Digiglass

Search Digi-Key from your terminal

Searching Digi-Key can be a pain. Here's a list of things I do every time I search for an item:

• Filter by "In Stock"
• Filter by "Quantity Desired: 1"
• Sort by price, ascending

Each of those actions takes a click and a couple seconds to load. I can automate these tasks and do most of the work from the command line.

Usage

• Search for blue LEDs:
  digiglass blue led
• Search for 470-ohm resistors in the through-hole category:
  digiglass -c 'through hole resistor' 470 ohm
• Browse all resistor kits:
  digiglass --category 'resistor kit'

-c and --category are interchangeable. Category names support fuzzy search - you can type part of the name and the proper category will probably appear.

Installation

This is a Python 3 script, so use pip3 to install:

pip3 install digiglass

Filters

Specify a filter to be used during a search like this: digiglass --filter some_new_filter

You can customize the filters used by Digiglass by modifying ~/.digiglass. It's a YAML file that looks like this:

filters:
    my_filter:
        in_stock: true
        lead_free: false
        rohs_compliant: false
        sort_by: '1000011'  # Unit price, USD, ascending
        min_quantity: 1
    pb_rohs:
        lead_free: true
        rohs_compliant: true

settings:
    default_filter: my_filter

Valid options are:

• in_stock: Item must be in stock
• lead_free: Item must be lead free
• rohs_compliant: Item must be RoHS compliant
• sort_by: The column by which to sort results
• min_quantity: At least this many of this item must be available

Every field in a filter is optional.

default_filter is used when no filter is specified.

Fields not specified in a requested filter use the default filter's settings.

Troubleshooting

Having issues? Try clearing the app's cache: digiglass --clear-cache

Still having issues? Odds are Digi-Key changed their HTML format. They probably broke the app's screen scraping. Let me know and I'll try and fix it—or dig in yourself! Screen scraping is fun.
