Nodable is node-able. The goal of Nodable is to provide an original hybrid source code editor, using both textual and nodal paradigms.

Nodable is node-able !

⚠️ Disclaimer: This software is a prototype, do not expect too much from it.

The goal of Nodable is to provide an original source code editor using both textual and nodal paradigms. Via this hybrid prototype, technical and less-technical people can discuss and collaborate on the same source code.

Unlike other nodal softwares, the goal of Nodable is to make possible the edition of the source code and its graph representation at the same time. Users are not stuck into one of the two paradigms, they can go back and forth whenever they want... read more

nodable's Issues

WhileDoNode

remove CodeBlockNode

CodeBlockNode is useless since AbstractCodeBLock exists. We see this node only inside a ScopedCodeBLock. We have to remove this useless layer.

Reducing window size set it to 0x0 px by defaut.

App start with a windows maximized, if user try to go to a small sized version:

The app becomes 0 by 0 pixel sized:

Allow variable name and type edition

Auto hidden edges may be improved (min length, opacity?...)

Icon Font should be monospace to get a better text alignment in menus

The red line should be straight:

Omar tip: “Dans ImFontConfig tu peux utiliser MinAdvanceX pour rendre ta fonte d’icone monospace pour aligner les elements facilement dans le menu”.

Add an icon-only font for good vertical alignment on icon buttons

equals and parenthesis

This create a good grah but with another unconnected, like a double of what's inside parenthesis.

minimal example: a = ((4)+1)

Node connectors have an offset when document is scrolled

The active area of the node's connectors have a vertical offset when document is scrolled vertically.
When hovering them with mouse, they don't highlight.

Window can't be reduced by clicking 'exit fullscreen or reduce button)

Limit history size, or at least visible history size (ex: 100 steps, current position must be visible and centered if possible).

When creating a now using contextual menu, the new node takes current mouse pos instead of initial mouse pos.

Automatic layout cause troubles to reagence nodes

quote: "j'essaye souvent de bouger les nodes à la main pour les faire tenir tous sur un petit espace mais quand je fais ça ça en réorganise d'autres automatiquement et ça rend la tâche pas facile:

Possible solution: do not pin nodes globally, pin them relative to the parent (storing the vec2 offset)

undeclare variable when they became out of scope.

for( double i = 0; i < 10; i = i + 1 )
{
double problem_here = 10; // this line is evaluated once.
...
}

Handle when user connect different types (forbid, ask to cast, ask to change type)

• Forbid to connect an input already connected.
• Forbid to link different types except if target exists with this type.
• right click on a connector open a contextmenu (delete wire, delete wire and connected nodes)

undo/redo on value changes do not work

Connecting two instructions with no semicolon should insert a semicolon

Tabs - when a file is modified there is no feed back

Add a feedback when a file has been modified (bold font, star after/before file name, etc

Hybrid Undo/Redo

Cmd_ConnectMembers
Cmd_ConnectNodes
Cmd_DisconnectWire
Cmd_DisconnectNodes

Asm::Compiler should eval_node VariableNode input once.

See these useless eval_xxx before eval last variable:

Implem a push/pop in a stack within Asm::VM;

Wires are draw 1 frame after nodes

Consider going back to c++11

Not to use

• std:: variant
• std:: filesystem:: path
• ImFileBrowser

Isolate mode

• Is it possible to isolate the selected text while keeping the graph and locking/transparentize unwanted nodes?

ex:
int two = 2;
int twenty = two * 10;

I select:
int two = 2;
int twenty = tw[o * 1]0;

o * 1

The issue is variable name changes ("two" => "o") and cannot be connected to the existing graph. "1" could replace the value of "10" in a literal node, but again it makes no sense to connect it to the existing graph.

An input-connected Member is editable (cause infinite loops) . => lock edition when an input is connected.

ForLoopNode

Settings button size range

user quote: "j'essaye de jouer avec les variables de gui
le x de "buttons" a un max de 50 mais ça semble trop peu pour voir certains des labels des boutons"

Redo GIF with new font

new "Result" manually

Adding a new "Result" manually when cursor is not selecting (just blinking on a single line) cause serialization in loop, adding the same serialized text forever...

Node properties shows "undefined" when clicked

user quote: "quand je clique sur une valeur de sortie d'un node il affiche "uninitialized" (alors qu'a priori si) et je ne sais pas comment enlever ce message"

Hint: the property IS undefined. Probbly becquse the VM never starter. We might want to disable clicking on a property undefined in that state.

Wires and nodes have a relative vertical decal when text area is scrolled down.

Crash when shaking a node.

Parser: parse two or more instructions

Parse the as simple as possible two instructions code.
For example:

a = 10;
b = 2 * a;
// optional:
c = 1 / b;

works for single line multi instructions:

Status always says: "Everything is OK".

Should display something when parsing fails.

Suggestion: collapse instructions with their root node (if any)

user quote: " il y a un truc flou pour moi dans le code couleur des cables
je trouve qu'avoir un cable d'une couleur (vert) pour le code flow et d'une autre (blanc) pour les variables c'est cool
mais dans ce cas je trouve ça étonnant que le cable qui relie une variable à une instruction soit vert
même si en fait je comprends la logique et dans une boucle for par exemple ça fait plus de sens
mais ça ne serait pas plus concis comme ça visuellement ?"

Creating a node by dragging a member input do not update recursively its output-connected Nodes.

Cascaded '=' do not work.

Ex with: a = b = c + 10
b and c + 10 will be linked to a...

Parenthesis in ConditionalStructNode are not Tokens, so prefix/suffix are lost.

le range de "node connector padding" est bizarre

Infinite loops are allowed an make the program crash

create a wire that result in a cycle: app crashes (stack overflow ^^).
->> use a NodeEvaluator instead of eval node internaly

Fix blurry font

Update with variable cause cycles (Traversal detect it and do not crash), this cause some Nodes to stay "dirty" permanently.

Expose the whole config to the settings UI

user quote: "ok je n'avais surtout pas saisi la règle qui définissait en quoi les points sont connectés ou non, si c'est une histoire de distance ça me paraît logique bien que peu courant, ça pourrait être paramétrable quelque part"

Variable used in operator/function loose their Token prefix/suffix causing differences with original code.

Delete a node makes nodable crash

Distinguish Unable to parse expression and expression is void (ex: comments, multi line comments, empty line)

History: missing current history step in UI. => unable to redo the last command with the UI.

programNode view is not well positionned

SwitchCaseNode

Tabs - clicking on currenlty active tabs reload it

Instead, should do nothing.
