# `unitizer` NEWS

## v1.4.24

* Fix tests for changes to `structure()` in r90216.
* Fix incorrect install.packages(type='src') uses in tests.

## v1.4.23

* Fix CRAN M1 Mac additional issues related to test failing because we used a
  library path in un-normalized form for temp test packages, but the unload
  namespace mechanism uses the normalized form to de-register cached rdb files.
  Seems this was caused by a MacOS change rather than R, but not 100% sure.

## v1.4.22

* Fix unnamed arguments error in a call to `deparse` that manifested with
  improvements changes in r-devel.
* Fix bad `all.equal` method NAMESPACE entries (h/t @MichaelChirico), see
  [source issue](https://github.com/r-lib/roxygen2/issues/1587) for details.

## v1.4.21

* Suppress test caused to fail by checks added to `parent.env<-` in r-devel r86545.

## v1.4.20

* Add explicit alias for `fansi-package` now that it is no longer 
  auto-generated by roxgen2 from the [`@docType package` directive](https://github.com/r-lib/roxygen2/issues/1491).

## v1.4.19

* [#293](https://github.com/brodieG/unitizer/issues/293): Output all failed
  tests in non-interactive mode, instead of just the first one.
* [#292](https://github.com/brodieG/unitizer/issues/292): Clarify warnings about
  stderr in transcript mode.
* Fully unhook the evaluation environment chain prior to storing unitizers.
  Previously only the portions of the chain part of the unitizer was unhooked,
  but with some tests it becomes possible to capture environments created during
  the `pre` expression evaluations.  This could cause warnings about package
  environments being unavailable on reload of RDSes.

## v1.4.18

* [#289](https://github.com/brodieG/unitizer/issues/289): Better document
  pitfalls of non-ASCII in e.g. literals in tests.  Related: we no longer
  attempt to do a parse/deparse round trip when displaying recorded test
  expressions as the round trip could fail in some cases.
* [#288](https://github.com/brodieG/unitizer/issues/288): Prevent upgrade prompt
  in non-interactive mode interrupting result display (regression introduced in
  1.4.15).
* [#286](https://github.com/brodieG/unitizer/issues/286): Add a "transcript"
  mode where test output can better be interpreted as a log, intended
  non-interactive mode.
* [#272](https://github.com/brodieG/unitizer/issues/272): Highlight silently
  emitted conditions in tests that have otherwise no other output.
* [#252](https://github.com/brodieG/unitizer/issues/252),
  [#253](https://github.com/brodieG/unitizer/issues/252): Better documentation
  of feature incompatibility with `devtools::load_all`, and more graceful
  recovery from failures caused by the incompatibility.  This only affects
  `unitizer` sessions run with package search path management enabled (h/t
  @blset).
* [#247](https://github.com/brodieG/unitizer/issues/247): Disallow running
  `unitizer` without first attaching it to the search path.
* [#245](https://github.com/brodieG/unitizer/issues/245): Fix re-run bookmarking
  when reviewing multiple unitizers with `unitize_dir`.

## v1.4.16-17

* [#285](https://github.com/brodieG/unitizer/issues/285): Relax condition call
* [#284](https://github.com/brodieG/unitizer/issues/284): Handle CTRL+C
  interrupts while multi-line editing.
* [#283](https://github.com/brodieG/unitizer/issues/283): Multi-unitizer upgrade
  regression introduced in 1.4.15.
* Address CRAN failures due to path inconsistencies on Windows machines.
* [#279](https://github.com/brodieG/unitizer/issues/279): Multi-line input
  parsing works in non-English locales.

## v1.4.15.9000

Non-CRAN release to fix test issues under `covr` and on older R versions.

## v1.4.15

* Test suite switched to `aammrtf`, removing suggests dependency to `testthat`.
* Upgrade process modified so that old `unitizer` that pass tests are not
  required to be upgraded.
* `show.progress` parameter added to control chattiness of progress updates.
* Invalid `unitizers` now prevent review of valid `unitizers`.  Fix the invalid
  `unitizers`, or remove them from the review list (e.g. by moving them out of
  the primary `unitizer` directory).
* `review` exposes `use.diff` and `show.progress` parameters.
* [#278](https://github.com/brodieG/unitizer/issues/278): Show more context when
  returning to a test via browser or on re-evaluation.
* [#277](https://github.com/brodieG/unitizer/issues/277): Handle CTRL+C
  interrupts so they do not kill the `unitizer` session (h/t
  [@milesmcbain](https://milesmcbain.micro.blog/2021/06/10/debugging-cantrip-from.html)).

