Release {styler} 1.7.0 (2022-03-13) · r-lib/styler

API changes

new R option styler.cache_root (defaulting to "styler") that determines the sub-directory under the {R.cache} cache directory that {styler} uses. Non-default caches won't be cleaned up by {styler}. We suggest "styler-perm" (also used by {precommit}).
stylerignore markers are now interpreted as regular expressions instead of comments that must match exactly. This allows to specify multiple markers in one regular expression for styler.ignore_start and styler.ignore_stop, e.g. to use markers for lintr and styler on the same line, you can use options(styler.ignore_start = "nolint start|styler: off":
```
# nolint start, styler: off
1 +1
# nolint end
# styler: on
```
As a consequence of this approach, the defaults for styler.ignore_start and styler.ignore_stop omit the # (#849).

{styler} can be ran via GitHub Actions using usethis::use_github_action("style") (#914).
added guarantee that styled code is parsable (#892).
Developers can now create style guides with indention characters other than spaces (#916).

Piped function without brackets substitute(x %>% y) don't get () added anymore for one level deep (not more yet, see #889), as this can change outcome of the code (#876).
.onLoad() method no longer broken with {cli} >= 3.1 (#893).
Function calls containing + should no longer give any error on styling when there are comments and line breaks under certain circumstances (#905).
rules that add tokens don't break stylerignore sequences anymore (#891).
Alignment detection respects stylerignore (#850).
Unaligned expressions with quoted key (e.g. c("x" = 2)) are now correctly detected (#881).
~ causes now indention, like +, -, | etc. (#902).
Warning: Unknown or uninitialised column: was fixed (#885).
function calls with unequal number of token on different lines are no longer deemed aligned if there are arbitrary spaces around the tokens on the lines with most tokens (#902).
if a line starts with EQ_SUB (=), the corresponding key is moved to that line too (#923).
ensure a trailing blank line also if the input is cached (#867).
Preserve trailing blank line in roxygen examples to simplify concatenation of examples (#880).
indenty_by is now also respected when curly braces are added to an if statement by {styler} (#915).
An error is now thrown on styling if input unicode characters can't be correctly parsed for Windows and R < 4.2 (#883).
styling of text does not error anymore when the R option OutDec is set to a non-default value (#912).

Remove dependency on {xfun} (#866).
Remove {glue} dependency that was only used by {touchstone} script and is declared as a dependency already in the respective action (#910).
Bump minimal R requirement to 3.4 in line with the tidyverse, which allowed to remove the dependency at {backports} and some exception handling.
rename default branch to main (#859).
the built package size has been reduced by ~50% by listing *-in_tree files in .Rbuildignore (#879).
Enable pre-commit.ci (#843).
use pre-commit via GitHub Actions (#872).
terminate running jobs on new push to save resources (#888).
Use the {touchstone} GitHub Action instead of the literal script (#889).
upgrade R CMD check Github Actions to use v2.
{styler} test are relaxed to not assume a specific error message on the wrong usage of _ (#929).
