| // Help manage multiple profiles, versions, extensions etc. |
| // |
| // These don't return error codes, as the presumption is parsing will |
| // always continue as if the tested feature were enabled, and thus there |
| // is no error recovery needed. |
| // |
| |
| // |
| // HOW TO add a feature enabled by an extension. |
| // |
| // To add a new hypothetical "Feature F" to the front end, where an extension |
| // "XXX_extension_X" can be used to enable the feature, do the following. |
| // |
| // OVERVIEW: Specific features are what are error-checked for, not |
| // extensions: A specific Feature F might be enabled by an extension, or a |
| // particular version in a particular profile, or a stage, or combinations, etc. |
| // |
| // The basic mechanism is to use the following to "declare" all the things that |
| // enable/disable Feature F, in a code path that implements Feature F: |
| // |
| // requireProfile() |
| // profileRequires() |
| // requireStage() |
| // checkDeprecated() |
| // requireNotRemoved() |
| // requireExtensions() |
| // |
| // Typically, only the first two calls are needed. They go into a code path that |
| // implements Feature F, and will log the proper error/warning messages. Parsing |
| // will then always continue as if the tested feature was enabled. |
| // |
| // There is typically no if-testing or conditional parsing, just insertion of the calls above. |
| // However, if symbols specific to the extension are added (step 5), they will |
| // only be added under tests that the minimum version and profile are present. |
| // |
| // 1) Add a symbol name for the extension string at the bottom of Versions.h: |
| // |
| // const char* const XXX_extension_X = "XXX_extension_X"; |
| // |
| // 2) Add extension initialization to TParseVersions::initializeExtensionBehavior(), |
| // the first function below: |
| // |
| // extensionBehavior[XXX_extension_X] = EBhDisable; |
| // |
| // 3) Add any preprocessor directives etc. in the next function, TParseVersions::getPreamble(): |
| // |
| // "#define XXX_extension_X 1\n" |
| // |
| // The new-line is important, as that ends preprocess tokens. |
| // |
| // 4) Insert a profile check in the feature's path (unless all profiles support the feature, |
| // for some version level). That is, call requireProfile() to constrain the profiles, e.g.: |
| // |
| // // ... in a path specific to Feature F... |
| // requireProfile(loc, |
| // ECoreProfile | ECompatibilityProfile, |
| // "Feature F"); |
| // |
| // 5) For each profile that supports the feature, insert version/extension checks: |
| // |
| // The mostly likely scenario is that Feature F can only be used with a |
| // particular profile if XXX_extension_X is present or the version is |
| // high enough that the core specification already incorporated it. |
| // |
| // // following the requireProfile() call... |
| // profileRequires(loc, |
| // ECoreProfile | ECompatibilityProfile, |
| // 420, // 0 if no version incorporated the feature into the core spec. |
| // XXX_extension_X, // can be a list of extensions that all add the feature |
| // "Feature F Description"); |
| // |
| // This allows the feature if either A) one of the extensions is enabled or |
| // B) the version is high enough. If no version yet incorporates the feature |
| // into core, pass in 0. |
| // |
| // This can be called multiple times, if different profiles support the |
| // feature starting at different version numbers or with different |
| // extensions. |
| // |
| // This must be called for each profile allowed by the initial call to requireProfile(). |
| // |
| // Profiles are all masks, which can be "or"-ed together. |
| // |
| // ENoProfile |
| // ECoreProfile |
| // ECompatibilityProfile |
| // EEsProfile |
| // |
| // The ENoProfile profile is only for desktop, before profiles showed up in version 150; |
| // All other #version with no profile default to either es or core, and so have profiles. |
| // |
| // You can select all but a particular profile using ~. The following basically means "desktop": |
| // |
| // ~EEsProfile |
| // |
| // 6) If built-in symbols are added by the extension, add them in Initialize.cpp: Their use |
| // will be automatically error checked against the extensions enabled at that moment. |
| // see the comment at the top of Initialize.cpp for where to put them. Establish them at |
| // the earliest release that supports the extension. Then, tag them with the |
| // set of extensions that both enable them and are necessary, given the version of the symbol |
| // table. (There is a different symbol table for each version.) |
