[Roadmap] v0.8

[yuanming-hu]

This roadmap is deprecated. Please see #2398 instead :-)

• Migrate documentation to the new website (coordinator: @rexwangcc )
• Enforce code copyright info
  • Implement a script to add and check copyright info (Copyright declaration format issue #1024)
  • Set up a GitHub workflow to automatically check copyright info existence for every PR
  • Use @taichi-gardener to create a PR and add copyright info to all files
• Automatic release ([Workflow] Automatic version releases #1674, lead: @rexwangcc)
• Platform-independent wheel ([PyPI] [Blender] Make a platform independent wheel package by download-on-fly? #1987, lead: @archibate)
• Update issue templates (We need a refactor template)
• Shrink the misc folder
  • Completely remove that folder may not be possible since we do need a temporary folder to store files that do not belong everywhere else
• Set up pylint
  • A good start is [cli] Setup pylint: run 'ti lint' to obtain linting results #1846 (nicely done by @archibate)
  • We may need to think about how to continuously enforce Python linting using GitHub workflows
• Remove get_current_program ([refactor] [ir] IR system refactorings #988)
• ti format command should not need to import taichi
  • Otherwise, the format server will fail frequently, since it never compiles taichi_core when triggered and there is a mismatch between Python scripts and taichi_core.
• Non-POT internal nodes should no longer be allowed
• Update README.md (lead: @yuanming-hu)
  • Update large-scale examples and contributors
• Create a fresh new Context for args+earg+rets per-launch ([Refactor] Create a fresh new Context for args+earg+rets per-launch #1739, lead: @k-ye)
• Improve namespaces
  • Do we really need taichi::lang?
  • It may also make sense to replace taichi::lang with taichi::ir, taichi::backend etc.
  • Remove macros TLANG_NAMESPACE_BEGIN/TI_NAMESPACE_BEGIN?
• Refactor gather_statements (lead: @k-ye)
  • It seems what we really need is a "MapReduce" on the IR. gather_statements is often abused to achieve something else
• Support pointer on Metal (SNodeType=pointer not supported on Metal #1740, lead: @k-ye)
• Merge AppVeyor and Travis CI tasks so that we pay fewer dollars
• Vulkan backend

To lead the implementation of an item, please open up an issue, briefly describe the implementation plan, and wait for an approving response from one of the TSC members.

The roadmap lists our top-priorities and will be dynamically adjusted. We do encourage contributors to propose other items that they are interested in :-)
