ri\_cal version 0.7.7 has been released!

NOTE: This is identical to 0.7.6 other than the version number. For  
some reason github failed to publish a gem for that version.

- [http://ri-cal.rubyforge.org/](http://ri-cal.rubyforge.org/)
- 

A new Ruby implementation of RFC2445 iCalendar.

The existing Ruby iCalendar libraries (e.g. icalendar, vpim) provide  
for parsing and generating icalendar files,  
but do not support important things like enumerating occurrences of  
repeating events.

This is a clean-slate implementation of RFC2445.

A Google group for discussion of this library has been set up  
[http://groups.google.com/group/rical\_gem](http://groups.google.com/group/rical_gem)

Changes:

### 0.7.7 - 6 August 2009

- No changes other than a version number bump. github seems to  
have failed to notice the commit of v0.7.6  
and didn’t build the gem. Hopefully it will notice this one.

### 0.7.6 - 6 August 2009

- Fixes  
http://rick\_denatale.lighthouseapp.com/projects/30941/tickets/20  
RiCal::PropertyValue::Period was returning a nil ruby value.

### 0.7.5 - 3 August 2009

- Fixes  
http://rick\_denatale.lighthouseapp.com/projects/30941/tickets/19  
Microsoft ical exports double quote tzid values in parameters,  
which caused a failure to find VTIMEZONES  
This exposed an issue with parameter parsing. Did the simplest  
thing which could work which was to  
strip the quotes. Need to BOLO for other pathological cases  
showing up in future, which may require  
smarter parameter parsing.

### 0.7.4 - 21 July 2009

- Fixes  
http://rick\_denatale.lighthouseapp.com/projects/30941/tickets/17

http://rick\_denatale.lighthouseapp.com/projects/30941/tickets/14  
component without recurrence properties should enumerate just

- added the :overlapping option to OccurrenceEnumerator#occurrences
- Allows the enumeration of occurrences which are either partiall or  
completely within a timespan given by a pair of Dates/Times/DateTimes
  - Fixes some Ruby 1.9 incompatibilities

### 0.6.1 - 6 June 2009

- Fixes problem with file which loads activesupport for the rake  
spec:with\_activesupport task, it now  
requires \>=2.2 instead of \<=2.2 - Thanks to Paul Scott-Murphy for  
finding this.

### 0.6.0 - 5 June 2009

Time for a minor version bump.

- Improved overall enumeration performance bypassing most of the  
effects of the poor performance of Ruby’s DateTime class.
- Added a framework for performance monitoring during development.
- New performance directory with subdirs for code to be monitored  
for performance (subjects)
- New script files:  
script/benchmark\_subject runs a ruby benchmark on one  
performance subject  
script/profile\_subject runs ruby-prof for a subject and puts a  
kcachegrind compatible calltree in the performance\_data directory.
- New rake tasks:  
performance:benchmark runs benchmarks against all subjects in  
the performance directory and produces a consolidated output file in  
performance\_data/benchmarks.out  
performance:profile runs script/profile\_subject against all  
subjects in the performance directory.

### 0.5.3 - 1 June, 2009

- Improved performance of time zone enumeration, TimeZonePeriod now  
caches occurrences
- Added a profiling directory which contains ruby programs which  
benchmark and/or profile performance

### 0.0.8

- Fixes  
http://rick\_denatale.lighthouseapp.com/projects/30941-ri\_cal/tickets/1  
EXDATE and RDATE now pick up the timezone from DateTime, Time, and  
TimeWithZone values
- Fixes  
http://rick\_denatale.lighthouseapp.com/projects/30941/tickets/2  
Missing arithmetic methods in PropertyValue::Date
- Fixes  
http://rick\_denatale.lighthouseapp.com/projects/30941/tickets/3

on enumeration, they now  
will enumerate a single occurrence

### 0.0.7

- Fixes a bug relating to properly recognizing  
ActiveRecord::TimeWithZone
- DATETIME propertyvalues will now return an instance of  
TimeWithZone instead of DateTime when  
activesupport is present, and it is appropriate. See the README for  
details

### 0.0.6

- Added rake tasks to run specs with either the tzinfo gem or  
activesupport (\<=2.2)
- Default rake task now runs both of these

### 0.0.5

- Fixes a bug in occurrence enumeration reported by paulsm on github

### 0.0.4

- Fixes a bug in imported timezones reported by paulsm on github

### 0.0.3

- Added tzid method to Ruby Time and DateTime instances, and to  
ActiveRecord::TimeWithZone if it is defined this method is used to  
determine the desired  
timezone when an instance of one of these classes is given as the  
value of a datetime property. If the tzid is nil then the default  
tzid is used,  
if it is set to :floating then the property will be a floating time.
- Removed the ability to pass an array with a tzid string and a  
date-time since the above made it unnecessary
- The ruby datetime property returned from the ruby\_value method on  
the DateTime property will return an instance of ::DateTime with:  
– The proper utc offset  
– The tzid set to the right tzid
- Made exdate/rdate building possible
- Added a default\_tzid attribute to the Calendar component, if this  
attribute is not set for a particular calendar it will delegate to the  
default set  
for the DateTime property class.
- Added fix patches from
