[Pandoc][1] supports conversion from Latex to e-Pub.  The chances are high that it doesn&#39;t handle *your* Latex documents completely, but it should help with the conversion process.

Pandoc has converted Tex formulae to Mathml; I don&#39;t know how good that conversion is since I haven&#39;t used it.

You could generate the TeX output in HTML, and then use the [Calibre][1] tools to convert. Basically ePub is about being a container for HTML docs (just like CHM fwiw). As an alternative, consider [BookGlutton][2] and/or LyX

I&#39;m sure all of us have seen ellipsis&#39; on Facebook statuses (or elsewhere), and clicked &quot;Show more&quot; and there are only another 2 characters or so. I&#39;d guess this is because of lazy programming, because surely there is an ideal method.

Mine counts slim characters `[iIl1]` as &quot;half characters&quot;, but this doesn&#39;t get around  ellipsis&#39; looking silly when they hide barely any characters.

Is there an ideal method? Here is mine:


    /**
     * Return a string with a maximum length of &lt;code&gt;length&lt;/code&gt; characters.
     * If there are more than &lt;code&gt;length&lt;/code&gt; characters, then string ends with an ellipsis (&quot;...&quot;).
     *
     * @param text
     * @param length
     * @return
     */
    public static String ellipsis(final String text, int length)
    {
        // The letters [iIl1] are slim enough to only count as half a character.
        length += Math.ceil(text.replaceAll(&quot;[^iIl]&quot;, &quot;&quot;).length() / 2.0d);

        if (text.length() &gt; length)
        {
            return text.substring(0, length - 3) + &quot;...&quot;;
        }

        return text;
    }

Language doesn&#39;t really matter, but tagged as Java because that&#39;s what I&#39;m mostly interested in seeing.

Ideal method to truncate a string with ellipsis

Scheme relative URLs (network-path references) are something that I&#39;ve just found out about - where you don&#39;t specify the scheme of a URL and it picks it up from the current context.

For example:
`&lt;img src=&quot;//domain.com/img.png&quot; /&gt;` will resolve to `https://domain.com/img.png` if the current scheme is HTTPS or `http://domain.com/img.png` if it is not.

This seems like a very easy way to resolve those pesky problems of calling an external script or image on an SSL page without bringing up the dreaded error that some content on a page is not secure.

The benefit seems obvious, but what I don&#39;t seem to be able to find is a huge amount of information on this and was wondering if anyone had any experience or references about scheme relative URLs (good or bad)?

Whilst I&#39;m trying to discover if there are any browsers that this causes issues with (I&#39;ve been successful with IE6-8, Chrome and Firefox), I&#39;m also interested to find out if anyone has any experience using this in different languages. For example, would it work if you were to issue a `Response.Redirect` with a scheme relative URL in ASP?

I&#39;d like to convert some university papers from LaTeX into ePub format - without using PDF as intermediate format. You know, PDF is page-oriented, while ePub is more flow-oriented.

While I found several hints, I failed to find a good &#39;standard&#39; solution.

Could someone please propose the ideal way? One which keeps mathematical formulas render beautiful?

I would like to use a lightweight markup language to take notes in my college classes. 

My editor of choice is gedit, and I found [reStructuredText Tools for Gedit](https://github.com/bittner/gedit-reST-plugin), which will run the reStructuredText processor and render the HTML in a pane in gedit. This is great, and 80% of the way there.

But for many of my classes I need to include math equations or greek characters in my notes. Although I&#39;m not very familiar with LaTeX, my understanding is that it has these capabilities. 

How can I use LaTeX in a reST document? Would the reST document need to be processed into LaTeX, then that rendered into HTML, or is there a better way? Would markdown make this easier? I can modify the gedit plugin if necessary.

Lastly, does anyone do this? Any other suggestions for taking class notes in a plain text editor?

Thanks!

I use some .sty-files that are not part of texlive and want to have them in a subdirectory of the folder with my main.tex. I used the following line to load the package:

    \usepackage{sty/prettythesis}

This works, but compiling the main.tex with xelatex and using [rubber][1] gives me a warning:

    sty/prettythesis.sty: You have requested package `sty/prettythesis&#39;,
    but the package provides `prettythesis&#39;. (page 1)

Is there a way to prevent this warning or handle this case without having to include &quot;sty\&quot; in all .sty-files&#39; \ProvidesPackage command or set the TEXINPUTS environment variable (which seems not to be possible from the main.tex itself)?

I&#39;m trying to make a presentation using the **Beamer** class. I want to show a simple list of images, one by one in one frame, just like when you use _itemize&lt;+-&gt;_.

I have no problem showing the images one-by-one, but the images shifts every time I insert a new image. How do I solve this - From my perspective there must be a simple solution, without specifying the absolute placement of the images.

