To a first approximation, it opens `ghci` and runs `:reload` whenever your source code changes, formatting the output to fit a fixed height console. Unlike other Haskell development tools, `ghcid` is intended to be _incredibly simple_. In particular, it doesn't integrate with any editors, doesn't provide access to the `ghci` it starts, doesn't depend on GHC the library and doesn't start web servers. @@ -62,6 +62,8 @@ exprN <$ -} +Expressions that read from standard input are likely to hang, given that Ghcid already uses the standard input to interact with Ghci. + ### FAQ #### This isn't as good as full IDE @@ -103,6 +105,6 @@ `ghcid ... --test Main.main --setup ":set args myargs"` -#### Why do I get "addWatch: resource exhausted (No space left on device)" on my Mac? +#### Why do I get "addWatch: resource exhausted (No space left on device)" or "openFile: resource exhausted (Too many open files)" on my Mac?
