hask-replace

hask-replace is a command-line tool that simplifies the process of renaming Haskell modules.

The Pitch

Here's an example of how you would use hr:

bash cabal unpack dhall cd dhall-1.5.0 hr module . "Dhall.Import" "Dhall.Dependencies" cabal new-build

As you can see, it's a lot less painful than whatever witchcraft you'd have to resort to to accomplish the same thing in bash.

Installation

Script

The easiest way to install for most users is probably via a shell script, viz.

curl -LSfs https://japaric.github.io/trust/install.sh | sh -s -- --git vmchale/hask-replace

Binary releases

If the script doesn't work, you can also download prebuilt binaries. You can find binaries for various platforms on the release page.

Cargo

First, install cargo. Then:

bash $ cargo install hask-replace

You will need to use the nightly release for this to work; if in doubt run

bash rustup run nightly cargo install hask-replace

Performance

| Package | Task | Time | | ------- | ---- | ---- | | lens | Rename module | 14.77ms | | dhall | Rename Module | 7.41 ms | | haskell-src-exts | Rename Module | 30.29 ms |

Use

hr can also be used on Idris, viz.

bash git clone https://github.com/HuwCampbell/idris-lens.git cd idris-lens hr idris . Control.Lens.Maths Control.Lens.Math idris --build lens.ipkg
