The implementation has been tweaked to be slightly faster in most cases.
glue() now has a .transformer argument, which allows you to use custom logic on how to evaluate the code within glue blocks. See vignettes("transformers") for more details and example transformer functions.
glue() now returns NA if any of the results are NA and .na is NULL. Otherwise NA values are replaced by the value of .na.
trim() to use the trimming logic from glue is now exported.
glue_sql() and glue_data_sql() functions added to make constructing SQL statements with glue safer and easier.
glue() is now easier to use when used within helper functions such as lapply.
Fix when last expression in glue() is NULL.
Fix for PROTECT errors when resizing output strings.
glue() always returns ‘UTF-8’ strings, converting inputs if in other encodings if needed.
to() and to_data() have been removed.
glue() and glue_data() can now take alternative delimiters to { and }. This is useful if you are writing to a format that uses a lot of braces, such as LaTeX. (#23)
collapse() now returns 0 length output if given 0 length input (#28).
Fix glue() to admit . as an embedded expression in a string (#15, @egnha).
Added a NEWS.md file to track changes to the package.
