Ansi Escape Sequence Parser
For a complete list of implemented sequences, see the documentation.
This is done through a pulldown type parser, where an iterator is exposed. This essentially turns all of the ANSI sequences into enums and splits the string at every location that there was an ANSI Sequence.
Example:
use ansi_parser::{Output, AnsiParser};
use ansi_parser::AnsiSequence;
fn main() {
//Parse the first two blocks in the list
//By parsing it this way, it allows you to iterate over the
//elements returned.
//
//The parser only every holds a reference to the data,
//so there is no allocation.
let parsed: Vec<Output> = "This is \u{1b}[3Asome text!"
.ansi_parse()
.take(2)
.collect();
assert_eq!(
vec![
Output::TextBlock("This is "),
Output::Escape(AnsiSequence::CursorUp(3))
],
parsed
);
for block in parsed.into_iter() {
match block {
Output::TextBlock(text) => println!("{}", text),
Output::Escape(seq) => println!("{}", seq)
}
}
}
no_std
support
no_std
is supported via disabling the std
feature in your Cargo.toml
.
Note
Register as hwatch-ansi-parser
in crate until the main unit version is updated.
