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_kleene  : symbol '*'                                            %emit 25;
mod_positive: symbol '+'                                            %emit 26;
mod_optional: symbol '?'                                            %emit 27;
modifier    : mod_kleene | mod_positive | mod_optional | symbol ;

sequence    : sequence modifier | modifier ;
alternative : sequence |                                            %emit 30;
alternation : alternation '|' alternative | alternative ;

emit        : "emit" int?                                           %emit 42;
flag        : "noemit" | "goal" | "ignore" | "lexem"                %emit 40;
emitflag    : emit | flag ;

flags       : flags '%' emitflag+
            | '%' emitflag+
            ;

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;

$ /[ \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_kleene : symbol '*' %emit 25;

mod_positive: symbol '+' %emit 26;

mod_optional: symbol '?' %emit 27;

modifier : mod_kleene | mod_positive | mod_optional | symbol ;

sequence : sequence modifier | modifier ;

alternative : sequence | %emit 30;

alternation : alternation '|' alternative | alternative ;

emit : "emit" int? %emit 42;

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

emitflag : emit | flag ;

flags : flags '%' emitflag+

| '%' emitflag+

;

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 :).

Alter Sack!

Yo, yo yo!

Jetzt ist die Partey schon über eine Woche her, aber ich komm erst jetzt mal wieder dazu hier zu updaten. Also ich sag es nochmal ganz ausdrücklich: GEILSTE PARTY EVER! So viele tolle Gäste, eigentlich alle Menschen die ich gern habe auf einem Haufen (bis auf ein paar Ausnahmen die leider nicht da waren weil krank/verkracht/whatever) aber egal!!! Es wurden 100l Bier vernichtet, ich danke Krissy nochmal von ganzem Herzen für die geile Location und nochmal DANKE AN ALLE DIE DA WAREN!!!! 🙂

D-6235 fertig zum schminken!

Posted on January 27, 2015 by bierpilot

Soo heute war es soweit, unsere ASK 21 (D-6235) wurde um die letzten Stellen angeschliffen und dann in die Lackierkabine verlegt. Sie steht momentan dort aufgebockt auf einer Leiter und einem Bock, gehalten durch einen Holzbalken… Piddy meint “Datt hält!” und der Typ hat erfahrung, also muss er’s wohl wissen.

Piddy ist eh ein echt cooler Typ! Will zu meinem 30. kommen und die kommende Saison wollen wir ab der Rheinermark ein 300er fliegen mit Ankündigung! Und bei ihm bin ich mir sicher, das es klappt. Er fliegt die D-1245, ebenfalls eine Standard Libelle und eingefleischter Glasflügel-Fan!

Ich freu’ mich drauf!

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;

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

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):
