How do I edit/create code snippets?

The 2021 release allows the insertion of code snippets. I can't find any information in the docs about this other that to use alt-ins to insert a snippet. Some questions.

1) The option key on the mac subs for alt, but where is the ins(ert?) key?
2) How do I create a new snippet?
3) How do I edit an existing snippet?

No idea where that key is on Mac, but the code snippets can
be also inserted via context menu (normally right click in
the editor, wherever that is on Mac, probably CTRL+Click?)

> 2) How do I create a new snippet?

There's no GUI for that yet. Maybe that will happen at some
point but right now it's all manual work.

1) Go to config directory (create if it does not exist)

The folder name can be found in Help->Library Info->User
Config Path

2) Create a subfolder called "templates"

3) Create a text file with extension .json, for example:

File name: points.json
Content:
{
    "key" : "points",
    "content" : "points = [ for (a = [0:5:359]) 1^~^ * [ -sin(x), cos(x) ] ]"
}

The 3 chars ^~^ indicate where the cursor will end up
after the text was inserted at the current cursor location.

> 3) How do I edit an existing snippet?

Those are stored in the Application Bundle, so it might be
possible to edit those by "Show Package Content" and going
into the Contents/Resources/templates folder. I'm not sure
if that's a good option though.

For reference the files shipped in the application are:
https://github.com/openscad/openscad/tree/master/templates

ciao,

Thanks. That should be documented somewhere.

I would suggest first of all, that all templates include vectors with numbers. This is much quicker in the long run. Even when typing I do that. I type translate([0, 0, 0]), then edit. For multmatrix I would make it multmatrix([[1, 0, 0, 0], [0, 1, 0, 0], [0, 0, 1, 0]]). That’s a good starting point for that function.

Second, perhaps this is already how it works, but allow templates in the library to replace the built in ones. It would make for less confusion.

Also, in the Mac editor UI, option-leftarrow should go left one word, but it does not. This is basic mac text editing. And option-rightarrow does the “right” thing.

The OpenSCAD Manual Wiki is editable by anyone ;)
There doesn't seem to be a section this info would slot into, so if anyone wants to add this info,
I'd do it in FAQ for now. There is a bunch of similar config details that need documenting, color schemes, registry (and *nix equiv.) etc.

This is a very personal matter of taste, I would (and have in Notepad++) use
<KeyWord name="translate (["/>
So from there I just type e,g, "somevar.x, somevar.y, -1] ) " then follow on e.g. "cu" for a cube.

+1, if it doesn't now, they are in the template subdir where the .exe lives (e.g. 'My programs' for Windows).

Bob, would you be able to check the Keyboard info on GitHub from a Mac users perspective?
No need to edit it, just note anything here and I'll update it.

Sorry Bob, I wrote the first bits, where I included this at the top,

'C - Ctrl (Cmd on Mac) '

'M - Ctrl on Mac (Windows/Meta key on others) '

I should have mentioned that.

 

I did that as the GitHub Wiki is written from a developer's perspective, and so in Qt context, where:

 

'Each key code consists of a single Qt::Key value and zero or more modifiers, such as Qt::SHIFT, Qt::CTRL, Qt::ALT and Qt::META.'

'On macOS, the appropriate symbols are used to describe keyboard shortcuts using special keys on the Macintosh keyboard.'

&

'Note: On macOS, references to "Ctrl", Qt::CTRL, Qt::Key_Control and Qt::ControlModifier correspond to the Command keys on the Macintosh keyboard, and references to "Meta", Qt::META, Qt::Key_Meta and Qt::MetaModifier correspond to the Control keys. Developers on macOS can use the same shortcut descriptions across all platforms, and their applications will automatically work as expected on macOS.'

So in Function Shortcuts

Key      Modifier           Function          Notes

...

C         C         Copy selection           

V          C         Paste              

X          C         Cut selection  

 

Modifier 'C' means Command on Mac, but is technically in Qt  is CTRL, and 'M' Meta means Control on Mac. [I didn't write it]

 

In that context, I think the functions match.

Don't worry about it if you don't want to do that mental translation.

 

Re 'the entire "Mac only navigation shortcuts” should probably be eliminated. AFAIK these are in no way mac standard' they

are listed in https://support.apple.com/en-us/HT201236, is that out of date?

 

 

Michael.

I looked at it, but it will take some time to do it right.

 

First thing I noticed though is that on a Mac, there is a control key. ctrl should equal control not command. When the semantics exist on a mac like undo, cut, copy, paste the Mac shortcuts should always be used. So those four are command-z, -x, -c, -v, even though those use control- on the PC. Perhaps the problem is just the presentation. Better I think would be a table with rows consisting of <action> <pc shortcut> <mac shortcut> <linux shortcut>. Is there a Linux version? 

 

Second, the entire "Mac only navigation shortcuts” should probably be eliminated. AFAIK these are in no way mac standard and no one would use them.

I have a bunch of templates set up now. They work fine. (For clarification, I’m talking MAC here.)

1) I can’t set up a keyboard shortcut for Insert Template because that command does not exist in the menu tree. Apparently context menu items cannot be keyboard shortcutted. I verified this by tying the key to another command in the Edit menu and it works perfectly. Please just put Insert Template somewhere in the menu tree.

2) It would be WAY easier to maintain if you allowed an array of templates in a single file instead of requiring a single file for each template.

3) User templates do not replace the built in templates. Just the opposite. If I create a transfer template, it does not appear at all and the built in template is the only one available. I believe it would be better to reverse that.

4) I notice that option-left and option-right now work. Maybe I was mistaken before. However, shift-option-left and shift-option-right are supposed to extend the selection one word to the left or right. That is NOT working.

5) There was no OpenSCAD folder in …/Library/Application Support/. I had to create OpenSCAD/ and OpenSCAD/templates/.

Dear friends


I found many libraries for modelling srews and bolts. As my requirements
are really very low and as I am not a screw specialist who is willing to
re-invent the circle Iḿ looking for a small library only for modelling
M2-M6 threads/bolts...

any recommendations?

could you please send me one small file, which works on my
OpenScad-Installation, where I can see the syntax and the stuff with
INCLUDE ? Please.

e.g. making an M8 screw and/or a M8 bolt..


That would be great

thank you very much in advance

Thanks

   

Yes, most libraries are more concentrated on making printed parts using complex maths. My library is mainly for making accurate assembly views to make sure my printed parts fit around them. Nearly every project I build adds more parts to it. I am currently working on this perf board assembly:

   and another user of the library made this cute printer with it.   https://github.com/martinbudden/BabyCube/tree/main/BC200

Nop Head, I looked at the readme.md,

This looks like real high quality mechanical and electronic components Model library. 

Very good to know  where to look for these now!

Also very cool to have a BOM and .stl build system in Python

Thanks for sharing great Work.
