npm ‘is’ Package Hijacked in Expanding Supply Chain Attack
The ongoing npm phishing campaign escalates as attackers hijack the popular 'is' package, embedding malware in multiple versions.
args-tokenizer
Advanced tools
args-tokenizer
is a lightweight JavaScript library for parsing shell commands with arguments into an argv
array. This makes it easy to work with command-line tools and libraries that expect an array format for arguments, such as tinyexec
.
curl
-style commands. Made at Webstudio, open source website builder.
Install args-tokenizer
:
npm install args-tokenizer
Here's how you can use args-tokenizer
to parse shell commands:
import { tokenizeArgs } from "args-tokenizer";
const args = tokenizeArgs(`ls -la "./src"`);
console.log(args); // ["ls", "-la", "./src"]
args-tokenizer
also supports multiline commands, such as:
const args = tokenizeArgs(`
curl \\
-X POST \\
"https://my-url.com"
`);
console.log(args); // ["curl", "-X", "POST", "https://my-url.com"]
tinyexec
One common use case is passing more human-readable commands into the tinyexec
library:
import { tokenizeArgs } from "args-tokenizer";
import { x } from "tinyexec";
const [command, ...args] = tokenizeArgs("ls -la");
const result = await x(command, args);
console.log(result.stdout);
tokenizeArgs(command: string, options: Options): string[]
Parses a shell command string into an array of arguments. Properly handles:
'"./path/to/file"'
).\"
).\\
).loose
: If true
, the tokenizer will not throw an error when closing quotes are missing. Default is false
.// Without loose option (default behavior)
// This will throw an error due to the missing closing quote
tokenizeArgs('command "arg1 arg2');
// With loose option enabled
const args = tokenizeArgs('command "arg1 arg2', { loose: true });
// ['command', 'arg1 arg2']
