markdown or markup to powerpoint? - powerpoint

I need to maintain some slides in both latex beamer and in powerpoint. (This is to make slides available for instructors elsewhere, too, 90% of which do not know how to use latex and are unwilling to learn it. and I am a latex guy on linux.)
I have tried the route via Libreoffice (and opendocument), but this did not come out well. right now, the best method that I have found is to author pdf in beamer, then run it through a nuance OCR program to get MS Word...and not even go all the way to Powerpoint (which is where I really need to be).
If I only had a markup language that produced nice Powerpoint, I could probably code a perl translator from markdown to this intermediate markup language. (going from markdown to latex beamer is relatively easy.)
I don't think this exists, but hope springs eternal. after all, it is almost 2014 now. does anyone know of a solution?

One solution is to use odpdown: It converts markdown to the OpenOffice Presenter format, which can be imported into PowerPoint.
It is not yet complete, i.e. table support is missing and possibly not running on certain Windows setups, but nevertheless it could be a start. Possibly, you have Linux running, where it seems to work.

Steve Rindsberg's answer in the comments works on PP 2007 works! Let me repeat it here:
I suspect that PowerPoint is the likeliest solution. ;-) But what sort
of slides are you creating? If they're simple heading and bullet point
slides, all you need to produce is a simple text file. Any text that
starts in the left column will be the heading of a new slide. Indent
one tab and it becomes a first-level bullet point under the current
heading; indent two tabs, it becomes a second level bullet point and
so on. Simply use File | Open on the text file to pull it into PPT.
Steve: Is this all that PP converts? Or is there a reference of other "sneaky" markup that PP knows about?
(pandoc: unfortunately, the conversion from libreoffice to powerpoint is pretty poor when I tried it last. I also tried to save and understand the powerpoint xml format, but that was REAL bad.)

The easiest way to handle this is to work with:
RStudio (and R if not already installed)
RMarkdown
Pandoc 2.0.5 (minimum)
Install those 3 (or 4) items, then read: https://bookdown.org/yihui/rmarkdown/powerpoint-presentation.html
The installation time is worth the time saved copy-pasting everything from scratch.

I also am a Linux guy and I also use LateX engines to create nice documents. Based on my experience, here's what you should do :
Stop writing directly in LaTeX and start using org-mode to write documents instead (I spent years writing in LaTeX and now it's over (except when I use modernv package))
Org supports latex math formulas and .org files are easily exported in .tex files
Org can also be easily exported in markdown
Once you have your markdown, there are several tools that will allow you to create a PowerPoint. Two of them are pandoc and md2pptx

exist-db how to access a pdf

I am sure it is very simple ... I just cannot get my head around this...
the exist-db Documentation is a bit fuzzy on content extraction...
http://exist-db.org/exist/apps/doc/contentextraction.
I have a pdf-file, containing of about 162 high-res images (the pdf is quite big ...) and I do not know how to access any of the that are presumably created ...
please do not destroy me! I am just starting to build a database (for an Edition at Uni)I'd love to have a facsimile edition (so one Tab with the image-file and one tab with the transcribed texts)
I aim at doing something similar to what Heidelberg Universitdy did with the "Welsche Gast Digital" http://digi.ub.uni-heidelberg.de/diglit/cpg389/0190/image
(the choosen image is just an example! )
This pic
When clicking on faksimile the Scan opens and when clicking on Transkription the transcribed texts open!
I am quite new to Xquery, Xpath and most X-related stuff. I have a "working design" put together in exist-db and am looking at TEI for marking up the transcritpion etc, I fear I'll have to spend quite some time on this issue ...
(it is not about doing my job for me, it's just about pointing me in the right direction)
I m afraid the short answer is simply don't.
Storing a pdf in your db, and then trying to extract images from it, is kind of a recipe for disaster. Instead you should use the source images (not necessarily extracted from the pdf), and store these individually in a collection (e.g. resources/img). Those image files are then the binary resources that the documentation is actually talking about.
You might want to take a look at tei-publisher for creating digital edition in exist, especially this demo app for how to present high-res facsimiles with transcribed portions of text. I m afraid its all a bit more involved then just opening a pdf in a browser, but so is the Welsche Gast Digital

Generating Powerpoint or Keynote from XML (or via a Ruby gem?)

