glue 1.4.0 Unreleased

  • .envir = NULL is now supported and is equivalent to passing .envir = emptyenv() (#140)

  • New glue_safe() and glue_data_safe() functions, safer versions of glue() that do not execute code, only look up values (using get()). These alternatives are useful for things like shiny applications where you do not have control of the input for your glue expressions. (#140)

  • Fixed memory access issue and memory leaks found by valgrind.

glue 1.3.0 2018-07-17

Breaking changes

Features

Bugfixes and minor changes

  • Glue now throws an informative error message when it cannot interpolate a function into a string (#114, @haleyjeppson & @ijlyttle).

  • Glue now evaluates unnamed arguments lazily with delayedAssign(), so there is no performance cost if an argument is not used. (#83, @egnha).

  • Fixed a bug where names in the assigned expression of an interpolation variable would conflict with the name of the variable itself (#89, @egnha).

  • Do not drop the glue class when subsetting (#66).

  • Fix glue() and collapse() always return UTF-8 encoded strings (#81, @dpprdan)

glue 1.2.0 2017-10-29

  • 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 vignette("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.

glue 1.1.1 2017-06-21

  • Another fix for PROTECT / REPROTECT found by the rchk static analyzer.

glue 1.1.0 2017-06-13

  • 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).

glue 0.0.0.9000 Unreleased

  • Fix glue() to admit . as an embedded expression in a string (#15, @egnha).

  • Added a NEWS.md file to track changes to the package.
