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.
