Adding\n * wildcards will increase the number of documents that will be found but can also have a negative\n * impact on query performance, especially with wildcards at the beginning of a term.\n *\n * Terms can be restricted to specific fields, e.g. `title:hello`, only documents with the term\n * hello in the title field will match this query.

Edit distance is also supported\n * to provide fuzzy matching, e.g. 'hello~2' will match documents with hello with an edit distance of 2.\n * Avoid large values for edit distance to improve query performance.\n *\n * Each term also supports a presence modifier. By default a term's presence in document is optional, however\n * this can be changed to either required or prohibited. For a term's presence to be required in a document the\n * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and\n * optionally contain 'bar'.

    The client for remote calendars with builtin cache support

    +

    When you have a service that periodically runs, and you don't want to fetch a new version of your calendar each time, this is the go-to place.

    + + +
    + + + +

    + CacheClient + + +

    + + +
    + + +

    NameTypeDescriptionDefault
    cache_location + Union[Path, str] + +
    +

    A path to the cache. Can be relative or absolute references. When you pass in a value with a file extension, it is considered to be a directory, otherwise it's considered as a file reference.

    +
    +
    + required +
    cache_ttl + Union[Duration] + +
    +

    The time-to-live for the cache. The cache will be deleted/refreshed once it is older than the TTL.

    +
    +
    + Duration(hours=1) +
    verbose + bool + +
    +

    Print verbose messages regarding cache usage.

    +

    Documentation for your first returned item: VCalendar

    +

    Once you imported the iCal-library library, you can use either the client or CacheCLient to get a VCalendar object. +This page explains all the functions and attributes of the VCalendar object.

    + + +
    + + + +

    + VCalendar + + +

    + + +
    +

    + Bases: Component

    + + +

    This class represents the VCALENDAR component specified in RFC 5545 in '3.6. Calendar Components'.

    +

    The "VCALENDAR" component consists of a sequence of calendar properties and one or more calendar components. +The calendar properties are attributes that apply to the calendar object as a whole. The calendar components are +collections of properties that express a particular calendar semantic. For example, the calendar component can +specify an event, a to-do, a journal entry, time zone information, free/busy time information, or an alarm.

    + + + +

    Parameters:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    + Component + + +

    + + +
    +

    + Bases: ICalBaseClass

    + + +

    This is the base class for any component (according to the RFC 5545 specification) in iCal-library.

    +

    Inside all components (so also all classes inheriting this class, e.g. VEvent) there are four kind of variables:

    +
      +
    • variables that start with _. These are metadata of the class and not parsed as a property or + component from the iCalendar data file.
    • +
    • variables that have a type of List[x] and a default value of List. These are child components/properties of +the instance. These components/properties may or may not be required to be present in the iCal file.
    • +
    • variables that have a type of Optional[List[x]]. These are components/properties of the instance. +They can be either optional or required and may occur multiple times in the iCal file.
    • +
    • variables that have a type of Optional[x] (and not Optional[List[x]]). These are properties of the instance. +They can be either optional or required, but may only occur once in the iCal file.
    • +
    +

    Any Component that is predefined according to the RFC 5545 should inherit this class, e.g. VCalendar, VEVENT. +Only x-components or iana-components should instantiate the Component class directly.

    + + + +

    Parameters:

    + + + + + + + + + + + + + + + + + + + + + + + +
    NameTypeDescriptionDefault
    name + str + +
    +

    The actual name of this component instance. E.g. VEVENT, RRULE, VCUSTOMCOMPONENT.

    +
    +
    + required +
    parent + Optional[Component] + +
    +

    The Component this item is encapsulated by in the iCalendar data file.

    All Components

    +

    If you haven't already, first check out Component over at base classes. +These are part of the components you can encounter in a iCalendar data file. The others are mentioned in Recurring components and Timezone components.

    +

    Simple components

    +

    We start out with the components that are relatively straight forward. There is no recurring option here.

    + + +
    + + + +

    + VFreeBusy + + +

    + + +
    +

    + Bases: Component

    + + +

    This class represents the VFREEBUSY component specified in RFC 5545 in '3.6.4. Free/Busy Component'.

    +

    A "VFREEBUSY" calendar component is a grouping of component properties that represents either a request for free +or busy time information, a reply to a request for free or busy time information, or a published set of busy time +information.

    + + + +

    Parameters:

    Recurring components

    +

    These are the components that have the possibility to be recurring. For each of them there is their standard class and their recurring class. The idea is that the original definition is represented by the standard class and any occurrence that is generated based on the recurring properties, is represented by the recurring class.

