Python、JavaScript、PHP和C-Sharp RTF-Converter
RTF-Converter是一个函数，允许用户使用正则表达式将富文本格式（RTF）文件转换为纯文本。






功能

轻量级
快速高效
纯代码，无外部依赖



安装

克隆仓库
git clone https://github.com/ClankDev/RTF-Converter.git
cd RTF-Converter

使用pip安装
pip install rtf-converter

使用npm安装
npm i rtf-converter

使用composer安装
composer require clank-ai/rtf-converter



Python - 示例用法

将简单的RTF字符串转换为纯文本 

from rtf_converter import rtf_to_txt

# Sample RTF text
rtf_text = r"{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Helvetica;}}{\colortbl ;\red255\green0\blue0;}\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural\f0\fs24 \cf0 Hello, World!}"

# Convert RTF to plain text
plain_text = rtf_to_txt(rtf_text)
print(plain_text)  # Output: Hello, World!




Python - 示例用法 #2

将RTF文件转换为纯文本
从磁盘读取文件，使用rtf_to_txt函数将其内容转换为纯文本，然后将结果保存到新文本文件中 

from rtf_converter import rtf_to_txt

# Read RTF file
with open('sample.rtf', 'r', encoding='utf-8') as file:
    rtf_content = file.read()

# Convert RTF content to plain text
plain_text = rtf_to_txt(rtf_content)

# Save plain text to a new file
with open('output.txt', 'w', encoding='utf-8') as file:
    file.write(plain_text)

print("RTF has been successfully converted to plain text and saved as output.txt.")




Python - 处理RTF转换错误

如果RTF内容格式不正确，rtf_to_txt函数可能会抛出异常。以下是如何优雅地处理此类错误的示例 

from rtf_converter import rtf_to_txt

# Sample RTF text (potentially incorrect format)
rtf_text = r"{\rtf1\ansi\Hello, World!}"

# Attempt to convert RTF to plain text
try:
    plain_text = rtf_to_txt(rtf_text)
    print(plain_text)
except Exception as e:
    print("An error occurred during the conversion:", str(e))




JavaScript - 示例用法

将简单的RTF字符串转换为纯文本 

// Start test server (http-server)
// Save test javascript file as a module (.mjs)
// Import the rtfToTxt function from the rtf-converter npm package
import { rtfToTxt } from './node_modules/rtf-converter/rtf_converter.js';
    
// Sample RTF text
var rtfText = "{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033{\\fonttbl{\\f0\\fswiss\\fcharset0 Helvetica;}}{\\colortbl ;\\red255\\green0\\blue0;}\\pard\\tx720\\tx1440\\tx2160\\tx2880\\tx3600\\tx4320\\tx5040\\tx5760\\tx6480\\tx7200\\tx7920\\tx8640\\ql\\qnatural\\pardirnatural\\f0\\fs24 \\cf0 Hello, World!}";

// Convert RTF to plain text
var plainText = rtfToTxt(rtfText);
console.log(plainText);  // Output: Hello, World!




JavaScript - 示例用法 #2（带有错误处理）

将RTF文件转换为纯文本
从磁盘读取文件（或从服务器获取），使用rtfToTxt函数将其内容转换为纯文本，然后将结果保存到新文本文件中 

<!-- Start test server (http-server) -->
<!-- Save test javascript file as a module (.mjs) -->


<!-- TEST.HTML -->

<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>
<body>
    <h1>RTF Converter</h1>
    <input type="file" id="rtfFile" accept=".rtf" />
    <button onclick="convertRTF()">Convert RTF to Text</button>
    <script src="script.mjs" type="module"></script>
</body>
</html>




<!-- SCRIPT.MJS -->

// Import the rtfToTxt function from the rtf-converter npm package
import { rtfToTxt } from './node_modules/rtf-converter/rtf_converter.js';

// Function to handle the conversion process
function convertRTF() {
    var fileInput = document.getElementById('rtfFile');
    var file = fileInput.files[0];
    if (!file) {
    alert('Please select an RTF file to convert.');
    return;
    }

    // Read the RTF content from the uploaded file
    var reader = new FileReader();
    reader.onload = function(event) {
    var rtfContent = event.target.result;

    // Convert RTF content to plain text using the rtfToTxt function
    var plainText = rtfToTxt(rtfContent);

    // Save plain text to a new file
    var blob = new Blob([plainText], { type: 'text/plain' });
    var link = document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    link.download = 'output.txt';
    link.click();

    console.log("RTF has been successfully converted to plain text and saved as output.txt.");
    };
    reader.readAsText(file);
}

// Make the convertRTF function globally accessible so that it can be called from the HTML file
window.convertRTF = convertRTF;




PHP - 示例用法

将简单的RTF字符串转换为纯文本 

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

require_once 'vendor/autoload.php';

use RtfConverter\RtfConverter;

$rtfText = "{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033

    {\\colortbl ;\\red255\\green0\\blue0;\\red0\\green0\\blue255;}
    Hello, {\\f1\\b World}! This is {\\i italic} text. The — dash and the – dash are different.
    ‘ Quotes ’ are special too. Unicode: \\u8364 is the Euro symbol.
    Nested {\\b\\i bold and italic} text. Here's a list:
    \\list\\listtemplateid1\\listhybrid
    {\\listlevel\\levelnfc0\\leveljc0\\levelfollow0\\levelstartat1\\levelspace0\\levelindent0
    {\\*\\levelmarker\\fi-360\\li720\\jclisttab\\tx720 }{\\leveltext\\leveltemplateid1'\\uc0\\u8226 ;}
    {\\levelnumbers\\leveltemplateid2'\\u-3999 \\u8197 ;}}Hello from nested list!
    }";
    


echo "Before conversion\n";
$plainText = RtfConverter::rtfToTxt($rtfText);
echo "After conversion:\n";
echo $plainText . "\n";
echo "Type of output: " . gettype($plainText) . "\n";
echo "Length of output: " . strlen($plainText) . "\n";
?>

// Convert RTF content to plain text
$plainText = RtfConverter::rtfToTxt($rtfContent);

// Save plain text to a new file
