What problem does Monte solve? + +E and Python +------------ + +Monte is based on E, a language intended for secure distributed computation. +Monte also incorporates many syntactic ideas from Python, a language designed +for readability and simplicity. The design of Monte incorporates both of these +languages' philosophies, with the goal of supporting environments that are +orders of magnitude more complex than existing systems. + +For a history of E's ideas, see http://www.erights.org/history/index.html + +Networking +---------- + +Unlike many other contemporary programming languages, Monte does not need an +additional networking library to provide solid primitive and high-level +networking operations. This is because Monte was designed to handle networking +as easily as any other kind of input or output. + +Distributed Systems +------------------- + +Monte comes with builtin explicit parallelism suitable for scaling to +arbitrary numbers of processes or machines, and a well-defined concurrency +system that simplifies and streamlines the task of writing event-driven code. + +Monte has one parallel primitive: the **vat**. Vats are objects which +encapsulate an entire Monte runtime and isolate other objects from objects in +other vats. Vats are able to communicate across a variety of gulfs, from +inter-process threads to separate machines on a network. + +Monte also has one concurrent operation. Monte permits messages to be passed +as **eventual sends**. An eventually-sent message will be passed to the target +object at a later time, generating a **promise** which can have more messages +sent to it. Unlike similar mechanisms in Twisted, Node.js, etc., Monte builds +promises and eventual sending directly into the language and runtime, removing +the need for extraneous libraries. + +The Semantics +============= + +Architect's View +---------------- + +Monte programs are a collection of vats, running in one or more processes on +one or more hosts. Vats contain three elements: a stack, a queue, and a heap. +All three contain Monte objects. The queue contains messages to objects in the +heap; messages consist of a verb and may contain objects passed as arguments. +Execution of code in a vat progresses by **turns**; each turn is started by +delivering the next message in the queue to its recipient, which can result in +activation records being placed on the stack and further messages going into +the queue. The turn progresses until the stack is empty. A new turn begins +with the next message on the queue. + +Hacker's View +------------- + +Monte is a pure object-based language in the Smalltalk tradition. All values +are objects and all computation is done by sending messages to objects. +Unlike Smalltalk, Python, Java, etc., objects are not instances of classes. +Unlike Self or JavaScript, objects are not derived from prototypes. Monte +objects are defined via object literal syntax as closures over variable +bindings. Specifically unlike Python, objects don't have attributes, merely +responses to messages. + +Compiler's View +--------------- + +Monte provides both immediate, synchronous calls to methods and eventual, +asynchronous sends to methods. The former provides the usual +subroutine-invocation semantics, whereas the latter enqueues a message to be +delivered in a subsequent vat turn. Monte names for objects are encapsulated +in bindings. + +A Monte name binding consists of a slot and a slot guard. Assignment to names +and accessing names invokes methods on that name's slot. This can be used to +share state between objects, and perform actions on reads from/writes to +names. Slot guards for bindings closed over an object are revealed to +auditors, during auditing. + +Name bindings may have guards, which are given objects and may either accept, +coerce, or reject them. Coercion results in the value produced by the guard +being different from the specimen given. The specimen may be asked to conform +itself to the guard as part of coercion. + +Interface expressions are a tool for creating trivial guards; an object +expression may declare that it implements an interface, and the interface +object may be used as a guard to accept only objects that declare that +interface. + +Network's View +-------------- + +This is a big topic and you should read +http://www.erights.org/elib/concurrency/refmech.html for now.