I have created a class Person that looks like this: 

    public class Person
    {
        public enum GenderType
        {
            Female, 
            Male
        }

        public string Name
        {
            get; set;
        }

        public GenderType? Gender
        {
            get; set;
        }
    }

Next, I created data template that is going to present objects of type Person.  
Here&#39;s XAML code: 

    &lt;DataTemplate 
        x:Key=&quot;personTemplate&quot; 
        DataType=&quot;{x:Type model:Person}&quot;&gt;
      &lt;StackPanel&gt;
        &lt;RadioButton 
            Content=&quot;Female&quot; 
            IsChecked=&quot;{Binding Path=Gender, 
                        Converter={StaticResource genderConverter}, 
                        ConverterParameter=???}&quot;/&gt;
        &lt;RadioButton 
            Content=&quot;Male&quot; 
            IsChecked=&quot;{Binding Path=Gender, 
                        Converter={StaticResource genderConverter}, 
                        ConverterParameter=???}&quot;/&gt;
        &lt;RadioButton 
            Content=&quot;Not specified&quot; 
            IsChecked=&quot;{Binding Path=Gender, 
                        Converter={StaticResource genderConverter}, 
                        ConverterParameter=???}&quot;/&gt;
      &lt;/StackPanel&gt;
    &lt;/DataTemplate&gt;

Of course the `???`s in the code won&#39;t work :) The problem is that I want to create a `genderConverter` converter which will compare the given value, i.e. `personObject.Gender`, against the given `Person.GenderType` value provided in the parameter and return `true` if the values match. 

I don&#39;t know how to make the converter parameter pass `Person.GenderType.Female`, `Person.GenderType.Male` and `null`, for the first, second and third radio button, respectively.

 How to pass specific value to the converter parameter?

In my String, I can have an arbitrary number of words which are comma separated. I wanted each word added into an ArrayList. E.g.:

I have a problem with a p:selectOneMenu, no matter what I do I cannot get JSF to call the setter on the JPA entity. JSF validation fails with this message:

&gt; form:location: Validation Error: Value is not valid

I have this working on several other class of the same type (ie, join table classes) but cannot for the life of me get this one working.

If anyone can throw some troubleshooting/debugging tips for this sort of problem it would be greatly appreciated.

Using log statements I have verified the following:

 1. The `Conveter` is returning correct, non `null` values.
 2. I have no Bean Validation in my JPA entities.
 3. The setter `setLocation(Location location)` is never called.

This is the simplest example I can do and it simply will not work:

    &lt;h:body&gt;
        &lt;h:form id=&quot;form&quot;&gt;
            &lt;p:messages id=&quot;messages&quot; autoUpdate=&quot;true&quot; /&gt;
            &lt;p:selectOneMenu id=&quot;location&quot; value=&quot;#{locationStockList.selected.location}&quot; converter=&quot;locationConverter&quot;&gt;
                &lt;p:ajax event=&quot;change&quot; update=&quot;:form:lblLocation&quot;/&gt;
                &lt;f:selectItems value=&quot;#{locationStockList.locationSelection}&quot;/&gt;
            &lt;/p:selectOneMenu&gt;
        &lt;/h:form&gt;
    &lt;/h:body&gt;

Converter:

    @FacesConverter(forClass=Location.class, value=&quot;locationConverter&quot;)
    public class LocationConverter implements Converter, Serializable {
        private static final Logger logger = Logger.getLogger(LocationConverter.class.getName());
    
        @Override
        public Object getAsObject(FacesContext context, UIComponent component, String value) {
            if (value.isEmpty())
                return null;
            try {
                Long id = Long.parseLong(value);
                Location location = ((LocationManagedBean) context.getApplication().getELResolver().getValue(context.getELContext(), null, &quot;location&quot;)).find(id);
                logger.log(Level.SEVERE, &quot;Converted {0} to {1}&quot; , new Object[] {value, location});
                return location;
            } catch (NumberFormatException e) {
                return new Location();
            }
        }

        @Override
        public String getAsString(FacesContext context, UIComponent component, Object value) {
            if (value == null || value.toString().isEmpty() || !(value instanceof Location))
                return &quot;&quot;;
            return String.valueOf(((Location) value).getId());
        }    
    }

Console output:

    
    // Getter method
    INFO: Current value=ejb.locations.Location[id=null, name=null, latitude=0.0, longitude=0.0] 
    // Session Bean

how do you convert a string into a long.

for int you

    int i = 3423;
    String str;
    str = str.valueOf(i);

so how do you go the other way but with long.

    long lg;
    String Str = &quot;1333073704000&quot;
    lg = lg.valueOf(Str);

I&#39;m looking for a way to convert xlsx files to csv files on Linux.

I do not want to use PHP/Perl or anything like that since I&#39;m looking at processing several millions of lines, so I need something quick. I found a program on the Ubuntu repos called xls2csv but it will only convert xls (Office 2003) files (which I&#39;m currently using) but I need support for the newer Excel files.

Any ideas?
