I think xapply (man) is an awesome tool but compiling it takes a bit of effort because the code is using some custom .m files that are expandad to a bunch of source files using a tool called explode (man). Building also relies on some other custom tools like mk and mkcmd.

This repository contains the resulting C source files for xapply and two companion programs, xclate (man) and ptbw (man), together with BUILD files that makes building using bazel easier.

How to build the binaries:

bazel build -c opt xapply xclate ptbw

How to copy the binary to a destination (for example ~/local/bin/):

cp bazel-bin/{xapply/xapply,xclate/xclate,ptbw/ptbw} ~/local/bin/

The homepage of the tool is here: https://www.databits.net/~ksb/.

Many thanks to ksb (Kevin S Braunsdorf) for this tool.
