2/19/2023 0 Comments Scala replAfter reading and evaluating the expression from the command line interpreter it just print the output on the shell. ![]() Print: The third operation is to print the output.Immediately after reading the input, it perform its the next step that is to evaluate them correctly. Evaluate: The second operation that it performed Evaluate.So the first step it performs is reading the input from the command line shell. Read: When we type any input on the shell so it immediately start reading those inputs.Let’s have a look of its working in step see below: This is used to read the expression or we can say to evaluate the expression in scala. How does REPL Command Work in Scala?Īs we know that repl is an interactive interpreter shell. ![]() You will some lines of code automatically gets printed. Just open your command line interface and run this command there. This is the command that we have to run while working with repl in scala. Web development, programming languages, Software testing & others Please refer to Shutdown code described above in the standard method.Start Your Free Software Development Course Please note that new init code script should also contain necessary imports. This location can be overridden by the system property: org.os. Init codeīy default the initialization code will be loaded from $GS_HOME/tools/scala/conf/new-init-code.scala. Alternative method is used if system property org.os. is set as "yes', "on' or "true'. Should be placed in initialization code script (with import prefix added). The difference between the two methods is that the new one does not use a file with initial imports. Shutdown codeīy default the shutdown code will be loaded from $GS_HOME/tools/scala/conf/shutdown-code.scala. ![]() (empty lines and lines beginning with # are ignored) Init codeīy default the initialization code will be loaded from $GS_HOME/tools/scala/conf/init-code.scala. Initial importsīy default the initial imports will be loaded from $GS_HOME/tools/scala/conf/nf. Will be preceded by execution of shutdown code. GigaSpaces REPL during initialization phase will load imports from initial imports file and then execute init code. GigaSpaces 10.2 introduced alternative method to customize initialization code along with initial imports. It is possible to customize the initialization code, the shutdown code and the initial imports. Res3: = Command: val dataContent = res3.get Output: Now we'll execute a task using another helper method: Command: execute(gigaSpace) Output: Res0: .ProcessingUnit = use some helper method that is imported into the session scope (from .GigaSpacesScalaReplUtils) to get a GigaSpace proxy: Command: val Some(gigaSpace) = getGigaSpace("mySpace") Output: Gsm.deploy(new .SpaceDeployment("mySpace")) Output: We'll start by deploying a single space to the service grid, notice we already have an admin instance in scope to simplify this process.: Command: val gsm = Output: Type in expressions to have them evaluated. Welcome to Scala version 2.11.6 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_45). Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_45-b14) Start the shell $GS_HOME/tools/scala/shell.sh (or.It should be noted that this shell is a regular Scala REPL with some initial imports and initialization code. Following is a short demo of what can be done with the GigaSpaces scala shell.
