Hi all, We all know and love the built-in editor, but it's good to have options. XEdit is a text editor for CMM2. The editor is written in MMBasic so is by construction open source and extensible. XEdit supports up to two windows, two buffers (files), undo and the usual complement of editor operations. Many features are still in the pipeline. See the README below for details. When taking XEdit for a spin please keep in mind that this is an early alpha release. There will be bugs. Please let me know what you think, report bugs and feel free to request features. Cheers, Ruben/Epsilon. GitHub: https://github.com/epsilon537/xedit_cmm2    xedit.zip XEdit Text Editor for Color Maximite 2 by Epsilon ------------------------------------------------- Current Version: 0.1 ChangeLog --------- 0.1: - Initial version. Description ----------- XEdit is a text editor written in MMBasic. The editor supports up to two windows (Hsplit/Vsplit or no split) and up to two buffers (files). The two buffers can be freely assigned to windows and two windows can present separate views into a single buffer. XEdit supports undo as well as the usual complement of operations: cut/copy/paste, find/replace, indent/unident selections, insert/overwrite mode, goto line. To Do's ------- - Add support for vegipete's FileDialog - Add option to display row numbers next to the rows - Add Select-All key binding - Add Macro recording and playback - Maintain backup files when saving - Syntax Highlighting - Add scroll current line to center/top/end key bindings - Restore previous context when starting editor - Add Find Next keybinding - Add resource utilization pop-up - Add optional config file with user configurable keybindings and other options Limitations ----------- - Max. 14000 lines across all buffers (including clipboard and undo buffer). - Max. 2 windows - Max. 2 buffers KeyBindings ----------- F1 = Help F2/F9 = Save File/Save File as F3 = Load File F4 = Toggle Buffer F5 = Toggle Window split F10 = Quit Ctrl-O = Toggle Active Window Ctrl-F = Find Prompt/Selection Ctrl-R = Replace Prompt/Selection Ctrl-X/Ctrl-Y/Ctrl-P = Cut/Copy/Paste Ctrl-G = Goto Line INS = Toggle Insert/Overwrite mode Home 1x/2x/3x = Go To Start of Line/Page/Buffer End 1x/2x/3x = Go To End of Line/Page/Buffer Tab/Shift-Tab = Indent/Unindent Line/Selection Shift-Navigation Key = Start/Extend Selection Ctrl-Z = Undo Alt-K = Show Key Code at prompt Alt-S = Screenshot Epsilon CMM2 projects |

Geachte heer epsilon: * Love the keybindings! * Is it possible to cut/copy from one buffer and paste into the other? That would be wonderful. * I do appreciate the syntax highlighting in the "regular" editor, and in syntax-sensitive external editors like Notepad++. Do you anticipate adding that feature? Looking forward to using your editor! - Steve (why yes, I did live in a Flemish-speaking area of Europe for a while) Johnson Live in the Future. It's Just Starting Now! |

Yes, that is supported. Yes, that's a must-have, right after the File Dialogs. Met vriendelijke groeten, Ruben/Epsilon  Epsilon CMM2 projects |

Looking good "Epsilon", You've probably got your own ideas, but you'll find BASIC for an MMBasic parser and code for (VT100 so no good for VGA output) syntax highlighting (amongst other things) here: https://github.com/thwill1000/sptools/tree/master/src/sptrans I don't think it's fast enough to use within an editor, but it hasn't been seriously optimised and perhaps its a starting point if you've got nothing better.

Hi Ruben, this is absolutely fantastic! Far more than expected. The scrolling is fast and smooth, and you've even made an undo available! I expected a few but couldn't find a bug! I'm looking forward to version 0.2!  Regards Michael PS: I suggest changing the search function so that it is case-insensitive. |

I finally found a bug: Paste is CTRL-V, not CTRL-P, as indicated in the help screen. .Edited 2020-10-30 06:36 by twofingers |

