Strings - BSVino/JaiPrimer GitHub Wiki
Strings in Jai are a simple standard array collection of Unicode UTF8 characters.
Strings are not null-terminated like in the C language.
To use Jai strings with external libraries that need null-terminated strings some workarounds are necessary.
Escape codes
To insert into the strings special characters, or foreign characters not supported by the editor in use (eg. for internationalization), or to create effects on the console are available several special escape codes.
| Esc | Description |
|---|---|
| \0 | NUL ASCII character for null-terminated strings |
| \n | Newline character |
| \t | Tab character |
| \r | Carriage return character |
| \" | Double quotes character |
| \\ | Backslash character |
| \e[...m | Escape sequence |
| \xnn | Character code addressed by a hexadecimal value |
| \dnnn | Character code addressed by a decimal value |
| \unnnn | Character code addressed by Unicode 16 bit hexadecimal value |
| \Unnnnnnnn | Character code addressed by Unicode 32 bit hexadecimal value |
Escape sequences are used to produce formatted output effects on the terminal console.
A simple effect on the console's output can be achieved in this way:
ESC_RED :: "\e[31m";
ESC_STD :: "\e[0m";
print ("This value is %IMPORTANT !%, ESC_RED, ESC_STD);
But be warned that many terminal emulators and console programs don't support escape sequences very well and some are better than others specially for true colors.
