Variables ¶
var ( // Workbookfill wraps the xlsx object to provide a more wholistic worbook experience Workbookfill = `` /* 1308-byte string literal not displayed */ // Polyfill addes missing functionality implemented in JavaScript rather than Go Polyfill = `` /* 8415-byte string literal not displayed */ )
Functions ¶
func ToStruct ¶
ToStruct will attempt populate a struct passed in as a parameter.
ToStruct returns an error if it runs into a problem.
Example: a := struct{One int, Two string}{} val, _ := vm.Run(`(function (){ return {One: 1, Two: "two"}}())`) _ := ToSruct(val, &a) fmt.Printf("One: %d, Two: %s\n", a.One, a.Two)
Types ¶
type HelpMsg ¶
type HelpMsg struct { XMLName xml.Name `xml:"HelpMsg" json:"-"` Object string `xml:"object" json:"object"` Function string `xml:"function" json:"function"` Params []string `xml:"parameters" json:"parameters"` Msg string `xml:"docstring" json:"docstring"` }
HelpMsg supports storing interactive help content
type JavaScriptVM ¶
type JavaScriptVM struct { VM *otto.Otto AutoCompleter *readline.PrefixCompleter AutoCompleteTerms []string `xml:"autocomplete_terms" json:"autocomplete_terms"` Help map[string][]*HelpMsg `xml:"help" json:"help"` }
JavaScriptVM is a wrapper for *otto.Otto to make it easy to add features without forking Otto.
func New ¶
func New(vm *otto.Otto) *JavaScriptVM
New create a new JavaScriptVM structure extending the functionality of *otto.Otto
func (*JavaScriptVM) AddAutoComplete ¶
func (js *JavaScriptVM) AddAutoComplete()
AddAutoComplete populates the auto completion based on the help data structure
func (*JavaScriptVM) AddExtensions ¶
func (js *JavaScriptVM) AddExtensions() *otto.Otto
AddExtensions takes an exisitng *otto.Otto (JavaScript VM) and adds os and http objects wrapping some Go native packages
func (*JavaScriptVM) AddHelp ¶
func (js *JavaScriptVM) AddHelp()
AddHelp adds the interactive help based on the extensions defined in ostdlib
func (*JavaScriptVM) Eval ¶
func (js *JavaScriptVM) Eval(script string) (otto.Value, error)
Eval evaluate some JavaScript source code
func (*JavaScriptVM) GetHelp ¶
func (js *JavaScriptVM) GetHelp(objectName, functionName string)
GetHelp retrieves help text by object and function names
func (*JavaScriptVM) PrintDefaultWelcome ¶
func (js *JavaScriptVM) PrintDefaultWelcome()
PrintDefaultWelcome display default weclome message based on JavaScriptVM.HelpMsg
func (*JavaScriptVM) Repl ¶
func (js *JavaScriptVM) Repl()
Repl provides interactive JavaScript shell supporting autocomplete and command history
func (*JavaScriptVM) Run ¶
func (js *JavaScriptVM) Run(fname string) error
Run executes a specific JavaScirpt file
func (*JavaScriptVM) Runner ¶
func (js *JavaScriptVM) Runner(filenames []string)
Runner given a list of JavaScript filenames run the files
