snakecase 0.11.0 (25.05.19)

Changes in 0.10.0 and 0.10.0.9000

New functionality:

• abbreviations: Abbreviations are now …
  • … matched case-insensitive inside of groups of connected lower/upper case sequences.
  • … consistently formatted according to the supplied case.
  • … formatted exactly as supplied for the cases title, mixed, lower and upper camel.
  • … protected from the parsing. This means that
    • special characters in abbreviations don’t need to be taken care of anymore. The formatting of digits or special characters like hyphens, colons etc. will be formatted as specified.
• parsing_option:
  • new parsing option 3 parses “SOmeNIceSTUFf”.
  • parsing options starting with a minus (-1, -2, -3) interprete non-alphanumeric characters as word boundaries. E.g. “This.text” will stay “This.text” in upper camel case.
• cases
  • title: New case which should be especially useful for automatic generation of proper labels within graphics or business reports. Builds up on sentence case which is wrapped within tools::toTitleCase().
  • random: New case, which will randomly convert letters into upper or lower case.
• numerals: new alignment option "tight" which allows to suppress all underscores between numerals and letters.
• sep_out: sep_out gets proper vectorization. In case of length(sep_out) > 1 differing substrings are connected by the (possibly) differing elements of sep_out. Therefore, sep_out gets accordingly shortened or the last element of sep_out gets recycled to match the number of needed separators for each element of string.
• UTF8 Conversion: Input is now always converted to UTF-8 and returned as UTF8. Also the transliterations argument is now aware of non-UTF8 encoded input.

Infrastructure:

• CII best practices badge: Achieved the criteria for the best practices badge. Current status is under https://bestpractices.coreinfrastructure.org/de/projects/2475
  
• R Version: Increase from 3.1 to 3.2 regarding the usage of tools::toTitleCase() inside to_title_case().
  
• Vignettes: The blog article “Introducing the snakecase package” was added as a vignette.
  
• Documentation: The readme, the examples and the function documentation were updated according to the new functionality.
• Resolve CRAN notes:
  • Tests: Skip to_any_case() tests (janitor-pkg-tests, transliterations and complex strings) when platform charset is not UTF-8 to resolve CRAN notification regarding character encoding.
  • Vignettes: Build the package with new version of knitr to resolve CRAN notification regarding vignette encoding.

snakecase 0.10.0.9000

• cases: Title case now builds up on sentence case (instead of parsed_case).
• abbreviations: Abbreviations are now
  • matched case-insensitive
  • formatted as they are supplied for title-, upper-camel-, lower-camel- and mixed case. Apart of that abbreviations are still formatted according to the specified case.
    • protected from the parsing. This means that
    • special characters in abbreviations don’t need to be excluded via a regex in the sep_in parameter
    • the formatting of digits or special characters like hyphens, colons etc. will be formatted as specified.
• parsing_option:
  • new parsing option 3 implemented which parses “SOmeNIceSTUFf”.
  • each parsing option can now be prefixed by a minus (-1, -2, -3). In this way

snakecase 0.10.0 (16.05.19)

• CRAN release

snakecase 0.9.2.9002

• numerals: new alignment option "tight" which allows to suppress all underscores between numerals and letters.
• improved speed: time of internal parsing could be reduced about a factor of ten, due to some vapply() replacements.
• UTF8 Conversion: Input is now always converted to UTF-8 and returned as UTF8. Also the transliterations argument is now aware of non-UTF8 encoded input.
• Improved vecorisation of sep_out: sep_out now behaves better for vector input (length > 1). Instead of returning different strings, the return is now one string, which uses separators according to the supplied order. When length(sep_out) > 1, the last element of sep_out gets recycled.
• random_case: added to_random_case(), which will randomly convert letters into upper or lower case.
• title_case: added to_title_case(), which is basically to_parsed_case() with sep_out = " " wrapped within tools::toTitleCase() and should be especially useful for proper labels within graphics or business reports.
• increase R Version dependency from 3.1 up to 3.2 regarding the usage of tools::toTitleCase().
• skip to_any_case() tests (janitor-pkg-tests, transliterations and complex strings) when platform charset is not UTF-8.

snakecase 0.9.2

• cases: added to_sentence_case() (same as snake, but first letter is uppercase and default sep_out is space).
• numerals: added numerals argument to all caseconverters including to_any_case() to format the alignment of digits (middle, left,right, asis). Therefore parsing_option nr 4 might be removed in later releases, as it is the same as parsing_option = 1 and numerals = "asis".
• transliterations: When named character elements are supplied as part of transliterations, anything that matches the name is replaced by the corresponding value.
• attributes are now preserved (not only names as before)

snakecase 0.9.1

• CRAN release
• Change default sep_in from NULL to "[^[:alnum:]]". This will make it easier for beginners and in general also faster to modify cases from names like names(iris). Updated the regarding sections in the vignette and readme.

snakecase 0.9.0

• CRAN release

• Changes since last update:

  • parsing_options:
    • old parsing_options 3 and 4 are replaced now by new
      • parsing_option 3, which suppresses case conversion around alpha numerics
      • parsing_option 4, which introduces less formatting of numerals in the output, and leaves them very close to the way that they appeared in the input strings.
  • abbreviations:
    • they work now more consistent with cases like lower- and upper camel case
  • new converters:
    • to_swap_case() is new. Within to_any_case() this conversion can be called also via case = "flip".
  • removed deprecated arguments
    • replace_special_characters, which is now called transliterations
    • preprocess, which is now called sep_in
    • postprocess, which is now called sep_out
  • removed dependencies:
    • purrr and magrittr are not longer dependencies
    • stringr is the only dependency now (including stringi of course).

