+* `System.Text.Json.Nodes` is an unfathomably weird API which simply requires us to make educated guesses about whether a user-provided type is supposed to be nullable, despite this being irrelevant to the operation of `System.Text.Json`;
+* Some types (like `Uri` and `String`) have `ToString` methods which can't return `null`, but in general `Object.ToString` can of course return `null`, and as far as I can tell there is simply no way to know from the source alone whether a given type will have a nullable `ToString`.
+
+# WoofWare.Myriad.Plugins 6.0.1
+
+The `ArgParser` generator's type signatures have changed.
+The `parse'` method no longer takes `getEnvironmentVariable : string -> string`; it's now `getEnvironmentVariable : string -> string option`.
+This is to permit satisfying the `<Nullable>enable</Nullable>` compiler setting.
+If you're calling `parse'`, give it `Environment.GetEnvironmentVariable >> Option.ofObj` instead.
+
+# WoofWare.Myriad.Plugins 5.0.1
+
+We now enforce non-nullability on more types during JSON parse.
+We have always expected you to consume nullable types wrapped in an `option`, but now we enforce this in more cases by throwing `ArgumentNullException`.
+
+# WoofWare.Myriad.Plugins 3.0.1
+
+Semantics of `HttpClient`'s URI component composition changed:
+we now implicitly insert `/` characters after `[<BaseAddress>]` and `[<BasePath>]`, so that URI composition doesn't silently drop the last component if you didn't put a slash there.
+
+# WoofWare.Myriad.Plugins 2.3.9
+
+`JsonParse` and `JsonSerialize` now interpret `[<JsonExtensionData>]`, which must be on a `Dictionary<string, _>`; this collects any extra components that were present on the JSON object.
+
+# WoofWare.Myriad.Plugins 2.2.1, WoofWare.Myriad.Plugins.Attributes 3.2.1
+
+New generator: `ArgParser`, a basic reflection-free argument parser.
+
+# WoofWare.Myriad.Plugins 2.1.45, WoofWare.Myriad.Plugins.Attributes 3.1.7
+
+The NuGet packages are now attested to through [GitHub Attestations](https://github.blog/2024-05-02-introducing-artifact-attestations-now-in-public-beta/).
+You can run `gh attestation verify ~/.nuget/packages/woofware.myriad.plugins/2.1.45/woofware.myriad.plugins.2.1.45.nupkg -o Smaug123`, for example, to verify with GitHub that the GitHub Actions pipeline on this repository produced a nupkg file with the same hash as the one you were served from NuGet.
+
+# WoofWare.Myriad.Plugins 2.1.33
+
+`JsonParse` can now deserialize the discriminated unions which `JsonSerialize` wrote out.
+
+# WoofWare.Myriad.Plugins 2.1.32, WoofWare.Myriad.Plugins.Attributes 3.1.4
+
+`JsonSerialize` can now serialize many discriminated unions.
+(This operation is inherently opinionated, because JSON does not model discriminated unions.)
+
+# WoofWare.Myriad.Plugins 2.1.20, WoofWare.Myriad.Plugins.Attributes 3.0.1
+
+We now bundle copies of the RestEase attributes in `WoofWare.Myriad.Plugins.Attributes`, in case you don't want to take a dependency on RestEase.
+
+# WoofWare.Myriad.Plugins 2.1.15
+
+The `GenerateMock` generator now permits a limited amount of inheritance in the record we're mocking out (specifically, `IDisposable`).
+
+# WoofWare.Myriad.Plugins 2.1.8
+
+No change to the packages, but this is when we started creating and tagging GitHub releases, which are a better source of truth than this file.
+
+# WoofWare.Myriad.Plugins 2.0
 
 This transition split the attributes (e.g. `[<JsonParseAttribute>]`) into their own assembly, WoofWare.Myriad.Plugins.Attributes.
 The new assembly has minimal dependencies, so you may safely use it from your own code.

 If you would like to ensure that your particular use-case remains unbroken, please do contribute tests to this repository.
 The `ConsumePlugin` assembly contains a number of invocations of these source generators,
 so you just need to add copies of your types to that assembly to ensure that I will at least notice if I break the build;
 and if you add tests to `WoofWare.Myriad.Plugins.Test` then I will also notice if I break the runtime semantics of the generated code.

