Is it possible to bookmark a line in Xcode similar to the "mark" functionality in emacs? Also is there a shortcut used I can use to jump to a line number? My source code is becoming long and hard to navigate.
Yes; if you place the text caret on the line that you want to bookmark and select Edit > Add to Bookmarks (or ⌘D) you can add that line to the bookmarks in your project. You can then access these bookmarks from the Bookmarks item in the Groups & Files pane.
To go to a certain line, choose Edit > Go to Line... from the menu (or ⌘L), and type in the line number you want to navigate to.
I would also recommend that you use the #pragma mark directive to help you navigate around in source files. It takes the format:
#pragma mark <Label>
And will show up in the functions popup menu at the top of your source file; it makes it much easier to navigate around your code by grouping together common functions, improving the overall structure and readability of your code.
You can also use the "mark" key sequence, control-# or control-space, then you can use Delete to Mark (control-W), Select to Mark (control-X control-M), and Swap With Mark (control-X control-X). These emacs-like key bindings are supported in all Cocoa text views in Mac OS X, and you can customize the keybindings for Xcode in Xcode > Preferences > Key Bindings > Text Key Bindings.
You can bookmark an individual line in a file:
in your .emacs file
(global-set-key "\C-cb" 'bookmark-map)
sets it up, so:
control-c b m sets a bookmark (you can name it whatever you want.)
control-c b j jumps to a bookmark (it asks which bookmark you want)
Also:
(global-set-key [f1] 'goto-line)
sets F1 to ask for a line number and jump to that file

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.
For example, let's say I have three tabs open in vim:
1: nice_program.c
2: something_fun.h
3: super_script.sh
So if I hit some magic modifier key, and then type 'n' and hit enter I change tab to tab 1. Likewise, typing 'su' instead will navigate me to tab 3 instead.
Is such behavior possible? There are so many vim extensions, and I dont really get the whole vim extension lingo.
BTW, I am using gVim on XP and MacVim on OS X. Preferably the solution will work on both...
EDIT:
Note that I only want the incremental search to search across the names of the open tabs. That is, it's not supposed to actually search inside the tabs themselves.
Also, I never use buffers, it's tabs that I want this working for.
From the wording of the question it seems that you take the idea of tabs in
Vim not the way it is supposed to be taken by design of this feature. A Vim
tab page is not a form of a buffer or a window, it is a window layout
container, instead. No wonder there is no built-in way for switching to a tab
by the name of a buffer that is active (or the only one in its tab page, or
special in some other way). Semantically, that is switching to a buffer, not
a tab (but tab could be switched in order to show a buffer, if it is
necessary).
To switch to a buffer by its name use the :sbuffer command (:sb, for
short). It is not necessary to type the whole buffer name each time, since
the command has auto-completion. Usually one have to type only few letters of
a name to uniquely identify a buffer (the same way as you described
incremental search in the question).
By default, Vim open the requested buffer displacing one in the current
window. This behavior is governed by the switchbuf option. One of the
choices (called usetab) provided by that option allows to switch to a window
in another tab page if that window contains the buffer to edit. This is
exactly what suits your manner of work with tab pages.
To summarize, change the switching behavior as follows
:set switchbuf=usetab
and use the :sb command to open a buffer by typing a few letters of its name
and using Tab-completion.
I use this snippet I picked up in vim wiki to switch between open buffers (mapped to F5):
" switch between numbered buffers
:nnoremap <F5> :buffers<CR>:buffer<Space>
(put in your .vimrc file or whichever dotfile you use).
As for incremental search across open buffers, whenever I look up something using either /[something] or with */# on current word, it's automagically also highlighted in other buffers/tabs. Then I can switch buffers and hit n or N to move between matches in the currently viewed buffer. That's already baked into Vim.
Hope that helps.
The :set switchbuf=usetab solution given by ib never worked for me for whatever reason (even without loading plugins or my .vimrc) but :tab drop name-of-file works just the way you want (I found it on the Vim wiki).
Make it a custom mapping to save a few keystrokes with nnoremap <leader>t :tab drop.
Also I second ib's comment on the right and wrong way to use tabs in Vim.
I'm a NotePad++ user, new to TextMate.
There are some features that I really like in NP++ but couldn't figure out if TextMate support them.
Double click on a variable and have all instances highlighted
View 2 text windows side by side
Drag a file onto another opened Window
For this one, I don't know how to generate a screenshot ;-p. Basically, you can drag a file from Windows Explorer and drop it into NP++ to have it opened.
A lot of long time TextMate users are leaving TextMate land, actually. So, I'm not sure it's the right time to move to TextMate.
Emacs and Vim both do what you want and more. If you can afford the learning curve it's definitely worth it.
As for your question:
View 2 text windows side by side
You can have two or more windows for the same document. Assuming you are in a "project" right-click your file in the drawer and choose Open "foo.ext" in New Window. The two "views" contents are more or less in sync but doing cool things like columnar editing tends to break the syncing.
Due to how Mac OS X manages windows, the new window will probably be too large/too small and/or placed in a less than useful place. I use ShiftIt system wide to manage my windows and in such a case have them the same size side by side.
Double click on a variable and have all instances highlighted
What do you use this for? Is this visual highlight or non-contiguous selection?
