convertxlsform 0.3.0

A complete rewrite. The package writes Word and PDF paper versions of an XLSForm through a new API, a terminal interface and one document model that both outputs share.

New features

• convertxlsform() writes a Word document (.docx) by default. format = "pdf" or format = c("docx", "pdf") also writes a PDF. The output location, format and overwrite rules follow from the arguments, and the function returns the paths invisibly.
• PDF output converts the Word document with LibreOffice. Microsoft Word is used through the doconv package when LibreOffice is not found. docx_to_pdf() and has_libreoffice() are exported.
• cli() runs a conversion from a terminal, for example Rscript -e 'convertxlsform::cli()' form.xlsx --format pdf. Scripts can use quit(status = convertxlsform::cli()) to get the exit status.
• xlsform_outline() returns the numbered form as a data frame, for checking a form before conversion.
• xlsform_languages() lists the languages in a form and marks the default.
• Language columns are read from label::English (en), label::en and label::English. The lang argument accepts a code, a name or the full suffix. A blank translated cell falls back to the plain column, then to the default language. Headers with a common language name only, such as label::French, also match their ISO 639-1 code (lang = "fr").
• Skip logic, constraints and choice filters are written in plain language. Expressions that cannot be read are shown as written.
• Connective phrases such as “Ask if” come from built-in English and French tables. The strings option replaces any of them for another language.
• Paper layouts for each question type: single and multiple choice, rank, long lists as code boxes, write-in boxes, numeric, date and time formats, geographic and media questions, and acknowledgments.
• Groups and repeat groups, with nested numbering (nested_serial_numbers) and blank copies of repeats (repeat_copies).
• Question images are scaled to at most 2 inches tall, and choice images to at most 0.6 inches. A missing media or choice file triggers one combined warning, and a missing image prints a placeholder.
• Complex-script fonts are chosen from the text for Bengali, Arabic, Devanagari and Ethiopic. The font_family_cs option overrides the choice.
• Page size, orientation, margins (up to 2 inches), fonts, a reference template, title, and switches for hints, constraints, relevants, choice codes, variable names and hidden rows.
• Bundled examples: inst/extdata/multilang (multilingual, with an external choice list and images) and inst/extdata/all_types (every question type and feature the package renders).

Changes from 0.2.1

• Arguments are renamed: xlsform_path is now xlsform, output_docx is now output, selected_language is now lang, and number_questions is now nested_serial_numbers. The 0.2.1 names are not accepted.
• HTML tags in labels are stripped. Emphasis in Markdown is rendered.
• Imports are reduced to cli, flextable, magrittr, officer, readxl, rlang and zip, plus base packages (stats, tools, utils). optparse is no longer used, and the command line is parsed by cli().

Known issues

• PDF output can show blank text for Bengali and other complex scripts when LibreOffice cannot find a suitable font on the machine. The Word document is correct. A fix is planned for 0.4.0.
