Things to do:

• [x] implement thread-local engine setting for default_engine
• [ ] make sure everything are defined globally (a bit difficult, e.g. https://tex.stackexchange.com/q/357869/250119)
• [ ] split newenvironment_verb into helper functions
• [ ] split f1 into helper functions to allow customization (e.g. ⟨a:08b⟩?)
• [ ] split simple module into parts. Plan:
  • [ ] simple_helper: functions that does not need to be used directly at document level but may be useful to define new functions
  • [ ] simple_extra: those that can be built with simple_helper and simple_extra (to recommend user to read source code)
  • [ ] simple: the rest
• [ ] extension modules (e.g. for SageMath)
• [x] some API to manipulate catcodes counts dimens etc.
• [ ] Make newenvironment_verb not strip spaces at the end of the line
• [ ] Define an environment that gobbles the body in str-type tokenization
• [x] Get arguments delimited
• [ ] Get pair-delimited argument (d-type and D-type argument in xparse)
• [x] Function to write to log file (why?)
• [ ] Function to parse log file for things such as \showoutput (very hacky...)
• [ ] Expandable functions for Lua
• [ ] pysub environments, evalz() in Python, etc.
• [ ] preprocess pycode to allow using inside command argument (with a few caveats, but still good)
• [ ] restore select.select for unnamed pipe or threading to cancel the pipe on timeout
• [ ] refactor serialization to allow passing more data in a structured way
• [x] Catch error from ChildProcessEngine
• [ ] Give reasonable error on overleaf when files are missing...

Original architecture was a bit of a mess, admittedly.

• [x] move _handlers to engine-specific (update: turns out to be a bit difficult because add_handler is global to all engines)
• [ ] move action_done to private
• [ ] move a bunch of other things to private
