Locale
Harlequin uses your system’s locale (the language, region, and other country-specific settings) to format numbers (for example, to set the thousands separator). If the system’s locale is not set properly, Harlequin’s numbers may look strange to you.
The Special “C” Locale
Some computers have their locale set to C (or C.UTF-8), which is the POSIX standard for “Computer” — it is optimized for servers or other environments that should not localize values. Using Harlequin with the C locale shows numbers unformatted, wihout a thousands separator. This probably isn’t what you want.
If Harlequin finds itself running in the C locale, it attempts to set the locale to en_US.UTF-8 and prints a warning that is viewable on exiting Harlequin.
If you do want to use Harlequin with the C locale, you can either uninstall the en_US.UTF-8 locale from your OS, or just run Harlequin with the --locale C option.
Setting The System Locale
- Mac: See Mac Help. tldr: Apple > System Settings > General > Language & Region; set Number Format.
- Ubuntu: See Ubuntu Help. tldr:
sudo nano /etc/default/locale - Windows: See this blog. Update the Language and/or Region.
Overriding the System Locale
You can also just pass a --locale option to Harlequin, like this:
$ harlequin --locale en_US.UTF-8If the passed locale is not installed on your system, Harlequin will exit with an error.
As with other options, this value can be saved to a profile in a config file. You can create a profile with harlequin --config. See the help on config for more information.
