SF-3578 Add Import Questions from Paratext notes

[josephmyers]

The notes are fetched from the Paratext local copy, and the relevant pieces are parsed. The back end replaces the tag numbers with their user-displayed text (for readability).

The front end makes this call when the user clicks the Paratext Import option in the import dialog. It first gathers the available tags and displays them as a dropdown. Once a value is chosen, it filters the notes down to the selection, and feeds them to the same display used for the Transcelerator questions.

One thing I intentionally haven't done here is to exclude resolved notes/questions, the reasons being that, if we do, there's no option for the user to bypass that and that, if they really don't want to see the item in the import list, they can just delete it in Paratext.

        @"\n\s*<",
        RegexOptions.CultureInvariant | RegexOptions.Compiled
    );

You can take advantage of .Net 8.0's Regular Expression source generator, which generates faster regex code under the hood than setting the compiled flag:

public static partial class NotesFormatter
{
    private const string NotesSchemaVersion = "1.1";

    /// <summary>
    /// The regular expression for finding whitespace before XML tags.
    /// </summary>
    /// <remarks>This is used by <see cref="ParseNotesToXElement"/>.</remarks>
    [GeneratedRegex(@"\n\s*<", RegexOptions.CultureInvariant)]
    private static partial Regex WhitespaceBeforeTagsRegex();

Code quote:

public static class NotesFormatter
{
    private const string NotesSchemaVersion = "1.1";

    /// <summary>
    /// The regular expression for finding whitespace before XML tags.
    /// </summary>
    /// <remarks>This is used by <see cref="ParseNotesToXElement"/>.</remarks>
    private static readonly Regex WhitespaceBeforeTagsRegex = new Regex(
        @"\n\s*<",
        RegexOptions.CultureInvariant | RegexOptions.Compiled
    );

    /// <param name="commentTags">The Paratext comment tag collection.</param>
    public static void ReplaceTagIdentifiersWithCommentTags(XElement notesElement, CommentTags commentTags)

This function is only used in a unit test - should it be retained?

Code quote:

        PropertyInfo[] properties = typeof(CommentTag).GetProperties(BindingFlags.Instance | BindingFlags.Public);

I'm not sure why you are iterating over every property in CommentTag? Did you need the properties marked with [XmlIgnore]? Although see also above the comment about whether we need ReplaceTagIdentifiersWithCommentTags.

Code quote:

        PropertyInfo[] properties = typeof(CommentTag).GetProperties(BindingFlags.Instance | BindingFlags.Public);

    public string Icon { get; set; } = string.Empty;
}

Up to you, but it looks like your model could take advantage of required and init, which might help keep use of your objects in future neat and tidy?

using System.Collections.Generic;

namespace SIL.XForge.Scripture.Models;

/// <summary>
/// Represents a Paratext note thread containing one or more comments for a scripture reference.
/// </summary>
public class ParatextNote
{
    public required string Id { get; init; }

    public required string VerseRef { get; init; }

    public required IReadOnlyList<ParatextNoteComment> Comments { get; init; }
}

/// <summary>
/// Represents a single comment that belongs to a Paratext note thread.
/// </summary>
public class ParatextNoteComment
{
    public required string VerseRef { get; init; }

    public required string Content { get; init; }

    public ParatextNoteTag? Tag { get; init; }
}

/// <summary>
/// Represents a Paratext comment tag that has been applied to a comment.
/// </summary>
public class ParatextNoteTag
{
    public int Id { get; init; }

    public required string Name { get; init; }

    public required string Icon { get; init; }
}

Totally optional though - just an idea I had while I was readying your code.

You'd probably also need to update the last line of NotesService.CreateNoteTag() to:

return new ParatextNoteTag { Id = tagId, Name = string.Empty, Icon = string.Empty };

Code quote:

using System;
using System.Collections.Generic;

namespace SIL.XForge.Scripture.Models;

/// <summary>
/// Represents a Paratext note thread containing one or more comments for a scripture reference.
/// </summary>
public class ParatextNote
{
    public string Id { get; set; } = string.Empty;

    public string VerseRef { get; set; } = string.Empty;

    public IReadOnlyList<ParatextNoteComment> Comments { get; set; } = Array.Empty<ParatextNoteComment>();
}

/// <summary>

public class ParatextNoteComment
{
    public string VerseRef { get; set; } = string.Empty;

    public string Content { get; set; } = string.Empty;

    public ParatextNoteTag? Tag { get; set; }

    public string Icon { get; set; } = string.Empty;

Normally we try and avoid exposing Paratext classes in interfaces, but I see it is unavoidable here.

You could perhaps move this method to IParatextDataHelper?

Code quote:

public interface INotesService

src/SIL.XForge.Scripture/Services/NotesService.cs line 14 at r3 (raw file):

public class NotesService : INotesService

I wonder whether the contents of this class should be moved to IParatextDataHelper, as it is a helper for the logic in ParatextData?

Alternatively I think naming this class to:

public class ParatextNotesService : IParatextNotesService

should help make clear what this class is doing.

Code quote:

public class NotesService : INotesService

src/SIL.XForge.Scripture/Services/NotesService.cs line 17 at r3 (raw file):

{
    public IReadOnlyList<ParatextNote> GetNotes(

Since you perform a null check, you might as well define this argument as nullable:

CommentManager? commentManager,

            if (comments.Count == 0)
                continue;

You can simplify this to:

List<ParatextNoteComment> comments =
[
    .. thread.ActiveComments.Select(comment => CreateNoteComment(comment, commentTags)),
];
if (comments.Count == 0)
    continue;

Code quote:

            IReadOnlyList<ParatextComment> activeComments = thread.ActiveComments.ToList();
            if (activeComments.Count == 0)
                continue;

            var comments = new List<ParatextNoteComment>();

            {
                comments.Add(CreateNoteComment(comment, commentTags));

This value is never null, as you coalesce it to an empty string below in CreateNoteComment.

    string GetNotes(UserSecret userSecret, string paratextId, int bookNum);
    IReadOnlyList<ParatextNote> GetNoteThreads(UserSecret userSecret, string paratextId);

You should change the signature to be nullable, as you return null in the implementation:

IReadOnlyList<ParatextNote>? GetNoteThreads(UserSecret userSecret, string paratextId)

Code quote:

We should avoid exposing PT classes in interfaces, where possible. See comment below about making this function internal and avoiding the need to expose it in this interface.

Code quote:

Why did you remove this? It will slow down syncs for projects without any questions (i.e. most projects)
