This is SIM, Software and text similarity tester, most recent revision
(2.19, 20050220)
by Dick Grune, Vrije Universiteit, Amsterdam, the Netherlands (dick@cs.vu.nl).
SIM tests lexical similarity in texts in C, Java, Pascal, Modula-2, Lisp,
Miranda and natural language. It can be used
- to detect potentially duplicated code fragments in large software projects,
- to detect plagiarism in software and text-based projects, educational and
otherwise.
The program is fast:
the UNIX version on a Sun ULTRA does about 50000 tokens/sec,
the DOS version on a Pentium 166 does about 25000 tokens/sec.
SIM is available for UNIX (in source code) and MSDOS (32-bit executables).
UNIX:
To obtain the files, do:
sh sim_2_21.shar
This unpacks the sources, the Makefile, sim.1 and READ_ME.
For installation notes and other info then see READ_ME.
MSDOS:
To obtain the files, do:
[pk]unzip SIM_2_21.zip
This unpacks the executables, SIM.DOC and READ.ME.
For other info then see READ.ME.
Changes from Release 2.19:
Various changes necessitated by Linux flex being different
Changes from Release 2.16:
Various updates and adjustments in the code and the installation
procedure.
Changes from Release 2.13:
Percentage reporting feature added.
Changes from Release 2.12:
Miranda checker added.
Changes from Release 2.9:
Java checker added.
The C checker 'sim' was renamed to 'sim_c', for uniformity.
Converted the sources to ANSI C.
All versions now report non_ASCI characters in the input.
Changes from Release 2.8:
DOS versions can now compare very large files (>400000 tokens)
Changes from Release 1.21, as posted in comp.sources.unix (1987):
Ported to MSDOS
Significant speed improvements
New options: -e, -S and / , to compare files group-wise
New option: -F , to require function names to match exactly
Lisp version added
Miscellaneous improvements
