Rainbow parentheses?

[m-bob]

I'd appreciate an option to have rainbow parentheses in the repl. For me, it would make the repl seem more "alive."

[koji-kojiro]

Thanks for suggestion.

Currently, it is difficult to implement immediately because the repl doesn't count parentheses to check input, though that sounds very nice.

Thanks for your quick and kind reply. Thanks also for making this repl!

Rainbow parentheses are more a "it would be nice to have" feature, rather than a high-priority issue.

Yours,

Murray

PS: I can probably figure this out sometime, but when I start the repl I always get

Lock on package COMMON-LISP violated when setting the value of VALUES while in

package COMMON-LISP-USER.

I can fix that (for the remainder of the session by choosing restart 2), but perhaps there's a better solution?

Example:

06:57:00 ~ 501 > cl-repl

---

/ )( ) __ ( ( )( _ ( )

( ( / (/\ () ) / ) _) ) _// (/\

_)__/ (_\)()() __/

cl-repl 0.5.0 on Roswell 18.1.10.87, SBCL 1.4.4

See also: The SBCL Manual, Node "Package Locks" The ANSI Standard, Section 11.1.2.1.2

[Condition of type SYMBOL-PACKAGE-LOCKED-ERROR]

Restarts:

0: [CONTINUE] Ignore the package lock.

1: [IGNORE-ALL] Ignore all package locks in the context of this operation.

2: [UNLOCK-PACKAGE] Unlock the package.

3: [*ABORT] Deduce debugger level.

4: [*EXIT] Exit CL-REPL.

5: [*RETRY] Try evaluating again.

6: [RETRY] Retry EVAL of current toplevel form.

7: [CONTINUE] Ignore error and continue loading file NIL.

8: [ABORT] Abort loading file NIL.

9: [CONTINUE] Ignore runtime option --eval "(ros:run '((:eval\"(ros:quicklisp)\")(:script \"/Users/murray/.roswell/bin/cl-repl\")(:quit ())))".

10: [ABORT] Skip rest of --eval and --load options.

11: [ABORT] Skip to toplevel READ/EVAL/PRINT loop.

12: [EXIT] Exit SBCL (calling #'EXIT, killing the process).

Usage:

Ctrl+r: select restart. Ctrl+t: show backtrace.

That should be treated as another issue. Could you open the issue and give backtraces also?

[m-bob]

Will do. (Not sure about what you mean by backtraces: but I'll include the output I sent you, with a bit more explanation of what happens.

Again, thanks!

Yours,

Murray

You can get backtraces by Ctrl-t before exiting debugger. Sorry for the lack of explanation. Anyway, thank you for the bug report.

related: it is now possible to add two parens ( ) and move the cursor in-between, I just added cursor movement commands to cl-readline: [backward, forward]-[char, world].
