It works in terminal after install the *dev* package of libreadline. Thanks!
The problems may be valuable for other people, so I record it here.
The first method, run it on startup:
$ ./factor -run=readline-listener
no-such-symbol
name "rl_completion_entry_function"
library "readline"
(U) Quotation: [ c-to-factor -> ]
Word: c-to-factor
(U) Quotation: [ [ catchstack* push ] dip call -> catchstack* pop* ]
(O) Word: command-line-startup
(O) Word: readline-listener
(O) Word: set-rl_completion_entry_function
(O) Word: address-of
(O) Word: no-such-symbol
(O) Method: M\ object throw
(U) Quotation: [
OBJ-CURRENT-THREAD special-object error-thread set-global
current-continuation -> error-continuation set-global
[ original-error set-global ] [ rethrow ] bi
]
The second method, start it after launch:
$ ./factor -run=listener
IN: scratchpad USE: readline-listener
Loading resource:extra/readline-listener/readline-listener.factor
Loading resource:extra/readline/readline.factor
Loading resource:extra/readline/ffi/ffi.factor
Loading resource:extra/readline/readline-docs.factor
Loading resource:extra/readline-listener/readline-listener-docs.factor
IN: scratchpad readline-listener
no-such-symbol
name "rl_completion_entry_function"
library "readline"
Type :help for debugging help.
Both fails.
libreadline won't work in FUEL according to my understanding because
the communication medium between Factor and Emacs is a socket not a
pty.
I gave it a try and the same things(no-such-symbol) happened in "*fuel
listener*" buffer.
The distribution and packages installed on my computer related to readline are:
$ cat /etc/issue
Ubuntu 12.04.2 LTS \n \l
$ dpkg --get-selections | grep readline
libreadline6 install
readline-common install
After I install the *dev* package of libreadline:
$ sudo apt-get install libreadline6-dev
Both methods work in both terminal and *term* in Emacs. Great!
Finally:
* Is it worth to add one more line "-run=listener" in the output of "$
factor --help"?
* Most completion functionality in Emacs prefer reinvent the wheel to
use libreadline, for some good reasons and some limitation.
Many(if not all) of them just ignore libreadline. I think it is also
true for FUEL.
For curious, I also try the second method after install
"libreadline6-dev" in "*fuel listener*" buffer and it hangs...
Maybe it is worth to mention(in some place of documentation) that
"don't use readline-listener in FUEL, at least it won't work"?
