Included Modules

• Pars

Constant Summary

Clock = Raw.map do |date| Time.parse_utc(date, "%a, %d %b %Y %T") end

Part of the copyright banner, but appears on a new line so will tokenize as as standalone message.

Copyright = ((Parse.string("(c) Copyright")) + Raw).map(&.join)

Copyright message shown on connect.

DeviceError = (Parse.char('E')) >> Parse.integer.map do |e| SIS::Error.new(e.to_i) end

Error codes returned from the device.

Empty = (Parse.string("\r\n")) >> (Parse.const(nil))

GroupMute = Parse.do({(_) <= (Parse.string("GrpmD")), group <= (num(Int32)), (_) <= (Parse.char('*')), state <= BoolField, Parse.const({state, group})})

Group audio mute update / response. Level are provided in the raw device range of -1000..0.

GroupVolume = Parse.do({(_) <= (Parse.string("GrpmD")), group <= (num(Int32)), (_) <= (Parse.char('*')), (_) <= (Parse.char('-')), level <= (num(Int32)).map do |val| val * -1 end, Parse.const({level, group})})

Group volume update / response. Level are provided in the raw device range of -1000..0.

MatrixSize = Parse.do({inputs <= (num(Input)), (_) <= (Parse.char('X')), outputs <= (num(Output)), Parse.const(SIS::MatrixSize.new(inputs, outputs))})

Qik = (Parse.string("Qik")) >> (Parse.const(Ok.new))

Quick response, occurs following quick tie, or switching interaction from the device's front panel.

Raw = (((Parse.char ^ Delimiter) * (0..)) << (Delimiter * (0..1))).map(&.join)

Parse a full command response as a String. Delimiter is optional as it may have already been dropped by an upstream tokenizer.

Switch = Parse.do({input <= ((Parse.string("In")) >> (num(Input))), (_) <= (Parse.char(' ')), layer <= (word_as_enum(MatrixLayer)), Parse.const(SIS::Switch.new(input, layer))})

Broadcast or single output route update.

SwitcherInformation = Parse.do({(_) <= (Parse.char('V')), video <= MatrixSize, (_) <= (Parse.char(' ')), (_) <= (Parse.char('A')), audio <= MatrixSize, Parse.const(SIS::SwitcherInformation.new(video, audio))})

Tie = Parse.do({output <= ((Parse.string("Out")) >> (num(Output))), (_) <= (Parse.char(' ')), input <= ((Parse.string("In")) >> (num(Input))), (_) <= (Parse.char(' ')), layer <= (word_as_enum(MatrixLayer)), Parse.const(SIS::Tie.new(input, output, layer))})

Matrix signal route update.

Unsolicited = (((DeviceError | Tie) | Copyright) | Clock) | Empty

Async messages that can be expected outside of a command -> response flow.
