Install packs

Implement cpackget install command.

It consists of:

• downloading/copying a pack version to <cmsis-pack-root>/.Download

• extract files into <cmsis-pack-root>/<vendor>/<packname>/<version>/

• save a copy of pdsc file as versioned pdsc file in .Download (<vendor>.<packagename>.<version>.pdsc)

NOTES

1. If a pack (<vendor>.<packagename>) is not listed in <cmsis-pack-root>/.Web/index.pidx it is treated as “local pack”. A copy of the pdsc file is stored in <cmsis-pack-root>/.Local

2. <package> can be a versioned CMSIS-Pack file:

   1. from the file-system (file://localhost/.../)

   2. from the web (URL: https://.../)

3. <pdsc> is a CMSIS-Pack description file inside of an ‘extracted’ CMSIS-Pack from the file-system.

   1. In this case the pack content is not stored within the <cmsis-pack-root> itself but a reference to the pdsc file is stored in <cmsis-pack-root>/.Local/local_repository.pidx

   2. The file complies to the PIDX schema <pdsc vendor="...” name="..." url=file://localhost/.../ version="..."/>

4. The installation shall be gated by the license specified by the PDSC file

5. The installation should be optionally gated by a validation of a digital signature (to be defined in a new epic)
