SPDXTOOL(1)                 General Commands Manual                SPDXTOOL(1)

NAME
     spdxtool - a tool for generating SPDX Lite 3.0.1 profile software bills
     of material document

SYNOPSIS
     spdxtool [options] module ...

DESCRIPTION
     spdxtool is a program which generates a JSON-LD formatted SPDX Lite 3.0.1
     software bill of materials (SBOM) for a given set of pkg-config modules.
     The output of this tool can then be translated into other SBOM formats as
     necessary.

     More documentation about SDPX 3.0.1 can be found from:
     https://spdx.github.io/spdx-spec/v3.0.1/

     The options are as follows:

     --about
             Print the version number, the Copyright notice, and the license
             of the spdxtool program to standard output and exit.  Most other
             options and all command line arguments are ignored.

     --version
             Print the version number of the spdxtool program to standard
             output and exit.  Most other options and all command line
             arguments are ignored.

     --agent-name
             Set agent name-property in /Core/Agent-class. Default is
             'Default'

     --creation-time
             Set create-property time in /Core/CreationInfo-class.  SPDX
             documentation recommends using ISO 8601-formatted time which is:
             YYYY-MM-DDThh:mm:ssZ.  Default is document creation time.  This
             takes precedence over the SOURCE_DATE_EPOCH environment variable.

     --creation-id
             Set creation ID in /Core/CreationInfoc-class.  As ID in creation
             info mainly have special format and it's default is
             '_:creationinfo_1'.

     --define-variable=varname=value
             Define varname as value.  Variables are used in query output, and
             some modules' results may change based on the presence of a
             variable definition.

ENVIRONMENT
     PKG_CONFIG_DEBUG_SPEW
             If set, print debugging messages to stderr.

     PKG_CONFIG_IGNORE_CONFLICTS
             If set, ignore Conflicts rules in modules.  Has the same effect
             as the --ignore-conflicts option in pkgconf(1)

     PKG_CONFIG_LIBDIR
             A colon-separated list of low-priority directories where pc(5)
             files are looked up.  The module search path is constructed by
             appending this list to PKG_CONFIG_PATH, which enjoys higher
             priority.  If PKG_CONFIG_LIBDIR is not defined, the default list
             compiled into the spdxtool program from the PKG_DEFAULT_PATH
             preprocessor macro is appended instead.  If PKG_CONFIG_LIBDIR is
             defined but empty, nothing is appended.

     PKG_CONFIG_MAXIMUM_TRAVERSE_DEPTH
             Impose a limit on the allowed depth in the dependency graph.

     PKG_CONFIG_PATH
             A colon-separated list of high-priority directories where pc(5)
             files are looked up.

     PKG_CONFIG_PRELOADED_FILES
             Colon-separated list of pc(5) files which are loaded before any
             other pkg-config files.  These packages are given highest
             priority over any other pc(5) files that would otherwise provide
             a given package.

     SOURCE_DATE_EPOCH
             If set, and the --creation-time option is not given, the creation
             time in /Core/CreationInfo-class is derived from this UNIX
             timestamp instead of the current time, allowing for reproducible
             SBOM generation.

EXIT STATUS
     The spdxtool utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     Generating an SBOM for the package named foo:
           $ spdxtool foo
           {
           @context: https://spdx.org/rdf/3.0.1/spdx-context.jsonld,
           @graph: [
           {
           type: Agent,
           creationInfo: _:creationinfo_1,
           spdxId: https://github.com/pkgconf/pkgconf/Agent/default,
           name: Default
           },
           {
           type: CreationInfo,
           @id: _:creationinfo_1,
           [...]
