MathJax Support

Inisialisasi 

<script type="text/x-mathjax-config">
  MathJax.Hub.Config({
    showProcessingMessages: false,
    tex2jax: { inlineMath: [['[latex]','[/latex]']] }
  });
</script>
<script>
window.MathJax = {
  tex: {
    inlineMath: [ ['[latex]','[/latex]']],
processEscapes: true,
  },
  svg: {
    fontCache: 'global'
  }
};
</script>
<script type="text/javascript" id="MathJax-script" defer
  src="/mathjax/es5/tex-svg.js">
</script>

Konten Dinamis via Ajax 

Setelah konten via ajax selesai diload, jalankan script berikut :

MathJax.typesetPromise().then(() => {
// modify the DOM here
MathJax.typesetPromise();
}).catch((err) => console.log(err.message));

Ukuran Huruf 

Untuk mengubah ukuran huruf MathJax, dapat menggunakan CSS :

.MathJax {
  font-size: 1.3em;
}

Instalasi : Pemeriksaan Kemiripan Persamaan Matematika

MIaS

MIaS merupakan subsistem yang digunakan untuk memeriksa kemiripan persamaan baik itu matematika, kimia ataupun fisika.

Berikut adalah langkah langkah untuk menginstall MIaS.

cd mias/
./install.sh

Kemudian beberapa konfigurasi berikut di edit application/config.php

$config['webmias_url']                               = $config['site_protocol']."://".$config['site_domain'].":8080/WebMIaS-1.6.6-4.10.4-SNAPS$
$config['cli_mias_url']                              = $config['site_protocol']."://".$config['site_domain']."/indexing/cliMias";
$config['latex2mathml_url']                          = $config['site_protocol']."://".$config['site_domain']."/indexing/latex2MathML";
$config['indexed_formula_course_arr']                = [4] ;// [4,7,9,14,37]; //MAD, MAA, Fisika, Numerik
$config['tampilkan_kemiripan_di_kumpulan_soal']      = 0 ;

Latex2MathML

cd application/bin/Latex2MathML/
mvn clean install

Instalasi : Supervisor

Mac

/usr/local/etc/supervisord.ini


/usr/local/etc/supervisor.d/elasticsearch.ini

/usr/local/etc/supervisor.d/searchapi.ini

/usr/local/etc/supervisor.d/indexer.ini

Instalasi : Mac OS

Status : Draft

brew cask install mactex

Jika koneksi lambat, disarankan mendownload paket MacTex melalui torrent.

brew install python3
brew tap homebrew/cask
brew cask install phantomjs
brew install imagemagick
brew install cairo
brew install p7zip
easy_install pip

cd banksoal/
pip install -r requirements.txt
pip3 install -r requirements.txt


install PIL 1.1.7 [2]
install pdftk [3]
install pgAdmin [4]


PHP-FPM

Jika Anda mendaptkan error, seperti berikut ketika proses konversi Latex ke Image di browser :

convert: FailedToExecuteCommand `'gs' -sstdout=%stderr -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r360x360' '-sOutputFile=/var/tmp/magick-424wzOPTYa4oUUs%d' '-f/var/tmp/magick-424b_MRRkTxfwQT' '-f/var/tmp/magick-4247LVcZCDEEICo'' (1) @ error/pdf.c/InvokePDFDelegate/290.

Maka tambahkan konfigurasi berikut di /usr/local/etc/php/7.1/php-fpm.d/www.conf (sesuaikan dengan versi PHP yang And gunakan) :

env[PATH] = /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Elasticsearch

Untuk memastikan konfigurasi Elasticsearch sudah benar, jalankan perintah berikut :

supervisord -c  /usr/local/etc/supervisord.ini

Dokumentasi : Pemeriksaan Kemiripan Persamaan Matematika

Status : Draft 

Pemeriksaan kemiripan persamaan matematika di sistem informasi bank soal, meminjman kekuatan dari MIaS [1].

Secara periodik, controller indexing/dumpNaskahAsXhtml dan  script banksoal/application/bin/indexingMath.sh harus dijalankan, agar proses pemeriksaan kemiripan persamaan matematika dapat berjalan sebagaimana mestinya.

Elasticsearch

Status : Draft

Untuk proses pencarian teks, gambar dan persamaan matematika Bank Soal menggunakan elasticsearch [1].

Konfigurasi Elasticsearch 

Ketika menggunakan settingan default, terkadang, query ke soal Kimia terjadi error berikut :

Caused by: org.apache.lucene.search.BooleanQuery$TooManyClauses: maxClauseCount is set to 1024

Ketika menaikkan nilai indices.query.bool.max_clause_count di banksoal//elasticsearch/elasticsearch- 5.0.0/config/elasticsearch.yml menjadi 10000

indices.query.bool.max_clause_count: 10000

Alhamdulillah, error nya lenyap.
