So for sake of simplicity it was decided to remove it at all, leaving only a plain #if 0 handling, which is more or less stable and has pretty straightforward implementation. with unterminated blocks (opening/closing brace inside a preprocessor conditional). This is a really nice feature, however it is rather fragile and has many issues, e.g. The standard syntax highlights recognizes #else part after #if 1 conditional as a comment. tmPreferences files, see Packages/C Improved/Symbol Index (*).tmPreferences. The following scopes and default preferences are provided: Scope name You can adjust which symbols are available for navigation and visible in a symbol index or in an outline.
#SUBLIME TEXT 3 FOR MAC RO SOFTWARE#
However, most of major software projects implemented in C have their own internal libraries/frameworks and use some established patterns and idioms all across their sources. For example, a printf function is highlighted differently. The standard C package provides a special support for functions from C standard library and POSIX. It also allows, for instance, the whole macro body to be styled differently (this is up to a color scheme though). Scopes for preprocessor directivesĪll preprocessor directives provide a proper scope now ( meta.preprocessor), which means that you can select a whole macro with ctrl+ shift+ space or ⌘+ ⇧+ space.
Moreover, a function declaration which follows the macro ( int irq_attach(.)) is not recognized at all. This leads to incorrect highlighting and also adds a bogus symbol into the symbol list. In this example the standard C package recognizes check_range(.) inside a macro as a function definition though it is actually a function call.
#SUBLIME TEXT 3 FOR MAC RO CODE#
Macro innardsĪ macro body (with proper line continuations, if needed) is not able to contribute to the symbol index anymore, nor it can interfere with a code surrounding the macro, or anyhow break syntax highlighting.
See an issue about space-after-continuation highlighting. Standard Cīoth errors are ignored by the standard package, while C Improved highlights a premature closing paren in the first case as an error, and warns about trailing whitespaces after the backslashes (the second one is immediately followed by an error complaining about an unexpected EOL within macro parameters). vararg (but missing a preceding comma outside the comment) and accidentally putting tabs after some line continuation backslashes. Standard CĪnd below is a result of commenting out a msg. Here is an example of two more or less complex multi-line macros. Macro parameters (including variadic arguments) and argument stringification now have proper highlighting with handling of some common syntax errors. And so related issues were addressed first of all. Preprocessor issuesĬ preprocessor directives are relatively simple to parse (even with regular expressions, to some extent). This varies from enabling highlighting of operators to more complex enhancements listed below. Most of C Improved features tend to facilitate everyday C development experience. That is, it is not a self-sustained package, but only an addition (improvement) to the standard C++ package. Note that C Improved per se provides only the syntax definition among with some symbol indexing settings, nothing more. It is primarily focused on pure C overriding a standard syntax definition shipped with Sublime Text, though once installed it affects other C-family languages as well. This package provides better support of C/C++/Objective-C languages in Sublime Text.
