Specify tool dependencies using `build-tool-depends`

[ivanperez-keera]

Description

The Cabal packages in Ogma were written for an older version of Cabal. Currently, they only state a dependency on BNFC as part of a custom-setup section. However, this is sub-ideal because alex and happy are also needed, and Cabal fails to detect that requirement, and also fails to install BNFC and make it available before it tries to compile Ogma. This makes the installation instructions overly complicated (all three of those packages need to be installed by hand first), and makes Hackage report that Ogma as a whole cannot be built, resulting in the following message in the build log:

/bin/sh: 1: bnfc: not found

Type

• Management: Update Cabal packages to specify tool dependencies in a way that makes Cabal install them automatically.

Additional context

None.

Requester

• Ivan Perez.

Method to check presence of bug

Not applicable (not a bug).

Expected result

Ogma can be installed from command-line without having to manually specify that alex, happy or bnfc need to be installed first.

Desired result

Ogma can be installed from command-line without having to manually specify that alex, happy or bnfc need to be installed first.

Proposed solution

Modify Cabal packages to add BNFC:bnfc, alex:alex and happy:happy in the build-tool-depends in the libraries that use it.

Further notes

None.
