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, and JetBrains Rider will find items with matching names automatically.
CamelHumps in search commands
CamelHumps always works in all Navigation by Name commands, namely Search Everywhere, 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 other typing assistance commands:
- Caret Move (Ctrl+Right/Ctrl+Left)
- Caret Move with Selection (Ctrl+Shift+Right/Ctrl+Shift+Left)
- Select Word at Caret (Ctrl+Alt+Right)
- Delete to Word Start/End (Ctrl+Backspace and Ctrl+Delete respectively)
- Double-clicking (if Honor "CamelHumps" word settings when selecting using double click is enabled on the settings page).
To enable CamelHumps in typing assistance actions
- Press Ctrl+Alt+S, or alternatively choose on Windows and Linux or on macOS.
- Go to the page of JetBrains Rider settings.
- With the Use CamelHumps check box, toggle CamelHumps support in typing assistance features.
- Click Save to apply the modifications and let JetBrains Rider 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 layer-based settings.
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: With CamelHumps, pressing Ctrl+Alt+Right for the first time selects the current part of the word: Only after pressing this keystroke for the second time JetBrains Rider selects the whole word: All subsequent presses are processed as usual.
- Move Caret to Previous Word in Different "CamelHumps" mode
- Move Caret to Previous Word with Selection in Different "CamelHumps" mode
- Move Caret to Next Word in Different "CamelHumps" mode
- Move Caret to Next Word with Selection in Different "CamelHumps" mode
- Delete to Word End in Different "CamelHumps" mode
- Delete to Word Start in Different "CamelHumps" mode
For example, If Use CamelHumps is enabled, the action Move Caret to Next Word in Different "CamelHumps" mode moves the caret to the end of word regardless of uppercase characters in this word; if Use CamelHumps is disabled, then the caret moves to the next CamelHump within this word.
These actions have no default keyboard shortcuts, and are not included in the menus but you can invoke them from Go to Action (Ctrl+Shift+A):
You can bind them with the shortcuts of your choice as described in the section Configuring Keyboard Shortcuts.
