//! # Text Asset Parser
//!
//! This module reads line-separated text files from the embedded asset store (e.g. lists of blacklisted APIs or mnemonics)
//! and extracts them as vectors of whitespace-split strings.

use crate::core::{Asset, RbatError, Result};

/// Loads and parses a text file from the embedded asset compilation.
/// Splits lines into words/strings, filtering out extra whitespace.
///
/// # Errors
/// Returns `RbatError::MissingAsset` if the asset filename is not registered in the binary assets.
pub fn get_txt_from_file(file: &str) -> Result<Vec<String>> {
    let file = Asset::get(file).ok_or_else(|| RbatError::MissingAsset(file.to_string()))?;

    // converts bytes to string
    let content = String::from_utf8(file.data.to_vec())?;

    // inserts string from each line to texts vec
    let mut texts = Vec::new();
