### About --weight and --time
|
||
### ynh_script_progression will show to your final users the progression of each scripts.
|
||
### In order to do that, --weight will represent the relative time of execution compared to the other steps in the script.
|
||
### --time is a packager option, it will show you the execution time since the previous call.
|
||
### This option should be removed before releasing your app.
|
||
### Use the execution time, given by --time, to estimate the weight of a step.
|
||
### A common way to do it is to set a weight equal to the execution time in second +1.
|
||
### The execution time is given for the duration since the previous call. So the weight should be applied to this previous call.

||

### --needs_exposed_ports "$port" a list of ports that needs to be publicly exposed

|

### (N.B. DO NOT USE THIS is the port is only internal!!!)
|

###
|

### --test_status "some command" a custom command to check the status of the service

### (only relevant if 'systemctl status' doesn't do a good job)
|

###
|
||
### --test_conf "some command" some command similar to "nginx -t" that validates the conf of the service
|
||
###
|
||
### Re-calling 'yunohost service add' during the upgrade script is the right way
|
||
### to proceed if you later realize that you need to enable some flags that
