Heroku Integration with Amazon Q Developer Command Line

Today, we’re announcing the integration of the Heroku CLI with Amazon Q Developer. This integration, a result of our expanded Salesforce/AWS partnership, enables Amazon Q Developer command line suggestions of Heroku commands. This integration empowers Heroku users to auto-complete commands, thereby saving time and eliminating error-prone manual configurations of apps. Developers configure and manage their applications through a command line interface (CLI), especially during development when working within their integrated development environment (IDE). Heroku apps can be deployed in many different ways, and all that flexibility can be controlled through the CLI. This results in thousands of command options and…

CLI Flags in Practice + How to Make Your Own CLI Command with oclif

Editor's note: If you like CLIs, you should check out oclifconf taking place on Friday, May 31st in San Francisco. It’s the first community get-together for oclif! Space is limited so let us know soon if you are interested in joining. What is it that makes working from the command line so empowering? It can feel archaic at times, sure, but when you remember the right sequence of words, characters, and symbols for what you’re trying to do, it hits you with a sense of accomplishment and mastery over your tools that no graphical interface can compete with. So what…

Heroku CLI: Completing Autocomplete

The CLI Team at Heroku strives to create a CLI user experience that is intuitive and productive. We had “build CLI autocomplete” in the icebox of our roadmap for many years. But if we were going to ship it, it had to complement the existing CLI experience. This is challenging because the Heroku CLI is very dynamic: it comprises user installable plugins, and the data needed for completions is behind an API. Recently, we spent some time brainstorming the experience we wanted from Heroku CLI Autocomplete and decided it was time. We took “build autocomplete” out of the icebox and…

Announcing Heroku CLI Autocomplete for Bash and Zsh

Today we're excited to announce that Heroku CLI Autocomplete for Bash and Zsh is generally available. Heroku CLI Autocomplete makes your workflow faster and more seamless by helping you complete command and flag names when you press the tab key. Autocomplete completes all Heroku CLI commands and will automatically support new commands as they are added. You can also complete values for some flags and args—including apps, pipelines and config vars—so you won't need to run multiple commands to find and cross-reference them. We build the CLI first and foremost for human usability; Autocomplete takes usability a step further, making…

Open Sourcing oclif, the CLI Framework that Powers Our CLIs

It provides a structure for simple to advanced CLIs, including documentation, testing, and plugins for adding new commands. With oclif you can get up and…

Announcing the New Heroku CLI: Performance and Readability Enhancements

Today we are announcing the newest version of the Heroku CLI. We know how much time you spend in the CLI as developers and how much pride you take in being able to get things done quickly. Our new CLI has big improvements in performance as well as enhanced readability for humans and machines. Tuned for Performance CLI response time is made up of two parts: the API response time and the performance of the CLI itself, and the latter is where we’ve made big improvements. While a typical Unix user should experience responses that are around half a second…
