- SPHINX2.5y.txt
-
- SPHINX is a replacement for/complement to the CON: and NEWCON: devices. It is
- what I believe NEWCON should have been, although NEWCON could not be like
- SPHINX and remain compatible with CON:.
-
- In light of this, SPHINX does almost everything NEWCON does, and a lot more:
- It remembers the text that has scroll off the window, and lets you scroll back
- to it with various keystrokes and a scroll gadget.
- It allows non-blocking type-ahead.
- The line editor has an undo buffer/function.
- It has a much more usefull input line comparison algorithms than NEWCON.
- It allows a filerequester to be used to insert file paths & names.
- It will complete a partially typed word by searching back in saved text for
- words which start in the same way.
- It allows the window to iconized even while things are going on without loosing
- any output, and open the window to the full size of the screen w/ one key-
- stroke.
- It has an unlimited type-head buffer (NEWCON only allows a max of 256 bytes
- to be typed ahead).
- It allows any character to be placed in the input buffer (even null, Ctrl-@).
- It allows the window to be resized without loosing any output.
- It allows text be clipped from the SPHINX to the input line you are building,
- the clipboard (unit 0), or a file.
- It allows the contents of the clipboard (unit 0) or of a file to be inserted
- into the input line you are building, and that input can be parsed as if it
- had been typed in, or just inserted literally at the cursor.
- When the file is being inserted, the insertion does not put the rest of SPHINX
- to sleep--you can even type in commands while the insertion is taking place
- and have them be executed without the inserted text ending up in your command
- line. Also this means you can clip text from the result of the insertion
- while the insertion is taking place. So you can start an insertion from
- an "infinitly large" file/device (like AUX:), and still be able to use
- the result from various commands as soon as it is available.
- It allows any two fixed-width fonts to be used, one for writes (output), and
- the other for input.
- The input text can be drawn in a user configurable color for easy different-
- iation from written text.
- It allows any one shot IFF sound sample to be played when the BELL character
- is written and when input is requested.
- Ten often used input strings can be programed into C-F1 through C-F10.
- Windows are automatically moved, and resized, if they cannot be opened where
- the user specified due to the size of the wbscreen.
- Multiple SPHINXs share most of their data and code so that having differently
- named/configured SPHINXs doesn't cost much more memory.
- It is written completely in assembler, which ends up making its speed is about
- that of NEWCON, even through it has much more to do, under similar circum-
- stances. With various speedup tricks, and in certain special circumstances,
- SPHINX easily outruns NEWCON.
- Etc.
-
- SPHINX is an AmigaDOS device, not a shell. To use it as part of a CLI, you
- must pair it up with a shell (C='s, ASH, etc...). All SPHINX does from the
- point of view of the shell is display text to the user (Write()), return a
- line of text when read from (Read()), and set the shell's signals when
- Control-C/D/E/F are hit (and a few other minor things).
-
- SPHINX likes arp.library, but does not require it.
-
- There is a bug in the scroll gadget routine (a very old bug that I am still
- trying to track down. I think that it would better to rewrite the whole
- routine from scratch than keep looking); it happens only? when the scroll
- gadget is yanked up and down very quickly and a great deal, and even then,
- it doesn't always happen. The bug is non-fatal. All it does is position the
- cursor on the wrong line. Resizing the window causes the position of the
- cursor to be recomputed, and error is corrected.
