 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Amazing, seems more responsive and better featured than the inbuilt EDIT. If it were not for the fact that I'm generally working through TeraTerm or PuTTY I would definitely be using this in preference. One bug I've noticed running with 5.06.00b2, pressing F1 for Help reproducably reports: Error in line 920: Not enough heap memory Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Thank you Tom. I was worried that I would be pushing the heap a bit too hard in certain configurations. The help overlay is currently a huge sprite, which probably goes onto the heap. With some BLIT and/or PAGE COPY work I should be able to avoid (ab)using a sprite for the overlay. Still, the fact that one (big) sprite can trigger a heap overflow probably means I'm cutting is a bit too close. In the interim, you can reduce the MAX_NUM_ROWS% value on line 175 to something like 10000. That should free up enough heap. I'm putting serial input (not output), with alternative keybindings, on the to-do list. Epsilon CMM2 projects |

That would help. I'm hopeful a better VT100 compatible editor is possible from BASIC too, but xEdit is probably not the correct starting point. My personal gold standard for serial input would probably be an implementation of Vim, which I know isn't everyone's cup-of-teat. If that existed I might even bother to learn the Vi keystrokes beyond the basics I currently grasp ... maybe one day I'll even get around to implementing it myself.

I agree with Tom, if it was usable over TeraTerm it would be my editor of choice. At the risk of being cheeky, a killer function for me would be the ability to move quickly between files with a buffer intact (cut & paste between files, file explorer) Working with includes is OK using the current editor, but the ability to move around in a "project" would be great (obviously not a an implementation of VS Code on the CMM), but as an illustration.  Is it possible to make the keyword list customisable? Edited 2020-11-23 00:18 by elk1984 |

I'm holding out for vegipete's upcoming Ultrabox implementation for the file dialog/explorer type of functionality. The keyword list is customizable. All the keywords are defined in CMD_LIST_DATA block starting at line 372. If you're adding or removing keywords, make sure you also update the NUM_COMMANDS constant (which I realize now is a misnomer, sorry), just before, at line 368. CONST NUM_COMMANDS% = 219 DIM CMD_LIST$(NUM_COMMANDS%-1) LENGTH 16 CMD_LIST_DATA: DATA " ,%$!()=<>/\*+-:" 'Whitespaces DATA "ADC","BOX","CLEAR","CONTINUE","DATA","DO","END","SELECT","EXECUTE","EXIT","SUB","FUNCTION" DATA "I2C3","IRETURN","LIST","MAP","MKDIR","ONEWIRE","PIN","PORT","READ","RMDIR","SERVO","SPI2" DATA "TEXT","TURTLE","WII","ARC","CASE","CLOSE","COPY","DATE","EDIT","CSUB","FILES","GOSUB","IF" DATA "KILL","LOAD","MAP","MODE","OPEN","PIXEL","PRINT","REM","RUN","SETPIN","SPRITE","TIME" DATA "UPDATE","FIRMWARE","XMODEM","AUTOSAVE","CASE","ELSE","CLS","CPU","DEFINEFONT","ENDIF" DATA "FONT","GOTO", "IMAGE","LET","LOCAL","MATH","NEW","OPTION","PLAY","PULSE","RENAME","SAVE" DATA "SETTICK","STATIC", "TIMER","VAR","BITBANG","CHDIR","COLOUR","DHT22","ERASE" DATA "FOR","I2C","INPUT","LINE","LONGSTRING","MEMORY","NEXT","PAGE","POKE","PWM","RESTORE" DATA "SEEK","SORT","TRACE","WATCHDOG","BLIT","CIRCLE","CONST","DAC","DIM","ELSEIF","ERROR" DATA "FRAMEBUFFER","I2C2","IR","LOOP","MID","ON","PAUSE","POLYGON","RBOX","RETURN","SPI" DATA "TEMPR","START","TRIANGLE","WHILE","THEN","INSTR","CHR","ASC","VAL","STR","AND" DATA "OR","XOR","INV","INT","WRITE","SHOW","NOT","SKIP","LOADARRAY","SPACE","RGB" DATA "LEN","LEFT","RIGHT","EOF","MAX","MIN","COLOR","UCASE","LCASE","LCOMPARE","HIDE" DATA "SAFE", "MM", "INFO", "DEVICE", "ERRNO", "ERRMSG", "HRES", "VRES", "PEEK", "MOD" DATA "INTEGER", "STRING", "FLOAT", "OFF", "OUTPUT", "RANDOM" DATA "INCLUDE", "TO", "LENGTH", "UNTIL","IR","LS" DATA "ABS", "ACOS", "ASC", "ASIN", "ATAN2", "ATN","BAUDRATE","BIN" DATA "BIN2STR", "BOUND", "CINT", "CLASSIC", "COS","CWD" DATA "DATETIME", "DAY", "DEG", "DIR", "DISTANCE", "EPPOCH", "EVAL", "EXP" DATA "FIELD", "FIX", "FORMAT", "GETSCANLINE", "GPS", "HEX", "INKEY", "KEYDOWN" DATA "LGETBYTE", "LGETSTR", "LINSTR", "LLEN", "LOC", "LOF", "LOG", "NUNCHUK", "OCT" DATA "PI", "PULSIN", "RAD", "RND", "SGN", "SIN","STR2BIN", "SQR", "STR", "TAB", "TAN" Epsilon CMM2 projects |

