The em string interpolator works like the i string interpolator, but marks nonsensical errors
using <nonsensical>...</nonsensical> tags.
The em string interpolator works like the i string interpolator, but marks nonsensical errors
using <nonsensical>...</nonsensical> tags.
Note: Instead of these tags, it would be nicer to return a data structure containing the message string
and a boolean indicating whether the message is sensical, but then we cannot use string operations
like concatenation, stripMargin etc on the values returned by em"...", and in the current error
message composition methods, this is crucial.
General purpose string formatter, with the following features:
General purpose string formatter, with the following features:
1) On all Showables, show is called instead of toString
2) Exceptions raised by a show are handled by falling back to toString.
3) Sequences can be formatted using the desired separator between two % signs,
eg i"myList = (${myList}%, %)"
4) Safe handling of multi-line margins. Left margins are skipped om the parts
of the string context *before* inserting the arguments. That way, we guard
against accidentally treating an interpolated value as a margin.
