gophgen

A simple placeholder & identicon generator

Placeholders are a necessity when writing web apps. Gophgen gives you a simple API for fast and autonomous placeholder creation right in your html.

Install

go get -u github.com/zelr0x/gophgen/...

Usage

Simply run the server at $GOPATH/bin/gophgen and type the localhost:port/parameters into src attribute of your img tags. Default port is 8080 but you can set it to any unreserved port on startup: gophgen 5555.

Change parameters to what you want that image to be.

Identicon specifier

• http://localhost:8080 - random 64x64 image
• http://localhost:8080/i - random 64x64 identicon

Size

Single number or two numbers separated by 'x' character:

• http://localhost:8080/250 - 250x250 image
• http://localhost:8080/240x100 - 240x100 image
• http://localhost:8080/i/85 - 85x85 identicon (use this format for identicons)

Color

One parameter for one color, two parameters for two colors (for identicons).

• http://localhost:8080/200/53f - 200x200 image with #5533ffff as its color.
• http://localhost:8080/i/120/099b8c/bc3a1abb - 120x120 identicon with background color #099b8cff and foreground color #bc3a1abb
• http://localhost:8080/i/64/53f/fuchsia - 64x64 identicon with colors #5533ffff and "fuchsia" (from x11 color palette) It's really flexible, just try other combinations.

Data

Want a unique identicon for a particular user? Just add some seed at the end:

• http://localhost:8080/i/128/099b8c/bc3a1a/d=UserName125 - 128x128 identicon with colors #099b8cff and #bc3a1aff for "UserName125"
