IDE

General

Local exlude from git: .git/info/exclude, great for ignoring IDE specific files

Zed

• fast: written in Rust
• minimalistic: no distraction, no bambilion of plugins needed

Configuration tips

Local config files are in project_root/.zed/ and global config is in ~/.config/zed/. Typical files: settings.json for general settings, keybindings.json for shortcuts, snippets.json for code snippets, extensions.json for extensions, tasks.json for tasks, launch.json for launch configurations.

1) Default terminal to fish (settings.json):

"terminal": {
  "shell": {
    "program": "fish",
  },
},

2) Hide dirs like __pycache__ and .venv in the project tree (settings.json):

"file_scan_exclusions": [
  "**/.git",
  "**/.svn",
  "**/.hg",
  "**/CVS",
  "**/.DS_Store",
  "**/Thumbs.db",
  "**/.classpath",
  "**/.settings",
  "**/__pycache__",
  "**/.venv",
  "**/.idea",
]

"ui_font_size": 16,
"buffer_font_size": 14.0,
"theme": {
  "mode": "system",
  "light": "One Light",
  "dark": "One Dark Pro",
},  

{
  "file_types": {
    "Jinja2": ["html"],
  },
  "languages": {
    "Jinja2": {
      "formatter": {
        "external": {
          "command": "uv",
          "arguments": [
            "run",
            "djlint",
            "-",
            "--reformat",
            "--profile=jinja",
            "--preserve-blank-lines",
          ],
        },
      },
    },
  },
}

[
  {
    "label": "1 Lint",
    "command": "uv run ruff format . && uv run ruff check .",
    "use_new_terminal": false,
    "allow_concurrent_runs": false,
    "reveal": "always",
    "hide": "never",
    "shell": {
      "program": "sh",
    },
    "show_summary": true,
    "show_command": true,
    "tags": ["ci", "ruff"],
  },
]

6) Turn off autoformating for one format, settings.json:

{
  "languages": {
    "YAML": {
      "formatter": "language_server",
    },
  },
  "lsp": {
    "yaml-language-server": {
      "settings": {
        "yaml": {
          "format": {
            "enable": false,
          },
        },
      },
    },
  },
}

Multi-Profile & Copilot Isolation (Linux)

The Problem: GitHub Copilot stores its authentication token globally per OS user inside ~/.config/github-copilot/hosts.json. Because Zed lacks native multi-profile switching, it will always use this single global identity. Furthermore, browser security features like Multi-Account Containers disrupt desktop application OAuth redirection, resulting in account mismatches.

The Solution: XDG Environment Isolation.

To bypass this limitation, you can force Zed into an isolated "sandbox" profile by overriding Linux XDG base directory variables (XDG_CONFIG_HOME and XDG_DATA_HOME). This forces Zed to create separate config files, extensions, and a distinct Copilot token for each client/project context.

1. Directory Structure Setup: Create dedicated directories for the new profile (e.g., customer-a) to store its independent configuration and data state.

   mkdir -p ~/.config/zed-customerA
   mkdir -p ~/.local/share/zed-customerA
   

2. Icons & Visual Distinction To prevent deployment mistakes, use distinct window themes and separate application launcher icons for each profile. Default Icon Location: ~/.local/zed.app/share/icons/hicolor/512x512/apps/zed.png Setup Custom Icon: Copy the default icon to the profile folder and alter its hue (via GIMP) or replace it with a colored alternative.
3. CLI Execution & Shell Alias To launch the isolated instance from the terminal, inject the environment variables before invoking the binary: XDG_CONFIG_HOME=~/.config/zed-customerA XDG_DATA_HOME=~/.local/share/zed-customerA ~/.local/zed.app/bin/zed .
4. GNOME Desktop Integration To make the profile searchable via the Super key and pinnable to the GNOME Dash/Dock, create a custom desktop launcher entry. Note: .desktop files do not support the tilde (~) shortcut. Absolute file paths must be declared.

   [Desktop Entry]
   Type=Application
   Name=Zed (Customer A)
   Comment=Isolated Zed Profile for Customer A Workflow
   Exec=env XDG_CONFIG_HOME=/home/<user>/.config/zed-customera XDG_DATA_HOME=/home/<user>>/.local/share/zed-customera /home/<user>>/.local/zed.app/bin/zed %U
   Icon=/home/<user>/.config/zed-customera/icon.png
   Terminal=false
   Categories=Development;TextEditor;
   StartupNotify=true
   StartupWMClass=zed
   

5. How to verify which account:
6. In ZED: ctrl+shift+P -> zed: open log -> search user
7. From gh copilot config: sqlite3 ~/.config/zed-<customer>/github-copilot/auth.db "SELECT user_login FROM oauth_tokens;"

PyCharm

When you have package / src layout, you need to mark src as "Sources Root" in PyCharm to proper autohelp etc.
