TODO:

  • fix the tests
  • default to not splitting into words
  • delete the now-unused homemade argument-parsing library
  • delete the now-unused Spec types
  • implement the missing modes (except Shell)
  • update the documentation
  • make it clearer what the default mode is

The tests are now passing but likely still missing some mode handling.

Hmm, hawk '2+2' also fails locally for me :-(

But hawk -e '2+2' works.

Looks like the default behaviour when no flags are specified switched from printing a value to splitting lines into words and applying a transformation on each of them:

> $ echo "hello world" | hawk 'reverse'
world hello

processSpec (src/System/Console/Hawk.hs) still needs to handle each HawkMode.
