cabalvm install status

[psibi]

Right now, I want to know if cabalvm install does this stuff:

• Downloading Hackage package
• Applying patch from this repository
• Then registering the package with .ghcvm.

If this is done by cabalvm, then it has to be documented. If it doesn't, then we need to make sure that it is done.

Right now, trying cabalvm seems to install successfully (I'm not sure if it applied the patch - asking you instead):

You'll see a message if it found a patch to apply like so:

Found patch in ghcvm-hackage for [package-name]

In the above example, there was no patch for deepseq

CabalVM always downloads from Hackage. The only thing is does different is modify the contents after downloading. And you can know whether it downloaded from Hackage or re-used what was already downloaded by looking at the

Downloading [package-name]

message.

Registering a package can be found out by the

Registering [package-name]

message.

Sorry, I think my question was not well formed. I wanted to know if this has been implemented in cabalvm right now ?

Doing a grep, I was not able to find out any matching source code. In fact, searching your name in git log didn't return me anything:

sibi::casey { ~/github/cabalvm }-> git log --author="Rahul Muttineni"

[rahulmutt]

Yes, it has been implemented in cabalvm.

All the current cabalvm code is in the 1.22 branch of the rahulmutt/cabalvm repo. It's a bit confusing right now - I'll clean that up soon.

Ah, thanks. That was helpful.
