Fixes #117 Inside an AppImage, AppRun and the linuxdeploy GTK/GStreamer hooks point LD_LIBRARY_PATH, PATH, XDG_DATA_DIRS, GIO_MODULE_DIR, GTK_PATH, GST_PLUGIN_* … into the mounted image, and every child inherited them, so host programs loaded the image's older libraries (curl + bundled nghttp2 → symbol lookup error when installing Kotlin LSP). ide_core::process::prepare (formerly no_window) now gives children the host environment back: entries inside $APPDIR are dropped (a <NAME>_ORIG wins), emptied variables and the runtime's launch variables are removed, explicit call-site values are kept; the IDE process itself is unchanged. Covers all spawn sites that used no_window plus terminal/run PTYs, run configuration environments and stop commands, login-shell probes, attach ps/kill, docker PATH, tool search PATH and the Linux browser opener. No-op outside an AppImage. Not verified on a Linux AppImage. Claude-Session: https://claude.ai/code/session_01VUYsdXA2nkF5v6zsC93dpn

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
Build
pnpm install
pnpm tauri dev
