Structural Search

The XEmacs incremental search (I-search) feature has been extended in Harmonia-Mode by allowing you search for specific program features.

Using Harmonia's I-search

Original I-search

Just like with the XEmacs I-search, you can enter Harmonia's I-search mode by typing C-s (or C-r). The minibuffer will then display "I-search:". At this point, you can type any sequence of characters, and XEmacs will show you all strings in the current buffer that match the sequence you typed.

Harmonia-mode's I-search supports all the features of XEmacs' built-in I-search. For more information the built-in I-search, see the XEmacs User's Manual.

Harmonia's Filtered Searches

Harmonia-mode adds value to the regular I-search by allowing you to filter searches to return specific types of structures.

Each language has a variety of structure-types to which you can filter a search. There is a keybinding for each type, that you can use to toggle each type's filter.

• To filter the current search to a type of structure, enter the structure's filter command after entering I-search mode.
• Entering the command again will remove the filter.
• Entering the command for a different filter will remove the old filter before adding the new one.

Example: Cool

Cool supports the following filter commands:

To search for the next occurrence of a method with a name containing foo, type C-s M-m foo.

To search for the previous occurrence of the word bar in a comment, type C-r M-c bar.

Example: Java

Java supports the following filter commands:

To search for the next occurrence of a method with a name containing foo, type C-s M-m foo.

To search for the previous occurrence of the word bar in a comment, type C-r M-c bar.
