Jen Gunter. You should see a new entry in package. The symbol tells npm to install the specific version we will be using for this tutorial. Running apm install lets Atom know to use our newly installed module. This function uses request to download the contents of a web page and logs the output to the Developer Console.
When the HTTP request completes, our callback function will be called with the response as an argument. Instead of reversing the selected text, fetch now treats the selection as a URL, passing it to download. Developer Tools make it easy to debug Atom packages. Any console. Ideally, we would like our download function to return the HTML as a string instead of just printing page contents into the console.
We will solve this problem by returning a Promise rather than the value itself. Promises allow us to return values obtained asynchronously by wrapping asynchronous logic in a function that provides two callbacks— resolve for returning a value successfully, and reject for notifying the caller of an error. We call reject if an error is returned by request , and resolve the HTML otherwise. In our new version of fetch , we get access to the HTML by calling then on the Promise returned by download.
This lets us insert the HTML into the editor. We also accept and handle any errors returned by calling catch. The next step involves extracting code snippets from the HTML of a StackOverflow page we obtained in the previous step.
We can greatly simplify our package implementation by assuming any such answer to be relevant and correct. This section assumes you are using the Chrome web browser.
You may be able to follow along using another browser, but instructions may change. You should see the accepted answer code snippets printed out in the console. The text function extracts and concatenates all text from the list of elements that would otherwise be returned by the previous query. This also strips out elements used for syntax highlighting purposes from the code. Our next step involves using the query we created to implement a scraping function using Cheerio , a jQuery implementation for server-side applications.
Our scraping function is implemented in just two lines because cheerio does all of the work for us! You can explore the entire Cheerio API in their developer documentation. If we run the command on a page with an accepted answer, it will be inserted into the editor:. Sometimes you may want the cursor to jump to the exact column position of the searched keyword. Just append another colon plus the column number:.
Editing a file is pretty straightforward. You can click around and scroll with your mouse and type to change the content. There is no special editing mode or key commands. If you prefer editors with modes or more complex key commands, you should take a look at the Atom package list.
There are a lot of packages that emulate popular styles. Atom doesn't just work with single files though; you will most likely spend most of your time working on projects with multiple files. You can open any number of directories from the command line by passing their paths to the atom command line tool. For example, you could run the command atom. When you open Atom with one or more directories, you will automatically get a Tree View on the side of your window.
The Tree View allows you to explore and modify the file and directory structure of your project. You can open, rename, delete and create new files from this view.
When the Tree view has focus you can press A , M , or Delete to add, move or delete files and folders. You can also right-click on a file or folder in the Tree view to see many of the various options, including all of these plus showing the file in Finder Windows Explorer your native filesystem or copying the file path to the clipboard. Like many parts of Atom, the Tree View is not built directly into the editor, but is its own standalone package that is shipped with Atom by default.
Packages that are bundled with Atom are referred to as Core packages. Ones that aren't bundled with Atom are referred to as Community packages. This is one of the interesting things about Atom. Many of its core features are actually just packages implemented the same way you would implement any other functionality. This means that if you don't like the Tree View for example, you could write your own implementation of that functionality and replace it entirely.
This will let you quickly search for any file in your project by typing parts of the path. This searches through your "buffers" or open files. The fuzzy finder uses the core. If you have a project with tons of files you don't want it to search through, you can add patterns or paths to either of these config settings or your standard. We'll learn more about config settings in Global Configuration Settings , but for now you can easily set these in the Settings View under Core Settings. It generates all files HTML, images, help project files and automatically integrates the help with the database.
