The llr program reads a file or standard input, then it limits the length of the lines printed to fit to your terminals width by truncating the lines.

llr [flags] [filename]

The following flags are available:

• --width or -w: specifies the maximum width of the output. If not specified, the default is the width of the terminal.
• --debug or -d: enables debug output.

It also accepts an argument filename to read from, if this filename isn't specified or specified as -, it will read from standard input.

For example, to read the contents of a file named input.txt and print the lines to standard output with a maximum width of 50 characters, you can use the following command:

cat input.txt | llr -w 50

This may be more useful in programs that produce large and wide outputs where you don't always care about the end of the lines, such example may in some cases be output from =kubectl=.

You can build the llr program by navigating to the project directory and running the go build command:

go build -o llr

You can run the tests for the llr program by navigating to the project directory and running the go test command:

go test
