The current default branch is
macros_with_lambda_quotes, which will eventually become the
only implementation. However, for a nicer printing of quotes, you may want to use the legacy branch
macros_old until prettier printing is implemented in this branch.
Installation instruction are the same as for the standard OCaml distribution.
You can find a few examples of what is possible in the links above, or on the
macros-examples repo. You can also
take a look at the
Installing OPAM packages
Most packages should compile fine, but causes that may break your packages include:
a use of the reserved words
macroas an identifier;
a use of
$as a regular operator.
If you need to install Camlp4, you will have to pin it to this repository. Please be aware that this version of Camlp4 is only provided for backward-compatibility and can only generate "pre-macro" OCaml, i.e. it cannot generate any of the macro constructs.
You are very welcome to try out macros. Please do report any bugs or inconvenience by opening an issue on this repo.
Found a bug and know how to fix it? We certainly appreciate pull requests. If you plan on making big changes, please file an issue first to discuss why theses changes are needed.
