When we started planning Summer Reading, we were still in Covid-19 lockdown mode. Reader Zone had features we appreciated. That it was affordable was icing on the cake!
Our experiment with Reader Zone was successful. We extended our subscription to add more challenges and contests for readers of all ages.
We introduced the app to our patrons on social media and through our paper Summer Reading information. We also created a short video to explain how to sign into the app and use its features. We wanted to make this as simple and stress-free as possible, and this helped to flatten out the learning curve. Once they got the hang of it, our community really took to it! We saw an almost 50% increase in the number of adults participating in Summer Reading, and for kids, we saw an uptick in completion rates. Overall, we felt that our Summer Reading experiment with Reader Zone was successful, and we extended our subscription to add more challenges and contests for readers of all ages through the next year.
That said, most Clojure programs begin life as text files, and it is the task of the reader to parse the text and produce the data structure the compiler will see. This is not merely a phase of the compiler. The reader, and the Clojure data representations, have utility on their own in many of the same contexts one might use XML or JSON etc.
One might say the reader has syntax defined in terms of characters, and the Clojure language has syntax defined in terms of symbols, lists, vectors, maps etc. The reader is represented by the function read, which reads the next form (not character) from a stream, and returns the object represented by that form.
Since we have to start somewhere, this reference starts where evaluation starts, with the reader forms. This will inevitably entail talking about data structures whose descriptive details, and interpretation by the compiler, will follow.
The behavior of the reader is driven by a combination of built-in constructs and an extension system called the read table. Entries in the read table provide mappings from certain characters, called macro characters, to specific reading behavior, called reader macros. Unless indicated otherwise, macro characters cannot be used in user symbols.
Metadata is a map associated with some kinds of objects: Symbols, Lists, Vector, Sets, Maps, tagged literals returning an IMeta, and record, type, and constructor calls. The metadata reader macro first reads the metadata and attaches it to the next form read (see with-meta to attach meta to an object):
^:a 1 :b 2 [1 2 3] yields the vector [1 2 3] with a metadata map of :a 1 :b 2.
The key in each pair is a tag that will be recognized by the Clojure reader. The value in the pair is the fully-qualified name of a Var which will be invoked by the reader to parse the form following the tag. For example, given the data_readers.clj file above, the Clojure reader would parse this form:
by invoking the Var #'my.project.foo/bar on the vector [1 2 3]. The data reader function is invoked on the form AFTER it has been read as a normal Clojure data structure by the reader. For your own data reader functions, you should report errors by throwing instances of RuntimeException with messages providing error information.
Reader tags without namespace qualifiers are reserved for Clojure. Default reader tags are defined in default-data-readers but may be overridden in data_readers.clj / data_readers.cljc or by rebinding *data-readers*. If no data reader is found for a tag, the function bound in *default-data-reader-fn* will be invoked with the tag and value to produce a value. If *default-data-reader-fn* is nil (the default), a RuntimeException will be thrown.
Clojure 1.4 introduced the instant and UUID tagged literals. Instants have the format #inst "yyyy-mm-ddThh:mm:ss.fff+hh:mm".NOTE: Some of the elements of this format are optional. See the code for details.The default reader will parse the supplied string into a java.util.Date by default. For example:
Since *data-readers* is a dynamic var that can be bound, you can replace the default reader with a different one. For example, clojure.instant/read-instant-calendar will parse the literal into a java.util.Calendar, while clojure.instant/read-instant-timestamp will parse it into a java.util.Timestamp:
If no data reader is found when reading a tagged literal, the *default-data-reader-fn* is invoked. You can set your own default data reader function and the provided tagged-literal function can be used to build an object that can store an unhandled literal. The object returned by tagged-literal supports keyword lookup of the :tag and :form:
In cases where is not feasible to isolate the varying parts of the code, or where the code is mostly portable with only small platform-specific parts, 1.7 also introduced reader conditionals, which are supported only in cljc files and at the default REPL. Reader conditionals should be used sparingly and only when necessary.
The syntax for #?@ is exactly the same but the expression is expected to return a collection that can be spliced into the surrounding context, similar to unquote-splicing in syntax quote. Use of reader conditional splicing at the top level is not supported and will throw an exception. An example:
The read and read-string functions optionally take a map of options as a first argument. The current feature set and reader conditional behavior can be set in the options map with these keys and values:
If the reader is invoked with :read-cond :preserve, the reader conditional and non-executed branches will be preserved, as data, in the returned form. The reader-conditional will be returned as a type that supports keyword retrieval for keys with :form and a :splicing? flag. Read but skipped tagged literals will be returned as a type that supports keyword retrieval for keys with :form and :tag keys.
Write implements the standard Write interface:it writes data to the pipe, blocking until one or more readershave consumed all the data or the read end is closed.If the read end is closed with an error, that err isreturned as err; otherwise err is ErrClosedPipe.
MultiReader returns a Reader that's the logical concatenation ofthe provided input readers. They're read sequentially. Once allinputs have returned EOF, Read will return EOF. If any of the readersreturn a non-nil, non-EOF error, Read will return that error.

When used as a standalone reader, it enables the user to read any file from the SD card. These could be BRF and BRL formatted books, text files or files in any format. This allows students, especially in developing countries, to have content loaded on to the SD card by teachers and use the unit without any live connectivity to a computer or the internet. The reader has features for easy navigation, inserting and editing bookmarks, browsing through folders, etc.
As a braille display, the Orbit Reader connects to PCs and Macs, iOS devices and Android devices. It provides Bluetooth and USB connectivity and can connect simultaneously to multiple devices. Using the screen reading capability on the computing device, such as Voiceover, Brailleback or popular PC screen readers the user can control the functions of their computer or smartphone, use their favourite apps, read and send text messages and email and browse the internet.
While it offers a host of features, the Orbit Reader 20 is extremely easy to use and allows seamless and instantaneous switching between reader, note-taker and braille display modes, as well as selection between connected devices such as a computer or phone.
Note: Apps that let people access digital content such as music or video, but not as the primary functionality, are not considered reader apps and are not eligible for the External Link Account Entitlement. For example, a social networking app that lets people stream audiovisual content is not eligible.
In addition to enabling an entitlement for your app and implementing the required External Link Account APIs, you must follow usage requirements designed to help protect privacy and security, prevent scams and fraudulent activity, and maintain the overall quality of the experience. Any link provided in a reader app must:
The External Link Account Entitlement can be used by approved reader apps distributed in any country or region where the App Store is available, and is compatible with devices running iOS and/or iPadOS, or tvOS 16.4 or later.
No. The External Link Account Entitlement is optional and only required for reader apps that wish to link out to a website for account creation and management. Reader apps can continue to offer account creation for free tiers, and account management functionality for existing customers within the app, per guideline 3.1.3(a).
