BBS: TELESC.NET.BR Assunto: Feature request: JS petsc De: Mindsurfer Data: Sat, 21 Feb 2026 21:37:00 +0000 ----------------------------------------------------------- Re: Feature request: JS petscii-to-cp437/ascii converstion function By: Eric Oulashin to GitLab issue in main/sbbs on Thu Feb 19 2026 14:15:11 EO> open https://gitlab.synchro.net/main/sbbs/-/issues/1074 EO> m1ndsurfer mentioned that some file_id.diz file descriptions for Commodore EO> 64 files have PETSCII characters in them, which naturally don't display EO> properly if the user's terminal doesn't support PETSCII. It might be EO> handy if there was a JavaScript function to convert PETSCII to EO> ASCII/CP437. My file lister would probably be able to use such a function EO> to convert PETSCII to ASCII/CP437 if the user's terminal doesn't support EO> PETSCII (and a JS function like str_is_petscii(), similar to str_is_utf8() EO> & others, could be useful too). It looks like the Synchronet C++ code EO> might have internal functionality already? (petscii_to_ansibbs()) Actually it was about D64 disk images and their directory of files. The file directories/ 0 byte filnames are using petscii chars to generate nice looking descriptions, logos etc. very similar to what is used in file_id.diz files. They use 0byte files and the filenames are used to display some petscii graphic in several rows of filenames. The idea is to have a way to extract those file directory listings out of the c64 disk images and somhow, when requested, present them as sixel images to the bbs user. I know there are libraries that convert petscii into cp437 so it looks at least a bit similar, but thats not what i meant. i have created a bash script now that can extract the file directory via cc1541 (thats a software emulating a 1541 floppy disk drive,) prepare and convert the extracted data to be turned into an image via ImageMagick using a monospace C64 TTF font. Again, the idea was to have for a D64 file, what we have as file_id.diz import from a ZIP file. Especially scene releases have some very nice Petscii graphic stored into the file direcory rows of an C64 disk image =) Mindsurfer --- Synchronet FuNToPiA BBS - telnet://funtopia.synchro.net:3023 ssh:3022 * Origin: Vertrauen - [vert/cvs/bbs].synchro.net (1:103/705) ----------------------------------------------------------- [Voltar]
