libxpkg Introduction

libxpkg is a set of standard libraries that help with writing xpkg package files. Using it allows convenient access to xlings runtime information and implementation of multi-version coexistence.

Main Goals

• Cross-platform and portability, improving compatibility of xpkg package files
• Provide easy-to-use interfaces for obtaining runtime information
• Interfaces related to xlings tool modules
• Some convenient functional modules for xpkg writing

Module Introduction

Module	Description
xim.libxpkg.pkginfo	Get runtime package information
xim.libxpkg.xvm	Multi-version manager API
xim.libxpkg.system	Get runtime-related system information and some system tools
xim.libxpkg.log	Log printing module
xim.libxpkg.pkgmanager	Package management module, providing installation and uninstallation dependency interfaces

Usage Example

package = {
    -- ...
}

-- Import related modules
import("xim.libxpkg.pkginfo")
import("xim.libxpkg.log")

-- ...

function install()

    -- Use API to print the version of the currently requested installation package, and its expected installation directory
    log.warn("this is a debug...")
    log.info("version: %s", pkginfo.version())
    log.info("installdir: %s", pkginfo.install_dir())

    return true
end
