Welcome to the House of Weavers...

The Weaver v3.0.2

The actual release version is actually now 3.1 — I'll update the page to match someday... This is the program that forms the core of the two suites below. Follow the link for details.


The MusicWeaver

Build functions to perform multiple transformations on MIDI streams in real time... Enhance live performances...

The StreamWeaver

"Visual Pipes" for shell commands... with windowed input and output... (No relation to — more recent — commercial progams of the same name!)


The Weaver suites are 'Construction Kits' that let you build complex functions out of simple elements, by placing them in a diagram and connecting them together. Simple mouse drag & drop operations are all that's needed to construct the diagram.

Each suite of modules is targetted toward a specific type of data --- MIDI in the case of the MusicWeaver, generic posix data streams for the StreamWeaver --- but they all use the same diagram-manager program. Any kind of sequential data that needs to be processed in a series of steps can in priciple be handled by the scheme --- provided suitable modules for the purpose exist. All data is tagged as to its nature, so that modules will only concern themselves with data that they know about; different kinds can thus be freely mixed, interacting only when --- and if --- necessary.

Follow the links above for more information on the individual packages and for download links (PPC and Intel).

matt

— a regular-expression matching program with a difference.

matt is a simple, old-fashioned, command-line driven program, but I believe it is fairly unique in relation to commonly available tools, such as grep and awk, with somewhat similar functions. Like them, it locates segments of a text by matching with regular expressions. Unlike them, it is not 'line-bound': an expression 'locates' exactly the text that it matches, rather than the line that contains it. The matched segment may be part of a line, or extend over several lines.

That seemingly minor difference in strategy means that matt can handle tasks that are difficult or impossible with the other programs. It can pull entire paragraphs that match some desired criterion out of a text, locate elements within an HTML or XML file, and so on. In fact it can even look for byte sequences in binary files (see below).

An "output template" may be specified that controls exactly what is output when a match is found.. It can reorder segments of the match, or insert other text determined by the content of the match. If desired, the unmatched portions of the input can be output unchanged, interleaved with the (transformed) matches, so alterations can be made where desired throughout a file.

One other feature that may be important is that matt is (by default) UTF-8-aware. Both the regular expressions and searched text may contain UTF-8 byte sequences, and will be handled properly. Alternatively it has an "8-bit clean" mode, in which it scans a file as full 8-bit bytes; in this way it can even scan binary files using regular expressions containing arbitrary bytes of interest.


matt was available first for BeOS, because that's where I developed it, but it's straightforward posix code and also runs on Linux etc. I've packaged the source with a fairly general Makefile. It's available for download here, where you can also read a little more detail.

This release (v1.4 — January 2006) improves handling of unmatched text after it has been scanned; previously it would accumulate all text until it hit a match; now it disposes of buffers once they are done with.

The v 1.3 release (April 2005) finally provided a fully working '-8' option, that properly processes binary files, with regular expressions that can contain any 8-bit byte. It also added a couple of new conditional template elements (see docs).

PsiONtrack

This package allows you to mount your Psion Series 5 (5mx or Revo) as a BeOS file system, and access the Psion from the Tracker. (Based on 'PalmBeach' by Michael Pieper for the Series 3 machines.) Intel only at the moment.

The current version has added facilities for copying Contacts data (5mx/Revo) to BeOS Person files. To go in the other direction, use the VCard-People package below.


VCard<—>People

The VCard format is an open standard used for storing and interchanging personal ("Business Card") data by applications on many platforms. The two small programs in this packaga will convert between this format and BeOS 'Person' files, making it possible to share contact data between BeOS and other platforms.

Packages are available for both x86 and PPC. They are identical except for the executables themselves. Source is included.


NIMROD

Now well over fifty years ago, in May 1951, the very first 'Computer Game' made its appearance, at the Exhibition of Science (part of the Festival of Britain) in South Kensington, London. The NIMROD Computer played the game of NIM against visitors to the exhibition. This simulation for the BeOS attempts to recreate the experience of playing against that old machine. No high-speed game action here, and it's mostly in glorious black-and-white (!) but it illustrates a bit of history that probably should not be forgotten.

(The link above describes the original machine in more detail.)


xicon

A freely distributable [and very useful!] little utility that lets you give shell scripts icons that will accept dropped files as arguments, open Terminal windows, and so on...

Follow the link for more information and downloading. (PPC & Intel)


ImageMapper

Another little tool. This one lets you create Image maps for your Web pages. Follow the link for more information and downloading. (PPC & Intel)


Other BeOS programs on this site

photopc

This one is not mine at all -- I simply did the port to BeOS. It is a marvellously flexible (though command-line driven) program for downloading images from, and generally managing, your digital (still) camera. It's Intel only at the moment, I'm afraid.


Antiword

Here is another quick port. 'Antiword' is a program by Adri van Os that converts Microsoft Word files to either Postscript or plain text (and now XML and PDF). This is now version 0.37 of the program (2006/01/31).

The program itself compiles directly from the author's sources. The source is therefore not included in the package, as it is readily available from the author's own site.

An 'Install' script icon is provided, for quick setup. For convenience to those who have xicon, some scripts have been included that will let you convert or view Word files with drag-and-drop.

spiff

Once in a long while, one comes across a real lost gem. I recently had a need for a program like this and, after some fairly heavy googling, I found spiff. Its purpose is to compare word (and numeric value) sequences without regard to whitespace or newlines. It therefore works where diff doesn't — where text has been reformatted, for instance. It will even compare floating-point values with a tolerance, so you can look for significant differences in two data files.

Written over 15 years ago by a guy at BellCore, it compiled under BeOS with only a couple of trivial language updates. I haven't moved it over to my ol' BeBox yet, but the source is in the package so you can build it yourself for your machine (it also compiles on Linux...).
