String library

The FortiADC OS supports only the Lua string library. All other libraries are disabled. The string library includes the following string-manipulation functions:

• String.byte(s, i)

• String.char(i1,i2…)

• String.dump(function)

• String.find(s, pattern)

• String.format

• String.gmatch

• String.gsub

• String.len

• String.lower

• String.match

• String.rep

• String.reverse

• String.sub

• String.upper
