HN comment orderJust showed this to a math PhD grad student. Her eyes immediately lit up. She instantly determined that who ever made this, is in fact a genius. Great idea and great implementation. I have seen so much LaTeX frustration. This will definitely ease a lot of pain.
Related (but not identical), Facebook research just released an open source pdf -> markdown reader (that does a good job w/ equations in latex). https://facebookresearch.github.io/nougat/
Excellent tool! Used it heavily while writing my lecture summaries during my studies. Also, interesting to know: the backend was re-written in Haskell at one time; it gets mentioned in Daniel's thesis [0] http://danielkirs.ch/thesis.pdf
More than symbol names, I can never remember details about package options. To set uniform margins with the geometry package, is the keyword "margin" or "margins"? If I want to scale tgschola, is the keyword "scale" or "scaled"? Why don't package writers anticipate this? Similarly, depending on the font, the command to get an upright lowercase alpha is either \upalpha, \alphaup, \otheralpha, or something else. Why?
