Hi, I just installed iPython using apt-get install on trusty and --version gives me 1.2.1 -- when stable seems to be 2.3. pip install --upgrade ipython fails miserably
should I start again from scratch using the documented method
?
Matthias Bussonnier

On which distrib are you ?
@ckemmler you can pip-install --user to install only for your user not system whide

@jdfreder, @ellisonbg: the warning when you import widgets I think is too much
especially if we are splitting off widgets to a separate repo and project after IPython 3.0
The warning says, "WARNING: The widget API is still considered experimental and
may change by the next major release of IPython." I think it's a given that there can be backwards incompatible changes in major releases. Especially if the widget package is split off from IPython

I guess nobody (in Berkeley) wants to go out in the storm?
Thomas Kluyver
@takluyver
Dec 11 2014 17:26
so far, the "storm" just looks like ordinary rain from here. But the TV is busy saying that it's life threatening, and I should on no account venture outside, so...

Haha, I haven’t even been looking at the tv
Oh, huh
Min RK
@minrk
Dec 11 2014 17:27
But yeah, right now it looks like 'pretty wet'
maybe there was a lot of wind over night or something
Brian E. Granger
@ellisonbg
Dec 11 2014 17:28
Oh, given the news, I thought Berkeley had been consumed by apocolyptic rain, protests, etc and vanished altogether
Thomas Kluyver
@takluyver
Dec 11 2014 17:29
maybe the New World Order is controlling the weather to damp down protests
Min RK

in the UK, it's widely rumoured that unpopular legislation is pushed in the winter because people are less willing to protest.
Brian E. Granger

Although, I think the New World Order would figure out how to just make it rain on black people

it's raining pretty hard here, but no serious damage.
but I was worried that the commute back in the evening would be hell/impossible. LBL sent out a warning to all employees to stay home.

I have to drive through hills/woods quite a bit, and if lots of trees go down, that could turn into hours stuck.
Min, can you run the meeting?

I added @jasongrout 's comment to the agenda
Jason Grout
@jasongrout
Dec 11 2014 18:18
Considering that we would be splitting out widgets from base IPython after 3.0, they literally are disappearing before the next major release.
perhaps that's a reason to split them out before....
(it will be tough to backport fixes, etc., with the code being in two different repos)
so @jdfreder: you can change my agenda item to: splitting out widgets before 3.0. Unless you want to talk about it a bit before then. If needed, I can hop on using my phone...
Jonathan Frederic
@jdfreder
Dec 11 2014 18:27
Jason Grout
@jasongrout
Dec 11 2014 18:36
lots of systems use pkg-config to find various settings a package was installed by
(don't know if that is helpful in this prefix discussion, though)
the naming convention is like git, right?
git-mypackage is invoked when you do git mypackage, IIRC

Is there a way to validate the contents of a trait? I know there’s _traitname_changed, but that doesn’t apply to default values, correct?
Thomas Kluyver
@takluyver
Dec 11 2014 19:36
isn't there a validate() method?
oh, right, but you have to get the trait instance
I forget if there's a public API for that
@minrk might know
Min RK
@minrk
Dec 11 2014 19:37
I think creating a new traitlet is appropriate
it's fine to have special use traitelets defined in subpackages
I don't think it's possible to add a validate function to be called, though you can raise TraitError in on_trait_change
Scott Sanderson
@ssanderson
Dec 11 2014 19:38
it might be nice to have a Predicate trait or somesuch that takes a validation function to its constructor
Jessica B. Hamrick
@jhamrick
Dec 11 2014 19:38
Ok, cool, thanks
Min RK
@minrk
Dec 11 2014 19:39
That's what we do most places - in _[trait]_changed, check the value, and either assign a new value, or raise a TraitError
Jessica B. Hamrick
@jhamrick
Dec 11 2014 19:39
Yeah
Min RK
@minrk
Dec 11 2014 19:39
but it would be perfectly fine to do that in a new traitlet with a validate method as well
Jessica B. Hamrick
@jhamrick
Dec 11 2014 19:39
Does _[trait]_changed get called when the initial value is set?
Min RK
@minrk
Dec 11 2014 19:39
No, if you want true validation of any possible value, a new traitlet is the only option
Jessica B. Hamrick
@jhamrick
Dec 11 2014 19:40
Ok
Min RK
@minrk
Dec 11 2014 19:40

