WikiViz je automaticky generator brmlabich vizitek z projektu ktere jsou popsane tady na wiki. Napriklad [[project:brmhistology:start]] a [[project:bioosm:start]] uz koluji...

==== How it works ====

WikiViz.sh je bashovy script, ktery stahne prehled projektu z wiki, vyparsuje URL nahledoveho obrazku a z URL projektu vygeneruje jeho QR kod.

Oba obrazky vlozi do templatu wikiviz_sample.tex a zkompiluje ho pomoci pdflatex do PDF (dvojity pruchod kvuli dynamickemu prepocitani velikosti nekterych elementu).

Predni strana je [[https://brmlab.cz/_media/brmlab-business-cards.pdf|logo brmlabu s kontaktnimi informacemi]].

==== Bash script ====
<code bash wikiviz.sh>
#!/bin/bash
#
# Generator vizitek z brmlabi wiki
#   $1 = nazev projektu pro ktery se ma vizitka vygenerovat, pokud neni zadano, vygeneruji se vsechny
# Zavislosti: pdflatex (+ amssymb, tikz, multicol, xcolor, calc, graphicx), wget
#
