eclipse-markdown-editor-plugin's Issues

Underscore symbol breaks text

Here is example. Underscore symbol at 21:21 breaks syntax.

Widget is Disposed (Broken Preview)

Thanks for the plugin. I'm looking forward to using it.

(Markdown Text Editor Feature v0.9.0)

I get an error:

An error has occurred when activating this view
Widget is disposed

...when opening an .md file. I see the file source, but no preview.

Here is the full error:

Treat files called *.mdwn as Markdown files

Ikiwiki requires the Markdown files to be called foo.mdwn so it would be useful if this plugin could support those files too.

Errors in syntax highlighting (e.g. _)

HIghlighting breaks when we have underscore symbol inside any closed tag.
As example:
sample_text

(sample text has underscore symbol, but it not an markup symbol as it enclosed in markup symbols `` )

See on screenshot here: http://stc1.galaxyhost.org/markdown_2012-09-21_00-59_PHP.png

And some question:

Does heaers and sub headers must appeared in outline? Now I sow only sections (marked with ####) on outline tab.
How I can change the colors of mark up?

Update to markdownj-0.4

MarkdownJ 0.4 has been released.

https://github.com/myabc/markdownj/releases/tag/markdownj-0.4

And Alex Coles @myabc is doing a lot of refresh and updates.

Markdown Preview Window scrolls to top when text edited

When I make edits in the editor, the markdown HTML Preview view resets the scrollbar to the top position and I have to re-scroll down to see my changes.

Would be great if the preview tried to retain the scroll position between changes.

(awesome tool by the way)

stackoverflow Windows 10 + Eclipse Mars

Windows 10 + Eclipse Mars

I guess it is because the file opened is too large.

# comments in code blocks treated as headers by Outline view

A Markdown file containing:

# SETUP

``` sh
# generate private key
openssl genrsa -out key.pem 4096
```

results in Outline view:

SETUP
generate private key

but should only show:

SETUP

Editor does not respect Eclipse Color Theme plugin

I use a dark-colour theme from the Eclipse Color Theme plugin.
Unfortunately in the MD editor this leads to black-on-black text.
It would be great if your editor would fully support theming
based on the Eclipse Color Theme plugin @

Using the update site http://www.nodeclipse.org/updates/markdown/ in the traditional Installer gives the same messages.

Support for accentuated characters (in utf8 or iso-8859-15)

The preview pane show problems on accentuated character.

If my file is in utf8, it shows the badly interpreted é interpreted as iso-8859-1.
Even in the file in iso-8859-15, it doesn't work. It seems to only handle ASCII

Ignore Jekyll markup

In a Jekyll markdown file there is a header that defines post attributes at the top of the file, separated by ---, e.g.:


---
author: me
title: My blog post
layout: default_post

---

## My subtitle
{{ site.time | date_to_string }}

The Markdown HTML Preview and Markdown Editor should ignore content in this section (enabled by a preference?), and any content between double curly braces, {{...}} and curly-brace-percent, {%...%}. In the example above, the preview view renders the section at the top, and the editor displays the text from the underscore in default_post to the first underscore in date_to_string in italics, and doesn't render the heading in bold.

[question] Can Markdown HTML Preview show preview for HTML files?

@winterstein

As Markdown is actually superset of HTML, and Markdown HTML Preview is quick and great, can it possibly be uused to show HTML Preview while editing .html files?

(Is it possible? If possible how long could it take? What classes, lines to look at and change? ...)

Link to url fragment on same page not supported

Links to url fragments on the same page are not supported.

When I write

## Foo Heading

and refer to it using

see [above](#foo-heading)

it is valid Github Flavored Markdown because GFM automatically inserts anchors for headings (lowercase with hyphens for blanks, punctuation removed). However the editor complains "Cannot resolve element with id ''

In standard md it seems you have to provide an anchor above the heading to make this work, as shown below.

<a name="foo-heading"></a>
## Foo Heading

The latter does not work either, even if I use the id attribute.

It is particularly annoying that in Eclipse this is considered an error, so the project gets a red-cross icon, and one cannot even disable validation.

The ideal solution would be to make this work for GFM as well as plain markdown. One more argument for a GitHub flavour mode, see #41

Please confirm license

@winterstein Daniel, look at https://marketplace.eclipse.org/content/markdown-text-editor comments

What are possible licenses?

If a heading contains a colon “ : “ -- part of it isn't shown in preview

As reported by Katarína Sarnecká.

URL in code block (e.g. started with tab) gets <> too

Hi @oliviermartin This is related to #51

for a piece

http://rijksmuseum.github.io/

    https://www.rijksmuseum.nl/api/nl/collection/sk-c-5?key=fakekey&format=json

it becomes

http://rijksmuseum.github.io/

<https://www.rijksmuseum.nl/api/nl/collection/sk-c-5?key=fakekey&format=json>

The <> inside code block are actually not wanted

Update site is a 404

Using http://www.winterwell.com/software/update-site/ from the home page.

I'd build a copy myself but I can't figure out how to import the plugin into eclipse for building. Any pointers?

Offtopic conversation

@satyagraha How are you?

1.1.0 Release

@winterstein @tbrugz

update site http://dl.bintray.com/enide/Markdown/1.1.0/

marketplace http://marketplace.eclipse.org/content/markdown-text-editor

I have also added link to preferences from Preview View.

Also .classpath to plugin.

Feature description should be updated, and possibly I have not described new in 1.1.0 well

[feature request] panel buton to launch GFM Viewer View

@satyagraha maybe could hint how Markdown preview could have icon to launch GFM Viewer View (if installed)

This way, two plugins would be nicely integrated.

