How to run gawk-mpfr

[mjcohen]

I have installed gawk-mpfr. I do not see how to run it. I have tried gawk-mpfr and gawk -M. Neither works.

Thanks

I don't know but the ​documentation says to use gawk -l mpfr.

The various gawk-xxx ports are all extensions for gawk. You can find out more, by running info for the extension(s) you have installed.

For example: info gawk-mpfr.

More generally, for any installed ports, you can list what items are installed:

$ port contents gawk-mpfr
Port gawk-mpfr contains:
  /opt/local/lib/gawk/mpfr.so
  /opt/local/share/info/gawk-mpfr.info

From that, you can see that a gawk library is installed, along with an info page.

Does that help?

Also, there is a homepage listed for each port. You can find that via website ports.macports.org:

​https://ports.macports.org/port/gawk-mpfr

Alternatively, you can find that by running port info <port>:

$ port info gawk-mpfr
