4.0.0 Roadmap

[mattbasta]

Please update this issue with more.

Must-haves:

• Delete the html_* plugins for good, because they're scary
• Delete the count_* plugins, because they're mostly unused
• Delete the strip_tags plugin, since it's most likely not safe
• Delete all plugins banned in strict mode
• Delete the following plugins, because they violate web best practices:
  • capitalize: Use text-transform in CSS instead.
  • truncate: Use overflow and text-overflow in CSS instead.
  • date_format: Does not support proper localization, out of scope of Brainy.
• Remove the make_timestamp and escape_special_chars shared plugins, as they're only depended on by the plugins being removed above.
• Remove $smarty->template, which is banned in strict mode.
• Remove syntax features banned by strict mode.
• Remove support for built-in functions with side effects that are banned in strict mode: reset(), current(), etc.
• Remove SmartyBC.
• Remove the inline param from {include}.
• {* set stricter *} that requires all included templates to be strict

Nice-to-haves:

• AST-based parser and compiler
• Make it impossible to {include} or fetch a file outside of one of the recognized template directories.
• Mode that reports which assigned variables were not accessed
  • API should be similar to fetchedTemplate() overridable method
  • Should be enabled with a static flag
  • May be possible to implement by making the scope array inside TemplateData be an object implementing PHP's ArrayAccess interface with zero overhead while mode is off (no new code branches)
• Make buildFilepath not be insane.

Stretch:

• 80% code coverage
• ~100% code coverage for bundled plugins
• Cut compilation times by 25%
• Reduce IO-related PHP calls (filemtime, getcwd, etc.) by 25%
