Adding new Snap settings to code

Changes to config

1) Add to beginning

At beginning there is this line:

# list of supported keys
keys="MONGODB_BIND_UNIX_SOCKET MONGODB_BIND_IP ..."

To the end of it, add name of new setting. For example:

keys="... AWESOME_FEATURE_ENABLED"

2) Add to bottom

Example 1: Set features not enabled as default.

DESCRIPTION_LDAP_ENABLED="LDAP enabled. Default: false"
DEFAULT_LDAP_ENABLED="false"
KEY_LDAP_ENABLED="ldap-enabled"

Example 2: If setting is different for every server, leave it empty.

DESCRIPTION_OAUTH2_TOKEN_ENDPOINT="OAuth2 token endpoint. Example: /oauth/token"
DEFAULT_OAUTH2_TOKEN_ENDPOINT=""
KEY_OAUTH2_TOKEN_ENDPOINT="oauth2-token-endpoint"

Example 3: If there is same for every server, set it to general setting.

DESCRIPTION_LDAP_SEARCH_FILTER="LDAP search filter. Default: (&(objectCategory=person)(objectClass=user)(!(cn=andy)))"
DEFAULT_LDAP_SEARCH_FILTER="(&(objectCategory=person)(objectClass=user)(!(cn=andy)))"
KEY_LDAP_ENABLED="ldap-enabled"

Example 4: If you don't know example, just leave setting empty by default.

DESCRIPTION_TURBO_FILTER="Turbo filter. Default: ''"
DEFAULT_TURBO_FILTER=""
KEY_TURBO_FILTER="turbo-filter"

Changes to Snap help

1) How to quote examples

Snap settings need to be lowercase, and inside single quotes. For example:

snap set wekan ldap-user-search-filter='(&(objectCategory=person)(objectClass=user)(!(cn=andy)))'

The setting inside single quotes is the actual setting.

Actual settings can include double quotes, spaces, etc, but not single quotes. For example:

snap set wekan ldap-user-search-filter='"(&(objectCategory=person)(objectClass=user)(!(cn=andy)))"'

2) What to add as setting to Wekan help

Example 1:

echo -e "OAuth2 Token Endpoint. Example: /oauth/token"
echo -e "To enable the OAuth2 Token Endpoint of Wekan:"
echo -e "\t$ snap set $SNAP_NAME OAUTH2_TOKEN_ENDPOINT='/oauth/token'"
echo -e "\t-Disable the OAuth2 Token Endpoint of Wekan:"
echo -e "\t$ snap set $SNAP_NAME OAUTH2_TOKEN_ENDPOINT=''"
echo -e "\n"

So all you add need to be above of this line:

# parse config file for supported settings keys
