Use StrictData

[srid]

Repro for kowainik/stan#392

Run this command to get the path to the stan report,

echo $(nix build --print-out-paths)/stan.html

Despite using StrictData in both the cabal file and the module (Main.hs), notice that stan will fail to recoginze it:

From nix log /nix/store/0j3nf2vqzb64zcv94xz32hki506nfz3q-haskell-template-0.1.0.0.drv:

It could be because stan isn’t aware that we have added StrictData in the .cabal file.

Even after providing the .cabal file, stan fails to recognize StrictData.

Edit: Ah, the problem seems to be Extensions from .cabal: Unable to extract extensions

Yes, you can see the "Unable to extract extensions" error in the original screenshot I posted above. However, this still doesn't explain why it can't recoginze the explicit language pragma I added in Main.hs.

Only seems to happen when we are not running stan from the project root.

Both adding StrictData to .cabal and as an explicit language pragma in Main.hs are detected after using the fix from srid/haskell-flake#386.

Run to get stan report with the above PR: echo $(nix build github:srid/haskell-template/stan-strict-data --override-input haskell-flake github:shivaraj-bh/haskell-flake/stan --print-out-paths)/stan.html

Perfect!
