From there, the text can be pasted with a +simple mouse click. autocue will then wait for a period of time +relative to the size of the text, before moving onto the next +paragraph. Successive cut buffers will be used, and then will wrap +to the beginning. + +The speed can be varied whilst the program is running - by sending +a SIGUSR1 to the process, autocue will go faster. Sending a SIGUSR2 +to the process will make it go slower. + +This program can be used to scroll a presentation, along with timing +information (a beep is sounded when the next buffer should be pasted), +and the presenter can simply paste into the presentation window. diff --git a/misc/autocue/Makefile b/misc/autocue/Makefile new file mode 100644 index 00000000000..9aa94e25c53 --- /dev/null +++ b/misc/autocue/Makefile @@ -0,0 +1,22 @@ +# $NetBSD: Makefile,v 1.1.1.1 2006/01/28 20:47:22 agc Exp $ +# + +DISTNAME= autocue-20060128 +CATEGORIES= misc +MASTER_SITES= # empty +DISTFILES= # empty + +MAINTAINER= agc@NetBSD.org +HOMEPAGE= http://www.alistaircrooks.co.uk/software.html +COMMENT= Time-based text formatter, sending output to xcb for pasting + +DEPENDS+= xcb-[0-9]*:../../x11/xcb + +do-extract: + @${CP} -R ${FILESDIR} ${WRKSRC} + +do-install: + ${INSTALL_PROGRAM} ${WRKSRC}/autocue ${PREFIX}/bin + ${INSTALL_MAN} ${WRKSRC}/autocue.1 ${PREFIX}/man/man1 + +.include "../../mk/bsd.pkg.mk" diff --git a/misc/autocue/PLIST b/misc/autocue/PLIST new file mode 100644 index 00000000000..c88f113f77f --- /dev/null +++ b/misc/autocue/PLIST @@ -0,0 +1,3 @@ +@comment $NetBSD: PLIST,v 1.1.1.1 2006/01/28 20:47:22 agc Exp $ +bin/autocue +man/man1/autocue.1 diff --git a/misc/autocue/distinfo b/misc/autocue/distinfo new file mode 100644 index 00000000000..cfed2f08e18 --- /dev/null +++ b/misc/autocue/distinfo @@ -0,0 +1,2 @@ +$NetBSD: distinfo,v 1.1.1.1 2006/01/28 20:47:22 agc Exp $ + diff --git a/misc/autocue/files/Makefile b/misc/autocue/files/Makefile new file mode 100644 index 00000000000..89693a5c9b2 --- /dev/null +++ b/misc/autocue/files/Makefile @@ -0,0 +1,8 @@ +# $NetBSD: Makefile,v 1.1.1.1 2006/01/28 20:47:22 agc Exp $ + +PROG= autocue +SRCS= autocue.c +MKMAN= no +WARNS= 4 + +.include <bsd.prog.mk> diff --git a/misc/autocue/files/autocue.1 b/misc/autocue/files/autocue.1 new file mode 100644 index 00000000000..c7849d2303a --- /dev/null +++ b/misc/autocue/files/autocue.1 @@ -0,0 +1,97 @@ +.\" $NetBSD: autocue.1,v 1.1.1.1 2006/01/28 20:47:22 agc Exp $ +.\" +.\" Copyright © 2006 Alistair Crooks.
