Install fenv

Install fenv using one of three modes based on the argument provided.

Mode Detection

• No argument or latest → Install latest release from remote
• snapshot → Build from local source and install
• Any other value (e.g., 0.3.0, v0.3.0) → Install specific version

Instructions

If mode is latest (or no argument):

Run:

curl -fsSL "https://fenv-install.jerry.company" | bash

If mode is snapshot:

Build from local source and install:

cargo build && cp target/debug/fenv ${FENV_ROOT:-~/.fenv}/bin/ \
  && cp shims/* ${FENV_ROOT:-~/.fenv}/shims/

If mode is a version (e.g., 0.3.0 or v0.3.0):

Install the specific version. Auto-prefix v if the version doesn't start with v:

curl -fsSL "https://fenv-install.jerry.company" |
  FENV_VERSION=v{version} bash

For example:

• 0.3.0 → FENV_VERSION=v0.3.0
• v0.3.0 → FENV_VERSION=v0.3.0
