@spina

scusa, mi ero perso la parte in cui spiegavi che toglievi tutti i rami non utilizzati.

Offtopic: Da questo punto di vista c'è in effetti parecchio da lavorare negli script di boot della slackware. Sono sempre invidioso di vedere la OpenSuse metterci circa 15 secondi a fare il boot (grafico) senza nessuna ottimizzazione.

ciao,
avevo fatto un'uscita un po tagliente e pignola ma effettivamente a leggere spina devo ricredermi sul "pignola".
Effettivamente i commenti restano tutti su findpkg ma ad esempio qualche ritocchino di personalizzazione agli script di boot si potrebbe fare

@Mario: sarei felicissimo di vedere il tuo script! se non leggi questo messaggio ti contatto in privato come suggeritomi.

A parte questo è venuta anche a me la voglia di fare un eliminatore di commenti da script sh
Solo che ho fatto un lexer; ve lo posto

Codice: Seleziona tutto

%%
  /*sh comment removal by Giovanni Santostefano*/
^([ \t])*"#"/"!"(.)*\n	ECHO;
^([ \t])*"$"/"#"(.)*\n	ECHO;
^([ \t])*"#"(.)*\n	{}
(.)*\n			ECHO;

%%
int yywrap(void)
{
	return 1;
}

int main(int argc, char *argv[])
{
	fprintf(stderr,"RmComment a sh script comment removal\n");
	fprintf(stderr,"by Giovanni Santostefano\n\n");
	if(argc<2)
	{
		fprintf(stderr,"Usage: rmcomment file.c");
		return;
	}
			
	yyin=fopen(argv[1],"r");
	
	if(!yyin)
	{
		fprintf(stderr, "Could not open: %s", argv[1]);
	}
	
	yylex();
	
	fclose(yyin);
}

per utilizzarlo

riguardo a questa storia dei commenti: scrivete tutto codice interpretabile con ash così gira con tutte le shell e potete cambiare di volta in volta. poi installate la korn shell come shell di sistema e fatele generare il bytecode (sì come java) e provate a vedere cosa cambia agli script di avvio... mai provato ma sarei curioso.

ash(1) non e` bash(1) che (quasi) tutti usano,
$(cmd) lo mangia, ma la [t]csh no!

Non esiste regola quale shell sia shell di sistema,
per difetto (default) e` la bash, ma non certo.

Offtopic: non ho provato tutte le shell in vita mia, però credevo che ciò che fosse scritto in ash fosse anche compatibile con le varie sh. ad ogni modo io dicevo di processare un file con ash per essere sicuro che fosse digeribile almeno da bash e korn, poi di farlo girare su una korn shell generando il bytecode, per vedere che tempi impiegava.
sinceramente non ho mai avuto problemi di lentezza per via dei commenti su pc moderni, comunque se uno è curioso può provare a vedere cosa guadagna tra bytecode e interpretazione nuda e cruda.

Non esiste regola quale shell sia shell di sistema,
per difetto (default) e` la bash, ma non certo.

spiego meglio:
1- rendi uno script ash-compliant
2- installi la korn shell, la ash e (se non ce l'hai la bash)
3- fai puntare /bin/sh a korn
4- generi il bytecode degli script di avvio e vedi che succede
5- fai puntare /bin/sh a bash
6- fai girare la stessa roba su bash e vedi che succede
7- fai puntare /bin/sh a ash
8- fai girare la stessa roba su ash e vedi che succede

preciso che _non_ intendevo sostituire in blocco la shell di default ma solo suggerire la korn come prova per chi era incuriosito dalla velocità di esecuzione degli script.

@sardylan

nella 0.4beta c'è un bug notevole... colpa mia e alcune cose da sistemare e aggiustare... appena ho finito di sistemarla la posto, altre due cose: il tool si chiama findpkg (non solo find) per rispettare lo schema slackware nel dare i nome dei pkgtools, i commenti e changelog lo lasciamo commentato nello script come fà sempre Pat anche se perdiamo 0.00030 sec .
Nella ricerca con find è meglio usare basename o sed anche se sono più lenti questo perchè il cut non và bene visto che l'opzione -f dipende da ADM_DIR...

a breve posto la 0.5beta con gli aggiustamenti

scusa, hai ragione! non ricordavo nemmeno l'esistenza della pdksh! parlavo della ksh93, che dal 2000 è rilasciata anche sotto forma di sorgenti con licenza Common Public 1.0

Per questo il mondo DEBIAN usa solo pdksh, licenza non compatible GPL!

funzia tutto tranne i colori ... almeno così sembra

è reso tutto più leggibile usando le funzioni... risolti alcuni bug e rimesso "basename" perchè è meglio visto che con un cut dipende dal valore di ADM_DIR quindi è la scelta migliore anche se si paga in termini di prestazioni.

[sardylan]

submax, i colori andavano soltanto nella versione semplice...
In quella avanzata tutto l'output passa per column e quindi si perde tutto...
Almeno così nella vecchia...
Io ho visto poco in questo periodo, ma ho delle cosettine da mettere a posto che mi hanno consigliato... Le vedo direttamente sulla nuova versione...

[submax82]

nuova versione, i colori ora funziano, inoltre ho sistemato le cose per comandi tipo:
