Fix font package detection for fonts with spaces in names#479
Merged
Conversation
Font names with spaces (e.g., "Noto Emoji", "DejaVu Sans") now work correctly in automatic package installation. The font_ext() function replaces spaces with \s* regex pattern to match actual font files that lack spaces (e.g., NotoEmoji-Regular.ttf, DejaVuSans-Bold.ttf).

When R Markdown documents use fonts with spaces in their names (e.g., "Noto Emoji", "DejaVu Sans"), automatic package installation via
tinytex::parse_install()fails becausetlmgr searchcannot find the packages.Root Cause
The
font_ext()function generates search patterns that preserve spaces from the font name reported in LaTeX errors. When LaTeX reports "Font 'Noto Emoji' not found", the generated pattern is:Font files never have spaces in their names (
NotoEmoji-Regular.ttf,DejaVuSans-Bold.ttf), sotlmgr search --filefails to find matching packages.Fix
Spaces in font names are replaced with
\s*regex pattern inR/latex.R:665:This generates patterns like
Noto\s*Emoji(-(Bold|Italic|Regular).*)?[.](tfm|afm|mf|otf|ttf)that match actual font files.Tests were added in
tests/test-cran/test-latex.Rto verify both thefont_ext()function directly and the fulldetect_files()workflow for fonts with spaces.Fixes #478
