Concepts

The quick start shows how to use plesty-lib. This chapter explains how it works underneath: how data moves during a measurement, how an instrument is checked before use, how the library is divided, and why it is built this way. You do not need it to write a module, but it answers the questions that come up when something behaves unexpectedly, or when you want to change plesty-lib itself.

Page	Explains
Where a Measurement’s Data Goes	the run folder, how large files reach it, and how a running measurement is paused or stopped
Preflight: is the instrument actually there?	the check before a measurement, from the connection up to the experiment
Packages and Layers	the parts of plesty-lib and which may use which
Interface Contracts	what each part promises to the code built on it
Design Decisions	why plesty-lib is built this way, and what each choice costs
Dependencies	the packages plesty-lib requires, and the rules for adding one
