pkhuongdo you think slime could use the current readtable to know whether to treat, e.g., [] and {} as list delimiters?
RiastradhTreat those as delimiters in what context, precisely?
pkhuongRiastradh: indentation, mostly.
nyefpkhuong: How would it know, other than by trying to READ them?
rudipkhuong: slime doesn't do indentation; you'd have to hack cl-indent.el
tritchey_is there anything that might be left around in an sbcl build that sh clean.sh wouldn't, err _clean_ that might cause problems if I moved the tree to a different machine?
rr--"{ up | down | lower | higher } in the call stack"
Zhivagowhat's the difference between up and higher?
rr--this terminology assumes the convention that the call stack grow ... up? down? no convention?
grows
everyone has their own convention?
pkhuongnyef: get-macro-character != nil looks like a decent heuristic.
nyefminion: Advice on heuristic?
minion#11953: Of course, this is a heuristic, which is a fancy way of saying that it doesn't work.
nyefrr--: Interestingly, it assumes that activation records are provided as a -stack-.
(Why yes, some people do heap-allocate function activation records.)
pkhuong: Would you expect #\< to be a macro character in any custom readtable that can still parse most lisp code?
What about funky syntaxen which can mix [ with } as a delimiter?
There are interesting possibilities in terms of parsing lisp code via the reader with lispm-style rubout handling style hacks in the underlying streams...
pkhuongnyef: xmlisp? (:
nyefWas more thinking xml-mixed-mode, tbh.

I joined on another network and was the only one in there and I thought "did everyone just decide to give up lisp for good?"
rahulyou didn't get the memo?
nyefHeck, even I've been doing some work in that-other-python.
rr--is there a special/specific term for the process/step whereby the reader converts symbol names to upper case
rahulgasp
nyefrr--: Maybe? It doesn't always happen, and the readers behavior is fairly well specified, so the spec might have a name for it.
rr--maybe something along the lines of 'canonicalization' (i am just making that up)
rahulfor presentational simplicity, the examples assume that the readtable case of the current readtable is :upcase.
thta's all I can find about case
nyefWell, the spec doesn't seem to have a name for the process, preferring to describe it longhand each time.
(sections 2.2 and 23.1.2.)
rahulyeah
it's merely an 'effect'
I'd call it case conversion
althought the algo described in 2.2 for this is not really the right one, considering :invert
nyefHow so?
rahulyou need to preserve case until you get to the end of the token because you don't know if _all_ the chars are of the same case till you're done
nyefAhh.
