I just started playing with Dart in Dart Editor.
Since Dart Editor is a distribution of Eclipse, I figured that to format my code, all I'd need to do is press crtl + shift + f. However, when I did this, it brought up the "find/replace" window instead. I tried seeing if there were any options in "preferences" to fix this, but I found none. (The preferences seem a bit bare-bones at this point.)
So, is there a short-cut key for formatting code? And if there is, why is it not crtl + shift + f like it is in other distributions of Eclipse?
Update:
With Dart 1.2, released 2/26, you can format code through the Source menu, although the source menu doesn't exist in some situations and I'm not sure why. You can also use the shortcut Ctrl + Shift + R by default. To modify what the short cut is, you can go to Tools --> Preferences --> Key Bindings --> Export to File. Then search in the file for "Format" and modify the correct key binding, then reimport it.
Old answer:
The autoformat function for Dart code in the Dart Editor has not been introduced yet. From what I've read in the Dart formatter issue on the Dart issue tracker, it sounds like it should be introduced in version 1.2 of the Dart Editor, which hopefully won't be too long from now.
I actually did see it and use it for a few days (I think they rolled back 1.2), but there was still no keyboard shortcut for it. It was an option you needed to manually click. (Hopefully you can bind it yourself to a shortcut.)

I have a question about Xcode (Swift). Sometimes when I write an if statement. Something like this:
if(a == 2){
//do Sth
} else {
//do Sth
}
Xcode throws me an error: "Invalid character in source file"
I know it is no big deal and fixed by clicking on "Fix-it" but I want
to know what is the problem. That doesn't make sense to me...
My Xcode is on 7.2 and I am using Swift - I don't know if this is just a Swift problem.
For me it's the ESC key - it's completely reproducible! If I go to search and hit ESC in the search window I also find the occurrences marked - and can replace those with nothing. But it's not shown even with "Show invisible"!
final solution: Bind ESC keybinding to "Cancel". It's that simple.
I was having this problem. The way I solved it is by 1) copying whatever you have into Sublime Text or another code editor and having a look (you may need to enable viewing hidden characters). Mine had a code in there DC2 which is some sort of ASCII control character. For me it was caused by the fact that I had put the playground into manual execute and bound a keyboard shortcut to it that seemed to be entering that control character every time I executed it using the shortcut. I just changed the shortcut and removed the ASCII characters as I was able to see them in Sublime Text. (The link in the comments to the OP concerning left to right mode made no sense and didn't work for me.)
I encountered this problem when I was using a non-Apple keyboard with my iMac. Probably your case too. They add unnecessary control characters! One way to fix it in Xcode ischoose from the menu Editor>Show Invisibles and see if there are any unwanted characters where the error is being thrown and remove them.
Editor->Show Invisibles did not show the character that was causing a problem for me. No-break-space (u00a0) will be shown as a space with no "dot" indicator. However, that's really hard to see and I completely missed it the first time. Zoom helps.
One way I found to detect invalid characters is to use Visual Studio Code and enable the settings:
"editor.renderControlCharacters": true
"editor.renderWhitespace": "all"
This has the same visibility issue with no-break-space as Xcode, however it does show other special characters.
To make it more obvious and possibly detect more invalid characters, install the extension "ascii-unicode-escape" and follow the instructions.
I don't understand why Xcode allows these invalid characters, inserts them into your source files for no reason, and doesn't even give an option to detect them! I'm trying to write code, not secrets in invisible ink, damnit!! I guess it's less of an issue for compiled code, which will show an error, but not so convenient with shader code.
I'm having the same issue. I found a solution after extensive testing. Hopefully it could save others extensive hours of researching into this terrible Xcode experience.
The problem is I have a FILCO Minila keyboard, which has the 'App' key right next to 'left arrow'. I would accidentally hit 'App' when typing really fast, and it enters a 'DEL'(Data Link Escape, Unicode 0010) invisible character. It could only be seen when copy-pasted to Sublime. It's not even visible under Xcode's own 'Editor -> Show Invisibles'(Talking about good user experience...)
Magically this doesn't happen to Sublime or VSCode, only to Xcode. So no excuses for Xcode I guess?
The fix is to download Karabiner, an advanced keymapper for macOS, and invalidate the 'App' key or map it to something else. Karabiner would also invalidate your keymapping in the system default keyboard config. So you would have to remap stuff like 'cmd', 'alt' if you've customized them. If so, be sure to map both left & right modifier keys in Karabiner, because according to Karabiner's key event viewer, the system default keymap would map left_alt & left_cmd to right_cmd and right_alt... Just annoying as hell...
