Functions ¶
Types ¶
type Parser ¶
type Parser struct {
Name string
Stream *tokens.Stream
Config *config.Config
Template *nodes.Template
Statements map[string]StatementParser
Level int8
TemplateParser TemplateParser
}
The parser provides you a comprehensive and easy tool to work with the template document and arguments provided by the user for your custom tag.
The parser works on a token list which will be provided by gonja. A token is a unit you can work with. Tokens are either of type identifier, string, number, keyword, HTML or symbol.
(See Token's documentation for more about tokens)
func NewParser ¶
Creates a new parser to parse tokens. Used inside gonja to parse documents and to provide an easy-to-use parser for tag authors
func (*Parser) Current ¶
Current returns the current token without consuming it and only if it matches one of the given types
func (*Parser) Error ¶
Error produces a nice error message and returns an error-object. The 'token'-argument is optional. If provided, it will take the token's position information. If not provided, it will automatically use the CURRENT token's position information.
func (*Parser) Match ¶
Match returns the CURRENT token if the given type matches. Consumes this token on success.
func (*Parser) ParseExpression ¶
func (p *Parser) ParseExpression() (nodes.Expression, error)
ParseExpression parses an expression with optional filters Nested expression should call this method
func (*Parser) ParseFilter ¶
func (p *Parser) ParseFilter() (*nodes.FilterCall, error)
Filter = IDENT | IDENT ":" FilterArg | IDENT "|" Filter
func (*Parser) ParseFilterExpression ¶
func (p *Parser) ParseFilterExpression(expr nodes.Expression) (nodes.Expression, error)
ParseFilterExpression parses an optionnal filter chain for a node
func (*Parser) ParseLogicalExpression ¶
func (p *Parser) ParseLogicalExpression() (nodes.Expression, error)
func (*Parser) ParseMathPrioritary ¶
func (p *Parser) ParseMathPrioritary() (nodes.Expression, error)
func (*Parser) ParsePower ¶
func (p *Parser) ParsePower() (nodes.Expression, error)
func (*Parser) ParseStatementBlock ¶
func (p *Parser) ParseStatementBlock() (*nodes.StatementBlock, error)
func (*Parser) ParseTest ¶
func (p *Parser) ParseTest(expr nodes.Expression) (nodes.Expression, error)
func (*Parser) ParseVariable ¶
func (p *Parser) ParseVariable() (nodes.Expression, error)
func (*Parser) ParseVariableOrLiteral ¶
func (p *Parser) ParseVariableOrLiteral() (nodes.Expression, error)
IDENT | IDENT.(IDENT|NUMBER)...
