Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

powerline

v0.0.1

a powerline-style shell prompt builder

Readme

I was using @milkbikis's excellent powerline-style shell prompt when I decided that I wanted more options. Then I wanted a version in javascript instead of python so I could add those options myself in my current programming environment of choice. Then I started rewriting it. Then I observed that it was faster in javascript than in python, probably because node.js starts up really quickly.

This is the tragic result: a powerline-style shell prompt generator for node.

Installation

npm install powerline-js (speculatively because I haven't yet published this) or clone the repo. Symlink powerline.js to some location in your path.

Then go to the original most excellent project page and find a patched font you like.

Usage

Use it as you would the original. E.g, for bash:

function _update_ps1() {
   export PS1="$(~/bin/powerline.js $? --shell bash --depth 4)"
}
export PROMPT_COMMAND="_update_ps1"

For zsh:

function powerline_precmd()
{
   export PS1="$(~/bin/powerline.js $?)"
}
precmd_functions=(powerline_precmd)

Options

--shell [zsh|bash]
: which shell to emit color escapes for; defaults to 'zsh'

--cwd-only
: use only the current working directory in the prompt; defaults to false

--mode [patched|compatible]
: which font mode to expect; defaults to 'patched'

--depth *N*
: how many segments of the current working directory to show; defaults to 5

--no-repo
: do not attempt to show extra source repository information for the current directory; defaults to false

--repo-only
: generate only a source repository segment; defaults to false

Any further arguments are presumed to be $? aka the error returned by the previous shell command.

No mercurial support yet and the svn support isn't good, but then, you're using git anyway. Note that I default to zsh because that's how I roll, but the original defaults to bash.

TODO

  • An option to reverse the prompt direction, for use in zsh right prompts.
  • Mercurial support.
