noahric / markdownmode Goto Github PK

When I create a new txt file and append the md extension, the markdown preview window work well. but when I close the file, and
open it again, the editor couldn't display the markdown syntax.

I used visual studio 2010,and the latest markdown mode.

Thanks for your help.

This extension in VS pro 2015 is causing an MEF component cache exception on startup when opening a solution of 20 projects, none of which have markdown. Information on crash and configuration is below. As it stands, if the extension is enabled it causes the exception every other startup as the ones where it does not crash are on a freshly built cache. Disabling the extension resolves the issue. IIRC this was also an issue on update 2.

The exception entry from the activity log is:

Here's a picture to illustrate the problems:

• Sometimes the language-name is green, sometimes black (should always be black)
• Sometimes some non-indented code lines are green, sometimes black (should always be green)
• Sometimes the closing-triple-blacktick is mixed colors (should always be black)
• Sometimes the paragraph following the closing-triple-backtick has the wrong colors (I'm not sure what's going on here)

For example, a <link.../> tag in line 1 of foo.md causes VS2010 to treat the file as xml, ignoring the .md extension.

The project description and README suggest that this extension is only for VS2010, however it works well in VS2013 (and possibly VS2012 as well).

I'm not sure what is happening, but I am unable to remove the preview window. The "Show Preview Window" opens/closes a second preview window and there seems to be a default preview window that is unclosable.

Screenshot of the default (there is no close button): http://screencast.com/t/ruwZjvVK

Screenshot of the two open. I can close the right most one: http://screencast.com/t/ohjAoqmR3Po

Text like the following renders correctly in the preview, but wrong in the editor:

 - A list item

    Indented text within the list.

In the editor, it appears as blockquote. The problem is that within a list indented text should only be considered a blockquote if it is indented twice.

original file:
01-Introduction.zip

The encoding seems off. When using characters like å, the preview window shows it as Ã¥. When commited to BitBucket it shows correctly on their site.

It would be highly desirable if I could set a default stylesheet for my Markdown, or even reference one.

The preview windows is showing wrong characters.

Exemple:

Implementação de classes e métodos de infraestrturua, tais como classes de envio de e-mail, sms, webservices entre outros.

For example, the markdown editor is completely unusable for the following file:
https://github.com/openstacknetsdk/openstack.net/wiki/Feature-Support

This appears to be caused by the regular expressions used by the editor features, which are more complicated than the expressions used by MarkdownSharp due to alterations required to support processing without first normalizing newline characters and expanding hard tabs to the correct number of spaces.

I'm currently working on a solution (80% done). Instead of using a string to represent the text in MarkdownParser, I used ITextBufferFactoryService to create a new ITextBuffer. This allows modifying the buffer, following by using ITrackingSpan to map spans of modified text back to their original locations in the source text (i.e. we can now normalize the file prior to parsing).

With a few enhancements, MM could easily be used as a documentation browser for our source code.

The three enhancements I'm thinking of:

• Custom stylesheet/layout, on a per-solution basis. Just a way to make the preview prettier and add boilerplate HTML
• Handle relative links correctly. In my Markdown, if I have a link to test.md it should tell VS to open that file if it exists. This will make it MM acts as a browser almost within VS. It will open extra tabs, but then you can use VS' built in back/forward to navigate between docs.
• Switch to using Pandoc to generate HTML

Markdown# is cool, but I've had better luck packaging Pandoc.exe and executing it against markdown files to generate HTML. Here's a sample in C#:

// Process to output dir
var pandocStart = new ProcessStartInfo();
pandocStart.FileName = "pandoc";