@@ -150,6 +152,160 @@ The same limitations generally apply to `JsonSerialize` as do to `JsonParse`.
 
 For an example of using both `JsonParse` and `JsonSerialize` together with complex types, see [the type definitions](./ConsumePlugin/SerializationAndDeserialization.fs) and [tests](./WoofWare.Myriad.Plugins.Test/TestJsonSerialize/TestJsonSerde.fs).
 
+## `ArgParser`
+
+Takes a record like this:
+
+```fsharp
+type DryRunMode =
+    | [<ArgumentFlag true> Dry
+    | [<ArgumentFlag false> Wet
+
+[<ArgParser>]
+type Foo =
+    {
+        [<ArgumentHelpText "Enable the frobnicator">]
+        SomeFlag : bool
+        A : int option
+        [<ArgumentDefaultFunction>]
+        B : Choice<int, int>
+        [<ArgumentDefaultEnvironmentVariable "MY_ENV_VAR">]
+        BWithEnv : Choice<int, int>
+        [<ArgumentDefaultFunction>]
+        DryRun : DryRunMode
+        [<ArgumentLongForm "longer-form-replaces-c">]
+        C : float list
+        // optionally:
+        [<PositionalArgs>]
+        Rest : string list // or e.g. `int list` if you want them parsed into a type too
+    }
+    static member DefaultB () = 4
+    static member DefaultDryRun () = DryRunMode.Wet
+```
+
+and stamps out a basic `parse` method of this signature:
+
+```fsharp
+[<RequireQualifiedAccess>]
+module Foo =
+    // in case you want to test it
+    let parse' (getEnvVar : string -> string) (args : string list) : Foo = ...
+    // the one we expect you actually want to use
+    let parse (args : string list) : Foo = ...
+```
+
+Default arguments are handled as `Choice<'a, 'a>`:
+you get a `Choice1Of2` if the user provided the input, or a `Choice2Of2` if the parser filled in your specified default value.
+
+You can control `TimeSpan` and friends with the `[<InvariantCulture>]` and `[<ParseExact @"hh\:mm\:ss">]` attributes.
+
+You can generate extension methods for the type, instead of a module with the type's name, using `[<ArgParser (* isExtensionMethod = *) true>]`.
+
+If `--help` appears in a position where the parser is expecting a key (e.g. in the first position, or after a `--foo=bar`), the parser fails with help text.
+The parser also makes a limited effort to supply help text when encountering an invalid parse.
+
+### What's the point?
+
+I got fed up of waiting for us to find time to rewrite the in-house one at work.
+That one has a bunch of nice compositional properties, which my version lacks:
+I can basically only deal with primitive types, and e.g. you can't stack records and discriminated unions inside each other.
+
+But I *do* want an F#-native argument parser suitable for AOT-compilation.
+
+Why not [Argu](https://fsprojects.github.io/Argu/)?
+Answer: I got annoyed with having to construct my records by hand even after Argu returned and said the parsing was all "done".
+
+### Limitations
+
+This is very bare-bones, but do raise GitHub issues if you like (or if you find cases where the parser does the wrong thing).
+
+* Help is signalled by throwing an exception, so you'll get an unsightly stack trace and a nonzero exit code.
+* Help doesn't take into account any arguments the user has entered. Ideally you'd get contextual information like an identification of which args the user has supplied at the point where the parse failed or help was requested.
+* I don't handle very many types, and in particular a real arg parser would handle DUs and records with nesting.
+* I don't try very hard to find a valid parse. It may well be possible to find a case where I fail to parse despite there existing a valid parse.
+* There's no subcommand support (you'll have to do that yourself).
+
+It should work fine if you just want to compose a few primitive types, though.
+
+## `SwaggerClient`
+
+Takes a JSON-schema definition of a [Swagger API](https://swagger.io/), and stamps out a client like this:
+
+```fsharp
+/// A type which was defined in the Swagger spec
+[<JsonParse true ; JsonSerialize true>]
+type SwaggerType1 =
+    {
+        [<System.Text.Json.Serialization.JsonExtensionData>]
