Seems there his a limitation for the character number in a command line...

If i add this line:

Quote:
Ambient remove the ">>RAM:T/markdown.html" after a save and relaunch of the MIME editor.

[EDIT] A strange thing, the file is not changed (line is complete in the mimetypefile) but the line is not showed completly in the editor and the add of this command result to markdown.html don't work -> there is an output in a window instead ">>RAM:T/markdown.html"

this is the cmark-gfm executable to test:

and this is the mimetype:
https://www.morphos-storage.net/upload/test/x-markdown to copy to SYS:Prefs/Ambient/Filetypes/text/
