Project Description

Sunifdef is a command line tool for eliminating
superfluous preprocessor clutter from C and C++
source files. It is a more powerful successor to
the FreeBSD 'unifdef' tool. Sunifdef is most
useful to developers of constantly evolving
products with large code bases, where preprocessor
conditionals are used to configure the feature
sets, APIs or implementations of different
releases. In these environments, the code base
steadily accumulates #ifdef-pollution as transient
configuration options become obselete. Sunifdef
can largely automate the recurrent task of purging
redundant #if logic from the code.

3.1.3

Six bugs are fixed in this release. Five of these fixes tackle longstanding defects of sunifdef's parsing and evaluation of integer constants, a niche that has received little scrutiny since the tool branched from unifdef. This version provides robust parsing of hex, decimal, and octal numerals and arithmetic on them. However, sunifdef still evaluates all integer constants as ints and performs signed integer arithmetic upon them. This falls short of emulating the C preprocessor's arithmetic in limit cases, which is an unfixed defect.

3.1

The parser is strengthened to cope with contexts that were formerly skipped over as "obfuscated". The --obfusc option is thus redundant and is withdrawn. Six bugs are fixed. The demise of the Sourceforge compile farm means that many platforms can no longer be tested for this release.

3.0

A new --recurse option enables recursive traversal
of source directories. Users no longer need to
write driver scripts for this routinely required
capablity. A new --filter option enables selection
of input files by file-extension. A new
--keepgoing option causes processing to carry on
with subsequent input files following parse
errors. The --verbose mode now emits progress
messages. The Unix and Windows builds now accept
both sorts of line endings. Hex and octal
preprocessor constants are now parsed. Six bugs
were fixed. An extensive EXAMPLES section has been
added to the man page.

2.1.2

Two errors when compiling to the C89 standard were
fixed, as were warnings provoked by
"warn_unused_result" declarations and by building
to 64-bit.
