Null checking is a very common task that ReSharper has always been helping to automate. Since the very first versions, ReSharper users had a whole bunch of context actions and quick-fixes at their disposal, such as Check parameter for null, Assert expression is not null and Check variable for null. As we're constantly improving the coding experience, we made a number of changes in previous releases: we extended the Check parameter for null action to check all parameters at once and also added an option to insert null checks when generating a constructor. ReSharper 2017.2 advances null check

With JavaScript’s continuous rise to fame, it only makes sense for us to continue improving JS support in ReSharper. The following is an exposition of some of the new ways in which ReSharper 8.1 makes JavaScript coding faster as well as safer. Completion Helpers via TypeScript When working with pure JavaScript files, it’s actually possible to improve ReSharper’s code completion functionality by including TypeScript type definitions in your libraries. In order to add this kind of support, you need first of all to search NuGet for DefinitelyTyped packages: Without the TypeScript annotat

The recording of our October 22nd webinar with Matt Ellis and Robert Demmer, Build Your Own Extension in ReSharper 8, is now available on JetBrains YouTube Channel and JetBrains.tv. This webinar is aimed at anyone interested in extending ReSharper. We’ll have a quick look at how to get started writing plugins, and talk about some of the more interesting extension points. Then we'll take a walk through an example of extending ReSharper without any code, using Live Templates and Structural Search and Replace patterns, from definition to packaging and distribution. Matt's presentation can be fou

Join us Tuesday, October 22nd, 14:00 – 15:00 GMT (10:00 – 11:00 EDT) for our free webinar, Build Your Own Extension in ReSharper 8 featuring Matt Ellis. ReSharper has always had many extension points for plugins to take advantage of. This webinar will look at how you can extend ReSharper not only by writing code, but also declaratively, with Live Templates, Structural Search and Replace patterns and ReSharper 8's NuGet-based extension manager. This webinar is aimed at anyone interested in extending ReSharper. We'll have a quick look at how to get started writing plugins, and talk about s

This is the second part of a previous post on Searching for Patterns in HTML using ReSharper 6. In the first part we covered the basics of searching for HTML tags, including the use of CSS selectors, using Structural Search and Replace. In this second and final post, we are going to put what we have learned to use, to not only allow us to replace our findings, but also as a means of extending ReSharper with custom patterns, which is the core idea behind Structural Search and Replace. Replacing tags The same dialog box that is used to search for patterns, can also be employed to replace patter

In ReSharper 5, we added a feature called Structural Search and Replace (SSR). You could think of it as a cross between Regular Expressions and Templating, with the added benefit that you don’t need to know RegEx to use it. The basic idea behind it is to allow you to extend ReSharper’s code analysis by defining custom patterns, and optionally providing quick-fixes (for replacing these with other patterns). In ReSharper 6.1, we extended SSR with support for other languages, specifically HTML and ASPX markup. Let’s take a look at how this can help us with web applications we work on. Searching

  One of the changes introduced with the new settings in ReSharper 6.1 is how importing and exporting of templates and custom patterns are done (Custom Patterns were previously known as Structural Search and Replace).  As part of the unification of settings, Templates and Patterns now fall under the same modus-operandi when it comes to importing and exporting as other settings do. This is very similar to how our IDEA based IDE’s such as IntelliJ, WebStorm et al. work. However, certain legacy functionality is also available depending on what needs to be done. The de-facto choice B

A new feature that has shipped with ReSharper 5 is the Structural Search and Replace. It is a way for us to locate certain patterns in our code, and optionally replace them. However, it is more than just a Find and Replace. It allows us to somehow extend ReSharper’s inspection settings by offering us means to identify patterns and highlight them. As many of you know, ReSharper offers a series of Suggestions, Hints, Warnings and Errors when it detects certain code patterns. For instance, when explicitly declaring a variable, ReSharper suggests you use var (and with good reason) These are

A while ago we introduced Structural Search and Replace, a new powerful feature in ReSharper 5 that lets you search for custom code patterns and replace them with other patterns, facilitating batch removal (or improvement) of stinky code. We were hoping to include a set of ready-to-use search and replace patterns into ReSharper 5.0 release but it just didn't happen. Instead, we're publishing a sample Pattern Catalog on the web site for you to download. The sample Pattern Catalog currently contains 17 patterns to search for and replace unreachable code, redundant compound assignments, clumsy me

Previous posts introducing ReSharper 5.0: Loops 2 LINQ Solution-Wide Warnings and Suggestions Call Tracking Value Tracking Structural Search and Replace is one of the most powerful yet less explored ReSharper 5.0 features. It allows you to find code that matches a structured template, parts of which may have certain restrictions. For example, you can set the type of the expression you are looking for, or specify the number of arguments. In addition to plainly finding parts of code that match the template, you can instantly replace them using an equally powerful replace template, or even co
