First piece of native EPLAN Data Portal (.edz) import. A .edz is a 7-Zip archive; QET previously had no archive handling. EdzArchive unpacks one to a temporary directory and locates the contained part.xml. The extraction backend is isolated behind extractWithSevenZipCli() so it can be replaced with a bundled decompressor later without touching callers; this M0 step shells out to a 7-Zip CLI via QProcess. Verified on three ifm sample parts (KG6000, MFH200, R1D200 — all 7z), plus the corrupt/missing-file paths. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

|
@brief Extracts an EPLAN Data Portal package (.edz) to a temporary folder.
|
|
|
|
A .edz is a 7-Zip archive holding a part definition (part.xml), an EPLAN
|
|
macro, a product image and metadata. EdzArchive unpacks it so the rest of the
|
|
import pipeline can read the (portable) part.xml.
|
|
|
|
The extraction backend sits behind a single private method so it can be
|
|
swapped without touching callers: this M0 spike shells out to a 7-Zip CLI via
|
|
QProcess; a later milestone replaces that with a bundled decompressor so no
|
|
external tool is required at runtime.
|
|
|
|
The extracted tree lives in a QTemporaryDir owned by this object and is
|
|
removed when the EdzArchive is destroyed.
