If mph terminates, it emits +a language independent binary or text representation of the MPH +function on stdout. To generate a usable hash function, this output +should be fed to a language dependent filter, like emitc. + +e.g. + % mph <foo | emitc >hash.c + +The algorithm used by mph is probabilistic - it iterates until it +finds a MPH function. For each failed iteration, it prints a +(cryptic) reason on stderr. There is no no guarantee that mph will +terminate. In practice this is unlikely, unless the constants +specified with options -c or -m are too small (see below). diff --git a/devel/mph/Makefile b/devel/mph/Makefile new file mode 100644 index 00000000000..0baa18fa59c --- /dev/null +++ b/devel/mph/Makefile @@ -0,0 +1,19 @@ +# $NetBSD: Makefile,v 1.1.1.1 2003/12/04 08:44:58 agc Exp $ +# + +DISTNAME= mph-1.2 +CATEGORIES= devel +MASTER_SITES= http://www.ibiblio.org/pub/Linux/devel/lang/c/ + +MAINTAINER= tech-pkg@netbsd.org +#HOMEPAGE= none +COMMENT= Minimal perfect hashing functionality + +do-install: + for i in emitc mph mphm; do \ + ${INSTALL_PROGRAM} ${WRKSRC}/$$i ${PREFIX}/bin; \ + done + ${INSTALL_SCRIPT} ${WRKSRC}/mphminm ${PREFIX}/bin + ${INSTALL_DATA} ${WRKSRC}/mph.doc ${PREFIX}/share/doc + +.include "../../mk/bsd.pkg.mk" diff --git a/devel/mph/PLIST b/devel/mph/PLIST new file mode 100644 index 00000000000..250db098fa6 --- /dev/null +++ b/devel/mph/PLIST @@ -0,0 +1,6 @@ +@comment $NetBSD: PLIST,v 1.1.1.1 2003/12/04 08:44:58 agc Exp $ +bin/emitc +bin/mph +bin/mphm +bin/mphminm +share/doc/mph.doc diff --git a/devel/mph/distinfo b/devel/mph/distinfo new file mode 100644 index 00000000000..ea610ea5bec --- /dev/null +++ b/devel/mph/distinfo @@ -0,0 +1,4 @@ +$NetBSD: distinfo,v 1.1.1.1 2003/12/04 08:44:58 agc Exp $ + +SHA1 (mph-1.2.tar.gz) = 05da8d39b27d5b1d42c52d825f4d2196711a8df5 +Size (mph-1.2.tar.gz) = 22762 bytes |
