It'd be really handy to have collection KVC accessor snippets in xcode, as they're a pain to do by hand. Has anyone who's been using 4 for a while worked out how to add new ones?
(...we're allowed to talk about it now, right?)
Yes, it's quite easy - you just highlight text you want to use as a snippet and drag it into the snippets area (dragging selected text can be difficult, I find it works better if you drag from the left edge of the editor). It brings up a dialog box asking you to name it.
Also, you can have custom parameters in snippets - if you put the text <#paramName#> anywhere in the code you are dragging, when you use the snippet it will come up as a replaceable parameter that you can tab between just like in the official Snippets.
Also make sure to set a completion prefix, which makes it shorter to activate the snippet as you are typing. The nice thing about using Snippets over other solutions like global system text expanders, is that snippets can also be limited to being valid in a certain area of code - so for example a snippet that filled out a string formatting line can be marked as valid only within a block, not outside a method. That way the completion prefix only hits in areas where it's valid to use.
You can edit a snippet by clicking once on it, a box will come up with the snippet text and some other snippet settings you can edit.
A tip to help you drag the code every time, select text then click + hold (do not move mouse) until mouse pointer changes from "I" to pointer. You'll then be able to drag the selected text to the Code Snippet Library.
Drag the highlighted code to the Snippet library. (It can be stubborn and not want to drag. Holding the mouse button down for a moment before dragging seems to help.)
You can use Snippets to manage code snippets in Xcode. Check out this demo http://www.youtube.com/watch?v=il4kE4diy0k
Simply select the code, the press ALT key and drag it into the code snippets library and rename it there, Make sure to press the ALT key, other than this you won'n be able to drag it.

Could anyone point me in the right direction here? I am adding a custom toolbar and I want buttons for lots of different code snippets. We use so many that it is impracticable to remember all the different shortcut commands for each one, and selecting from a menu takes longer than just clicking a button.
It doesn't really even need to be specifically for a code snippet as defined by Visual studio, just simply pasting some text to the editor window, however I was hoping to be able to have some that would work as surround snippets, which the normal code snippets do.
You should call this:
(DTE2)base.GetService(typeof(DTE))
in the Initialize() method of the Package and save the resulting dte-instance in a field. When your button is clicked, you can use ((TextDocument)_DTE.ActiveDocument).Selection.Text) to retrieve the currently selected text, modify it and write it back as new selected text. Maybe you will have to cast the return value of the Selection-Property to TextSelection.
I have been developing in zend studio and there is a feature I miss a lot in Xcode. When you are reading code in a main function and you want to go in a specific function to read something, you can click in the left area of your current line of code were your are, and a flag-mark appears in that line of code, so you can go anywere else in the code and it will be very easy to come back to that line of code you were before because there is a flag and you only have to click on it and you automatically go back. Does Anybody know a similar way to do this in Xcode?
Unfortunately, this feature was present in earlier versions of Xcode (up to Xcode3 IIRC) and was called "Bookmarks", but it was removed since then.
You can use breakpoints (and disable them) as a workaround, even if it's not perfect. I personally prefer using other tricks, like "Open Quickly" and named tabs.
Alternate trick 1 : "Open Quickly"
One trick is to use Command+Shift+O (or "File" menu > "Open Quickly") to quickly open a file. In the field that appears, you can type:
The name or parts of the name of a file.
Typing "MainViewController" will propose to jump to the MainViewController.h or MainViewController.m file.
Typing "MainVC" will work too, as well as "MainViewCtrl", as long as the order of the letters you type is the same as the full name.
Very handy to just type "ContTVCell" to open the ContactsTableViewCell.h file that is hidden deep in subgroups of my project for example
Similarly, you may also type the name or parts of the name of a symbol, especially a method name.