Thanks Michael. I'll fix that of course. I'll also make the search function case insensitive. Btw, I think the most frustrating issue I have right now is that I still occasionally press Ctrl-C to copy instead of Ctrl-Y... I've been using the editor to write the editor to some extent. That helped to flush out the most obvious bugs, but I'm sure there's still a long tail of more subtle and some not so subtle bugs. Cheers, Ruben/Epsilon. Epsilon CMM2 projects |

Hi Ruben, You know that you can use Ctrl-C for copy? But I don't know if it's a good idea ... BTW: I use this key assignments for Cut, Copy and Paste: CONST KEY_CTRL_INS% = 388 CONST KEY_SHFT_INS% = 1156 CONST KEY_SHFT_DEL% = 1151 CONST CUT_KEY% = KEY_CTRL_X% CONST CUT_KEY1% = KEY_SHFT_DEL% CONST COPY_KEY% = KEY_CTRL_Y% CONST COPY_KEY1% = KEY_CTRL_INS% CONST PASTE_KEY% = KEY_CTRL_V% CONST PASTE_KEY1% = KEY_SHFT_INS% CASE CUT_KEY%,CUT_KEY1% cutKeyHandler CASE COPY_KEY%,COPY_KEY1% copyKeyHandler CASE PASTE_KEY%,PASTE_KEY1% pasteKeyHandler ... and this option F12 "*\xedit"+chr$(13) to start xedit.Thank you for this masterpiece!

Thanks! I did not know that. I think I can (should?) read the user guide every week and still find new things in it. I won't change the option in the program but I will change it on my setup, just to stop myself from accidentally aborting the editor all the time. Epsilon CMM2 projects |

This is absolutely excellent. Just one question - are you using KEYDOWN because of SHIFT+Arrow Key combinations? I ask because I'd love to use this over TeraTerm but KEYDOWN rules that out. Edited 2020-11-03 05:41 by elk1984 |
||||
| epsilon Senior Member Joined: 30/07/2020 Location: BelgiumPosts: 255 |
Thank you. I am using KEYDOWN. I started out using INKEY, but INKEY just returns one byte and that wasn't good enough. I was starting to hit key combos that I couldn't capture correctly because they would overlap with other keys/combos already in use. There were a few other reasons for giving up on serial: - The cursor is a sprite, mainly because I wanted a different cursor for insert and overwrite mode. If it wasn't for overwrite mode I could have used alternating print/inverse print as a cursor. That's what Hexedit is doing btw. - The window headers are continuously updated, i.e. reprinted, to reflect current status such as row and column position. That probably won't work well over serial. - OPTION CONSOLE SCREEN is just much faster because not restricted by a baudrate, which really helps when doing full page scrolling for instances.

Thanks for the time to explain the rationale. I'm actually using TeraTerm + a VGA capture card + OBS, so seeing the sprites etc. doesn't apply in my case. I do keep a Logitech keyboard handy for emergencies but try not to keep it on my desk all the time (my brain can't track two keyboards and I invariably end up typing commands into the wrong machine  ) |

That's quite a setup you have, but I get it. The number of times I sat staring at my laptop screen wondering where all the text is going that I'm typing, only to find out that my e-mail response is now embedded in the XEdit.bas source code... I switched over to TEXT recently for the window contents. TEXT isn't affected by the serial baud rate I think, so I might be able to drop the OPTION CONSOLE SCREEN. I might also be able to reinstate INKEY instead of KEYDOWN as an option. Certain keybindings would have to change in that mode however. Maybe I can use ctrl+space to mark the start of a selection instead using shift+navigation keys. But ultimately the goal should be that the CMM2 becomes self contained enough that the PC dependency can be dropped altogether. But we'll need a lot more tools on the CMM2 before that can happen (including a BBS front-end for The Back Shed maybe?). Epsilon CMM2 projects |

