Struct gpp::Context

pub struct Context {
    pub macros: HashMap<String, String>,
    pub inactive_stack: u32,
}

Context of the current processing.

Contains a set of currently defined macros, as well as the number of nested if statements that are being ignored; this is so that if the parser failed an if statement, and it is currently ignoring data, it knows how many endifs it needs to encounter before resuming reading data again. Only if this value is 0 then the parser will read data.

There are no limits on what variable names can be; by directly altering Context::macros, you can set variable names not possible with #defines. However, when replacing variable names in text the variable name must be surrounded by two characters that are not alphanumeric or an underscore.

Fields

macros: HashMap<String, String>

Map of all currently defined macros.

inactive_stack: u32

Number of layers of inactive if statements

Methods

impl Context

pub fn new() -> Context

Create a new empty context with no macros or inactive stack.
