pidcat

During Android application development, we often want to display only the current log information of our own application. Unfortunately, since the process ID changes every time it is deployed to the phone, isn't it trying to find a log filtering tool that can solve this problem.

pidcat is all about filtering the application logs by matching the application packages. Then you can enjoy a more convenient development process.

here is an example.

pidcat toor

Install terminal by sourcecode

First install the rust environment

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Download source

git clone https://github.com/borneygit/pidcat.git

cd pidcat

Then use cargo to install pidcat

cargo install --path .

Install terminal by brew

brew tap borneygit/brew

brew install borneygit/brew/pidcat

How to use terminal

Use by crate

add dep for Cargo.toml

[dependencies]
pidcat="0.2.0"

You can use the following code to capture the adb logcat logs and process them twice according to your needs

use futures::StreamExt;
use pidcat::LogStream;
use pidcat::source::*;

#[tokio::main]
async fn main() {
    let source = ADBSource::new(None);

    let mut logs: LogStream = source.source().await;

    while let Some(r) = logs.next().await {
        if let Ok(log) = r {
            println!("{}", log);
        }
    }
}
