I would like to share a bash script I made for when you want to simply run a rust script once and delete it. Instead of having compile the script with rustc, running the binary and then deleting the binary, you can achive all of this with this bash script below.

The first argument will be the rust script file name. The .rs file extension is optional. The rest of the arguments are passed into the executed binary.

Simply name the bash script to something like rust-run.sh.

#!/bin/bash

#Get file path from first parameter
path=$(dirname "$1")

#Get file name from first parameter
fileName=$(basename "$1")
fileName="${fileName%'.rs'}"

#Compile executable and save it in the same directory as the rust script
rustc "${path}/${fileName}.rs" -o "${path}/${fileName}"

#If rustc commands retuned any errors, unable to compile the rust script
if [ $? -ne 0 ]; then
    return
fi

#Execute compilled executable and pass the rest of the parameters into the executable
"${path}/${fileName}" ${*:2}

#Delete compillled executable
rm "${path}/${fileName}"

If someone wants to rewrite this in rust or add these features into the rustc, feel free to do so.

Should I create functions/methods for packages/libraries that allow optional parameters to accept null?

In this example below, I set the 3rd and 4th parameter as null which will act as the default value.

myLibrary.myFunction(1, 7, null, null, true);

Or is this not a good way to go about creating functions for a package and therefore should not accept null as a parameter value.

myLibrary.myFunction(1, 7, false, 4, true);

Just started learning Rust today and got Rust installed, got the hello world example compiled and running. I installed rust-analyzer and CodeLLDB extensions in VSCode. Enable the debug.allowBreakpointsEverywhere settings to VSCode to be true. Setup a debug configuration in VSCode.

However I keep getting errors from rust-analyzer when I run the debugger...

2024-10-06T22:16:04.808655Z ERROR FetchWorkspaceError: rust-analyzer failed to load workspace: Failed to load the project at /home/john/Documents/Snippets/Rust/Cargo.toml: Failed to read Cargo metadata from Cargo.toml file /home/john/Documents/Snippets/Rust/Cargo.toml, Some(Version { major: 1, minor: 81, patch: 0 }): Failed to run `cd "/home/john/Documents/Snippets/Rust" && RUSTUP_TOOLCHAIN="/home/john/.rustup/toolchains/stable-x86_64-unknown-linux-gnu" "/home/john/.cargo/bin/cargo" "metadata" "--format-version" "1" "--manifest-path" "/home/john/Documents/Snippets/Rust/Cargo.toml" "--filter-platform" "x86_64-unknown-linux-gnu"`: `cargo metadata` exited with an error: error: failed to parse manifest at `/home/john/Documents/Snippets/Rust/Cargo.toml`

Caused by:
  no targets specified in the manifest
  either src/lib.rs, src/main.rs, a [lib] section, or [[bin]] section must be present

I not sure how to fix this.

I would like to get the VSCode debugger to work for launch debugging, attach debugging and launch and attach debugging for rust running inside a docker container. This will be a good setup for getting started I believe.

This is my VSCode debugger configuration...

			"program": "${workspaceFolder}/hello-world",
			"args": [],
			"cwd": "${workspaceFolder}"
		}
	]
}

Any help and advice will be most appreciated.

I hope this project gets more contributors to help make it as good or better than Newpipe. Written in Dart using Flutter can allow it to be compiled for Android, iOS and desktop

Upvote the issue on Github if you want to see this feature added into VSCode.

I was able to setup a debugger using a launch mode using Visual Studio Code with the Bash Debug extension. Is it possible to setup the debugger in VSCode to be able to debug a bash script using a attach debug mode?

For debugging scripts on the host machine and scripts inside a docker container?

Here is how you can add a simple action to open a folder in VSCodium within Nemo file manager.

1. Create a new file in ~/.local/share/nemo/actions/ and name the file vscodium.nemo_action
2. Open the file in a text editor
3. Copy the code below into the file

[Nemo Action]
Name=Open in VSCodium
Comment=Open VSCodium in the selected folder
Exec=codium %F
Icon-Name=vscodium
Selection=Any
Extensions=dir;

4. Save the changes made to the file
5. Now when you right click inside a folder in Nemo, it will show an option "Open in VSCodium" and when you click this option, it will launch VSCodium using the currently directory as the workspace.

This can be modified to work with Visual Studio Code (Which is closed source unlike VSCodium) by editing codium %F to code %F

Do we need live reload feature in bunders? Couldn't we just use this extension for Visual Studio Code or simular features and extensions in other IDEs which will execute a custom command of your choice when you save a file with a certain file extension in your IDE?

https://marketplace.visualstudio.com/items?itemName=emeraldwalk.RunOnSave

This extensions allows you to customize the commands to execute in saving a file in your global VSCode settings and in the VSCode workspace settings .vscode/settings.json, allowing others to use the same configuration in group projects.

Lightning CSS does not have a live reload feature and the live reload feature in Rollup cannot handle watching many files, however using this extension in VSCode, will not watch files but run the npm run dev:css or npm run dev:js command when saving a css or js file without watching for files to change.

One downside I see with this is when working on a project with others who are using different IDEs that do not support this feature. Besides that, is there any downsides to this approach?

Is there an easy way to enable a inactivity timer when using a TTY like in Ubuntu Server for when there has been no inactivity for X seconds, it will execute vlock and lock the TTY.
