Is there a web service API that takes this type of a latex http-request:
http://some_web_service/texfile?texfile=
\new\documentclass[12pt]{article}
\begin{document}
bla
\end{document}
and returns:
bla.pdf
the Online LaTeX Equation Editor is perfect for this.
EG:
uses the following markup:
![equation using Online Equation Editor]
(https://latex.codecogs.com/gif.latex?x&space;=&space;\frac{4}{5}+\pi\Omega\int_{2\pi}^{\infty}{5\left\(\frac{\tau+3}{2}\right\)d\omega})
note that you will need to escape parentheses with a backslash, eg: \left\( stuff \right\)
If you look through the editor API documentation you might figure out that you can change the format from gif to png by changing the api url endpoint from /gif.latex to /png.latex.
There's also options to set a white background by using \bg_white:
![equation using Online Equation Editor]
(https://latex.codecogs.com/gif.latex?\bg_white&space;x&space;=&space;\frac{4}{5}+\pi\Omega\int_{2\pi}^{\infty}{5\left\(\frac{\tau+3}{2}\right\)d\omega})
See also this meta.stackexchange answer and this tex.stackexchange answer. I'm sure there are many more answers that point to this tool and implement it in different ways. IE: instead of using the url to generate a gif or png using markdown notation, or you could use html markup and bypass markdown or you could just drag the image over to your post.
I'm looking for the same thing and Latex Online seems to be the closest thing to what we need.
You just need to setup the server by yourself.
EDIT
I've written my own little Sinatra app for this: https://github.com/codegestalt/sinatratex
ScribTeX has a CLSI API, you can send CLSI requests from any platform to compile LaTeX.
I blogged some time ago about this along with a CLSI client written in F#.
The Common LaTeX Service Interface (CLSI) is a web service interface and implementation that exposes common LaTeX related capabilities (such as compiling LaTeX documents to different formats):
http://code.google.com/p/common-latex-service-interface/
(This interface is one of the ways that latexlab.org can compile latex)
Fundamentally, this shouldn't be any different than a build server like you see for lots of open source projects (along the lines of Koji for example). Ultimately, you would just hook into pdflatex instead of gcc.
Were you to be able to install software on your local server this wouldn't be too hard. Some combination of Perl / TT / latexmk along with a LaTeX system (e.g. TeXLive or MiKTeX).
I don't know about latexlab mentioned above. The closest thing I know of is http://www.tlhiv.org/ltxpreview/ , which perhaps you could wrap to do what you need (or even write a howto for your users).
Just for completeness:
GitHub or docker might do the trick.
It's basically a micro service implemented in java/spring boot, which is wrapping pdflatex. Urls are immutable and the pdfs are stored on disk/distributed storage. You'll have to host it on your own though. The code is pretty simple and you're able/allowed to customize it to your needs. See the "Scaling the service" section in readme for more details about setting up a production environment.

I am working remotely with some colleagues on a Rmarkdown document, and I would like to make a simple review of the file (especially the comment part and not the code), and then send it back to others with my reviews embeded in the document, like a word document review or a kind of Overleaf review. I have made some research on the topic, but I didn't find something that feet my needs as explained. Please, Is there a way to add some review in a Rmakdown document and sent it back (either online or not)?
Take a look at Etherpad
Etherpad is a highly customizable Open Source online editor providing collaborative editing in really real-time.
Or, better: StackEdit
With StackEdit, you can share collaborative workspaces, thanks to the Google Drive synchronization mechanism. If two collaborators are working on the same file at the same time, StackEdit takes care of merging the changes.
Or, even better: HackMD
HackMD is a realtime, multiplatform collaborative markdown note editor.
This means that you can write notes with other people on your desktop, tablet or even on the phone.
I suggest you considering trackdown https://claudiozandonella.github.io/trackdown/
trackdown is an R package that offers a simple answer to collaborative writing and editing of R Markdown (or Sweave) documents. With trackdown, the local .Rmd (or .Rnw) file is uploaded as plain-text in Google Drive where, thanks to the easily readable Markdown (or LaTeX) syntax and the well-known online interface offered by Google Docs, collaborators can easily contribute to the writing and editing of the narrative part of the document. After integrating all authors’ contributions, the final document can be downloaded and rendered locally.
You can find more details at this answer https://stackoverflow.com/a/68014082/12481476 or in the package documentation https://claudiozandonella.github.io/trackdown/

