Rob,
In Peter's latest cut of ArmMiteBasic (5.07.00b2), the list commands and list functions commands send lines longer than 80 (appears to be at least 88, possibly 96).
Is there any way to have GFXTerm handle longer lines (The long lines wrap OK but it makes the displayed data more difficult to read).
Doug.... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

hi, handling lines longer than 80 characters presents interesting problems to any terminal emulator, i have been considering this for a while with regards to the CMM2 use of 100 (or 101?) columns.
1. if you allow the user to resize the 80x24 terminal window, then anything that assumes a fixed 80 columns (or 24 lines) may thereafter break. for instance, an editor that assumes automatic line wrapping at 80 columns, or that clears the screen by writing 24 line feeds. the reason for the breakage may not be obvious to the average user, nor may it be obvious how to get back to an exactly 80x24 terminal window.
2. worse still, if you honour escape sequences from the remote (mmbasic) computer to resize the 80x24 terminal window, then you run the risk of the window being resized beyond the bounds of your LCD monitor. under linux this is handled fairly gracefully (albeit in a way most users are unaware of), but with windows things can quickly go to custard - for instance, the user being unable to get to the titlebar close button, automatic scrollbars being generated by windows where there is no screen space for them, etc. and again, the user may not be aware of how to get back to exactly 80x24.
as, essentially, a VT102 emulator, GFXterm 'sandboxes' the remote (mmbasic) computer within the 80x24 bound terminal area. in my view, this represent good programming practice.
i guess what i could do is create versions for further different sizes of terminal screen. right now there are already three (80 column) versions available, with: 24, 36, and 43 lines. this was done in response to several user requests, but to be honest i doubt if any more than a handful of people use anything other than the basic 80x24 version.
given all the available different font sizes and screen resolutions supported by the CMM2, how many different terminal sizes are required? i know of 101x50 (which the CMM2 originally had), but am sure there are others.
cheers, rob :-) Edited 2021-02-25 20:48 by robert.rozee

Basically dozens. The only proper solution is to allow flexible re-sizing and accepting the screen resize escape code same as teraterm or puppy

this essentially entails allowing the remote (mmbasic) computer to remotely control aspects of your main computer's desktop. a bit like popup windows generated by a web browser, which are heavily curtailed (or completely blocked) by most modern browsers.
when developing the win32 version of GFXterm, i quickly discovered how messy things could get if a window grew too large - basically, a window could grow to be 8 pixels larger than the physical screen dimensions, after which things went very wrong. many folks use GFXterm with large fonts, which means that at a 100x50 terminal size this limitation is easily hit.

Rob
I'm not asking for it. Merely pointing out that the line length on CMM2 is a function of 14 modes and 7 fonts, not counting any user loaded fonts

Thanks for the detailed response Rob, it is not a show stopper in any way - just thought I would ask the question Doug.... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

if F407 mmbasic supports OPTION DISPLAY lines [,chars] then a simple solution may be for it to check this setting and adjust the behaviour of LIST COMMANDS and LIST FUNCTIONS accordingly.
