Types

type Converter 

type Converter struct {

	// UseSpaces disables the default spaceless-mode
	UseSpaces bool
	// contains filtered or unexported fields
}

Converter can convert a nolol-ast to a yolol-ast

func NewConverter 

func NewConverter() *Converter

NewConverter creates a new converter

func (*Converter) Convert 

func (c *Converter) Convert(prog *nast.Program, files FileSystem) (*ast.Program, error)

Convert converts a nolol-program to a yolol-program files is an object to access files that are referenced in prog's include directives

func (*Converter) ConvertFile added in v0.0.10 

func (c *Converter) ConvertFile(mainfile string) (*ast.Program, error)

ConvertFile is a shortcut that loads a file from the file-system, parses it and directly convertes it. mainfile is the path to the file on the disk. All included are loaded relative to the mainfile.

func (*Converter) ConvertFileEx added in v0.0.10 

func (c *Converter) ConvertFileEx(mainfile string, files FileSystem) (*ast.Program, error)

ConvertFileEx acts like ConvertFile, but allows the passing of a custom filesystem from which the source files are retrieved. This way, files that are not stored on disk can be converted

func (*Converter) Debug added in v0.0.7 

func (c *Converter) Debug(b bool)

Debug enables/disables debug logging

func (*Converter) GetVariableTranslations added in v0.0.13 

func (c *Converter) GetVariableTranslations() map[string]string

GetVariableTranslations returns a table that can be used to find the original names of the variables whos names where shortened during conversion

type DiskFileSystem added in v0.0.10 

type DiskFileSystem struct {
	Dir string
}

DiskFileSystem retrieves files from a directory on the disk

func (DiskFileSystem) Get added in v0.0.10 

func (f DiskFileSystem) Get(name string) (string, error)

Get implements FileSystem

type FileSystem added in v0.0.10 

type FileSystem interface {
	Get(name string) (string, error)
}

FileSystem defines an interface to get the content of files by name used so the converter can query for the content of files mentioned in include-directives

type MemoryFileSystem added in v0.0.10 

type MemoryFileSystem map[string]string

MemoryFileSystem serves files from Memory

func (MemoryFileSystem) Get added in v0.0.10 

func (f MemoryFileSystem) Get(name string) (string, error)

Get implements FileSystem

type Parser 

type Parser struct {
	*parser.Parser
}

Parser parses a nolol-program

func NewParser 

func NewParser() *Parser

NewParser creates and returns a nolol parser

func (*Parser) Debug added in v0.0.7 

func (p *Parser) Debug(b bool)

Debug enables/disables debug logging

func (*Parser) Parse 

func (p *Parser) Parse(prog string) (*nast.Program, error)

Parse is the entry point for parsing

func (*Parser) ParseBlock added in v0.0.9 

func (p *Parser) ParseBlock(stop func() bool) *nast.Block

ParseBlock parse lines until stop() returns true

func (*Parser) ParseBreak added in v0.0.14 

func (p *Parser) ParseBreak() ast.Statement

ParseBreak parses the break keyword

func (*Parser) ParseContinue added in v0.0.14 

func (p *Parser) ParseContinue() ast.Statement

ParseContinue parses the continue keyword

func (*Parser) ParseDefinition added in v0.0.12 

func (p *Parser) ParseDefinition() *nast.Definition

ParseDefinition parses a constant declaration

func (*Parser) ParseElement added in v0.0.10 

func (p *Parser) ParseElement() nast.Element

ParseElement parses an element

func (*Parser) ParseFuncCall added in v0.0.6 

func (p *Parser) ParseFuncCall() *nast.FuncCall

ParseFuncCall parse a function call

func (*Parser) ParseGoto 

func (p *Parser) ParseGoto() ast.Statement

ParseGoto allows labeled-gotos and forbids line-based gotos

func (*Parser) ParseIf 

func (p *Parser) ParseIf() ast.Statement

ParseIf overrides and disables the old yolol-style inline ifs

func (*Parser) ParseInclude added in v0.0.10 

func (p *Parser) ParseInclude() *nast.IncludeDirective

ParseInclude parses an include directive

func (*Parser) ParseMacroDefinition added in v0.0.11 

func (p *Parser) ParseMacroDefinition() *nast.MacroDefinition

ParseMacroDefinition parses the definition of a macro

func (*Parser) ParseMacroInsertion added in v0.0.11 

func (p *Parser) ParseMacroInsertion() *nast.MacroInsetion

ParseMacroInsertion parses a macro insertion

func (*Parser) ParseMultilineIf 

func (p *Parser) ParseMultilineIf() nast.Element

ParseMultilineIf parses a nolol-style multiline if

func (*Parser) ParseNestableElement added in v0.0.11 

func (p *Parser) ParseNestableElement() nast.NestableElement

ParseNestableElement parses a NOLOL-Element which can appear inside a blocl

func (*Parser) ParseProgram 

func (p *Parser) ParseProgram() *nast.Program

ParseProgram parses the program

func (*Parser) ParseSingleExpression added in v0.0.14 

func (p *Parser) ParseSingleExpression() ast.Expression
