Sparky recent releases have introduced a lot of features allowing to build user interfaces for internal web applications.
In a nutshell Sparky is a web platform to run automation tasks, and Sparky equips you with a rich feature set to build a frontend to launch tasks with parameters.
HTML controls
Let's brew some coffee, even though I've been trying to slow down on caffeine recently.
allow_manual_run: true
vars:
-
name: Flavor
default: "latte"
type: select
values: [ espresso, amerikano, latte ]
-
name: Topic
default: "milk"
type: select
values: [ milk, cream, cinnamon ]
multiple: true
-
name: Step3
default: "boiled water"
type: input
This simple Sparky job definition will spin up a simple UI with 3 controls:
In Raku scenario those input parameters are handled like that:
my $flavor = tags()<Flavor>;
my $water = tags()<Step3>;
my @topics = [];
# tags() needs :array modifier
# as multiple choices are passed
for tags(:array)<Topic><> -> $t {
@topics.push: $t;
};
Simple, huh?
One more coffee, please!
Or maybe you like a tea?
Another cool feature of Sparky is a multi scenario flows or group variables. Let's say you would like to give a choice of coffer or tea, so instead of having 2 job definitions with different sets of variables, let's create just one:
vars:
# tea vars
-
name: Flavor
default: "black"
type: select
values: [ black, green ]
group: [ tea ]
-
name: Topic
default: "milk"
type: select
values: [ milk, cream ]
group: [ tea ]
# coffee vars
-
name: Flavor
default: "latte"
type: select
values: [ espresso, amerikano, latte ]
group: [ coffee ]
-
name: Topic
default: "milk"
type: select
values: [ milk, cream, cinnamon ]
group: [ coffee ]
multiple: true
# common vars
-
name: Step3
default: "boiled water"
type: input
group: [ tea, coffee ]
# every var
# in group vars
# is a separate
# scenario
group_vars:
- tea
- coffee
Now, when the job gets run, we have a choice:
And then (when click on proper link), let's enjoy some tea:
Conclusion
Sparky is a nice web console to build internal automation services with HTML and write automation scenarios with Raku. Thanks for reading.
