*This guideline is very much a work-in-progress.*
Contriubtions to `timm` for code, documentation, tests are more than welcome!
There haven't been any formal guidelines to date so please bear with me, and feel free to add to this guide.
# Code
Code linting and auto-format (black) are not currently in place but open to consideration. In the meantime, the style to follow is (mostly) aligned with Google's guide: https://google.github.io/styleguide/pyguide.html
A few specific differences from Google style (or black)
1. Line length is 120 char. Going over is okay in some cases (e.g. I prefer not to break URL across lines).
2. Hanging indents are always prefered, please avoid aligning arguments with closing brackets or braces.
Example, from Google guide, but this is a NO here:
```
# Aligned with opening delimiter.
foo = long_function_name(var_one, var_two,
var_three, var_four)
meal = (spam,
beans)
# Aligned with opening delimiter in a dictionary.
foo = {
'long_dictionary_key': value1 +
value2,
...
}
```
This is YES:
```
# 4-space hanging indent; nothing on first line,
# closing parenthesis on a new line.
foo = long_function_name(
var_one, var_two, var_three,
var_four
)
meal = (
spam,
beans,
)
# 4-space hanging indent in a dictionary.
foo = {
'long_dictionary_key':
long_dictionary_value,
...
}
```
When there is descrepancy in a given source file (there are many origins for various bits of code and not all have been updated to what I consider current goal), please follow the style in a given file.
PR with pure formatting / style fixes will be accepted but only in isolation from functional changes, best to ask before starting such a change.
# Documentation
As with code style, docstrings style based on the Google guide: guide: https://google.github.io/styleguide/pyguide.html
The goal for the code is to eventually move to have all major functions and `__init__` methods use PEP484 type annotations.
When type annotations are used for a function, as per the Google pyguide, they should **NOT** be duplicated in the docstrings, please leave annotations as the one source of truth re typing.
There are a LOT of gaps in current documentation relative to the functionality in timm, please, document away!
# Questions
If you have any questions about contribution, where / how to contribute, please ask in the Discussions (there is a `Contributing` topic).
