If you opt to go in and edit EDE project files directly—for
instance, by using C-c . e (see Customize Features)—you
must then “rescan” the project files to update the internal data
structures. To rescan the current project, type C-c . g
(ede-rescan-toplevel).
EDE can help you find files in your project, via the command
C-c . f (ede-find-file). This prompts for a file name;
you need not specify the directory. EDE then tries to visit a file
with that name somewhere in your project.
EDE can use external tools to help with file finding. To do this,
customize ede-locate-setup-options.
List of locate objects to try out by default. Listed in order of preference. If the first item cannot be used in a particular project, then the next one is tried. It is always assumed that ede-locate-base is at end of the list.
EDE also provides a project display mode for the speedbar (see Speedbar in GNU Emacs Manual). This allows you to view your source files as they are structured in your project: as a hierarchical tree, grouped according to target.
To activate the speedbar in this mode, type C-c . s
(ede-speedbar).
