zotero2readwise/__init__.py (1)
1-10: LGTM! Consider minor improvements for clarity and user feedback.The changes effectively address the issue of write permissions in read-only environments, which aligns well with the PR objectives. The implementation is correct and the added comments explain the purpose of the change.
Consider the following minor improvements:
- Make the comment more specific about which file is being written:
- # If TOP_DIR is readonly os with nix, - # then failed_zotero_items.json is written to the working directory instead. + # If TOP_DIR is read-only (e.g., when using Nix), + # then the failed_zotero_items.json file is written to the working directory instead.
- Add a log or print statement to inform the user when the fallback directory is used:
import logging # ... existing code ... FAILED_ITEMS_DIR = TOP_DIR if os.access(TOP_DIR, os.W_OK) else Path.cwd() if FAILED_ITEMS_DIR != TOP_DIR: logging.warning(f"Write access denied to {TOP_DIR}. Using {FAILED_ITEMS_DIR} for failed items instead.")These changes would enhance clarity and provide better feedback to users.
flake.nix (2)
1-4: LGTM! Consider pinning nixpkgs version for stability.The flake description and inputs are well-defined. However, for improved stability, consider pinning the nixpkgs to a specific commit or tag instead of using the unstable channel.
Example of pinning nixpkgs:
inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-23.05";
11-20: LGTM! Consider extracting the pyzotero override for better maintainability.The zotero2readwise application definition is correct and well-structured. The override for pyzotero is necessary and properly documented.
To improve maintainability, consider extracting the pyzotero override into a separate function:
let pyzoteroOverride = prev: { pyzotero = prev.pyzotero.overridePythonAttrs (old: { buildInputs = (old.buildInputs or [ ]) ++ [ prev.setuptools ]; }); }; customOverrides = defaultPoetryOverrides.extend (final: prev: pyzoteroOverride prev ); zotero2readwise = mkPoetryApplication { projectDir = ./.; overrides = customOverrides; }; inThis change will make it easier to add more overrides in the future if needed.
pyproject.toml (3)
41-41: LGTM! Consider specifying Python version compatibility.The addition of
setuptoolsas a dependency is appropriate, especially for Python 3.12 compatibility. Good job on including this with a suitable version constraint.Consider updating the
pythondependency in[tool.poetry.dependencies]to reflect compatibility with Python 3.12, e.g.,python = "^3.8,<3.13". This would make the Python version requirements more explicit and align with the setuptools addition.
48-50: LGTM! Consider a more specific script name.The addition of the script entry point is good and aligns with the PR objectives. This will allow users to easily run the main function using Poetry.
Consider using a more specific name for the script, such as
zotero2readwiseorz2r, instead ofrun. This would make the command more intuitive and avoid the repetition when usingpoetry run run. For example:[tool.poetry.scripts] zotero2readwise = "zotero2readwise.run:main"This would allow users to run the script with
poetry run zotero2readwise.
Line range hint
1-85: Consider updating Python version classifiersThe file looks good overall, with appropriate updates to the version and necessary changes for Python 3.12 compatibility.
Consider updating the
classifierssection to include Python 3.12 compatibility. Currently, it only mentions Python 3.8. You could add:classifiers = [ # ... existing classifiers ... "Programming Language :: Python :: 3.8", "Programming Language :: Python :: 3.9", "Programming Language :: Python :: 3.10", "Programming Language :: Python :: 3.11", "Programming Language :: Python :: 3.12", # ... other classifiers ... ]This would provide more accurate information about the project's Python version compatibility.
zotero2readwise/run.py (2)
50-54: Approved: New CLI flag for suppressing failure reportsThe addition of the
--suppress_failuresflag is a good feature, allowing users to control whether failed annotations are written to a report file. This aligns well with the PR objectives.Consider renaming this flag to
--suppress_failure_reportfor better clarity and consistency with the existing naming conventions in the script.
76-77: Approved: Updated Zotero2Readwise instantiationThe changes to the Zotero2Readwise instantiation correctly implement the new functionality:
- The 'since' parameter is properly set based on the --use_since flag.
- The 'write_failures' parameter is correctly set as the negation of --suppress_failures.
These updates align well with the PR objectives and the new CLI flag.
Consider renaming the
write_failuresparameter towrite_failure_reportfor consistency with the suggested CLI flag name change.zotero2readwise/zt2rw.py (3)
20-21: LGTM! Consider adding a docstring for the new parameter.The addition of the
write_failuresparameter is a good improvement, allowing users to control whether failed items are written to a file. The default value ofTruemaintains backward compatibility.Consider adding a brief description of the
write_failuresparameter in the method's docstring to improve documentation.
59-60: LGTM! Consider a minor refactoring for improved readability.The updated condition correctly implements the
write_failuresoption, ensuring that failed items are only saved if the user has opted to do so and there are actually failed items to save.Consider refactoring the condition for improved readability:
if self.write_failures and self.zotero.failed_items: self.zotero.save_failed_items_to_json("failed_zotero_items.json")This change makes the condition more concise and easier to read at a glance.
Line range hint
20-60: Summary: Newwrite_failuresoption successfully implementedThe changes in this file successfully implement the new
write_failuresoption, allowing users to control whether failed Zotero items are saved to a JSON file. The implementation is consistent across the__init__andrunmethods, and maintains backward compatibility with the default value ofTrue.Key points:
- New parameter added to
__init__method- New instance variable
self.write_failuresinitialized- Updated condition in
runmethod to use the new optionThese changes align well with the PR objectives and improve the flexibility of the library for users who may not want to save failed items.
Consider adding a configuration option or environment variable to allow users to specify the filename for failed items, instead of hardcoding "failed_zotero_items.json". This would provide even more flexibility for users with specific naming conventions or file organization needs.

