Install Required LaTeX Packages

Proactively installs all LaTeX packages needed by arframe's PDF backend. Checks which packages are missing, then installs them using a three-tier strategy:

Usage

fr_install_latex_deps(repository = NULL)

Arguments

repository

Character or NULL. CTAN mirror URL for the system tlmgr fallback (Tier 2). Default NULL uses "https://mirror.ctan.org/systems/texlive/tlnet". Set this for corporate networks that require a specific mirror.

Value

Invisible NULL. Called for its side effect of installing packages.

Details

1. TinyTeX — if tinytex::is_tinytex() is TRUE, uses tinytex::tlmgr_install() (user-writable, auto-updates).

2. System tlmgr — if TinyTeX fails or is absent but system tlmgr is on PATH, calls tlmgr --repository <mirror> install directly. This handles corporate RHEL/Ubuntu systems with system TeX Live.

3. Error — if no TeX distribution is found, provides install instructions.

Missing packages are detected via tinytex::check_installed() when available, falling back to kpsewhich on the command line.