    +

    Given all classes that have recurring options have a major overlap, there are two class abstracting the complexity away from them. This is again in the same concept, where the first one covers the standard class, and the other one covers the recurring class. These two are listed here first before the rest.

    + + +
    + + + +

    + AbstractComponentWithRecurringProperties + + +

    + + +
    +

    + Bases: Component, ABC

    + + +

    This class helps avoid code repetition with different :class:Component classes that have a duration and have +recurring properties.

    +

    This class is inherited by VEvent, VToDo and VJournal as these all have recurring properties like :class:RRule, +:class:RDate and :class:EXDate. All properties they had in common are part of this class. +Note: VJournal is the odd one out as these events don't have a duration.

    + + + +

    Parameters:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    +
    + +
    + +
    + + + +

    + parent: Component + + + property + + +

    + + +
    + +

    Return the parent of the original component.

    + Bases: AbstractComponentWithRecurringProperties

    + + +

    This class represents the VEVENT component specified in RFC 5545 in '3.6.1. Event Component'.

    +

    A "VEVENT" calendar component is a grouping of component properties, possibly including "VALARM" calendar +components, that represents a scheduled amount of time on a calendar. For example, it can be an activity; such as +a one-hour long, department meeting from 8:00 AM to 9:00 AM, tomorrow. Generally, an event will take up time on an +individual calendar. Hence, the event will appear as an opaque interval in a search for busy time. Alternately, +the event can have its Time Transparency set to "TRANSPARENT" in order to prevent blocking of the event in +searches for busy time.

    + + + +

    Parameters:

    + + +
    +

    + Bases: AbstractComponentWithRecurringProperties

    + + +

    This class represents the VJOURNAL component specified in RFC 5545 in '3.6.3. Journal Component'.

    +

    A "VJOURNAL" calendar component is a grouping of component properties that represent one or more descriptive text +notes associated with a particular calendar date. The "DTSTART" property is used to specify the calendar date with +which the journal entry is associated. Generally, it will have a DATE value data type, but it can also be used to +specify a DATE-TIME value data type. Examples of a journal entry include a daily record of a legislative body or +a journal entry of individual telephone contacts for the day or an ordered list of accomplishments for the day. +The "VJOURNAL" calendar component can also be used to associate a document with a calendar date.

    + + + +

    Parameters:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    NameTypeDescriptionDefault

    The actual name of this component instance. E.g. VEVENT, RRULE, VCUSTOMCOMPONENT.

    +
    +
    + required +
    dtstamp + Optional[DTStamp] + +
    +

    The DTStamp property. Required and must occur exactly once.

    +
    +    A "VJOURNAL" calendar component is a grouping of component properties that represent one or more descriptive text
    +    notes associated with a particular calendar date. The "DTSTART" property is used to specify the calendar date with
    +    which the journal entry is associated. Generally, it will have a DATE value data type, but it can also be used to
    +    specify a DATE-TIME value data type. Examples of a journal entry include a daily record of a legislative body or
    +    a journal entry of individual telephone contacts for the day or an ordered list of accomplishments for the day.
    +    The "VJOURNAL" calendar component can also be used to associate a document with a calendar date.

    Timezone components

    +

    These are the components that are related to TimeZone information. You generally don't use these directly but let iCal-library use it when there is a TZID parameter set for a property.

    +

    The DayLight and Standard class both extend the _TimeOffsetPeriod.

    + + +
    + + + +

    + VTimeZone + + +

    + + +
    +

    + Bases: Component

    + + +

    This class represents the VTIMEZONE component specified in RFC 5545 in '3.6.5. Time Zone Component'.

    +

    If present, the "VTIMEZONE" calendar component defines the set of Standard Time and Daylight Saving Time +observances (or rules) for a particular time zone for a given interval of time. The "VTIMEZONE" calendar component +cannot be nested within other calendar components. Multiple "VTIMEZONE" calendar components can exist in an +iCalendar object. In this situation, each "VTIMEZONE" MUST represent a unique time zone definition. This is +necessary for some classes of events, such as airline flights, that start in one time zone and end in another.

    + + + +

    Parameters:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    NameTypeDescriptionDefault
    parent + Optional[Component] + +
    +

    The Component this item is encapsulated by in the iCalendar data file.

    +
    +
    + None +
    tzid + Optional[TZID] + +
    +

    The TZID property. Required and must occur exactly once.

    +
    +
    + None +
    last_mod + Optional[LastModified] + +
    +

    Optional LastModified property. Optional, but may occur at most once.

    +
    +
    + None +
    tzurl + Optional[TZURL] + +
    +

    The TZURL property. Optional, but may occur at most once.

