Control macro usage formatting in Rustfmt - rust

I want to write a simple call to assert! like this
assert!(idents.len() == 1, "Multi-part table references not supported");
But this keeps getting formatted to:
assert!(
idents.len() == 1,
"Multi-part table references not supported"
);
But I don't really like this particular formatting behavior; I'd like it to stay on one line. I tried setting the fn_call_width in my rustfmt.toml file to a higher number, but that didn't help. Note that my max_width is still the default value (100).
Does anybody know if there is a config I can set in the rustfmt.toml that can get me the desired behavior?

Ahh, I just realized that changing the width settings, like fn_call_width won't change anything if use_small_heuristics is set to "Default" (which it is by default). I have to either do use_small_heuristics = "Off", or I have to increase my max_width (which rustfmt uses to compute settings like fn_call_width when use_small_heuristics = "Default").

How to properly use .itemconfigure() in tkinter

I am trying to remove the underline from the items in my list box when i select it. I tried giving the entire list box the "activestyle=None" but i learned that you need to use the "itemconfigure". What i am lost on is what i should be putting for index. I have my .insert index as 'end' and it works properly but when i do that for the item configure it says its out of range. Here is the code if anyone can assist me here.
taskList = Listbox(setBox, bg="#1B2834",fg="white")
taskList.configure(width=183,height=39, activestyle=None, fg="#4299E9", selectbackground="#061523",
selectforeground="#4299E9")
taskList.itemconfigure('end', activestyle=None)
taskList.insert('end', taskIDnum)
You don't use itemconfigure to set the activestyle attribute. You should use the configure method of the listbox. The documented value to turn off the ring around active item (or underline, depending on platform) is the string "none", not the python value None.
taskList.configure(activestyle="none")

How to suppress warnings in vim-latex?

I want to hide a couple of problematic warnings in vim-latex, but I can't seem to work out the syntax.
I currently have:
let g:tex_IgnoredWarnings =
\'Underfull'."\n".
\'Overfull'."\n".
\'specifier changed to'."\n".
\'You have requested'."\n".
\'Missing number, treated as zero.'."\n".
\'There were undefined references'."\n".
\'Citation %.%# undefined'."\n".
\'Double space found.'."\n"
let g:Tex_IgnoreLevel = 8
To me, that looks correct per the documentation, but the "Double Space Found" warning still appears (to clarify, by 'still appears' I mean that it's highlighted on the left of the screen with S>).
Any ideas?
The property you're setting should start with an uppercase letter (g:Tex_IgnoredWarnings as opposed to g:tex_IgnoredWarnings. The way you have it now, vim-latex is using the default value for g:Tex_IgnoredWarnings and not your desired overrides.

Problems with jqPlot / Primefaces extender and Date values

so here's the thing.
I've got plenty of persisted "Snapshots" containing a java.sql.Timestamp and (for the sake of simplicity) an int as data.
I have a JSF page containing a primefaces 3.4.1 <p:lineChart> and behind that a ManagedBean that contains the model for the chart.
Let's say I then select a time range and fetch all the Snapshots in between that range.
and populate the data model for the chart with all the Timestamps (x-axis) and all the integers (y-axis).
So what i do while populating is:
data = new HashMap<Object, Number>();
List<Snapshot> allSnapshots = persistenceService.getAllSnapshots();
for(int i = 0; i < allSnapshots.size(); i++) {
Snapshot s = allSnapshots.get(i);
data.put(new Date(s.getTimestamp().getTime()), s.getData());
}
chartModel.getSeries().get(0).setData(data);
(Note: in the example code I just fetch all Snapshots, as I quickly just generated a hundred or so).
I set up the chart like this:
<p:lineChart id="chart" value="#{backingBean.chartModel}" xaxisAngle="-90">
<f:convertDateTime pattern="HH:mm:ss"/>
</p:lineChart>
It works ok but when the model contains a hundred data points, the xaxis is just overcrowded with all the tickmarks.
What I then did is to use the primefaces' option to use a jqplot extender function.
So I just add extender="extend" as attribute for the chart, where extend is the following js function :
function extend() {
this.cfg.axes = {
xaxis: {
renderer: $.jqplot.DateAxisRenderer,
rendererOptions: { tickRenderer: $.jqplot.CanvasAxisTickRenderer },
tickOptions: {
showGridline: true,
formatString: '%H:%M',
angle: -90
}
}
}
}
This is the current version of it..
After hours of reading and trial and error, I still cannot get it right, as the following things are just never right:
The tick marks never get rendered as the Date never gets converted.
At the moment this is just ignored and the formatString itself is
displayed...
Additional tick marks are created left and right of the actual data,
I dont want that.
When I only give autoscale: true as option for the jqplot extender,
I would expect just the spacing between the marks turn ok. But what
then happens is, that the spacing is cool but the original date
labels turn into just bare numbers starting from 0 to the amount of data available.. !?
I am getting a little tired from dealing with this.....maybe I am doing something fundamentally wrong. Otherwise I have no idea why this is so complicated..
Thanks for any advice!
Cheers
Chris
EDIT:
Ok thanks to perissf, I checked this one : https://stackoverflow.com/a/14287971/870122
With the suggested extender I get the following output :
http://www.abload.de/img/clipboard01y6sgj.png
(sorry I cannot post the image directly due to new user restrictions :-/ )
As you can see the tick marks are rendered correctly as HH:MM, thats very nice.
But as you also can see another quite weird problem occurs:
The given time range of the snapshots is
Start time: 2013-01-28 13:01:25.415
End time: 2013-01-28 13:14:32.145
I collected these as UTC timestamps with System.currentTimeMillis() while the JVM is set to UTC in the glassfish config.
As you notice, the datapoints in the plot are shifted one hour, they start at 14:01, which looks like the values have been auto-converted to my current timezone which is UTC+1. But the leftmost xaxis tick is placed at around the original UTC value at 13:00.
I collect the timestamps UTC as I dont know in which actual timezone the application will be running, but I'd like to display the "translated" time value. So the auto shift to my timezone is a nice feature, but the xaxis scaling is actually not nice and weird.
Any suggestions how I get rid of that ?
Cheers
Chris
EDIT2:
Ok while debugging the rendered page with Firebug I stumbled upon the jqplot internal variables in the plot object, which seem to contain the min and max values for the xaxis.
Min is set to the original min UTC value which is around 13:00, and max is set to the shifted UTC+1 value around 14:15.
Somehow the min value is not shifted accordingly to the automatic timezone adjustments.
All other values, that is dataBounds, data itself and so on, are all shifted nicely by one hour.
I opened a issue at Bitbucket jqplot issue tracker
Let's see.
Bye
Chris
i finally debugged the jqplot renderer and found some lines of code that cause this behaviour.
For anyone interested, please find the bugfix in the comment section here:
Bitbucket issue tracker
Thanks for any help
I'm very interested in this fix but the issues on BitBucket are in a restricted area so I cannot access it. So I had myself to try to fix this AxisDateRenderer and fortunately I did :)
So the Primefaces (6.0) chart uses an old version of the JQPlot library. A bug in this version sets the minimum date axis bound being not the first value exactly, but a time older according to the locale time zone of the user browser. For example, if the first value is at 12:00 and your GMT is GMT+1, then the date axis bound minimum will be at 11:00 instead of 12:00 !
The minVale
The following line (in createTicks function) should bed replaced (note the code is written minified below)
ad = ad.getTime() + ad.getUtcOffset();
By the next line:
ad = Math.floor((ad.getTime() - ad.getUtcOffset())/r) * r + ad.getUtcOffset();
Non minified line to replace:
min = min.getTime() + min.getUtcOffset();
With:
min = Math.floor((min.getTime() - min.getUtcOffset())/tempti) * tempti + min.getUtcOffset();
Note that I have tried to update the chart.js of Primefaces to an earlier version , but the chart do not work anymore. I will wait for the next update of Primefaces hoping that a newer version is used. I also don't know which version of JQPlot is used in Primefaces 6.0

