NAME

       dub - Package and build management system for D

SYNOPSIS

       dub describe [<package>] OPTIONS...

DESCRIPTION

       Prints  a JSON build description for the root package an all of their dependencies in a format similar to
       a JSON package description file. This is useful mostly for IDEs.

       All usual options that are also used for build/run/generate apply.

       When --data=VALUE is supplied, specific build settings for a project will be printed instead (by default,
       formatted for the current compiler).

       The  --data=VALUE  option  can  be  specified multiple times to retrieve several pieces of information at
       once. A comma-separated list is also acceptable (ex: --data=dflags,libs). The data will be output in  the
       same order requested on the command line.

       The accepted values for --data=VALUE are:

       main-source-file,  dflags,  lflags,  libs,  linker-files, source-files, versions, debug-versions, import-
       paths, string-import-paths, import-files, options

       The following are also accepted by --data if --data-list is used:

       target-type, target-path, target-name, working-directory, copy-files, string-import-files,  pre-generate-
       commands, post-generate-commands, pre-build-commands, post-build-commands, requirements

OPTIONS

       -b,    Specifies  the  type  of  build to perform. Note that setting the DFLAGS environment variable will
              override the build type with custom flags.  Possible names:
                debug (default), plain, release, release-debug, release-nobounds, unittest, profile, profile-gc,
              docs, ddox, cov, unittest-cov, syntax and custom types

       -c,    Builds the specified configuration. Configurations can be defined in dub.json

       --override-config=VALUE
              Uses  the  specified  configuration  for  a  certain  dependency. Can be specified multiple times.
              Format: --override-config=<dependency>/<config>

       --compiler=VALUE
              Specifies the compiler binary to use (can  be  a  path).   Arbitrary  pre-  and  suffixes  to  the
              identifiers below are recognized (e.g. ldc2 or dmd-2.063) and matched to the proper compiler type:
                dmd, gdc, ldc, gdmd, ldmd

       -a,    Force a different architecture (e.g. x86 or x86_64)

       -d,    Define the specified debug version identifier when building - can be used multiple times

       --nodeps
              Do not resolve missing dependencies before building

       --build-mode=VALUE
              Specifies the way the compiler and linker are invoked. Valid values:
                separate (default), allAtOnce, singleFile

       --single
              Treats the package name as a filename. The file must contain a package recipe comment.

       --force-remove
              Deprecated option that does nothing.

       --filter-versions
              [Experimental]  Filter  version  identifiers  and debug version identifiers to improve build cache
              efficiency.

       --import-paths
              Shortcut for --data=import-paths --data-list

       --string-import-paths
              Shortcut for --data=string-import-paths --data-list

       --data=VALUE
              Just list the values of a particular build setting, either for this package alone  or  recursively
              including  all  dependencies.  Accepts  a  comma-separated  list.  See  above for more details and
              accepted possibilities for VALUE.

       --data-list
              Output --data information in list format (line-by-line), instead  of  formatting  for  a  compiler
              command line.

       --data-0
              Output  --data information using null-delimiters, rather than spaces or newlines. Result is usable
              with, ex., xargs -0.
