README for pd external package 'pdstring'
Last updated for pdstring v0.02
DESCRIPTION
The 'pdstring' package contains objects for converting to and from
(ASCII)-strings, represented as lists of floats.
INSTALLATION
Issue the following commands to the shell:
cd PACKAGE-XX.YY (or wherever you extracted the distribution)
./configure
make
make install
BUILD OPTIONS
The 'configure' script supports the following options, among others:
* --enable-debug , --disable-debug
Whether to enable verbose debugging messages. Default=no.
ACKNOWLEDGEMENTS
PD by Miller Puckette and others.
Ideas, black magic, and other nuggets of information drawn from code by
Guenter Geiger, Larry Troxler, and iohannes m zmoelnig.
KNOWN BUGS
Memory Usage
Encoding each byte of a string as its own float is shamefully wasteful:
it uses only 1 byte out of at least 3 which could be losslessly used
given ANSI/IEEE Std 754-1985 floats, not to mention the remaining
byte(s) (usually 1) of the float itself or the (usually 4) bytes used
for the a_type flag. Unfortunately, Pd trims some floating point
precision in message boxes and in float atoms, so a truly lossless float
encoding for Pd would only be possible using 2 bytes per float (wasting
1/2 the space of the float itself), and (to me), the memory saving such
an encoding would provide is just not worth the lack of transparency and
additional workload it would involve (but contact me if you want the
code anyways).