// Standalone HTML generation using a template file
// Use Github Markdown processing!
pandocStart.Arguments = "pandoc -r markdown_github --highlight-style=kate --template=template.html --toc";
pandocStart.RedirectStandardError = true;
pandocStart.RedirectStandardOutput = true;
pandocStart.RedirectStandardInput = true;
pandocStart.UseShellExecute = false;
pandocStart.CreateNoWindow = true;
pandocStart.WindowStyle = ProcessWindowStyle.Hidden;

using (var pandoc = Process.Start(pandocStart))
{
    var rawText = File.ReadToEnd(markdownFile);
    string html;

    using (StreamWriter writer = pandoc.StandardInput)
    {
        await writer.WriteAsync(rawText);
    }

    using (StreamReader reader = pandoc.StandardOutput)
    {
        html = await reader.ReadToEndAsync();
    }

    using (StreamReader reader = pandoc.StandardError)
    {
        var error = await reader.ReadToEndAsync();

        if (!String.IsNullOrEmpty(error))
        {
            throw new Exception(error);
        }
    }

    // Do something with the HTML generated by Pandoc
}

I think this is better than using M# because it supports all sorts of extensions including tables, fenced code blocks, auto ID generation, and more (documented by Pandoc). Even cooler, it supports Pandoc title blocks or MultiMarkdown title blocks.

Doesnt support!

The preview window supports indented code blocks, but not those escaped with triple-backticks:

```csharp
var foo = Foo();
foo.Bar();
```

Such code is styled with a monospace font, but it wraps onto one line instead of honouring line breaks. If the output is styled using CSS, then the white-space: pre-wrap rule should be applied.

I noticed that German umlauts don't get rendered correctly in the preview pane.
"Copy HTML to clipboard" does not have that issue.

(Funny enough, the original markdown implementation in Perl seems to have a similar problem.)

Sample (download file):

# Überschrift 1
Die süße Hündin läuft in die Höhle des Bären, der sie zum 
Teekränzchen eingeladen hat, da sie seine drei schönen 
Krönchen gerettet hat, was sie wie folgt angestellt hat: 
Sie läuft über einen Fluss und tötet alle grünen Frösche, 
die über die Krönchen wachen, so hat sie diese schönen 
Krönchen gerettet.

Screenshot:

not sure if this is part of the official markdown spec, but on github you can make headlines by underlining them with "=" (for h1) and "-" (for h2). I think having support for that would be extremely neat :)

The font used in the editor for blocks is Courier New, and it doesn't appear that this can be changed. Consolas would be a better default, although if it would be user-selectable, I think I'd change it to something like Verdana to improve typographic readibility and conserve real estate, but still be different than normal text (for an inline block, there is rarely any need for the alignment benefits of a non-proportional font).

Currently it's missing on NuGet and/because the vsix cannot be installed on VS 2015

After the extension is installed, in VS2012, from the Extension and Updates window, under the Installed section of the treeportion (not the the Online section), the More Information link points to a blog that doesn't directly deal with the extension. A link to either the GitHub or VS gallery page would be better (those two can link to each other).

If the user adds or removes a character in the input, only the current line's syntax highlighting is updated. If the change affected multiple lines, the highlighting for those lines will be out-of-date until changes are made to those lines or the file is closed and reopened.

Environment:

Microsoft Visual Studio Ultimate 2012
Version 11.0.60315.01 Update 2
Microsoft .NET Framework
Version 4.5.50709

Markdown Mode version 2.4

If I have a markdown document with links to http or https pages in it, when I click a link in the markdown preview window (in order to check the link goes to the correct destination) I cannot then go back to the original markdown preview.

With the preview window in focus:

• Alt + left arrow does not work;
• backspace does not do anything;
• neither does Ctrl+- or the back button on the Visual Studio toolbar (I'm not sure these two should, as they are usually used to go to your last code location, but I thought I would try them anyway);
• closing and re-opening the preview window does not restore the original preview.

The only way to restore the preview is to close the whole markdown document, and then the preview window will re-sync with the document.

First, let me say I absolutely love this extension!

When I include javascript or html source code in my markdown file, they are both executed. That code should be encoded when between the markers. Not encoding javascript results in constant error messages while editing markdown files.
