"blank line" was intended to mean "line with no characters at all" so the spec is ambiguous there.
from go-jsonnet.
So the reason these are working is that the indentation level is chosen as w = 2 (actually since we have to handle a mix of tabs and spaces it's expressed as w = " "
) and then that's stripped off every line until you see a ||| without w on the front.
from go-jsonnet.
I'll write your examples again but with .
for the space character and not .
for arbitrary text:
|||
..
.. test
..|||,
.. ||| x
|||
|||
..
.. test
.. |||,
.. ||| x
|||
from go-jsonnet.
What's bad about this is the number of spaces on the first line (even though the line only has spaces on it) will change the amount of indentation that is stripped off of the remaining lines. But this is what meaningful whitespace is all about, I'm not sure anything can be done about that.

Thanks for the reply.
(edit: previous text here was incorrect, removing)
from go-jsonnet.
Ohh, I think actually I understand now. The spec is really difficult to read here. But basically because those lines begin with ..
, they don't end the block.
The block only ends if it has LESS or DIFFERENT whitespace at the start. Is that correct?
from go-jsonnet.
Yeah that's right. I will update the spec and it's probably worth having some examples in the language reference too.
from go-jsonnet.
Got it, thanks. Feel free to close this then, or maybe only after you update the spec ;)
from go-jsonnet.
One more thing to note, the ending behavior should probably also specify "ends at the first NON-BLANK subsequent line that does not begin with W", since adding "blank" lines in the middle of a block seems to work fine. (or that's a bug if not intended)
from go-jsonnet.
True, and you can also have blank lines at the end I think (just before the final |||
)
from go-jsonnet.
I suppose we could clarify the spec here.