Yeah, I get the hint.  I was side tracked with the octahedron and my latest game porting. This game though needs the ability for the user to select a file, so I must get back at it. I was working on a dialog box routine but perhaps I was getting ahead of myself trying to encode colour in the display string. Back to basics. ==================== For XEdit, I don't understand why you would bother make it work via serial port at all. My CMM2 is connected via serial port to a PC. When I need to do some serious editing, I use Notepad++. To me it makes no sense to use an editor on the CMM2 via serial port when the host computer can do a so much better job. I _do_ use the built in editor for quick tests, syntax fixes, etc but as soon as more extensive editing is required, I "LIST ALL" the program back to the PC and work there. Now it would be cool if there were an OPTION that allowed us to change what got used when the "EDIT" command is typed. Visit Vegipete's *Mite Library for cool programs. |

hi good job just 1 question: Why I can't use black color for background when I change to RGB(0,0,0), all text color and back color are same CONST BG_COLOR% = RGB(0,0,0) |
||||
| epsilon Senior Member Joined: 30/07/2020 Location: BelgiumPosts: 255 |
It has to do with black being treated as transparent, which is used for the syntax highlighting implementation (Syntax highlighting is actually inverted printing over colored boxes). The darkest gray that doesn't get mapped to black in MODE 1,8 appears to be RGB(32,32,32). On my old monitor this is indistinguishable from true black. Epsilon CMM2 projects |

Watch for V5.06.00b6. I'm introducing a new "colour" - NOTBLACK. For any mode this will be the darkest colour that can be displayed that will not act as transparent. I'll also make a change to the colour map so in 8-bit modes this colour really does look BLACK |

Perfect. Thank you Peter! On the topic of transparency, I was wondering if there's an as of yet undocumented m-value in the PRINT @(x,y,m) expression that does a 'transparent letters, background colored background' print? Currently, to achieve that effect I do a PRINT @(x,y,2) using black background, followed by a BLIT of that row of text to another page using 'orientation' value 4. Epsilon CMM2 projects |

Hi epsilon, isn't better to finish DATA with some special word and use it for calculating the count and dimensioning of the array. You need to go through it 2 times, but it's small array... DIM NUM_COMMANDS% = -1 DIM STRING keyWord = "" DATA_WITH_KEYWORDS: DATA "ADC","BOX","CLEAR","CONTINUE","DATA","DO","END","SELECT","EXECUTE","EXIT","SUB","FUNCTION" ... DATA "PI", "PULSIN", "RAD", "RND", "SGN", "SIN","STR2BIN", "SQR", "STR", "TAB", "TAN", "eNdOfKeYwOrDs" RESTORE DATA_WITH_KEYWORDS DO WHILE keyWord <> "eNdOfKeYwOrDs" INC NUM_COMMANDS% LOOP RESTORE DATA_WITH_KEYWORDS DIM CMD_LIST$(NUM_COMMANDS%) LENGTH 16 FOR NUM_COMMANDS% = 0 TO NUM_COMMANDS% READ LIST$(NUM_COMMANDS%) NEXT NUM_COMMANDS% NUM_COMMANDS% = UBOUND(LIST$()) 'I'm not sure if after loop is NUM_COMMANDS% +1 higher You then don't need to calculate keywords number...

Good idea Jiri. I'll make that change. Thank you for the suggestion! Epsilon CMM2 projects |

Peter, in the interest of readability, if you implement NOTBLACK as a predefined colour (shortcut form), would it be useful to also have TRASPARENT as a predefined colour shortcut ??? Just a thought. Womble |
||||
| jirsoft Guru Joined: 18/09/2020 Location: Czech RepublicPosts: 532 |
I think normal BLACK will be transparent. For me make more sense to have BLACK as almost black (=opaque) and then to have TRANSPARENT as total bleck (=transparent)... Jiri Napoleon Commander and SimplEd for CMM2 (GitHub), Â CMM2.fun |
||||
| Womble Senior Member Joined: 09/07/2020 Location: United KingdomPosts: 267 |
Yes, that would make more sense  |
||||
| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 8592 |
BLACK can't change as it would break many programs. NOTBLACK is what you get. Use or ignore as you wish |
||||
| Womble Senior Member Joined: 09/07/2020 Location: United KingdomPosts: 267 |
Fair enough, NOTBLACK it is. Thanks for that Peter, I'm sure it will prove useful. |

Is it possible to run BASIC programs from this editor, like you can with the built in editor? |
||||
| epsilon Senior Member Joined: 30/07/2020 Location: BelgiumPosts: 255 |
Not currently, but I'll add that to the ever growing todo list. I'm also working on a capability that lets you see from xedit the console screen as it was when you launched xedit, so you can see your trace list, previous program output, errors reported by MMbasic etc. Epsilon CMM2 projects |
