Textmate tab and de-tab selected block - macos

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

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.

Disable chordal hotkeys so I can use a custom hotkey

How can I disable all default shortcuts that use key chords? I am trying to add custom shortcuts, but they do not work because there are dozens of shortcuts that use the keys that I want to use as 'key chords.'
I suppose I could find which ones use my keys and go through one by one to remove them, but that would be extremely tedious, since I can only view the command that use it in the 'used by' dropdown, which only shows a few commands at once. I would have to write each of those down, search for them individually, and then remove all the shortcut assignments associated with them.
The shortcuts I intend to use are "ctrl + R" and "ctrl + T", and map them to VS's 'Comment out selected lines' and 'Uncomment out selected lines' functions.
You can go ahead and assign CtrlR to Edit.CommentSelection. Under "Use new shortcut in:", select Text Editor. Visual Studio will automatically remove all hotkey key sequences that begin with CtrlR in the Text Editor context.
I had a similar problem (at VS 2017 (Left Arrow) was pressed. Waiting for second key of chord) and found Resharper's experimental Shortcuts Live View feature invaluable in reporting what actual shortcut had been assigned and are currently active. With that you can identify where a chordal kay has been assigned, and remove it. If you're using the latest Resharper, press the left Ctrl key three times in text editor.

how to come back when you are reading code in Xcode?

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.

How to indent my code in codeblocks?

What are the best code blocks short cuts ? Also is there some way we can directly indent all our code ? In addition how can we move through the active tabs in codeblocks ?
Tips about tab identation are helpful when you write your code from begining. But if you paste code in CodeBlocks from some external source, like PDF document, that code often will not have good identation.
In this case, you need to select code, right click on it, and choose Format use AStyle option.
This is a plugin for CodeBlocks for right text formatting.
I hope this will help someone!
You (these are the default settings I believe) can select a block of code and press the Tab key. This will indent the entire block.
So for indenting a whole file: Ctrl + A, then Tab.
In addition, you can use Shift + Tab on a selected block to "unindent"
You can move through the open tabs with Ctrl + Shift + Tab.
As for the best shortcuts:
I like Ctrl + D to duplicate a line and
Ctrl + L to copy it.
Anyway, you can set whatever shortkeys you like in the Editor menu (there you will also be able to find all shortkey currently set).
]2
Add shortcut as you wish from Settings->Editor->Keyboard shortcuts->plugins->Source code formatters(Astyle) or use Plugins->Source code formatters(Astyle)
CTRL+A to select the code and TAB for alignment.
I have not had much luck with the code formatter in C::B. I like my code to look like this...
if (blah..) {
SomeCode();
} else {
DifferentCode();
}
it allows more code to fit on a screen, and is still reasonably readable.
After trying to tweak the settings in Settings->Editor, then Source Formatter tab, when I went to format my code, it removed the if line entirely, and I have not been able to unset my tweaks to make it work.
Fornatually, ctrl-z still works.
The code formatter should never remove code, only play with white space.
Maybe there is a better plugin.
Mark.
In addition in How to switch between tabs in codeblocks.
codebocks 20.03
Linux (KDE Neon)
To switch between tabs.
Activate this with CTRL+SHIFT+TAB, then you can use the know options:
CTRL+TAB , to switch to the right tab.
CTRL+SHIFT+TAB , to switch to the left tab.
Or this other option, but this is not in the keyboard shortcuts, this option doesn't work in a cycle mode, when your get the last right tab, it jump to the bottom tabs:
CTRL+ right-arrow-key , to switch to the right tab.
CTRL+ left-arrow-key , to switch to the left tab.
Remember to activate with CTRL+SHIFT+TAB.
After you land in the desire tab you can type TAB to begin to start writing code.

Are these NotePad++ features available in TextMate?

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.

Xcode find caller functions

In Xcode, how can I find all caller functions of a specific function?
Xcode 4.5 (in beta) has this functionality. when you highlight say... a function, you can check the "caller" and "callee"
edit i believe it's located at the top left of the file panel for that file... so double click on the function to highlight it, and you click on on the file panel options (the one that has the "open recent, open unsaved...etc" drop down
EDIT #2
here's a picture to clarify (since i dont know what this menu button is called):
ALSO - XCode 4.5 is no longer beta, i believe, and is actually out in public
EDIT #3
also note that this caller thing does NOT search for being called under the performSelector method, as in, the particular caller that has this performSelector won't show up if you had done something like:
[self performSelector:#selector(checkIfShouldStopMovement) withObject:nil afterDelay:0.25];
In Xcode, the quickest method is this:
Select method in code (double click or mark using your mouse cursor)
Press Ctrl+1
Select "Callers" from the pop-up menu.
This is the shortcut for going View -> Editor -> Show Related Items in Xcode's menu.
use ⌘+Ctrl+Shift+H key combination on Xcode 7 onwards.
This can also be accessed via the assistant editor, as shown in the screenshot below. Whichever method you have the insertion point in in the main editor on the left will have its callers displayed in the assistant editor. I've found this to be the best way of looking through each caller in succession, since once you have "Callers" selected, you can then select the next caller via the next pop-up menu to the right in the jump bar.
In Xcode-7 you have the functionality of getting call-heirerchy. Right-click on the function and click "Find Call Hierarchy":
image reference:
Xcode 10 upwards seems to have made it easier. Just Command Click on the function and you should see it in the drop down.
Press ⌘+Ctrl+Shift+H shortcut when a method of interests is selected (with a mouse or cursor). (as per #uiroshan 's answer)
But you can also specify any another shortcut in XCode -> Preferences -> Key Bindings
Use Find in Project as Text or as Symbol.
AFAIK, there's no equivalent to e.g. Call Hierarchy known from Eclipse or NetBeans.
Strangely the refactoring tool can detect all method calls but not the search.
So I simply use it to rename my method to a unique name (eg. reset to resetPlayer) and then use the new name in a regular textual search.
1.) Menu > Edit > Refactor... > Rename to unique name
2.) search for the new name
The functionality is available in XCode 4.4.1, see this: http://smilingfinney.blogspot.de/2012/09/method-callers-in-xcode-44.html
