The Lookup References command is very similar to the Search Project command. In fact, each dialog box is identical. However, each dialog box has its own persistent state.
Find References To
Type the symbol name you want to locate. The word under the cursor is automatically loaded into this text box. Source Insight will use the context of the cursor position to determine the exact symbol instance you want. If you invoked Lookup References from a symbol dialog box or window, then Source Insight keeps the exact symbol references along with this text box.
Typically, you would type the name of an identifier in your program, however you can type any string here and a project-wide search will be performed. The search is very fast if you type a single word only.
Search In
This drop-down list contains a list of document types. You can use this list to restrict the search to only a particular type of file, or just the current file. If the Project Window is visible, then you can also use this list to specify the files selected in the Project Window.
Search Method
You can pick the search method to use from this list. There are four different searching methods available:
• Simple String
• Regular Expression interprets the pattern as a regular expression.
• Keyword Expression similar to an Internet search query.
• Lookup Reference searches for symbol references.
Lines of Context
This only applies if you selected the Keyword Expression search method. This specifies how closely, in number of lines, the keywords must occur in order to qualify as a match. See also “Keyword Expressions”.
Find word variations
If enabled, Source Insight will also find different ending forms of the keywords you specified. For example, if you specified the keyword “open”, Source Insight will also find “opens”, or “opened”, or “opening”. This option is only available for the Keyword Expression search method.
Search Options
Case Sensitive
Specifies whether the search is case sensitive or not.
Whole Words Only
For the Lookup References mode, this option is always on. If you choose a different search method, this will restrict matches to only whole words.
Skip Inactive Code
If enabled, then only code that is active under conditional compilation is searched. You must first specify known conditions in the Preferences: Languages dialog box, in order for Source Insight to know what conditions are active or not. Conditional compilation only applies to some languages.
Skip Comments
If enabled, then comments will not be searched.
Search Only Comments
If enabled, then only comments will be searched. This is mutually exclusive with the Skip Comments option. The comment options slow the search down a little.
Smart Reference Matching
This enables Source Insight’s smart reference matching feature. Source Insight will determine whether each reference found is actually referring to the symbol you are looking for.
The Smart Reference Matching option means that the search results will only contain references strictly to the exact symbol you specified. For example, if you select a member of a struct and look up its references, the search results will only contain references to that particular member of that particular struct – not just any string that is equivalent. Note that this option slows the process down because each same-string occurrence has to be qualified with a symbol lookup.
Touch files and cause recompile. Turn this on to cause each file’s “last modified” time stamp to be set to the current time. This is useful if you have a compile time dependency on an identifier usage. Just turn this on and search for references with this command. The places where the identifier is referenced will be “touched” and your make program or development system will recompile those files the next time you build your program.
