Multiple lines of text in UILabel

Is there a way to have multiple lines of text in UILabel like in the UITextView or should I use the second one instead?

android ellipsize multiline textview

I need to ellipsize a multi-line textview. My component is large enough to display at least 4 lines with the ellipse, but only 2 lines are displayed. I tried to change the minimum and maximum number of rows of the component but it changes nothing.

Multiline strings in JSON

I'm writing some data files in JSON format and would like to have some really long string values split over multiple lines. Using python's JSON module I get a whole lot of errors, whether I use '\' or '\n' as an escape. Is it possible to have multi-line strings in JSON? It's mostly for visual comfort so I suppose I can just turn word wrap on in my editor, but I'm just kinda curious...

How do I match any character across multiple lines in a regular expression?

For example, this regex

(.*)<FooBar>

will match:

abcde<FooBar>

But how do I get it to match across multiple lines?

abcde
fghij<FooBar>

Best way to split string into lines

How do you split multi-line string into lines?

I know this way

var result = input.Split("\n\r".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

looks a bit ugly and loses empty lines. Is there a better solution?

Split code over multiple lines in an R script

I want to split a line in an R script over multiple lines (because it is too long). How do I do that?

Specifically, I have a line such as

setwd('~/a/very/long/path/here/that/goes/beyond/80/characters/and/then/some/more')

Is it possible to split the long path over multiple lines? I tried

setwd('~/a/very/long/path/here/that/goes/beyond/80/characters/and/
then/some/more')

with return key at the end of the first line; but that does not work.

Thanks.

How to center a two-line text in a TextView on Android?

I want to let it looks like this:

|    two    |
|   lines   |

Here is the current layout, not working at all.

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_vertical">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="two\nlines"
        android:layout_gravity="center_vertical"
        android:layout_centerInParent="true"/>
</RelativeLayout>

Any idea? Thanks!

Java multiline string

Coming from Perl, I sure am missing the "here-document" means of creating a multi-line string in source code:

$string = <<"EOF"  # create a three line string
text
text
text
EOF

In Java I have to have cumbersome quotes and plus signs on every line as I concatenate my multiline string from scratch.

What are some better alternatives? Define my string in a properties file?

Edit: Two answers say StringBuilder.append() is preferable to the plus notation. Could anyone elaborate as to why they think so? It doesn't look more preferable to me at all. I'm looking for away around the fact that multiline strings are not a first-class language construct, which means I definitely don't want to replace a first-class language construct (string concatenation with plus) with method calls.

Edit: To clarify my question further, I'm not concerned about performance at all. I'm concerned about maintainability and design issues.

Why doesn't Python have multiline comments?

OK, I'm aware that triple-quotes strings can serve as multiline comments. For example,

"""Hello, I am a 
   multiline comment"""

and

'''Hello, I am a 
   multiline comment'''

But technically speaking these are strings, correct?

I've googled and read the Python style guide, but I was unable to find a technical answer to why there is no formal implementation of multiline, /* */ type of comments. I have no problem using triple quotes, but I am a little curious as to what led to this design decision.

Android: Vertical alignment for multi line EditText (Text area)

I want to have 5 lines for the height of the text area. I am using the following code.

<EditText
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:singleLine="false"
    android:lines="5"
    android:layout_marginLeft="10dip"
    android:layout_marginRight="10dip" />

The text area looks fine, but the problem is that the cursor is blinking in the middle of the text field. I want it to blink at first line, at the first character of the text field.

Paste a multi-line Java String in Eclipse

Unfortunately, Java has no syntax for multi-line string literals. No problem if the IDE makes it easy to work with constructs like

  String x = "CREATE TABLE TEST ( \n"
             + "A INTEGER NOT NULL PRIMARY KEY, \n"
            ...

What is the fastest way to paste a multi-line String from the clipboard into Java source using Eclipse (in a way that it automagically creates code like the above).

Multiline for WPF TextBox

I am developing an app for sending some feedback.

Basically I'm trying to make a TextBox for comments, but I'm used to the WinForms MultiLine=true. I've set MinLines to 3, which is getting there, but preferably I'd like it if the user is able to type wherever in this block - like press enter and do dot points sort of thing. For example:

- Item 1        blah
- Item 2                blahlb lahbvl   d

But at the moment the text all stays on one line.

- Item 1         blah - Item 2                      blahb blahb blah

These comments will then help fill the body of an email which is sent. It may be pointless if I can't easily keep the same formatting when putting this string into the email body string (so that it looks like it does when sent as it does when typed).

Can I achieve what I'm after or do I have to leave it as all text on one line?

C multi-line macro: do/while(0) vs scope block [duplicate]

Possible Duplicates:
What’s the use of do while(0) when we define a macro?
Why are there sometimes meaningless do/while and if/else statements in C/C++ macros?
do { … } while (0) what is it good for?

I've seen some multi-line C macros that are wrapped inside a do/while(0) loop like:

#define FOO \
  do { \
    do_stuff_here \
    do_more_stuff \
  } while (0)

What are the benefits (if any) of writing the code that way as opposed to using a basic block:

#define FOO \
  { \
    do_stuff_here \
    do_more_stuff \
  }
