Single period char crashes ispry

[elcritch]

Trying out Spry. Interesting language!

I got this error when adding a period (".") to see what it'd do copying some smalltalk syntax I've seen:

Welcome to interactive Spry!
An empty line will evaluate previous lines, so hit enter twice.
>>> 1 + 1
>>> 
2
>>> . 
>>> 
spryvm.nim(383)          raiseParseException
Error: unhandled exception: Malformed local eval word, missing at least 1 character [ParseException]

I doesn't seem like an expected error.

Just found another one! :-)

>>> 1
>>> 
1
>>> :a
>>> 
SIGSEGV: Illegal storage access. (Attempt to read from nil?)

Here I'm trying to understand why the repl keeps printing out the last value. I found it trying to understand why this yields a 1 on the last range:

>>> 1 to: 5 do: [echo :x]
>>> 
1
2
3
4
5
1

The last "1" is the "print the result of the expression" which is the receiver in this case - 1. So that always get's printed.

I am busy today with lots of stuff but will be around later this evening, there is also a Discord server for chatting a bit :)

Ok, thanks! I'm not sure what's expected or not. I'll look up the Discord channel, or send an email to figure out when you'll be around.

There are several error handling holes for sure, but has not been my focus :) Den lör 25 apr. 2020 10:49Jaremy Creechley <notifications@github.com> skrev:

For sure! I understand that, maybe I can help some. Sent you an email.

maybe I can help some.

That'd be awesome - @gokr had some big plans with Spry and despite my lack of time, I'm highly interested in Spry (see e.g. #14 ).

So... yeah, there is a specific word type called "local word" which has the syntax ".xxx". This is a word type that I actually haven't documented in the manual (I now note), so a single period has no meaning in Spry so Spry expects at least one more character to form such a word.
