I've fixed this issue. Now i don't set anything to the tag SPAN and others TAGs like this one. Thanks for your advice.

Resolution

Jortx,

We wrap our PRE tags with a div like this:

[HTML] - Copy Code
<div class="ForumPostCode"><pre>...</pre></div>

Then here is our CSS for that:

Copy Code
.ForumPostCode { margin: 0.5em 0px 0.5em 15px; width: 650px; overflow: auto; }

But we use fixed width. You'd have to consult some other CSS forums for more help with overflow if you are having trouble since that is outside the scope of this control.

Re: Setting the font

Actipro Software Support — Wed, 27 Jan 2010 15:34:25 GMT

Resolution

Well that is how CSS works. We use SPANs to set font attributes so if you apply a global font-family to SPAN tags then it will be applied to anything we do. I would never recommend setting a global font-family/size on a SPAN tag in CSS. You should set the CSS font properties on things like BODY, TD, etc. instead, or SPANs but only ones with CSS class or id's.

Another thing is that our Style tags in the language definition files do let you set FontFamilyName and FontSize attributes there, which would likely override your CSS settings as-is.

Ok.
I've tried to set a fix width to the PRE, and then it works. I can see the scroll bars.
So, without setting a fix with, is there a way to show the scroll bars when the content is biger?
Thanks for the replies.

Hi,
I'm trying to write a few chars in the same line, inside the control, and the result is the PRE gets bigger than the screen, in place of show the scroll bars o hide the overflow.
I've tried to set de overflow: scroll and overflow: hidden , in the CSS class used by the PRE control, unsuccessfully.
Maybe there is another way to change it... I hope it.
Thanks a lot!

YES! Is it!
If you set a default font to the SPAN html control in yous CSS style sheet, then you are not able to change the CodeHighlighter Control Font.
Maybe should be a way to set the font in the control regardless of the default font.
Cheers!

Thanks a lot.
You are right, it should be something like this, but i'm trying to explain that is not easy to change by the "logical" ways.
No change with this:

[HTML] - Copy Code
<pre style="font-family: Arial;"><CH:CodeHighlighter runat="server" ID="CssCodeHighlighter" LanguageKey="CSS">...

No change with this:

[HTML] - Copy Code
<DIV style="font-family: Arial;"><pre><CH:CodeHighlighter runat="server" ID="CssCodeHighlighter" LanguageKey="CSS">...

This throw an exception:

[HTML] - Copy Code
<pre><CH:CodeHighlighter runat="server" ID="CssCodeHighlighter" LanguageKey="CSS" style="font-family: Courier-New">...

¿Am I the extrange case? ¿Nobody has had this problem?
Great control, but this is a problem if is not easy to change the font...

Maybe this CSS rule in my site has some incompatibility with your control:

[CSS] - Copy Code
span, td, .TextoNormal {
font-family: Verdana, Arial;
font-size: 14px;
color: #bbbbbb;
}

I allways see the same font, "Verdana 14px", while making the changes I have said.

Thanks for your response!

I was able to change it by putting a CSS style on the PRE that should surround the control:

Question

Product Version: CodeHighlighter v4.0.58

Hi!
I have a very simple question... ¿How to change the font used in the control?
Is very nice that the font used, be the default font, but i need to change the font, and is being very difficult to change it!!
Nothing changes when I put all the control inside this TAGs: <font face="Courier New"> and </font>
I've tried with DIVs, and nothing...
I don't find any property to change in the control properties...
Just find, in the documentation, something like this XML syntax (to find in the documentation search "Style Tag"):

[XML] - Copy Code
<SyntaxLanguage Key="C#" LanguageDefinitionVersion="4.0">
    <!-- Highlighting Styles -->    
    <Styles>
        <!-- Optional Styles to Override Built-In Styles -->
        <Style Key="BracketHighlightingStyle" Name="Bracket Highlighted Text" BackColor="Silver" />
        <Style Key="CollapsibleTextStyle" Name="Collapsible Text" ForeColor="Gray" BorderStyle="Solid" BorderCornerStyle="SinglePixelRounded" />
[...]