When opening a file ran into StackOverflow and Eclipse asking to exit (on Eclipse 4.3.0 only?)

When opening a file below ran into StackOverflow and Eclipse asking to exit

https://github.com/felixge/node-mysql/blob/master/Readme.md

(Eclipse failed to start, only renaming project folder (thus making Readme.md unavailable) )

There is definitely circular calls, with no visible class to blame (stack too long).

Formating for `code`

Discussion started in #35 & #37 for formatting code

@tbrugz says:

Unfortunately the 'header with underline' rule only seems to work when you open a .md file and not, when editting, you create a new header. If you have any tips for dealing with those IRule's I would appreciate

Link highlight is misleading

http://en.wikipedia.org and <http://en.wikipedia.org> are both highlighted with default blue. However the first case will not be converted to actual hyperlink.
This makes user to overlook potential mistakes.

Improve preview updates

Currently updates only seem to happen when I edit another file and then return to edit the first one, or when I click into the preview and then click again into the file. Also, each time an update takes place the preview scrolls up to the top.

IMO the preview should be updated when the user saves the file, at least.

Image inside a link produces invalid HTML in preview

Also, the URLs for the image source and the link are the wrong way round.

[![alt text](http://example.com/image.png)](http://example.com)

Produces:

<p><a href="http://example.com/image.png"><img src="http://example.com" alt="alt text</a>" /></p>

Should be:

    <p><a href="http://example.com"><img src="http://example.com/image.png" alt="alt text" /></a></p>

Ubuntu 16.04 + Neon.1: Markdown View remains blank

I've installed version 1.2.0.201501260515 into Neon 4.6.0 on Ubuntu 16.04 LTS.

The Markdown View (it's called that rather than Markdown HTML Preview) remains blank when opening an MD file in the Markdown Editor.

Markdown HTML preview crashes Eclipse 3.7.2 on Ubuntu

Eclipse freezes and eventually crashes when trying to open the "Markdown HTML preview" view.
Eclipse version: 3.7.2
Plugin version: 0.9.0
OS. Ubuntu 12.04 64bit
Java version: OpenJDK 1.6.0_24
Default Web Browser: Chromium (also explicitly configured as the default browser in eclipse)

Bash comments in block code section treated as header

If a markdown file has a block code section with bash code snippet, the preview and outline in the plugin treats that as a heading.

Example:

#!/bin/bash
# some comment
echo 'test'

Is rendered as:

!/bin/bash

some comment

echo 'test'

Rather than

#!/bin/bash
# some comment
echo 'test'

discussion with mylyn

I download this plugin and found it's not support table extension.
And I know Mylyn already have markdown support in it's wikiText editor plugin.
sine mylyn is a popular plugin project. can we work together to make eclipse markdown editor more powerful?

Add support for internal anchors

Markdown provides internal anchors for headings, e.g. on GitHub see https://gist.github.com/asabaylus/3071099 (and has finally fixed relative links so they work). Therefore, it would be very useful if this excellent Eclipse plugin provided equivalent functionality by generating such anchors.

You can see what GitHub does by looking at the generated page source for any .md file. I think there has been some debate about whether their implementation is exactly right (it uses the name rather than id attribute), but the principle seems pretty well-established though a bit difficult to track down in a "standard".

Mathjax support

It would be useful to support Mathjax rendering of LaTeX equations on the HTML Preview Window. For instance, the kind of Math syntax support that Mou can do.

For example, a workflow in the Editorial iPad app can do this:

<!DOCTYPE html>
<html>
<head><meta charset="utf-8"/>
<script type="text/x-mathjax-config">
  MathJax.Hub.Config({
    tex2jax: {
      inlineMath: [ ['$','$'], ["\\(","\\)"] ],
      displayMath: [ ['$$','$$'], ["\[","\]"] ]
    }
  });
</script>
<script type="text/javascript"
    src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>
</head>

<body>
    Whatever text parsed from the md file comes here.
</body>

</html>

I hacked a little workflow called Share with Math. Hence, the basic code is like the above, so it will only require a minor alteration of the header file

I was looking at the source code (specifically, pagemodel/MarkdownPage.java ) and I see you use MarkdownJ, but I don't know if it can strip Math syntax, can it?

A complementary view for GitHub Flavored Markdown

Hi, I needed a more accurate view of the resulting output when using your excellent editor on GitHub Flavored Markdown so I have created an Eclipse plugin specifically for that purpose, see https://github.com/satyagraha/gfm_viewer .

I think these two components complement each other well, and ensure very productive development when working on GitHub projects.

I want to use my custom style sheet for markdown file.

Is Eclipse Kepler supported? I use Kepler Service Release 2.

Literate Coffee & other Literate programming languages

(this is old Q and Answer, here for record and reference)

for Literate Coffee http://coffeescript.org/#literate ( was Nodeclipse/nodeclipse#26 )

We just need run docco http://jashkenas.github.io/docco/ to produce HTML
However making Coffee Editor inside Markdown Editor may be not trivial task.

Would it be simple to add docco option for HTML generation?
Could you point quickly to 1 line to change.

If you can do the conversion with a command-line call, then you can set the MarkdownEditor to use that command line.

This is probably the easiest way.

Alternatively: you can implement docco in Java. Or use an embedded javascript engine to run javascript from within Java.
With these approaches, you'd then make some minor changes to the Eclipse plugin source code.

Installation goes fine. The version of the editor is 0.2.3. It appears in the installed software list, but it's not bound to *.md files and does not appear in the Editor selection list of the "Open with..." context menu item.
