pj_marketplace

Extension marketplace for PlotJuggler — handles registry fetching, package downloads, and extension lifecycle management.

Dependencies

All dependencies are managed by Conan:

Qt6 (Core, Widgets, Network, Test)
libarchive
GTest

Build

The module is built as part of the PJ4 tree from the repo root, which runs Conan (root conanfile.txt) + CMake and compiles pj_marketplace via add_subdirectory(pj_marketplace):

bash

# From the repo root
./build.sh

Build output:

build/libpj_marketplace.a — static library
build/pj_marketplace_app — standalone executable
build/tests/ — test executables

Only the in-tree build (./build.sh from the repo root) is supported. The CMakeLists has a standalone-root guard, but it does not build the full module on its own: pj_marketplace_ui PUBLIC-links the pj_widgets target and marketplace_window.ui uses the custom widget PJ::ComboBox from pj_widgets/ComboBox.h, neither of which the standalone CMake root provides (only the root add_subdirectory(pj_widgets) does). A bare cmake -S pj_marketplace -B build configures the core library and tests but cannot link pj_marketplace_ui / pj_marketplace_app.

Run Tests

bash

cd build && ctest --output-on-failure
