reset-component-library initializes, i.e. empties the global
component library. Thus, the user can define a new set of component
resources from scratch. For example, sometimes it is convenient to
get rid of default symbols in the library window of
lepton-schematic and work only with those in your own custom
libraries.
Use the command before other component library commands, such as component-library.
Supposed you want some of your projects to use only special symbol libraries, then the typical usage is as follows. First reset all libraries, then populate the component library with your directories, e.g.:
(reset-component-library)
(component-library-search "${HOME}/lepton/symbols")
The good place to do so is gafrc in your project’s directory. However, you can also disable default libraries completely by writing such lines in gafrc in the directory with your user’s settings. See Legacy configuration files still in use for more information on configuration paths.