snakecase 0.8.4

snakecase 0.4.0.9012

bug fix in dev version: protect works now for beginning and end of substrings and not anymore only for complete substrings.

snakecase 0.4.0.9011

Fix bug for character(0) in combination with postprocess

snakecase 0.4.0.9010

Input of replace special character is now a character vector. It’s entries have to be elements of stringi::stri_trans_list() or names of the transliteration dictionary list, which comes with this package. This update enables users to transliterate strings from different encodings, in a flexible way. For example UTF8 to Ascii, … .

snakecase 0.4.0.9009

• provided aliases "all_caps", "lower_camel" and "upper_camel" for "screaming_snake", "small_camel" and "big_camel".

snakecase 0.4.0.9008

• small bug fix for upper_lower/lower_upper regarding the behaviour for the combination of preprocess and protect (similar to an earlier bug in the camel cases).

snakecase 0.4.0.9007

• small bug fix for behaviour of upper_lower/lower_upper. Now substrings with without alphabetical characters are ignored.

snakecase 0.4.0.9006

• new implemented cases: “none”, “mixed”, “upper_lower”, “lower_upper”.

snakecase 0.4.0.9005

• empty_fill runs again in the end, before the pre and postprocess
• fixed bug: to_any_case("r.aStudio", protect = "a", postprocess = "-", case = "big_camel") will now correctly return “R-.AStudio” (so the protection will be triggered by the input and not by the output). In contrast protect = A will yield in unprotected output (-A-)

snakecase 0.4.0.9004

• empty_fill runs now at the beginning of to any case function (after the first parsing) and a second parsing is introduced in case anything is filled.

snakecase 0.4.0.9003

• fixed bug in camelcases, for letters after protected symbols (usually one wouldn’t protect in these cases anyway…)

snakecase 0.4.0.9002

• implemented check_design_rule() (not exported)
• resolved bugs in other design options (also deleted one which is not valid for screaming snake case)

snakecase 0.4.0.9001

• included several parsingoptions for to_any_case().
  1: “RRRStudio” -> “RRR_Studio” stays as default
  2: “RRRStudio -> RRRS_tudio”
  any other number will suppress the parsing (only spaces will be converted into "_")

snakecase 0.4.0.9000

• This is the (stable) development version now. You can find snakecase on cran here

snakecase 0.4.0

• CRAN submission

snakecase 0.3.5.3

• changed order of the customizing arguments of to_any_case()

snakecase 0.3.5.2

• fixed bug for combination of protect and postprocess. Therefore clarified and rewrote the internal order of to_any_case()
• resolved all internal build warnings and notes

snakecase 0.3.5.1

• fixed bug in replace_special_characters combined with screaming snake case.

snakecase 0.3.5

• any local special characters are now supported.
• added 2 arguments to to_any_case(): empty_fill, which allows to fill strings matching to "" with the supplied string. unique_sep adds an integer suffix separated with the supplied string, when not NULL.
• fixed a bug in to_snake_case_internal(). groups of digits are not separated in between anymore.
• digits that are not direct next to each other, will be split via "_" in both camel case versions. This is a meaningful exception. Otherwise information would be lost and also the consistency rules in the readme wouldn’t hold in this case.

snakecase 0.3.4

• any_case() is now vectorised over pre-/postprocess, pre-/postfix for all case arguments
• introduces protect as (vectorised) argument to to_any_case(). it accepts regular expressions and cleans "_" or whatever the preprocessing did, between matches.
• some more tests, documentation and fixes.

snakecase 0.3.3

• introduced case = “parsed” in to_any_case()
• introduced to_parsed_case()

snakecase 0.3.2

• finished vignette (title: Caseconverters) and replaced the usage part in readme with it.
• changed behaviour in snake_case_internal to always treat whitespaces as underscores. for whitespaces in output postprocess = " " is recommended.

snakecase 0.3.1

• started testing to_any_case and removed a bug.
• added vignette

snakecase 0.3.0

• supports behaviour for german umlauts on all platforms
• introduced internal function to_snake_case_internal() which does the preprocessing and simplifies all other functions (especially to_any_case()) a little bit.
• introduced to_screaming_snake_case()
• added arguments prefix, postfix and replace_special_characters to to_any_case().
• completely renewed readme
• updated tests and highly modularized all tests. (just to_any_case lacks some tests now and in general more examples test cases have to be written)

snakecase 0.2.2

• introduced to_any_case() (all functionality and documentation provided, but implementation has to be cleaned and also tests have to be written)

snakecase 0.2.1

• fixed bug: to_snake_case_dev(c("ssRRss")) returns now ss_r_rss instead of"ss_r_r_ss"
• to_snake_case() now treats only spaces like underscores now (not dots anymore)
• functionality to treat different stuff like dots will be added via a new function:
  to_any_case(), which will wrap the other three and will have pre- and postprocess arguments

snakecase 0.2.0

• renamed the single input parameters consistent to string (without deprecating the old name before, since the package was in early dev-stage anyway).
• started a to develop and implement consistent logic (which still has to be better documented in the readme)
• introduced tests for more hard coded examples and the logic behind it (still more hardcoded examples and a third part of the logic have to be tested)
• internal logic has been simplified and modularized a lot, which makes it easier to maintain and introduce more high-level features in the future
• added integrated tests via AppVeyor on windows
• added badges for cran status and code coverage to readme

snakecase 0.1.0

• Introduced to_snake_case() which converts strings to snake_case.
• added functions to_small_camel_case() and to_big_camel_case() which internally build up on to_snake_case() and convert to the appropriate target case.
• added basic hard coded tests
• added integrated tests on linux via travis.ci
