Conrad Irwin created JRUBY-6473:
-----------------------------------
Summary: __LINE__ is incorrect when using eval() with binding
objects.
Key: JRUBY-6473
URL: https://jira.codehaus.org/browse/JRUBY-6473
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules, RubySpec
Reporter: Conrad Irwin
Priority: Minor
MRI has traditionally preserved the value of __LINE__ inside binding objects; a
fact that is relied on by Pry to discover where the user "is" in relation to
their source-code. (https://github.com/pry/pry/issues/475). Jruby nearly
implements this, but it relies on binding.getFrame().getLine() (as of
c9acf3b44b5651dd9a7f483b2a425dc25bfe1998), which unfortunately seems not to
point to the line currently being executed.
To get round this problem it's possible to instead use the same information as
used to populate the caller() array,
https://github.com/ConradIrwin/jruby/commit/e1272dc07455a34dfca063b9a82a6819295cdee8,
though I'm sure there are better ways.
