* Add initial support for template literals with no
interpolation
* Change ‘unexpected string’ error message tests to
use number not identifier prefix.
Identifer prefixes are now valid as tagged
template literals
* Test tagged template literals for non-interpolated
strings and tag function.
* Tagged template literals work for pure Strings.
Pull tagged template definition up to Invocation
level in grammar, enabling chained invocation calls.
We can view a tagged template is a special form
of function call.
* Readying for StringWithInterpolations work.
* Tweaks.
* Fix style
* Pass StringWithInterpolations parameter straight
into Call constructor.
StringWithInterpolations will be output as
template literal, so already in correct form for
outputting tagged template literal.
* Strip down compileNode for StringWithInterpolations
* Done StringLiteral case for interpolated Strings
* Remove need for TemplateLiteral
* Simplify code.
* Small code tidy
* Interpolated strings now outputting as template literals.
Still needs comprehensive testing.
* Move error message tests into error_messages.coffee; remove test that is testing for a Node runtime error
* Split up tests that were testing multiple things per test, so that each test tests only one thing
* Edge cases: tagged template literals containing interpolated strings or even internal tagged template literals
* Make more concise, more idiomatic style
* Pull back extreme indentation
* Restore and fix commented-out tests
* Edge case: tagged template literal with empty string
* Only use new ES2015 interpolated string syntax if we’re inside a tagged template literal; this keeps this PR safe to merge into CoffeeScript 1.x. Remove the code from this commit to make all interpolated strings use ES2015 syntax, for CoffeeScript 2.
* Compiler now _doesn’t_ use template literals.
* Expand tagged template literal tests
* Move ‘Unexpected string’ error message tests into
tagged template literal section.
‘Unexpected string’ is not reported in these test
scenarios anymore. Instead, we error that the
prefixing literal is not a function.
* Don’t unwrap StringWithInterpolations.
Saw bug with program consisting of “#{2}” not
compiling with template literals. Root cause was
that Block.compileNode was unwrapping interpolated
string and so didn’t use compileNode logic at
StringWithInterpolations level.
* No need to bracket interpolated strings any more.
When interpolated string looks like `hello ${2}`,
no extract brackets are needed, as the `s mark the
beginning and end.
* Show html templating with tagged template literals
* Multiline should match multiline
* Comment out unnecessary `unwrap`, which is only needed for CoffeeScript 2 all-ES2015 syntax output