I'm looking for a nice way to generate either a Keynote file from XML or a Powerpoint file that I can then import to Keynote. Basically, I'm looking for a simple human-writable markup format (for easy scripting) that can be exported into slides.
I volunteer with a local nonprofit, where anything remotely technical falls to me. On a fairly regular basis, I'm sent information for events and produce a nice looking printed program in Word, though much of the same material also goes into slides in Keynote. (Keynote is used rather than PowerPoint so that Keynote Remote can be used.)
Anyway, there's a large volume of text I work with that I'm sent via email, and it has to go in both a Keynote presentation and a Word document, and requires all sorts of odd manual formatting to not break pages or slides at odd times, also requiring a good deal of manual restyling, since I'm not going to allow something I do to come out looking like something sloppy from the 1990s.
My hope is to write up a Ruby script that I can feed the source text to, and it'll go do all the processing for me, at least for Powerpoint or Keynote. I've normally had fantastic luck finding a gem for just about any format or service I've wanted to work with, but I haven't found anything that works with Powerpoint or Keynote.
My next thought was to have the Ruby code generate appropriate XML since both Office and I Work allegedly open the Office XML format, but I couldn't find any actual friendly documentation for human-writable XML code.
Is it wishful thinking to want to be able to do something like the following?
<SLIDE FORMAT="Title & Bullets">
<SLIDE_TITLE>
Lorem Ipsum
</SLIDE_TITLE>
<PARAGRAPH>
[etc.]
All I can find as far as converter scripts is all related to charts and tables and such which is of zero use here), usually revolves around opening or converting FROM Powerpoint or Keynote rather than creating, and furthermore generally seems to be for Windows using OLE or VBScript. This needs to run on the Macs they have there, so no Visual Studio stuff, Windows related scripting, etc will work. I don't HAVE to do it in Ruby, but that's what I'd be most comfortable with on the Mac end of things.
So is there documentation out there on a marginally friendly XML format for Powerpoint or Keynote, or even better, a Ruby gem for either?
If all you need to do is title + bullet point slides, you simply need to create an ascii text file. Each line of text will become the title of a new slide. But if the first character in a line of text is a tab, the line will become a first level bullet point on the same slide as the previous title. If two tabs, it indents the text to a second level bullet point and so on.
This becomes the title on slide one
This becomes the title on slide two
<tab>This is a bullet point, first level
<tab><tab>And this is a bullet point, second level
<tab>Back to first level bullet point
And another new slide
Once you have the text file, you can do File Open in PPT and force files of type to all files . and select your .TXT file. Or you can use Insert Slide From File to bring the .TXT file into an existing presentation.
There's a limit to the number of slides you can create at one go like this; 100 perhaps?
Note also that VBA disappeared in Mac Ofice 2008 but is back in Mac Office 2011, so if you can find examples of VB/VBA code that do what you want, you can use them on Mac, so long as it doesn't have to happen in Office 2008.

Using Mathematica to build presentations and documents

I use Mma mainly to solve relatively small problems.
I want to start using it also to prepare my presentations and documents, but I am having troubles to learn how to do it from the embedded help, and I guess some good resources may be available elsewhere.
Do you know any useful pointers (books, papers, videos ...)?
Do you have a "bag of tricks" to post here?
Edit
This question received two answers so far (#mzabsky's and Mr.Wizard's) and although both are useful, perhaps my concerns are much more basic. So I am posting an example of the kind of things I am unable to do (or understand how to discern how others did them).
I took the following example from The Mathematica Journal (the notebook at the left on the following image - click on the image to see full size):
So, some issues, just to get the idea of my troubles:
1) I copied the text to my .nb on the right, formatted it with the same style (text), but the appearance is different, so I guess the style definition is different. How can I copy the style definitions from one .nb to the other?
2) The table below the text block doesn't have an attached style. How was it formatted? Where is the background color defined?
I would like pointers to read (or videos to look, or whatever) about these issues. I don't want you to write down here a book on Mathematica formatting!

