[Service Studio] possibility to make angles to connector lines

Service Studio
I usually use empty Assign actions, that don't do anything, labeled "NOP", to help me organize the flow in a action.
As a note, this doesn't have any impact in SU (Software Unit) counting because the Assign action is empty.
This solution works for me, but it would be more visually helpful if this specific action NOP existed and had a different image than the Assign image, something like a circle, in coerence with the triangle for the Start action and the Square for the End action.

Additionally, by default this action would be named NOP, but optionally the developer could change it's label to use it like a comment in the flow.
I sometimes need to add a comment in the flow, to clarify the functionality, but since comments appear in big yellow rectangles it's makes it difficult to organize the flow.
For instance, in Assign actions, the label can be a long text, that is truncated by Service Studio when displayed, but when hovering the mouse cursor over the Assign action the full text appears in a pop balloon, making it easy to read the full text.
As comment, the image of this action with be in yellow.

Besides, this doesn't seem to be very difficult to implement, as this NOP action is already very similar with the Assign action.

Like the idea, I also use some empty assigns (I call them NONE) to make the flow more 'readble'.

I only think this option could be realised by being able to set the arrow of the flow different (with cornors for instance). On this way you don't need a widget in you're flow to make the flow 'readble'.

This is also something you could use with you're comments, instead of having one straigt line to the widget.

Regarding trough you option about the widget labels, maybe it's some adding value to the following post:

instead of using NOP's I rather like this idea, to be able to angle the lines :

I agree with Joost, being able to angle the lines seems "cleaner" than dummy actions in the flow.

I have to also agree that being able to angle the lines is "cleaner" than dummy actions in the flow. That would be the perfect solution.
But, still though, I would like the "comment action" I mentioned. That is, comments would be part of the flow itself.

comments are not part of the flow, so would be a bit strange to incorporate them in the flow.

why do you think comments should be in the flow?
it's only a comment about certain action-parts.

perhaps this idea would suit you also?

Hello,

Currently, the arrows used in the flows are straight lines. In some cases, the flow could be made more reasible if it would be possible to use arrow in different part.

As the goal is not to use this very often, I might e.g. be a new icon in the toolbox.



The new way would then be something like this:

Kurt,
We have also had this readability issue in big diagrams - there is an inelegant {IMO} solution of adding a 'Dummy' Empty Assign block where you want the corners but I'd much prefer the ability (as with other tools) to just click at the point you want a corner and drag it out - I think these are known as 'waypoints' in some tools - then you could do to any flow after it is added - a separate tool is counter intuitive as it still has the same meaning with or without the bends!

Using the dummy assign trick quite often, but it would be better if we could created some corners. Also, not just corners but curved arrows as well: it has always bugged me that if you have one action going from and to the For Each, Service Studio gives you two nice curved arrows, but when adding a second action the arrow from that to the For Each is straight again, so you have to reposition it.

I am tired of seeing people use empty Assigns just to be able to route the arrows. We should have a widget or a way to set a movable "corner" for the arrows instead for this.

Referring to this discussion, perhaps create a component that does nothing. Its sole purpose would be to assist in making the flows more organised.

This will be well received by those of us with OCD. There is nothing more frustrating than having one too few components for a symmetrical or well-organised layout.

Hi,

I have some juniors working under me and they have practice to mix the code just to connect the node.

As a practice, I use empty assignment operator to connect different nodes but they are confused why I am using that operator and thought it is some code.

So we should have one widget called as empty or connector which will represent that it is just used to make the code more clean.

Thanks and Regards,

Suraj Borade

Hi Suraj Borade,

If Juniors are confused it is because it's no clear enough. You should name your "empty" assign element/node with something more meaningful and well defined other than ".", like for instance: "None", "Empty", "Dummy". This way I think it is more clear. Also, it makes easier to find those elements/nodes by searching for the specific text, if the case is needed.

This is also not the perfect solution but one better that we can use.

