A modern, fully-featured IDE for the Julia programming language, built with Tauri 2, React, TypeScript, and Rust.

@ Rakesh - conributed a bug fix 🎉

• Monaco Editor with full Julia syntax highlighting via a custom Monarch tokenizer
• 25+ Julia snippets — function, struct, try/catch, @testset, comprehensions, macros, and more
• Tabbed multi-file editing with dirty indicators and auto-save
• Split editor — side-by-side editing with a resizable divider
• Breadcrumb navigation showing the file path below the tab bar
• Find & Replace (Cmd/Ctrl+F, Cmd/Ctrl+H) via Monaco's built-in widget
• Configurable font size, font family, tab size, word wrap, and minimap
• LaTeX to Unicode — type \alpha + Tab to insert α (based on Julia's LaTeX symbols table)

• Powered by LanguageServer.jl
• Autocompletion, hover documentation, go-to-definition, find references
• Signature help with parameter info
• Real-time diagnostics (errors and warnings) shown inline and in the Problems panel
• Error lens — inline diagnostic messages displayed at the end of each line
• InlayHints — type and parameter hints displayed inline in the editor
• Semantic tokens — rich semantic highlighting beyond syntax-level tokenization
• Workspace and document symbol search

• Run scripts with rich output — inline images (PNG, JPEG, SVG), HTML, and plain text
• Interactive REPL via xterm.js with full PTY emulation
• Multi-terminal support — create, switch, and close multiple Julia REPL sessions
• Debugger integration via Debugger.jl — breakpoints, step-through, variable inspection, call stack
• Code cell execution — ## markers create code cells; Ctrl/Cmd+Enter runs the current cell with inline results
• Variable Explorer — workspace variable introspection via the REPL with DataFrame viewer support
• Revise.jl toggle for hot-reload development
• Pluto.jl reactive notebook support — open .jl files as Pluto notebooks in a native window
• Package Manager — add and remove packages via Pkg.jl directly from the UI
• Environment selector — switch between Julia project environments

• File explorer with tree view, create/rename/delete files and folders
• Drag-and-drop to move files between directories
• File watching — automatically detects external changes (git, other editors) and refreshes the tree
• Quick Open (Cmd/Ctrl+P) — fuzzy file finder across the entire workspace
• Global Search (Cmd/Ctrl+Shift+F) — search across all files with regex, case-sensitivity, and glob filters

• Source control panel — view staged, unstaged, and untracked files
• Stage / unstage individual files or stage all at once
• Commit with a message directly from the UI
• Branch management — create, delete, and switch branches from the UI
• Push / Pull / Fetch — sync with remote repositories
• Merge — fast-forward and normal merges with conflict detection
• Stash — save, list, and pop stashed changes
• Ahead/Behind tracking — see how far your branch is from the upstream
• GitHub / GitLab / Gitea provider integration — browse PRs, issues, and CI status directly in the IDE
• Auth settings — store personal access tokens securely via the OS keychain
• Git blame — toggle inline blame annotations showing author, date, and commit summary per line
• Diff viewer — side-by-side diff view using Monaco DiffEditor
• Merge conflict resolution — detects conflict markers and provides "Accept Current", "Accept Incoming", and "Accept Both" action buttons inline
• Powered by libgit2 (via the git2 Rust crate) — no shell dependency for core operations

• Activity bar — switch between Explorer, Outline, Search, Variables, Source Control, and Dev Containers views
• Command palette (Cmd/Ctrl+Shift+P) with 35+ commands
• Settings panel (Cmd/Ctrl+,) — configure editor, terminal, and appearance
• Theme support — Dark and Light themes with full CSS variable system
• Welcome screen with recent projects on startup
• Resizable panels — sidebar and bottom panel with drag handles
• Outline panel — LSP-powered document symbol tree in the sidebar (functions, structs, modules, etc.)

• Plot Pane — image gallery in the bottom panel for plot output (PNG, JPEG, SVG, HTML)
• Test Runner — runs Pkg.test() and parses @testset results in the bottom panel
• Status bar — Julia version, environment, git branch, LSP status, Revise/Pluto indicators

• Auto-detect devcontainer.json in the workspace and offer to build/start
• Docker and Podman runtime auto-detection (with manual override in settings)
• Build, start, stop, rebuild, and tear down dev containers from the UI or command palette
• Container panel in the sidebar — list running containers and images, start/stop/restart/remove

• Plugin discovery — automatically scans ~/.julide/plugins/ for installed plugins
• Plugin manifest (plugin.json) — declare name, version, entry point, and contributions
• Plugin API — register commands, sidebar panels, bottom panels, status bar items, and toolbar buttons
• Plugin panel in the activity bar sidebar — view installed plugins and their status

• Julia 1.6 or later (download)
• Rust (latest stable) — install via rustup
• Bun — install (used as the package manager and script runner)
• System dependencies for Tauri — see Tauri prerequisites

Install these globally for the best experience:

using Pkg
Pkg.add("LanguageServer")  # LSP support
Pkg.add("Revise")          # Hot-reload
Pkg.add("Debugger")        # Debugger integration
Pkg.add("Pluto")           # Reactive notebooks

git clone https://github.com/sinisterMage/JulIde.git
cd JulIde
bun install

# Start the Tauri dev server (frontend + native window with hot reload)
bun run tauri dev

This starts Vite on localhost:1420 and opens the native Tauri window. Changes to both the React frontend and Rust backend are hot-reloaded.

# Build the distributable application
bun run tauri build

The output is placed in src-tauri/target/release/bundle/ and includes platform-specific installers (.dmg on macOS, .msi/.exe on Windows, .deb/.AppImage on Linux).

Settings are stored in ~/.config/julide/settings.json (Linux), ~/Library/Application Support/julide/settings.json (macOS), or %APPDATA%/julide/settings.json (Windows).

Available settings:

julIDE automatically finds Julia using these strategies (in order):

1. juliaPath setting (if set via Settings or the command palette "Set Julia Executable Path")
2. $JULIA_PATH environment variable
3. Login shell which julia lookup
4. ~/.juliaup/bin/julia (juliaup default)
5. Common paths: /opt/homebrew/bin/julia, /usr/local/bin/julia, /usr/bin/julia
6. macOS /Applications/Julia*.app bundles

If Julia is not found, use the command palette (Cmd/Ctrl+Shift+P → "Set Julia Executable Path") to pick a custom binary, or set the JULIA_PATH environment variable.
