It seems like most of the style insensitivity issues are to do with FFI to case
sensitive languages like C, where library developers have relied on case to
distinguish variables, rather than problems developing in native Nim itself.
In regard to aliasing, I often find myself wanting a shorter name as a direct
reference to something without a copy. A small wrapper for the template
declaration makes things a bit nicer, if you don't need parameters.
template alias(original, newName: untyped): untyped =
template `newName`: auto = `original`
# easier deep referencing
type
MyObj3 = object
data: string
MyObj2 = object
obj3: MyObj3
MyObj1 = object
obj2: MyObj2
var obj1: MyObj1
alias obj1.obj2.obj3.data, data
data = "Test"
assert obj1.obj2.obj3.data == "Test"
# replacing result
import strutils, sequtils
proc starredWords(curStr: string): string =
alias result, words
words = ""
for s in curStr.split(' '):
alias "*" & s.strip.capitalizeAscii & "* ", starredWord
words &= starredWord
var sw = starredWords("hello I like teapots")
echo sw
# only allow alias template in block scope
template alias(original, newName, actions: untyped): untyped =
block:
template `newName`: auto = `original`
actions
var inputStr = "abc"
alias inputStr.toUpperAscii, t:
echo t # t is only defined here
