[Flashforth-devel] Fwd: Re: ff-shell and the Raspberry Pi

[Mikael N. <mik...@fl...>]

Hi,
In the python shell I have command history and line editing functions.
There the line_edit (=readline) function blocks the output from FF.
Thats why the python shell has two threads, one for input and one for 
output.

I am sure there is a readline function for TCL somewhere also that could 
be used for line edit and history.
Some redesign of the TCL shell would be needed though.

There are some things missing in the python shell, at least listing of 
files and directories and change of directory could be added.
