✅ My stringbuilder is skipping lines

Aside from a previous post I made: https://discord.com/channels/143867839282020352/1105409576586715166/1105409576586715166 I am trying to parse some strings lines, but the stringbuilder itself is already skipping lines and I'm not entirely sure why it skips those lines. The builder part (see the stream variable later):

StringBuilder builder = new();
using StreamReader reader = new(stream);
await reader.ReadLineAsync();

while (await reader.ReadLineAsync() is { } line && line != "---")
{
  builder.AppendLine(await reader.ReadLineAsync());
}

StringBuilder builder = new();
using StreamReader reader = new(stream);
await reader.ReadLineAsync();

while (await reader.ReadLineAsync() is { } line && line != "---")
{
  builder.AppendLine(await reader.ReadLineAsync());
}

The stream variable:

---
title: FP Config
hero_settings:
  title: my title
  subtitle: test meuk
  button_text: mail
client_header:
  title: clients
  subtitle: of us
clients: []
services_header:
  title: services
  subtitle: services
expertise_header:
  title: expertise
  subtitle: stuff
about_header:
  title: about
  subtitle: about
about:
  - leadmct: true
    mct: true
    mvp: true
    title: bryce
    subtitle: manager
    image: url.to/image/path.png
partnerships_header:
  title: partnerships
  subtitle: partners

title: FP Config
hero_settings:
  title: my title
  subtitle: test meuk
  button_text: mail
client_header:
  title: clients
  subtitle: of us
clients: []
services_header:
  title: services
  subtitle: services
expertise_header:
  title: expertise
  subtitle: stuff
about_header:
  title: about
  subtitle: about
about:
  - leadmct: true
    mct: true
    mvp: true
    title: bryce
    subtitle: manager
    image: url.to/image/path.png
partnerships_header:
  title: partnerships
  subtitle: partners
---

And what I get in the console is the following:

hero_settings:
   subtitle: test meuk
client_header:
   subtitle: of us
services_header:
   subtitle: services
   title: expertise
about_header:
   subtitle: about
   - leadmct: true
     mvp: true
     subtitle: manager
partnerships_header:
   subtitle: partners

hero_settings:
   subtitle: test meuk
client_header:
   subtitle: of us
services_header:
   subtitle: services
   title: expertise
about_header:
   subtitle: about
   - leadmct: true
     mvp: true
     subtitle: manager
partnerships_header:
   subtitle: partners

So my stringbuilder already fails 😅 I get more when I just do reader.ReadToEnd().Replace("---", "").Trim() but that will skip the body which could come after the last "---" part. So I need a way to include the body as well

So I have this .md to .yaml parser written, and a package that parses a yaml into a .NET object class, however it keeps telling me the properties cannot be found. For example, when I parse with the example class shown in https://dotnetfiddle.net/k1d6I2 my fiddle. The method I use for parsing is in there too. However, when I try to parse a markdown file:

I get the following error:

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Property 'hero_settings' not found on type 'My.Namespace.Data.FrontPageSettings'.

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Property 'hero_settings' not found on type 'My.Namespace.Data.FrontPageSettings'.

Can anyone help me out here? Or is there an easier way to parse .md files into JSON instead? (not using a console application, like this git linkhttps://github.com/markjulmar/MarkdownToJson

looks like it skips a line on every line it reads is this the whole code?

malkav•15mo ago

Yes, I think I included a fiddle Oops, no Let me make a fiddle on the whole code

i can see why

malkav•15mo ago

Why?

ero•15mo ago

lol yeah

TheRanger•15mo ago

ur calling ReadLine twice in the while loop

ero•15mo ago

you AppendLine await reader.ReadLineAsync() instead of line

TheRanger•15mo ago

and you never used the line variable change to

        while (await reader.ReadLineAsync() is { } line && line != "---")
        {
            builder.AppendLine(line);
        }

        while (await reader.ReadLineAsync() is { } line && line != "---")
        {
            builder.AppendLine(line);
        }
