ASOFT_PRESENTER
|
||
|
~~~~~~~~~~~~~~~
|
||
|
|
||
|
Background:
|
||
|
|
||
|
I was inspired to write this when a co-worked used an iPad for a
|
||
|
talk. The iPad is as powerful as early Cray supercomputers;
|
||
|
why waste that much processing power on a slide show?
|
||
|
|
||
|
|
||
|
In present mode:
|
||
|
Q quits
|
||
|
space or -> goes to next slide
|
||
|
<- goes to previous slide
|
||
|
|
||
|
How to Create Presentations:
|
||
|
|
||
|
./asoft_presenter DIRECTORY
|
||
|
|
||
|
Directory must contain "info" and "footer" files
|
||
|
|
||
|
In general empty lines (just linefeed) and lines starting with #
|
||
|
are ignored
|
||
|
|
||
|
info: has the slide info. First key is
|
||
|
TITLE
|
||
|
followed by title
|
||
|
AUTHOR
|
||
|
followed by author
|
||
|
EMAIL
|
||
|
followed by e-mail
|
||
|
SLIDES
|
||
|
followed by a list of files to be parsed in-order with slide info
|
||
|
END_SLIDES
|
||
|
|
||
|
footer: has info on footer
|
||
|
first line: text to be left justified
|
||
|
second line: text to be centered
|
||
|
|
||
|
slide files:
|
||
|
starting a line with %c% will center the following text
|
||
|
|
||
|
First line describes slide type
|
||
|
40COL - 40 column text
|
||
|
80COL - 80 column text (not implemented)
|
||
|
HGR - HGR with 4-lines of text
|
||
|
HGR2 - HGR with no text (note, uses page 1)
|
||
|
HGR_PLOT - plots data on HGR display
|
||
|
|
||
|
40COL - text as follows is printed to 40 column text display
|
||
|
|
||
|
HGR - first line indicates file to BLOAD.
|
||
|
following lines are text at bottom
|
||
|
|
||
|
HGR2 - first line indicated file to BLOAD
|
||
|
actually is page1 (HGR) with soft-switch thrown
|
||
|
this is because presentations get so large
|
||
|
I load them high by default into HGR page2
|
||
|
|
||
|
HGR_PLOT - loads a shape table to $1000 and uses it for
|
||
|
labeling axes
|
||
|
|
||
|
first line x and y size of data
|
||
|
next line how many tick marks on x and y axis
|
||
|
START
|
||
|
followed by x y NUM where NUM is number to
|
||
|
write at x y
|
||
|
STOP
|
||
|
number of plots
|
||
|
for each plot,
|
||
|
START
|
||
|
color of plot
|
||
|
list of data points (x y)
|
||
|
STOP
|
||
|
|
||
|
Then list of text to put in bottom 4 lines
|
||
|
|

NOTES while developing:
|
||
|
|
||
|
ARGH I've been programming in C too long can't handle things that start
|
||
|
numbering with "1" rather than "0".
|
||
|
|
||
|
AppleSoft BASIC was my first programming language; it's amazing how
|
||
|
I can still program it all these years later.
|
||
|
|
||
|
On-line documentation that can be found for shape table construction
|
||
|
is misleading at best. The original BASIC manual is best for this.
|
||
|
|
||
|
The BASIC code generated is really wasteful, especially for the
|
||
|
extravagant REM statements.
|
||
|
|
||
|
I am most proud of the code that puts the slide number at end
|
||
|
of text w/o scrolling. There's probably a better way to do it.
|
||
|
|
||
|
I should probably use page-flipping to avoid flicker, but I use
|
||
|
so much RAM it might not be doable. Probably also would
|
||
|
require assembly.
