cab

cab

In short: write cab build instead of cabal new-build, and save six keystrokes.

The cab tool is a tiny wrapper around Haskell's [cabal]() package-building tool that rewrites the argument list so that the "new-style" project commands can be invoked without the new- prefix. Otherwise, it simply passes on all other arguments to cabal unmodified, and thus should be mostly a drop-in convenience tool to shorten some cabal invocations.

Example Usages

# cab-specific usage help
$ cab --cab-help
# standard cabal help
$ cab --help
# building a project using a new-style build
$ cab build
# configuring a project using a new-style build
$ cab configure --enable-tests
# running an application
$ cab run

Warning

As of the time of writing, cab's logic is very simplistic: it rewrites based on a set of known strings and tries to only rewrite values once. Consequently, an invocation like cab test run will rewrite to cabal new-test run, but it does mean that, in rare and unusual cases, it might apply this logic incorrectly. In the future, cab ought to properly replicate (a subset of) Cabal's command-line parsing logic, but it does not yet!
