parser
was built in core R from version 3.0.0 and it has really great features that I use e.g. in my sandboxR package, which also has to check bunch of stuff about user provided R code. Quick demo:
> getParseData(parse(text = 'library(RColorBrewer)'))
line1 col1 line2 col2 id parent token terminal text
9 1 1 1 21 9 0 expr FALSE
1 1 1 1 7 1 3 SYMBOL_FUNCTION_CALL TRUE library
3 1 1 1 7 3 9 expr FALSE
2 1 8 1 8 2 9 '(' TRUE (
4 1 9 1 20 4 6 SYMBOL TRUE RColorBrewer
6 1 9 1 20 6 9 expr FALSE
5 1 21 1 21 5 9 ')' TRUE )
from lintr.
Yep I am using the built in parser functions extensively in lintr, this
issue was just a place for me to keep links to pre-existing linting tools
