# glue 1.3.0
## Breaking changes
* The `evaluate()` function has been removed. Changes elsewhere in glue made
the implementation trivial so it was removed for clarities sake. Previous
uses can be replaced by `eval(parse(text = text), envir)`.
* `collapse()` has been renamed to `glue_collapse()` to avoid namespace
collisions with `dplyr::collapse()`.
## Features
* `compare.glue()` was added, to make it easier to use glue objects in
`testthat::expect_equal()` statements.
* `glue_col()` and `glue_data_col()` functions added to display strings with
color.
## Bugfixes and minor changes
* 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
* 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
* Another fix for PROTECT / REPROTECT found by the rchk static analyzer.
# glue 1.1.0
* 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
* Fix `glue()` to admit `.` as an embedded expression in a string (#15, @egnha).
* Added a `NEWS.md` file to track changes to the package.
