* Former "isabelle tty" has been superseded by "isabelle console", with implicit build like "isabelle jedit", and without the mostly obsolete Isar TTY loop.
This refers to Isabelle/0e41f26a0250. Recently, I've found myself more often doing an 'exit' of the Isar loop of "isabelle tty" instead of actually using it.
Note that low-level system tinkering of the Isar toplevel may be done with ML use_thy and an auxiliary .thy file, potentially together with Toplevel.interactive := true for precise imitation of that "mode", which often causes the actual problems in the first-place. (I hardly do that myself, though, but use the Prover IDE directly for debugging and tinkering.)
Are there any remaining uses of the Isar toplevel? Otherwise it is something to be scheduled for eventual removal -- it complicates many aspects of the system.
