Crate ghciwatch

ghciwatch is a ghci-based file watcher and recompiler for Haskell projects, leveraging Haskell’s interpreted mode for faster reloads.

ghciwatch watches your modules for changes and reloads them in a ghci session, displaying any errors.

Note that the ghciwatch Rust library is a convenience and shouldn’t be depended on. I do not consider this to be a public/stable API and will make breaking changes here in minor version bumps. If you’d like a stable ghciwatch Rust API for some reason, let me know and we can maybe work something out.

Modules

• cli
  Command-line argument parser and argument access.

Structs

• Ghci
  A ghci session.
• GhciOpts
  Options for constructing a Ghci. This is like a lower-effort builder interface, mostly provided because Rust tragically lacks named arguments.
• GhciWriter
  A dynamically reconfigurable sink for ghci process output. Built for use in GhciOpts, but usable as a general purpose clonable AsyncWriter.
• ShutdownError
  A shutdown was requested.
• ShutdownHandle
  A handle to the shutdown system.
• ShutdownManager
  A manager for shutting down the program gracefully.
• TracingOpts
  Options for initializing the tracing logging framework. This is like a lower-effort builder interface, mostly provided because Rust tragically lacks named arguments.
• WatcherOpts
  Options for run_watcher. This is like a lower-effort builder interface, mostly provided because Rust tragically lacks named arguments.

Functions

• run_ghci
  Start the Ghci subsystem.
• run_tui
  Start the terminal event loop, reading output from the given readers.
• run_watcher
  A notify watcher which waits for file changes and sends reload events to the contained ghci session.
