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.
