rsc-archiver

压缩和解压缩 runescape classic .jag/.mem 缓存文件。 这些文件 包含一个描述档案大小的专有标题,以及 每个单独的条目(文件)。 文件名存储在一个“哈希”中,所以它是 没有暴力破解就不可能恢复原件(除非他们在 ~5 个字符)。

该模块适用于浏览器和节点。

  --version  Show version number                                       [boolean]

example

const fs = require('fs');
const { JagArchive } = require('./src');

let rawJag = fs.readFileSync('./data204/sounds1.mem');
let archive = new JagArchive();
archive.readArchive(rawJag);
console.log(`cache has ${archive.entries.size} files`);
fs.writeFileSync('death.pcm', archive.getEntry('death.pcm'));

const testArchive = new JagArchive();
testArchive.putEntry('test.txt', Buffer.from('test string'));
fs.writeFileSync('./data204/test.jag', testArchive.toArchive(true));

rawJag = fs.readFileSync('./data204/test.jag');
archive = new JagArchive();
archive.readArchive(rawJag);
console.log(`cache has ${archive.entries.size} files`);
console.log(archive.getEntry('test.txt').toString());

api

archive.entries

哈希图 -> 解压缩的文件缓冲区。

archive = new JagArchive()

创建一个新的 jag (de)compressor 实例。

archive.readArchive(buffer)

解压缩缓冲区并用其中的每个文件填充条目。

archive.hasEntry(name)

检查存档是否包含基于哈希或文件名的条目。

archive.getEntry(name)

根据名称或散列返回条目。

archive.putEntry(name, buffer)

将文件添加到存档缓冲区。

archive.removeEntry(name)

根据名称或散列删除条目。

archive.toArchive(individualCompress=true)

将条目压缩到 jagex 存档。 如果 individualCompress 为真,bzip 每个 单独归档。 否则,连接所有文件然后 bzip 而是那个结果。

rsc-archiver

compress and decompress runescape classic .jag/.mem cache files. these files contain a proprietary header describing the size of the archive, and of each individual entry (file). filenames are stored with a "hash" so it's impossible to recover the originals without bruteforcing (unless they're under ~5 characters).

this module works in the browser and node.

api

archive.entries

Map of hashes -> decompressed file buffers.

archive = new JagArchive()

create a new jag (de)compressor instance.

archive.readArchive(buffer)

decompress buffer and populate entries with each file within.

archive.hasEntry(name)

check if archive contains entry based on hash or filename.

archive.getEntry(name)

return entry based on name or hash.

archive.putEntry(name, buffer)

add a file to the archive buffer.

archive.removeEntry(name)

remove entry based on name or hash.

archive.toArchive(individualCompress=true)

compress entries to a jagex archive. if individualCompress is true, bzip each file separately. otherwise, concatinate all of the files and then bzip that result instead.
