Changelog

mrggsave now requires R >= 4.1 (#58).
When using R 4.5.0 or greater, plots saved via the pdf() device are now written without timestamps or author information by default. Global options are included to enable the timestamp or to override the mrggsave author default (#59, #64).
Cairo-based pdf output can be generated by passing dev = "CairoPDF", which invokes the Cairo::CairoPDF() device; the output file is given a .pdf extension. Any formal argument of Cairo::CairoPDF() can be passed through, but “back-end” arguments cannot. Global options are exposed to let users restore timestamps or override the mrggsave author default (#64).

Drawing-related functionality has been removed: the mrggdraw() and draw_newpage() functions are gone, as is the draw argument to mrggsave(). This functionality carried extra complexity, but is not directly related to the core purpose of mrggsave (#67, #68).
The mrggpage() function has been removed; use patchwork to arrange plots instead (#66).
The .save argument has been dropped from mrgglabel(); it was always passed as FALSE and could not be set by the user (#67).

Fixed bug when using a tag to name plots when a full path to script was provided (#53).

Fixed a bug where an error was encountered when trying to save a list of plots with no annotation (labeller = NULL) (#49).
Updates for compatibility with glue 1.8.0 (#44).

New option mrggsave.res to set default resolution for devices like png() and jpeg() (#42).

mrggsave() gains an argument called path.type which controls how the path to the figure file is rendered in the figure annotation; the default is "proj", which will render the path relative to an RStudio project file, if it can be found; alternatives are "none" and "raw"; path.type can be set through the mrggsave.path.type option (#38, #39).
Unit tests were numbered and user stories added to build validation documents (#35, #37).

Refactored how the glue() environment was captured so that string interpolation is more robust when attempted in unique environments (for example inside function calls) (#26)

Calling the cairo_pdf device now allows multiple plots to be written to the same file (#21)

Revert behavior where named list automatically uses the names for output file names #18
Fix typo in mrggsave:::output_file_sep() title

The default separator when auto-constructing file names is changed from underscore to hyphen; this is a breaking change that will result in different output filenames if users were using tag #2
Use the unexported (but documented) function mrggsave:::output_file_sep() to globally change the output file separator character #12
The prefix argument to mrggsave_common() now defaults to NULL; the Source graphic: annotation defaults to only showing the base file name of the plot

If a named list of plots is passed (checked via rlang::is_named), use_names will be set to TRUE and names used for output filename #8
Passing a list of plots generated by named_plots will set use_names to TRUE and the names will be use for output file names #8
When a named list of plots is passed, the names are adjusted to remove spaces, periods and underscores when creating the output file stem; these characters are replaced with hyphens #8
mrggsave_common() now has a labeller argument; pass a function to create the annotation for the plot; pass NULL to save a plot with no annotation #8
named_plots() gains an argument called add_context; when TRUE, the context (usually the script name) will be pre-pended to the output file name; this argument is FALSE by default #8
Add option called mrggsave.file.tolower which, if set to TRUE will pass the file stem through base::tolower(), making it all lower case, regardless of how the stem was generated #8
Add ability to save to multiple devices on one function call; pass a character vector of devices or a comma-separated string as dev

Add support for the following devices: pdf, png, tiff, jpeg, eps, ps, bmp, svg (#13)
Add ability to save last plot when it was created with ggplot2 (see the mrggsave_last function); this gets the last plot via ggplot2::last_plot (#12)
Add ability to save a named list of plots; when the list is named and the use_names argument is invoked, plots will get written out to their own file names (#14)
Add method for handing ggsurvplot objects (#11)
Pass the file name through glue::glue once it is formed from either stem or tag (e.g. stem = "dv_pred_{runnumber}") (#15)
Add named_plots function to generate plot names (and eventually file names) from the code used to generate the plot (#14)
Add non-exported context function to set the output file name when using tag argument; context is set and is in effect via option until the context is changed or reset; use context_clear
Removed support for objects created with patchwork

Added ncol as a formal argument; when ncol > 1, we set arrange to TRUE
Added mrggpage function as a wrapper around gridExtra::arrangeGrob
Added mrggsave_list, which takes in a list of objects that are ready to label and to save without arrangement
Changed mrggdraw so that all it does is draw a plot or plots, possibly after arranging
mrggdraw now returns processed plots invisibly so that they may be passed into mrggsave
Added internal generic mrggsave_prep_object and methods so that plots of different types can be passed directly to mrggsave_common
Added mrggsave.gList for saving gList objects
When tag or stem are given as a vector, the vector is collapsed using _ as a separator first prior to forming any output file names
When a file name is formed from tag, a _ separator is automatically placed between script and the (possibly collapsed) tag value
Added support for gtable objects
Added a default mrggsave method that assumes the object is a grob
Added argument to mrggpage to allow a list of plots to be arranged across multiple pages; added methods for handling arrangelist objects coming out of gridExtra::marrangeGrob