    +
    +
    + None +
    standardc + Optional[List[Standard]] + +
    +

    Optional list of Standard components. Each component may occur multiple times. Either standardc or daylightc must contain at least one TimeOffsetPeriod.

    +
    +
    + None +
    daylightc + Optional[List[DayLight]] + +
    +

    Optional list of DayLight components. Each component may occur multiple times. Either standardc or daylightc must contain at least one TimeOffsetPeriod.

    Property base class

    +

    All Properties are extending the Property class. Let's first start with the base class and then list all the other properties.

    + + +
    + + + +

    + Property + + +

    + + +
    +

    + Bases: ICalBaseClass

    + + +

    This is the base class for any property (according to the RFC 5545 specification) in iCal-library.

    +

    A property always exists of three parts:

    +
      +
    • The name of the property.
    • +
    • The property parameters, this is optional and does not need to be present.
    • +
    • The value of the property.
    • +
    +

    A line containing a property typically has the following format: +PROPERTY-NAME;parameterKey=parameterValue,anotherParameterKey=anotherValue:actual-value

    +

    Any property that is predefined according to the RFC 5545 should inherit this class, e.g. UID, RRule. +Only x-properties or iana-properties should instantiate the Property class directly.

    + + + +

    Parameters:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    NameTypeDescriptionDefault
    value + Optional[str] + +
    +

    The value of the property.

    +
    +
    + required +
    name + Optional[str] + +
    +

    The properties name, e.g. RRULE.

    +
    +
    + None +
    property_parameters + Optional[str] + +
    +

    The property parameters for this definition.

    +
    +
    + None +
    parent + Component + +
    +

    Instance of the :class:Component it is a part of.

    This is the list of all help classes.

    All Properties

    +

    All Properties are extending the Property class. Let's first start with the base class and then list all the other properties.

    + + +
    + + + +

    + Property + + +

    + + +
    +

    + Bases: ICalBaseClass

    + + +

    This is the base class for any property (according to the RFC 5545 specification) in iCal-library.

    +

    A property always exists of three parts:

    +
      +
    • The name of the property.
    • +
    • The property parameters, this is optional and does not need to be present.
    • +
    • The value of the property.
    • +
    +

    A line containing a property typically has the following format: +PROPERTY-NAME;parameterKey=parameterValue,anotherParameterKey=anotherValue:actual-value

    +

    Any property that is predefined according to the RFC 5545 should inherit this class, e.g. UID, RRule. +Only x-properties or iana-properties should instantiate the Property class directly.

    + + + +

    Parameters:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    NameTypeDescriptionDefault
    value + Optional[str] + +
    +

    The value of the property.

    +
    +
    + required +
    name + Optional[str] + +
    +

    The properties name, e.g. RRULE.

    +
    +
    + None +
    property_parameters + Optional[str] + +
    +

    The property parameters for this definition.

    +
    +
    + None +
    parent + Component + +
    +

    Instance of the :class:Component it is a part of.

    +
    +
    + None +

    Documentation for the Timeline

    +

    From the VCalendar it is very easy to create a Timeline object. This will show you all the components you have in a specific time frame.

    + + +
    + + + +

    + Timeline + + +

    + + +
    + + +

    This class is a wrapper to make it easy to see what the order of each component based on the start date.

    +

    Inside this class there are multiple methods to iterate over all the components present. However, one should note +that often the recurrence properties for components specify only a lower bound and will therefore proceed to +infinity. To prevent us having an infinite list of items to iterate on, we define upper and lower bounds. +You should set these upper bounds to the absolute minimum start date and absolute maximum end date that you would +ever need. So if you need to do 10 different queries, this start and end date should range all of these, so it +doesn't need to compute the list of components in the range over and over again. The functions themselves(e.g. +:function:self.includes and :function:self.intersects) help you to limit the exact range you want to return +components for.

    FAQ

    +
    +Why did you create this library and not use one of the existing libraries? +

    I first tried several libraries for iCalendar events. However, none of them supported recurring events as well as they should be. For some libraries my calendar loaded but then didn't show my recurring events, while others simply threw stacktraces trying to load it. Furthermore, I noticed that my calendar (with over 2000 events) took ages to load. +After traversing the code of the other libraries I decided I wanted to build my own. With some key principles that were lacking in most of the libraries:

    +
      +
    • Recurring components should work, always, FOREVER.
    • +
    • No strict evaluation that could lead to errors while parsing the file.
    • +
    • Lazy evaluation for iCalendar properties to speed up the process.
    • +
    • Perfect typing information.
    • +
    • Striving for no open issues & especially no open pull requests that are waiting for feedback!

