Symbols - craterdog/go-component-framework GitHub Wiki
Overview
A symbol element represents the name of a variable rather than its value. Each symbol has the following string format:
$symbol: '$' identifier*
$identifier: LETTER (LETTER | DIGIT | '-')*
The source of this format is Bali Document Notation™ (Bali) defined here.
A Quick Example
To whet your appetite, here is some short example code that demonstrates the use of symbol strings.
package main
import (
fmt "fmt"
fra "github.com/craterdog/go-component-framework/v7"
)
func main() {
// Create a new symbol string using the module level constructor shortcut.
var symbol = fra.SymbolFromString(`$file-name`)
fmt.Println(symbol.AsString())
fmt.Println()
// Iterate through the characters that make up the symbol.
var iterator = symbol.GetIterator()
for iterator.HasNext() {
var character = iterator.GetNext()
fmt.Println(character)
}
}
