## Project history and usage

dspdfviewer is Danny Edel's dual-screen PDF presenter for LaTeX Beamer talks, especially PDFs produced with Beamer's notes-on-second-screen layout.

### Project history

The README describes a deliberately narrow tool: split a Beamer-generated PDF into left and right halves and render the audience and speaker-note views on separate screens. The public GitHub release history shows the mature 1.13 through 1.15 line active in 2015 and 2016.

Version 1.14, published on 2015-12-01, was a notable portability release adding Windows, Qt5, and translation support. The final published GitHub release in the observed series, 1.15.1, followed on 2016-09-13 as a bugfix release for 1.15.

### Adoption history

dspdfviewer spread through academic and LaTeX presentation workflows rather than a broad desktop-app audience. It is packaged by Homebrew, Debian, Ubuntu, and MacPorts, which matches the needs of conference speakers and TeX users on Unix-like systems.

Homebrew analytics showed 610 installs over the preceding 365 days during this batch, unusually healthy for a small, old presenter utility.

### How it is used

The usual workflow is to build a LaTeX Beamer PDF with speaker notes, then run dspdfviewer on the resulting PDF. The README documents navigation keys, screen swapping, blanking the audience screen, and a `-f` mode for using ordinary PDFs.

### Why package nerds care

dspdfviewer matters to package nerds because it is a compact domain-specific GUI that survives through distro packaging: it solves one Beamer/presenter workflow well, has stable old releases, and depends on desktop PDF/Qt plumbing that package maintainers keep integrating long after upstream release activity slows.

### Timeline

- 2015-08-01: v1.13 was published in the GitHub release history.
- 2015-12-01: v1.14 was published with Windows, Qt5, and translation support.
- 2016-04-05: v1.15 was published.
- 2016-09-13: v1.15.1 was published as a bugfix release for v1.15.
- 2026 batch check: Homebrew still packaged v1.15.1 and showed 610 installs over the preceding 365 days.

### Related projects

- LaTeX Beamer is the presentation system whose notes-on-second-screen output dspdfviewer targets.
- Qt is the desktop toolkit family highlighted by the v1.14 release notes.
- General PDF viewers overlap for ordinary slides, but dspdfviewer is specialized around presenter notes and dual-screen splitting.