Hi all, It was a struggle but I finally uploaded a new version of XEdit with limited syntax highlighting support. https://github.com/epsilon537/xedit_cmm2 This version also includes some optimizations which should make the editor overall feel more responsive. There are some critical bug fixes as well. If you already happen to be using XEdit, you really should update. Version 0.2 contained quite a few regressions, actually making it worse than 0.1. My apologies for that. I hope 0.3 will do better. I certainly gave it a lot more run-time. For further info, see Changelog below. Cheers, Ruben/Epsilon.  xedit.zip XEdit Text Editor for Color Maximite 2 by Epsilon ------------------------------------------------- Current Version: 0.3 ChangeLog --------- 0.3: - Limited MMBasic Syntax Highlighting support. - Improved vertical scrolling, line insertion and line deletion speed. - Switched to a dark solarized color scheme. If you prefer the higher contrast blue&white theme, you can still select that in the user config variables section. Or you can just roll your own of course. - Critical bug fix: potential program abort triggered by toggling window split. This bug was introduced in 0.2. - Critical bug fix: wrap-around search without hit can leave editor in inconsistent state, resulting in unpredictable behavior. - Fixed bug in replace function turning parts of replaced lines into upper case. This bug was introduced in 0.2. - Macro recording fix: new macro should overwrite existing macro, not append to it. This bug was introduced in 0.2. - Added DISABLE_CONFIRMATION prompt option. Default: 0. - Fixed a bug where last lines of a buffer would show up duplicate after deleting a selection. - Made sure that search matches are always shown fully on screen. - Increased undo depth from 16 to 32 entries. - Split view into a single buffer will now as much as possible maintain view in one window (instead of scrolling) when lines are added or removed in other window. - Now allowing replace-with-nothing. ... Description ----------- XEdit is a text editor written in MMBasic. The editor supports up to two windows (Hsplit/Vsplit or no split) and up to two buffers (files). The two buffers can be freely assigned to windows and two windows can present separate views into a single buffer. XEdit supports undo, macro recording, MMBasic syntax highlighting as well as the usual complement of editor operations: cut/copy/paste, find/replace, indent/unident selections, insert/overwrite mode, goto line. To Do's ------- - Add support for vegipete's FileDialog. - Add option to display row numbers next to the rows. - Add visual indicators of position within buffer. - Add Select-All key binding. - Maintain backup files when saving. - Add scroll current line to center/top/end key bindings. - Add resource utilization pop-up. - Add kill-to-end-of-line (Ctrl-K) keybinding. - Add case senstive search/replace keybindings. - Improve horizontal scrolling speed. - Improve search speed. Key Bindings ------------ F1 = Help F2/F9 = Save File/Save File as F3 = Load File F4 = Toggle Buffer F5 = Toggle Window split F10 = Quit Ctrl-O = Toggle Active Window Ctrl-F = Find Prompt/Selection Alt-F = Find Next Ctrl-R = Replace Prompt/Selection Ctrl-X/Y/P = Cut/Copy/Paste Ctrl-G = Goto Line INS = Toggle Insert/Overwrite mode Home 1x/2x/3x = Go To Start of Line/Page/Buffer End 1x/2x/3x = Go To End of Line/Page/Buffer Tab/Shift-Tab = Indent/Unindent Line/Selection Shift-Navigation Key = Start/Extend Selection Ctrl-Z = Undo F7 = Start Macro Recording F8 = Stop Macro Recording / Playback recorded macro Alt-C = Toggle Syntax Highlighting On/Off Alt-K = Show Key Code at prompt Alt-S = Screenshot Limitations ----------- - Max. 14000 lines across all buffers (including clipboard and undo buffer). - Max. 2 windows - Max. 2 buffers - Console Only - Text entered on find prompt can't include double quotes or commas. Find selection can includes double quotes and commas however. - Tested on FW version 5.0505 only. Epsilon CMM2 projects |

Really nice. Interestingly I can't open the code on my CMM2 in edit, I get a "Not enough internal memory" error. The code does open in xedit though |

| epsilon Senior Member Joined: 30/07/2020 Location: BelgiumPosts: 255 |
Yes, you need xedit to edit xedit. Isn't that cool At more than 4000 lines xedit.bas probably got too big for edit. Maybe I should split the file and use #include but that would mean multiple files to transfer and keep track of. xedit can in theory accept files of up to 14000 lines but that number includes clipboard and undo buffer lines as well. They all allocate out of the same pool of lines. So in practice you probably should go much higher than 7000 lines. Epsilon CMM2 projects |
