This seems only to be an issue while developing with reloading (via auto_load.py). When the addon gets registered the normal way in the preferences it seems to always work.

When classes in a file get registered they seem not to be registered in any deterministic order.
The Problem occurs when Panels with "bl_parent_id" try to get registered but the parent panel is not registered yet.
When repeatedly saving the file (triggering a reload) sometimes it works which seems to suggest the registration order is somehow random. The subpanels also appear in random order inside the parent when it works.

Sample ui panels file:
https://gist.github.com/florianfelix/4cfdff72c4c3e4864384e42c19ab082a

Is there maybe already any way to force some kind of registration order on the classes?

There is a script test.py which only calls: bpy.ops.wm.open_mainfile(filepath=os.path.abspath("./myProject.blend"))

The evaluated file path is OK. While the call is being executed the following error happens:

Got GET: {'type': 'ping'}

after which, the Blender process crashes and test.py becomes read-only.

If a script is executed using a shell like:
blender --background --python test.py
everything executes OK

Hello,
I get the error "Unable to import 'bpy' pylint(import-error) [1,1] for anything blender.

Note I'm running Blender 2.80.75, VSCode version 1.38.1, Python 3.7.4 64bit, on a Windows 10 OS, and the latest extensions for Blender Development and Linting, debugging (which Blender Development addon needs).

It also errors on any Blender code.

Any help would be greatly appreciated :)

VSCode pic enclosed.

Essentially everything works fine but at some random point using the "Reload Addons" action will do nothing. Blender is still active at this point, as-is the actual debugger connection (can set breakpoints and have them be hit). The only way to get out of the state is to shutdown Blender and then use the "Start" action again.

I haven't been able to spot the exact pattern that triggers the issue but I'd be open to helping debug (I haven't found a good spot in the addon code to do additional tracing or checking etc)

Nothing is printed inside the Terminal pane -- usually when things work the first line printed is "Got GET: {'type': 'ping'}" but nothing will be printed when things stop working.

I have tried manually upgrading all the packages listed, but it never seems to resolve the issue. I have uninstalled and reinstalled VS Code, all extensions, all versions of Python, etc. I can launch Blender just fine inside whatever build I make or download, but I cannot fully launch Blender VS Code using the Blender Development extension like I used to.

I'm having the same issue that was previously discussed, but the solution was very vague or non-existent. I have no idea how to solve this. I receive the following error when trying to run "Blender: Start", which results in an instant crash of Blender. Blender loads for 2 seconds, then crashes.

I'm trying to open launch blender within vscode but an error pops up telling me the path is not blender, is very weird as it didn't happen in my other computer with same software versions: windows 10, python 3.7, and latest versions of vscode and blender 2.80.

i create a new addon ( simple) name my name
i get select the folder
and here i get the error:Cannot create new addon in this folder.

I have a single repo/workspace that contains multiple Blender addons. When I run the "Build & Start" command it doesn't seem to load up any of them. Is there currently a way to use the extension for this scenario?

If not, a useful feature might be a workspace/project setting to manually declare entry points for addons. That way you could mount and load multiple addons or select which addon to mount when running "Build & Start".

I changed it back see issue #27 to

bpy.ops.wm.addon_enable(module=addon_path.name)

and then it works.

I had problems with os.remove(link_path):
File "C:\Users\BlenderViza.vscode\extensions\jacqueslucke.blender-development-0.0.10\pythonFiles\include\blender_vscode\load_addons.py", line 39
=> PermissionError [WINERROR 5]

As administrator it deletes the targeted directory but not as user => unreliable!

My solution:
import shutil
shutil.rmtree(link_path)

So I have been happily using the extension for a while, when I just encountered a big issue. After some development, I decided to write a script which bundles my addon as a .zip file which can be loaded in Blender. As I go to Preferences -> Addons in Blender, I notice by addon is still in there, probably from all my invocations of Ctrl+Shift+P -> Blender: Start. So I click Remove, so that I can then add it again using the .zip file. Then, due to what I can, in retrospective, only phrase as a stroke of SHEER LUCK, Blender gets a permission error trying to delete a file. I think "Huh? What's this?".

PermissionError: [WinError 5] Access is denied: 'C:\\Users\\Zyl\\AppData\\Roaming\\Blender Foundation\\Blender\\2.80\\scripts\\addons\\mouse_strafing\\.git\\objects\\1c\\36adfaa8701d66ad8189eb9868acda6ba8d801'

Wait... is that my git repository? I check the addon installation in the user addon folder, to find that all this time my addon has been hooked into Blender using a symbolic link, and I almost unknowingly deleted 2 weeks of work by the click of a button. WHAT. Luckily, only the project history (.git-folder) has been destroyed. Symlinking the entire development directory into production is probably the most mental thing I have come across this year. Please reconsider this design decision.

