<b class="header" style="margin-top: 20px;">0.9.2</b>
|
||||
Specifying the start and end of a range literal is now optional, eg. <tt>array[3..]</tt>.
|
||||
You can now say <tt>a not instanceof b</tt>.
|
||||
Fixed important bugs with nested significant and non-significant indentation (Issue #637).
|
||||
Added a <tt>--require</tt> flag that allows you to hook into the <tt>coffee</tt> command.
|
||||
Added a custom <tt>jsl.conf</tt> file for our preferred JavaScriptLint setup.
|
||||
Sped up Jison grammar compilation time by flattening rules for operations.
|
||||
Block comments can now be used with JavaScript-minifier-friendly syntax.
|
||||
Added JavaScript's compound assignment bitwise operators. Bugfixes to
|
||||
implicit object literals with leading number and string keys, as the subject
|
||||
of implicit calls, and as part of compound assignment.

<b class="header" style="margin-top: 20px;">0.9.1</b>
|
||||
Bugfix release for <b>0.9.1</b>. Greatly improves the handling of mixed
|
||||
implicit objects, implicit function calls, and implicit indentation.
|
||||
String and regex interpolation is now strictly <tt>#{ ... }</tt> (Ruby style).
|
||||
The compiler now takes a <tt>--require</tt> flag, which specifies scripts
|
||||
to run before compilation.

<b class="header" style="margin-top: 20px;">0.9.2</b>
|
||||
Specifying the start and end of a range literal is now optional, eg. <tt>array[3..]</tt>.
|
||||
You can now say <tt>a not instanceof b</tt>.
|
||||
Fixed important bugs with nested significant and non-significant indentation (Issue #637).
|
||||
Added a <tt>--require</tt> flag that allows you to hook into the <tt>coffee</tt> command.
|
||||
Added a custom <tt>jsl.conf</tt> file for our preferred JavaScriptLint setup.
|
||||
Sped up Jison grammar compilation time by flattening rules for operations.
|
||||
Block comments can now be used with JavaScript-minifier-friendly syntax.
|
||||
Added JavaScript's compound assignment bitwise operators. Bugfixes to
|
||||
implicit object literals with leading number and string keys, as the subject
|
||||
of implicit calls, and as part of compound assignment.

<b class="header" style="margin-top: 20px;">0.9.1</b>
|
||||
Bugfix release for <b>0.9.1</b>. Greatly improves the handling of mixed
|
||||
implicit objects, implicit function calls, and implicit indentation.
|
||||
String and regex interpolation is now strictly <tt>#{ ... }</tt> (Ruby style).
|
||||
The compiler now takes a <tt>--require</tt> flag, which specifies scripts
|
||||
to run before compilation.
