Using the learnings from my previous post I decided to create a bookmarklet which adds Steem Power next to all usernames. Great for whale scouting and curating.
Installation
Simply head over to steemlets.com and drag the "Show SP" button to your bookmarks bar. That's it!
Alternatively, create a new bookmark and add the following code as URL:
javascript:(function() { var isVisible = function(obj) { return obj.offsetWidth > 0 && obj.offsetHeight > 0; }; var curry = function(uncurried) { var parameters = Array.prototype.slice.call(arguments, 1); return function() { return uncurried.apply(this, parameters.concat(Array.prototype.slice.call(arguments, 0))); }; }; var getAndAddToCallbacks = function(socket, callbacks, method, params, callback) { callbacks.push(callback); var data = {id: callbacks.length - 1, method: method, params: params}; socket.send(JSON.stringify(data)); }; var runFun = function(funs, id, data) { funs[id](data); }; var socket = new WebSocket('wss://steemit.com/wspa'), callbacks = []; var getResult = curry(getAndAddToCallbacks, socket, callbacks), runCallback = curry(runFun, callbacks); socket.onopen = function(event) { getResult('get_dynamic_global_properties', [], function(data) { var totalVestingShares = data.result.total_vesting_shares.split(' ')[0], totalVestingFundSteem = data.result.total_vesting_fund_steem.split(' ')[0]; var nodes = [].slice.call(document.querySelectorAll('[itemprop=author] strong')).reduce(function(nodes, node) { if (!isVisible(node) || node.ssp__hasSp) { return nodes; } nodes.push(node); return nodes; }, []); var accounts = nodes.map(function(node) { return node.innerHTML; }); getResult('get_accounts', [accounts], function(data) { data.result.forEach(function(account, i) { var vestingShares = account.vesting_shares.split(' ')[0]; var steemPower = totalVestingFundSteem * (vestingShares / totalVestingShares); console.log(account.name + ' ' + steemPower); nodes[i].innerHTML = '' + account.name + ' [' + Math.round(steemPower) + ' SP]'; nodes[i].ssp__hasSp = true; }); socket.close(); }); }); }; socket.onmessage = function(event) { var data = JSON.parse(event.data); runCallback(data.id, data); }; })();
If you don't see your bookmarks bar you can enable it with Ctrl+Shift+B in Chrome.
Full uncompressed source code for the bookmarklet can be found here.
Let me know if you have any questions or comments!