    Source Code: https://github.com/Jorricks/iCal-library

    +
    +

    iCal-library is a Python library for anyone who wishes to read any iCalendar file.

    +

    It is one of the fastest iCalender python library out there and has excellent support for recurring events. Now there is truly no reason to miss an event, ever.

    +
    +

    This project is under active development.

    +

    You may encounter items on which we can improve, please file an issue if you encounter any issue or create a feature request for any missing feature.

    +
    +

    Features

    +
      +
    • 🚀 Easy python interface. It's as simple as 'client.load_ics_file("<my_file>").timeline' to show all your events of that week.
    • +
    • 📈 Timeline support. Show exactly what is planned for a specific week.
    • +
    • Fully functional support for recurring iCal components. E.g. Any recurring event will show up as intended within the timeline interface. This includes:
        +
      1. Recurring components/events based on RRule.
      2. +
      3. Recurring components/events based on RDate.
      4. +
      5. Excluding components/events based on EXDate.
      6. +
      7. Any combination of the above three.
      8. +
      9. Redefined/changed components/events correctly show the latest version.
      10. +
      +
    • +
    • ⏩ Very fast parsing due to lazy evaluation of iCal properties.
    • +
    • ⁉️ Debugger supported. Any issues? Open up a debugger and inspect all values.
    • +
    • 🔅 Minimal dependencies. Only python-dateutil and pendulum.
    • +
    • 🆎 Fully typed code base.
    • +
    +

    Installation

    +

    To use iCal-library, first install it using pip:

    +
    pip install iCal-libraryInstalled
    + +

    Requirements

    +

    Python 3.8+

    +

    iCal-library uses two major libraries for their date and time utilities: +- Pendulum for its extensions on datetime objects and parsing of durations. +- Python-Dateutil for its RRule support.

    +

    Example

    +

    A simple example. Please look in the docs for more examples.

    +
    from ical_library import client
    +
    +calendar = client.parse_icalendar_file("/home/user/my_icalendar.ics")
    +print(calendar.events)
    +print(calendar.todos)
    +print(calendar.journals)
    +print(calendar.free_busy_list)
    +print(calendar.time_zones)
    +
    +
    +During experimentation, it is recommended to use a Python Debugger. +

    iCal-library is fully Debugger compliant, meaning it is very easy to use a debugger with this project. It will be much faster to see all the different attributes and functions from inside a Python debugger. If you are unsure whether your IDE supports it, take a look here under the sections 'IDEs with Debug Capabilities'.

    +
    +

    Limitations

    +
      +
    • Currently, it is not supported to write ICS files. If this is a deal-breaker for you, it should be relatively straight forward to add it, so please consider submitting a PR for this :).

    Release Notes

    +

    0.2.3 Pendulum pinning

    +

    This version is there to pin the pendulum version. Two changes: +- 📌 Pin pendulum to <3.0.0 +- ✅ Update tests for compatibility with different timezones

    +

    0.2.2 BugFix release

    +

    This is a minor release to solve a critical bug. +It occurred when it is expanding a recurring event with a start date in dates for a range defined by dates. +- 🐛 RRule expansion failing where event.start_date==return_range.start.

    +

    0.2.1 Documentation update

    +

    A minor update to improve documentation: +- 📝 Remove workflow badge +- ⬆️ Add Python 3.11 & 3.12 support

    +

    0.2.0 Release to improve timezone offset changes support

    +

    This release contains some bugfixes and a major improvement to also support timezone offset changes over time. +Thereby, recurring events for timezones that have Daylight saving time now correctly change according to the VTIMEZONE definition. +Furthermore, EXDATE (so excluding a single occurrence from a recurring event) now correctly handles timezones. Previously it did not exclude EXDATE's with a Timezone correctly. This release fixes that.

    +
      +
    • ✨ Support offset changes in a sequence of recurring events.
    • +
    • 🐛 Return only recurring items in Timespan range.
    • +

    Remote iCalendars

    +

    Here are some more in-depth use-cases

    +

    Integration status.

    +
      +
    • Google Calendar: . Works with private and public calendars. Also works when you are part of an organisation that does not allow plugins.
    • +
    • Microsoft Outlook: . Requires you to make your calendar public.
    • +
    • Apple Calendar: . Unable to find any info on how to make calendars public.
    • +
    +

    Getting the iCalendar URL for remote calendars.

