pub struct BBCode {
    pub matchers: Arc<Vec<MatchInfo>>,
}

Expand description

The main bbcode system. You create this to parse bbcode! Inexpensive clones, since fields are all reference counted.

Fields§

§matchers: Arc<Vec<MatchInfo>>

Supply this!

Implementations§

source §

impl BBCode

source

pub fn default() -> Result<Self, Error>

Get a default bbcode parser. Should hopefully have reasonable defaults!

source

pub fn from_matchers(matchers: Vec<MatchInfo>) -> Self

Create a BBCode parser from the given list of matchers. If you’re building a custom set of tags, or merging [BBCode::basic()] with BBCode::extras() (and maybe more), use this endpoint

Examples found in repository ?

src/lib.rs (line 254)

255

    pub fn default() -> Result<Self, Error> {
        Ok(Self::from_matchers(Self::basics()?))
    }

source

pub fn to_consumer(&mut self)

Convert the current bbcode instance to one which consumes all tags it used to parse. The raw text SHOULD be left untouched (I think?)

source

pub fn get_tagregex(
 tag: &'static str,
 open_consume: Option<(i32, i32)>,
 close_consume: Option<(i32, i32)>
) -> (String, String)

Produce the two basic regexes (open and close) for bbcode tags

Examples found in repository ?

src/lib.rs (line 326)

    pub fn add_tagmatcher(matchers: &mut Vec<MatchInfo>, tag: &'static str, info: ScopeInfo, open_consume: Option<(i32,i32)>, close_consume: Option<(i32,i32)>) -> Result<(), Error> { //open_regex: String, close_regex: String) -> Result<(), Error> {
        let (open_tag, close_tag) = Self::get_tagregex(tag, open_consume, close_consume);
        matchers.push(MatchInfo { 
            id: tag, 
            regex: Regex::new(&open_tag)?, 
            match_type: MatchType::Open(Arc::new(info))
        });
        matchers.push(MatchInfo { 
            id: tag, 
            regex: Regex::new(&close_tag)?, 
            match_type: MatchType::Close,
        });
        Ok(())
    }

source

pub fn add_tagmatcher(
 matchers: &mut Vec<MatchInfo>,
 tag: &'static str,
 info: ScopeInfo,
 open_consume: Option<(i32, i32)>,
 close_consume: Option<(i32, i32)>
) -> Result<(), Error>

Add the open and close matches to the given vector for the given tag (you must construct ScopeInfo yourself). open_consume and close_consume are the amount of newlines to take before and after the open and close tag
