File system

The fs module enables interacting with the file system in a way modeled on standard POSIX functions.

Install#

To keep the core program simplified, the FS module is not included by the runtime, so you have to install it from npm.

npm install --save lichenscript-fs

Usage#

Read/Write data into buffer#

Read data from file:

import fs from "lichenscript-fs";

function main() {
  const content = fs.readFileContent("/tmp/foo.txt").unwrap();
  print(content);
}

Write data to file:

import fs from "lichenscript-fs";

function main() {
  fs.writeFileContent("foo.txt", "Hello World").unwrap();
}

Read/Write data into buffer#

import fs from "lichenscript-fs";

function main() {
  // Read data into buffer from file:
  const buffer = fs.readFile("/tmp/foo.txt").unwrap();
  print(content);
  // Write buffer to file:
  fs.writeFile("foo.txt", buffer).unwrap();
}

Unlink a file:#

import fs from "lichenscript-fs";

function main() {
  fs.unlink("foo.txt").unwrap();
}
