Question

我有一条消息，可以说大约2k个字符，所以我如何分割消息，以便它将消息分段发送

示例“帮助”命令超过2000个字符

  if (!args[0]) {
    // Load guild settings (for prefixes and eventually per-guild tweaks)
    const settings = message.settings;

    // Filter all commands by which are available for the user's level, using the <Collection>.filter() method.
    const myCommands = message.guild ? client.commands.filter(cmd => client.levelCache[cmd.conf.permLevel] <= level) : client.commands.filter(cmd => client.levelCache[cmd.conf.permLevel] <= level &&  cmd.conf.guildOnly !== true);

    // Here we have to get the command names only, and we use that array to get the longest name.
    // This make the help commands "aligned" in the output.
    const commandNames = myCommands.keyArray();
    const longest = commandNames.reduce((long, str) => Math.max(long, str.length), 0);

    let currentCategory = "";
    let output = `= Command List =\n\n[Use ${settings.prefix}help <commandname> for details]\n`;
    const sorted = myCommands.array().sort((p, c) => p.help.category > c.help.category ? 1 :  p.help.name > c.help.name && p.help.category === c.help.category ? 1 : -1 );
    sorted.forEach( c => {
      const cat = c.help.category.toProperCase();
      if (currentCategory !== cat) {
        output += `\n== ${cat} ==\n`;
        currentCategory = cat;
      }
      output += `${settings.prefix}${c.help.name}${" ".repeat(longest - c.help.name.length)} :: ${c.help.description}\n`;
    });
    message.channel.send(output, {code:"asciidoc"});
  } else {
    // Show individual command's help.
    let command = args[0];
    if (client.commands.has(command)) {
      command = client.commands.get(command);
      if (level < client.levelCache[command.conf.permLevel]) return;
      message.channel.send(`= ${command.help.name} = \n${command.help.description}\nusage::${command.help.usage}`, {code:"asciidoc"});
    }
  }

任何简单的邮件拆分方法

我尝试了

let output = `= Command List =\n\n[Use ${settings.prefix}help <commandname> for details]\n`;
    let output1 =`` , output2 = ``;
if (output.length < 1900 )  output += `${settings.prefix}${c.help.name}${" ".repeat(longest - c.help.name.length)} :: ${c.help.description}\n`;
      else if (output.length > 1900){
        output1 += `${settings.prefix}${c.help.name}${" ".repeat(longest - c.help.name.length)} :: ${c.help.description}\n`;
      }
      else if(output1.length >1900 && output.length > 1900 ) output2 += `${settings.prefix}${c.help.name}${" ".repeat(longest - c.help.name.length)} :: ${c.help.description}\n`;

message.channel.send(output, {code:"asciidoc"});
    if(output1 !== ``) message.channel.send(output1, {code:"asciidoc"});
    if(output2 !== ``) message.channel.send(output2, {code:"asciidoc"});

及其可行的解决方案，但是还有比这更好的解决方案吗？
