forward and inverse search for Rmarkdown (request) - r-markdown

I used Latex for many years and recently decided to switch to Rmarkdown, especially after the development of notebooks, bookdown, etc.
However, I'm frustrated by the fact that I cannot use forward and inverse search when using Rmarkdown files. First, I thought this was an issue with my system configuration and Rstudio. However, I was informed in another forum that forward and inverse search do not work with Rmarkdown files, but only with Rnw files.
I would like to suggest the implementation of forward-inverse search when using Rmarkdown, bookdown, etc. It would make revising our documents, books, websites, a lot easier.

How can I programmatically generate documents using TeX?

This applies to popular languages used for web development e.g. Python, Java, Rails etc.
I want to be able to programatically generate TeX documents. For example a user submits a form and a field contains the LaTeX code to be typeset and the web service returns the typeset PDF.
Are there libraries available for such a task? I can't find any.
The only other solution I can think of is to use external shell command functionality that's usually available. But this is a bit messy.
Some time ago I created an Etherpad lite plugin that allows you to compile the LaTeX serverside. FlyLaTeX does it similarly, but didn't really work for me and the code looked pretty messy and almost impossible to fix and debug when I was having a look at it about 4 months ago.
Basically you need to generate a temporary file that you can then compile with LaTeX.
I don't know of any generation libraries, but LaTeX is quite easy to generate. However, pandoc can convert different formats into LaTeX.
There is also https://github.com/manuels/texlive.js/ which is an emscripten-based clientside port of LaTeX (that unfortunately has very limited capabilities and is quite large).

Web Design - Templates vs Include

I am currently developing a website. I would like to separate content and presentation. I am currently using a Dreamweaver Template to achieve this. However, I find that Dreamweaver's edit regions are very limiting in the design view. I have found that the same goal can be achieved by including the header and footer of my website.
What are the pros and cons of using includes rather than using templates?
First, if I were to rephrase your question, it's more like asking "Should I by a wire frame of a kite or by the glue to stick together what I'm making?" And then, you ask about the pros and cons of buying the wireframe against buying the glue. There are far too many variables as you can see...
And back on your your question... At some point your template will use include files. And for a start, it's worth knowing what you're thinking... Let's look at some basics.
Web design - usually refers to making websites that aren't really interactive. They don't have server-side elements. So most of the site has 'static' contents. If this were the case, you're better off with DreamWeaver, particularly if you're not into html/css editing.
Web development/programming - starts off with something as elementary as mailing a form, to highly interactive sites like FaceBook. Here you'll need to use some server-side language, usually like PHP, ASP or JSP. The choices are many but you've got to choose your own platform or combination of them.
Now to the second option (above). If for example, you were building a site using PHP, one of the nice things you'll do is to include your header, footer and side panels that need to be repeated across all pages. This way, you'll eliminate the need to re-write those sections. But if you were using a program like DreamWeaver, it does this duplication for you. Yes, it physically copy-pastes those sections into every file that needs it. Of course the end result may not be any different. But as a developer, you will be tied down to the DreamWeaver platform or for that matter, any other specific platform.
On the other hand, if you get used to working with an editor like NotePad++ or GEdit, you may switch between editors at any time. But you have the task of hand-coding everything from scratch. But then again, since you would use include files to bring in your headers and stuff, you save development time as well.
I don't know how much of html/css or php you know, but here's one of my demos to show you how to hand-code a site. This ain't complete but you should get an idea.

Creating a PDF reader in C++

So I wanna make a PDF reader using C++ as a hobby project. The problem is I am not finding much of head start so if anyone has worked on similar project please guide me, a few web links would be great! I will be using windows environment and Visual studio.
If you want to simply "host" an existing PDF reader (such as Acrobat or Foxit) in your own window, then you'll want to look in to ActiveX.
Alternately, if you want to do your own PDF decoding, then the best place to start would be find a soft couch and cozy up with the PDF format specification, and in particular, ISO 32000-1. It's a real page-turner.
http://www.adobe.com/devnet/pdf/pdf_reference.html
Adobe's publication about the details of the PDF file format.
There are PDF components as well, if you want to go that route, but the majority of them are either not free, or already have a UI of their own. Just tossing a PDF component into a form doesn't strike me as much of a hobby project. :)
You might find this article on parsing Reg files using Boost Spirit a useful starter. I've used Spirit before for parsing complex data but I think you're biting off a mighty big challenge!
If you want to look at existing parsers, try PoDoFo in C++ or the lexing side of Panda, in C.

