Feature Request: Support for comparison operators (<, >, <=, >=)

[burck1]

Would it be possible to add support for comparison operators? We're interested in using them in run conditions.

Example Runbook (Triggered Daily)

Step 1: Get Days Until Expiration

$exampleExpirationDate = Get-Date -Year 2025 -Month 12 -Day 1
$daysUntilExpiration = ($exampleExpirationDate - (Get-Date)).Days
Set-OctopusVariable -name "DaysUntilExpiration" -value $daysUntilExpiration

Step 2: Notify Every Day 30 Days Before Expiration

Step Template: Send Slack Message

Run Condition Proposed Options (no preference)

• #{Octopus.Action[Get Days Until Expiration].Output.DaysUntilExpiration < 31}
• #{Octopus.Action[Get Days Until Expiration].Output.DaysUntilExpiration | LessThan 31}
• #{calc {Octopus.Action[Get Days Until Expiration].Output.DaysUntilExpiration} < 31}

Workaround

Although there's currently no support for comparison operators, we can exploit the calc-subtraction statement and the StartsWith filter to achieve something similar by subtracting the values and checking for a negative sign "-".

Project Variables

Name	Value
DaysUntilExpiration	Octopus.Action[Get Days Until Expiration].Output.DaysUntilExpiration
DaysUntilExpirationMinus31	#{calc {DaysUntilExpiration} - 31}
WillExpireInLessThan31Days	#{DaysUntilExpirationMinus31 | StartsWith "-"}

Step 1: Get Days Until Expiration

$exampleExpirationDate = Get-Date -Year 2025 -Month 12 -Day 1
$daysUntilExpiration = ($exampleExpirationDate - (Get-Date)).Days
Set-OctopusVariable -name "DaysUntilExpiration" -value $daysUntilExpiration

Step 2: Notify Every Day 30 Days Before Expiration

Run Condition: #{WillExpireInLessThan31Days}
