## What was the problem/requirement? (What/Why)
Frequently, I wish to cancel the processing of images, but also want the
current image to finalize before I do. To work around this, I need to
wait until the current one finishes before pressing the cancel.
## What was the solution? (How)
* Implemented a button that allows to "Cancel after current iteration,"
which stores a state in the UI that will attempt to cancel the
processing after the current image finishes
* If the button is pressed again, while it is spinning and before the
next iteration happens, this will stop the scheduling of the cancel, and
behave as if the button was never pressed.
### Minor
* Added `.yarn` to `.gitignore` as this was an output folder produced
from following Frontend's README
### Revision 2
#### Major
* Changed from a standalone button to a context menu next to the
original cancel button. Pressing the context menu will give the
drop-down option to select which type of cancel method the user prefers,
and they can press that button for canceling in the specified type
* Moved states to system state for cross-screen and toggled cancel types
management
* Added in distribution for the target yarn version (allowing any
version of yarn to compile successfully), and updated the README to
ensure `--immutable` is passed for onboarding developers
#### Minor
* Updated `.gitignore` to ignore specific yarn folders, as specified by
their team -
https://yarnpkg.com/getting-started/qa#which-files-should-be-gitignored
## How were these changes tested?
* `yarn dev` => Server started successfully
* Manual testing on the development server to ensure the button behaved
as expected
* `yarn run build` => Success
### Artifacts

(Scheduled cancel selected and running)
(Scheduled cancel started)
## Notes
* Using `SystemState`'s `currentStatus` variable, when the value is
`common:statusIterationComplete` is an alternative to this approach (and
would be more optimal as it should prevent the next iteration from even
starting), but since the names are within the translations, rather than
an enum or other type, this method of tracking the current iteration was
used instead.
* `isLoading` on `IAIIconButton` caused the Icon Button to also be
disabled, so the current solution works around that with conditionally
rendering the icon of the button instead of passing that value.
* I don't have context on the development expectation for `dist` folder
interactions (and couldn't find any documentation outside of the
`.gitignore` mentioning that the folder should remain. Let me know if
they need to be modified a certain way.
- The checkpoint conversion script was generating diffusers models with
the safety checker set to null. This resulted in models that could not
be merged with ones that have the safety checker activated.
- This PR fixes the issue by incorporating the safety checker into all
1.x-derived checkpoints, regardless of user's nsfw_checker setting.

Also tighten up the typing of `device` attributes in general.

Weblate's first PR was it attempting to fix some translation issues we
had overlooked!
It wanted to remove some keys which it did not see in our translation
source due to typos.
This PR instead corrects the key names to resolve the issues.
# Weblate Translation
After doing a full integration test of 3 translation service providers
on my fork of InvokeAI, we have chosen
[Weblate](https://hosted.weblate.org). The other two viable options were
[Crowdin](https://crowdin.com/) and
[Transifex](https://www.transifex.com/).
Weblate was the choice because its hosted service provides a very solid
UX / DX, can scale as much as we may ever need, is FOSS itself, and
generously offers free hosted service to other libre projects like ours.
## How it works
Weblate hosts its own fork of our repo and establishes a kind of
unidirectional relationship between our repo and its fork.
### InvokeAI --> Weblate
The `invoke-ai/InvokeAI` repo has had the Weblate GitHub app added to
it. This app watches for changes to our translation source
(`invokeai/frontend/public/locales/en.json`) and then updates the
Weblate fork. The Weblate UI then knows there are new strings to be
translated, or changes to be made.
### Translation
Our translators can then update the translations on the Weblate UI. The
plan now is to invite individual community members who have expressed
interest in maintaining a language or two and give them access to the
app. We can also open the doors to the general public if desired.
### Weblate --> InvokeAI
When a translation is ready or changed, the system will make a PR to
`main`. We have a substantial degree of control over this and will
likely manually trigger these PRs instead of letting them fire off
automatically.
Once a PR is merged, we will still need to rebuild the web UI. I think
we can set things up so that we only need the rebuild when a totally new
language is added, but for now, we will stick to this relatively simple
setup.
## This PR
This PR sets up the web UI's translation stuff to work with Weblate:
- merged each locale into a single file
- updated the i18next config and UI to work with this simpler file
structure
- update our eslint and prettier rules to ensure the locale files have
the same format as what Weblate outputs (`tabWidth: 4`)
- added a thank you to Weblate in our README
Once this is merged, I'll link Weblate to `main` and do a couple tests
to ensure it is all working as expected.
This fixes a few cosmetic bugs in the merge models console GUI:
1) Fix the minimum and maximum ranges on alpha. Was 0.05 to 0.95. Now
0.01 to 0.99.
2) Don't show the 'add_difference' interpolation method when 2 models
selected, or the other three methods when three models selected
