# RJL (Read JSON Log)

A Deno script that allows you to view JSON logs in a more readable manner. Logs can

either be loaded from a file or by piping them to stdin.

If you load multiple files at once, their lines are merged and each file is assigned

a separate color so you can differentiate them from each other.

The script expects each log line to have a `module`, `timestamp`, and `message` field.

Optionally, if a `level` field is present, it will be used for highlighting lines.

You can use the following options to filter logs:

```

Usage: rjl [options] [input-files...]

Arguments:

  input-files                The files to process

Options:

  -l, --level         Only shows logs with the given level (default: [])

  -s, --start-date     Filters out all logs before this date

  -e, --end-date       Filters out all logs after this date

  -m, --module       Only shows logs from the given module (default: [])

  -n, --not-module   Hides logs from the given module (default: [])

  -f, --filter      Filters out logs where the message contains the given string (default: [])

  --shallow                  Only show the first level of data keys

  -h, --help                 display help for command

```

## Installing RJL

RJL requires [Deno](https://deno.land) to be installed. You can then use

the following command to install the script:

```sh

deno install --allow-read -n rjl https://deno.land/x/rjl/cli.ts

```