## v1.4.13-14

* `unitizer` no longer directly accesses `.Traceback` to set traces in
  interactive sessions.  Instead, `traceback()` and `.traceback()` are masked
  at the interactive prompt.

## v1.4.11-12

* [#248](https://github.com/brodieG/unitizer/issues/248): Ensure vignettes can
  be tested with `tools::testInstalledPackage`.

  [#251](https://github.com/brodieG/unitizer/issues/251),
  [#254](https://github.com/brodieG/unitizer/issues/254): Comment parsing
  improvements (h/t
  [@blset](https://github.com/brodieG/unitizer/issues/created_by/blset),
  [@kalibera](https://github.com/kalibera/))
* [#263](https://github.com/brodieG/unitizer/issues/263): Clarify documentation
  about potential state management issuess.  This includes renaming
  "recommended" state management mode (see `?unitizerState`) to "suggested"
  ("recommended" still works).
* [#268](https://github.com/brodieG/unitizer/issues/268): `options(warn=2)` now
  works at the `unitizer` prompt in interactive mode.
* [#265](https://github.com/brodieG/unitizer/issues/265): Bad vignette links in
  README (h/t [@moodymudskipper](https://github.com/moodymudskipper)).
* [#260](https://github.com/brodieG/unitizer/issues/260): Remove old test error
  display code.
* [#246](https://github.com/brodieG/unitizer/issues/246),
  [#243](https://github.com/brodieG/unitizer/issues/243): Assorted documentation
  updates.
  [#254](https://github.com/brodieG/unitizer/issues/254): Comment parsing.
* Fix `sprintf` unused argument errors in new versions of r-devel (h/t
  [@kalibera](https://github.com/kalibera/)).
* `stringsAsFactors` rose from the grave; we put it back.

## v1.4.10

* Banish ghosts of `stringsAsFactors`.

## v1.4.9

* [#262](https://github.com/brodieG/unitizer/issues/262) Interactive prompt
  slowness caused by recent R changes to `showConnections()`.

  explicitly saved in serialization version 2 for backwards compatibility.
* [#244](https://github.com/brodieG/unitizer/issues/244) Squash all partial
  match warnings that `unitizer` emitted under `options(warnPartialMatch*)`.
* Tests explicitly set `stringsAsFactors=TRUE` so they don't fail with the
  anticipated changed for R4.0.
* Adds the 'unitizer.restarts.ok' option to suppress warnings about being run
  within `withRestart` blocks.

## v1.4.8

* `install.packages` calls in tests now use a temporary folder for library.

## v1.4.7

* Set `RNGversion()` in internal tests due to changes to R sampling mechanism.

* Can now pre-load objects before unitizing; `unitize_dir` and `unitize` by
  default auto-preload files in subdir 'helper'
* Renamed arg `env.clean` to `par.env` (technically API breaking, but since no
  one is using this package yet...)
* Many usability fixes (#48, #68, #82, #83), and improved text display

  (Issue #34)
* Text handling generally improved (better wrapping, etc. Issue #38)
* Parsing speed improved (Issue #15)
* Got rid of `get*` functions, instead, access test details with `.NEW`/`.REF`
  (Issue #29)
* Implemented `editFunNames` to allow user to modify stored calls in `unitizer`
  so that tests can be re-used even if function names are changed

## v0.6.5

## v0.6.4

### Improvements:

* Comment parsing faster (issue #15)

### Bugfixes:

* Reference section logic improved (assume fixes #36 until there is evidence
  against)

  (issue #21)
* Test navigation mechanism improved (issue #26)
    * Typing R at the unitizer prompt now allows you to review all tests
    * You can skip ahead too

* New vignette "Reproducible Tests" discusses the above features

### Bugfixes:

* Expressions printed as tests evaluated now truncated corretly (issue #4)
* Incorrect displaying/hiding of ignored tests in some circumstances fixed

### Other Improvements:
