E01093: a backtick String is never closed - it runs to the end of the file

What went wrong

A backtick String was opened and never closed: `${count} items" A double quote cannot end a backtick String, so the String runs on to the end of the file - and the parser gives up at the LAST line, far from the mistake. This error points at the backtick that opened it.

Worked examples

Compilable examples demonstrating this error and the correct fix:

• ek9 -q 43 (How do I escape characters in EK9 string interpolation?)
• ek9 -q 909 (How does $ work inside backtick strings in EK9?)

How to fix it

Close a String with the delimiter that opened it:

• `${count} items" --> `${count} items`
• "${count} items` --> `${count} items` (interpolation needs backticks)

A backtick meant as text inside a backtick String is written \`

Common causes

• Mixing the two delimiters: EK9 has "plain" and `interpolated` Strings
• Adding ${...} to a double-quoted String and changing only one quote
• A backtick meant as text inside a backtick String, not escaped as \`

Examples

Every example is compiled by the EK9 compiler: the first fails exactly as captioned, the others fix it.
