|
|
You can use the slanted quote string syntax if you need to use a reserved word as an identifier: ``var `type`: int``

## Tricks with conditional compilation
|
|
|
|
```nimrod
|
|
when defined(useSomeFeature):
|
|
const someSubFeature = true
|
|
type ID_Type = int32
|
|
var defaultUserName = "Frank"
|
|
else:
|
|
type ID_Type = int16
|
|
var defaultUserName = "Molly"
|
|
|
|
# `when` does not open a new scope, so `ID_Type` and `defaultUserName`
|
|
# are available here.
|
|
|
|
when isMainModule:
|
|
#this code is ran only when this module is the main compilation module
|
|
echo "This module was compiled on ", CompileDate, " at ", CompileTime
|
|
```
|

|
|
#### Defining `useSomeFeature`
|
|
* Do it when you compile: `$ nim c -d:useSomeFeature myApp`
|
|
* Put it in the local `nim.cfg` file `define:useSomeFeature`
