CamelHumps

CamelHumps is a feature that identifies parts of compound names composed according to CamelCase, where each part starts with a capital letter, or when parts of a compound name are separated by underscores. You can type only initial letters of these parts; ReSharper will find items with matching names automatically.

CamelHumps in search commands

CamelHumps always works in all Navigation by Name commands, namely Go to Everything/Type, Go to File, Go to File Member, and Go to Symbol. It is very convenient to type initial letters of name parts and get the list of matching items:

You can type either uppercase or lowercase letters:

CamelHumps in editor assistance actions

CamelHumps can also work for Extend/Shrink Selection and typing assistance commands that ReSharper overrides in Visual Studio:

  • Extend Selection to Next/Previous Word ( Ctrl+Shift+Right Arrow / Ctrl+Shift+Left Arrow)
  • Go to Next/Previous Word ( Ctrl+Left Arrow / Ctrl+Right Arrow)
  • Delete text from the start of the word to the caret (Ctrl+Backspace)
  • Delete text from the caret to the end of the word Ctrl+Delete

To enable CamelHumps in typing assistance actions

  1. On the main menu, choose ReSharper | Options .
  2. Go to the Environment | Editor | Editor Behavior options page.
  3. Use the Use CamelHumps check box to toggle CamelHumps support in typing assistance features.
  4. Click Save to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To drop-down list. For more information, see Managing and Sharing ReSharper Settings.

If the CamelHumps is enabled here, the Next/Previous Word command works in a slightly different way. When you press Ctrl+Right/Left,Arrow, the caret moves to the next/previous character that separates parts of a compound name in the current word, and only after the last part in word, it moves on to the next/previous word.

If the CamelHumps is enabled, the Extend/Shrink Selection commands take into account parts of compound names. Suppose you have placed the caret in the middle of a compound name with several parts that begin with uppercase letters:

ExtendSelection_CamelHumps_1
With CamelHumps, pressing Ctrl+W for the first time selects the current part of the word:
ExtendSelection_CamelHumps_2
Only after pressing this keystroke for the second time ReSharper selects the whole word:
ExtendSelection_CamelHumps_3
All subsequent presses are processed as usual.

CamelHumps in code completion

By default, CamelHumps support is also enabled in Code Completion features. I.e., you can start typing a CamelCase abbreviation of a symbol and the completion pop-up will display matched items. If necessary, you can disable this behavior.

To change the way code completion filtering works with CamelHumps

  1. On the main menu, choose ReSharper | Options.
  2. Go to the Environment | IntelliSense | Completion Behavior page.
  3. Use the Match middle of the identifiers check box to toggle CamelHumps support for completion features.
  4. Click Save to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To drop-down list. For more information, see Managing and Sharing ReSharper Settings.
