PHP exceptions and errors

In PHP, Exceptions can be caught:

try {
    throw new \DomainException('input out of bounds');
} catch (\Exception $e) {
    echo "got exception\n";
} finally {

title_case.ts

Usage example:

import { titleCase } from "https://gist.githubusercontent.com/crabmusket/cd10f732e847afd023a00f6a45bd0d72/raw/558463e1c2a5aa910915a21396b105cefd1254d9/title_case.ts";

console.log(titleCase("deno is AWESOME"));
console.log(titleCase("words-can contain_punctuation"));
console.log(titleCase(" spacing is preserved"));

semaphore.ts

An asynchronous semaphore utility class meant to work with Deno. You can use it to implement rate-limiting and other concurrency patterns.

Usage example:

import { Semaphore } from "https://gist.githubusercontent.com/crabmusket/681b4f81ed05716f8dd10ac88d1d960b/raw/5e7c18013e896425d1048324f8668932f23437df/semaphore.ts";

Deno micro modules

Each of these modules is a single file consisting of no more than a page or two of code, which provide some useful 'generic' feature. These modules could be copied as-is into any TypeScript project, but they're designed to work with Deno. Deno's URL loading makes it very easy to import them.

semaphore.ts, an async Semaphore class
json.ts, a JsonValue type and utility functions
title_case.ts, convert strings to 'Title Case'

deno_env_file.ts

Use this snippet to parse, modify and render environment files.

import { EnvFile } from "https://gist.githubusercontent.com/crabmusket/e10effe4800691bb15543ff264518e76/raw/deno_env_file.ts";