Workflow to Turn Wiki content into a system manual

We're in the middle of deploying a new software system to lot's of users in lot's of places (200+ users over 8 countries). In the past we've written a manual for the users, then update it every so often. This works ok, in that all the users ahve the same manual and it covers the main things but it has it's problems, like it doesn't get updated that often, we sometimes miss updates, and some users will have old copies.
We've been talking about using a wiki during the testing and deployment phases to build a knowledge base about the system. Ideally we'd then like some way to convert that into some form fo electronic document that we can then 'pretty-fie' and send out as the official manual, as well as letting users use and update the wiki.
Has anyone else done anything similar ? Any suggestions for wiki systems, workflows, document formats etc?
Most wikis support export via PDF e.g.:
MediaWiki PDF Export
DokuWiki PDF Export
TWiki PDF Export
You can write something that generates LaTeX from the wiki and renders a manual to PDF. With packages like hyperref you can retain cross-references as hyperlinks.
Additionally, you can integrate content from multiple sources such as a data dictionary into the LaTeX document, which can be mixed and matched with the wiki content. You could also set the architecture up so it can support cross-referencing that goes either way.
Framemaker could also support this using generated MIF files, and you could also use Lout in a similar way or convert your wiki content to docbook, which would allow you to use any of the many rendering options available to that format.
As an aside, the following Stackoverflow postings discuss various systems for maintaining documentation.
Application (Not a Markup Language) for Producing a User Manual
Can LaTeX be used for producing any documentation that accompanies software?
What tools are used to write documentation?
What tools does your team use for writing user manuals?
How best to write documentation (ideally in latex) targeting both the web (html) and paper (pdf)?
Best tool(s) for working with DocBook XML documents?
What is the recommended toolchain for formatting XML DocBook?
Is a successor for TeX/LaTeX in sight?
Madcap Flare is a help-and-manual authoring tool that uses HTML for the source of each topic. You could pretty easily do a mass import of the Wiki pages. Would then require some cleaning but after that you have a nice single-source system that can output CHM, web-browsable help, PDF, DOC/DOCX, etc.
How are you storing the help source at the moment? Is it MS Word files, MS help, LaTeX?
If you put your help source files under version control then you will get all the benefits of a wiki without having to migrate to a new system - people can make edits to the help files easily - those changes can be tracked, reverted etc. and you get the prettified manuals as before.
I followed Node's links and came across some mediawiki pages that I thought were noteworthy.

I gave a previous answer which may be useful for the "wiki to PDF" part -- look at using the open source PediaPress code or functionality. You can get ODFs from it too, although their PDFs are already quite pretty (but you might want to rebrand it and restyle it for your company I suppose).

C/C++ source code visualization? [closed]

Basically I want tools which generate source code visualization like:
function call graph
dependency graph
...
Doxygen is really excellent for this, although you will need to install GraphViz to get the the graphs to draw.
Once you've got everything installed, it's really rather simple to draw the graphs. Make sure you set EXTRACT_ALL and CALL_GRAPH to true and you should be good to go.
The full documentation on this function for doxygen is here.
I strongly recommend BOUML. It's a free UML modelling application, which:
is extremely fast (fastest UML tool ever created, check out benchmarks),
has rock solid C++ import support,
has great SVG export support, which is important, because viewing large graphs in vector format, which scales fast in e.g. Firefox, is very convenient (you can quickly switch between "birds eye" view and class detail view),
is full featured, impressively intensively developed (look at development history, it's hard to believe that so fast progress is possible).
So: import your code into BOUML and view it there, or export to SVG and view it in Firefox.
For the free version:
source is on Github as DoUML
Installers can be downloaded from http://www.bouml.fr/download.html
You can look at different tools for software design and modelling (Rational Rose, Sparx Enterprise Architect, Umbrello, etc). Majority of them have some functionality to reverse modeling by source code, and getting UML class diagrams, and sometimes even sequence diagrams (and this is very close to functions call graph).
But after you get some pictures on really big project code base you could realise that such graphs are rather hard to read and understand. Unfortunally visualization capabilities of complexity are very limited.
As for me, using a "divide and rule" idiom is more convinient approach. You can extract different functionality blocks or layers from your some code base (just sorting cpp-files by different folders sometimes enough). Another way is to use some scripts (bash, python) to create simple csv tables with interested parameters of files, classes or functions like "number of dependencies" etc).
If you use Visual Studio, the 2010 Ultimate release lets you generate sequence diagrams and dependency graphs. However, the release currently supports only .NET application projects.
The team has gotten lots of interest in supporting C++ in a future release, so you might want stay tuned. In the meantime, you can post in the VS 2010 Architectural Discovery & Modeling Tools forum at http://social.msdn.microsoft.com/Forums/en-US/vsarch/threads to request an update. I know the product team loves hearing customer feedback about the tools.
In the meantime, you can learn more about creating sequence diagrams and dependency diagrams from .NET code in the following topics:
