FGVIEWER(1)

💖 fgviewer — the FlightGear man pages, bestie edition 💖

okay so welcome to fgviewer(1), section 1 of the FlightGear manual pages, and babes you are about to have the best time peeking at scenery without ever launching the whole flight sim. buckle up 🎀

✨ NAME ✨

fgviewer — it's an alternative FlightGear viewer application, and honestly? it's giving backstage pass. 👑

✨ SYNOPSIS ✨

fgviewer [--fg-root rootdir] [--fg-scenery scenerydir] [--config
configfile] [--prop property value] [--renderer rend] [--hla]
[--federation fed]

look at her. all those little flags just waiting to be used. no cap. 💅

✨ DESCRIPTION ✨

so fgviewer is a viewer application — a whole separate lil program that lets you examine FlightGear scenery and objects without starting fgfs(1). like, you don't have to spin up the entire flight sim just to stare at some terrain. that's it. that's the whole vibe. 🦋✨

✨ OPTIONS ✨

• --fg-root rootdir — sets the FlightGear data root directory ($FG_ROOT) to rootdir. and if you don't set it? okay so she's not gonna panic, she'll just check the FG_ROOT environment variable, and if that's not there either, she falls back to the FlightGear data directory that got chosen back when the program was compiled. iconic fallback chain honestly 🌸
• --fg-scenery scenerydir — sets the FlightGear scenery directory ($FG_SCENERY) to scenerydir. same deal as above: no option? she peeks at the FG_SCENERY environment variable. no env var either? then it's the Scenery subdirectory inside $FG_ROOT. love a girl with a plan 💖
• --config configfile — read configuration directives straight out of configfile. 🎀
• --prop property value — set the property named property to value. simple. clean. slay. ✨
• --renderer rend — use the renderer named rend to render the scenery. > ⚠️ heads up bestie: this option is currently not supported. so like. it's here, she's pretty, but she does not work yet 😭
• --hla — enable HLA federation. federation time fr fr 🌈
• --federation fed — enable a custom federation named fed. ooh, custom. very main character energy 👑

✨ EXIT STATUS ✨

fgviewer exits with EXIT_SUCCESS when everything goes great 💚, and with EXIT_FAILURE if the syntax of the command-line arguments is wrong or an error occurs 💀. no in-between, no drama, just those two.

✨ ENVIRONMENT ✨

• FG_ROOT — if FG_ROOT is set and --fg-root is not set, it specifies the root data directory to use. 🌱
• FG_SCENERY — if FG_SCENERY is set and --fg-scenery is not set, it specifies the scenery directory to use. 🏞️

✨ FILES ✨

• $FG_ROOT/defaults.xml — the default preferences file that gets loaded on startup. she's the first one at the party 🎉