Strings +are also iterable, yielding characters. + +Patterns +======== + +``for`` loops are pattern-based, so arbitrary patterns are permitted in +loops:: + + for some`$sort of @pattern` in iterable: + useThat(pattern) + +Pair Syntax and Keys +==================== + +Unlike other languages, Monte iteration always produces a pair of objects at a +time, called the **key** and **value**. A bit of syntax enables +pattern-matching on the key:: + + for key => value in iterable: + traceln(key) + traceln(value) + +As expected, the key for iteration on a map is the key in the map +corresponding to each value. The key for iteration on lists and strings is the +zero-based index of each item or character. + +It is possible to iterate only over the keys, of course, using an ignore +pattern:: + + for key => _ in iterable: + traceln(key) + +Loops as Expressions +==================== + +Like all structures in Monte, ``for`` loops are expressions, which means that +they can return values and be used where other expressions are used. + +A ``for`` loop usually returns ``null``:: + + def result := for value in 0..10 { value } + +Here, ``result`` is ``null``. + +However, a ``for`` loop can return another value with the ``break`` keyword:: + + def result := for value in 0..10 { break value } + +Since ``break`` was used, the loop exits on its first iteration, returning +``value``, which was ``0``. So ``result`` is ``0``. + +.. note:: + + The syntax of ``break`` permits parentheses around the return value, like + ``break(this)``, and also an empty pair of parentheses to indicate a null + return value, like so: ``break()``. + +Comprehensions +============== + +``for`` loops aren't the only way to consume iterable objects. Monte also has +**comprehensions**, which generate new collections from iterables:: + + [transform(value) for value in iterable] + +This will build and return a list. Maps can also be built with pair syntax:: + + [key => makeValue(key) for key in keyList] + +And, of course, pair syntax can be used for both the pattern and expression in +a comprehension:: + + [value => key for key => value in reverseMap] + +Comprehensions also support *filtering* by a condition. The conditional +expression is called a **predicate** and should return ``true`` or ``false``, +depenting on whether the current value should be *skipped*. For example, let's +generate a list of even numbers:: + + def evens := [number for number in 0..20 if number % 2 == 0] + +Unlike many other languages, the predicate must return a Boolean value; if it +doesn't, then the entire comprehension will fail with an exception. + +Writing Your Own Iterables +========================== + +Monte has an iteration protocol which defines iterable and iterator objects. +By implementing this protocol, it is possible for user-created objects to be +used in ``for`` loops and comprehensions. + +Iterables need to have ``to _makeIterator()``, which returns an iterator. +Iterators need to have ``to next(ej)``, which takes an ejector and either +returns a list of ``[key, value]`` or fires the ejector with any value to end +iteration. Guards do not matter but can be helpful for clarity. + +As an example, let's look at an iterable that counts upward from zero to +infinity:: + + object countingIterable: + to _makeIterator(): + var i := 0 + return object counter: + to next(_): + def rv := [i, i] + i += 1 + return rv + +Since the iterators ignore their ejectors, iteration will never terminate. + +For another example, let's look at an iterator that wraps another iterator and +only lets even values through:: + + def onlyEvens(iterator): + return object evens: + to next(ej): + var rv := iterator.next(ej) + while (rv[1] % 2 != 0): + rv := iterator.next(ej) + return rv + +Note that the ejector is threaded through ``to next(ej)`` into the inner +iterator in order to allow iteration to terminate if/when the inner iterator +becomes exhausted.

The +paradigm is known as *tubes*. + +Tubes come in two flavors: *founts* and *drains*. A fount is an object which +can provide data to another tube. A drain is an object which can receive data +from another tube. A tube can be just a fount, just a drain, or both a fount +and a drain. + +This is all pretty abstract. Let's roll up our sleeves and take a look at how +to use some tubes:: + + def echo(fount, drain): + fount.flowTo(drain) + +This code instructs ``fount`` to provide data to ``drain``. This providing of +data will happen whenever ``fount`` wants, until either ``fount`` or ``drain`` +indicate that flow should cease. While this example might seem trivial, it's +sufficient to use as e.g. a TCP echo server. + +Sometimes founts receive their data between turns, and schedule special turns +to send data to drains. Other times founts are eager, and try to feed a drain +immediately during ``flowTo``. If you want to forcibly delay that eagerness +until another turn, just use an eventual send:: + + def echo(fount, drain): + fount<-flowTo(drain) + +If a drain is also a fount, then ``flowTo`` will return a new fount which can +be flowed to another drain.
