How Vim's Go-to-Definition Failure in 2017 Led to the Creation of Rune
In 2017, a seemingly minor failure in Vim’s go-to-definition feature became the tipping point for a nine-year journey to build Rune, a new IDE. This breakdown wasn’t just a bug—it was a symptom of deeper issues in developer toolchains. The feature’s failure occurred due to underlying code or dependency changes, a common vulnerability in complex systems. When the mechanism that maps symbols to their definitions in the codebase broke, it disrupted the causal chain of code navigation → understanding → productivity. This observable effect—a developer unable to trace code efficiently—highlighted the fragility of relying on monolithic editors with brittle integrations.
The author’s response was not to patch Vim or switch to an existing IDE but to build a custom solution. This decision reflects a strategic trade-off: extending Vim or Emacs versus starting from scratch. Extending legacy editors risks inheriting their limitations, such as performance bottlenecks...
