Wikipedia: Regular expression
The text module exposes Go's regexp package through re_match, re_find, re_replace, and re_split. Patterns follow Go regexp syntax.
fmt := import("fmt")
text := import("text")fmt.println(text.re_match(`^\d{3}-\d{4}$`, "555-1234"))
fmt.println(text.re_match(`^\d{3}-\d{4}$`, "hello"))fmt.println(text.re_replace(`\d+`, "score: 42 and 7", "NUM"))parts := text.re_split(`\s+`, "one two three", -1)
fmt.println(parts)hits := text.re_find(`[a-z]+`, "a1b2c3", -1)
for _, m in hits {
fmt.println(m[0]["text"])
}re := text.re_compile(`(\w+)@(\w+)\.(\w+)`)
fmt.println(re.match("user@example.com"))try it
