[matplotlib-devel] config with traits
I am trying to work out some way to make rcdefaults() work with the traited
config. Along the way, I discovered this in mplconfig:
class mathtext(TConfig):
cal = T.Trait("['cursive']", mplT.FontPropertiesHandler())
rm = T.Trait("['serif']", mplT.FontPropertiesHandler())
tt = T.Trait("['monospace']", mplT.FontPropertiesHandler())
it = T.Trait("['serif'], style='oblique'",
mplT.FontPropertiesHandler())
bf = T.Trait("['serif'], weight='bold'", mplT.FontPropertiesHandler())
sf = T.Trait("['sans-serif']", mplT.FontPropertiesHandler())
use_cm = T.true
fallback_to_cm = T.true
I dont think that will work. One of the highlights of the new config files is
that when a file says:
[mathtext]
rm = ['serif', 'sans-serif']
you actually get a list, not a string, to pass to
mplT.FontPropertiesHandler(). I discovered the code by trying to do this:
rcParams.update(rcParamsDefault)
Another thing about T.Trait to keep in mind:
T.Trait("['cursive']", mplT.FontPropertiesHandler())
"['cursive']" is the default value and is *not validated*. Nor is it
necessarily an allowed value. For example:
T.Trait('small', 'medium', 'large')
'small' is the default value, but any future attempt to set that trait
to 'small' will fail. Only items following the default are allowed.
T.Trait('small', 'small', 'medium', 'large')
Now 'small' is a valid setting.

Re: [matplotlib-devel] config with traits
This was an attempt to do a direct translation from what I had in the
"classic" rcsetup.py. (The previous version in mplconfig.py was
semantically incorrect.) I had tested this with settings in my
matplotlib.conf, but didn't realise that the default wasn't validated
(and thus not interpreted into a FontPropertiesProxy object).

Right. But it works like:
rm = "['serif', 'sans-serif']"
I realize it's hacky. The most obvious alternative is to expect a
dictionary here, e.g.:
rm = { 'family': ['serif'], 'style': 'oblique' }
But that's less like the FontProperties constructor. My goal was to
make specifying fonts as similar as possible to the FontProperties
object so the user doesn't have to learn a new syntax. Is there a
better way to do this with Traits? Can the user specify the arguments
(with keyword arguments) to a constructor?

Mike

Re: [matplotlib-devel] config with traits
I've committed a fix so this at least works. (We can change how the
trait is specified later if necessary.) The validation is not as tight
as it should be, yet.
I think I've passed through this bug onto another one, though:
Traceback (most recent call last):
File "", line 1, in
File
"/home/mdroe/usr/lib/python2.5/site-packages/matplotlib/config/mplconfig.py",
line 469, in update
self[key] = arg[key]
File
"/home/mdroe/usr/lib/python2.5/site-packages/matplotlib/config/mplconfig.py",
line 454, in __setitem__
See rcParams.keys() for a list of valid parameters.'%key)
KeyError: 'text.fontangle is not a valid rc parameter.See
rcParams.keys() for a list of valid parameters.'
It seems that unlike the regular string choice traits, the custom Trait
handlers *are* called with the default value when initialized. Is that
something to be relied on? (Other parts of mplconfig, such as the
colors, depend on this).
Cheers,
Mike

Why do you say that? Here is the constructor:
def __init__(self,
family = None,
style = None,
variant= None,
weight = None,
stretch= None,
size = None,
fname = None,
):
wouldnt FontProperties(**rm) work?

I think this is getting a little out of hand, isnt it?:
#mathtext.cal : ['cursive']
#mathtext.rm : ['serif']
#mathtext.tt : ['monospace']
#mathtext.it : ['serif'], style='oblique'
#mathtext.bf : ['serif'], weight='bold'
#mathtext.sf : ['sans-serif']
That means we have comma-separated strings for lists of fonts, but
bracket-enclosed comma-separated quoted strings for mathtext properties.
If you want all that flexibility, why not do it in the usual way:
#mathtext.it.family : 'serif'
#mathtext.it.style : 'oblique'
But is that much flexibility needed?

Sure. I just meant that
rm = { 'family': ['serif'], 'style': 'oblique' }
is syntactically different from
rm = FontProperties(['serif'], style='oblique')

Well, they are different beasts. The former only specifies a choice of
families. The latter specifies a specific font. I didn't intend to
invent something new for mathtext -- there were no other instances where
a full set of font properties was required to specify a font. (Sure
font.* is a sort of example of that, but it includes other things as
well...)
> If you want all that flexibility, why not do it in the usual way:
>

> #mathtext.it.style : 'oblique'
That seems reasonable. I think I had a mental block around this because
of the verbosity (and seeing a font specification as a single unit), but
it does seem to fit in much better with the existing options (i.e. a
subset of font.*).
*IF* fontconfig is ever adopted, we could use fontconfig patterns as an
alternative, which are at least some kind of standard.
> But is that much flexibility needed?
The flexibility is certainly needed, and came directly out of a request
on matplotlib-user. There are cases where you want the variable names
(the 'it' font in TeX parlance) to be in an upright serif font. So you
can't hardcode either the family or the style. And there is no way
(AFAIK) to go from a given serif font to its companion sans-serif font,
so when changing to a new font "collection", each one will have to be
specified individually.

Mike
