Some zip files do not list directories separately from files. For example, a zip might contain `dir/file.txt` without a corresponding entry for just `dir/`. This should be okay, so we just create the leading paths for the files we extract as necessary.
Also adds tests for the expected and dangerous path cases of `extract_zip`.
I believe that technically this function is part of the public API via `dioxus_cli::cli::cfg::parse_public_url`. However, I don't see any evidence that this function is actually used inside or outside this crate. The last use within the crate was removed in January 2022 (9bb10c65a3).
* fix(serve): provide a clear error with pathless proxy URLs
Without this, `dx serve` panics with this message:
```
Paths must start with a `/`. Use "/" for
root routes
```
That's not very clear. Instead, we can detect this situation and provide a better error message:
```
Error: 🚫 Serving project failed: Failed to establish proxy: Proxy backend URL must have a non-empty path, e.g. http://localhost:8080/api instead of http://localhost:8080
```
* docs(config): correct format for `web.proxy`
Previously an invalid `Dioxus.toml` file would yield this error when running e.g. `dx serve`:
```
Error: Failed to load `Dioxus.toml` because: Dioxus.toml parse failed
```
This doesn't give any indication why it failed to parse. This commit updates it to include why the parsing failed, e.g.:
```
Error: Failed to load Dioxus config because: Dioxus.toml missing field `name` for key `application` at line 38 column 1
```
I initially had it format the message to include `Dioxus.toml:38:1` to be clickable in some terminals, but the location specified didn't always seem particularly relevant to the actual problem so I left it as-is.
This also fixes what I believe would be an issue on case-sensitive file systems where if `dioxus.toml` existed it would try to read `Dioxus.toml`.
I'm still fairly new to Rust, so the `.as_path()` calls may not be the best way to deal with the fact that the borrow checker wouldn't let me re-use `crate_dir` and `dioxus_conf_file`. I'm open to suggestions!
