## Config panel are available from webadmin > Apps > YOUR_APP > Config Panel Button
## Those panels let user configure some params on their apps using a friendly interface,
## and remove the need to manually edit files from the command line.
## From a packager perspective, this .toml is coupled to the scripts/config script,
## which may be used to define custom getters/setters. However, most use cases
## should be covered automagically by the core, thus it may not be necessary
## to define a scripts/config at all!
## -----------------------------------------------------------------------------
## IMPORTANT: In accordance with YunoHost's spirit, please keep things simple and
## do not overwhelm the admin with tons of misunderstandable or advanced settings.
## -----------------------------------------------------------------------------
## The top level describe the entire config panels screen.
## The version is a required property.
## Here a small reminder to associate config panel version with YunoHost version
## | Config | YNH | Config panel small change log |
## | ------ | --- | ------------------------------------------------------- |
## | 0.1 | 3.x | 0.1 config script not compatible with YNH >= 4.3 |
## | 1.0 | 4.3.x | The new config panel system with 'bind' property |
version = "1.0"
## (optional) i18n property let you internationalize questions, however this feature
## is only available in core configuration panel (like yunohost domain config).
## So in app config panel this key is ignored for now, but you can internationalize
## by using a lang dictionary (see property name bellow)
# i18n = "prefix_translation_key"
################################################################################
#### ABOUT PANELS
################################################################################
## The next level describes web admin panels
## You have to choose an ID for each panel, in this example the ID is "main"
## Keep in mind this ID will be used in CLI to refer to your question, so choose
## something short and meaningfull.
## In the webadmin, each panel corresponds to a distinct tab / form
[main]
## Define the label for your panel
## Internationalization works similarly to the 'description' and 'ask' questions in the manifest
# name.en = "Main configuration"
# name.fr = "Configuration principale"
## (optional) If you need to trigger a service reload-or-restart after the user
## change a question in this panel, you can add your service in the list.
services = ["__APP__"]
# or services = ["nginx", "__APP__"] to also reload-or-restart nginx
## (optional) This help properties is a short help displayed on the same line
## than the panel title but not displayed in the tab.
# help = ""
############################################################################
#### ABOUT SECTIONS
############################################################################
## A panel is composed of one or several sections.
##
## Sections are meant to group questions together when they correspond to
## a same subtopic. This impacts the rendering in terms of CLI prompts
## and HTML forms
##
## You should choose an ID for your section, and prefix it with the panel ID
## (Be sure to not make a typo in the panel ID, which would implicitly create
## an other entire panel)
##
## We use the context of pepettes_ynh as an example,
## which is a simple donation form app written in python,
## and for which the admin will want to edit the configuration
[main.customization]
## (optional) Defining a proper title for sections is not mandatory
## and depends on the exact rendering you're aiming for the CLI / webadmin
name = ""
## (optional) This help properties is a short help displayed on the same line
## than the section title, meant to provide additional details
# help = ""
## (optional) As for panel, you can specify to trigger a service
## reload-or-restart after the user change a question in this section.
## This property is added to the panel property, it doesn't deactivate it.
## So no need to replicate, the service list from panel services property.
# services = []
## (optional) By default all questions are optionals, but you can specify a
## default behaviour for question in the section
optional = false
## (optional) It's also possible with the 'visible' property to only
## display the section depending on the user's answers to previous questions.
##
## Be careful that the 'visible' property should only refer to **previous** questions
## Hence, it should not make sense to have a "visible" property on the very first section.
##
## Also, keep in mind that this feature only works in the webadmin and not in CLI
## (therefore a user could be prompted in CLI for a question that may not be relevant)
# visible = true
########################################################################
#### ABOUT QUESTIONS
########################################################################
## A section is compound of one or several questions.
## ---------------------------------------------------------------------
## IMPORTANT: as for panel and section you have to choose an ID, but this
## one should be unique in all this document, even if the question is in
## an other panel.
## ---------------------------------------------------------------------
## You can use same questions types and properties than in manifest.yml
## install part. However, in YNH 4.3, a lot of change has been made to
## extend availables questions types list.
## See: TODO DOC LINK
[main.customization.project_name]
## (required) The ask property is equivalent to the ask property in
## the manifest. However, in config panels, questions are displayed on the
## left side and therefore have less space to be rendered. Therefore,
## it is better to use a short question, and use the "help" property to
## provide additional details if necessary.
ask.en = "Name of the project"
## (required) The type property indicates how the question should be
## displayed, validated and managed. Some types have specific properties.
##
## Types available: string, boolean, number, range, text, password, path
## email, url, date, time, color, select, domain, user, tags, file.
##
## For a complete list with specific properties, see: TODO DOC LINK
type = "string"
########################################################################
#### ABOUT THE BIND PROPERTY
########################################################################
## (recommended) 'bind' property is a powerful feature that let you
## configure how and where the data will be read, validated and written.
## By default, 'bind property is in "settings" mode, it means it will
## **only** read and write the value in application settings file.
## bind = "settings"
## However, settings usually correspond to key/values in actual app configurations
## Hence, a more useful mode is to have bind = ":FILENAME". In that case, YunoHost
## will automagically find a line with "KEY=VALUE" in FILENAME
## (with the adequate separator between KEY and VALUE)
##
## YunoHost will then use this value for the read/get operation.
## During write/set operations, YunoHost will overwrite the value
## in **both** FILENAME and in the app's settings.yml
## Configuration file format supported: yaml, toml, json, ini, env, php,
## python. The feature probably works with others formats, but should be tested carefully.
## Note that this feature only works with relatively simple cases
## such as `KEY: VALUE`, but won't properly work with
## complex data structures like multilin array/lists or dictionnaries.
## It also doesn't work with XML format, custom config function call, php define(), ...
## More info on TODO
# bind = ":/var/www/__APP__/settings.py"
## By default, bind = ":FILENAME" will use the question ID as KEY
## ... but the question ID may sometime not be the exact KEY name in the configuration file.
##
## In particular, in pepettes, the python variable is 'name' and not 'project_name'
## (c.f. https://github.com/YunoHost-Apps/pepettes_ynh/blob/5cc2d3ffd6529cc7356ff93af92dbb6785c3ab9a/conf/settings.py##L11 )
##
## In that case, the key name can be specified before the column ':'
bind = "name:/var/www/__APP__/settings.py"
## ---------------------------------------------------------------------
## IMPORTANT: other 'bind' mode exists:
##
## bind = "FILENAME" (with no column character before FILENAME)
## may be used to bind to the **entire file content** (instead of a single KEY/VALUE)
## This could be used to expose an entire configuration file, or binary files such as images
## For example:
## bind = "/var/www/__APP__/img/logo.png"
##
## bind = "null" can be used to disable reading / writing in settings.
## This creates sort of a "virtual" or "ephemeral" question which is not related to any actual setting
## In this mode, you are expected to define custom getter/setters/validators in scripts/config:
##
## getter: get__QUESTIONID()
## setter: set__QUESTIONID()
## validator: validate__QUESTIONID()
##
## You can also specify a common getter / setter / validator, with the
## function 'bind' mode, for example here it will try to run
## get__array_settings() first.
# bind = "array_settings()"
## ---------------------------------------------------------------------
## ---------------------------------------------------------------------
## IMPORTANT: with the exception of bind=null questions,
## question IDs should almost **always** correspond to an app setting
## initialized / reused during install/upgrade.
## Not doing so may result in inconsistencies between the config panel mechanism
## and the use of ynh_add_config
## ---------------------------------------------------------------------
