Usage​

import salix::Core;

Source code​

Dependencies​

import salix::Node;
import List;
import String;
import IO;
import lang::json::IO;

data Handle​

data Handle  
     = handle(int id, list[int] maps = [])
     ;

Handles represent (encoded) functions to decode events. id: identifies the decoder function (e.g., of type Msg(int)) maps: identifies the active mappers for this handle.

alias Encoding​

tuple[int id, map[int, value] from, map[value, int] to, map[int, value] closures]

function switchTo​

void switchTo(str appId)

function switchFrom​

void switchFrom(str appId)

function _encode​

int _encode(value x)

function _partial​

&T(&V) _partial(list[value] key, &T(&V) closure)

function partial​

&T(&V) partial(&T(&U0, &V) f, &U0 u0)

&T(&V) partial(&T(&U0, &U1, &V) f, &U0 u0, &U1 u1)

&T(&V) partial(&T(&U0, &U1, &U2, &V) f, &U0 u0, &U1 u1, &U2 u2)

&T(&V) partial(&T(&U0, &U1, &U2, &U3, &V) f, &U0 u0, &U1 u1, &U2 u2, &U3 u3)

function _decode​

&U _decode(int funcId, type[&U] _)

default &U _decode(int funcId, type[&U] _)

function encode​

Handle encode(value x)

function decode​

&T decode(Handle h, type[&T] t)

&T decode(int funcId, type[&T] t)

function printNodeStack​

void printNodeStack()

Print out the current node stack for debugging.

function add​

void add(Node h)

Basic stack management functions.

function addNode​

void addNode(Node h)

function push​

void push(list[Node] l)

function top​

list[Node] top()

function pop​

list[Node] pop()

function initialize​

tuple[list[Cmd], &T] initialize(&T() init, void(&T) view)

Initialize viewContext for an initial model, so that cmds are properly mapped.

function render​

Node render(&T model, void(&T) block)

Node render(void() block)

Render turns void returning views for a model &T into an Node node.

function withExtra​

void withExtra(map[str, value] stuff, void() block)

function build​

void build(list[value] vals, str tagName)

The basic build function to construct html elements on the stack. The list of argument values can contain any number of Attr values. The last argument (if any) can be a blouitck, an Node node, or a value. In the latter case it is converted to a txt node.

function _text​

void _text(value v)

Create a text node from an arbitrary value.

data Sub​

data Sub  
     = subscription(str name, Handle handle, map[str, value] args = ())
     ;

Subs are like events: they are sent to JS, and messages are sent back.

function timeEvery​

Sub timeEvery(Msg(int) int2msg, int interval)

Smart constructors for constructing encoded subscriptions.

alias Subs​

list[Sub](&T)

function noSubs​

list[Sub] noSubs(&T _)

data Cmd​

data Cmd  
     = command(str name, Handle handle, map[str,value] args = ())
     ;

Commands represent actions that need to be performed at the client.

function do​

void do(Cmd cmd)

function execute​

tuple[list[Cmd], &T] execute(Msg msg, &T(Msg, &T) update, &T model)

tuple[list[Cmd], &T] execute(&T() init)

function random​

Cmd random(Msg(int) f, int from, int to)

Smart constructors for constructing encoded commands.

function setFocus​

Cmd setFocus(Msg() f, str id)

data Hnd​

data Hnd  
     = handler(str name, Handle handle, map[str,value] args = ())
     ;

alias Parser​

Msg(str,Handle,map[str,value])
