I just got a crash report (at launch), after submitting my app to the Mac App Store, for review :

This is the part of code, I'm suspecting :

Do you see anything "obviously" wrong with the above? (It's being called like 4-5 times, from awakeFromNib, so I guess that's the culprit...)
HINT : The retains have been added after the report; I don't know if it's going to help though at all...
[NSFont fontWithName:#"Garamond" size:15.0] probably returns nil. As far as I know it's not a default font on OSX. So your objects array is empty, because only the objects up until the first nil are added.
i think the problem is here - [NSFont fontWithName:#"Garamond" size:15.0]
This code returns nil, so the array is empty.
May be this font is not standard but it is installed on your computer.
if the problem is here, you should add this font to app resources.

I have written a function that takes an input string and wraps the input text to a specified width that is passed in as a parameter. Right now, it takes approximately 290ms to run this function 1,000 times with a 4000 character string.
Can anyone suggest ways to improve this function? I will be trying a number of ideas that I found online here, but I wanted to see if there are any recommendations here.

The function simply wraps text like this (with force =0):
1---------n
This is a
test
testing
123...
Then like this with force = 1:
1---------n
This is a
test testi
g 123...
So far the function performs pretty badly with a high number of sequntial calls:
I would like to get it to under 1 sec for atleast 500 thuosand calls idealy (although this may be wishful thinking).

In the end, I had a VERY impressive execution speed reduction from about 20min to 10 seconds for 1,000,000 calls to the function. That's a 99% improvement!
See here: https://community.oracle.com/thread/3700483
The main idea is:
SELECT rn, txt
FROM ( SELECT ROWNUM AS rn, TRIM (REGEXP_SUBSTR (:p_txt, '.{1,' || :v_linesize || '}( |$)', 1, ROWNUM)) AS txt
FROM DUAL
CONNECT BY ROWNUM <= CEIL (LENGTH (:p_txt) / :v_linesize) + 10)
WHERE txt IS NOT NULL
ORDER BY rn
The delimiter here is ' '.

Depending on your objectives it might be better to use a RSTDocument. Label are just that, labels. They don't adjust to content or text. Think of them as stickers. The (RSTDocment)[http://kivy.org/docs/api-kivy.uix.rst.html], still indicated as highly experimental though is more suitable for long texts, specially if they are dynamic. They actually includes the Scroll.

You can set the Label to be of the size of the texture inside it like this.
FloatLayout:
Label:
# adding a background to see the amount of space the label takes
canvas.before:
Color:
rgba: .5, .5, .5, .5
Rectangle:
size: self.size
pos: self.pos
text: "How can the only thing constant in the universe be `change` when\nchange itself is by it's very nature `not constant`?"
pos_hint: {'center_x': .5, 'center_y': .5}
size_hint: None, None
size: self.texture_size
However with this you would only get a label that just expands how much text is in it and would require you to add \n yourself to make it wrap. A better approach would be to let the text inside the label auto wrap at a certain width by setting text_size something like the following::
FloatLayout:
ScrollView:
# take half of parents size
size_hint: .5, .5
pos_hint: {'center_x': .5, 'center_y': .5}
Label:
canvas.before:
Color:
rgba: .5, .5, .5, .5
Rectangle:
size: self.size
pos: self.pos