Height of tab (JTabbedPane) does not change

As the title says, the height of my tabs is not increasing as it should, my code looks like this:
JTabbedPane jtp = new JTabbedPane();
JLabel iconInTab = new JLabel(new ImageIcon("myImage.png"));
iconInTab.setPreferredSize(new Dimension(100,80)); // is the size of my Image, I've also try to do this using getSize
jtp.addTab(null,new JPanel());
jtp.setTabComponentAt(0,iconInTab);
I've also try this using html but it did not work either:
jtp.addTab("<html><p><p><p></html>",new ImageIcon("myImage.png"),new JPanel());
with the first code the problem is not the change of the size horizontally (the width change correctly), the problem is only on the height, with the second code, if I add multiple lines inside the html code, the text appear incomplete (just show the middle line) (also the width behaves as expected, the problem is the height). . .
why is this happening? or how could I get this done?
Note: S.O.: Mac OS X 10.8.1
Solved!!! The problem was that the default UI over MAC OS X (com.apple.laf.AquaTabbedPaneContrastUI), you only need to change it to the basicTabbedPaneUI (or the one of your preference), in my particular case I need to extend this class (it was a pain in the *, because what I wanted was really complex) to get the look & feel that I was expecting, if you have the same trouble just do this before adding your tabs:
myTabbedPane.setUI(new BasicTabbedPaneUI());
Note: Checking the default UI of your TabbedPane, may solve many different problems.

Increasing the number of suggests shown in omnibox

Is it in anyway possible to increase the number of suggests that your extension may show in the omnibox?
By default it looks like 5 rows is the limit. I've read about a command line switch to change the number of rows (--omnibox-popup-count) but I am really interested in dynamically being able to set this in my extension.
5 rows isn't really enough for the information my extension want to show.
[Update 2018 - thanx version365 & Aaron!]
» Not hardcoded anymore! chrome://flags/#omnibox-ui-max-autocomplete-matches . Credit goes to #version365 answering below: http://stackoverflow.com/a/47806290/234309 « – Aaron Thoma
..[historical] detail: since the removal of --omnibox-popup-count flag (http://codereview.chromium.org/2013008) in May 2010 the number [was] hardcoded:
const size_t AutocompleteResult::kMaxMatches = 6;
a discussion two years later on the chromium-discuss mailing list about the 'Omnibox default configuration' "concluded"
"On lower performing machines generating more result would slow down the result display. The current number look like a good balance."
[which is not a very valid argument, considering the probably infinitesimal overhead retrieving more items than the hard-wired number]
why the heck is there no chromium fork that removes stupid UX limitations like this (or the no tabbar in fullscreen mode)^^
Since there is no more --omnibox-popup-count flag; you can use another flag which is new.
chrome://flags/#omnibox-ui-max-autocomplete-matches lets you select a maximum of 12 rows.
In fact there is no more --omnibox-popup-count flag
http://code.google.com/p/chromium/issues/detail?id=40083
So I think there is no way to enlarge the omnibox.
