Its changelog records open-source licensing in 2001, years of compatibility work for Camlp4/Camlp5 and OCaml, and the addition of a user `.leditrc` binding file in version 2.00 on 2008-01-18. The GitHub-hosted continuation preserved the Inria codebase and kept it buildable for newer OCaml releases, including updates for recent OCaml versions in 2018, OCaml 5.0 build work in 2022, and opam/build fixes in 2025. ### Adoption history Ledit stayed in the Unix package ecosystem as a compact tool rather than a large application: the input package facts list Homebrew, Debian, MacPorts, Nix, and Ubuntu packaging. That footprint reflects the usual adoption path for small terminal helpers used by OCaml and command-line users. ### How it is used Users run `ledit` in front of another interactive command to get line editing, history navigation, reverse search, and configurable key bindings without changing the wrapped program. ### Why package nerds care For package maintainers, Ledit is an example of the old but durable terminal-helper class: tiny source, native-code language dependencies, man-page behavior, and recurring build-system updates to survive language-runtime churn. ### Timeline - 2001: Changelog records the addition of an open-source license. - 2008: Version 2.00 added support for a home-directory `.leditrc` or `LEDITRC` binding file. - 2018: Version 2.04 was distributed on the Inria page with updates for newer OCaml versions. - 2022: Version 2.06 updated the build for OCaml 5.0.0. - 2025: Versions 2.07 and 2.08 shipped build and opam maintenance fixes. ### Related projects - Ledit sits near other command wrappers and line editors such as `rlwrap`, but its implementation and packaging history are tied to OCaml, Camlp5, and Inria's OCaml ecosystem. ### Sources -
