I want my first line at the top of the console to look like this:
, but mine looks like this, and it's long:
How can I shorten it to like the first picture?
I'm watching Java tutorials on youtube and their first lines ("C:\programs Files\Java\jdk\whatever"...) are always so short and pretty with 3 cute dots in the end, but mine is long and annoying.
You can define the lines which should be folded:
Right click on that line in the console
Choose "Fold Lines Like This"
Click OK
You can also define special keywords/phrases in this menu, where lines, which contains the phrase will be folded with ellipsis (...) at the end.
See the ConsoleViewImpl.java file in the source code of IntelliJ IDEA
This line (execution command) will be automatically hidden in case the string length is more than 1000 symbols.
So, once you add something to the execution command (for example by adding libraries), the execution command is folded automatically.

Hello I want to know any trick or shortcut by which one can know which is the longest file in project.
i.e which file has the longest lines of code.Is there any shortcut or plugin available?
I believe the OP was asking about the length of file, not the length of single line. You can try with such iteration:
(.*\n){100,}
(.*\n){1000,}
(.*\n){10000,}
Although this is kind of hacky it still works.
You can search your whole project using the regex repetition pattern. Just right-click your project folder in the project structure view and choose "Find in path...". Be sure to check "Regex" in the search window that appears.
So you'll start out and match any line with any length in your project
^.$
(If you're not familiar with regex: ^ and $ are used to denote the beginning and end of a line and . matches any character)
Then you gradually increase the number of matched repetitions
^.{1,}$
^.{10,}$
^.{100,}$
^.{1000,}$
(You use {start, end} to indicate to interval of repetitions. If you leave end blank it will match anything from start)
Using this you will soon be left with the longest line(s) in your project.
As I said it's kinda hacky but it's also quick and works if you don't have to automate the task.
Hope this helps you!
I have two java source files. Both represent the same class (semantically), but they were formatted differently.
For example, one of them contains the following line:
return Boolean.valueOf(Boolean.getBoolean("abc"));
While in the second file it looks like 2 lines:
return Boolean.valueOf(
Boolean.getBoolean("abc"));
In both cases, when I apply formatting (Ctrl+Alt+L), these lines do not change.
Is it possible to format them in some canonical way: that is, to get the same code if the only difference is formatting?
Equivalently: is there any way to remove all ignorable whitespace? Such a 'dried-out' program would then be easily restored using 'Reformat code'.
You should be able to do this if you turn off "Wrapping and Braces | Keep when reformatting | Line Breaks" in the Java code style settings.
Go to File > Settings > Ediotor > Code Style > java
in tab Wrapping and Braces uncheck line breaks
Apply and make (Ctrl+Alt+L) again.
I have a long method, after I type it in, it looks like this:
[someObj action1:param1 action2:param2 action3:param3 action4:param4];
But I want it to become like this... :
[someObj action1:param1
action2:param2
action3:param3
action4:param4];
...automatically after I type in the last semicolon.
I just saw a video that did this, so how do I do that?
(It is a paid video so can't give link here)
For the question text:
[someObj action1:param1 action2:param2 action3:param3 action4:param4];
if you have already entered that on one line just select the space between parameters and return
That will tend to alligh the colon ":" characters on multiple lines.
To auto-indent already entered code select the text that you would like auto-indented and then control i and that selection will be indented to Xcode rules.
I use that all the time.
If you just want to move a selected block of code to the left command [, to the right command ]
Have a look at https://github.com/travisjeffery/ClangFormat-Xcode.
It will reformat your code to adhere to style rules, like Chromium's for example, where the line length is 80 chars max.
In this case, the method will be wrapped as you mentioned if it's more than 80 chars.
You can either reformat on a particular key combination, or on each save.
I am working with another human being on project from that the professor expects to have uniform code-style. We have written large separate junks of code on our own, in which one has written single line comments without a white-space between the single-line-comment-token and the other one has inserted a white-space. We are working with IntelliJ and have failed to find an option to enable the Reformat Code function, to insert a white-space.
TLDR:
Can you tell us how to convert comments from that to this in IntelliJ?
// This is a load bearing comment - don't dare to remove it
//This is a load bearing comment - don't dare to remove it!
You can do a global search and replace (ctrl-shift-r on windows with default keyboard layout, or Replace in Path under the Edit/Find menu).
Check the regular expression option and enter //(\S.*) as the text to find and // $1 as the replacement. Check the whole project option, and clear any file masks. You can single step through the replacements, or simply hit the All Files option.
Is it possible without any code modification? Making a tab would insert 4 spaces, but in editor it would look like 2. I think it might be useful to display code from different libraries with the same indent size.
No. How could 4 spaces could look like 2? Only a Tab can look like any number of spaces.
