Add support for interpolated strings ("interstrings") (#369) * Update grammar to support interpolated strings * Struct initializers, case switchs are regular strings * Initial stub for interpolated string in AST This splits the previous STRING_LITERAL terminal into a production, stringLiteral, to handle REGULAR_STRING terminal and interpolatedString production. * Change interpolated strings to expressions * Fix mode handling in grammar * Grammar fixes - Fix mode handling in lexer - Interpolated strings only have one expression * Can successfully parse, stub compile interstrings $"He {there + print("hello")}"; * Add formatting string to grammar * Fix tests, and add test stubs * Rename curleys to brace; better AST generation * initial work interstring instruction * Initial work on formatted string instruction: emit * Formatted string instruction: execution * Add simple formatted string test * Add formatted string test src * Review changes #1 - Rename `FormattedString` to `FormatExpression` - Rename overloaded `try_to_format()` to `get_formatted()` * Review changes part 2 - Rename `InterpolatedString` ast node to `InterpolateString` * Review changes part 3 - Modify `ins_interpolate_string` * Review changes part 4 - Remove unused formal parameter * Add negative tests * Spruce up positive tests * Fix braces, escape chars inside interstring * Fix, add tests for escaped char and double brace * Address differences for new lines in tests * Update Escript version * Make empty expression an error * Add documentation for interpolated strings * Quick touchup on docs 2021-03-11 22:48:16 +01:00			`var i := 0, j := 0;`