flake.nix (2)
1-30: Overall, the flake looks good with room for some enhancements.The
flake.nixfile successfully defines a Nix flake for running the zotero2readwise script. It correctly sets up the necessary inputs, defines the zotero2readwise application using poetry2nix, and creates an app that can be run usingnix run.Main points for improvement:
- Enhance cross-platform compatibility by supporting multiple systems.
- Consider pinning the nixpkgs version for improved stability.
- Extract the pyzotero override for better maintainability.
- Update or remove the outdated comment in the app definition.
These changes will make the flake more robust, maintainable, and widely usable across different systems.
22-28: Update or remove the outdated comment and verify the script name.The app definition looks correct. However, there's an outdated comment that needs attention.
- Remove or update the comment on line 25 as it refers to replacing <script>, which is not applicable in the current code.
- Verify that "run" is indeed the correct script name defined in the
[tool.poetry.scripts]section of your pyproject.toml file.To verify the script name, you can run the following command:
Make sure the output contains a line like
run = "zotero2readwise.__main__:main"or similar, confirming that "run" is the correct script name.✅ Verification successful
Remove the outdated comment and confirm the script name is correct.
The app definition is accurate, and the script name "run" matches the
[tool.poetry.scripts]section in yourpyproject.tomlfile. Please remove the outdated comment to prevent any confusion.🏁 Scripts executed

zotero2readwise/run.py (3)
8-8: Excellent refactoring: Introduced main() functionEncapsulating the main logic in a
main()function is a great improvement. It enhances modularity, makes the code more testable, and follows the best practices for structuring Python scripts.
83-84: Approved: Proper script execution setupThe addition of the
if __name__ == "__main__":block calling themain()function is a standard and recommended Python practice. This setup allows the script to be both imported as a module and run directly, enhancing its versatility and maintainability.
Line range hint
1-84: Overall assessment: Well-structured and functional improvementsThe changes in this file significantly improve the script's structure and functionality:
- The introduction of the
main()function enhances modularity and testability.- The new
--suppress_failuresflag provides users with more control over error reporting.- The updated Zotero2Readwise instantiation correctly implements the new functionality.
- The script execution setup follows best practices for Python scripts.
These changes align well with the PR objectives, introducing the ability to control failure reporting and implement the 'since' functionality. The code is clean, well-structured, and maintains good practices throughout.
Consider the minor naming suggestions for consistency, but these are not critical for the functionality of the script.
zotero2readwise/zt2rw.py (1)
33-33: LGTM! Consistent with the method signature update.The new instance variable
self.write_failuresis correctly initialized with the value of thewrite_failuresparameter. This change is consistent with the method signature update and allows thewrite_failuresoption to be used in other methods of the class.README.md (2)
85-85: Approve addition of suppress_failures option.The introduction of the
--suppress_failuresoption is a valuable addition. It provides users with more control over the output and is clearly explained.
78-86: Approve overall integration of new content.The new "Approach 3" section is well-integrated into the existing documentation. Its placement at the end of the usage instructions is logical, and the consistent numbering (Approach 3) maintains the document's structure. The blank line separation helps to distinguish it from the previous approaches, enhancing readability.

