VSCode - jniedzie/SVJanalysis_wiki GitHub Wiki

We recommend that you use VSCode. You can download VSCode here: https://code.visualstudio.com/download
The steps below explain how to connect to the T3 with VSCode.

Add these lines to your ~/.ssh/config file on your laptop, replacing <user> by your T3 username.

Host t3ui01.psi.ch
        HostName t3ui01.psi.ch
        User <user>

Host t3ui02.psi.ch
        HostName t3ui02.psi.ch
        User <user>

Host t3ui03.psi.ch
        HostName t3ui03.psi.ch
        User <user>

Connect to the T3 in a terminal, go to where you installed the FW:

cd ~/SVJanalysis

Put these lines in a file called svj_analysis.code-workspace:

{
    "folders": [
        {
            "path": "."
        }
    ],
    "settings": {
        "python.defaultInterpreterPath": "/work/fleble/anaconda3/envs/svj14/bin/python",
        "python.analysis.extraPaths": [
            ".",
            "./utilities",
            "./utilities/histogramUtilities",
            "./utilities/awkwardArray",
            "./MLFramework",
            "./MLFramework/module",
            "./limitsProducer"
        ],
    }
}

Replace /work/fleble/anaconda3/envs/svj13/bin/python by your own Python installation if you have any.

Now:

• Open VSCode
• Install the Remote Explorer extension
• Open the Remote Explorer extension in the left hand-side panel and click on the small window next to t3ui01.psi.ch. If you overlay the mouse on it, it dislays Connect in New Window.
• Enter your password, the new window is now connected to the T3.
• In the menu bar, click on File and then open Workspace from File. Browse to open ~/SVJanalysis/svj_analysis.code-workspace.
• Type your password again, and the new window should now be connected to the repository.
• Close the window and open a new empty VSCode window.
• Below t3ui01.psi.ch you should now see svj_analysis (Workspace). Click on the small window to Connect in New Window. This automatically opens the repository (after your enter your password).

If not already done, to avoid entering your password all the time, follow instructions here: Password-less ssh setup.

Install the following extensions:

• Python
• Pylance
• Python Debugger
• isort
• Jupyter
• Jupyter Notebook Renderers
• LaTex Workshop
• LTex - LanguageTool grammar / spell checking
• ROOT file viewer
• vscode-pdf

This has to be done on the remote server.
You can also install the extensions you want locally on your laptop!

Type F1 and search for Remote-SSH: Settings.
There set the Max Reconnection Attempts to 1.
In case you loose internet connection, VSCode will automatically try to reconnect and after 3 failed attempt, your IP will be banned from the T3. This configuration change is to avoid that this happens!
