dialog_file_open_dialog I prefer big.LITTLE cpus

Create a file handler class to avoid the issue

I don't know and that's the problem :(

I keep asking myself what to choose, only for changing it a day after cursing myself to choose a stupid name.

Big endiant is great for intellisense to quickly browse possibilities, since it groups it all in the same place. But that's also a detriment when you know what you want. You can start typing without the prefix but you'll have to go through the better suggestions of intellisense first.

Little endiant is the same thing, but in reverse. Great when needed, but bad for browsing.

Although I do have some fix I'm starting to use. But it's not applicable everywhere, and not in every language.

What I do is use module as prefix. Instead of dialogue_file_open, I create a file_open in the dialogue module, allowing either directly calling file_open, or dialogue::file_open. Using intellisense on the module allow for easy browsing too!

Although in OP's post I'd rather have file_open_dialogue as it convey the more significant meaning, being to open a file, first. Then "dialogue" is just the flavour on top

Romance language word order noun_descriptor is the right way.

in general, adjectives and verbs after nouns because it's more organized/easier to search/filter. as god intended.

I know I'm late to this but here's my (probably insane?) take. We use Subject-Verb-Object in English right? So, hear me out:

dialog_create_tab(...)
dialog_open_file(...)
dialog_close_file(...)

We just call those Smurf names.

As a rule of thumb, I always put action verbs at the end of method names
