Hi, all! I'm trying to get the first item out of an OrderedTable that was
indexed with strings. I'm not sure which is the best way to do it.
My program is reading a set of configuration files and loading the information
into a type `Target`, which is then added to an ordered table using the name of
the target as its index. If the user executes a command that takes a target, I
want to get the target using the supplied name as the index (just normalized).
So far, so good. However, if the user does not specify a target, I want to
select the first one that was added to the table.
Here's my types:
type
Config* = object
# ...
targets*: OrderedTable[string, Target]
Target = object
name*, file*, description*: string
sources*: seq[string]
Run
This is the only way I can think of to get the first index:
if opts.target.len == 0:
for target in cfg.targets.keys:
opts.target = target
break
Run
Is there a better way of getting the first index? Or maybe a better way to
structure my data that avoids this?
Thanks!
