EPICS IOC record search and meta information tool

EPICS IOC record search and meta information tool.

Spiritual successor of recordwhat.

What?

Lark grammar-based parsers which parse any of the following into easy-to-use Python dataclasses:

• EPICS access security files (.acf)

• EPICS autosave save files (.sav)

• EPICS V3 database files

• EPICS V4 database files

• EPICS msi-style template/substitutions files (.template/.substitutions)

• EPICS gateway configuration (.pvlist)

• EPICS sequencer state notation language programs (.st)

• EPICS StreamDevice protocols (.proto)

All of the above can be easily serialized to JSON for interoperability.

Pseudo-IOC shell interpreter:

• Reads st.cmd files as if it were an IOC

• Loads and lints record files (and other supported formats above)

• Builds inter- and intra- IOC PV relationship graphs

• Stores context information about where each record/field/etc came from

API server

• IOC finder (LCLS IOC manager, list of files, or external script)

• Provides access to all parsed information above

• Preliminary asyncio-based client to talk with the server

Frontend

• User-friendly vue.js v3 frontend that communicates with API server

• Interfaces for:

  • Searching for records

  • Record relationships (processing and links, cross-IOC links)

  • IOC information

  • Gateway configuration overview

  • Duplicate records

  • Optional plugins

Plugins

• happi devices

• Simple LDAP search (LCLS hosts, “netconfig”)

• LCLS-specific epicsArch / logbook DAQ PVs

• TwinCAT PLC source code (pytmc)

Command-line tools

• whatrecord lint - lint a database

• whatrecord parse - parse supported formats

• whatrecord server - start the API server
