| # Configuring VS Code for ICU4C |
| |
| - Create a `.vscode` folder in icu4c/source |
| - Copy the `tasks.json`, `launch.json` and `c_cpp_properties.json` files into |
| the `.vscode` folder. |
| - To test only specific test targets, specify them under `args` in |
| `launch.json`. |
| - To adjust the parallelism when building, adjust the `args` in `tasks.json`. |
| - `-l20` tells VSCode to not launch jobs if the system load average is above |
| 20 (note that the [system load |
| average](https://en.wikipedia.org/wiki/Load_(computing)) is *not* a CPU |
| usage percentage). |
| - `-j24` limits the number of jobs launched in parallel to 24. The system |
| load average takes a while to respond, reducing this number helps the |
| initial bad system performance when a new build is launched. |
| |
| NOTE: |
| Run the |
| [`./runConfigureICU` command](https://unicode-org.github.io/icu/userguide/icufaq) |
| before building `icu4c` from VSCode. |
