+# Nomadic Weather CLI
+
+Prototype for playing with [Open-Meteo](https://open-meteo.com).
+
+Locations need modified manually since it's still just a prototype.
+
+## prototype.js
+
+Got a little carried away and made it pretty formal.
+Still a prototype though since the locations are hardcoded.
+Would be made more complete by accepting a list of values, an env file,
+or basically just any way of handling the locations as user input.
+
+## install.sh
+
+Allows the script to be installed either in ~/bin/ or /usr/local/bin/.
+Also handles removal if it is no longer wanted.
+Currently does not remove from /usr/local/src/.

+This is a Kotlin Multiplatform project targeting Android, Desktop (JVM), built with the [Kotlin Toolchain](https://kotlin-toolchain.org/dev/).
+
+- [/androidApp](./androidApp) contains the Android application.
+- [/desktopApp](./desktopApp) contains the desktop (JVM) application.
+- [/shared](./shared) holds the code shared across your applications — Compose UI, business logic, and platform-specific implementations. [src](./shared/src) is for common code; the sibling `src@<platform>` folders (for example `src@android`) hold code compiled only for the platform named in the folder.
+
+The `kotlin` (macOS/Linux) and `kotlin.bat` (Windows) scripts in the project root are self-bootstrapping wrappers for the Kotlin Toolchain: they download the pinned toolchain version on first use, so no separate installation is required. Build the whole project with `./kotlin build`.
+
+### Running
+
+Use the run configurations provided by the run widget in your IDE's toolbar. You can also run each module from the command line:
+
+- Android app: `./kotlin run -m androidApp`
+- Desktop app: `./kotlin run -m desktopApp`
+
+### Testing
+
+Run the project's tests with `./kotlin test`, or `./kotlin test -m <module>` for a single module.

+@rem This multiline string is actually passed as a single line to powershell, meaning #-comments are not possible.
+@rem So here are a few comments about the code below:
+@rem  - we need to support both .zip and .tar.gz archives (for the Kotlin Toolchain distribution and the JRE)
+@rem  - tar should be present in all Windows machines since 2018 (and usable from both cmd and powershell)
+@rem  - tar requires the destination dir to exist
+@rem  - native commands like tar don't raise PowerShell errors on failure, so we have to check $LASTEXITCODE.
+@rem    The extraction must never be left half-done with the .flag file in place, because the .flag file marks the
+@rem    target dir as complete, and subsequent runs would then skip the extraction and use the broken directory.
+@rem  - We use (New-Object Net.WebClient).DownloadFile instead of Invoke-WebRequest for performance. See the issue
+@rem    https://github.com/PowerShell/PowerShell/issues/16914, which is still not fixed in Windows PowerShell 5.1
+@rem  - DownloadFile requires the directories in the destination file's path to exist
