* Correct tagged template literal test.
Should use Coffeescript form of interpolated
strings, not Javascript!
* First pass at docs for tagged template literals.
* Correct alerted variable.
* Add note re checking runtime for tagged template literals
* Fixed broken example.
* Consistent style
* Clarify that CoffeeScript isn’t handling the tagged template literal, the runtime is; fix CoffeeScript spelling
* Collapse notes about generator functions and tagged template literals into the same sentence
* Make tagged template literals example into a function
* Make text less clunky.
* More clarity on what CoffeeScript is doing versus what the runtime is doing, and emphasize runtimes vs Babel/Traceur
* Remove moot `version` property from bower.json
Per bower/bower.json-spec@a325da3
* No need for bower to know about dev dependencies, and this is one less thing to keep in sync
* Documentation of `for...from` for iterating over generator functions
* Add note that the CoffeeScript compiler does not, in fact, generate JavaScript that runs in every JavaScript runtime 😢
* Docs shorthand object notation
A simple but slightly more imaginative example of shorthand object notation.
Closes#1808.

* Update for new documentation folder structure
* Fix typo
* The generated JavaScript for the examples in the docs ends up within index.html, so we don’t need the intermediate generated .js files committed in the repo; also, even while .gitignored they should be under `docs`, with the rest of the generated files, not under `documentation`, where the source files are.
* Add “Existential Operator” to the table of contents. Closes#4361
* Updated output due to newer version of highlight.js
* Generated the JavaScript for the docs examples should be synchronous, so that index.html isn’t generated before the JavaScript is
* In “Try CoffeeScript,” if you press the tab key it should type a tab character. Closes#3342.
* Rename doc example folders from `js` and `coffee` to just `examples`
* Add missing `yield` to the list of keywords to highlight until highlight.js catches up; update the class used to match highlight.js’ `keyword`
* `cake doc:site` should watch the example files too, not just index.html.js
* Remove examples folder, including underscore.coffee; remove link to annotated underscore.coffee
* Support JavaScript code blocks set apart by triple backticks (``` ... ```)
* Add test for escaped backticks
* Remove TODOs for things we’re never going to support
* Convert escaped backticks to backticks; update tests
* Block inline JavaScript can end with an escaped backtick character
* Updated JavaScript token regexes per @lydell
* In JavaScript blocks, escape backslashes when they immediately precede backticks; additional tests
* Test that we don’t break backslash escaping in JavaScript literals
* 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
* Added support for for-from loop, see #3832
* for-from: remove extra newline and add support for ranges
* for-from: tidy up the lexer
* for-from: add support for patterns
* for-from: fix bad alignment
* for-from: add two more tests
* for-from: fix test "for-from loops over generators"
See explanation here: https://github.com/jashkenas/coffeescript/pull/4306#issuecomment-257066877
* for-from: delete leftover console.log
* Refactor the big `if` block in the lexer to be as minimal a change from `master` as we can get away with
* Cleanup to make more idiomatic, remove trailing whitespace, minor performance improvements
* for-from: move code from one file to another
* for-from: clean up whitespace
* for-from: lexer bikeshedding
* Move "own is not supported in for-from loops" test into error_messages.coffee; improve error message so that "own" is underlined
* Revert unnecessary changes, to minimize the lines of code modified by this PR
Rather than compiling splats to arrays built using `Array#concat`, splats
are now compiled directly to ES2015 splats, e.g.
f foo, arguments..., bar
[ foo, arguments..., bar ]
Which used to be compiled to:
f.apply(null, [foo].concat(slice.call(arguments), [bar]));
[foo].concat(slice.call(arguments), [bar]);
Is now compiled to:
f(foo, ...arguments, bar);
[ foo, ...arguments, bar ];

This is an upstream port of https://github.com/decaffeinate/coffeescript/pull/10
See that PR for links to the issues that this fixes.
Just like OUTDENT and CALL_END tokens, close-curly-brace tokens can be generated
without having a real location, and if that position overlaps with a later
token, it can cause the AST to have bad location data. Just like the other two
token types, we now give `}` tokens the position of the previous real token,
which makes all AST nodes have reasonable locations.
* Eliminate wrapper around “bound” (arrow) functions; output `=>` for such functions
* Remove irrelevant (and breaking) tests
* Minor cleanup
* When a function parameter is a splat (i.e., it uses the ES2015 rest parameter syntax) output that parameter as ES2015
* Rearrange function parameters when one of the parameters is a splat and isn’t the last parameter (very WIP)
* Handle params like `@param`, adding assignment expressions for them when they appear; ensure splat parameter is last
* Add parameter names (not a text like `'\nValue IdentifierLiteral: a'`) to the scope, so that parameters can’t be deleted; move body-related lines together; more explanation of what’s going on
* For parameters with a default value, correctly add the parameter name to the function scope
* Handle expansions in function parameters: when an expansion is found, set the parameters to only be the original parameters left of the expansion, then an `...args` parameter; and in the function body define variables for the parameters to the right of the expansion, including setting default values
* Handle splat parameters the same way we handle expansions: if a splat parameter is found, it becomes the last parameter in the function definition, and all following parameters get declared in the function body. Fix the splat/rest parameter values after the post-splat parameters have been extracted from it. Clean up `Code.compileNode` so that we loop through the parameters only once, and we create all expressions using calls like `new IdentifierLiteral` rather than `@makeCode`.
* Fix parameter name when a parameter is a splat attached to `this` (e.g. `@param...`)
* Rather than assigning post-splat parameters based on index, use slice; passes test “Functions with splats being called with too few arguments”
* Dial back our w00t indentation
* Better parsing of parameter names (WIP)
* Refactor processing of splat/expansion parameters
* Fix assignment of default parameters for parameters that come after a splat
* Better check for whether a param is attached to `this`
* More understandable variable names
* For parameters after a splat or expansion, assign them similar to the 1.x destructuring method of using `arguments`, except only concern ourselves with the post-splat parameters instead of all parameters; and use the splat/expansion parameter name, since `arguments` in ES fat arrow functions refers to the parent function’s `arguments` rather than the fat arrow function’s arguments/parameters
* Don’t add unnamed parameters (like `[]` as a parameter) to the function scope
* Disallow multiple splat/expansion parameters in function definitions; disallow lone expansion parameters
* Fix `this` params not getting assigned if the parameter is after a splat parameter
* Allow names of function parameters attached to `this` to be reserved words
* Always add a statement to the function body defining a variable with its default value, if it has one, if the variable `== null`; this covers the case when ES doesn’t apply the default value when `null` is passed in as a value, but CoffeeScript expects `null` and `undefined` to act interchangeably
* Aftermath of having both `undefined` and `null` trigger the use of default values for parameters with default values
* More careful parsing of destructured parameters
* Fall back to processing destructured parameters in the function body, to account for `this` or default values within destructured objects
* Clean up comments
* Restore new bare function test, minus the arrow function part of it
* Test that bound/arrow functions aren’t overwriting the `arguments` object, which should refer to the parent scope’s `arguments` (like `this`)
* Follow ES2015 spec for parameter default values: `null` gets assigned as as `null`, not the default value
* Mimic ES default parameters behavior for parameters after a splat or expansion parameter
* Bound functions cannot be generators: remove no-longer-relevant test, add check to throw error if `yield` appears inside a bound (arrow) function
* Error for bound generator functions should underline the `yield`
