use colored::Colorize;
use lyneate::Report;
fn main() {

"{} Mismatched match expression branch return types\n",
"Error:".bright_red()
);
let report = Report::new_char_spanned(
include_str!("basic.pseudo"),
[
(
29..102,
format!("{}", "In this match expression".dimmed()),
(255, 64, 112),
),
(
64..75,
format!("{} {}", "This is of type".dimmed(), "int".bright_white()),
(255, 159, 64),
),
(
87..92,
format!("{} {}", "This is of type".dimmed(), "string".bright_white()),
(207, 255, 64),

Usage
This crate provides:
- the
Report
struct which takes the source code and an iterator over the span, text, and color of all messages - the
Theme
,ThemeChars
,ThemeEffects
, andThemeSizing
structs which can be used to customize the appearance of a report display
Code spans can be byte-aligned or char-aligned. Different methods for constructing a Report
for either are provided.
The API is kept simple in order to allow as much flexibility as possible to the user. It does not make any assumptions or care about the provenance of the source code.
Planned Features
- Colorless support.
Structs
- A code report containing the source code in UTF32 and the spans, text, and colors of all messages.
- A collection of the themes to be used when displaying a report.
- Theme defining the characters used different components of the report display.
- Theme defining string callbacks applied to different parts of the report display.
- Theme defining the different lengths and paddings of the report display.
