This looks too great to exist...
load = (name) ->
with io.open(name)
while txt = \read
print txt
(i meant that you should really make with statement interact with given object. This will not change basic syntax, but will allow with items["stick"]-like statements)
Can you un-clickbait the title? Also, I don't believe MoonScript supports assignment with while loops.
MoonScript really support it, e.g.
n = 0
foo = while n < 10
n += 1
n
foo will be a table have 1...10 as values.
It's not documented in the reference, then. I checked under the section for while - http://moonscript.org/reference/#the-language/while-loop - and couldn't see anything.
I believe you three are not talking about the same thing.
@RyanSquared said "this is wrong":
while txt = \read
print txt
You can already put any expression in a with statement. It's not possible to put assignment in a while loop.
Alternate syntax, that does work (in theory):
load = (name)->
with file = io.open name
print line for line in file\lines!
Please note that if you want this to be like Pythonic with so that it's garbage collected when the with line ends, that's not going to happen because with either syntax, the with statement returns the file, meaning it's now in the scope of the function calling load().
Would it be possible to compile while a = b to something like this?
local a, _fn
_fn = function ()
return a = b
end
while _fn() do
...
end
