This also adds Python-2.0 to the list of accepted licenses. Lastly, it fixes a bug where the package.json files were incorrectly reordered. For the `exports` of a particular package, the order that the entrypoints are defined in is crucial. Therefore, we should not alter the order of entrypoints and instead maintain the originally defined ordering. We can use an `OrderedDict` to ensure that Python always loads the JSON files in the same order.

isBinaryFile
Detects if a file is binary in Node.js using ✨promises✨. Similar to Perl's -B switch, in that:
- it reads the first few thousand bytes of a file
- checks for a
nullbyte; if it's found, it's binary - flags non-ASCII characters. After a certain number of "weird" characters, the file is flagged as binary
Much of the logic is pretty much ported from ag.
Note: if the file doesn't exist or is a directory, an error is thrown.
Installation
npm install isbinaryfile
Usage
Returns Promise<boolean> (or just boolean for *Sync). true if the file is binary, false otherwise.
isBinaryFile(filepath)
filepath- astringindicating the path to the file.
isBinaryFile(bytes[, size])
bytes- aBufferof the file's contents.size- an optionalnumberindicating the file size.
isBinaryFileSync(filepath)
filepath- astringindicating the path to the file.
isBinaryFileSync(bytes[, size])
bytes- aBufferof the file's contents.size- an optionalnumberindicating the file size.
Examples
Here's an arbitrary usage:
const isBinaryFile = require("isbinaryfile").isBinaryFile;
const fs = require("fs");
const filename = "fixtures/pdf.pdf";
const data = fs.readFileSync(filename);
const stat = fs.lstatSync(filename);
isBinaryFile(data, stat.size).then((result) => {
if (result) {
console.log("It is binary!")
}
else {
console.log("No it is not.")
}
});
const isBinaryFileSync = require("isbinaryfile").isBinaryFileSync;
const bytes = fs.readFileSync(filename);
const size = fs.lstatSync(filename).size;
console.log(isBinaryFileSync(bytes, size)); // true or false
Testing
Run npm install, then run npm test.