Best regards,

Tiago Bernardo

I often use assigns as connection points for complex actions to keep the action neat (no overlapping lines) and help to maintain the code flow without the need of a plotter.  It would be nice to be able to drag a "light grey dummy" bubble or re-color an assign bubble to further keep things neat and help focus the eye on the flow.

Merged this idea with 'Add new Widget to allow better code arrangement.' (created on 21 Dec 2018 17:18:59 by Emídio Correia)

Sometimes we use the 'assign' widget with label 'Dummy' , a 'dot' or something like that, but only to allow a better code arrangement.

My idea is to create an item/widget for this purpose.  Check the image attached. It could be similar but with an 'D' or 'arrow', for example.

Merged this idea with 'new action flow element just for design | dummy assign' (created on 16 Jan 2019 15:48:26 by trp)

Hello,

In order to organize my action flows, I tend to use a lot what we can call dummy assigns (an empty assign with a dummy label).

I think it would be helpful to have a a specific action flow element just for design / anchoring your action flow.



Best,

Tiago

In actions I sometimes want to draw lines around instead of over other parts of the algorithm.  For now I have to use an 'Assign' without assigning anything and naming it Node.  I think it would be better to be able to use real 'Do Nothing Nodes' to keep the lines of the algorithme clean.

Rather than using the empty asign element, it would be more visual if we had a flow element that only served to align the logic.


Or if we could add points where the line connecting the flow could go in another direction.


This would help to make flows that are more complex, more readable.

I believe we could benefit with a new UI element inside actions to replace dummy/empty assigns.

This could improve code readibility by getting rid of those dummy assigns or creative labels (e.g. arrows). 

Having to use it as a visual solution in such a powerful IDE seems a bit outdated, but maybe it's just me.



Yes, it will help us know the code connectors visually.

Sometimes when making action flows we can end up with really complicated or just ugly flows, which are misleading and difficult to read, for instance there's Image 1, in which cases we may turn to using empty assign nodes, like the second image.

This will help to implement complex logic in a more user friendly way to read OutSystems "code".

Every developer could potentially find this useful as there's not another option at the moment.

What is wrong with indeed creating an empty-assign and label it "NOP" or something similar?

I mean, nothing but it'd be nice to have a dedicated node and use assign nodes for their intended purpose. Also for clarity.

Merged this idea with 'Ability to organise action flows with 'Anchor Points'' (created on 02 Nov 2022 05:09:11 by Ossama Ghanem)

OutSystems action flows can grow very quickly and consequently get harder to read & follow. Connectors start to overlap and before you know it you're forced to move nodes around to attempt reading the flow.

Practices like commenting and separating flows into different actions can be definitely help however a lot of times it makes sense to have everything in one flow. 

In an attempt to significantly improve readability of action flows (and satisfy my self-diagnosed OCD ;P) is having 'Anchor Points', which would allow you pin connectors wherever you want in your flow (illustrated by the grey boxes in my examples below). Empty assign nodes can be used for this right now however that's sometimes misleading and not as aesthetically pleasing.

When your flow is getting more complex, there will be lines crossing eachother. This can become very messy. 

It would be nice to have a point/corner that you can select from widget bar, to break your lines, and create a corner, so you can go in other directions.


Hi Lander,

Although I understand your point, I suggest that you should think about how you can simplify your code, so you avoid having messy code in the first place. Maybe your action flow does too many things and you can break them into smaller pieces of code wrapped in new actions that you can call in the main flow.

Does this make sense to your use case?


Regards.

Hi Lander,

This idea has been around for a long time, so I wouldn't hold my breath for any action taken on it.  See this old idea of almost 13 years ago, still marked as 'new'.  You could go and like it...it could be merged...

I don't agree that the need for such a 'connector' automatically means that your code is too large or complex for a single action, even a simple switch with options of different flow length, results in threads that you might want to bundle up neatly after the switch to do some common post processing.

I'm sure you are familiar with this common (disappointing) work-around : an assign node that is not actually assigning anything, with a recognisable label (a dot for example)
