USAGE
|
|
-----
|
|
|
|
POST /
|
|
|
|
accepts raw data in the body of the request and responds with a URL
|
|
of a page containing the body's content
|
|
|
|
GET /<id>
|
|
|
|
retrieves the content for the paste with id `<id>`
|
|
|
|
GET /p/<id>
|
|
|
|
retrieves the HTML page with syntax-highlighted content for the paste with id `<id>`
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
Paste a file named 'file.txt' using cURL:
|
|
|
|
curl --data-binary @file.txt https://bin.wantguns.dev
|
|
|
|
Paste from stdin using cURL:
|
|
|
|
echo \"Hello, world.\" | curl --data-binary @- https://bin.wantguns.dev
|
|
|
|
Add this to your .zshrc to implement a quicker usage.
|
|
|
|
function paste() {
|
|
local file=${1:-/dev/stdin}
|
|
curl --data-binary @${file} https://bin.wantguns.dev
|
|
}
|
|
|
|
If the uploaded data binary is parsed as \"text/*\", then the paste will be syntax
|
|
highlighted
