GHC.JS.Syntax

Description

  • Domain and Purpose

    GHC.JS.Syntax defines the Syntax for the JS backend in GHC. It comports with the ECMA-262 although not every production rule of the standard is represented. Code in this module is a fork of JMacro (BSD 3 Clause) by Gershom Bazerman, heavily modified to accomodate GHC's constraints.

  • Strategy

    Nothing fancy in this module, this is a classic deeply embeded AST for JS. We define numerous ADTs and pattern synonyms to make pattern matching and constructing ASTs easier.

  • Consumers

    The entire JS backend consumes this module, e.g., the modules in GHC.StgToJS.*. Please see Make for a module which provides helper functions that use the deeply embedded DSL defined in this module to provide some of the benefits of a shallow embedding.

Synopsis

Deeply embedded JS datatypes

data JStat Source #

JavaScript statements, see the ECMA262 Reference for details

Constructors

DeclStat !Ident !(Maybe JExpr)

Variable declarations: var foo [= e]

ReturnStat JExpr

Return

IfStat JExpr JStat JStat

If

WhileStat Bool JExpr JStat

While, bool is "do" when True

ForInStat Bool Ident JExpr JStat

For-in, bool is "each' when True

SwitchStat JExpr [(JExpr, JStat)] JStat

Switch

TryStat JStat Ident JStat JStat

Try

BlockStat [JStat]

Blocks

ApplStat JExpr [JExpr]

Application

UOpStat JUOp JExpr

Unary operators

AssignStat JExpr JExpr

Binding form: foo = bar

UnsatBlock (IdentSupply JStat)

Unsaturated blocks see pseudoSaturate

LabelStat JsLabel JStat

Statement Labels, makes me nostalgic for qbasic

BreakStat (Maybe JsLabel)

Break

ContinueStat (Maybe JsLabel)

Continue
