFrom-Json

# extract and increment version build number
$existingVersion = $data.version -as [version]
$nextVersion = [version]::new($existingVersion.Major, $existingVersion.Minor, $existingVersion.Build   1)

# update original data
$data.version = "$nextVersion"

# write back to disk
$data |ConvertTo-Json |Set-Content updated-manifest.json
