If you already have access to your Document class from your workspace (Using Workspaces) it is easy to access the root of your Syntax tree. Document document = ... // Get document from workspace or other source var syntaxRoot = await document.GetSyntaxRootAsync();

You can easily navigate the a Syntax Tree using LINQ. For example it is easy to get all the ClassDeclarationSyntax nodes (declared classes), that have a name starting with the letter A: var allClassesWithNameStartingWithA = syntaxRoot.DescendantNodes() .OfType<ClassDeclarationSyntax>()...

The CSharpSyntaxWalker class is out of the box implementation of the Visitor pattern, that we can use to traverse our Syntax Tree. Here is a simple example of a Syntax Walker that collects all the struct-s that have a name, starting with the letter A: public class StructCollector : CSharpSyntaxWa...

Each individual connection can be accessed via the connection method on the DB facade, even when there are multiple connections defined. The name passed to the connection method should correspond to one of the connections listed in the config/database.php configuration file: $users = DB::connection...

Prerequisite This guide assumes you have already used BuildTools and have run the Spigot server at least once. It also assumes that you have the Spigot-API jar file which we will use. 1) Start Eclipse; you may change the workspace location if desired. 2) Create a new Project Set the project na...

Replace operator: The -replace operator replaces a pattern in an input value using a regular expression. This operator uses two arguments (separated by a comma): a regular expression pattern and its replacement value (which is optional and an empty string by default). "The rain in Seattle&quo...

If you package your application in a jar using the maven-jar-plugin or the maven-assembly-plugin, an easy way to get the current pom version is to add an entry in the manifest, which is then available from Java.

The other examples may be the best and most stable way to get a version number into an application statically. This answer proposes an alternative showing how to do it dynamically during runtime, using the maven maven-model library. Add the dependency: <dependency> <groupId>org.apac...

Design Patterns provide solutions to the commonly occurring problems in software design. The design patterns were first introduced by GoF(Gang of Four) where they described the common patterns as problems which occur over and over again and solutions to those problems. Design patterns have four ess...

Use one of GLib.Value get methods (see valadoc documentation) or cast your value with the type of your value : public static void main (string[] args) { Value val = 33; int i = val.get_int(); int j = (int)val; } Note : if your current value doesn't contain desired type, GObject s...

This exemple shows how you can pass several types in function parameters : static void print_value (Value val) { print ("value-type : %s\n", val.type().name()); print ("value-content : %s\n\n", val.strdup_contents()); } public static void main (string[] args) { ...

In previous example, Value.strdup_contents prints GLib.DateTime as pointer address. You can register functions that will transform value to desired type. First, create a function that will have this signature : static void datetime_to_string (Value src_value, ref Value dest_value) { DateTime ...

The GLib.Task provide low-level API for performing asynchronous operations. var task = new GLib.Task (null, null, (obj, result) => { try { var ret = result.propagate_boolean (); } catch (Error err) { // handler err... } }); Later in a thread or a callback: t...
