I'm currently using Inkscape but the so-called command-line mode is really slow as they require –most of the time– the GUI.
Current Code
inkscape -f input.svg --select=hanzi --select=pinyin --verb=SelectionUnion
Creating a single union and save the file this way took ~2s (after reducing fonts list). I need to repeat this operation 20k times and it took me ~12h to accomplish.
So I'm looking for an alternative solution to create this union.

I created a gist to show input/ouput file: Hanzi Pinyin Font from multiple elements to a single (Union path operations)
Question
How do you recommend doing this either using a CLI tools or writing an XSLT sheet? Is it even doable with XSLT?
This is not an XML transform you're doing, what you're actually doing is taking some text e.g. ABC and converting that to a path which draws out the letters A, B and C as lines and arcs.
You'd need to use something which can understand the fonts you're using and how they are rendered in order to do that and as fonts aren't in XML format, you can't use XSLT to do it.

Our application can generate some fairly long report files interactively. We use C++ to generate all the output, but redirected through a TCL console and TCL channel so we can take advantage of output logging etc.
Is there any common way to support paging of output in C++. I've casted around but can't find anything.

OK, so the situation is that you're writing to a Tcl_Channel that a Tcl interpreter is also writing to. That should work. The simplest way to put paging on top of that is to make that channel be one of the standard channels (I'd pick stdout) and feed the whole lot through a pager program like more or less. That'll only take you a few seconds to get working.
Otherwise, it's possible to write a channel in Tcl 8.5 using just Tcl code; that's what a reflected channel is (that's the Tcl 8.6 documentation, but it works the same way in 8.5). However, using that to do a pager is going to be quite a lot of work; channels work with bytes not characters. It's probably also possible to do it using a stacked channel transformation (8.6 only).
However, if sending the output to a Tk text widget is acceptable (I know it isn't precisely what you asked for…) there's already a package in Tcllib for it.
package require Tk
package require tcl::chan::textwindow
pack [text .t]
set channel [tcl::chan::textwindow .t]
puts $channel "This is a simple test."
That (write-only) channel will work fine if you pass it to your C++ code to use. (You can inspect the source to see how it is done if you wish; the code is pretty short.)
I am looking for a good java library to manipulate box, arrows and labels in order to dynamically create and fill diagrams like the following and render them to a png :
Another example
I can create a static template to be filled later, but I will need to dynamically create labels for every box and edges in the diagrams.
For now I have tried using batik to manipulate an svg template but creating multiline labels for the edges is proving quite complicated. The SVG way with batik seems to force me to create 1 text object for each label line with absolute positioning for each which is a real pain.
I would like to be able to define the label specifying only the text and the link they relate to, eventually some hints as to how it should be placed and let the library place them.
Any suggestions ?
If this is in a commercial scenario, the Java graph drawing library yFiles can be a good match for your requirements:
You can use a convenient API to create and style your diagram and automatically layout the diagram with lots and lots options to constrain the resulting layout to suit your needs.
Multi-line and (simple) HTML labels are supported out-of-the-box.
Also you can export to PNG (as well as other pixel based image formats) and vector graphics formats like SVG, PDF, EPS.
This can be done both in a regular Java (Swing) application as well as in a headless environment (e.g. to create images on a server and to send them to a web-based thin client dynamically).
To get a feel what can be done using that library, I suggest you take a look at the freely available graph editor application "yEd" that is based on yFiles and lets you try out the above steps in an interactive manner.
(Disclosure: I work for yWorks, but on Stackoverflow I do not represent my employer.)
OK, so here's the background:
We have a third-party piece of software that does a lot of complicated stuff to generate an XML file from a lot of tables based on a wide array of business rules. The software allows you to apply an XSL transformation by supplying an XSLT file as part of its workflow, before continuing on in the process, which is usually an upload to one or more servers, based on more business rules.
Here's the problem:
One of the elements (with more on the way) this application is processing contains RTF text, and needs to be converted into formatted HTML before being uploaded. There are no means of transforming the XML inside the application other than through an XSLT file, and once we output the file, we cannot resume the workflow. My original thought was, "Easy! someone must have written a few XSL transforms for converting RTF to formatted HTML!" Hours of searching later, I must conclude I either suck at searching or it's awfully obscure.
Disclaimers:
I know the software is pretty darned limited; I'm stuck with it.
I know there are a lot of third-party tools to do this; they are not available to me because I would need to run them externally.
I know that this is not a pretty or efficient thing to do with XSLT. Changing that is not an option for me at this point.
If I cannot find a means to do this through pure XSL transforms, I will need to output the files locally, run the extra process, and take the destination routing on through a custom process. I really don't want to do that.
Does anyone have access to an XSL transformation function/ scheme that will allow me to do this natively in the application? Perhaps a series of regular expressions I could use or something?
So it turns out that external scripts can be invoked from the XSLT. It seems I will be using another scripting language to get this to work. I'm a little bummed there was no other answer available.
all I want is to create circles (from data) on a grid for specific sets of data with different colours. These might be objects I have created to be placed on grid or from the program itself. I was using POVRAY but it is massively complicated and I don't have the time. Unless anyone has a tutorial on how to read data from files and extract all the numbers and used successfully in .pov files.
There are several programs/environments (not C++) that can do this directly. One is gnuplot; another, more robust tool is R. Although with R there is a bit more of a learning curve to really get moving.
Have you considered GNUplot?
It has a simple syntax, so you can just convert your data file into an input file for gnuplot.
What is the best tool to make complex (multi-line) regular expression file contents searches with good reporting capabilities?
I need to make a report over large Java/JSP code base and I have to make some charts afterward.
Eclipse is rather good at searches, but it does not provide good report of what is found. It just shows the tree of files, but I would like to see a table with columns corresponding to full match, each group, file name, file path, file date, may some version control information etc. Then I can transfer this table to Excel and make some graphs that I want.
Is there some generic file system search tool that has such capabilities? Or maybe there is some Eclispe plugin that can give better reports (note that I'm stuck on eclipse 3.1.2)?
Agent Ransack, TextPad, and UltraEdit allow you to perform regular expression searches against the file system. My favorite is Agent Ransack as you can specify regular expressions for the file names and for the content.
PowerGREP (on Windows) can be used to do (most of) that. You can define the format of your search results quite freely. I haven't tried yet to also add file meta information to the search results, but that should work. Not sure if you can add version control information (where would that come from?) - perhaps if you could be a bit more specific, I could check.
Other than that, why not write a small Python/Ruby/Perl script like JasonTrue suggested?
For searches over code bases with queries that understand the language structure, look at SD Search Engine. This tool indexes larges source base to provide very fast query response.
Queries are stated in terms of langauge elements (identifiers, operators, strings, ...) with constraints over the language elements (including wildcards and regexps on identifiers, strings and comments, as well as range constraints on numbers). Language whitespace and linebreaks (and comments unless you insist) are ignored.
If you want to do a plain regexp search on file character content, you can do that too but you don't get the speed advantage of the index, runs more like regular grep.
The interactive query result is shown in a hit window with other hits; by clicking, you can go to window containg the full source code of a hit.
In logging mode, all hits found are written to a log file with N lines of context, where you configure N. That's probably the report you want.
um... grep -r ?
Or ruby/perl/python, if you want to have more control over the final output; it sounds like what you're after would only be a few lines.
