-
-* 2003-12-09: re2c adopted
- - Version 0.9.1 README::
-
- Originally written by Peter Bumbulis (peter@csg.uwaterloo.ca)
- Currently maintained by Brian Young (bayoung@acm.org)
-
- The re2c distribution can be found at:
- http://www.tildeslash.org/re2c/index.html
-
- The source distribution is available from:
- http://www.tildeslash.org/re2c/re2c-0.9.1.tar.gz
-
- This distribution is a cleaned up version of the 0.5 release
- maintained by me (Brian Young). Several bugs were fixed as well
- as code cleanup for warning free compilation. It has been
- developed and tested with egcs 1.0.2 and gcc 2.7.2.3 on Linux x86.
- Peter Bumbulis' original release can be found at:
- ftp://csg.uwaterloo.ca/pub/peter/re2c.0.5.tar.gz
-
- re2c is a great tool for writing fast and flexible lexers.
- It has served many people well for many years and it deserves
- to be maintained more actively. re2c is on the order of 2-3
- times faster than a flex based scanner, and its input model
- is much more flexible.
-
- Patches and requests for features will be entertained. Areas
- of particular interest to me are porting (a Solaris and an NT
- version will be forthcoming) and wide character support. Note
- that the code is already quite portable and should be buildable
- on any platform with minor makefile changes.
-
- - Version 0.5 Peter's original ANNOUNCE and README::
-
- re2c is a tool for generating C-based recognizers from regular
- expressions. re2c-based scanners are efficient: for programming
- languages, given similar specifications, an re2c-based scanner
- is typically almost twice as fast as a flex-based scanner with
- little or no increase in size (possibly a decrease on cisc
- architectures). Indeed, re2c-based scanners are quite competitive
- with hand-crafted ones.
-
- Unlike flex, re2c does not generate complete scanners: the user
- must supply some interface code. While this code is not bulky
- (about 50-100 lines for a flex-like scanner; see the man page
- and examples in the distribution) careful coding is required for
- efficiency (and correctness). One advantage of this arrangement
- is that the generated code is not tied to any particular input
- model. For example, re2c generated code can be used to scan
- data from a null-byte terminated buffer as illustrated below.
-
- Given the following source:
-
- #define NULL ((char*) 0)
- char *scan(char *p) {
- char *q;
- #define YYCTYPE char
- #define YYCURSOR p
- #define YYLIMIT p
- #define YYMARKER q
- #define YYFILL(n)
- /*!re2c
- [0-9]+ {return YYCURSOR;}
- [\000-\377] {return NULL;}
- */
- }
-
- re2c will generate:
-
- /* Generated by re2c on Sat Apr 16 11:40:58 1994 */
- #line 1 "simple.re"
- #define NULL ((char*) 0)
- char *scan(char *p) {
- char *q;
- #define YYCTYPE char
- #define YYCURSOR p
- #define YYLIMIT p
- #define YYMARKER q
- #define YYFILL(n)
- {
- YYCTYPE yych;
- unsigned int yyaccept;
- goto yy0;
- yy1: ++YYCURSOR;
- yy0:
- if((YYLIMIT - YYCURSOR) < 2) YYFILL(2);
- yych = *YYCURSOR;
- if(yych <= '/') goto yy4;
- if(yych >= ':') goto yy4;
- yy2: yych = *++YYCURSOR;
- goto yy7;
- yy3:
- #line 10
- {return YYCURSOR;}
- yy4: yych = *++YYCURSOR;
- yy5:
- #line 11
- {return NULL;}
- yy6: ++YYCURSOR;
- if(YYLIMIT == YYCURSOR) YYFILL(1);
- yych = *YYCURSOR;
- yy7: if(yych <= '/') goto yy3;
- if(yych <= '9') goto yy6;
- goto yy3;
- }
- #line 12
-
- }
-
- Note that most compilers will perform dead-code elimination to
- remove all YYCURSOR, YYLIMIT comparisions.
-
- re2c was developed for a particular project (constructing a fast
- REXX scanner of all things!) and so while it has some rough edges,
- it should be quite usable. More information about re2c can be
- found in the (admittedly skimpy) man page; the algorithms and
- heuristics used are described in an upcoming LOPLAS article
- (included in the distribution). Probably the best way to find out
- more about re2c is to try the supplied examples. re2c is written in
- C++, and is currently being developed under Linux using gcc 2.5.8.