Hi

I cant make sense of the error below if it is my addon is borking or the Vscode addon is borking. I am just trying to start Blender to see if the addon is loaded properly.

I am on Windows 10 x64 using Py 3.7.0 (system installation)

It is the default template from the addon

class MYADDONOperator(bpy.types.Operator):
    bl_idname = "object.MYADDON"
    bl_label = "MYADDON"

    def execute(self, context):

I'm running blender 2.80 from docker like this:

#!/bin/sh
exec \
  docker run -t \
  -e ADDON_DIRECTORIES_TO_LOAD \
  -e EDITOR_PORT \
  -e ALLOW_MODIFY_EXTERNAL_PYTHON \
  -e DISPLAY \

  ubuntu/blender:version3 \
  ./home/radivarig/projects/blender-env/blender-2.80-4dd0a90f4213-linux-glibc224-x86_64/blender "$@" \

I select it as blender executable after running Blender: Start, blender does opens but throws:

File "/home/radivarig/projects/blender-env/blender-2.80-4dd0a90f4213-linux-glibc224-x86_64/2.80/scripts/modules/addon_utils.py", line 351, in enable
    mod = __import__(module_name)
ModuleNotFoundError: No module named 'TestAddon'

The addon symlink is created under '/root/.config/blender/2.80/scripts/addons' inside the docker container and when I reset to factory settings or open blender by hand enabling the addon does work.

Any ideas?

When I save my code, the changes are taken into account and I can use them from Blender. Yet I get the following errors in the VSCode output:

Awesome plugin! Thank you!

I'm trying to set the Python env to Blender's bundled path, so all the Blender specific site-packages are available (i.e.- import bpy).

For example, if I try changing the VSCode Python Interpreter to the bundled Blender exe C:\Program Files\Blender Foundation\Blender 2.81\2.81\python\bin\python.exe, it doesn't stick in VSCode.

What am I missing?

Hi @JacquesLucke!
Have an error executing Blender:start command on existing add-on. Does this related to the blender's config folder?
OS Windows 10.

Just installed latest blender Beta (blender-2.80.0-git.84c06e996a7a-windows64), and then tried to run "Blender: Start" and point to the "blender.exe" and I get "Path is not Blender.". Is this related to the version of blender (since this Extension was built before the Beta release?) or something else?

For my personal use I added two convenience functions to my fork:

1. PIP-install of external modules to the bundled python.
2. Installation of the python header files (sometimes need for 1).

This might be a bit off-topic with regards to the primary intention of this (very nice) extension, but if this sounds useful to anyone, I might be able to prepare a PR.
It is only tested on macOS yet, but works for 2.80, 2.81 and 2.82 on my rig.

I have been trying to make the add-on running with the recent build (blender-2.80.0-git.030c7df19da9-windows64), but even when running just the "empty" script (created by the add-on) the command Blender: Run Script triggers an exception in Blender and shuts it down.

Blender: Start outputs:

Do you know what I did wrong?

Thank you.

I have a question about older Blender versions. Why only the 2.8 supported? Do you plan to port this to 2.79 as well? If not, why? Thanks!

I've always been interested in using blender as a cool way to teach programming, but the code->blender flow never worked well. I hope something like this can become standard practice, so bug the devs to add this to the official blender docs.

This extension is for addon development?
What about using VSCode to develop Blender C++/Python itself? Since VSCode could use CMake projects directly via this extension: https://github.com/microsoft/vscode-cmake-tools it looks that VSCode could be all in one solution for Blender development especially because it support all platforms that Blender runs on.

i don't think that this is a big problem but i thought ill report it anyways so when i create a popup like the one below and start blender trough vscode open the popup (important leave it open) and then reload the addon, click the ok button in the popup then blender crashes this behavior seems to pretty consistent.

import bpy

from cycles.ui import CYCLES_RENDER_PT_sampling, CYCLES_RENDER_PT_sampling_advanced
#from space_properties import PROPERTIES_PT_navigation_bar


class SM_Properties_Popup(bpy.types.Operator):
    bl_idname = 'sop.sm_properties_popup'
    bl_description = 'test'
    bl_label = 'Properties'

    bl_options = {'UNDO'}

    panels: dict = {}
    label: bool = True

    @classmethod
    def poll(cls, context): 
        return True #PROPERTIES_PT_navigation_bar.poll(context)


    def invoke(self, context, event):

        return context.window_manager.invoke_props_dialog(self, width=300)


    def execute(self, context):
        return {'FINISHED'}


    def draw(self, context):
        layout = self.layout


        #PROPERTIES_PT_navigation_bar.draw(self, context)

        CYCLES_RENDER_PT_sampling.draw(self, context)
        layout.label(text="Advanced")
        CYCLES_RENDER_PT_sampling_advanced.draw(self, context)

Hi

I have a script which works OK directly in Blender 2.80, but not from VSCode. The problems seem to be with the context, despite having used 'Blender:Set Script Context' = VIEW_3D. For example,

bpy.context.active_object returns None incorrectly and,

bpy.ops.object.modifier_apply gives RuntimeError: Error: Modifiers cannot be applied in edit mode despite being in Object mode.

