Nimby

7. Launch

Section 7 of 13Edit this page on GitHub

Launch page

The Launch page: server picker, BattlEye and the exact command line.

  1. Pick a server, or leave No server. The list comes from repo.json; the first entry is preselected.
  2. Tick Launch with BattlEye if the server requires it; this selects arma3battleye.exe.
  3. Preview shows the exact command line with the password redacted.
  4. Launch Arma 3 starts the game; Nimby waits until it exits.

Launch passes every mod folder in the active workspace with -mod=, plus the server address, port and password, the Parameters page entries and the repository's client parameters. If Arma is already running the launch is refused.

Parameters page

Parameters page

The Parameters page: the list, the known-parameter picker and the preview.

Parameters apply to every launch Nimby performs. Managed ones (-mod, -connect, -port, -password) are filled in from the installed mods and the server picker; user ones are yours, picked from the known list or typed as -flag or -key=value. Values with spaces are quoted automatically, and the profile name is always quoted: -name="Fred". Uncheck a parameter and press Save parameters to remove it; the preview shows the rendering without -mod and server values.

The command-line length limit

Windows caps a command line at 8191 characters, and -mod= with absolute paths eats that fast. Nimby measures the line and refuses to launch (command line would be 8632 characters (limit 8191) with 24 mods; …) instead of letting Arma fail cryptically. Fixes: move the workspace root closer to the drive root (E:\Nimby, not E:\Games\Arma Stuff\Nimby\Workspace), split unrelated mods across repositories, drop mods you do not need for that server.
