When you need to edit just one file without creating or loading the whole project in AppCode, you can use the LightEdit mode.
Keep in mind that the LightEdit mode works as a text-like editor, and it doesn't support the usual IDE editor features such as code completion, code navigation, or the autosave functionality. However, you can navigate to a specific line of code (⌘L), fold or unfold parts of code, check, and change file encoding.
Open a file in the LightEdit mode
You can use several ways to open a file in the LightEdit mode.
Open a file from the local file system
Locate the file you need in your file system, right click it and select Open With.
Select the version of AppCode with which you want to open a file and click Open.
Open a file from the command line
Open a file from the AppCode welcome screen
On the welcome screen, click Open or Import.
Select the file you need and click Open.
Work with code in the LightEdit mode
Even though the LightEdit mode doesn't support all of the AppCode editor coding assistance, you can still use basic editing features and basic menu options.
Use the main menu to open recent files, show the line numbers, whitespaces, extend the code selection, and so on.
When you edit a file, the blue color indication on the tab shows that the file content was changed.
Use the context menu for pasting or folding your code as well as switching to column selection mode.
Use the status bar to go to the line you need, check the VCS, or toggle the Autosave mode.
Turn on autosave
Click Autosave: off on the Status bar and select the Save changes automatically in the popup that opens.
Exit the LightEdit mode
You can quit the LightEdit mode and switch from editing a single file to working on the entire project.
Press ⌥⏎ and select Open file in project.
Alternatively, selectfrom the main menu.
