Hi,
Would it be possible to add the capability for functions to register how
they would like to complete themselves.
Currently, there is the .addFunctionInfo, but it allows only functions
to register a static list of potential completions, I was thinking of a
way to register not a fixed list of possible completions, but a
__function__ that would calculate completions dynamically.
This could be useful for the "new" function in R, if associated with
something that can retrieve the current list of S4 classes (not sure
this exists).
Another example of where this could be used would be the .jnew function
from rJava, where the first argument is a java class, associated with
something that can complete java class names.
Not sure, but another example may be a class dependent completion for
generic functions depending on first argument. Like print(df,... ) where
df a data.frame to complete, digits = NULL, quote = FALSE, right = TRUE,
row.names = TRUE instead of only (x,...).
Vitalie.
