if-then-else example does not work

[zbuc]

The example for if-then-else in the documentation does not work correctly when you try to run it in the linked jqplay editor:

https://stedolan.github.io/jq/manual/#example74

https://jqplay.org/jq?q=%27if%20.%20%3D%3D%200%20then%0A%20%20%22zero%22%0Aelif%20.%20%3D%3D%201%20then%0A%20%20%22one%22%0Aelse%0A%20%20%22many%22%0Aend%27&j=2

Results:

jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Unix shell quoting issues?) at <top-level>, line 1:
'if . == 0 then
jq: 1 compile error
exit status 3

@zbuc - When using jqplay, you don't include the outermost quotation marks. Same thing if the jq program goes in a file. Indeed, the outermost quotation marks are sometimes not needed at all.

I followed the link directly from the documentation page, and did not manually change anything. It does not work as linked from the documentation.

I tried removing the single quotes, and it does work. This seems like a defect in the links included in the documentation.

@zbuc That's an example for you to use on a local shell, not on jqplay. I'm sorry, but there's no way to make the examples work for both.

[zbuc]

Then why is there a link to run it on jqplay if it doesn't work?

[zbuc]

@nicowilliams here, I found and fixed the bug. The regex being used only worked properly on single-line examples and failed on multiline ones.

#1570

@zbuc Oh! I never knew about that feature (the Run button). I use NoScript, and wasn't enabling the required origin for that...

This has been resolved by #1716, and also the commit 048acee in #1825 removes the newlines from the example, and the page was rebuilt at 76c044f, the issue no longer happens.