Here is a test script which reproduces the problems

# context.area: VIEW_3D
import bpy
from mathutils import Vector

# make two icospheres and join them with Boolean union operator
# works directly from Blender 2.80 python editor
# fails running from VSCode using remote Blender Development plugin

# make new sphere object
bpy.ops.mesh.primitive_ico_sphere_add(location=Vector((0,0,0)), radius=1.0)
# get handle to object
ico1=bpy.context.active_object # PROBLEM - returns None
ico1=bpy.data.objects['Icosphere'] # get by name instead
# rename
ico1.name='Ico1'
ico1.data.name='Ico1'

# make new sphere object nearby
bpy.ops.mesh.primitive_ico_sphere_add(location=Vector((0.8,0,0)), radius=1.0)
# get handle to object
ico2=bpy.context.active_object # PROBLEM - returns None
ico2=bpy.data.objects['Icosphere'] # get by name instead
# rename
ico2.name='Ico2'
ico2.data.name='Ico2'

# join ico2 to ico1 by applying Boolean op
bool_mod=ico1.modifiers.new(name='bool_mod', type='BOOLEAN')
bool_mod.object=ico2
bool_mod.operation='UNION'
bpy.ops.object.modifier_apply(
	{"object": ico1},
	apply_as='DATA',
	modifier=bool_mod.name)

# but this gives ERROR - RuntimeError: Error: Modifiers cannot be applied in edit mode

Im running into a issue with opening up an addon im upgrading. I run blender run and it wont run in blender even when I run VS code as admin. Here is my log.

It seems like the Vscode addon has issues with registering this. If I start Blender the usuak way my addon loads and everything works, that is not the case when I run Blender with Blender:start

    testint = bpy.props.IntProperty(  
        name="testint",

Hi

It seems like the debugger throws an exception if a module (from the script folder) imported like

"from . MYMODULE import *"

And throws an exception like this, when the debugger is is enabled after starting Blender

Exception has occurred: ModuleNotFoundError
No module named '__main__.MYMODULE'; '__main__' is not a package
  File "C:\DEV\MYADDON\__init__.py", line 41, in <module>
    from . MYMODULE import *

Please bear in mind that Blender runs this addon no problem and MYMODULE.py is really in "C:\DEV\MYADDON" which is where __init__.py is.

Hi

I am writing a script that I will turn into an addon. When I run the script from Vscode I get bunch of errors. When load the exact same script in Blender text editor and run from there, it works perfectly. Does this sound like an Vscode issue based on the logs?

https://paste.debian.net/hidden/07afbae4/

I tried creating a script right from Vscode using the addon but I get "Cannot read property 'data' of undefined" so I just run the loaded script. It was working fine until I added obj exporting line to my code.

When executing the "Blender: New Addon" tool, I answer the prompt "Choose Template", and the tool stops. I can't find any log, or debugging information.

I may have installation issues (3 different python distributions, including Blender), but the most important problem I'm experiencing is that I'm not finding troubleshooting information in VSCode, for this Addon.

Everything was working fine until I opened a different addon folder and then switched back to my original addon folder.
Now this message (command 'whatever_the_command_is' not found) appears for every command that this extension has.
I tried reinstalling the extension and restarting vs code and my computer but that didn't help.

Hi, I'm really new to writing addons for Blender and found this amazing addon for VS code. I had some trouble with getting blender to start up and it turned out that VS code didn't have acces to the "program" folder so I cpoied Blender to a folder inside "documents" and it worked!!

Yesterday I watched the video (this one) you(Jacques Luke) did on the addon. it shows inside blender a addon that writes panels to VS code. I was immediate excited to use this feature but when I started blender it didn't show up.

So maybe someone knows why the addon inside blender isn't showing up? and how I can solve it so I can use this great addon for coding?(I hope I'm asking the right questions)

OK, well this isn’t really a bug ,but more of a question. Does the installation version of Visual Studio Code matter. I see there is User Installer, System Installer and .zip. I’m not sure which of those I should do. Never even heard of a “User Installer” before.

https://code.visualstudio.com/

Unable to open on OSX

added this to resolve the issue in blender_executable.ts

on OSX blender is packaged in a .app folder-structure which the file-selector on osx recognises as an application. but when starting from commandline, the actual binary should be executed from the folder Contents/MacOS/ inside the blender.app (folder).

