Tiny Content Framework

About the project

This is a tiny content strategy framework focused on goals, messages, and branding. This is not a checklist. Use what you need and scrap the rest. Rewrite it or add to it. These topics should help you get to the bottom of things with clients and other people you work with.

/**
 * Given an operation that produces a T, returns a Future containing the result of T, unless an exception is thrown,
 * in which case the operation will be retried after _delay_ time, if there are more possible retries, which is configured through
 * the _retries_ parameter. If the operation does not succeed and there is no retries left, the resulting Future will contain the last failure.

Intro

I've been working on a parser for a Haskell-like syntax called Duet. In the implementation I've taken particular care to make an awesome tokenizer and parser that is super helpful to learners.

Jasper Van der Jeugt made a talk about producing good error messages recently, which coincides nicely with my parallel work on this. So I thought I'd also share my

using rust pretty printers with rr

rr is a great debugging tool. it records a trace of a program's execution, as well as the results of any syscalls it executes, so that you can "rewind" while you debug, and get deterministic forward and reverse instrumented playback. it works with rust, but by default if you try it out, it could be pretty ugly when you inspect variables.

install

steps:

1. get the rust pretty printer python script
2. configure gdb to automatically load it
