CamelHumps

CamelHumps in search commands

CamelHumps always works in all Navigation by Name commands, namely Search Everywhere/Go to 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:

ReSharper can also find CamelCased items that match letters in the query in any order:

Of course, such items will be placed lower in the results lists if there are items that match both letters and their order in the query.

CamelHumps in editor assistance actions

CamelHumps can also work for Extend/Shrink Selection and other 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. Select ReSharper | Options in the main menu.

2. Go to the Environment | Editor | Editor Behavior page of ReSharper options.

3. With the Use CamelHumps check box, 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, 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+W for the first time selects the current part of the word:

Only after pressing this keystroke for the second time ReSharper selects the whole word:

All subsequent presses are processed as usual.

With the Use CamelHumps option enabled, Visual Studio's 'Next/Previous Word' (Edit.WordNext/Edit.WordPrevious) and 'Extend selection to Next/Previous Word' (Edit.WordNextExtend/Edit.WordPreviousExtend) commands also work in a different way. When you press Ctrl+Right/Left,Arrow or Ctrl+Shift+Right/Left,Arrow the caret moves with/without selection 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.

There is also a way to have both behaviors (respecting and ignoring Camel Case) for 'Next/Previous Word' and 'Extend selection to Next/Previous Word', i.e. the default Visual Studio shortcuts (Ctrl+Right/Left,Arrow and Ctrl+Shift+Right/Left,Arrow) will work ignoring Camel Case and some custom shortcuts will work respecting Camel Case.
To configure it, turn off the Use CamelHumps option in ReSharper settings, and then assign custom shortcuts in Visual Studio options (Tools | Options | Environment | Keyboard) to the following commands:

• ReSharper_HumpNext – move caret to next hump

• ReSharper_HumpPrev – move caret to previous hump

• ReSharper_HumpNextExtend – extend selection to next hump

• ReSharper_HumpPrevExtend – extend selection to previous hump

Note that with this setup (with the Use CamelHumps option disabled), the Extend/Shrink Selection command will ignore CamelHumps.

CamelHumps in code completion

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

To change the way code completion filtering works with CamelHumps

1. Select ReSharper | Options in the main menu, then choose Environment | IntelliSense | Completion Behavior on the left.

2. Use the Match middle of the identifiers check box to toggle CamelHumps support for completion features.

3. 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.