OData is used by Netflix and in many of Microsoft's products (servers: CRM, Sharepoint, SQL Server; clients: Excel).
While OData is interesting, it has it's own set of benefits and trade-offs.
I've designed and build a custom search engine for internal use. Many developers are using the search engine for reporting and lists, replacing the reports and custom search/filter functionality in each line of business app with this search engine.
I have a decent system to allow querying/filtering in my search engine. It's all url driven so it's easy to use.
At this point, I want to add a little bit more functionality to the URL "command line". OData is a tempting choice because we use a lot of Microsoft tech already. It also has standard language for filters with Boolean logic, etc.
Are there any other legitimate standards based REST frameworks like OData that I should look at?
I'm not sure I need the full OData stack for what I'm doing. My simple query string based filtering is working very well at this point. Just want to conduct some due diligence so I can make an informed decision.
Thanks.
Edit
What I'm looking for is more of a framework for creating my search API. Lucene/Solr use a url syntax http://lucene.apache.org/solr/tutorial.html as does OData. Lucene/Solr aren't exactly what I'm looking for and are too complex for my scenario. However, they have a well defined url api.
I'm looking for any other well define url-based api examples. I want to see the "prior art" for defining a query/search syntax based on a url and query string parameters.
While some will certainly argue, rolling your own is certainly an option; provided you can release a consumable schema and syntax or API library. Given that you carefully research the current standards landscape and borrow from established (albeit unfitting) implementations, you (and supporters) could be inclined to produce a new or extended standard; perhaps one that solves an unsolved problem.
However, obligatory:
After some research it appears that no, there is not really a good alternative to OData at this point.
I'm saying this based on the features of Odata. Hopefully we'll see an alternative at some point.
Facebook is developing GraphQL. Data can be queried using JSON queries:
{
user(id: 3500401) {
id,
name,
isViewerFriend,
profilePicture(size: 50) {
uri,
width,
height
}
}
}
At the moment it is not usable. According to the Changelog they plan to release it as a kind of specification.
Here is another whitepaper
Google is pushing for GData, which seems feature crippled.
If you are looking for a web compliant search mechanism, I suggest looking at Open Search

I would like to generate documentation for a RESTful web service API that is written in Python. Ideally it would look like Yahoo's RESTful web service docs. Does anyone have any ideas or references?
The Sphinx project (www.sphinx-doc.org) is the current state-of-the-art in Python documentation. It's really powerful and flexible... so also somewhat confusing. Still, I think it is your best bet.
There is excellent documentation on their site on how to set up the document source files and the process of building them in to finished documentation such as HTML. The part that should interest you is its system of incorporating docstrings from Python source, which I'm assuming you've been doing for the methods that serve your REST requests. Note that this will NOT magically interpret what is going on, but will bring all the named elements and their arguments (if appropriate) and provide a good framework for you to put in the appropriate documentation.
Assuming you have all of your REST functionality in a module named restapi.py and it is simply in your src directory of your project, you need to do two things to get Sphinx to automatically generate the documentation:
First, include the autodoc extension and add the src directory to Sphinx's path in conf.py:
import sys, os
sys.path.append(os.path.abspath('sphinxext'))
extensions = ['sphinx.ext.autodoc']
sys.path.append(os.path.abspath('src'))
Then in the Sphinx
.. automodule:: restapi
:members:
Note: this information was taken straight from the Sphinx "First Steps" document with minimal reordering. Do have a look at that document and the rest of the site if this seems like it would serve your needs.
Unfortunately I don't know anything specific that will help you in Python specifically -- However just as points of reference, you might take a peak at the WADL specification that the JAX-RS java spec is using -- https://wadl.dev.java.net/ -- Additionally, there is a xslt that will transform the wadl into html -- http://www.mnot.net/webdesc/
They use the yahoo REST API's as examples.
It sounds like you're not making a REST API, but simply an RPC. There's generally no easy, automated way to assemble a REST API, which should primarily be a description of your media types.
If what you mean is that you want something to pull together all the URIs in your service and put them into an API document, that's not REST at all, due to all the coupling from URI to resources.

I am looking for a redistributable component to convert HTML to PDF.
I would - at the moment - like to avoid using a "PDF printer", as this requires a printer installation and some user "playing around" in the printers panel might break that feature.
The HTML is available in a Browser control or as external file. The HTML is normally fairly simple, but customers can create their own templates, so a "good range" of HTML should be supported.
Should be accessible for an automated process from C++ - DLL / COM / external executable with command line support are all fine.
Commercial is fine, but in the thousands is not an option right now.
So, which components do you know or can you recommend?
PDFCreator can function as a virtual printer but it's also usable via COM. The default setup even includes COM examples.
You can check the COM samples in the SourceForge SVN repository right here: http://pdfcreator.svn.sourceforge.net/viewvc/pdfcreator/trunk/COM/
If you have Microsoft Word installed, I guess you could automate the whole process using the "save as pdf" plugin that can be downloaded from the Microsoft Office Site.
You would automate word then open the HTML document inside word, then output as PDF. Might be worth a shot, if you're developing in a Microsoft Environment.
You might want to have a look at PDFReactor

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:
