CodeNav vs LMVTFY: What are the differences?
CodeNav: A browser extension that improves code navigation on Github. CodeNav is a Chrome extension and Firefox addon that makes navigating code on Github easier and more intuitive. It borrows features from popular IDEs for more seamless movement around code. Hover over a variable to highlight other references and visualize them on your scrollbar. Click a variable or object to search for other instances in the same project; LMVTFY: Automatically validate HTML for new issues and new issue comments on a given GitHub repository. LMVTFY is a service that watches for new issues and new issue comments on a given GitHub repository. If the comments contain (links to) live Web examples (e.g. a jsFiddle), the example's HTML is extracted and run thru the HTML5 validator. If there are any validation errors, LMVTFY then posts a comment (such as this one) on the issue pointing out these errors, so that the poster may correct them and/or realize the error of their ways.
