def SagePromptTransformer():
r"""
Strip the sage:/....: prompts of Sage.
EXAMPLES::
sage: from sage.repl.interpreter import SagePromptTransformer
sage: spt = SagePromptTransformer()
sage: spt.push("sage: 2 + 2")
'2 + 2'
sage: spt.push('')
''
sage: spt.push("....: 2+2")
'2+2'
This should strip multiple prompts: see :trac:`16297`::
sage: spt.push("sage: sage: 2+2")
'2+2'
sage: spt.push(" sage: ....: 2+2")
'2+2'
The prompt contains a trailing space. Extra spaces between the
last prompt and the remainder should not be stripped::
sage: spt.push(" sage: ....: 2+2")
' 2+2'
We test that the input transformer is enabled on the Sage command
line::
sage: from sage.repl.interpreter import get_test_shell
sage: shell = get_test_shell()
sage: shell.run_cell('sage: a = 123') # single line
sage: shell.run_cell('sage: a = [\n... 123]') # old-style multi-line
sage: shell.run_cell('sage: a = [\n....: 123]') # new-style multi-line
We test that :trac:`16196` is resolved::
sage: shell.run_cell(' sage: 1+1')
2
sage: shell.quit()
