cabal-plan
Library and utility for processing cabal's plan.json file
This package provides a library (see "Cabal.Plan") for decoding 'plan.json' files as well as the simple tool 'cabal-plan' for extracting and pretty printing the information contained in the 'plan.json' file. 'plan.json' files are generated by [cabal](https://hackage.haskell.org/package/cabal-install)'s [Nix-style local builds](http://cabal.readthedocs.io/en/latest/nix-local-build.html) and contain detailed information about the build/install plan computed by the cabal solver. == 'cabal-plan' utility The 'cabal-plan' executable (enabled via the 'exe' cabal flag) provides various operations: [info] Show basic report of dependency tree [show] Dump 'PlanJson' data-structure via 'Show' instance [tred] Show dependency tree as a graph [diff] Diff two install plans [list-bins] List all binaries [list-bin] List single binary (useful for scripting, e.g. 'cabal list-bin exe:cabal-plan') [fingerprint] Print SHA256 sums of dependencies' source tarballs and cabal files [dot] Generate graph of dependencies in '.dot' format [topo] Print plan topologically sorted [license-report] Generate license report for a component (only available when built with 'license-report' flag enabled); see<src/example/cabal-plan.md report example for cabal-plan>(<src/example/cabal-plan.html Pandoc rendered HTML>) See also ["New things in Haskell package QA" Blogpost](https://oleg.fi/gists/posts/2018-01-08-haskell-package-qa.html) for a description of the 'topo' and 'dot' operations as well as how to enable tab-completion.
