Note that this version interprets a `:` as specifying a format string (as per standard string formatting), so if slicing is required, you must explicitly create a slice. This is to be used in templating cases, such as the parallel batch script templates, where simple arithmetic on arguments is useful. Examples -------- :: In [1]: f = EvalFormatter() In [2]: f.format('{n//4}', n=8) Out[2]: '2' In [3]: f.format("{greeting[slice(2,4)]}", greeting="Hello") Out[3]: 'll' cCst||}||fSr)eval)r nameargskwargsvr r r get_fields zEvalFormatter.get_fieldN)rrr r!rr r r r rsrc@s eZdZdZeedddZdS)FullEvalFormatteraiA String Formatter that allows evaluation of simple expressions. Any time a format key is not found in the kwargs, it will be tried as an expression in the kwargs namespace. Note that this version allows slicing using [1:2], so you cannot specify a format string. Use :class:`EvalFormatter` to permit format strings. Examples -------- :: In [1]: f = FullEvalFormatter() In [2]: f.format('{n//4}', n=8) Out[2]: '2' In [3]: f.format('{list(range(5))[2:4]}') Out[3]: '[2, 3]' In [4]: f.format('{3*2}') Out[4]: '6' ) format_stringreturnc Csvg}||D]\\}}}}|r(|||dur|rBd||g}t||} || |} ||| dqd|S)N:r,)parserEr+r convert_field format_field) r rrrresult literal_text field_name format_spec conversionobjr r r vformat s   zFullEvalFormatter.vformatN)rrr r!r?rr r r r rsrc@s*eZdZdZedZddZddZdS)DollarFormatteraFormatter allowing Itpl style $foo replacement, for names and attribute access only.
