pad: command line text padding

Sometimes you have a command line sequence from which you need to cut some columns. Sometimes getting that command to work right requires that you previously tr -s ' '. Sometimes you have this solution all coded up before discovering the column -t command.

In that case, you need pad.

Usage

```text $ pad -h pad 0.1.0 Peter Goodspeed-Niklaus peter.r.goodspeedniklaus@gmail.com

USAGE: pad [OPTIONS]

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -a, --align ... Specify a column's alignment. May be repeated. -d, --delimiter Specify the delimiter with which to distinguish input fields -f, --file Read from the named file instead of stdin -s, --separator Specify the separator with which to separate output fields ```

If an input file is specified, that file is read. Otherwise, pad reads from standard input.

The input is split into columns according to the delimiter, and space-padded such that every column has consistent width. It is then output with the separator separating the columns.

Columns are aligned left by default, though column alignment may be set per column using the -a option:

The -a option must be specified once per column, and sets columns starting from the leftmost.

Examples

Basic usage

```sh $ ls -l | tr -s ' ' | cut -d' ' -f5,9 | pad

11469 Cargo.lock 216 Cargo.toml 0 README.md 512 src 512 target ```

Set column alignment

```sh $ ls -l | tr -s ' ' | cut -d' ' -f5,9 | pad -ar -ac

11469 Cargo.lock 216 Cargo.toml 0 README.md 512 src 512 target ```

Split and separate by a custom character

sh $ cat Cargo.toml | grep -Po "\d+\.\d+\.\d+" | pad -d. -s. -ar -ar -ar 0. 1.0 2.30.0 0. 1.1 0. 7.6 1. 2.0

Read from a file instead of stdin

```sh $ pad -f .gitignore -d'/'

       target

** *.rs.bk Cargo.lock ```

Split/separate on an equals sign:

sh $ pad -d = -f Cargo.toml -s = -ar | tail -n4 clap = "2.30.0" failure = "0.1.1" itertools = "0.7.6" unicode-segmentation = "1.2.0"
