Running ToyEd from source requires Tcl/Tk 8.6 or newer, with Tklib. Both are available on most Linux distributions, or else from the tcl-lang.org website.
ToyEd was born from the experience of developing Scrunch Edit TT, and reuses most code from it.
You can usually find me on IRC, in the #ctrl-c channel of tilde.chat, or else as @notimetoplay on the elekk.xyz Mastodon instance. Would love to hear from you.
