"Are we GUI yet?" is a topic that frequently comes up within the Rust community. There are a lot of hard problems to solve, from the complexity of state management to something as easy to overlook as smooth resize. One problem I don't see discussed as often is a development and release pipeline that can handle the unique circumstances of each target platform. I met up with a bunch of application framework developers the day after RustNL to explore this problem and what can be done for it.| Ed's Home Page
Winnow is a parser-combinator library for Rust and 0.5 is now out. I last wrote about the 0.3.0 release, so I'll be covering all of the releases since then.| Ed's Home Page
With the release of rust 1.70, there was some surprise and frustration that unstable test features now require nightly, like all other unstable features in Rust. One of the features most affected is --format json which has been in limbo for 5 years. This drew attention to a feeling I've had: the testing story in Rust has been stagnating. I've been gathering my thoughts on this for the last 3 months and recently had some downtime between tasks so I've started to look further into this. The tl;...| Ed's Home Page

It is finally time to take the wraps off where I disappeared to over the last 6 months. Besides the family leave, I've mostly been chalking this up to working on toml_edit but one particular building block took up most of that time. I would like to introduce you to winnow, a fork of the venerable nom parser combinator library. For those that want to skip all the details, you can checkout the documentation and the migration guide and changelog. I would link to the docs but docs.rs seems to be ...| Ed's Home Page
toml v0.6 is now out with a new parser and renderer, addressing several existing issues and ensuring compliance with the TOML 1.0 compliance tests. This was done by leveraging the toml_edit crate.| Ed's Home Page
clap v4.1.0 is now out! See the changelog for more details.| Ed's Home Page
We are excited to (pre-) announce clap 4.0! This release focuses on removing deprecated APIs and finishing what we couldn't do without breaking changes. For more details see the CHANGELOG (including the migration guide) and the documentation. This release builds on work done in the 3.x releases and can be worth catching up on them: The 3.1 release The 3.2 release Or the v3 CHANGELOG.md for the over 50 patch releases since 3.0.0 To put all of this work into numbers: Baseline2.34.03.0.03.2.214....| Ed's Home Page
With excitement and trepidation, I'm announcing the release of clap 3.2. With clap 3.1, we discussed the need for a more open, extensible API and clap 3.2 represents one step in that direction. With two new builder API concepts, we are able to deprecate the following concepts: Arg::allow_invalid_utf8 Arg::validator, Arg::validator_os Arg::forbid_empty_values Arg::possible_values Arg::max_occurrences Arg::multiple_occurrences Command::args_override_self AppSettings::NoAutoVersion AppSettings::...| Ed's Home Page
clap 3.1 is here! Clap is a CLI argument parser for Rust and the v3.1 releases focuses on API cleanup slated for clap 4.0. See the CHANGELOG for details. clap 3.0 was in development for 4 years and though we saw comparisons to Half-life 3 in response to the release, we also saw people who cited the long gaps between breaking releases as a motivation for using it. For clap to stay relevant we feel we need to avoid the stagnation of long release cycles while keeping things smooth for the users ...| Ed's Home Page
Is adding a function in a patch release a violation of semver? Technically, yes but technical answers aren't always the right answers. This came up in a recent discussion focused on the relevant importance of setting the minimum patch version for a dependency. Some crates go so far as to never bump their minor version, like serde.| Ed's Home Page
I figured a great way to close out the year 2021 is to wrap up the long awaited clap 3.0 release! Some major milestones along the way: Jan 24, 2018: The first commit in the v3-dev branch Aug 30, 2019: StructOpt 0.3 is released with better clap integration May 03, 2021: v3.0.0-beta.1 is released Dec 08, 2021: 3.0.0-rc.0 is released Dec 31, 2021: 3.0.0 is released Thanks to: kbknapp, pksunkara, dpc, killercup, spacekookie, yosh, ldm0, and any other maintainers or contributors along the way Our ...| Ed's Home Page

Recently, there was an announcement for pushgen, a port of C++ transrangers to Rust with a follow up post from the author of transrangers. Seeing the performance numbers, I was curious what the experience was like with the different techniques compared in the followup and how the performance worked out in a real world application.| Ed's Home Page
liquid v0.20 resolves several planned breaking changes we've been holding off on. This doesn't make us ready for 1.0 yet but this closes the gap significantly. liquid-rust is a rust re-implementation of the liquid template engine made popular by the jekyll static site generator.| Ed's Home Page

I've been involved in the Rust community for about a year and a half now. What attracted me to Rust is that is looks like the first viable replacement for C++. It offers similar (actually better) protections than GCed languages and the full language is available in any environment, including exception-like error handling in the Windows kernel.| Ed's Home Page

I recently got the chance to redo the error handling in two different crates I help maintain. For liquid, I decided to write the error types by hand rather than use something like error-chain. In the case of assert_cli, I decided to finally give failure a try.| Ed's Home Page