I don't know how to use it.
¿Can anybody tell me how to set the font i like, in the control?
Thanks a lot!

Well it needs the dll files marked as redistributable in the Readme to be placed in your ASP.NET site's bin folder. Then you'd also need to set up your web.config like in the sample.

Sorry but not right now since all CodeHighlighter outputs is raw HTML code.

Hi Again

After deeper investigation i found that it will be more useful to have client side functions for highlighting lines or pieces of code.

It is possible?

Thanks,

Re: Modifying the generated HTML

More Information

Not sure yet but our SyntaxEditor for WPF product is under heavy development now and that means that work is progressing on the improved document/parsing library that will eventually be used for CodeHighlighter. Still it may be several months before a new CodeHighlighter version for the improved framework is ready.

Ahh I see. Thanks for the suggestion, I'll mark it down.

So the next major version of CodeHighlighter will be using this updated assembly and we hope to add support for things like span indicators at that time.

I'll be waiting Approximately when?

Yes, I can limit code passed to Highlighter but there will be problem with opened comments

[C#] - Copy Code
/* comment comment
   comment comment
   comment comment
   comment comment
*/
public class SomeClass
{
  public int SomeMethod();
}

Drop first line (limit range) and we have

[C#] - Copy Code
   comment comment
   comment comment
   comment comment
*/
public class SomeClass
{
  public int SomeMethod();
}

So range of text can be catched correctly only by CodeHighlighter.

Hi Svyatoslav,

Thanks for the suggestions. No updates yet, however right now we are working on the next major version of our document/parsing engine as we develop our WPF version of SyntaxEditor. We are making a separate assembly that only does document/parsing functionality. So the next major version of CodeHighlighter will be using this updated assembly and we hope to add support for things like span indicators at that time.

Re: Modifying the generated HTML

Svyatoslav Danyliv — Sun, 10 Aug 2008 00:03:27 GMT

Suggestion

Hi All,

Is tehere some news for this feature?
I need to highlight some lines of code with different background and i see that i will need additional HTML parsing. It's possible but i'm looking for more accurate solution.

I suggest the following. I can add to original source file a special tags. For examle:

[C#] - Copy Code
public 
[CodeHighliter, Background=yellow, VirtualSpace=1, Bookmark=#BookmarkName, HTML="maybe some open html tags"]class Test {}[/CodeHighliter, HTML="maybe some close html tags"]
  void [CodeHighliter, Bacground=green]SomeFunction[/CodeHighliter](int someParam)
  {
  }

Background tells that background color should be changed to yellow,
VirtualSpace tells that line should be colored fully including virtual space.
Bookmark - it will be nice if CodeHighlighter will put bookmarks for needful lines of code for navigation
HTML - maybe for placing some marks to correct html after generating.

I assume that this needs some preprocessing and may be out of scope of SyntaxtEdit engine. But who know maybe it's not too hard to implement. It will be very appresiated!

I'm trying to finish our internal tool for analysing Crash Call Stack information, and will be good to have engine that can highlight problematic lines in code.
Also preprocessing can be replaced by additional API before generation. IOW acceptable is all, that can tell to CodeHighlighter how highlighting should be changed

BTW, Thanks for great product!

P.S. What about limiting code lines? I found post with this suggestion but i think this still in TODO also?

TIA,
Svyatoslav

Re: Indentation and code formatting

Actipro Software Support — Tue, 27 May 2008 07:25:03 GMT

Only if the language implementation supports formatting. Our Web Languages Add-on's XML language does support document formatting but that's the only one we currently provide that does have built-in code formatting support at this time.

Indentation and code formatting

Nigel Ellis — Mon, 26 May 2008 19:12:38 GMT

Question

Product Version: CodeHighlighter v4.0.51

Hi,

I'm using the code formatting library in a managed code application (Office Addin). The formatting is working fine (syntax coloring). I was wondering if there was anyway to have the engine handle reformatting indentation.

