Do you think we are missing an alternative of cabal-file or a related project?
cabal-file is a library on top of the hackage-security library for accessing cabal files and versions, and also a small tool for getting and comparing .cabal files.
Since it accesses package and .cabal file data directly from the local Hackage repo cache index tar archive under ~/.cabal/ it is quite fast.
List all Hackage packages:
$ cblfile list | grep ghcide ghcide
List versions of a package:
$ cblfile list pandoc 0.4 : : 18.104.22.168
Diff .cabal files of package versions
$ cblfile diff pandoc 2.8 22.214.171.124 --- pandoc-2.8.cabal 2020-05-24 19:47:58.487921450 +0800 +++ pandoc-126.96.36.199.cabal 2020-05-24 19:47:58.487921450 +0800 @@ -1,10 +1,10 @@ name: pandoc -version: 2.8 +version: 188.8.131.52 cabal-version: 2.0 : :
Latest version of a package:
$ cblfile latest extra 1.7.1
Timestamp for the latest .cabal file (or for a specific version):
$ cblfile date dhall 2020-05-19 02:18:01 UTC
Save a .cabal file (latest or specific version)
$ cblfile get purescript $ ls purescript.cabal purescript.cabal
Check package source metadata:
$ cblfile metadata tls-1.5.4 Size: 150171 SHA256 Hash "ce42bfa581a50f62776581da4b86408ebb1a51bc6cb2f95ad0a2ac7caa19a437"
cblfile depends outputs quite verbose package dependency lists.
For library documentation see the Hackage.Index documentation.
For example usage see
I originally wrote the
depends command for displaying dependency information
about packages in a more friendly way.
Later, since hdiff is no longer actively updated,
and I particularly want it for comparing .cabal file versions,
I decided to create the
Realising I could pull .cabal files direct from the cabal index cache,
the rest of cabal-file flowed on from there.
If you want full diffs of Hackage sources you can try out cabal-diff from cabal-extras.
