----------------------------------------
Bug #17107: Backtick in backtrace is a little bit annoying
https://bugs.ruby-lang.org/issues/17107
* Author: ioquatix (Samuel Williams)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
In Ruby exception backtrace (and other places), the method name uses a quoting style of a backtick followed by a text/name followed by an apostrophy.
```
in `<main>'
```
The quoting style is not safe, as in, it cannot be relied upon for parsing, because it's easy to inject quotes into the output stream:
e.g.
~~~
irb(main):006:0> self.send(:"I'm Great")
Traceback (most recent call last):
4: from /tmp/64556713-b3a1-40a1-b458-bfed3fec55b2:8:in `<main>'
3: from <internal:prelude>:20:in `irb'
2: from /tmp/64556713-b3a1-40a1-b458-bfed3fec55b2:5:in `<main>'
1: from /tmp/64556713-b3a1-40a1-b458-bfed3fec55b2:6:in `rescue in <main>'
NoMethodError (undefined method `I'm Great' for main:Object)
~~~
Note the last line now has ambiguous quoting.
- Should we fix this quoting style?
- Should we remove this quoting style?
- Should we choose some other quoting style?
As a specific point:
- Can we use two apostrophes rather than a backtick/apostrophe? Backticks often have a special meaning (e.g. markdown) which makes it somewhat annoying to copy and paste.
