.data to string_magic(), used to evaluate variables in the interpolationsst_ops, st_is, st_any, st_all have been renamed into stops, stis, stany, stall to align with how all other aliased have been created. Although the names aren’t great, at least they are consistent.the new operator swidth (screen width) replaces the operator width. The operator width becomes an alias for fill.
the default screen width for message_magic becomes the minimum between 100 characters and 90% of the current screen size (actually the console size).
improve error handling
add left option to operators when relevant. Thanks to @kylebutts, #3
stringmagic compatible with R < 4.1.0 by removing calls to ...names().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.
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.
