brew install specific version of ack

[rrevi]

Hello,

In the following Formula, using the brew install command, how do I install a specific version? Where I would invoke the else statement in line 49 (meaning not to install HEAD but instead a specific version of ack).

Thanks in advance

Homebrew does not allow specifying arbitrary versions to install. You could use brew extract to copy an older version of a formula but there is no telling if that works.

Thanks @SMillerDev

One small follow up question, so if brew doesn't allow/support specifying arbitrary versions to install, then what or how do you invoke the else statement in line 49 if the current version of the ack Formula? It seems to me that it is there to support installs of versions other than HEAD, no?

brew install ack will use that. brew install --HEAD ack will use the first part