Type ctrlw to select the word, then ⌘e to make the word your search term, then ⇧⌘f or Edit > Find > Find in Project… It will show all instances of the search term in another window. You can then "jump" to any occurence and do whatever you want.
If you only want to jump from occurence to occurence, select the word then type ⌘e then ⌘g to jump to the next occurence.
Another way is to type ctrls, a little text field appears at the bottom of your window where you can type a word and see its first occurence selected in real time. Repeatly typing ctrls will cycle through the occurences.
Drag a file onto another opened Window
You can drag & drop a file on TextMate's icon in the Dock. You can also right-click the file and choose Open with TextMate *or Open with…*. If you are in a "project" you can right-click and choose Add Existing Files…. Opening multiple files in TextMate will automatically create a "project" for you.
View 2 text windows side by side
I just tried this and it doesn't seem to recognize this functionality. the only time any sort of "add" icon came up was when I dragged the file into an open document and then released, but that resulted in adding the contents of the file into the document.
I just did a quick google search for "textmate split view" and it still doesn't seem to be supported according to some of the answers i found (one from macromates wiki).
Double click on a variable and have all instances highlighted
This also doesn't seem to be supported. This post suggests using the command + f (find), put the word into find, then command + g to jump to the next instance of that word.
There are definitely some things that can be added to textmate to make it more robust. If you are looking for something similar and are on a windows machine, you should check out e text editor. I loved that editor when I was working on a windows machine - split view is supported, but not sure about the highlighting. One thing that e also beats out textmate is the real time regular expression highlighting.
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.
In emacs I have various functions to manipulate text. Now that I'm using xcode, I suppose I could make emacs my default editor, but I want to browse obj-c objects and such, so I'd rather just implement my most used text manipulation commands for xcode.
First on my list, I'd like a command that moves the text of the current line up/down one line, keeping the cursor on the current line.
In emacs this is:
(defun move-one-line-downward ()
"Move current line downward once."
(interactive)
(forward-line)
(transpose-lines 1)
(forward-line -1))
I'd be happiest if I could write a script in Python that would do the equivalent in XCode, but as far as I can tell, I need to talk to AppleScript to do this.
Can someone walk me through how to do this with XCode?
Xcode 4 has a new set of command for moving the line where the cursor is or the selected text with command + option + [ or ]
⌥⌘[ or ⌥⌘]

What you’re wanting to do can be achieved through Xcode’s “User Scripts”—and it helpfully comes with a pair of scripts that almost do what you want. (I’m using Xcode 3.2 here, but I think these were also there in 3.1)
Look in /Developer/Library/Xcode/User Scripts/; there are two applescripts there, Move Line Up.scpt and Move Line Down.scpt. Here’s what’s in Move Line Up:
(*
To edit this script, choose Save As... and save it in your home directory, then re-add it to the User Scripts list.
*)
using terms from application "Xcode"
tell first text document
set {startLine, endLine} to selected paragraph range
if startLine > 1 then
set theText to (paragraphs startLine through endLine)
set theText to (theText as string)
delete (paragraphs startLine through endLine)
make new paragraph at beginning of paragraph (startLine - 1) with data theText
set selected paragraph range to {startLine - 1, endLine - 1}
else
beep 1
end if
end tell
end using terms from
These almost do what you want, except they select the whole line afterwards; I’m no applescript expert, but you probably want to store the selected character range. Have a look at the Xcode scripting dictionary (in AppleScript Editor, File -> Open Dictionary -> Xcode) to find out the types of objects you can manipulate.
You can add your own scripts to Xcode with the “Edit User Scripts”menu item in the script menu; and assign shortcut keys to the scripts in that window also, by double-clicking in the right-hand column beside the entry for the script menu item.
You can also use shell scripts (perl, python, bash, whatever) in the User Scripts menu, but these process only the selection or the whole file, so might be a bit heavyweight for moving a single line up or down.
See all the docuemntation on User Scripts here: http://developer.apple.com/mac/library/documentation/DeveloperTools/Conceptual/XcodeWorkspace/310-User_Scrips/user_scripts.html
I hope this helps!
I think your question is more generic that Xcode/emacs. Most IDE can't do stuff that editors can do and vice versa.
What I do is to use Xcode for 'simple' stuff and compile/debug. When I want to do lot's of coding (hm ... text editing) I open multiple files in one Vim (no offense to emacs ... vim is my editor of choice) and use all the vim tricks available.
I follow the same process when I need to do lots of coding on Windows (Visual Studio). I have VS opened just for compiling/debugging but I do most coding in separate Vim window.
I don't need to do any of that on Unix because I just open file in Vim and run Makefile from within Vim, jumping directly to errors and so on (:mak) ...
I'm sure that there are some extremely clever things to get Xcode do stuff that are already in Vim and Vim to do stuff that Xcode can do but I'm focusing on coding so not much time to play around.
Also, you can hook up emacs (or vi, or bbedit, or ed, I imagine) to xcode, so that they will talk to each other. When you tell xcode to open a file it will call emacsclient, etc. You can even get emacs to tell xcode where to put a breakpoint (I don't remember how, but I asked a question here a while back, and it works great)
