spvirit-tools
Command-line tools for EPICS PVAccess, built on the pure-Rust spvirit stack. No EPICS base installation required.
Install
pip install spvirit-tools
The tools also arrive as a dependency of the Python bindings, so
pip install spvirit puts all of them on your PATH as well.
With a Rust toolchain:
cargo install spvirit-tools
Tools
Thirteen binaries ship in the default build and the pip wheel (plus two
packet-capture tools behind the scry feature, below). They are named sp* rather than pv* so they can sit
alongside an EPICS Base installation without shadowing pvget, pvput, and
friends.
| Tool | Kind | What it does |
|---|---|---|
spget |
client | read a PV once |
spput |
client | write a PV |
spmonitor |
client | subscribe to changes |
spinfo |
client | print a PV's type structure |
splist |
client | discover servers and their PVs |
spexplore |
client, TUI | browse a server interactively |
spsearch |
client, TUI | passively watch PVA search traffic |
spsine |
client | drive a PV with a sine wave |
spget_compare |
offline | compare a captured GET exchange against spvirit's encoders |
spserver |
server | serve a .db file |
sptable |
server, TUI | an interactive spreadsheet IOC |
spdodeca |
server | serve a rotating wireframe as an image |
spgateway |
client, server | p4p-compatible PVAccess gateway |
spload is an internal load driver used by the loadtest/ harness. It is
not a user-facing tool and is not in the wheel or a default build
(--features load builds it).
Each accepts --help.
Packet capture: spvirit-scry
Two more binaries, folded in from the former spvirit-scry crate, capture
and decode live PVAccess traffic off a network interface:
| Tool | Kind | What it does |
|---|---|---|
spvirit-scry |
capture, TUI | passively capture and decode PVA traffic |
spvirit-scry_influx_collector |
capture | the same capture, exported to InfluxDB and Loki |
They are behind the optional scry feature and are not in the pip
wheel or a default build, because they link against libpcap (Linux,
libpcap-dev) or the Npcap SDK (Windows, found automatically or via
NPCAP_SDK):
cargo install spvirit-tools --features scry
Capturing needs sudo/CAP_NET_RAW on Linux or administrator rights on
Windows. The book's
spvirit-scry chapter
covers flags, source fingerprinting and the collector's configuration.
Documentation
The spvirit book covers the tools in detail, along with the client and server libraries. The root README is the shortest route in.
