Additional context

An issue is already open in homebrew repo https://github.com/Homebrew/homebrew-core/issues/42304

You should ask the macvim developers if the change was intentional. If it was you can make the change in homebrew using this guide: https://docs.brew.sh/How-To-Open-a-Homebrew-Pull-Request

Thanks for your report, @vaga

MacVim build 157 was a pre-release for a while and maintainers of the formula in Homebrew didn't release that.

The best way it to contact with maintainers of formula as it is supported by other people.

I do wonder if the pre-release status broke something. I random into some Travis issues that I had to resolve and released a new binary to fix the issue, so maybe Homebrew caught the old one. I can post on the other issue in Homebrew.

@ychin

There's a live checking for unupgraded packages in package distributing systems like Homebrew and MacPort. This live check is based on regex and if version looks like a next major version, people tend to upgrade a package version semi-automatically. I've tried to catch the "pre-release" status for some app and regex became very complex to avoid such situations.

This is now a problem for me on catalina. not quite sure what to do

[ychin]

I will push out a new version soon to address this (seems easier than the alternative). Apologies for the previous pre-release status as I ran into some build issues. It should have been smoothed out now.

[SMillerDev]

The alternative is just changing the checksum and refering to this thread in the pull request. Which seems a lot easier.

Hey @ychin totally no rush, just curious when you planned to do that? I tried using --HEAD and it works, but it introduces a lot of other changes to fonts that I don't want.

@ychin Could you mark beta releases something like 158-b1 or something like this to eliminate this issue in the future? Automatic verifier lists versions by regex, totally ignoring "pre-release" label

[ychin]

@9mm snapshot 159 is released now. Homebrew should be updated shortly.

[9mm]

awesome!

Just to respond to this it was a mistake of mine to have rebased while using the same tag. I intended to release it but had to make a change. In the future I would just increment the snapshot number.

Homebrew version got updated. Could you check if the problem got fixed?

[9mm]

it works!

@vaga Could you check if you're still experiencing the issue? If not, please, close the issue
