kandi X-RAY | offshoot Summary
This one day in the past, you took your first step on your programming journey. Some days were tough, some days were great. You made progress. You made mistakes. You learned some best practices and design patterns. You've come to idolize low coupling and modularity. Eventually, you started working on more ambitious projects, always increasing in complexity; the possibilities endless. After implementing your 7th export format for your latest project, the words of the great Raymond Hettinger come to mind: There's got to be a better way! After a short stint going all out on inheritance and mixins, you turn your attention to plugins. You read up on them, get the general idea and start looking at what's available for Python. You are happy to find out there are a quite a few on the market. You start trying them out and for the most part, they work great, but it always feels like something is missing. Perhaps they make you go through crazy code gymnastics, lack features or are plain just horrible to look at. This is the moment you discover offshoot.

QUESTION
Offshoot of this question: MySQL: LEFT JOIN table with preference for specific rows
I have a Contacts table, a PhoneNumbers table, and a ContactPhoneNumber table. Additionally, I have a ContactAddress and Address tables. A Contact can haveMany PhoneNumbers via the ContactPhoneNumber pivot table and can also haveMany Address via the ContactAddress table. Both a PhoneNumber and an Address can be marked as primary or not. A contact can also have no primary phone number or address or in fact no phone number or address at all.
My issue is that I need to retrieve all contacts, whether they have a phone number / address or not. Additionally, for each contact, I need to retrieve their PRIMARY phone number and address if they have one. If not, retrieve a non primary phone number / address or lastly, return no phone number / address. Joining the tables is not an issue, but I'm having trouble coming up with a way to prefer the primary phone number / address over the non primary phone number / address . Because, if I add a WHERE isPrimary = 1 to the query, it's going to now eliminate those users who don't have a primary phone number. Instead, I simply need to prefer the 1, but also be OK with a 0 if no 1 exists. My query so far is as follows:

QUESTION
I looked at an existing codebase and and I noticed that the codebase had two schema validations for what I feel a single schema could validate as the second schema is an offshoot of the first. See codebase below.
...ANSWER
Answered 2021-Mar-15 at 18:10I would argue this design pattern is the better practice, On a partial update you should have a fitting schema to represent the incoming object better. However you can avoid the two schemas while preserving the concept behind it by extending the first one using optionalKeys.
QUESTION
I’m just re(learning) python after 5+ years of inactivity; it doesn’t help that I wasn’t great at it to begin with though… Here is what I’m trying to do:
- find a sting in a file and replace it with another string (G00 with G1)
- find all of the instances where a line starts with a specific string and concatenate a string on it at the end
- The original file aaaa.gcode remains untouched and all of the changes are saved to bbbb.gcode.
Individually both sets of code work as expected. I’ve tried lots of different ways to add both sets of code together, but nothing works.
Sample file (C:\gcode\aaaa.gcode)

Answered 2020-Dec-02 at 15:53You are attempting doing .replace on file handle - this does not make sense, you should do it on line for example:
QUESTION
As an offshoot question from: IMFTransform SetInputType()/SetOutputType() fails
When I try to enumerate MP3 decoders on Windows 7 it fails to find any MP3 decoders? However it appears to find one when I set a partial media type for a IMFSourceReader for an MP3 file created by MFCreateSourceReaderFromURL.
I have tried:
...ANSWER
Answered 2020-Oct-31 at 15:36Windows 7 SP1 decoder:
MP3 Decoder MFT
- MFT_TRANSFORM_CLSID_Attribute: {BBEEA841-0A63-4F52-A7AB-A9B3A84ED38A} (Type VT_CLSID)
- MF_TRANSFORM_FLAGS_Attribute: MFT_ENUM_FLAG_SYNCMFT
- MFT_INPUT_TYPES_Attributes: MFAudioFormat_MP3
- MFT_OUTPUT_TYPES_Attributes: MFAudioFormat_PCM
The decoder does not advertise support for MFAudioFormat_Float for decoding (even tough it can support it too once instantiated). When you enumerate decoders limiting output to MFAudioFormat_Float the decoder is excluded. Newer versions of OS might either have updated decoder with more output format options.
If you did it this way:
MFT_REGISTER_TYPE_INFO outType { MFMediaType_Audio, MFAudioFormat_PCM };
or nullptr output media type, the decoder would be enumerated.
Also Source Reader API, generally speaking, uses the same MFTEnum logic in order to fit actual source media type to requested media type.
When enumerating also pay attention to flags: it might be not so important to you to pick exactly synchronous MFT, but your API call suggests you are requesting to skip asynchronous.
QUESTION
A quick google search will tell you to avoid using async void myMethod() methods when possible. And in many cases there are ways to make it possible. My question is basically an offshoot of this best practice:
What does the lambda expression below evaluate to?
...ANSWER
Answered 2020-May-15 at 20:35Yeah, it is evaluated to async Task because Task.Delay(n) has return type of Task. So it is good practice.
In addition, there is msdn example, but it is a little bit more verbose:
QUESTION
I am using Svelte Native, which is an offshoot of NativeScript. One of the libraries that I've imported has been nativescript-geolocation.
I've done this like so: import * as geolocation from "nativescript-geolocation";
This works fine when I do a cloud build and test out on my phone using tns preview
When I try and build an APK using tns cloud build android it cannot resolve the nativescript-geolocation dependency.
I get the following error:
...ANSWER
Answered 2020-Feb-20 at 12:18Seems like your build is missing the nativescript-geolocation dependency.
Running tns plugin add nativescript-geolocation should add it to package.json and fix the build.
I believe the reason it works in the preview version is that the Preview app has the geolocation plugin pre-installed.

Install offshoot
You can use offshoot like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
