HMON is a protocol supported by version 19.0 and later of Dyalog APL. It allows the writing of applications which monitor the state of one or more running APL interpreters.
The docs folder contains documentation:
docs/Protocol.md Describes the protocol supported by the interpreter.
docs/UsageGuide.md Describes the sample application and provides guidelines for writing your own client.
The source code for the demonstration client can be found here. See the Usage Guide for more instructions on how to load and run this code..
Issues with HMON can be reported as GitHub issues or via the Dyalog Helpdesk at support@dyalog.com.
