Nim Cookbook with examples

mixed bag seq: allow strings and int in a seq

how to get a 'mixed bag seq' in Nim. I probably need to learn about generics... In Crystal: mixed_bag_seq = [1, "aa"] Run here is Nim example that fails: proc foo(a: int|string): int|string = # works: both string and int accepted discard

strscans - Error: undeclared identifier: 'scanf'

bummer yes, it works fine in terminal. So the issue is related Visual Studio Code

one line of code "import strscans" results with error. What am I missing? Is it a bug? import strscans # error # Hint: used config file '/Volumes/T5/.choosenim/toolchains/nim-1.4.8/config/config.nims' [Conf] # Hint: used config file '/Volumes/T7/Nim/_my_code_ex/conf

This is the closest to the Nim Cookbook. * yes, we need a a cookbook...

Any improvements, shorter, more idiomatic (golf?) Nim? import times, algorithm var today = now() var sq: seq[string] for i in 1..3: var duration = initDuration(days = i) var next_day = today + duration sq.add($next_day.format(", dd-MMM-"))

Why Nim is *not* confused - which proc to call?

I am a beginner and learning about "Generic procs". How Nim finds the correct proc 'min' to call? I was expecting error message: ambiguous proc name 'min' \- add module to make it clear which 'min' proc do you mean... Yet - it works just fine. proc min[T](x, y: T): T = if x <

wikipedia: nim reference - regex engines - comparison

yes, so what should be a correct comment on Wikipedia ?

regex

whoops - "re" and "regex" are different :-) ... read the manual ... : import regex match "uabyxabyzc", rex"ab.z": echo matches Run

regex

works fine: import re echo find("uabyxabyzc", re"ab.z") # found pattern "ab.z" at position 5 Run when I flip from re to regex: import regex # <== change "re" to "regex" echo find("uabyxabyzc", re"ab.z") # found pattern "ab.z" at position 5

How I should update wiki page: * Currently the comment is: * Standard library includes PCRE-based re and nre modules, as well as various alternatives (ex. strutils, pegs (Parsing Expression Grammar matching), strsca

learn Nim regular expressions - regex, re , NRE

@didlybom1h , what languages add regex to the core / stdlib? But I guess even if there are languages do this - the next question is - would it be the right thing to do? I was learning Ruby and Python before - they both must import regex... There is probably a good reason for this behavior.

echo isAlphaAscii("ą") - expecting false (instead of error)

Python is weakly typed - so it is not a fair comparison - but it is much more forgiving: mystr = "ą" print(mystr.isascii()) # response: false Run What is the risk of taking _both_ types: the string AND the char type and gracefully respond with false if the strin

python: print(x, end=" ")

Python allows large number of variables to be printed on the same line (without line return) Please compare: var x = "aa" var y = "bb" stdout.write(x, " ", y, "\n") Run # stdout.write(x y z & " ") # error # stdout.write(x, y, z & " ") # error x = "aa
