![]() IntelliSense provides smart completions that go beyond syntax highlighting and autocomplete. It uses variable types, function definitions and imported modules to provide intelligent completions. You can debug code directly from the editor. You can attach or launch your apps, and debug with breakpoints, call stacks and an interactive console. It's never been easier to work with Git or other SCM providers. The editor allows you to review diffs and stage files, as well as make commits. Pull and push from any hosted SCM service. Want even more features? To add languages, themes, debuggers and connect to other services, install extensions. Extensions are separate processes that don't slow down your editor. Microsoft Azure allows you to deploy and host your React (Angular), Vue, Node (and many more!) applications. Sites can store and query relational or document-based data and scale with serverless computing.īoost Note is a powerful collaborative workspace for developers that works at a light speed. Boost Note was designed to improve developers productivity by providing the best note taking experience for developers. ![]() This is not just a GitHub-flavored markdown. Diagrams created with Charts.js and Mermaid can be embedded in documents to increase visibility. To create your own Markdown editor, you can choose from keymaps such as Vim, more than 150 themes and many other options. Get an authentication token to access Boost Note's APIs through simple HTTP requests. ![]() Zapier allows you to automate your documentation with over 2,000 tool integrations. Work together with your colleagues to share information. All your teams can use the same shared workspace. Boost Note's realtime editing allows you to collaborate on documents. You can check the revision history of a document. In one click, you can roll back to the previous version. Granula access control is based on workspace. It is a core component of Emacs Lisp's interpreter. This Lisp dialect includes extensions that support text editing. Many file types can be edited using content-aware modes, including syntax coloring. You will find all the documentation you need, as well as a tutorial for novice users. Unicode support for almost all human scripts. You don't often see this variable either (come to think of it, you rarely see any of these variables), but you may see them in very short Ruby programs that process text.Emacs Lisp code and a graphical interface make it easy to customize. Their usage is similar, but what they really hold is very different. In Perl, $_ holds the value of the last statement and in Ruby it holds the string returned by the previous gets invocation. In Perl, the $_ variable means something similar, but totally different. This variable may be a point of confusion for those coming to Ruby from Perl. Again, the name of this variable is taken from the UNIX shells. ![]() If you must know the actual return value of the child process, you need to use this special global variable. The reason for this is simple: you can't get the exit status of child processes by their return value from the system method, only true or false. Of all the variables listed here, this is probably the most useful. $? - The exit status of the last child process executed.You may see them in smaller scripts where breaking the encapsulation rules is not an issue. But since these affect the behavior of all IO objects, they're rarely used, if at all. By default, these should be the newline character. When you read objects using gets and print them using puts, it uses these to know when a complete "record" has been read, or what to print between multiple records. ![]() $/ and $\ - These are the input and output record separators.However, this gets a bit more complicated when threads are involved, so be wary of using it blindly. Knowing one's own process ID is often useful in daemon programs (which run in the background, unattached from any terminal) or system services. $$ - The interpreter's process ID, denoted by $$ (two dollar signs).This is equivalent to the special ARGV array and has a less descriptive name, so it is rarely used. script.rb arg1 arg2, then $* would be equivalent to %w. $* - The command-line arguments in an array denoted by $* (dollar sign and asterisk).The name $0 mirrors the naming convention used in UNIX shell scripting for the same purpose. If this script requires script2.rb, $0 in that script file would also be script1.rb. So, if script1.rb was run from the command line, it would hold script1.rb. In other words, the script file that was run from the command line, not the script file that holds the currently executing code. $0 - This variable, denoted by $0 (that's a zero), holds the name of the top-level script being executed. ![]()
