@techreport{R-89-12, TITLE = {Experience from a Token Sequence Representation of Programs, Documents, and their Deltas}, AUTHOR = {Rober Bilos and Peter Fritzson }, YEAR = {1989}, NUMBER = {R-89-12}, INSTITUTION = ida, ADDRESS = idaaddr, ABSTRACTURL = {/publications/cgi-bin/tr-fetch.pl?r-89-12+abstr}, ABSTRACT = {A primary goal with this work has been to investigate the consequences of a token-based program and document representation. This representation lies between plain text and trees in complexity.We have found that a program or a document represented as a token sequence saves on the average 50% of memory space compared with a textual representation. Another advantage is that deltas between program versions stored in source code control systems become insensitive to changes in whitespace or formatting style. Statistics from version-handling, computation of deltas, and storage is presented in the paper.}, IDANR = {LiTH-IDA-R-89-12}, NOTE = {Also presented at the International Workshop on Software Version and Configuration Control, Grassau, FRG, January 27-29, 1988}
