Name Casing#

Use Humanizer with CommandDotNet to convert the case of command and arguments to PascalCase, camelCase, lowercase or kebab-case.

TLDR, How to enable#

dotnet add package CommandDotNet.NameCasing

Install-Package CommandDotNet.NameCasing

Enable the feature with appRunner.NameCasing(...)

Case options#

public class App
{
    public void MigrateUser([Option]bool dryRun){...}
}

With Case.DontChange, the command is executed as MigrateUser --dryRun

With Case.PascalCase, the command is executed as MigrateUser --DryRun

With Case.CamelCase, the command is executed as migrateUser --dryRun

With Case.KebabCase, the command is executed as migrate-user --dry-run

With Case.LowerCase, the command is executed as migrateuser --dryrun

Overridden names#

By default, the case is only applied where the name has not been overridden in an attribute.

public class App
{
    [Command(Name="migrateUser")]
    public void MigrateUser([Option(LongName="DryRun")]bool dryRun){...}
}

the command is executed as MigrateUser --DryRun.

Use the applyToNameOverrides option to apply case conversion to migrateUser and DryRun.

Caveats

Humanizer behavior

  • Lowercase cannot be converted to another case... except, the first letter will be capitalized for Pascal. Humanizer doesn't know where the second word starts.
  • Kebabcase cannot be converted to camelcase or lowercase. No idea why.
  • Camel and Pascal can be converted to any other case

Custom Name Transforamtions#

use appRunner.Configure(c => c.NameTransformation = ...) to apply custom name transformations.

Example: Humanizer middleare

This example will lowercase all names

appRunner.Configure.NameTransformation = 
    (attributes, memberName, nameOverride, commandNodeType) 
        => (nameOverride ?? memberName).ToLower()`
