That is not enough.
See
https://github.com/fricas/fricas/commit/6fb0bbadfe376c05cce3c9cdd98606259b1f1b05
and the two followup fixing commits. In particular the script
fricas-readline is needed.

I also tried fricas with the -rl option as suggested by Ralf. After
installing the rlwrap program
wspage@desktop:~$ rlwrap --version
rlwrap 0.43
$ fricas -rl
Thank you Bill and Ralph.
Ok, I went back to 1.3.6. But I still see a problem:

True. Why did I do

In that case it definitely does not use clef.

Indeed. CLEF is the problem.
Just edit your fricas script. Edit the one in your PATH if you do not
want to recompile fricas.

Try starting fricas like this:
$ fricas -noclef
Doing this avoids the command line problem for me.
"clef" is the old Axiom alternative to readline and is still used by
default. Of course without clef (and without building FriCAS especially to
support readline) you lose the usual command line
Hi Ralf,
Thanks for responding. It may be that the master branch fixes (part) of
the problem.
Meanwhile I reverted to 1.3.5, which has this behavior:
(1) -> f(x) == c*x^2
Type: Void
(2) ->f(α))
Compiling function f with type Variable(α) -> Polynomial(Integer)
2
(2) c α
Hello Kostas,
thanks for reporting.
I simply typed one α and FriCAS is showing a double α on the input line.
Strange.
(3) ->αα
(3) α
Type: Variable(α)
But I cannot confirm your second problem.
(7) -> f(x)==c*x^2
I just found out that what I previously reported as a problem with the
TeXmacs interface also occurs
in "plain" FriCAS:
$ fricas