Another solution would be to use the 'open' command on osx.

L#4 import * as os from 'os';`
...
L#147     (askUser_BlenderPath)
if (os.platform() === 'darwin') {
     filepath = filepath + '/Contents/MacOS/blender';
}

heh, I started a forked a while back with some tweaks to the overall layout of the vscode plugin, but now I see you´ve implemented a similar solution in the new update :)

Hi..
the extension can't recognize bpy module (neither the other blender's python API ones). So autocompletion feature is not working. What is the work around to fix that? tks

Hi

Hi

I was trying to set this up on my other Win10 system and I am getting this error. I cant find what the issue is, since I do not have tasks.json file in the folder.

The task system is configured for version 0.1.0 (see tasks.json file), which can only execute custom tasks. Upgrade to version 2.0.0 to run the task: blender: blender```

I work on and maintain a lot of addons for my studio, and the constant exceptions being raised by space_toolsystem_common.py make it really difficult to use the debugger in VSCode. One could argue that this is a bug in Blender- but honestly I should be able to use vscode's built in skipfiles configuration capabilities to just skip space_toolsystem_common.py entirely. Unfortunately this extension seems to bypass the default vscode configuration somehow, so skipfiles is ignored.

To see what I'm talking about, enable breakpoints on any raised exception then run Blender. The breakpoints are non-stop.

Starting with the bug here in case this addon is hooking into something it's not supposed to now?

Steps:

• Start with default blender scene with an addon running in vscode.
• Execute the "Blender: Reload Addons" operation

Git bisect blames the following commit: bbaa1bffe9dbc35d2791b83d0014ccb4ffb6087a

I can see the console logs inside VS Code and when I close Bledner the tasked in VScode in being closed too, so they are connected. Breakpoints don't work though

I have no clue what is causing this, because I know it worked at some point.
Currently I have my project opened in VSCode and the folder with add-on is linked inside my current blender versions script folder via a junction.
I'm running Windows 10 1903, the latest version of your add-on, vs-code and the newest build bot build of blender.

Hello,

I tried to debug an addon and it did not work. Debugging session was launching but threads never stopped on breakpoints. The addon was correctly updated.

Finally I renamed a part of the path that contained a character with an accent (é) !

Don't know if this is a limitation of your extension or the python extension itself.

Keep the good work what you do with this extension is incredible.

Hi @JacquesLucke,

first of all, great addon. Love it :) Been wanting something similar for some time now but unfortunately I've lacked the know-how to do it myself so far. I'm only getting started with Blender coding and being able to do so via VS Code is great. (Really looking forward to the code completion feature. =) )

I have a feature request: It would be great to attach the Plugin to an already running Blender process instead of having to start Blender through VS Code all the time.

Cheers
Michael

I get the error "Cannot read property 'data' of undefined" when attempting to launch Blender 2.8 (201901-07 00:16) on Windows 10 using the Ctrl+Shift+P: blender:start. I get the same error no matter what addon code/project I have loaded. The one shown in the attached image is the bundled MeasureIt addon by Antonio Vazquez.

When prompted for the Blender executable path, I've tried with/without quotes and other iterations with no effect. The path where I've got my 2.8 is:
C:\Users\WaschDL\Apps\blender-2.80.0-git.96f762500ef9-windows64\blender.exe

Latest VS-Code version. C/C++ and ms-python dependencies are installed.

Thanks!

Hi.

Seems like, this extension is great to develop a new node with native C/C++ code and then I am trying to use it.

I'd like to stay with Visual Studio 2017 community because it is free and no request about license instead of the latest 2019 version.

so, can you update the installer to support VS2017 ? or upload it to market place for VS2017 ?

I guess current version can support only VS2019 because I can't directly install it via Visual Studio Market place following the introduction video then I have downloaded the installer, but it doesn't work with error as following :

Hello,

I cannot select the Blender Executable, when I select "Blender: Start" from the prompt, the requester that appears does not allow me to move on the file system, and the Blender I have in my path is not shown.

I am on Linux (KUbuntu 18.04) with the latest stable VSCode and latest Blender 2.80 beta

I have attached a small mp4 video showing exactly what happens on my machine.

Hi

It would be very nice if the Vscode addon actually uses the bl_label to make the symbolic links in the Blender addon folder. At the moment it is using the folder name, and the folder names can be artbitrary or wrong during development. Obviously it would be nice if they match from the get go but that does not always happen depending on the situationm
