hdev

A convenient Haskell development tool that wraps ghcid so you don't have to remember the exact commands. It automatically finds executables from hpack's package.yaml.

What problem does this solve?

I got really annoyed trying to remember exact commands specific to cabal or ghcid. This is mostly a convenience wrapper.

Benefits

• No more remembering ghcid commands - just run hdev --run and it handles the rest
• Automatically finds executables from package.yaml - no need to specify paths
• Automatically creates a ghcid output file at /tmp/<project>.ghcid

Usage

# List executables from package.yaml
hdev --list

# Run with ghcid (default)
hdev --run

# Run specific executable
hdev --run my-executable

# Lint mode
hdev --lint

# Execute with cabal run
hdev --exec-with-cmd my-executable -- --arg1 --arg2

Example

nix-shell --run "hdev --lint"
Select an executable:
1) example
2) hdev
2
Raw command: ghcid --command "cabal v2-repl exe:hdev" -o /tmp2/hdev.ghcid
...

Requirements

• GHC, cabal, ghcid, hpack

Note: Currently developed for executables only (libraries untested).
