Documentation
Arguments
| :: String | The input stream (Javascript source code). |
| -> String | The name of the Javascript source (filename or input device). |
| -> Either ParseError JSNode | An error or maybe the abstract syntax tree (AST) of zero or more Javascript statements, plus comments. |
Parse one compound statement, or a sequence of simple statements. Generally used for interactive input, such as from the command line of an interpreter. Return comments in addition to the parsed statements.
showStripped :: JSNode -> StringSource
Source location spanning a contiguous section of a file.
Constructors
| SpanCoLinear | A span which starts and ends on the same line. |
Fields
| |
| SpanMultiLine | A span which starts and ends on different lines. |
Fields
| |
| SpanPoint | A span which is actually just one point in the file. |
Fields
| |
| SpanEmpty | No span information. |
Constructors
data ParseError Source
Constructors
| UnexpectedToken Token | An error from the parser. Token found where it should not be. Note: tokens contain their own source span. |
| UnexpectedChar Char AlexPosn | An error from the lexer. Character found where it should not be. |
| StrError String | A generic error containing a string message. No source location. |
Instances
Posn records the location of a token in the input text. It has three
fields: the address (number of characters preceding the token), line number
and column of a token within the file. start_pos gives the position of the
start of the file and eof_pos a standard encoding for the end of file.
move_pos calculates the new position after traversing a given character,
assuming the usual eight character tab stops.
