NAME

       dub-dustmite - Create reduced test cases for build errors

SYNOPSIS

       dub dustmite <destination-path> OPTIONS...  [-- <application arguments...>]

DESCRIPTION

       This  command  uses  the  Dustmite  utility  to isolate the cause of build errors in a DUB
       project.

       It will create a copy of all involved packages and run dustmite on this  copy,  leaving  a
       reduced test case.

       Determining  the  desired  error  condition is done by checking the compiler/linker status
       code, as well as their  output  (stdout  and  stderr  combined).  If  --program-status  or
       --program-regex  is  given  and the generated binary is an executable, it will be executed
       and its output will also be incorporated into the final decision.

OPTIONS

       --compiler-status=VALUE
           The expected status code of the compiler run

       --compiler-regex=VALUE
           A regular expression used to match against the compiler output

       --linker-status=VALUE
           The expected status code of the linker run

       --linker-regex=VALUE
           A regular expression used to match against the linker output

       --program-status=VALUE
           The expected status code of the built executable

       --program-regex=VALUE
           A regular expression used to match against the program output

       --test-package=VALUE
           Perform a test run - usually only used internally

       --combined
           Builds multiple packages with one compiler run

       --no-redirect
           Don't redirect stdout/stderr streams of the test command

       --strategy=VALUE
           Set strategy (careful/lookback/pingpong/indepth/inbreadth)

       -j
           Set number of look-ahead processes

       --trace
           Save all attempted reductions to DIR.trace

       -b, --build=VALUE
           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,  plain, release, release-debug, release-nobounds, unittest, profile, profile-
           gc, docs, ddox, cov, cov-ctfe,  unittest-cov,  unittest-cov-ctfe,  syntax  and  custom
           types

       -c, --config=VALUE
           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, --arch=VALUE
           Force a different architecture (e.g. x86 or x86_64)

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

       --d-version=VALUE
           Define  the specified `version` identifier when building - can be used multiple times.
           Use sparingly, with great power comes  great  responsibility!  For  commonly  used  or
           combined  versions  and  versions  that  dependees  should  be  able  to  use,  create
           configurations in your package.

       --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.
