# ynh_use_go has to be used in any app scripts before using Go for the first time.
|
||||
# This helper will provide alias and variables to use in your scripts.
|
||||
#
|
||||
# To use gem or Go, use the alias `ynh_gem` and `ynh_go`
|
||||
# Those alias will use the correct version installed for the app
|
||||
# For example: use `ynh_gem install` instead of `gem install`
|
||||
#
|
||||
# With `sudo` or `ynh_exec_as`, use instead the fallback variables `$ynh_gem` and `$ynh_go`
|
||||
# And propagate $PATH to sudo with $ynh_go_load_path
|
||||
# Exemple: `ynh_exec_as $app $ynh_go_load_path $ynh_gem install`
|
||||
#
|
||||
# $PATH contains the path of the requested version of Go.
|
||||
# However, $PATH is duplicated into $go_path to outlast any manipulation of $PATH
|
||||
# You can use the variable `$ynh_go_load_path` to quickly load your Go version
|
||||
# in $PATH for an usage into a separate script.
|
||||
# Exemple: $ynh_go_load_path $install_dir/script_that_use_gem.sh`
|
||||
#
|
||||
#
|
||||
# Finally, to start a Go service with the correct version, 2 solutions
|
||||
# Either the app is dependent of Go or gem, but does not called it directly.
|
||||
# In such situation, you need to load PATH
|
||||
# `Environment="__YNH_GO_LOAD_PATH__"`
|
||||
# `ExecStart=__INSTALL_DIR__/my_app`
|
||||
# You will replace __YNH_GO_LOAD_PATH__ with $ynh_go_load_path
|
||||
#
|
||||
# Or Go start the app directly, then you don't need to load the PATH variable
|
||||
# `ExecStart=__YNH_GO__ my_app run`
|
||||
# You will replace __YNH_GO__ with $ynh_go
|
||||
#

# - $go_path: The absolute path to Go binaries for the chosen version.
