A consistent, flexible and easy to use tool to parse and convert strings into cases like snake or camel among others.
News
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, anyting that mateches 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
Introduced to_swap_case(), which is also available in to_any_case() via
case = "swap" or case = "flip"
snakecase 0.8.3.1
abbreviations work now also in conversions to lower- and upper camel case.
snakecase 0.8.3

snakecase 0.7.1
CRAN update
for changes see V 0.7.0
additionally fixed obvious bug and forwarded to_xxx_case args to to_any_case

snakecase 0.5.0
CRAN update
Changes since last CRAN submission include:
string transliteration via updated replace_special_character argument
some new cases: "none", "mixed", "upper_lower", "lower_upper"
aliases: "all_caps", "lower_camel", "upper_camel"
different parsing options
several bugfixes
improved internal testing
internal modularisation
snakecase 0.4.0.9016
case == "none" works now with preprocess.
snakecase 0.4.0.9015
fixed bug so that case = upper_lower no also works for NA's.
snakecase 0.4.0.9014
added shortcutfunctions to_mixed_case(), to_lower_upper_case() and to_upper_lower_case().
snakecase 0.4.0.9013
Implemented two further parsing options:
3: parses the first UPPER letter group like parsing option 2 and the rest like option 1
4: parses the first UPPERlowercase letter group like parsingoption 1 and the rest like option 2
snakecase 0.4.0.9012
bug fix in devversion: 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 testcases 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 modularised a lot, which makes it easier
to maintain and introduce more highlevel features in the future
added integrated tests via appveyor on windows
added badges for cran status and codecoverage 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.