would_be_an_integer_if_language_understood_that ;-)
Kyle Kelley
@rgbkrk
Dec 11 2014 20:11
Since Integers don't really exist in JavaScript
yeah
I think @takluyver's is best

hahah
well integer is short for what he typed.
Kyle Kelley
@rgbkrk
Dec 11 2014 20:11
It seems like people use integer
Jonathan Frederic
@jdfreder
Dec 11 2014 20:12
And I've been using float otherwise
Kyle Kelley
@rgbkrk
Dec 11 2014 20:12
Alright, we should use integer but interpret as shortening would_be_an_integer_if_language_understood_that
Jonathan Frederic
@jdfreder
Dec 11 2014 20:12
yeah
Kyle Kelley
@rgbkrk
Dec 11 2014 20:12
Otherwise you're going to have write number and then in the comments piece write that it must be an integer
Jonathan Frederic
@jdfreder
Dec 11 2014 20:13
And I think you're right, object > dictionary (> dict, which is Python specific)
(I added the last piece myself)
Kyle Kelley
@rgbkrk
Dec 11 2014 20:14
yeah
I sometimes still say associate array on accident
Guess which language I started with that had that interface. ;)

And also, I think your syntax for object keys would work well. I haven't been using it myself, but it seems like a good way to avoid nestisitis.

@rgbkrk
Dec 11 2014 20:16
yeah

def nestisitis: disease where an excess of indents pushes the content to the right margin, at which point wrapping causes the text to be reduced to one word per line.

I felt bad telling you to uppercase some of the comment starts
For the sake of consistency
I'll just write a summary
Jonathan Frederic
@jdfreder
Dec 11 2014 20:18
I agree
Most of them were inconsistent to start
Kyle Kelley
@rgbkrk
Dec 11 2014 20:20
yeah, I'm not nitpicking on you just that its there and we can clean it up
:)
Cool, after you fix those little pieces I'll merge
Jonathan Frederic

Honestly I haven't looked at the grammar yet, but it makes sense to do so now. Especially since we will be building docs from this.

We might hold #7116 if it's going to conflict with #6700, which has been open for a long time, and is close to ready

was on the phone with fernando

although given the syntax of @rgbkrk and @jdfreder it looks like your question is "ha"

@ellisonbg the question macro is a little more powerful than that. It uses a regex to check if the text is followed by a ?, but since there wasn't a ? it failed to parse. @minrk 's question==None

@ellisonbg should display.Math make inline or display math? ($$ vs ) Brian E. Granger @ellisonbg Dec 11 2014 22:34 Hmm, what does it do now @minrk ? Min RK @minrk Dec 11 2014 22:34 display Brian E. Granger @ellisonbg Dec 11 2014 22:34 That was my first thought just now Min RK @minrk Dec 11 2014 22:34 okay Brian E. Granger @ellisonbg Dec 11 2014 22:34 Why is this coming up? But I don't have super strong feelings - Min RK @minrk Dec 11 2014 22:35 #7184 in latextools, there's latex_to_png Brian E. Granger @ellisonbg Dec 11 2014 22:35 Does this relate to how math is indented in the notebook Ahhh, got it Min RK @minrk Dec 11 2014 22:35 in the qtconsole, it's called by stripping  and then passing wrap=True which is certainly wrong, because it breaks cases like 'where a=5' Brian E. Granger @ellisonbg Dec 11 2014 22:36 Yes Min RK @minrk Dec 11 2014 22:37 but mpl mathtext doesn't support display math, only inline, so when I removed that, it started failing In that PR, I hardcode text.replace('$$', '$') in mpl_tex2png Brian E. Granger @ellisonbg Dec 11 2014 22:38 So the main question is how should the latextools stuff handle all of this - rather than how display.Math works Min RK @minrk Dec 11 2014 22:38 partly I was thinking earlier than inline might be preferable, but now I think display is better Brian E. Granger @ellisonbg Dec 11 2014 22:40 I think is my preference by a little bit Min RK @minrk Dec 11 2014 22:40 that PR should fix various things, including rendering latex in the qtconsole, which just doesn't work right now in a variety of ways One can always use Latex('$inline\$') to get inline math, so it's not of any great consequence what we do in Math.

Don't think so, should be okay.
