如何在R CLI中使用依赖RStudio及rstudioapi的Thing包？

Alright, let's tackle this without having to rewrite the entire Thing package—no need to reinvent the wheel here. The core issue is that the package relies on rstudioapi::askForPassword() which only works inside RStudio, but we need to run it in the R CLI. Here are a few practical workarounds:

1. Swap out askForPassword for a CLI-friendly alternative #

We can redefine the rstudioapi::askForPassword function before calling setup_thing() so it uses a password input method that works in the terminal. The getPass package is perfect for this because it hides your password as you type (way safer than plain readline()).

Here's how to do it:

# Install getPass if you haven't already
if (!requireNamespace("getPass", quietly = TRUE)) {
  install.packages("getPass")
}

# Load rstudioapi first
library(rstudioapi)

# Overwrite the askForPassword function with a CLI-compatible version
askForPassword <- function(prompt) {
  getPass::getPass(prompt = prompt)
}

# Now run setup_thing() as usual
setup_thing()

When setup_thing() calls rstudioapi::askForPassword() internally, it'll use our custom version instead—no more RStudio check failure.

2. Use an environment variable to pass the password #

If your workflow allows it, you can store your password in an environment variable and have the package read that instead of prompting you. This is especially handy for automated scripts.

# First, set the environment variable (do this outside R for security, like in your shell: export THING_PW="your_password")
# Or temporarily set it in R (never hardcode passwords in scripts!)
Sys.setenv(THING_PW = "your_password")

# Overwrite askForPassword to pull from the environment variable
library(rstudioapi)
askForPassword <- function(prompt) {
  Sys.getenv("THING_PW")
}

setup_thing()

Heads up: Never hardcode your password in a script. Set the environment variable in your shell profile or use a secure secrets manager if collaborating with a team.

3. Fake the RStudio environment (quick hack) #

Some parts of rstudioapi check for specific environment variables to confirm it's running in RStudio. We can set these temporarily to trick the package into thinking it's in RStudio. Combine this with the first method for best results:

# Set RStudio-specific environment variables
Sys.setenv(RSTUDIO = "1")
Sys.setenv(RSTUDIO_TERM = "1")

# Load rstudioapi and overwrite the password prompt function like before
library(rstudioapi)
askForPassword <- function(prompt) {
  getPass::getPass(prompt = prompt)
}

setup_thing()

This might not work for all rstudioapi functions, but for just the password prompt scenario, it should get the job done.
