(#112) * Fix typo in the help text when typing `js2coffee`. (#113) v0.1.2 - October 15, 2011 --------------------- Thanks to @Wisdom, @nilbus, @joelvh, @gabipurcaru, @michaelficarra, @tricknotes, @eventualbuddha, @clkao for the contributions. ### Fixed: * Fix misspelling in package.json. * Object lookups using object literals (`o[{a:1, b:2}]`) are now supported. * Fixed `js2coffee file.js` not working in Linux. (#90, #54) * Returning from an if without curly braces are now supported. (`if (x) return y;`)) (#50) * Returning object literals should now have the objects parenthesized properly. ( `return {x:1, y:2}`) (#52) * Always new-line objects to support `{ a: { b: c } }`. (#96, #94) * Reserved words are now allowed as property accessors. Fixes `object.on(...)`. (#97, #95, #75) * Empty switch cases now get compiled correctly. (#70, #28) * The value `undefined` now gets compiled properly. (#20, #85) * Declaring `var x` will now translate to `x = undefined`. (#79) * Updated reserved keywords list. (#25, #67) ### Changed: * Compile `!!` into `!!` instead of `not not`. (#30) * Implement CRLF support. Closes (#81, #88) * `!!!x` now condenses to `not x`. * `==` and `===` now become `is`. (#29) * `!(a instanceof b)` now becomes `a not instanceof b`. (#29) * Doing `var x = y` will now have different behavior for reserved keywords. (#79) ### Misc changes: * Fixed bad link in README. (#63) * Make `npm test` run tests. * Running tests now shows less output. * Running tests now exits with an error code when it fails. v0.1.1 - July 09, 2011 --------------------- ### Fixed: * Invert the 'a == null' behavior. (#19, #51) * Fix the problem where passing an anonymous function as a parameter can sometimes lead to syntax errors. (#55) v0.1.0 - June 13, 2011 --------------------- Lots of refactoring and new improvements. ### Added: * Single line ifs. `if (x) continue;` will now compile to `continue if x`. * Hide empty catches. (#32). * `try { .. } catch (f) {}` now becomes `try ..` without a catch. * Omit returns more agressively. (#42) * Omit many unneeded parentheses in certain cases. (#31) ### Fixed: * Fix `x.prototype.y` to be `x::y` instead of `x::.y` (#24) * The `in` operator now compiles to `of`. (#46) * `a in b` now compiles to `a of b`. * Fix floating point numbers. (#45) * Fix a problem with returning object literals. (#47) ### Refactoring: * Lots and lots of refactoring. * `Builder` is now a class (to support warnings in the future, and more). * Implement a new `Transformer` class to do AST transformations before building the compiled source. * Recursive functions now use `Node::walk()`. * Move stuff into `js2coffee/helpers.coffee` and `js2coffee/node_ext.coffee`. v0.0.5 - June 10, 2011 --------------------- Special thanks to [Michael Ficarra](http://github.com/michaelficarra) for agressively reporting issues and suggesting numerous improvements. ### Added: * Account for negative existence checks (`if !x?`). (#19) * Compile `if (x != null)` to `unless x?` * Compile `if (x === null)` to `if x?` * Ensure object literals with more than one property get surrounded by `({ .. })`. (#8) * Support `debugger`. (#27) * Support destructuring in functions. (#17) * Use `loop` instead of `while true` in while and for loops. (#35) * Use the `::` prototype operator. (#24) * Use `unless` and `until` as the inverse of `if` and `while` respectively. (#35) ### Fixed: * Keys in object literals now get quoted if needed. This fixes the erroneous compilation of objects such as `{ 'click #button': function() { ... } }`. v0.0.4 - June 09, 2011 --------------------- ### Changed: * Allow single-line JS comments without a newline in the end. * Enquote identifiers in object literals as needed. (#16) * Ensure that percent interpolation (%i) don't get messed up in the Node version. (#13) * Ensure that when anonymous functions are called, they are parenthesized. (#14) ### Added: * more tests. ### Fixed: * `++b` is now no longer erroneously translated to `b++`. * Fixed an issue where `{ off: 2 }` erroneously becomes `{ off_: 2 }`. * Returning object literals should now not create invalid CoffeeScript. (#15) ### Misc: * Annotate the source code. * Make a simpler (but less stringent) JS packing routine for `js2coffee.min.js`. v0.0.3 - June 05, 2011 --------------------- ### Fixed: * Narcissus to not go into an infinite loop in the browser. * Use `this` instead of `@` for better readability. (#10) ### Changed: * Implement += and friends. (#9) * Use 'cake' instead of 'make'. v0.0.2 - June 4, 2011 --------------------- ### Changed: * Better string escaping * Better handling of empty blocks * Support for commas (eg: `a = 2, b = 3`) * Returns and breaks are omitted when not needed * Switch/case now uses `switch` instead of `if` * Some other improvements v0.0.1 ------ Initial version.