    +

    Before we can actually load in the data of your calendar, we need to get the iCalendar URL. +The steps are different per host, some of them are listed here:

    + +
    +

    Info

    +

    This package is actively tested with Google iCalendars. +If you have any other calendars and encounter odd behaviour, please file a Github feature request or a Github Issue.

    +
    +

    Reading your iCalendar from a remote place

    +
      +
    1. Follow one of the above-mentioned tutorial to get the iCalendar URL.
    2. +
    3. Verify that when you open the URL in your browser, it shows a page or downloads a file that begins with BEGIN:VCALENDAR.
    4. +
    5. Use the client.parse_icalendar_url() to get it directly.
    6. +
    +
    from ical_library import client
    +
    +calendar = client.parse_icalendar_url("https://calendar.google.com/calendar/ical/xxxxxx/private-xxxxxx/basic.ics")
    +print(calendar.events)
    +
    +

    Reading your iCalendar from a remote place with rate limiting

    +

    To help you avoid doing unnecessary requests to your iCalendar provider, there is a CacheClient. +This helps you cache the result on a location on your Hard Drive to avoid the need to fetch it every time you restart +your application.

    +
    from pathlib import Path
    +from pendulum import Duration
    +from ical_library.cache_client import CacheClient
    +
    +cache_client = CacheClient(
    +    url="https://calendar.google.com/calendar/ical/xxxxxx/private-xxxxxx/basic.ics",
    +    cache_location=Path.home() / "ical-library-cache",
    +    cache_ttl=Duration(hours=1),
    +    verbose=True,
    +)
    +calendar = cache_client.get_icalendar()
    +print(calendar.events)
    +
    +
    +

    Info

    +

    If you have a production use-case for a 24/7 running service, you might be better of doing the caching/rate-limiting +in your service.

Thereby, recurring events for timezones that have Daylight saving time now correctly change according to the VTIMEZONE definition. Furthermore, EXDATE (so excluding a single occurrence from a recurring event) now correctly handles timezones. Previously it did not exclude EXDATE's with a Timezone correctly.

This page explains all the functions and attributes of the VCalendar object. VCalendar Bases: Component This class represents the VCALENDAR component specified in RFC 5545 in '3.6. Calendar Components'. The \"VCALENDAR\" component consists of a sequence of calendar properties and one or more calendar components. The calendar properties are attributes that apply to the calendar object as a whole. The calendar components are collections of properties that express a particular calendar semantic. For example, the calendar component can specify an event, a to-do, a journal entry, time zone information, free/busy time information, or an alarm. Parameters: Name Type Description Default prodid Optional [ ProdID ] The ProdID property. Required and must occur exactly once. None version Optional [ Version ] The Version property. Required and must occur exactly once. None calscale Optional [ CalScale ] The CalScale property. Optional, but may occur at most once. None method Optional [ Method ] The Method property.

Inside this class there are multiple methods to iterate over all the components present. However, one should note that often the recurrence properties for components specify only a lower bound and will therefore proceed to infinity. To prevent us having an infinite list of items to iterate on, we define upper and lower bounds. You should set these upper bounds to the absolute minimum start date and absolute maximum end date that you would ever need. So if you need to do 10 different queries, this start and end date should range all of these, so it doesn't need to compute the list of components in the range over and over again. The functions themselves(e.g. :function:`self.includes` and :function:`self.intersects`) help you to limit the exact range you want to return components for. :param v_calendar: The VCalendar object we are iterating over. :param start_date: The minimum ending date of each event that is returned inside this timeline. :param end_date: The maximum starting date of each event that is return inside this timeline. \"\"\" def __init__ ( self , v_calendar : VCalendar , start_date : Optional [ DateTime ] = None , end_date : Optional [ DateTime ] = None ): self . v_calendar : VCalendar = v_calendar self . _start_date : DateTime = start_date or DateTime ( 1970 , 1 , 1 ) self . _end_date : DateTime = end_date or DateTime ( 2100 , 1 , 1 ) def __repr__ ( self ) -> str : return f \"Timeline( { self . _start_date } , { self . _end_date } )\" @property def start_date ( self ) -> DateTime : \"\"\"Return the start date of the timeline.

Event Component'. A \"VEVENT\" calendar component is a grouping of component properties, possibly including \"VALARM\" calendar components, that represents a scheduled amount of time on a calendar. For example, it can be an activity; such as a one-hour long, department meeting from 8:00 AM to 9:00 AM, tomorrow. Generally, an event will take up time on an individual calendar. Hence, the event will appear as an opaque interval in a search for busy time. Alternately, the event can have its Time Transparency set to \"TRANSPARENT\" in order to prevent blocking of the event in searches for busy time. :param name: The actual name of this component instance.
