Hi @BlowaterNostr,
This appears to be about the basic-cli path example.

I'm not sure if you want to build the platform from source or not, if not use this:

app [main] { pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.17.0/lZFLstMUCUvd5bjnnpYromZJXkQUrdhbva4xdBInicE.tar.br" }

import pf.Stdout
import pf.Path

main = run |> Task.onErr \err -> crash "ERROR: $(Inspect.toStr err)"

run =
    path = Path.fromStr "path.roc"
    a = Path.isFile! path
    b = Path.isDir! path
    c = Path.isSymLink! path
    d = Path.type! path

    Stdout.line "isFile: $(Inspect.toStr a) isDir: $(Inspect.toStr b) isSymLink: $(Inspect.toStr c) type: $(Inspect.toStr d)"

if you do want to build basic-cli from source:

# In the basic-cli folder:
git checkout 0.17.0
./jump-start.sh
roc build.roc --linker=legacy

If I made an incorrect assumption, seeing your full examples/path.roc and any commands you ran before this one would be helpful.

I'll add a nice comment that links to the build instructions in each example.

I've made some improvements to the basic-cli examples:
roc-lang/basic-cli@f2825da
roc-lang/basic-cli#300

Feel free to provide additional suggestions for improvements.

@Anton-4 the code you pasted works but I get a new error:

app [main!] {
    pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.17.0/lZFLstMUCUvd5bjnnpYromZJXkQUrdhbva4xdBInicE.tar.br",

}

import pf.Http
import pf.Stdout
import json.Json

# HTTP GET request with easy decoding to json
main! = \_args ->

    # Easy decoding/deserialization of { "foo": "something" } into a Roc var
    { foo } = try Http.get! "http://localhost:8000" Json.utf8
    # If you want to see an example of the server side, see basic-cli/ci/rust_http_server/src/main.rs

    Stdout.line! "The json I received was: { foo: \"$(foo)\" }"

got

✗ roc run http-get-json.roc
An internal compiler expectation was broken.
This is definitely a compiler bug.
Please file an issue here: <https://github.com/roc-lang/roc/issues/new/choose>

@BlowaterNostr -- you've posted an example using the older release of basic-cli. The new (still pre-release) is required if you want to use purity inference.

This works for me.... if I have a server running locally

app [main!] {
    pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.18.0/0APbwVN1_p1mJ96tXjaoiUCr8NBGamr8G8Ac_DrXR-o.tar.br",
    json: "https://github.com/lukewilliamboswell/roc-json/releases/download/0.11.0/z45Wzc-J39TLNweQUoLw3IGZtkQiEN3lTBv3BXErRjQ.tar.br",
}

import pf.Http
import pf.Stdout
import json.Json

# HTTP GET request with easy decoding to json
main! = \_args ->

    # Easy decoding/deserialization of { "foo": "something" } into a Roc var
    { foo } = try Http.get! "http://localhost:8000" Json.utf8
    # If you want to see an example of the server side, see basic-cli/ci/rust_http_server/src/main.rs

    Stdout.line! "The json I received was: { foo: \"$(foo)\" }"
