* Introduction
** Purpose
To evaluate many features of orgmode, such as
- drawing with code
- evaluating results of code snippets
- exporting orgmode file to pdf slides
#+begin_quote
All the orgmode "source text" is hosted in github: https://github.com/kimim/orgmode-examples
#+end_quote
** How
Following tools are used in this file:
- [[https://www.msys2.org/][MSYS2]] provides many tools and libraries
- [[https://www.graalvm.org/][GraalVM]] JDK supports Java, JS, R and more
- [[https://www.gnu.org/software/emacs/][GNU Emacs]] with [[https://github.com/kimim/kimim-emacs][kimim-emacs]] configuration
- [[https://orgmode.org/][Org Mode]], including org-babel, org-export
- [[http://tug.org/texlive/][TexLive]] with [[https://github.com/kimim/beamertheme-hippo][beamertheme-hippo]] style
- [[https://plantuml.com/][PlantUML]], [[https://graphviz.org][Graphviz]], [[https://mermaid-js.github.io/mermaid/][Mermaid]], [[http://ditaa.sourceforge.net/][ditaa]], \LaTeX{} [[https://www.ctan.org/pkg/pgf][tikz]] package
- [[http://lilypond.org][LilyPond]] for music notation
- [[https://inkscape.org/][Inkscape]] to convert svg to pdf, during orgmode-pdf exporting
* Preparation
** Emacs settings
You may need to use kimim-emacs configuration:
#+begin_src shell :exports code :eval no
# backup existing emacs config
cd ~ && mv .emacs .emacs-backup && mv .emacs.d .emacs.d-backup
# clone this config
git clone https://github.com/kimim/kimim-emacs
# copy default .emacs to ~
cp kimim-emacs/.emacs ~
#+end_src
** Emacs and Orgmode version
Firstly, let's check GNU Emacs[fn:1] and Orgmode[fn:2] version:
#+begin_src emacs-lisp :exports both :eval no-export
(concat (emacs-version)
"\nOrgmode " (org-version))
#+end_src
#+RESULTS:
: GNU Emacs 29.1 (build 2, x86_64-w64-mingw32)
: of 2023-08-03
: Orgmode 9.6.6
** TexLive and Beamer Theme
Install TexLive[fn:3] to ~~ and clone beamertheme-hippo[fn:4], and
update \TeX{} cache:
#+begin_src shell :exports code :eval no
git clone https://github.com/kimim/beamertheme-hippo \
/texmf-local/tex/latex/beamertheme-hippo
mktexlsr
#+end_src
** Inkscape version
Install Inkscape[fn:5] to convert SVG image to PDF.
This is inkscape version on my Windows 10:
#+begin_src shell :exports both :results pp :eval no-export
inkscape --version
#+end_src
#+RESULTS:
: Inkscape 1.3 (0e150ed6c4, 2023-07-21)
* Drawing in code
** PlantUML settings in Emacs
Download plantuml.jar[fn:6], and set jar-path
#+begin_src emacs-lisp :exports code :eval no
(require 'url-handlers)
(url-copy-file "https://nchc.dl.sourceforge.net/project/plantuml/plantuml.jar"

(add-to-list 'org-src-lang-modes '("plantuml" . plantuml))
(add-to-list 'org-babel-load-languages '(plantuml . t)))
#+end_src
** PlantUML version
Here is the version info on my machine, including JVM, dot and graphviz:
#+begin_src emacs-lisp :exports outputs :eval no-export
(shell-command-to-string
(concat
"java -jar " org-plantuml-jar-path " -version"))
#+end_src
#+RESULTS:
#+begin_example

Phoenix! Phoenix! How virtue has declined.
It can't wait for the future or catch up with what's behind.
When the Dao works in the world, the sage man works his ways,
When the Dao has disappeared the Sage lives out his days.

In times like these just keep far from the shackles and the blade.
Good fortune's lighter than a feather, but none knows how to bear it,
Disaster's heavier than the earth, but none knows how to dodge it.
*** col3 :BMCOL:
:PROPERTIES:
:BEAMER_col: 0.33
:END:
Enough! Enough! These toils of virtue serving man,
Danger! Danger! Escape! – draw the line in the sand.
Brambles, brambles, don't cut me as I go,
Twisting, twisting, my feet stay free of woe.
