hsmv's Introduction

hsmv

Program to rename Haskell modules.

Haskell module rename

Usage: hsmv [--version] [--help] --from ARG --to ARG --from-path ARG
            --to-path ARG MODULEPATH [--dry-run] [--no-auto-qualify]
  This program renames modules.

Available options:
  --version                Show version
  --help                   Show this help text
  --from ARG               The original module name
  --to ARG                 The target module name
  --from-path ARG          The original module path
  --to-path ARG            The target module path
  MODULEPATH               Filepath for a module
  --dry-run                Don't make changes, just print what would be done.
  --no-auto-qualify        Disable auto-qualify

Pipe in all the files in your project. If I were to do it on this project, it would be:

$ find src app test -name '*.hs' | \
  xargs hsmv --from Hsmv --to Hsmv2 \
             --from-path src/Hsmv.hs --to-path src/Hsmv2.hs

You can use --dry-run to see what would be changed in all the files before running it.

By default, modules are aliased with the name of their old name. This means the module will still compile despite the rename. If they're already qualified, the qualification is untouched. Disable this feature via --no-auto-qualify.

Scope and limitations

Renames headers module X ...
Renames imports import .. X
Does not rename qualified expressions X.sort, for example. May in the future.

Note:

Use one of these to implement anchored replace:

findFirstPrefix :: RE' a -> Text -> Maybe (a, Text)
findLongestPrefix :: RE' a -> Text -> Maybe (a, Text)
findShortestPrefix :: RE' a -> Text -> Maybe (a, Text)
