Hi all,
It is recommended in ?'if' that we use 'else' right after '}' instead
of starting a new line, but I noticed deparse() will separate '}' and
'else' when the 'if...else' clause is used inside {...} (e.g. function
body). Here is an example:
## if/else inside {}
> cat(deparse(parse(text='function(){if (TRUE) {1} else {2}}')), sep='\n')
structure(expression(function() {
if (TRUE) {
1
}
else {
2
}
}), srcfile = <environment>)
## no {}
> cat(deparse(parse(text='if (TRUE) {1} else {2}')), sep='\n')
structure(expression(if (TRUE) {
1
} else {
2
}), srcfile = <environment>)
I wonder if there is a way to let 'else' stay with '}' when deparsing
the expression. Thanks!
