wpipe

Pipe the contents of one file into a command and write the result to another file, and do this every time the input file changes. Kind of like an extremely simple CLI for watchbuild.

Installation

$ npm install -g wpipe

Usage

wpipe <in> <out> <cmd>

Where <in> is a glob pattern or file path of the file to watch, <out> is the output file, and <cmd> is the command that is used to transform file contents.

Basically, all that wpipe does is execute something like this:

$ cat <in> | <cmd> > <out> # except you replace <in>, <out> & <cmd>
                            # with actual file names

Every time <in> changes.

API

wpipe(infile, outfile, cmd)

Start watching infile and transform its contents by piping them into cmd and write the result to outfile.
