Detailed Description

Main class of Plugin and Content Manager subsystem.

This class handles logistics of repository management, caching, json validation, tracking installed packages and provides some utility methods.

Repository caching is done in $KICADX_3RD_PARTY/cache directory with each repository storing it's metadata, packages and optionally resource files under it's id subdirectory.

Repository id is a prefix of sha256 of it's main url.

JSON schema file is expected to be in $KICAD_DATA/schemas directory

Installed packages are stored in <user_settings>/installed_packages.json If that file is missing PCM will try to reconstruct it from existing directory structure inside $KICADX_3RD_PARTY but package descriptions and other metadata will be lost.

Member Function Documentation

◆ CacheRepository()

bool PLUGIN_CONTENT_MANAGER::CacheRepository ( const wxString &  aRepositoryId)

Cache specified repository packages and other metadata.

This method fetches latest repository metadata, checks if there is cache on disk, compares it's last update timestamp to repository metadata and redownloads packages list if necessary. Then it checks sha256 if provided and parses the package list. Parsed packages metadata is stored in memory.

Process is repeated with resources file except it is just stored on disk and any errors at this stage are ignored.

Parameters
aRepositoryIdid of the repository to cache
Returns
true if packages metadata was cached successfully
