new feature: ConsoleHelper

[weierophinney]

Provides the following:

• Console output using STDOUT for meaningful, expected output
• Console output using STDERR for error messages
• Ensures any line breaks are converted to PHP_EOL
• Optionally provides console color escape sequences to provide context, which means:
  • Detecting whether or not the console supports colors in the first place
  • Providing appropriate escape sequences to produce color

This feature is being developed to support some of the console tooling we've been creating, including:

• zf-development-mode
• zf-composer-autoloading
• new zend-servicemanager factory/configuration generation tooling

Essentially, tools that have zero or small numbers of arguments that can be easily parsed manually, but for which we want to provide color output.

Ping @GeeH !

Looks good, but I wonder why this is not added to Zend\Console.

[weierophinney]

@RalfEggert I discussed that with @GeeH , and we had three possibilities open to us.

Action	Pros	Cons
Add to zend-console	Same domain, many utilities already present.	Adds zend-stdlib as an additional requirement; makes the code largely redundant.
Create new repo	SRP, small footprint	Another component to maintain.
Add to zend-stdlib	Most repos already require it; no additional dependencies; small footprint.	Appearance of duplication.

Interestingly, zend-servicemanager, which is where we originally started developing this, has no requirements other than container-interop, which meant if we created the functionality elsewhere, it automatically means an additional requirement for the component. To keep requirements minimal, we felt the second and third options made most sense, and since this package already has infrastructure, felt the maintenance overhead would be better suited here.

@weierophinney Thanks for clarification!

[GeeH]

All good.
