Hi folks,
I've been using ironpython2.7 in a project, and I was generating some
csharp code when i discovered that I couldn't use use str.format
because the interference with the brackets-aplenty situation in
csharp.
In [1]: code = "class {0}Model { public bool IsModel(){ return
true; } }"
In [2]: code.format('My')
---------------------------------------------------------------------------
KeyError Traceback (most recent call
last)
KeyError: ' public bool IsModel(){ return true; } '
Please note I had no trouble with the trusty old % interpolation
method.
Now given that using str.format in this use case (code generation) is
equally difficult for other bracketed languages, and that str.format
is supposed to eventually become 'best-practice' for python string
formatting, can I get some feedback on a proposal that for the odd
case when brackets don't cut it, there is a way to redefine the
delimiter for str.format so that one could do something like this:
str.format_delimiter = ("[[", "]]")
and we could write something like this:
In [1]: code = "class [[0]]Model { public bool IsModel(){ return
true; } }"
In [2]: code.format('My')
Out[3]: 'class MyModel { public bool IsModel(){ return true; } }'
Please give your +N or -N and reasons below.
AK
