interpretProcess :: forall resource err i o r. Member (Scoped resource (SystemProcess !! err)) r => Members [ProcessOutput 'Stdout o, ProcessOutput 'Stderr o, ProcessInput i, Resource, Race, Async, Embed IO] r => ProcessOptions -> InterpreterFor (Scoped () (Process i o) !! ProcessError) r Source #

Interpret Process with a system process resource whose file descriptors are connected to three TBMQueues, deferring decoding of stdout and stderr to the interpreters of two ProcessOutput effects.

interpretProcessByteString :: forall resource err r. Members [Scoped resource (SystemProcess !! err), Resource, Race, Async, Embed IO] r => ProcessOptions -> InterpreterFor (Scoped () (Process ByteString ByteString) !! ProcessError) r Source #

Interpret Process with a system process resource whose stdin/stdout are connected to two TBMQueues, producing ByteStrings. Silently discards stderr.

interpretProcessByteStringLines :: forall resource err r. Members [Scoped resource (SystemProcess !! err), Resource, Race, Async, Embed IO] r => ProcessOptions -> InterpreterFor (Scoped () (Process ByteString ByteString) !! ProcessError) r Source #

Interpret Process with a system process resource whose stdin/stdout are connected to two TBMQueues, producing chunks of lines of ByteStrings. Silently discards stderr.

interpretProcessText :: forall resource err r. Members [Scoped resource (SystemProcess !! err), Resource, Race, Async, Embed IO] r => ProcessOptions -> InterpreterFor (Scoped () (Process Text Text) !! ProcessError) r Source #

Interpret Process with a system process resource whose stdin/stdout are connected to two TBMQueues, producing Texts. Silently discards stderr.

interpretProcessTextLines :: forall resource err r. Members [Scoped resource (SystemProcess !! err), Resource, Race, Async, Embed IO] r => ProcessOptions -> InterpreterFor (Scoped () (Process Text Text) !! ProcessError) r Source #

Interpret Process with a system process resource whose stdin/stdout are connected to two TBMQueues, producing chunks of lines of Texts. Silently discards stderr.

interpretInputOutputProcess :: forall i o r. Member (Process i o) r => InterpretersFor [Input o, Output i] r Source #

Reinterpret Input and Output as Process.

interpretInputHandleBuffered :: Member (Embed IO) r => Handle -> InterpreterFor (Input ByteString !! ProcessError) r Source #

Interpret 'Input ByteString' by polling a Handle and stopping with ProcessError when it fails.

interpretInputHandle :: Member (Embed IO) r => Handle -> InterpreterFor (Input ByteString !! ProcessError) r Source #

Interpret 'Input ByteString' by polling a Handle and stopping with ProcessError when it fails. This variant deactivates buffering for the Handle.

interpretOutputHandleBuffered :: Member (Embed IO) r => Handle -> InterpreterFor (Output ByteString !! ProcessError) r Source #

Interpret 'Output ByteString' by writing to a Handle and stopping with ProcessError when it fails.

interpretOutputHandle :: Member (Embed IO) r => Handle -> InterpreterFor (Output ByteString !! ProcessError) r Source #

Interpret 'Output ByteString' by writing to a Handle and stopping with ProcessError when it fails. This variant deactivates buffering for the Handle.

interpretProcessIO :: forall i o ie oe r. Members [Input ByteString !! ie, Output ByteString !! oe] r => Members [ProcessInput i, ProcessOutput 'Stdout o, Resource, Race, Async, Embed IO] r => ProcessOptions -> InterpreterFor (Process i o !! ProcessError) r Source #

Interpret Process in terms of Input and Output. Since the i and o parameters correspond to the abstraction of stdio fds of an external system process, i is written by Output and o is read from Input. This is useful to abstract the current process's stdio as an external process, with input and output swapped.

interpretProcessHandles :: forall i o r. Members [ProcessInput i, ProcessOutput 'Stdout o, Resource, Race, Async, Embed IO] r => ProcessOptions -> Handle -> Handle -> InterpreterFor (Process i o !! ProcessError) r Source #

Interpret Process in terms of two Handles. This is useful to abstract the current process's stdio as an external process, with input and output swapped. The first Handle argument corresponds to the o parameter, the second one to i, despite the first one usually being the current process's stdin. This is due to Process abstracting an external process to whose stdin would be written, while the current one's is read.

interpretProcessCurrent :: Members [ProcessInput i, ProcessOutput 'Stdout o, Resource, Race, Async, Embed IO] r => ProcessOptions -> InterpreterFor (Process i o !! ProcessError) r Source #

Interpret Process using the current process's stdin and stdout. This mirrors the usual abstraction of an external process, to whose stdin would be written, while the current one's is read.
