SHORTC(1)				       General Commands Manual					    SHORTC(1)

NAME
shortc - generate short preprocessor definitions for long C identifiers
SYNOPSIS
shortc [ -symlen ] [ -p ] [ -s ] file ...
DESCRIPTION
Shortc searches for instances of long identifiers in the specified files. In its normal mode of operation shortc generates a list of preprocessor definitions that are unique in their first seven characters. The shortc output is then included into each file (or a common header file) which is processed using a flex- names version of cpp. If no files are given shortc reads from the standard input. The symlen argument may be used to change the default long identifier length from seven characters. The -s option generates a sed script instead of preprocessor definitions. The -p option causes shortc to parse preprocessor lines. These options are most useful together when flexnames support is not available from cpp.
BUGS
When using cpp, preprocessor symbols must be weeded out by hand. Otherwise they will cause (innocuous) redef- inition messages. The -p option will incorrectly parse include file names which must be removed by hand from the output. 3rd Berkeley Distribution September 5, 1988 SHORTC(1)
