...A toy parser:
import gparser as gp # (1) import gparser
dot = gp.char('.') # (2) define a dot parser
result, restTxt = dot.run('./') # (3) run the parser
print(result) # (4) print the result
# Success(value=Result('.'))
print(result.get())
# .
print(restTxt)
# (1,2)
# ./
# ^Use run_strict to parse the entire input:
...
result, restTxt = dot.run_strict('.foo')
print(result)
# ParseError(msg='Excepted: <EOF>')
print(restTxt)
# (1,2)
# .foo
