tauri | Build smaller , faster , and more secure desktop applications

Turns out, the culprit was defaultPath field.

You have to provide a valid path there (or not use it at all), otherwise it will fail silently.

One way to do this is as follows

The issue comes from TextEditingController while it contains initial value 0. You can simply remove this.

Are all these Arcs, Mutexes and clones necessary?

Probably not, you seem to be way over-cloning -- and rewrapping concurrent structure, but you'll have to look at the specific APIs

e.g. assuming broascast::channel is Tokio's it's designed for concurrent usage (that's kinda the point) so senders are designed to be clonable (for multiple producers) and you can create as many receivers as you need from the senders.

There's no need to wrap in an Arc, and there's especially no need whatsoever to protect them behind locks, they're designed to work as-is.

Furthermore, in this case it's even less necessary because you have just one sender task and one receiver tasks, neither is shared. Nor do you need to clone them when you use them. So e.g.

The register signature won't allow yourself to change "hotkey" even. First by "&mut self" constraint and second by the callback that's should be 'static

To answer your question, it's not possible yet to cross-compile a Tauri application. (Example, building a Windows artifact from a Linux machine)

The best would be to use Github Actions to build it for you.

Tauri have a pre-built action, ready to use.

You can find some examples here;

• https://github.com/cloudflare/workerskv.gui/blob/master/.github/workflows/release.yml#L59
• https://github.com/Levminer/authme-lite/blob/dev/.github/workflows/release-artifacts.yml#L35

If I understand correctly, you are trying to capture only one # symbol at the beginning of each line.

The regular expression that helps you solve the issue is: r"(?:^|\s)(?:[#]\ )(.*\n+##\ ([^#]*\n)+)". The brackets isolate the capturing or non capturing groups. The first group (?:^|\s) is a non capturing group, because it starts with a question mark. Here you want that your matched string starts with the beginning of a line or a whitespace, then in the second group ([#]\ ), [#] will match exactly one # character. \ matches the space between the hash and the h1 tag text content. finally you want to match any possible character until the end of the line so you use the special characther ., which identifies any character, followed by + that will match any repetition of the previous matched character.

This is probably the code snippet you are looking for, I tested it with the same sample test you used.

I've been able to run a Spark server on Android. Here is my build.gradle.
