21. Oktober 2015

Posted on October 22, 2015 by bierpilot

Gestern war es dann doch soweit: Der 21. Oktober 2015!

Das dieses Datum aufgrund seiner Präsenz im Film Zurück in die Zukunft II solch ein krasses mediales wie auch gesellschaftliches Echo erhält, hätte ich niemals gedacht.

Natürlich konnte ich es mir nicht nehmen, zusamnen mit Andi, Dennis und Noume das ganze Triple-Spektakel ausgiebig zu zelebrieren: Vom 21.10.2015, 18 Uhr bis zum 22.10.2015 1:20 Uhr verbrachten wir einen geilen Zeitsprung in die Zukunft, und konnten alle drei Teile im Original in der Schauburg Dortmund auf Leinwand sehen.

Das Kino war sogar recht voll und einige Besucher waren mit T-Shirts oder sogar einer roten Weste und dem bunten Marty McFly Junior Cap bekleidet – richtig cool, also das war’s absolut Wert. Auch wenn ich den deutschen Synchrondialog komplett mitsprechen kann und jede Szene bis ins Detail kennen, mal ganz ehrlich: Wo wird man noch in Zukunft die Chance haben, solch einen genialen Film in einem echtem Kino zu schauen? Ich denke mal wirklich sehr selten.

Ich habe mir jedenfalls geschworen, nach diesem krassen Abend mal drei Jahre lang kein Zurück in die Zukunft mehr zu schauen… mal gucken ob ich das durchhalte ;-)…

Schönere Grammatik ;)

Posted on February 10, 2015 by bierpilot

Soo die libphorward hat jetzt auch eine schönere Grammatik für ihre BNF-Sprache. Die bereits beim self-hosting Prozess verwendete Grammatik sieht jetzt so aus:

$           /[ \t\r\n]+/                                            %ignore;

$ccl        /'.*'/                                                  %emit 1;
$string     /".*"/                                                  %emit 2;
$regex      /\/(\\.|[^\\\/])*\//                                    %emit 3;
$ident      /[A-Za-z_][A-Za-z0-9_]*/                                %emit 10;
$int        /[0-9]+/                                                %emit 11;

symbol      : ident | ccl | string | regex | inline                 %emit 20;

mod_optional: symbol '?'                                            %emit 27;
modifier    : mod_kleene | mod_positive | mod_optional | symbol ;

sequence    : sequence modifier | modifier ;

            | '%' emitflag+
            ;

nontermdef  : ident ':' alternation flags? ';'                      %emit 31;
inline      : '(' alternation ')'                                   %emit 32;

termdef     : '$' ident? ( ccl | string | regex ) flags? ';'        %emit 35;

mod_optional: symbol '?' %emit 27;

flag : "noemit" | "goal" | "ignore" | "lexem" %emit 40;

;

nontermdef : ident ':' alternation flags? ';' %emit 31;

inline : '(' alternation ')' %emit 32;

termdef : '$' ident? ( ccl | string | regex ) flags? ';' %emit 35;

gflag : "emitall" | "emitnone" | "lrec" | "rrec" %emit 41;

gflags : gflags '%' gflag+ | '%' gflag+ ;

definition : nontermdef | termdef | gflags ;

grammar : definition+ %goal;

Kann sich doch eher sehen lassen, oder? Die $-Zeichen definieren Terminaldeklarationen, es sind auch anonyme Terminaldeklarationen erlaubt, und Inline-Terminals werden jetzt über einen Pattern-Matching-Mechanismus auf existenz geprüft, so dass diese nicht extra definiert werden müssen (so wie % und ;).

Ausserdem ist die Entwicklung jetzt erstmal nach Bitbucket umgezogen, weil Sourceforge der Meinung war, meinen Benutzernamen mit dem Namen eines indischen Java-Entwicklers, mit dem ich nichts gemeinsam habe, zu verlinken, weil da irgendein blöder Bug drin ist. Ausserdem benutzen wir Bitbucket auch bei mausbrand, und bin damit bisher sehr gut gefahren :).

libphorward selfhosted!

Posted on January 26, 2015 by bierpilot

Seit Freitag ist die libphorward nun self-hosted.

Was heißt das nun konkret? Nun es hört sich ein wenig an wie autofellatio, ist aber noch viel, viel geiler! Die libphorward wurde nun um ein weiteres Modul, das Programm ppgram2c erweitert.

ppgram2c ist ein Code-Generator, welcher eine Backus-Naur-notierte Parser-Beschreibung aus einer Datei einliest und anschließend als C-Programm wieder ausgibt, also sozusagen die Funktionsaufrufe, die nötig sind, um die gewünschte Grammatik direkt in C mit dem libphorward Funktion des parser-Moduls zu definieren.

Aus der BNF-Notation für die eigene BNF-Sprache mit der Syntax:

kw_emit     = "emit" ;
kw_noemit   = "noemit" ;
kw_goal     = "goal" ;
kw_ws       = "whitespace" ;
kw_emitall  = "emitall" ;
kw_emitnone = "emitnone" ;
kw_lrec     = "lrec";
kw_rrec     = "rrec";

ws          = /[ \t\r\n]+/                                          %whitespace;

ccl         = /'.*'/                                                %emit 1;
string      = /".*"/                                                %emit 2;
regex       = /\/(\\.|[^\\\/])*\//                                  %emit 3;
ident       = /[A-Za-z_][A-Za-z0-9_]*/                              %emit 10;
int         = /[0-9]+/                                              %emit 11;

equal       = '=' ;
percent     = '%' ;
semicolon   = ';' ;

symbol      : ident | ccl | string | regex | inline                 %emit 20;

flags       : flags percent emitflag+
            | percent emitflag+
            ;

                                                                    %emit 35;

| ident equal regex flags? semicolon

%emit 35;

gflag : kw_emitall | kw_emitnone | kw_lrec | kw_rrec %emit 41;

gflags : gflags percent gflag+ | percent gflag+ ;

definition : nontermdef | termdef | gflags ;

grammar : definition+ %goal;

Ich muss gestehen, das diese Grammatik noch recht unschön definiert ist, was aber daran liegt, das noch ein paar Bugs vorliegen (equal, percent und semicolon mussten wegen Mehrfachverwendung als eigene Symbole definiert werden, sollte später so nicht sein).

Aus dieser Grammatik erzeugt ppgram2c nun folgenden C-Code (mit ein wenig awk-Hokuspokus drumherum):