Create a Lecture Notebook
I use Mathematica to take lecture notes in real time without any major issues (while the proud TeX guys struggle hard to keep up :) ). I have also used it for most math-related homework/assignments I wrote during past two and half years on university.
Before you start, you may want to look at some of these video tutorials.
Also, a few recommendations from me:
Keyboard shortcuts are the key to type fast. Ctrl+9 for inline math cell, Ctrl+6 for superscript, etc.
Learn symbol identifiers for the "esc - symbol - esc" notation. "sum" for Sum, "es" for empty set...you can find list of these in the Mathematica documentation. I have encountered only very few symbols I wanted to type that don't have the esc notation name (for example, leftwards double arrow or double right tee).
Type all math-related stuff into inline math cells. The math cell will do some of the math related formatting for you - put spaces where they belong, render all variables and symbols in italics, etc.
Use the preformatted templates found in "New"->"Styled Notebook".
Do not use ENTER for breaklines, individual paragraph should go into separate text cells (Ctrl+Shift+D) so Mathematica can break the content into individual pages/slides correctly.
In-built Mathematica PDF export sucks big-time; I use CutePDF printer for this.
Also, save often and back up often (Dropbox/Syncplicity are the ideal solution), one misplaced keyboard shortcut can turn hundred hours of work worth document into a goulash (trust me, been there) :)
Example of lecture notes I took in real-time during lecture (it is in Czech, but that doesn't matter much).
I agree with all that mzabsky said in his answer.
Here's a few of extra things:
I find it useful to make statements using a Text or DisplayFormula cell then manually group a Mathematica check/proof to the statement which is then collapsed and can be displayed when you want.
The Writing Assistant Palette has quite a few useful constructions in it that you can learn from.
Finally, I found it really useful to make my own style sheet for a couple reasons:
1) the built-in ones are a bit ugly; 2) it really helps you to understand how the notebooks work.
To see examples of the stylesheet I made (which I don't claim to be perfect - I didn't bother making it work in all screen environments) look at some of the files in ftp://ftp.physics.uwa.edu.au/pub/MATH2200/2010/. I use a similar stylesheet in all of my notes - I have many research projects primarily contained in Mma notebooks, eg http://arxiv.org/abs/1102.3043.
Like Mr Wizard, I also recommend David Park's notes as a starting point. Also, you should study stylesheets that you like by going to the Format menu and clicking "Edit Stylesheet". Don't forget to follow the links through the cascade of stylesheets (version 6 onwards).
To answer the questions in your edit: Once you are viewing a notebook's stylesheet, you can save it, edit it, and use it in your own documents. Stylesheets in
$UserBaseDirectory/SystemFiles/FrontEnd/StyleSheets are automatically available in the menu. You can then use that stylesheet in any notebook by simply selecting it from the menu.
The formating in the screenshot that you posted is all contained in the stylesheet. This includes the grey background in the table.
Addendum:
When distributing notebooks to others, if the stylesheet is external from the notebook, then other people will not see it as you do. To include the stylesheet into the current notebook, you need code like
ss = StyleDefinitions /. Options[EvaluationNotebook[]]
fn = ToFileName[{$UserBaseDirectory, "SystemFiles", "FrontEnd", "StyleSheets"}, ss]
If[FileExistsQ[fn],
style=Get[fn];SetOptions[EvaluationNotebook[],StyleDefinitions->style];,
Print["Can not find file"]]
(Assuming the file is in stored in the conventional place)
Here's an EmbedStylesheet.m that is an improved version of the above.
A Mathgroup thread on embedded stylesheets, particularly here (John Browne) and here (David Park and Selwyn Hollis) might be of interest.
I find stylesheets problematical. In particular I don't like having to remember to embed a stylesheet before I give the notebook to someone else, or before I try to print from an unfamiliar computer. However, along with David Park's tutorial (referenced above by Mr Wizard), I find this advice from Bob Ueland very useful.
If you browse the back-issues of The Mathematica Journal you will see that articles are available in Notebook format. These may be a useful reference.
Edit
I cannot recall a good formatting tutorial at the moment. You can use Show Expression (Win: Shift+Ctrl+E) to view the code expression for a block, such as the table in your example. While one may not enter code by hand in the same form, it can give indications of the options or methods that are used. Code can also be procedurally produced as needed.
I will add links as I find or recall them.

What article discusses "Viewing code from 10000 feet"?

A few years ago I read an article about a neat way to analyze a large code-base.
The idea was to zoom out so far that patterns of indentation and block length are all that is really visible.
The author wrote about printing out code with very small fonts and looking at the results from 10 feet back. I believe the author also had some tools for reformatting code and producing images for this technique, in such a way that paper could be avoided.
I can't find the right search query to bring this up. Anyone have any ideas?
The text editor Sublime Text has a zoomed-out overview of your code on the left of the window, and can be used to scroll.
I've done this myself, that is print to paper with very small fonts and step back. If you want to avoid the paper route then perhaps you can print to PDF?
Or use and editor that can zoom in and out by changing font size. I use SciTE and Komodo Edit, both based on the Scintilla code editing engine and both allow me to hold down the ctrl key and use the mousewheel to change font size (just like web browsers).
With a bit of Google-fu I found references that this (ctrl+mousewheel) may also be implemented in Visual Studio and XCode. Can anyone confirm?
I think you are referring to Software Visualization? If you search for Code Visualizer, you maybe able to find a few products out there that does it but there are more focusing on aggregating the measurements information/metrics together for software comprehension and not necessary as a way to view or navigating to code only.
Some of the tools include Code city, code crawler or code visualizer. Michele Lanza and his team did some great work in this area in the recent years, however some only has support for certain language/platform so be mindful if they are going to be useful for you.
http://www.inf.usi.ch/faculty/lanza/
http://www.inf.usi.ch/phd/wettel/codecity.html
Could extract all the types, classes, etcetera, and put them into a tool such as graphviz and generate a graph.

Creating nice pdfs with ruby

I would like to create pdfs with ruby. One special need is embedding a picture into text (or a textblock), which means I need to be able to let the text flow around the image. E.g. the image should be in the rigth upper corner and the text should start left of the image and continue after the image by using the whole width of the page. How can I do this in ruby? Thank you for any suggestions!
In the past to get print quality PDFs in Ruby, I used rtex.
It's fast too, which is a real bonus.
Prawn to the rescue?
I like the html -> pdf approach. Although it is probably not the best option (prawn is) it makes it easy to design the pdf. See this website. You could also go for the approach documented at jimneath.org.
Good luck
iText is the heavyweight that will allow you to do anything you want with PDFs you can bridge to it with jRuby.
Another option I used was driving open office (it has a ui less option which you can automate from Ruby)
How about having Ruby generate some LaTeX code, then use pdflatex to produce the PDF?
Although I haven't done it myself I've seen people use a headless Open Office. You can control it from Ruby and use it to generate PDF files. You can even use an Open Office template and just fill in some elements into it.
