Work with source code | AppCode Documentation

When you work with code, AppCode ensures that your work is stress-free. It offers various shortcuts and features to help you add, select, copy, move, edit, fold, find occurrences, and save code.
For navigation inside the editor, refer to Editor basics.
If you do not remember a shortcut for the action you want to use, press Ctrl+Shift+A to find any action by name.
You can use the same dialog to find classes, files, or symbols. For more information, refer to Searching Everywhere.
If a file is read-only, it is marked with the closed lock icon in the status bar, in its editor tab, or in the Project tool window. If a file is writable, it is marked with the open lock icon in the Status bar.
Open file in the editor or select it in the Project tool window.
Do one of the following:
From the main menu, select File | File Properties | Make File Read-only or File | File Properties | Make File Writable.
Click the lock icon in the status bar.
If a read-only status is set by a version control system, it's suggested that you use AppCode version control integration features. For more information, see Version control.
In the editor, place the caret at the item you want to select and press Ctrl+W / Ctrl+Shift+W to extend or shrink your selection.
For example, in a plain text file, the selection starts within the whole word then extends to the sentence, paragraph, and so on.
If you need just to highlight your braces, place the caret immediately after the block closing brace/bracket or before the block opening brace/bracket.
In the Preferences dialog (Ctrl+Alt+S), go to Editor | General | Smart Keys.
Select the Use "CamelHumps" words checkbox.
If you want to use double-click when selecting according to capitalization, make sure that the Honor CamelHumps words... checkbox is selected on the Editor | General page of the Preferences dialog (Ctrl+Alt+S).
In the Preferences dialog (Ctrl+Alt+S), go to Editor | Code Style.
Select a language for which you want to configure the indentation.
From the options on the right, on the Tabs and Indents, select the Use tab character for the editor to use tabs when you press Tab, indent, or reformat code. You can also configure the tab size if you need. If you don't select this option, AppCode will use spaces.
You can use the standard shortcuts to copy Ctrl+C and paste Ctrl+V any selected code fragment. If nothing is selected, AppCode automatically copies as is the whole line where the caret is located.
By default, when you paste anything in the editor, AppCode performs "smart" paste, for example, pasting multiple lines in comments will automatically add the appropriate markers to the lines you are pasting. If you need to paste just plain text, press Ctrl+Alt+Shift+V.
When you copy (Ctrl+C) or cut (Ctrl+X) a line without any code selected, the paste action will add the contents of the clipboard to above the current line, not at your caret.
If you want to paste your copied code at the caret, select the Paste at the caret position option in the advanced settings.
Place the caret at a line or a symbol, right-click to open the context menu, select Copy/Paste Special | Copy Reference. When you select the Copy Reference (Ctrl+Alt+Shift+C) option, AppCode creates a reference string that includes the line number of the selected line or symbol. You can press Ctrl+V to paste the copied reference anywhere.
AppCode keeps track of everything you copy to the clipboard. To paste from history, in the editor, from the context menu, select Copy/Paste Special | Paste from History (Ctrl+Shift+V). In the dialog that opens, select your entry and click Paste.
The default number of items stored in the clipboard history is 100.
When you copy and paste code to the editor, AppCode displays the hidden (special) characters represented by their Unicode name abbreviation.
In the editor, place the caret at the characters you want to swap.
From the main menu, select Edit | Transpose.
There is no default shortcut for this action. You can assign a custom shortcut.
AppCode offers several useful shortcuts for manipulating code lines.
If you need to undo or redo your changes, press Ctrl+Z/Ctrl+Shift+Z respectively.
To add a line after the current one, press Shift+Enter. AppCode moves the caret to the next line.
To add a line before the current one, press Ctrl+Alt+Enter. AppCode moves the caret to the previous line.
To duplicate a line, press Ctrl+D.
To sort lines alphabetically in the whole file or in a code selection, from the main menu, select Edit | Sort Lines or Edit | Reverse Lines. These actions might be helpful when you work with property files, data sets, text files, log files, and so on. If you need to assign shortcuts to those actions, refer to Configure keyboard shortcuts for more information.
To delete a line, place the caret at the line you need and press Ctrl+Y.
To join lines, place the caret at the line to which you want to join the other lines and press Ctrl+Shift+J. Keep pressing the keys until all the needed elements are joined.
You can also join string literals, a field or variable declaration, and a statement. Note that AppCode checks the code style settings and eliminates unwanted spaces and redundant characters.
To split string literals into two parts, press Enter.