For example:
foreach (int i in method()) { Console.WriteLine(i); }

==>
...foreach (int i in method())
...{
......Console.WriteLine(i);
...}

Thanks,
Nigel.

Re: Nesting in a ListView control does not display code

Hi,
The problem is solved. This was my code:

[HTML] - Copy Code

<cc1:CodeHighlighter ID="codeHighlighter" runat="server" LanguageKey='<%# Eval("Language") %>'>
     <%# Eval("Body") %>
</cc1:CodeHighlighter>

The solution was to set the text using the property instead:

[HTML] - Copy Code

<cc1:CodeHighlighter ID="codeHighlighter" runat="server" LanguageKey='<%# Eval("Language") %>' Text='<%# Eval("Body") %>'/>

Setting the Text using the first method doesn't work for data bound values.
I don't know if this is a bug or not, but it works for me now.

Thank you for offering both great tools and great support :-)

Re: Use CodeHighlighter directly in code

Actipro Software Support — Fri, 11 Apr 2008 06:50:09 GMT

Resolution

Looks like the Troubleshooting topic is only in the SyntaxEditor control help. Here is the part that is is referring to:

If you copy one of our dynamic language definition samples from the sample project for use in your project, you may encounter this error message when you load the language in your application:

An error occurred while loading the DynamicSyntaxLanguage '{Unknown}': The syntax language type 'TestApplication.[LanguageName]SyntaxLanguage, TestApplication' could not be loaded. The problem occurred near line 1, position 2 in Unknown Stream

What is happening here is that the root SyntaxLanguage tag in the XML language definition is specifying which code-behind class to use for outlining and other features. The XML files are configured to work with our TestApplication assembly. However it's a quick change to make a copy of them work with your project.

These two topics describe how to use the SyntaxLanguage tag's SyntaxLanguageTypeName attribute and what value you need to set to get it working with your project:

[edit - Look at this topic in the CH documentation]: Dynamic Languages Guide / XML Definition Specification / SyntaxLanguage Tag

Re: Use CodeHighlighter directly in code

Golo Roden — Fri, 11 Apr 2008 06:36:36 GMT

Question

Hi,

thanks for your reply.

For the most languages I have gotten it to work now using the following code:

[C#] - Copy Code
CodeHighlighterEngine engine = new CodeHighlighterEngine();
SyntaxLanguage language = DynamicSyntaxLanguage.LoadFromXml(@"ActiproSoftware.PHP.xml", 0);

string text = "using System;\n\npublic class Program\n{\n}";
text = engine.GenerateHtmlInline(Guid.NewGuid().ToString(), text, language);

Anyway, there are languages where this approach does not work, e.g. C#. When trying to load the data from the XML file I always get an exception telling me:

{"An error occurred while loading the DynamicSyntaxLanguage '{Unknown}':\r\nThe syntax language type 'CodeHighlighterTest.CSharpDynamicSyntaxLanguage, CodeHighlighterTest' could not be loaded. Please see the 'Troubleshooting' topic in the documentation for details on how to resolve this error.\r\nThe problem occurred near line 1, position 2\r\nin Unknown Stream."}

What is wrong with my code?

Thanks in advance,

Golo

Re: Use CodeHighlighter directly in code

1) You can create a CodeHighlighterEngine object and call its GenerateHtmlInline method.

Dynamic languages can be loaded from the DynamicSyntaxLanguage.LoadFromXml static method. It's on DynamicSyntaxLanguage, not SyntaxLanguage.

2) Yes unless you embed them in an assembly as a manifesst resource and load them from there.

Question

Product Version: CodeHighlighter v4.0.51

Hi there,

I have got some questions regarding your CodeHighlighter component.

1. Do you have a working (!) example on how to use CodeHighlighter directly in code? In all examples I could find there is a method LoadFromXml on SyntaxLanguage type, but actually this method does not exist :-(

2. Do I have to deploy the .xml files, or is there a way to deploy only the .dll's?

Have a nice day,