For example, typing tvcellforrow will list you all the definitions of -tableView:cellForRowAtIndexPath: it could find in your project and let to jump to the one you want
When typing (parts of) the name of a file, adding : followed by a number at the end will allow you to directly jump at the corresponding line
For example, typing mvc:50 will propose you to jump to line 50 of MainViewController.h or MainViewController.m
Another trick : using (named) tabs
Don't forget that you can open tabs in Xcode, which can be very handy in this kind of situation.
When you are editing a file at some interesting position, you can create a new tab to browse elsewhere and go at any other place… and then go back to your first tab to find the code where you left it at the time you switched to the other tab.
Don't forget that you can name your tabs (simply double-click on their title) to give them a more explicit title. You may then quite think of them as "named bookmarks" somehow
Likewise, don't forget that you can detach tabs in separate windows too, if you prefer (for example to keep them around and visible on your secondary screen while you edit another part of your code)
You can even combine this with the "Open Quickly" trick presented above: once you made the "Open Quickly" field appear and typed something into it, instead of just validating using the enter key:
use Alt+Shift+enter to let Xcode present you a small widget that let you choose where you want the file to open (in the current tab, in another tab, in the assistant editor, in a dedicated window…)
use Alt+enter to open the file using the alternate navigation defined in Xcode preferences (Xcode > Preferences > Navigation > Optional Navigation). By default, the behavior when opening a file while using the Alt key is to open the file in the Assistant Editor. Personally I changed that in my Xcode preferences as I prefer to make Xcode open the file in a separate tab instead, which makes Alt+clic much more useful.
Sure, all those tricks with "Open Quickly…" and "Tabs" do not replace the bookmarks feature that you are missing. But they are still nice alternate ways to jump quickly to any position in your code, even any specific line of any specific file in your project, wherever you are in Xcode (even without having to have the Project Navigator visible on the left part of your window), and let you have multiple editors in different tabs to go quickly back to a part of interest in your code
its on top of your editor i have added two pics just check them.
When you navigate to another place in Xcode, say, open a different file, or Command-click and jump to definition, you can go forward and back by swiping right or left on the trackpad with two fingers.
You can also use keyboard shortcuts: Ctrl+⌘+→ to go forward, or Ctrl+⌘+← to go back.
Finally, you can click triangular buttons at the top left in your edit area.
There is a go back button at the top left of the editor!
If that is not good enough, whar I do is misuse breakpoints to set flags in my code. The breakpoint navigator thus becomes a table of flags. It isn't much but there you are.
Is it possible to change the width of the text editor in VS2012 - I've got a fairly wide screen and use fairly small text so I end up with a lot wasted real-estate in the middle of my screen.
I don't want to turn off word wrap - I just want the wrap to start further right on the line. If that makes sense!?
You can set this with HTML in Visual Studio 2012 but there is no global setting and it's missing in quite a few languages.
You can just put another "dummy" window next to the one you are writing in, so the actual editor window will be smaller. You can put it on the left if you want to pan the text to the right, and to the right if you want to shorten the lines.
I actually found the answer elsewhere; VS doesn't appear to provide this functionality but Resharper does. Resharper -> Options -> Code Editing -> C# -> Formatting Style -> Line Breaks and Wrapping -> Right margin (columns)
I put mine to 200 which fixed the issue
I know that this is not what you are looking for, but I believe it solves the same problem. I too have a fairly large screen and try to make use of it as optimally as possible.
I hate tabbing between code or design tabs and try to avoid that as much as possible.
VS has a feature that permits the user to create Horizontal or Vertical Tab groups and ever since I have started using it, I have found it very helpful. These options are present in the context menu by right clicking the tab or in the VS Window Menu (Menus are seen only if the tab groups feature is not active).
I have created a screenshot with Vertical Tab Groups created as shown below. In this example, I have a overview of both the designer and the code view at the same time.
We can use tab groups whenever there is a dependency such as comparing code, redesigning a module, etc. I know it takes a little time to get used to this feature but try it out and see :)
Can anyone tell me if there's a quick way to format your code in Text Mate, similar to pressing ctrl K+D in Visual studio?
Thanks!
