/**
|
|
* Class containing "advanced" configuration options.
|
|
*
|
|
* Options set here are for developer or advanced users only. If a general user
|
|
* needs to set one of these for normal KiCad use, either:
|
|
* * They are working around some bug that should be fixed, or
|
|
* * The parameter they are setting is of general interest and should be in the
|
|
* main application config, with UI provided.
|
|
*
|
|
* Options in this class are, in general, preferable to #defines, as they
|
|
* allow more flexible configuration by developers, and don't hide code from
|
|
* the compiler on other configurations, which can result in broken builds.
|
|
*
|
|
* Never use advanced configs in an untestable way. If a function depends on
|
|
* advanced config such that you cannot test it without changing the config,
|
|
* "lift" the config to a higher level and make pass it as parameter of the code
|
|
* under test. The tests can pass their own values as needed.
|
|
*
|
|
* This also applies to code that does not depend on "common" - it cannot
|
|
* use this class, so you must pass configuration in as proper parameters.
|
|
*
|
|
* Sometimes you can just use values directly, and sometimes helper functions
|
|
* might be provided to allow extra logic (for example when a advanced config
|
|
* applies only on certain platforms).
|
|
*
|
|
* For more information on what config keys set these parameters in the
|
|
* config files, and why you might want to set them, see #AC_KEYS
