GoKawiilPulsar, a new code-focused IDE for Pharo, unveiled at ESUG 2026
At ESUG 2026, a developer presented Pulsar, a new integrated development environment for Pharo built around staying close to the code rather than relying on generative-agent workflows. The presenter released the talk's slides and video online and described Pulsar as usable but still a work in progress, inviting feedback from users.
GoKawiil's interpretation of the reporting above, not reported fact.
The project reflects a broader argument that even as generative AI tools become more capable, developers still need direct visibility into and control over code rather than ceding that work to automated agents. Framing Pulsar this way positions it as a counterpoint to AI-driven rapid development tools, though its long-term adoption and feature set remain unproven given its early stage.
- Pulsar is a new IDE for Pharo introduced at ESUG 2026, emphasizing direct code interaction.
- The presenter argues that code-proximity tools remain important even as generative AI coding agents grow more common.
- Pulsar is still in active development, with slides, video, and the tool itself now publicly available for feedback.
