Hello guys.

I really like working in sublime but there’s no link right now so i elaborated an universal “Script Live-Link”

it can work with any note editor what so ever, the goal is to facilitate development of scripts and addon within blender for peoples who use different text editors.

here is the project:

[https://blenderartists.org/uploads/default/original/4X/6/0/4/604eb9928d7da5d7d95b4cc8f210e6df49ce2e67.mp4](https://blenderartists.org/uploads/default/original/4X/6/0/4/604eb9928d7da5d7d95b4cc8f210e6df49ce2e67.mp4)

> - You can choose up to 3 scripts paths at the time in the text editor T panel.

> - Once the python script path is choosed, an execute script operator will be at your disposal. (click on the operator for an direct manual execution).

> - You can create a livelink:
> - If “`EXECUTE`” is in the first line of your script, every time you save the script, it will automatically run inside of blender. it can also work with `if __name__ == " __main__": register()` which is nice for working on addons.
> 
> - If “`#EXECUTE_CUSTOM`” is in the first line of your script, every time you save the script, it will automatically create(/overwrite) a new file with the line between `#EXECUTE_START` and `#EXECUTE_STOP` then run it in blender. see examples [here](https://blenderartists.org/t/scripting-live-link/1182392/10)  
> if you choose the `#EXECUTE_CUSTOM` method, don’t forget your boundaries. as the script will be empty otherwise.
> 
> - If `#STOP` is in the first line of your script, the live-link will stop.
> 
> - **Always keep an text editor open in the blender main layout otherwise the link will not work.** i suggest you tu use a set up like this below
> 
> > **Suggested use. always keep an text edito open**
> >

> - There’s also an addon reloader operator, handy to update the code of your addon directly into blender if `if __name__ == " __main__": register()` method won’t work for you. You just need to set the path of the addon you are working on. i only support “one `.py` file” addon type. let me know if you’d like a full folder to zip & install automation

Hey thanks !  
but you can thank me once we got the `#EXECUTE` feature working.

i cracked the #execute problem with the help of kiao. im using it for my scripts right now. it’s god damn powerful. i hope the blender institute will let me make this addon official. it make a kinda universal link with any other script editor. (there’s just the step of finding script path which is annoying).

Okay. Finished.

> UPTDATE

> - ` #EXECUTE` is now working perfectly, with 3 scripts live-linked simultaneously.
> - It can not work with addon `if __name__ == " __main__": register()` which is really nice for working on an addon.

> - if your addon is too complex to be used with `if __name__ == " __main__": register()` you may directly register it inside of blender with the _addon realod_ operator.
> - personally i’m not working with .zip format with multiples scripts for one addon. so right now this operator will only work for one file `.py` addon format. Please let me know if `.zip` support important for you. i think i can automate a whole folder to `.zip` + auto addon reg.

> - **i dropped the .blend text editor live link.** as it is totally useless. i get that it’s cool but i find not utility in this. It’s worth nothing now that `#EXECUTE` is here. If you don’t agree with that let me know.

> - you have now the possibility of executing only some part of your script. for example:
> - `#EXECUTE[5]` will only execute line 5
> - `#EXECUTE[5:55]` will only execute lines 5 to 55
> - `#EXECUTE[5:10][15:16][36]` will only execute lines 5 to 10 + 15 to 16 +36
> 
> This is really useful. i tested it myself, as there’s no need to use a whole new file to do some testing.  
> it will also generate a `ScriptName_script_cut.py` file. let me know if i should automatically delete him after execution.

I could do an alternate way of doing this like `#EXECUTE BELOW` and `#STOP` directly inside of the script ? what do you think ? is this better ? i think i’ll do that right now. ?

## [Script-LiveLink\_V17.py](https://blenderartists.org/uploads/short-url/yMnDIFM04NvMuRd4rmpBxRPDnIj.py) (21.3 KB)

i had some def attribute problem in the script so there’s some horrible def repetition. it was kind of tricky to get one def working for the three custom slots at the same time. so i had to made one def per slot which is stupid. but well it is working. #don’t judge me please

> UPDATE

I Replaced the custom execution system !

if `#EXECUTE_CUSTOM` is in the firsl line instead of simply `#EXECUTE` it will only execute lines between `EXECUTE_START` and `EXECUTE_STOP`

## here’s some examples:

* * *

* * *

* * *

**Example Script 1=**

```auto
#EXECUTE
print(1)
print(2)
print(3)

```

Output:

```auto
1
2
3

```

* * *

* * *

* * *

**Example Script 2=**

```auto
#EXECUTE_CUSTOM
print(1)
#EXECUTE_START
print(2)
#EXECUTE_STOP
print(3)
print(4)
#EXECUTE_START
print(5)

```

Output:

```auto
2
5

```

* * *

* * *

* * *

`#EXECUTE_START` can also crop indentation for you

**Example Script 3=**

```auto
#EXECUTE_CUSTOM
def my_super_complex_def():
   if blabla == True:
       if 'hello' not in manywow:
           #EXECUTE_START
           print('very')    
           print('wow')    
           print('such')    
           print('handy')
#EXECUTE_STOP

```

Cutted script file will be this:

```
print('very')    
print('wow')    
print('such')    
print('handy')

```

Output:

```auto
very
wow
such
handy

```

* * *

* * *

* * *

Keep in mind that all the modules, def, and defined objects will not magically be working if not within the boundaries of the custom execution.

```auto
#EXECUTE_CUSTOM
import bpy
C = bpy.context
name = "Monkey"
print(4)
print(5)
#EXECUTE_START
C.object.name = name
#EXECUTE_STOP
print(3)
print(4)
print(5)

```

Output = `Error`

* * *

* * *

* * *

@Elreenys let me know for potential feedbacks, do you use Sublime too ? or something else ?

It’s definitively my fav addon ❤  
Just one thing, you should add an how to install it in text form, the video is a bit fast.

Sorry.

i will, in the meanwhile it’s really simple:

1)install the addon .py  
2)set up a text editor (always open) and go in the T or N panel. find out my addon category.  
3)just set your script path. you can set 3 scripts simultaneously.  
4) use #EXECUTE in the first line of your script and every time you save the script will be automatically run inside of blender.

I succeed to use it but if others wants to try it, they’ll have instructions.  
It’s CTR + T in the scripting tab to open the sidebar.

the error message is not important, it’s just that i’m trying to remove a timer something that doesn’t exist yet. I will correct that for update v20.

can i get the file that you cannot draw ? i’d like to see it for myself please, hard to tell witouth it.
