Doc: Cached files aren't in DENO_DIR

[LarryBattle]

Deno Version

1.0.2

OS

Linux (Ubuntu 18+)

Problem

I installed Deno today to play around with it and after running some example code, Deno told me it compiled my typescript file but didn't state where it stored it.

$ deno run --reload example.ts 
Compile file:///home/me/deno_test/example.ts
hello world

The documentation says the default deno directory is at $HOME/.deno but only the deno binary was there.

$ find $HOME/.deno -type f
/home/me/.deno/bin/deno

`DENO_DIR` defaults to `$HOME/.deno` but can be set to any path to control where
generated and cached source code is written and read to.

• setup_your_environment.md

The code actually says it uses the OS cache directory.

// We use the OS cache dir because all files deno writes are cache files
// Once that changes we need to start using different roots if DENO_DIR
// is not set, and keep a single one if it is.
let default = dirs::cache_dir()

• deno_dir.rs

After more digging I finally discovered the deno info command to reveal the true location of the cached content.

Expected

$ deno info
DENO_DIR location: "/home/me/.deno"
Remote modules cache: "/home/me/.deno/deps"
TypeScript compiler cache: "/home/me/.deno/gen"

Actual

$ deno info
DENO_DIR location: "/home/me/.cache/deno"
Remote modules cache: "/home/me/.cache/deno/deps"
TypeScript compiler cache: "/home/me/.cache/deno/gen"

Possible Solutions:

To save Deno newbies time in finding the location for the cached content, could the setup_your_environment.md documentation be updated to mention that the deno info command will reveal the true location of your cached files?

Or maybe include a verbose option in the deno run command that prints out the location of the cached files. verbose logging reveals the location deno run --log-level debug --reload example.ts

As you mentioned the information in the documentation is out of date. DENO_DIR defaults to the cache directory, not ~/.deno.

Doc improvements are very welcome!
