Environment variables sit between flags and fpack.yaml in precedence: a flag beats a variable, a variable beats the file. This page lists every variable fpack reads, grouped by purpose. For how to use them for secrets, see
Secrets and variables.

FPACK_LANG |
zh
/
en
(default: the OS language – see
Output language
)
|
NO_COLOR / FPACK_NO_COLOR / FORCE_COLOR |
colors |
FPACK_CORE | use this native core binary (development) |
FPACK_HOME | core cache directory |
FPACK_REBUILD=1 |
build the core with local Go first (after changing the Go sources) |
FPACK_GO |
the Go used for the fallback build (none disables local builds) |
FPACK_NO_DOWNLOAD=1 / FPACK_DOWNLOAD_URL |
never download (build locally) / download mirror (intranet); see how the launcher finds the native core |
Output language#
fpack (the Go core and the Dart launcher) speaks Chinese when your operating system's language is Chinese (any
zh variant: Simplified, Traditional, Hong Kong…) and English otherwise. Everything follows it: messages, help,
doctor / list output, error hints, the comments of the fpack.yaml
written by fpack init, and NOTARIZATION.md.
Precedence (first match wins):
--lang zh|enFPACK_LANG=zh|en-
the operating system language:
- macOS: the first language in System Settings → General → Language & Region (
defaults read -g AppleLanguages), thenAppleLocale. Terminal usually setsLANGfrom the region (oftenen_US.UTF-8even with a Chinese UI), soLANG/LANGUAGEare only used if that lookup fails; an explicitLC_ALLorLC_MESSAGESstill wins. The result is cached in~/Library/Caches/fpack/os-languageand refreshed when the system preferences change. - Windows: the user's display language (
GetUserDefaultUILanguage, no subprocess);LANGset by Git Bash/MSYS is ignored, an explicitLC_ALL/LC_MESSAGESstill wins. - Linux and others:
LC_ALL,LC_MESSAGES,LANGUAGE(first entry),LANG;C/POSIXare skipped.
- macOS: the first language in System Settings → General → Language & Region (

输出语言#
fpack（Go 核心和 Dart 启动器）在操作系统语言为中文（任何 zh 变体：简体、繁体、香港等）时使用中文，其余情况一律使用英文。所有内容都随之切换：提示信息、帮助、doctor
/ list 输出、错误提示、fpack init 生成的 fpack.yaml 注释，以及 NOTARIZATION.md。
优先级（先匹配者生效）：
--lang zh|enFPACK_LANG=zh|en-
操作系统语言：
- macOS：系统设置 → 通用 → 语言与地区 中的第一个语言（
defaults read -g AppleLanguages），其次AppleLocale。终端通常按“地区”设置LANG（即使界面是中文也常为en_US.UTF-8），所以只有读取失败时才使用LANG/LANGUAGE；显式设置的LC_ALL或LC_MESSAGES仍然优先。结果缓存在~/Library/Caches/fpack/os-language，系统偏好设置变化后自动刷新。 - Windows：用户的显示语言（
GetUserDefaultUILanguage，不启动子进程）；忽略 Git Bash/MSYS 设置的LANG，显式的LC_ALL/LC_MESSAGES仍然优先。 - Linux 等：依次读取
LC_ALL、LC_MESSAGES、LANGUAGE（第一项）、LANG；跳过C/POSIX。
- macOS：系统设置 → 通用 → 语言与地区 中的第一个语言（
