Edit. Project Properties, Build, Switches, Ada At the bottom of the page, there's a summary box, showing all the switches curently selected: you can type -gnatW8 directly in this box, even though there's no GUI for selecting it. By the way, if you're on Windows or macOS, don't use non-Latin characters in unit names! https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81114 ^ permalink raw reply [flat|nested] 18+ messages in thread

With some limitations. For example, π and φ or even φπ are accepted as variable names, but not something like ₢ for example. I guess only Latin 1 characters are allowed. I'm on Linux and have custom .XCompose key combinations to type such things easily, but they don't work in GPS. Curiously, combinations defined in the default XCompose file *do* work, like degree sign °. Don't know if this is some GTK/KDE thing again, but as you see they work fine in Firefox which is also GTK. Thanks for sorting it out for me :-) Cheers, Ian ^ permalink raw reply [flat|nested] 18+ messages in thread

The definition of "Letter" for identifiers is as follows (General Category is from ISO 10646/2017), see 2.1 and 2.3: letter_uppercase Any character whose General Category is defined to be “Letter, Uppercase”. letter_lowercase Any character whose General Category is defined to be “Letter, Lowercase”. letter_titlecase Any character whose General Category is defined to be “Letter, Titlecase”. letter_modifier Any character whose General Category is defined to be “Letter, Modifier”. letter_other Any character whose General Category is defined to be “Letter, Other”. number_letter Any character whose General Category is defined to be “Number, Letter”. For more details, refer to ISO 10646, but be careful: ISO 10646 is 2.5 times the size of the Ada standard! -- J-P.

Do you have to do all 3? Personally I wouldn't bother with (2) because (a) it's the default; unless (b) you're using GNAT CE, in which case it's the only possibility! ^ permalink raw reply [flat|nested] 18+ messages in thread

But if you're not using Pragma Restrictions( NO_IMPLEMENTATION_DEFINED_PRAGMAS ); it's nice to have in the program-text what the character-set is. ^ permalink raw reply [flat|nested] 18+ messages in thread
