************************************************************************** * Changes in Zap between versions 1.00 and 1.10 * ************************************************************************** This file documents the changes in Zap between versions 1.00 and 1.10. It also indicates my future plans for Zap and how to contact me with suggestions. Changes 1.00-1.10 ----------------- The main change between 1.00 and 1.10 is the coloured redraw code as mentioned in the last changes file. This involved a total rewrite of all my redraw code in all 4 modes (fast chars,vdu chars,fast font,vdu font), and took quite a long time so I'm afraid I haven't managed to do many of the other things I intended to. I'm going as fast as I can. I would like to thank those who have put work into this release of Zap, especially Martin Ebourne for writing an impressive colour C mode. NB CONFIG FILE FORMAT HAS CHANGED. Redraw changes: * The fast screen redraw is now in colour and handled by a separate module called ZapRedraw. Documentation for the module is supplied. It can handle up to 32 bits per pixel colour and any font resolution. See docs directory. Side effects of this are: * Cursor foreground and background colour can be set independently. * Selection foreground and background colour can be set independently. * A choice of different cursors is given. * By default an 'empty square' cursor is left to mark the cursor position when the window looses input focus. * Different background colours can be chosen in text mode so that spaces off the end of a line are now visible. * BASIC and Code mode redraw has been altered to highlight comments and things in a different colour. * Colour C and Assembler modes are now available (see below). * All colours are user configurable and are mode dependent. New C mode: * Martin Ebourne has written a new C mode for those of you who want colouring according to syntax. See the ZapMjeHelp file in the 3rdParty directory for full details. The module includes: * Colour C mode with compilation, bracket-matching, auto-indenting, space stripping on saving. * An Acorn Assembler mode with colour. * A simple Pascal mode. * Interface to StrongHelp, with a 'find help on word at cursor' command. * Command to comment out a line in C/assembler/Pascal. * A command to adjust the selection (F6 in !Edit). NB Bryan's C mode is still there and has been updated to version 0.20. New line editor: * Olly Betts has rewritten the LineEditor module to produce a new line editor with many improvements over RKL's. See the 3rd party directory. Main improvements include: * The Wimp setting of FX 4 is used so the line editor is usable in the Wimp environment and compatible with Zap taskwindows. * TC-shell key short cuts are supported. * The line editor can be run in multiple taskwindows at once, and keeps track of the different instantiations. * Shift-TAB jumps through the possible filename completions! NB The completion doesn't add a '.' after directory names. This is because Cat won't allow them (eg "Cat wibble."). This is not a bug. The '.' should be optional in a future version. Utils module: * Paul Moore has written a utility module for Zap which offers some extra commands, including: * A command to search for the word at the current cursor position. * A command to filter the selected region through a unix like task. * Commands to move the window about using keys. * Delete word to left and right functions. NB This module is not installed by default to save memory. Simply uncomment the relevant line of the !Run file to install it. Misc changes: * The mode a file loaded into can now be based on the file path name. See the keys file variables &500+ for examples. * Swap window now brings the window to the front (see the keys file). * Big endian option added for viewing ARM6 code in big endian mode :-) * Separate key codes added for the keypad keys. (see docs.keycodes file). * The "*" operator in the keys file generalised to copy any range of keys. * Quit now works properly on RO3, restarting the shutdown procedure etc and the quit icon can now be 3D. * Template file chosen according to OS number (see !Run file). * Ctrl U now acts on the key immediately (like emacs) unless the key is one of: Delete/digit/Return. * Check datestamp is now on by default. I hope to have cured the network problems. If not then let me know! * Changed the scroll offset code so cursor is now 'centered' when overlap occurs. * Added 'confine cursor' option to keep cursor in window when scrolling. * Removed many of the standard search macros, so ()'s now match ()'s. * Added the 'C like' search commands: alert \a 7 backspace \b 8 carriage return \r 13 formfeed \f 12 horizontal tab \t 9 newline \n 10 vertical tab \v 11 * Cursor doesn't flash any more if >=4 characters long. * Ctrl U then up/down has been optimised. Now acts immediately. * The 'window width' is now handled by a single menu entry on the display menu rather than a separate one for each mode. This should work for all modes. * More sensible error messages given when a file is not loadable. * Vdu 23 scrolls now handled by the taskwindow mode - so you can now run ARMBE in a window! :-) To get the function keys (eg shift F4) type ^Q first. Try it! * ""s are turned into " when a command string is processed. Eg INSERT """hello""". * Filename completion improved in that a '.' is placed after the name if it is a directory and matches are now now case sensitive. I have major improvements planned .. * Warning is given in the minibuffer instead of an error being generated if you type in a read only buffer. * Minibuffer now goes away on a new keypress. * There is a command to copy a windows options to be the default ones, though it doesn't handle mode options yet (see the misc menu). * Taskwindow mode can now copy large selections to the current input properly. I'm afraid move (cV) doesn't work well on >80 byte of text. Use copy (cC) instead. * Can now resize task window screen while running. * Quickprint should now let form feeds (ascii 12) through. * Amu/Make throwback all goes into one file instead of opening multiple files. Docs changes: * Keycodes file created. * A modes word of workspace can now point to a block of workspace. * Added e_prevline entry point so can start screen updates at the start of a line. * Config file redesigned to be in modular form and depend on mode name rather than mode number. Misc bugs and things: * I had reports that version 1.00 did not work on Risc OS 3, where as 0.9 did. This problem is easily fixed by changing the line in the !Run file which checks for Risc Os 3 to test for 3.1, as I have done. If there are still problems then contact me immediately. * There was a bug in v1.0 that meant commands chained together with spaces round the colon eg "LEFT : RIGHT" didn't work. This has been fixed. * Fancy print still won't work with the turbodrivers (produces a page of black). I don't know why!

Proposed changes 1.10-1.20 -------------------------- Version 1.20 should be released sometime late summer, hopefully late September, depending on my workload. I'm sorry this release was delayed but it was a bit silly of me to put the release date during the second half of the university term! Things weren't helped by our network going down - apologies to anyone who's mail got lost. There are several major things I need to do: (1) Change my assembler. Editing a 850k BASIC file which is numbered in 2's because there aren't enough line numbers to number it in 3's (28,400 lines atm) is getting beyond a joke! (2) Rewrite the menu code so that each menu entry just runs a Zap command and menus are configurable. This will save space and make things more versatile. I can also merge HelpData with Commands so not duplicating everything twice. (3) Add a global 'Fold' option to turn every text-like mode into a folding mode. This probably won't be finished by the next release. Smaller things to be done: (most of them from the vsn 1 changes file :-( ) * 24 bit colour choosing instead of the menu of wimp colours used atm. All the redraw code is 24 bit now, I just have to change the colour selector. * Adjust drag for resizing minibuffer. * A CR<->LF command. * Reconnect taskwindow command. * Option to load dual edits in Read Only mode. * Compress tabs (not inside strings) command. * Adjust on title of file removes whole throwback of that file. * Function to expand tabs to spaces. * Bracket matching in basic mode. * Rawdata (type &FF1) mode to handle CRLF/LFCR line endings. * Have a option to run a list of Zap commands in the first few lines of a text file, when the file is loaded. * Indication in title when taskwindow still linked. * Search and replace confined to region. * Count option in search and replace. * Update cursor posn when GotoBox open. * Edit tabs should stop at ('s (also word plus/minus). * Configurable pixel indent from lhs of window. * Variable line number column width. * Cycle window (all window) + move next one to top commands. * Create a new window in mode/filetype via minibuffer. * Aliases! (for commands, eg LET EMACS=BASEMAP 1 type of thing). * Separate commands for swap case of a char and region? * Option to have the goto/search dboxes behaving as messydos - ie, first put the old choice in the dbox, but remove it if the user starts to type over it. * Search as you type wrapping round a la emacs. * Grungy repainting of cursor in margin borders to be improved. * Update menu shortcuts when basemap changes. * Want click on window with minibuffer open -> minibuffer. * Add key short cuts for writable dialogue boxes. * Configurable string sent to printer at end of quickprint. Suggestions/Contacting me ------------------------- If you have any suggestions concerning the main Zap module, please don't hesitate to contact me. I will almost certainly reply if you use e-mail (unless I can't get through, which has happened a couple of times). My address is in the 'Copyright' file. If your suggestions concern one of the extension modes (eg C mode) or template files, or one of the other things in the 3rdParty directory not written by me, then please write to the author concerned, and not to me (unless you have trouble getting through). All their addresses are in the 3rdParty.ReadMe file.
