Macros are broken (outside of the online REPL)
SkyyySi opened this issue · 3 comments
The code
macro INVERT = (var) ->
"#{var} = not #{var}"
$INVERT(x)used to be valid and produce the following Lua code:
local x = 5;
x = not xHowever, after having installed Yuescript 0.16.5, this behavior seems to be broken, with it now resulting in the following compilation error:
Failed to compile: test2.yue
5: left hand expression is not assignable
$INVERT(x)
^
However, weirdly, the online REPL seems to be unaffected by this.
Can you show me the full codes in your "test2.yue" ?
Can you show me the full codes in your "test2.yue" ?
Sure:
macro INVERT = (var) ->
print(var)
"#{var} = not #{var}"
$INVERT(x)The print statement prints that var is a nil value (note to self: why did strip that line out? That sounds like it's quite important here).
For good measure, I also tested this in the interactive (offline) REPL:
macro test = (x, y, z) -> "'#{x}, #{y}, #{z}'"When running that code as $test("foo", "bar", "biz"), I get back the string nil, nil, nil.
In case that helps, here's some info on my specific setup (since this issue doesn't occur in the online REPL, this issue may be related to that):
- OS: Arch Linux
- Lua version: 5.1
- Install method:
sudo luarocks install --lua-version=5.1 yuescript
I think the previous version of Yuescript I used was 0.16.1, but I also recently compiled just fine on a different, more recent setup on my laptop, so I'm guessing that this issue was only introduced in 0.16.5 or maybe 0.16.4.