🛠️ Refactor suggestion
Enhance cross-platform compatibility.
The current implementation hardcodes the system to "x86_64-linux". To improve cross-platform compatibility, consider using a more flexible approach.
Replace the hardcoded system with a dynamic approach:
outputs = { self, nixpkgs, poetry2nix }:
let
supportedSystems = [ "x86_64-linux" "x86_64-darwin" "aarch64-linux" "aarch64-darwin" ];
forAllSystems = nixpkgs.lib.genAttrs supportedSystems;
pkgs = forAllSystems (system: nixpkgs.legacyPackages.${system});
in
{
apps = forAllSystems (system: {
default = {
type = "app";
program = "${self.packages.${system}.default}/bin/run";
};
});
packages = forAllSystems (system: {
default = let
inherit (poetry2nix.lib.mkPoetry2Nix { inherit (pkgs.${system}) pkgs; }) mkPoetryApplication defaultPoetryOverrides;
in
mkPoetryApplication {
# ... rest of your mkPoetryApplication configuration
};
});
};This change will allow the flake to work on multiple architectures and operating systems.

Approve new "Approach 3" section with minor correction.
The new section effectively introduces the Nix flake approach, aligning with the PR objectives. The command format is clear, and the note about the output file location is valuable for users.
However, there's a minor grammatical error that should be corrected:
In line 84, "you working directory" should be "your working directory".
Please apply this change:
-The text file with failed highlights, which usually would be written to the Zotero2Readwise python package directory, will now be written to you working directory, since nix does not allow writing to package directories.
+The text file with failed highlights, which usually would be written to the Zotero2Readwise python package directory, will now be written to your working directory, since nix does not allow writing to package directories.📝 Committable suggestion

This pull request adds an additional way of calling Zotero2Readwise, but with no manual user installation required if they use nix.
You can already test it out with
nix run github:jjjholscher/zotero2readwise.The flake is made such that I don't expect it to require maintenance, since it uses
poetry.lockto look up dependencies.I'll explain the edits:
pyproject.toml
You use distutils, which as of python 3.12 is no longer included in the standard library, you need to include
setuptoolsmanually in the pyproject.toml if you want to continue relying on it.I picked the version to match that of pyzotero, which seems to work.
For nix to recognize
run.pyas an entrypoint for the code, I had to add it under[tool.poetry.scripts]. I think this is general good practice, now poetry will recognize it and you can call it withpoetry run run. (yes, that might be a bit confusing, I wasn't sure whether to name it zotero2readwise or main instead, such that you'd getpoetry run zotero2readwiseorpoetry run main)init.py
Your code always writes an error file to the package directory.
That's not possible in nix, so I had to include a check whether that users has write permissions there.
If not, the error file will be written to the working directory.
run.py and zt2rw.py
I assume not everyone will be glad that a
nix run github:jjjholscher/zotero2readwisecall will write a file to their working directory so I added a cli flag and a check to give the user the option for that not to happen in 102a46dIf you don't like that, you can go to 102a46d instead, which is a working version of this PR without that flag (don't mind the fact that the next commit mentions debugging, I merely neglected to refresh the flake.nix on my end, there was nothing wrong with the code)
maintenance burden
I don't expect there to be any for the next year, possibly there will literally never be any, especially if you don't change or update the code much.
Here are the two main scenarios where I envision scenarios where something should be manually updated:
If you ever choose to stop relying on
run.pyfor the CLI entry, then the[tools.poetry.scripts]section in thepyproject.tomlshould reflect that.If you ever update your dependencies and the dependencies use a new build system, the flake might complain about that. This should be very rare and be easily fixable. If you are curious you can see that I had to add
to the flake, which is how such problems tend to be resolvable. Feel free to contact me if this happens and you don't want to burden yourself with that (I don't expect it to happen).
should you trust me?
I don't have much experience writing nix flakes.
Overal flakes are made to require little maintenance, and have no changing behavior if the lock files remain the same.
People can even invoke past versions of flakes, by supplying a git commit, in case HEAD stops working.
But, I understand if you don't want to include technology in your git repo that you yourself don't understand (if that's the case), in which case I'll just keep my fork alive (and maybe you could mention its existence in the readme, such that nix users know they might be able to use it).
