It is usually claimed that lexical analysis routines are still coded by
|
||
|
|
hand, despite the widespread availability of scanner generators, for
|
||
|
|
efficiency reasons. While efficiency is a consideration, there exist
|
||
|
|
freely available scanner generators such as GLA \cite{Gray88} that can
|
||
|
|
generate scanners that are faster than most hand-coded ones. However,
|
||
|
|
most generated scanners are tailored for a particular environment, and
|
||
|
|
retargetting these scanners to other environments, if possible, is
|
||
|
|
usually complex enough to make a hand-coded scanner more appealing. In
|
||
|
|
this paper we describe RE2C, a scanner generator that not only generates
|
||
|
|
scanners which are faster (and usually smaller) than those produced by
|
||
|
|
any other scanner generator known to the authors, including GLA, but
|
||
|
|
also adapt easily to any environment.

abstract = {Writing an efficient lexical analyzer for even a simple
|
||
|
|
language is not a trivial task, and should not be done by hand. We
|
||
|
|
describe GLA, a tool that generates very efficient scanners. These
|
||
|
|
scanners do not use the conventional transition matrix, but instead
|
||
|
|
use a few 128 element vectors. Scanning time is only slightly
|
||
|
|
greater than the absolute minimum --- the time it takes to look at
|
||
|
|
each character in a file. The GLA language allows simple, concise
|
||
|
|
specification of scanners. Augmenting regular expressions with
|
||
|
|
auxiliary scanners easily handles nasty problems such as C comments
|
||
|
|
and C literal constants. We formalize the connection between token
|
||
|
|
scanning and token processing by associating a processor with
|
||
|
|
appropriate patterns. A library of canned descriptions simplifies the
|
||
|
|
specification of commonly used language pieces --- such as,
|
||
|
|
C\_IDENTIFIERS, C\_STRINGS, PASCAL\_COMMENTS, etc. Finally, carefully
|
||
|
|
tuned lexical analysis support modules are provided for error
|
||
|
|
handling, input buffering, storing identifiers in hash tables and
|
||
|
|
manipulating denotations.}