It took me 2 months to realize this problem and 2 hours to actually find out it's the 'app' key that's the culprit and fix it.
I'm using XCode 10.1.
With Xcode: Xcode does not help even after showing invisibles.
Then you can copy the code to Sublime Text => you will see these invisible characters which are the <0x0f>. Click the image to see in details.
With Sublime Text 3, it works!
=> Then you know where to remove the redundancies. Hope that helps!
Are you using the option ⌥ key for any keyboard shortcuts? This was my issue. It seems combining the option key with other keys can insert hidden characters.
For me, this happened when I used the ⌃+⌥+p shortcut in Xcode to resume the SwiftUI preview canvas. It added a 0x10 character. I discovered this, as other posters have recommended, by pasting the code from Xcode into Sublime Text.
(NB: I should have been using ⌘+⌥+p).
Is it possible - only compile/make source in C++ Builder (XE7) without the long delay of linking?
If yes, is there a shortcut key for it?
It would be very useful when I just want to check if my code compiles at a point, but don't want to execute it.
mauroaraujo is right - since BCB4 or thereabouts the Project menu has an item that is misleadingly labelled 'Build ' + current source file. This compiles the current .cpp file (compiler switch -c). The item description in the documentation is a bit misleading as well.
The standard keyboard shortcut is Alt+F9 - the same as it always has been ever since the times of Turbo C/C++ (with the possible exception of some early C++Builder incarnations). The shortcut might change or disappear when certain editor key mappings are selected, though.
There seems to be no direct equivalent to 'Syntax check' item that becomes available in the Project menu when the current source is a .pas file, but for most practical purposes it should be close enough.
What the IDE doesn't seem to have is a command for compiling all sources without linking (sort of like a 'syntax check all sources'). However, you may be able to build a custom target where the link phase is configured to do nothing.
I am using Xcode 6.1 on Yosemite, writing IOS apps using swift.
For example:
If I type:
myClass.st
I was hoping the editor to show me this:
myClass.SetTitle()
but the reality is not what I had expected.
the editor says no match. In case of visual assist or Sublime Text, "st" mathes "SetTitle"
Sometimes people only remember a few keywords of the long variable name, rather than the full name from the very beginning.
Is is possible to solve this issue by some plugins?
Thank you
I think I have found the answer to this.
The plugin is called
FuzzyAutocompletePlugin

I'm using Sublime 2 for Ruby On Rails programming.
I need a ability to click a method name and jump to class where the method is defined. There are many IDE with similar capability...
Goto symbol is Ctrl-R (linux), this gives a pop-up-list of all symbol and class definitions in the file, in definition order, and you can jump to what you're after. You could do the same thing with Goto Anything, Ctrl-P and then typing # and the method name.
Also, there is a Goto Symbol plugin, which lets you jump straight to the definition of the method name your cursor is at, with a key binding or click.
However, both those methods are limited to the current file. If you need to jump to definitions in other files, probably the best solution is the SublimeCodeIntel plugin. It seems to be working pretty well and just by hitting Ctrl-f3 (linux) will open up the file at the definition you want.
Another solution is CTags.
SublimeCodeIntel seems to be pretty buggy judging from unresolved issues on the Github tracker. Also it crashes for me, probably because the code base I'm working on is too big...
What I'm using now is the CTags package. There's no "intelligence" but it allows you to jump to definitions and back very easily and it is super fast.
upgrade to sublime text 3 and then put cursor on function name and click F12
to go back ALT+-
or from the menu click on Goto
I keep writing codes in gedit but at the end of the week we need to submit a lyx literal programming file. Copying and pasting or importing is painful, since , we need to keep pressing tabs or enters. Can anyone suggest a simple alternative to this? Please keep in mind that we need to export the c file from the lyx file.
With the help of my friend, i have written a python code to convert the python or c or any other code, as it is to a lyx file. you can later add whatever you want to the lyx file
Here is the link: http://dpaste.com/hold/671718/
The aforementioned link is broken, but here's the original.
The script essentially takes code and creates LyX scrap from it. It requires that scrap and noweb be installed on the machine in question. Also, I believe I'd made this for LyX v.1.6. Not sure how it will hold up against newer versions. Then again, one can select and indent using tab in scrap code in the newer versions, so the OP's problem is somewhat mitigated.
