wwbrannon / ado Goto Github PK

The way it stores ado command history is a godawful hack, probably also a race condition, and is Unix-specific. Is there a better way?

Need a function that converts varlists to R formulas, for use in modeling functions

Symbols should be coerced to character in varlist, expression_list and expression where this makes sense.

Need support for so-called "c-class values": the system parameters accessible under c(). They need to be usable

• in expressions, unquoted
• in macros

We'll also need to implement the creturn command to list them.

The dataset variables need to be visible by their column names, and the modified dataset needs to be assigned back to rstata_env afterward.

Use within()?

This needs to describe - really, focus on - differences from Stata.

Update various non-vignette docs and CRAN peccadilloes:

• the package NULL
• R functions
• README.Rmd
• DESCRIPTION and in particular its long description
• cran-comments
• NEWS.md
• NAMESPACE

Nothing fancy, just needs to print a usage message

Variable names should be able to be abbreviated to the shortest unambiguous substring. Other abbreviation syntax (ranges etc) won't be supported.

Stata's two data types for string and numeric map fairly cleanly onto R's character and numeric. We need:

• the op_* functions for the factor and interaction operators
• relational operators (%==%, %>%, %<%, %>=%, %<=%) that implement a bivalent logic
• logical operators (%&%, %|%, %!%) that do the same
• confirm that base R's arithmetic operators work as-is without being wrapped
• subsetting (expressions like x[1] are legal in Stata) - does it work?
• assignment - does it work?
• type constructor operators - does the way this is set up now work?

There needs to be a way to print a backtrace for an R error / condition thrown at any point in executing a Stata command. It should be one of the OR-able debugging flags.

In particular, clean up the NAMESPACE

Commands need to be able to have return codes, and the _rc variable has to be set as the last command's return value

Memory leaks: three entry points to check, do_parse, parse_accept and do_parse_with_callbacks.

A mechanism for the user to persistently register an R function obeying the calling convention as a Stata command.

This way, we don't need much programming support, because R is the extension language.

Makevars and the parser's Makefile have to be generated by a configure script, not be hardcoded
