* $let widget added and tested
* Documentation for $let, doc improvements for $vars
* let properly avoids refreshing when possible
* $let Changes as recommended by others
* Removed superfluous super method call
Also improved $let test
* Fixes issue with #4504 and importvariable copying
ImportVariables widget was using $tw.utils.extend to copy the
variables from temporary set widgets into itself. However,
$tw.utils.extend does NOT behave like Object.assign. It not only
copies all self-owned variables over, but also all variables
in that object's prototype chain. This led to some redundant copying,
and a problem where some variables might show up more than once
(like transclusion).
Fixed now. importvariables widget does its own copying, since it
can't rely on $tw.utils.extend to do the right job, and it can't
count on Object.assign to be there.
* Added test to prevent reversion of #4504
* Slight corrections to new importvariables test
* Changed importVariable to store its ownvariables
Before, importVariables was creating a setWidget for every single variable it would find in its tiddlers, and it would create a long-ass call tree. Now, instead, it just accumulates the variables in itself.
* Can't use Object.assign
Learned the hardway while working on tw5-relink that Object.assign
doesn't exist in IE11. Using $tw.utils.extend instead.
* Retaining setWidget transclusion flexibility
* One more test to verify mixing sets and macros
* process.exit() only exist in a node.js environment
* updateInterval has been removed from upstream
From upstream commit:
b6eb9a4d5e
* Update Jasmine to 3.4.0
* Reuse the evalInContext helper
* Fix expected parse result to match the actual result
* 'describe' cannot be nested inside 'it' blocks
Jasmine started to explicitly raise an error in these cases since:
https://github.com/jasmine/jasmine/pull/1411
* Be consistent about how to refer to library files
* Update link to Jasmine's official website
They don’t get automatically decoded when the browser reads the
resulting HTML. So, instead, we’ll solve
1e9e1a1fdc by switching to double quotes
for attribute values.
