SUSTech Beamer Theme \setsource Fix
Problem
When filling main.tex from the standard slides-template, latexmk -xelatex fails with:
! Undefined control sequence.
l.23 \setsource{...}{...}
Also: \setdomains, \setpresenter, \setvenue. These are used by newer decks but NOT defined in the plain template version of beamerthemesustech.sty.
Root cause
The base beamerthemesustech.sty is ~60 lines, ending with \mode<all>. The extended version (shipped in the sustech-slides-template repository) continues to ~100+ lines with:
\paperfrom{venue}{year}— formats the source line\setsource{venue}{year}— calls\paperfrom\setdomains{...}— sets domain tags\setpresenter{name}— sets presenter name\setvenue{location}— sets venue location\titlemetaline— formats the title page bottom line
Fix
The extended macros ship in the sustech-slides-template repository at sustech-theme/beamerthemesustech.sty. After copying the template into your deck, replace beamerthemesustech.sty with the extended version.
If you already have a checkout of the repository:
cp "<TEMPLATE_DIR>/sustech-theme/beamerthemesustech.sty" \
"<TARGET>/slides-beamer/sustech-theme/beamerthemesustech.sty"
Otherwise clone it first, then copy:
git clone --depth 1 https://github.com/yhbcode000/sustech-slides-template.git <TEMPLATE_DIR>
cp "<TEMPLATE_DIR>/sustech-theme/beamerthemesustech.sty" \
"<TARGET>/slides-beamer/sustech-theme/beamerthemesustech.sty"
Do this BEFORE first compile. The beamerthemesustech-elements.sty and beamercolorthemesustech.sty files are identical between the repository template and the reference deck — only beamerthemesustech.sty carries the extended macros; when in doubt, copy the whole sustech-theme/ directory.
