Remembering Bram Moolenaar: The Visionary Behind Vim and Open‑Source Charity

Bram Moolenaar (1961‑2023) was a Dutch programmer best known as the creator and lifelong maintainer of the Vim text editor.

He was born and raised in Lisse, Netherlands, and became an active member of the open‑source community. Vim, originally released as "Vi IMitation" in 1988 and later renamed "Vi IMproved," quickly became the preferred editor for developers and system administrators worldwide.

Beyond Vim, Moolenaar contributed other tools such as the AAP build system (a Python‑based make‑like utility) and the Zimbu programming language, whose "Hello, World!" example is shown below:

FUNC Main() int
  IO.print("Hello, World!")
  RETURN 0
}

From 2006 to 2021 he worked at Google’s Zurich office, balancing his job with Vim maintenance.

His family announced his passing on August 3, 2023, noting he died at age 62 after a rapid illness.

Moolenaar was also a pioneer of the “charity software” concept: Vim’s license encourages users to donate to the ICCF charity supporting Ugandan orphans. This model has inspired similar licensing strategies in other open‑source projects.

He received numerous honors, including an award from the Dutch Unix Users Group (NLUUG) on its 25th anniversary for his contributions to Vim and the broader open‑source ecosystem.

Christian Brabandt, a long‑time Vim contributor, recalled Moolenaar as a great leader who inspired the community through both technical excellence and charitable spirit, expressing deep regret at his early passing.