Mirum est notare quam littera gothica, quam nunc putamus parum claram, anteposuerit litterarum formas humanitatis per seacula quarta decima et quinta decima. Eodem modo typi, qui nunc nobis videntur parum clari, fiant sollemnes in futurum.";
CGSize maxSize = {self.textView.contentSize.width, CGFLOAT_MAX};
CGSize computedSize = [self.textView.text sizeWithFont:self.textView.font
constrainedToSize:maxSize
lineBreakMode:UILineBreakModeWordWrap];
NSLog(#"Computed size - width:%f height:%f\nContent size - width:%f height:%f", computedSize.width, computedSize.height, self.textView.contentSize.width, self.textView.contentSize.height);
Console output:
Computed size - width:320.000000 height:450.000000
Content size - width:320.000000 height:484.000000
Why are not these values equal? At least heights.
What is the .bounds.size of the text view? If all text fits within the text view the content size can still be reported as the views full size.
The UITextView is implemented using an internal web view, with allot of private magic. It is generally not a good idea to trust the text view with anything apart from displaying and editing text. The internal measurements and calculations has, and will continues to, change between OS updates.
If what you want is to change the size of the UITextView to fit all text then you must let the text view itself do this calculation. For example:
CGRect frame = textView.frame;
frame.size.height = [textView sizeThatFits:CGSizeMake(frame.size.width, CGFLOAT_MAX)];
textView.frame = frame;
In html, you can do something like this
<p>
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent eget
aliquet odio. Fusce id quam eu augue sollicitudin imperdiet eu ac eros.
<em>Etiam nec nisi lorem</em>, ac venenatis ipsum. In sollicitudin,
lectus eget varius tincidunt, felis sapien porta eros, non
pellentesque dui quam vitae tellus.
</p>
It is nice, because the paragraph of text still looks like a paragraph in the markup. In haml, it looks like this
%p
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent eget
aliquet odio. Fusce id quam eu augue sollicitudin imperdiet eu ac eros.
%em Etiam nec nisi lorem
, ac venenatis ipsum. In sollicitudin,
lectus eget varius tincidunt, felis sapien porta eros, non
pellentesque dui quam vitae tellus.
Is there any way to totally inline a tag in haml?
Haml excels for structural markup, but it's not really intended for inline markup. Read: Haml Sucks for Content. Just put your inline tags as HTML:
.content
%p
Lorem ipsum <em>dolor</em> sit amet.
Or else use a filter:
.content
:markdown
Lorem ipsum *dolor* sit amet.
I know this is old. But figured I'd post this in case anyone lands here. You can also do this sort of thing in haml (And maybe more what the OP was looking for?).
%p Here is some text I want to #{content_tag(:em, "emphasize!")}, and here the word #{content_tag(:strong, "BOLD")} is in bold. and #{link_to("click here", "url")} for a link.
Useful for those situations where doing it on multiple lines adds spaces you don't want
I.E. When you have a link at the end of a sentence, and don't want that stupid space between the link and the period. (or like in the OP's example, there would be a space between the and the comma.
Just don't get carried away like i did in the example :)
You can inline HTML in any HAML doing
%p!= "Lorem ipsum <em>dolor</em> sit amet"
The != operator means that whatever the right side returns it will be outputted.
As a hybrid of these nice answers by others, I think you can define a Helper method in your application_helper.rb for some inline markups you'd frequently use. You don't need to mix HTML with HAML, nor do you have to type much.
In your helper;
def em(text)
content_tag(:em, text)
end
#def em(text)
# "<em>#{text}</em>".html_safe
#end
In your haml;
%p
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent eget
aliquet odio. Fusce id quam eu augue sollicitudin imperdiet eu ac eros.
#{em 'Etiam nec nisi lorem'}, ac venenatis ipsum. In sollicitudin,
lectus eget varius tincidunt, felis sapien porta eros, non
pellentesque dui quam vitae tellus.
It's all about indentation:
%p
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent eget aliquet odio. Fusce id quam eu augue sollicitudin imperdiet eu ac eros.
%em
Etiam nec nisi lorem, ac venenatis ipsum. In sollicitudin, lectus eget varius tincidunt, felis sapien porta eros, non pellentesque dui quam vitae tellus.
I'm taking some user data and adding it to a PowerPoint presentation using VSTO. To get the formatting to look right, though I need to be able to set the left margin of some of the text in the textbox. There will be an initial block of text followed by another, indented block. For example (underlines added to emphasize spacing):
Lorem ipsum dolor sit amet,
consectetur adipiscing elit. Sed
vestibulum elementum neque id rhoncus.
In fermentum eros nec dolor lobortis
sit amet fermentum est consequat.
Curabitur eleifend nunc eu odio
vehicula ut elementum erat aliquam. Ut
adipiscing ipsum sit amet leo pulvinar
hendrerit. Cum sociis natoque
penatibus et magnis dis parturient
montes, nascetur ridiculus mus. Nulla
non neque in velit lacinia tempor et a
lacus.
___________Cras auctor bibendum urna, a facilisis lacus
lacinia non.
___________Nullam at quam a mauris consequat vulputate sed eu
sapien.
___________Fusce sed urna nulla, ut sagittis lacus. Pellentesque
tortor
___________augue, scelerisque at aliquet a, pretium ac
ipsum.
I can get this effect by setting Shape.TextFrame.TextRange.IndentLevel = 2 on the lower block of text. However, I cannot figure out how to programmatically set the value of the margin. Does anyone know how to do this?
This is taken care of via Shape.TextFrame.MarginRight and Shape.TextFrame.MarginLeft and the like.
