NAME

dustmite - a tool for minimizing D source code.

SYNOPSIS

dustmite [OPTION]... PATH TESTER

DESCRIPTION

DustMite is a tool for minimizing D source code. Reducing C++ code also works quite well via --split *.{c,cpp,h,hpp}:d.
DustMite will parse the source code into a simple hierarchy, and attempt to
shrink it by deleting fragments iteratively, as long as the result
satisfies a user-specified condition.
PATH should be a directory containing a clean copy of the file-set to
reduce.

A file path can also be specified. NAME.EXT will be treated like NAME/NAME.EXT. TESTER should be a shell command which returns 0 for a correct reduction, and anything else otherwise.

OPTIONS

--force

Force reduction of unusual files

--reduce-only MASK Only reduce paths glob-matching MASK

(may be used multiple times)

--no-remove REGEXP Do not reduce blocks containing REGEXP

(may be used multiple times)

--strip-comments

Attempt to remove comments from source code.

--coverage DIR

Load .lst files corresponding to source files from DIR

--obfuscate

Instead of reducing, obfuscate the input by replacing words with random substitutions

--keep-length

Preserve word length when obfuscating

--split MASK:MODE

Parse and reduce files specified by MASK using the given splitter. Can be repeated. MODE must be one of: files, lines, words, d

--no-redirect

Don’t redirect stdout/stderr streams of test command.

-j[N]

Use N look-ahead processes (8 by default)

--help

Show this message

Less interesting options:

--strategy STRAT

Set strategy (careful/lookback/pingpong/indepth/inbreadth)

--dump

Dump parsed tree to DIR.dump file

--dump-html

Dump parsed tree to DIR.html file

--times

Display verbose spent time breakdown

--cache DIR

Use DIR as persistent disk cache (in addition to memory cache)

--trace

Save all attempted reductions to DIR.trace

--no-save

Disable saving in-progress results

--no-optimize

Disable tree optimization step (may be useful with --dump)
