danmactough / add-collaborator.sh
Created October 12, 2015 16:04
I needed to add a read-only collaborator to many repositories, and doing it via the website was really tedious
#!/bin/bash
GITHUB_TOKEN=$(git config --global github.token) # I've defined an API token in my git config -- ymmv
GITHUB_USER="" # the collaborator
REPO_OWNER="" # the owner of the repos
REPOS="" # space-delimited list of repositories
PERMISSION="pull" # may be one of "admin", "push" (i.e., read/write -- default), or "pull" (i.e., read-only)
for REPO in ${REPOS} ; do
curl -X PUT -i -d '{ "permission": "'${PERMISSION}'" }' \
-H 'Accept: application/vnd.github.ironman-preview+json' \
-H "Authorization: token ${GITHUB_TOKEN}" \

Not using this really clever bit
function () {
actions.zoomForPrint();
window.requestAnimationFrame(function () {
const imgData = getImageFromCanvas();
// atob to base64_decode the data-URI
const imgSrc = atob(imgData.split(",")[1]);
// Use typed arrays to convert the binary data to a Blob
const buffer = new ArrayBuffer(imgSrc.length);
var view = new Uint8Array(buffer);
