Hello everyone, Almost 10 years later, the [dead\_code\_analyzer](https://github.com/LexiFi/dead_code_analyzer) is coming back ! Thanks to all the more or less recent contributors and reviewers (I am not allowed to tag you all as a new user). The tool has been updated to **OCaml 5.2**. It is available on `opam`. There is planned work to update it to OCaml 5.3. There is planned work to offer a version compatible with OCaml 4.14. However, there is no intent to maintain the `dead_code_analyzer` on any OCaml version other than the latest. This static analyzer is a complement to the compiler’s warnings on unused code constructs. It reads **.cmi** and **.cmt** files, produced by using `-keep-locs` (on by default) on _.mli_ files and `-bin-annot` on _.ml_ files. It scans a compiled OCaml project and reports various warnings about suspicious code: - exported values never used, - class fields never used, - constructors and record fields never used, - optional arguments always or never used, - some stylistic issues. By default, only the 3 first elements of the above list are reported. More details available in the project’s _[README](https://github.com/LexiFi/dead_code_analyzer/blob/master/README.md)_. A more thorough documentation is in progress. --- _[View the full topic](https://discuss.ocaml.org/t/ann-dead-code-analyzer-1-0-0/17251)._
