tmux vim navigation

I recently tried out the fantastic vim-tmux-navigator tmux plugin. Unfortunately, some the default key bindings conflict with some of the key bindings my fuzzy finder of choice uses. I wanted to remap them to the default vim split navigation commands that are prefixed with C-w, and found the solution of hjdivad in his gist. However, I wanted a simpler solution, so after some more digging I stumbled upon this reddit post and ultimately came up with the following solution, which doesn't rely on key bindings that unbind themselves, but uses tmux's 'key-tables'.

Last active August 29, 2015 13:56
Small helper function that enables you to drop collections based on their name. Use with caution!
function dropCollections (colName) {
var collectionNames = db.getCollectionNames();
for (var i=0,len=collectionNames.length; i<len; i++) {
var collectionName = collectionNames[i];
if(collectionName.indexOf(colName) == 0) {
db[collectionName].drop();
}
}
}

droustchev / mongodb_cloneCollection_helpers.js
Last active August 29, 2015 13:56
Small helper functions that enable you to easily clone collections that contain a date in the name (e.g. 'logs_2014-02-01') from one MongoDB instance to another.
function getDateString (date) {
year = date.getFullYear();
month = ('0' + (date.getMonth()+1)).slice(-2);
day = ('0' + date.getDate()).slice(-2);
return year + "-" + month + "-" + day;
}
function dateIterator (colBaseName, startDate, dayCount) {
var date = startDate
var i = 0;
