Codename: scaltex-2

Install bower for javascript dependency management. Fetch the js dependencies with:

cd public
bower install

Note: public/lib is managed by bower. Note: If you fetch the dependencies "freshly", you should apply the At.js patch! See section Patching At.js. Note: The bower dependencies are commited to git, to preserve the entire code. If you are using the already commited client side javascript dependencies, you don't have to apply the At.js patch.

Install CouchDB, which should (for example) listen to http://127.0.0.1:5964/.

Install sbt to start the server, then simply run:

cd scaltex-2
sbt "run --init --home http://127.0.0.1:5964/mydocument"

View the Main Document, Meta Document or the LaTeX Code. The init flag pushes a simple test document to mydocument on the database, don't set init to load an already existing document. With the home flag you can specify, where your document resides.

Changelog

• v0.6.1: 2014-08-22

  • Litte fixes in code, added some example figures (for thesis)

• v0.6.0: 2014-07-28

  • This version gets a DOI (digital object identifier), therefore added bower dependencies for preservation purposes.

  • Added new documentelements: Code, Math, Quotation, Reference, Footnote, ArabicList, RomanList, List and Spray

  • Added LaTeX-Code projection under http://localhost:8000/latex

  • Various Bugfixes

  • Switch between 'send actor state updates every time' and 'send updates only on state change'. Do a HTTP GET on http://localhost:8000/switch. Attention: 'on change only' doesn't doen't reload the entire document, but it is faster because the browser isn't flooded by updates.

• v0.5.0: 2014-06-17

  • Introducing meta document at location http://localhost:8000/meta You can use it for hidden elements, which are only interesting as reference within the actual document.

  • Remove elements within the hierarchy.

  • New document elements: Figure, Python Code, Table of Contents, Chemistry (Ketcher).

  • Added a Command Line Interface. init creates a new little example document, home specifies where the document is stored. sbt "run --init --home http://127.0.0.1:5984/mydocument"

• v0.4.0: 2014-06-05

  • Introducing a more flexible and "generation friendly" architecture. Complete refactoring.

Contributions and Patches

My contributes to other open source projects used with scaltex:

• dijon - Dynamic Json in Scala
  • Commited Bugfixes
  • Issue reporting
• Xitrum
  • Commited to documentation
  • Issue reporting
• Ketcher
  • Branching and made available to bower dependency management

Patching At.js

Via default At.js adds after a autocompleted term an space character ( ). To avoid this in v0.4.10 you must alter line 340 in "jquery.atwho.js" to:

content_node = "" + content;

The orginal line was:

content_node = "" + content + "<span contenteditable='false'>&nbsp;<span>";

Note: This should be contributed to future versions of At.js. This patch maybe should introduced as new settings flag, to be enable or disable spaces after autocompleted terms. Here's the discussion on github.

Appendix

Emphasized technologies, hints or other useful stuff which made implementation easier. And the documentation about found sources of technologies, which put out to be unsuitable or may useful (promising) for future work.

Used

Bibtex

The References documentelement uses the scala bibtex parser from bibimbap.io. I've resected it, so that only the bibtex parser is left. This bibtex parser is in src-bibtex and is compiled together with scaltex. Note: It needs as dependency Apache commons-lang3.

Scaling: clustering and modularization

How could scaltex be modularized? Wrap every (bigger) document element in an Docker instance, to automatically compile, deploy document elements on meta model changes?

Hold the meta model in the database? Generate code of the actor system on meta model basis and deploy it (with docker)? The so started actor system could expose Akka's communication protocols, for distributed documents.

• https://www.docker.com
• https://coreos.com
• http://osv.io

Or use a plugin architecture like OSGi to inject other meta models:

• http://felix.apache.org/
• iPOJO
