Randomness

Rather than going to random.org or making up your own random data, you can now insert random numbers, UUIDs, names, IP addresses, and much more using an IntelliJ action!

This plugin is also available on the plugin repository!

📖 How to use

To insert random data, press Alt + R (or ⌥R) to open the list of available templates and choose one that suits your task. By default, a different value is inserted at each caret.

You can modify this behavior by holding a key while selecting the type of data to insert:

• Array: Hold Shift to insert a customisable array of values.
• Repeat: Hold Alt (or ⌥) to insert the same value at each caret.
• Settings: Hold Ctrl to open the settings of that data type.

You can hold multiple modifier keys to combine their effects.

Randomness can also be found in the main menu under Tools or in Code > Generate.

✨ Features

• 🕸 Data Types
  There are six basic data types that can be inserted and customised:
  1. Integers, such as 7,826,922, from a custom range, in any base from binary to hexatrigesimal.
  2. Decimals, such as 8,816,573.10, using customisable separators.
  3. Strings, such as "PaQDQqSBEH", with support for reverse regex.
  4. Words, such as "Bridge", with predefined or custom word lists.
  5. UUIDs, such as 0caa7b28-fe58-4ba6-a25a-9e5beaaf8f4b, with or without dashes.
  6. Date-times, such as 2022-02-03 19:03, or any other format you want.

• 🧬 Templates
  For complex kinds of data, you can use templates. A template is a list of data types that should be concatenated to create random data. Insert phone numbers, email addresses, URLs, IP addresses, or any custom data type you can think of. Of course, Randomness comes bundled with a whole array of predefined templates to help you out. If needed, you can reuse a template by including it in another template using a reference.

  

• 🗃️ Arrays
  Need a lot of data? Insert an entire array of any template you want. For example, an array of integers might look like [978, 881, 118, 286, 288]. You can customise the brackets, delimiter, and number of elements to your liking every time you insert an array, because no two arrays are the same.

  

• ⌨️ Shortcuts
  Instead of using up all your shortcuts, Randomness only uses the Alt + R (or ⌥R) shortcut by default. However, to streamline your workflow, you can assign shortcuts to any template under your IDE's Keymap settings.

  

• 💨 Fast insertion
  The insertion popup (shown when you press Alt + R (or ⌥R) by default) is searchable: Just type something in the popup and relevant templates will be filtered out. Or use the hotkeys that are assigned to the first 10 templates in the list: Press any digit to directly insert the corresponding template. Reorder templates in the settings menu to change which template uses which hotkey.

  

• 👀 Previews
  To help you decide what settings to choose, a preview of the template is shown while you're editing.

  

💻 Development

This section contains instructions in case you want to build the plugin from source or want to help with development. Please also check the contribution guidelines.

🔨 Build/run

$ gradlew runIde                       # Open a sandbox IntelliJ instance running the plugin
$ gradlew buildPlugin                  # Build an installable zip of the plugin
$ gradlew buildPlugin -Pbuild.hotswap  # Same as above, but allow hot-swapping the plugin during development
$ gradlew signPlugin                   # Sign built plugin

Signing the plugin requires specific environment variables to be set to refer to appropriate key files. See Plugin Signing for more information.

🧪 Quality assurance

$ gradlew test                    # Run tests (and collect coverage)
$ gradlew test --tests X          # Run tests in class X (package name optional)
$ gradlew test -Pkotest.tags="X"  # Run tests matching tag(s) X (also supports not (!), and (&), or (|))
$ gradlew koverHtmlReport         # Create HTML coverage report for previous test run
$ gradlew check                   # Run tests and static analysis
$ gradlew runPluginVerifier       # Check for compatibility issues

🏷️ Tagging and filtering tests

Kotest tests can be tagged to allow selectively running tests. The tags for Randomness are statically defined in Tags.

Tag an entire test class by adding tags(...) to the class definition, or tag an individual test context by writing context("foo").config(tags = setOf(...)) {. It is not possible to tag an individual test due to limitations in Kotest.

To run only one context in some test class X, prefix the context's name with f: and run with --tests X. The prefix f: filters out other contexts in that test class, and --tests X filters out other test classes. Alternatively, tag the desired context with the Focus tag and run with -Pkotest.tags="Focus" to filter by that tag.
