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.