Edit by Damien_The_Unbeliever:
For those not familiar with Ctrl K+D, it doesn't just indent code - it reformats it using the generally established formatting conventions in the editor - it may replace spaces with tabs or vice-versa for the indentation, ensure code is consistently indented, move braces to separate lines, etc.
TextMate reindenting and reformatting varies a little depending on the language you're using.
You can generally use the Text menu, that depending wether you have an active selection or not it will show you different commands under it. For example, if you have selected a section of code, there will be a Indent Selection menu item. If you have no active selection, it will be Indent Line.
To have this working properly, be sure to select the current language, if it isn't assigned yet (like on unsaved documents). If you're working with HTML, it will simply indent the lines depending on what's above it. It will keep line breaks intact.
If you need something to break out tags on new lines and properly format the document, you should use the Tidy command that is found in the Bundles menu, under HTML (or simply by using the shortcut CTRL+SHIFT+H. If you have a selection active at the moment that you use it, it will simply reindent that section. If instead you have no selection, it will properly reformat the whole document, including checking for tag validity and other errors.
The Bundles for other language have similar commands, like XML (still Tidy) and Javascript (that has a Reformat Document command).
As an ending note, I simply suggest to look into the Bundles menu; there are many little gems in it. ;)
Did you look in the menu bar? Under Text you have a couple of Reformat… entries that may fit your needs.
Beside these native features, some bundles — like the JavaScript one — have custom Reformat… commands : click on the little cog button at the bottom and explore your current language's bundle's content.
Recently switched to Textmate on Mac for coding. On PC when ever I want to tab in or out a block of code I just highlight and press tab or shift+tab to move it in our out. It's very useful when you are adding an extra loop or conditional statement to a block of code to keep everything tidy and neatly indented.
On Textmate however when I try this it just replaces my selected text with a tab. So is there a way to do tab and de-tab lines of code in textmate?
Indent: Alt+Tab
Un-Indent: Shift+Alt+Tab
the hotkey is command-left bracket to move left and command-right bracket to move right
(the buttons next to 'p')
heres a link to more hotkeys and such
http://projects.serenity.de/textmate/tutorials/basics/
You can use Shift+Tab to decrease indent; You just need to make and assign a macro. You can reuse this technique to accomplish a great many things.
Enter some text, and intend them, this is mostly for feedback.
Click the Record Macro Button
Use ⇧+⌥+⇥ (aka; Shift + Option + Tab) to decrease the indentation.
Click the record button to stop recording the macro.
Use the Edit menu or ⌃+⌘+M to save your macro;
Saving will prompt you to create a new bundle*, or add your macro to an existing bundle.
Add a Key Equivalent by clicking in the field and pressing ⇧+⇥
Your bundle-macro should look like the one below, simply Save and you're done! TextMate will now decrease indent on ⇧+⇥
*: (as noted by u/PatrickT) Sadly the create new bundle functionality has not yet been implemented, and you must choose to add to an existing bundle. You can still create a bundle via Bundles -> Edit Bundles then Command + N.
As an alternative, you can change the keybindings, see Link
Here is what I did:
Install Link
Go to File -> Open -> User Key Bindings, this will create/edit ~/Libary/KeyBindings/DefaultKeyBinding.dict
Add a binding, for the action enter shiftRight: (indent) manually (this is a TextMate specific action and not in the pre-populated actions list)
Choose a shortcut, I used cmd+alt+right
Do the same for the action shiftLeft: (un-indent, I used cmd+alt+left)
Save and then restart TextMate
I used a shortcut with arrow keys as my right hand is already on the arrow keys when I am selecting multiple lines, so this is a good fit.
The reason why I did it was because I have a german keyboard and alt+tab/alt+shift+tab don't work for me since I am using Witch for app-switching using these exact shortcuts.
EDIT: cmd+alt+left/right don't work when you have multiple tabs open, as they are used for navigate to next or previous tab in TextMate... seems this cannot be changed or overridden (I tried Setting Shortcut Keys in Textmate). Looking for an alternative shortcut now.
