In stringmagic: Character String Operations and Interpolation, Magic Edition

stringmagic 1.1.2

Hot fix

• make stringmagic compatible with R in [4.1.0; 4.1.2].

New features

• add argument .trigger to cat/message_magic_alias

stringmagic 1.1.1

Hot fix

• make stringmagic compatible with R < 4.1.0 by removing calls to ...names().

stringmagic 1.1.0

New functions

• add string_extract to extract patterns

• add string_split to split character strings

Improvements

• string_ops now uses ... to pass operations. This is backward compatible.

• string_clean: now the magic flag also expands the replacements:

x = "Hi Mary, how's John doing?"
from = "John"
to = "Kate"
string_clean(x, "m/{from} => {to}")
#> [1] "Hi Mary, how's Kate doing?"

• string_magic: add the comma flag to the enum operation. In that case, the enumeration ends with ", " instead of ", and ".

• string_magic: the if-else operation & now keeps memory of variables accessed within data sets:

data = list(x = c(15, 25, 550), y = rnorm(1000))
string_magic("The values are{& length(data$x) < 5 ; : {enum ? .} ;  too many}.")
# [1] "The values are: 15, 25 and 550."
string_magic("The values are{& length(data$y) < 5 ; : {enum ? .} ;  too many}.")
# [1] "The values are too many."

• string_magic: new operation deparse (alias: dp) to deparse an object and keep only the first characters of the deparsed string.

• improve error messages.

Aliases

• new battery of short aliases: sma for string_magic, catma for catmagic, mema for message_magic, etc.. (st_ops, st_is, st_any, st_all, stextract, stwhich, stget, stclean, stvec, streplace, stsplit -- short names with vowels after st have an underscore.)

stringmagic 1.0.0

First public release. The syntax should be stable.

This package is a spinoff from fixest's formula syntax interpolation.

Many thanks to Achim Zeileis, Vincent Arel-Bundock and Kyle Butts who provided insightful comments during the development.
