At my current place of work, we use detailed branch names including issue number and a description of the feature. Run this command to clone the git-completion bash. It will be called,.

Now open. And paste this at the bottom. Avoid this by putting the current branch name in front of you at all times. Add the branch name to our command line prompt. And paste the following.

When you open a new terminal, the current branch name will be displayed. Long cryptic commands are the enemy of efficiency. Why not write our own shortcuts or aliases. This allows you to set a custom command in order to run a longer command. Use the following syntax. This allows me to open jupyter notebooks with a high data rate limit, with jup instead of that insanely long command. As Larry Wall, creator of Perl, said:. The 3 chief virtues of a programmer are: laziness, impatience and hubris. Copy and paste it into a file called CommandLine. The picocli-codegen module includes an annotation processor that can build a model from the picocli annotations at compile time rather than at runtime.

Enabling this annotation processor in your project is optional, but strongly recommended. Compile time error checking. The annotation processor shows errors for invalid annotations and attributes immediately when you compile, instead of during testing at runtime, resulting in shorter feedback cycles. GraalVM native images. This includes configuration files for reflection , resources and dynamic proxies.

By embedding these configuration files, your jar is instantly Graal-enabled. In most cases no further configuration is needed when generating a native image. The examples below show how to do this for Maven and Gradle.

Kotlin projects should add the kotlin-kapt plugin to enable the Kotlin Annotation processing tool kapt , then replace annotationProcessor with kapt :. There are many ways to run picocli-based applications, depending on whether we included picocli as source, created a jar for our application or not, and whether we created a shaded jar also known as uber-jar containing all dependencies. For example:. Now, assuming we created a jar named checksum. You may want to package your application in such a way that end users can invoke it with a short command like this:.

See the Packaging Your Application section for ideas on how to accomplish this. Command line arguments can be separated into options and positional parameters. Options have a name, positional parameters are usually the values that follow the options, but they may be mixed. An option must have one or more names. Picocli lets you use any option name you want. Option names are case-sensitive by default, but this is customizable.

The below example shows options with one or more names, options that take an option parameter, and a help option. Picocli 3. When running on Java 6 or higher, picocli will use the Console. From picocli 4. The example below demonstrates how an interactive option can be used to specify a password. From picocli 3. When running on Java 6 or higher, the user input is not echoed to the console. After the user enters a password value and presses enter, the call method is invoked, which prints something like the following:. Interactive options by default cause the application to wait for input on stdin.

For commands that need to be run interactively as well as in batch mode, it is useful if the option can optionally consume an argument from the command line. The default arity for interactive options is zero, meaning that the option takes no parameters. See Optional Values. With the following input, the password field will be initialized to "" without prompting the user for input:.

However, if the password is not specified, the user will be prompted to enter a value. In the following example, the password option has no parameter, so the user will be prompted to type in a value on the console:.

Note that specifying a password in plain text on the command line or in scripts is not secure. There are alternatives that are more secure. One idea is to add a separate different option that could be named --password:file that takes a File or Path parameter, where the application reads the password from the specified file. Such a command can be executed both interactively and in batch mode. The picocli-examples module has an example, coded both in Java and Kotlin. Picocli supports POSIX clustered short options : one or more single-character options without option-arguments, followed by at most one option with an option-argument, can be grouped behind one '-' delimiter.

The following command line arguments are all equivalent and parsing them will give the same result:. The value of x is false by default, and is set to true the opposite of the default if the -x option is specified on the command line. If the -x option is specified multiple times on the command line, the value of x remains true.

Prior to picocli 4. This can still be configured if required. This is enough in most cases, but picocli offers alternatives for applications that need to get the value from something other than the default value.

When the option is specified on the command line, the annotated field or method is assigned a value, as follows:. If the parser is configured to toggle boolean options , the opposite of the current value is assigned.

This was the default prior to picocli 4. If a fallback value is defined, the fallback value is assigned. If the option is defined with a non-zero arity , and an option parameter was specified on the command line, this option parameter value is assigned. When an option is negatable, picocli will recognize negative aliases of the option on the command line.

Short option names are not given a negative alias by default. This is customizable.

If the negated form of the option is found, for example --no-verbose , the value is set to the provided default. Otherwise, with a regular call, for example --verbose , it is set to the opposite of the default. When end users specify --no-backup on the command line, the value is set to false. The negated form of this option is --backup , and if that is specified, the default value is applied. Any command line arguments that are not subcommands or options or option parameters are interpreted as positional parameters.

Positional parameters generally follow the options but from picocli 2. Use the zero-based index attribute to specify exactly which parameters to capture. Array or collection fields can capture multiple values.

Range values can be open-ended. See Strongly Typed Everything for which types are supported out of the box and how to add custom types. It is possible to omit the index attribute. This means different things for single-value and for multi-value positional parameters.
