Testing patch to glyphFont() [Bug 18787]

[hturner]

In #68 (comment) there is a link to a fork of the R source code with updates to ensure glyphFont() only produces a single font description, giving warnings if arguments are longer than one.

The next steps are to run standard checks on the patch and perform visual regression testing.

Get and apply the patch

You can get a patch file of the difference between the proposed solution and the latest R source by visiting the following URL

https://github.com/r-devel/r-svn/compare/main...szimmer:r-svn:PR18787.diff

Save the content of the HTML page as PR18787.diff.

Checkout the latest version of the R sources, e.g. by Setting up the R Dev Container in GitHub Codespaces and following steps 1-3 of the Building R tutorial.

Apply the patch with

svn patch <path/to/patch>/PR18787.diff

(if you are in the R Dev Container, you will need to upload the patch file into the workspace first).

Build R and run a full check

Build R, e.g. by following steps 4-6 of the Building R tutorial.

Run a full check by running

make check-all

in the build directory

Run visual regression tests
