Active software projects

Most of my active personal software projects are in one way or another related to my activities in the field of church music (composition, typesetting, research).

1. Web apps

• Church Calendar API

  My Ruby gem calendarium-romanum computes Roman Catholic liturgical calendar. The API uses it to make calendar data available online.

• E-Antiphonal

  Web application proxying another web (Czech Liturgy of the Hours on-line) and extending it's content with my musical settings of the rendered texts - thus turning a "breviary" in an "antiphonal".

2. Text processing tools

• gly

  Gregorio, a de facto standard tool for gregorian chant typesetting, has an ugly and impractical input format. Gly translates a more convenient input format to the canonical one.

• grely

  Translates Gregorio scores to Lilypond. Leverages a PEG parser of Gregorio input format.

• pslm

  Part of my typesetting toolbox: automates pointing of psalm texts for various chant tunes.

Inactive software projects

• Budebylo

  A small events calendar application for a local scouts' group in Kladno. (1 page of public frontend + administration interface; PHP+MySQL; in use since 2008; non-free, closed-source)

• freeVikings

  Attempt to make a free clone of the famous Lost Vikings. Developed 2004-2009.

  A bit of vanity: here might be the oldest (or at least the oldest publicly available) bit of Ruby code written in the Czech Republic. If you happen to know an older one, please e-mail me.

Websites

• In adiutorium :: http://www.inadiutorium.cz

  Complete musical settings of the Czech translation of Catholic Divine Office + a comprehensive collection of information concerning other existing musical settings.

Interests

• liturgy and liturgical studies
• Catholic theology in general
• music (singing, playing, researching)
