Inspecting JSON at the Command-Line

1 Comment

This is a simple tool to pull specific values out of JSON, or to pull JSON from JSON, at the command-line:

JsonPare

It’s useful to pull configuration values from within a Bash script.

Example data:

{"a": [9, 6, {"b": [99, 88, 77, "text", 55]}]}

Example commands:

$ cat example.json | jp a.2.b.3
"text"

$ cat example.json | jp a.2 | jp b.3
"text"

$ cat example.json | jp a.2 | jp -p b.3
text

Using the “Tig” Git Console UI

At its simplest, Tig allows you to navigate your Git projects from the console (it internally invokes commands to git). It has nearly all of the browsing functionality of Github while readily running locally. At it’s most-complicated, it looks to be as flexible as Git itself.

The two simplest ways to run Tig (from within our Git project):

  • Piping: git log | tig
  • Calling directly: tig

In the case of piping, you’re really just benefiting by coloring the output and pumping it through pagination. If you’re going to call Tig directly, the experience will be more interactive. The default “view” is the log.

You can also specify other views:

$ tig -h
tig 1.2.1 (Nov 29 2013)

Usage: tig        [options] [revs] [--] [paths]
   or: tig log    [options] [revs] [--] [paths]
   or: tig show   [options] [revs] [--] [paths]
   or: tig blame  [options] [rev] [--] path
   or: tig stash
   or: tig status
   or: tig <      [git command output]

Options:
  +<number>       Select line <number> in the first view
  -v, --version   Show version and exit
  -h, --help      Show help message and exit

A Console-Based Form

I just uploaded a Python tool called “text-prompts” that takes a dictionary, presents a list of prompts to the user, and returns a dictionary.

For more detail, go here: text_prompts.txt

Example:

    from text_prompts import text_prompts
    text_prompts({ 'prompt1': ('Prompt 1', True, None), 
                   'prompt2': ('Prompt 2', False, 'default')})

Output:

    Prompt 1 (req): first response
    Prompt 2 [CTRL+D for "default"]: second response

Result:

    {'prompt1': 'first response', 'prompt2': 'second response'}
