Re: [O] org-mode, tikz and beamer
Hello Cédric, First, apologies for the delay. I am swamped with a lot of things for a while now, makes my responses rather irregular.

I can prepare a short example which generates the tex and pdf files if needed. The script probably gives for now a good idea. You can also look at the enclosed generated tex file to see how the tikz language. I think you forgot the Makefile. Aside from that, I looked at the script, and the Org file, albeit not very thoroughly. My impression is, it is a really nice effort but I think it's unsustainable. You have to duplicate a lot of work, and since you do it in a shell script, you are limited. Here are a few particular points: - You reimplement the Org parser. This of course means you do not support a large part of the standard syntax[1]. It's not future proof either. For the same reasons, it is very brittle. Org-element does a great job of parsing, you should use it. - You seem to rely on specific cookies, like `%%%' (and maybe abusing tags like noexport?). This is introducing _new_ syntax. Again, since this is outside of org-element, there is no way to ensure robustness and reproducibility. Basically, the shell script looks recursively into the org file and creates nodes for the tikz headline mindmaps. Thus, there are parent nodes and children nodes. During that excursion, two kinds of files are created: the tree files and the contents files. The first ones are tex files with tikz mindmaps that must be inserted at specific locations at the final latex compilation step. One tree file contains the parent node with all the children files. This part sounds good. The contents files are org files and are converted into tex files via the org-mode export command in a batch way. In the shell script, hyperlinks are added to these newly converted tex files. This, I'm not completely certain. If I got this right, you export one file per beamer frame? Is that right? I also see you do a bit of editing with sed. Again, I think this makes it too brittle, too many assumptions about what is present and what is not. At the end, the assembly of all these files is done before compiling. Numbering of sections through the recursive call is important so that links work properly as you notice. Links allow one to go back and forth the document. To go back, the idea is to click on the headline. If a node exists without content, the links sends you the beginning of the file or something like that. This part I'm not sure I quite understand. Shouldn't normal LaTeX referencing mechanisms (à la \label and \ref) be able to handle this? Anyway, after looking at the script I'm convinced this endeavour is better pursued in lisp. I think it would help if you draft a document outlining the Org elements you want to map to which specific tikz features/commands. You will then have a list of leftover info that tikz still needs to achieve the end goal. At this point others can suggest how you could communicate these missing info to tikz. E.g. you already have one suggestion from Bernhard, but I think it is probably too generic. If you manage to pursue this, I think the outcome will be a new Org backend, possibly derived from ox-latex or ox-beamer. Please don't be afraid to learn lisp, although it is hard to master, it's easy to pick up. I think the list will be more than willing to help you with that. Also, I think this is not a easy project. It will take some iterations to get to a version that can be test widely (by say putting in an experimental branch or something). While proof reading my email, I just realised ox-koma-letter might be a really nice place for you to get familiar with how to repurpose Org syntax to translate info to the backend in different ways. Have a look. Hope this helps, Footnotes: [1] Do not underestimate this aspect, Org users have a way to come up with interesting ways to use features that were not envisioned during development! -- Suvayu Open source is the future.

Re: [O] org-mode, tikz and beamer
Hi Cédric, If I understand it correctly, you want to include a graphical representation of you headlines into you beamer file, created via tikz/pgf. That sounds quite similar to what I'm doing at the moment, only I create gantt charts instead of mind maps. As far as I can tell, the best possibility to do that inside of emacs, is to use custom dynamic blocks. http://orgmode.org/manual/Dynamic-blocks.html Simply create your own org-dblock-write:... function that parses the file and creates the tikz output you want. You can have a look at org-dblock-write:clocktable and org-dblock-write:columnview for inspiration. I think using org-element-parse-buffer and org-element-map should get you what you need. You can also have a look at my gantt chart creation here: https://github.com/HeyFlash/emacs-stuff/tree/master/experiments (One el file and one org file for testing) You can probably ignore most of the file, as you don't need the complex time calculations I do. Keep in mind that this is wip and I'm not an experienced elisp / org person, so if anyone has better suggestions, listen to them. I will be without internet from later today until the middle of next week, so if you have any questions I will not be responding until then.

Mai 2015 16:41 An: emacs-orgmode@gnu.org Betreff: [O] org-mode, tikz and beamer Dear org-mode users, I have used org-mode for some months now. I find it very useful. I have recently used it to prepare mathematic teaching lessons using the beamer exporter. I wanted to combine org-mode and tikz latex's package from latex In order to insert some kind of mind-mapping from the headlines between the main parts of the lesson. I enclose an example so that you can see what I am talking about. Note that you can move forth and back through the presentation with hyperlinks. Note also only the chapter Droites dans le plan is filled so most of links fail. I have done that from a single org-mode file using shell scripting calling org-mode and emacs in a batch mode way. Before improving my shell script, I would like to know if there is a proper way to handle that within org-mode in lisp language. I have no idea about how to do that but someone may know if it is possible or not, and may give me hints to follow so that I could have a try. Thanks, Cédric Ody
