QUESTION
I am in the process of developing an R package with external source code that takes a long time to compile. While compilation time isn't a big problem for a one-off installation, I have to routinely reinstall the package to test new additions. Is it possible to prevent re-compiling the source code if there haven't been any changes to it?
I don't necessarily need this to be automated, but I can't figure out a manual solution either. As my source code is in Rust, the following serves as the most representative example I have (note that it requires Rust cargo to be installed):

Answered 2020-May-11 at 14:39Based on the comments by r2evans, the final answer seems to be that this isn't what devtools::install
is for.
As per the devtools
documentation, there are three main tools for "frequent development tasks":
load_all
document
test
Of these load_all
"simulates installing and reloading your package, loading R code in R/, compiled shared objects in src/ and data files in data/". By default, load_all()
will not recompile source code in src/ (unless the recompile
flag is set to true).
So the answer is to use load_all
as opposed to install
during package development and manually control when to compile the source code using something like devtools::compile_dll
.
