Find and replace in file

You can quickly find and replace text strings in the current document. Using different options, you can narrow your search process, use regular expressions in your search, and manage your search results.

Find the search string in a file

  1. Open your file in the editor.

  2. Press ⌃ F or select Edit | Find | Find from the main menu.

  3. In the search field that opens, enter your search string. AppCode highlights the results of your search in the file. Alternatively, in the editor, highlight the string you want to find and press ⌃ F. AppCode places the highlighted string into the search field.

Find the word at the caret

This command lets you find occurrences of the current word independently on its structural meaning — it can be anything in your document: an identifier or a keyword in the code, a word in a string literal or a comment, an XML tag or attribute, or even a number. If any matches are found, you can quickly navigate between them.

Note that this command is case-sensitive.

  • To find the word at the caret, choose Edit | Find | Next Occurrence of the Word at Caret from the main menu.

  • To go to the next or previous occurrence, press F3 or ⇧ F3, respectively.

Manage your search

AppCode lets you adjust your search process and perform various actions with the displayed search results.

  • If you want to see the list of previous searches, press ⌥↓ in the search field.

  • With the Regex icon selected, AppCode automatically escapes special regex symbols with backslash \ when you search for a text string by selecting it in the editor and clicking ⌃ F.

    Escape regex symbols

    For more details on regex, refer to the search with regex documentation.

  • Use the Previous occurrence and Next occurrence arrows to navigate to the previous or the next occurrence.

    Found Occurrences in the Find tool window

    Replacing all occurrences

  • You can narrow your search when you click the Words icon, the Match case icon in the search field, or click the filter icon to select a scope for your search.

  • You can press ^⌥X (previously known as ⌥G) to quickly toggle the Regex icon the Regex option. You can use regular expressions to opt for more challenging searches.

  • Press ⌃ F7 to see usages of any element in the opened file.

    If you don't want AppCode to highlight all found usages in the file, open the Preferences dialog (⌃ ⌥ S) and on the Editor | General page clear the Highlight usages of element at caret option.

    Press ⌥ F7 to search for usages beyond the current file or ⌃ ⌥ F7 to open the search results in a separate popup. If you need to configure some options before the search, press ⌃ ⌥ ⇧ F7 to open the Find Usages dialog.

Replace the search string in a file

  1. Press ⌃ R or select Edit | Find | Replace from the main menu to open the Replace in File window.

  2. In the top field, enter your search string. In the bottom field, enter your replacement string. If you need to preserve the case, click the Preserve Case icon located in the replace field.

    Replace in file pane

    Click Multi-line for a multi-line replace. For example, if you want to replace a comma with a comma and a new line, enter a comma in the search field and a comma and the new line in the replace field.

  3. Click Replace to replace items one by one, Replace all to replace all items in your file, and Exclude to omit some items from replacing.

The options that appear in the Replace window, are similar to the Find window and you can refer to the manage the search results section.
