`spacer` is a simple CLI tool to insert spacers when command output stops.

If you're the type of person that habitually presses enter a few times in your

log tail to know where the last request ended and the new one begins, this tool

is for you!

## Installation

With Homebrew:

```bash

brew install spacer

```

Direct from Cargo:

```bash

cargo install spacer

```

## Usage

By default, `spacer` outputs a spacer after 1 second with no output. You can

change this with the `--after` flag.

```bash

tail -f some.log | spacer --after 5

```

`--after` accepts a number of seconds, and allows floating point numbers for

extra precision.

## STDOUT and STDERR

Some commands output most of their information on STDERR, not STDOUT. `spacer`

only monitors STDOUT, so if you find a situation where `spacer` doesn't seem

to be working it could be that the program you're piping from is using STDERR.

To "fix" that, redirect STDERR to STDOUT by using `2>&1` in your command:

```bash

my-command 2>&1 | spacer

```