+ re2c is a great tool for writing fast and flexible lexers.
+ It has served many people well for many years and it deserves
+ to be maintained more actively. re2c is on the order of 2-3
+ times faster than a flex based scanner, and its input model
+ is much more flexible.
+
+ Patches and requests for features will be entertained. Areas
+ of particular interest to me are porting (a Solaris and an NT
+ version will be forthcoming) and wide character support. Note
+ that the code is already quite portable and should be buildable
+ on any platform with minor makefile changes.
+
+- Version 0.5 Peter's original ANNOUNCE and README::
+
+ re2c is a tool for generating C-based recognizers from regular
+ expressions. re2c-based scanners are efficient: for programming
+ languages, given similar specifications, an re2c-based scanner
+ is typically almost twice as fast as a flex-based scanner with
+ little or no increase in size (possibly a decrease on cisc
+ architectures). Indeed, re2c-based scanners are quite competitive
+ with hand-crafted ones.
+
+ Unlike flex, re2c does not generate complete scanners: the user
+ must supply some interface code. While this code is not bulky
+ (about 50-100 lines for a flex-like scanner; see the man page
+ and examples in the distribution) careful coding is required for
+ efficiency (and correctness). One advantage of this arrangement
+ is that the generated code is not tied to any particular input
+ model. For example, re2c generated code can be used to scan
+ data from a null-byte terminated buffer as illustrated below.
+
+ Given the following source:
+
+ #define NULL ((char*) 0)
+ char *scan(char *p) {
+ char *q;
+ #define YYCTYPE char
+ #define YYCURSOR p
+ #define YYLIMIT p
+ #define YYMARKER q
+ #define YYFILL(n)
+ /*!re2c
+ [0-9]+ {return YYCURSOR;}
+ [\000-\377] {return NULL;}
+ */
+ }
+
+ re2c will generate:
+
+ /* Generated by re2c on Sat Apr 16 11:40:58 1994 */
+ #line 1 "simple.re"
+ #define NULL ((char*) 0)
+ char *scan(char *p) {
+ char *q;
+ #define YYCTYPE char
+ #define YYCURSOR p
+ #define YYLIMIT p
+ #define YYMARKER q
+ #define YYFILL(n)
+ {
+ YYCTYPE yych;
+ unsigned int yyaccept;
+ goto yy0;
+ yy1: ++YYCURSOR;
+ yy0:
+ if((YYLIMIT - YYCURSOR) < 2) YYFILL(2);
+ yych = *YYCURSOR;
+ if(yych <= '/') goto yy4;
+ if(yych >= ':') goto yy4;
+ yy2: yych = *++YYCURSOR;
+ goto yy7;
+ yy3:
+ #line 10
+ {return YYCURSOR;}
+ yy4: yych = *++YYCURSOR;
+ yy5:
+ #line 11
+ {return NULL;}
+ yy6: ++YYCURSOR;
+ if(YYLIMIT == YYCURSOR) YYFILL(1);
+ yych = *YYCURSOR;
+ yy7: if(yych <= '/') goto yy3;
+ if(yych <= '9') goto yy6;
+ goto yy3;
+ }
+ #line 12
+
+ }
+
+ Note that most compilers will perform dead-code elimination to
+ remove all YYCURSOR, YYLIMIT comparisions.
+
+ re2c was developed for a particular project (constructing a fast
+ REXX scanner of all things!) and so while it has some rough edges,
+ it should be quite usable. More information about re2c can be
+ found in the (admittedly skimpy) man page; the algorithms and
+ heuristics used are described in an upcoming LOPLAS article
+ (included in the distribution). Probably the best way to find out
+ more about re2c is to try the supplied examples. re2c is written in
+ C++, and is currently being developed under Linux using gcc 2.5.8.

+Release 0.15
+============
+
+.. include:: ../home.rst
+
+This release started out in spring 2015 as a relatively simple code cleanup.
+
+I focused on the following problem: re2c used to repeat the whole generation process multiple times.
+Some parts of the generated program depend on the overall input statistics;
+they cannot be generated until the whole input has been processed.
+The usual way is to make stubs for all such things and fix them later.
+Instead, re2c used to process the whole input, gather statistics,
+discard the generated output and regenerate it from scratch.
+Moreover, each generation pass further duplicated certain calculations (for similar reasons).
+As a result code generation phase was repeated four times.
+
+The problem here is not inefficiency: re2c is fast enough to allow 4x overhead.
+The real problem is the complexity of code: you have to think of multiple execution layers all the time.
+Some parts of code are only executed on certain layers and affect each other.
+Simple reasoning gets really hard.
+
+So the main purpose of this release was to simplify code and make it easier to fix bugs and add new features.
+However, very soon I realized that some changes in code generation are hard to verify by hand.
+For example, even a minor rebalancing of ``if`` and ``switch`` statements
+may change the generated code significantly.
+In search of an automatic verification tool I encountered the idea of generating `skeleton <../../manual/features/skeleton/skeleton.html>`_ programs.
+
+Meanwhile I just couldn't help adding `warnings <../../manual/warnings/warnings.html>`_,
+updating build system and fixing various bugs.
+A heart-warming consequence of code simplification is that re2c now uses re2c more extensively:
+not only the main program, but also command-line options, inplace configurations
+and all kinds of escaped strings are parsed with re2c.
+l also updated the website (feel free to suggest improvements).
+
+Here is the list of all changes:

+
+
+This release fixes an error in the testing script:
+it used locale-sensitive ``sort`` utility,
+which resulted in different order of files on different platforms.
+
+Thanks to Sergei Trofimovich who reported the bug and suggested a quick fix. ``:)``