+        AdditionalProperties : System.Collections.Generic.Dictionary<string, System.Text.Json.Nodes.JsonNode>
+        Message : string
+    }
+
+/// Documentation from the Swagger spec
+[<HttpClient false ; RestEase.BasePath "/api/v1">]
+type IGitea =
+    /// Returns the Person actor for a user
+    [<RestEase.Get "/activitypub/user/{username}">]
+    abstract ActivitypubPerson :
+        [<RestEase.Path "username">] username : string * ?ct : System.Threading.CancellationToken ->
+            ActivityPub System.Threading.Tasks.Task
+```
+
+Notice that we automatically decorate the type with our `[<HttpClient>]` attribute, so if you choose to do so, you can chain another Myriad generated file off this one and you'll get a RestEase-style client stamped out.
+(See below, searching on the string `"Generated2SwaggerGitea.fs"`, for an example.)
+
+You don't need to `Content Include` or `EmbeddedResource Include` the JSON schema.
+`None Include` will do; we only need the source to be available at build time.
+
+You *do* need to include the following configuration:
+
+```xml
+<Compile Include="GeneratedClient.fs">
+  <!-- This bit is normal: -->
+  <MyriadFile>swagger.json</MyriadFile>
+  <!-- This bit is new and required! -->
+  <MyriadParams>
+    <ClassName>GiteaClient</ClassName>
+    <!-- Optionally: -->
+    <GenerateMock>true</GenerateMock>
+  </MyriadParams>
+</Compile>
+```
+
+The `<ClassName />` key tells us what to name the resulting interface (it gets an `I` prepended for you).
+You can optionally also set `<GenerateMockVisibility>v</GenerateMockVisibility>` to add the `[<GenerateMock>]` attribute to the type
+(where `v` should be `internal` or `public`, indicating "resulting mock type is internal" vs "is public"),
+so that the following manoeuvre will result in a generated mock:
+
+```xml
+<None Include="swagger-gitea.json" />
+<Compile Include="GeneratedSwaggerGitea.fs">
+  <MyriadFile>swagger-gitea.json</MyriadFile>
+  <MyriadParams>
+    <GenerateMockVisibility>public</GenerateMockVisibility>
+    <ClassName>Gitea</ClassName>
+  </MyriadParams>
+</Compile>
+<Compile Include="Generated2SwaggerGitea.fs">
+  <MyriadFile>GeneratedSwaggerGitea.fs</MyriadFile>
+</Compile>
+```
+
+(Note that you do have to create the `GeneratedSwaggerGitea.fs` file manually before code generation happens. Myriad will throw if that file isn't there, because `Generated2SwaggerGitea.fs` depends on it so Myriad wants to compute its hash. Just make an empty file.)
+
+### What's the point?
+
+[`SwaggerProvider`](https://github.com/fsprojects/SwaggerProvider) is *absolutely magical*, but it's kind of witchcraft.
+I fear no man, but that thing… it scares me.
+
+Also, builds using `SwaggerProvider` appear to be inherently nondeterministic, even if the data source doesn't change.
+
+## Limitations
+
+Swagger API specs appear to be pretty cowboy in the wild.
+I try to cope with invalid schemas I have seen, but I can't guarantee I do so correctly.
+Definitely do perform integration tests and let me know of weird specs you encounter, and bits of the (very extensive) Swagger spec I have omitted!
+

 </ItemGroup>
 ```
 
+## Alternative use without the attributes
+
+You can avoid taking a reference on the `WoofWare.Myriad.Plugins.Attributes` assembly, instead putting all the configuration into the project file.
+This is implemented for everything except the SwaggerClientGenerator.
+
+```xml
+<Project>
+  <ItemGroup>
+    <Compile Include="Client.fs" />

+    <PackageReference Include="Myriad.Sdk" Version="0.8.3" PrivateAssets="all" />
+  </ItemGroup>
+</Project>
+```
+
+That is, you specify a `!`-delimited list of the attributes you *would* apply to the type.
+Supply "arguments" to the attribute name in the project file as you would to the attribute itself.
+
+(Yes, this is indeed incredibly cumbersome, and you're not interested in the reasons it's all so mad!
+I'm hopefully going to get round to writing a more powerful source generation system which won't have these limitations.)

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
