Feature Request: Include parentheses when tab completing functions

[mskar]

Tab completion in RStudio shows functions without parentheses in the completion menu: but when I tab complete a function the parentheses are included and my cursor is inside the parentheses: I would like tab completion of functions in radian to behave the same way (i.e. add parentheses after the function name and put my cursor inside the parentheses): The desired result in radian would look like this: Adding parentheses to completed functions is the default behavior in

• VSCode (R pluginby Yuki Ueda):
• the R language server. Could the code from the R languageserver issue above be adapted to radian? I think this feature would be widely appreciated by users and should be the default behavior for tab completion of functions. Some users may prefer the current behavior, so ideally it would be controlled via a setting in .radian_profile.

I submitted a pull request that implements the changes described above: #229.

Note: This also completely changes how completion works:

Tab:

• does not cycle thru completion options and instead
• accepts completion if there is only one completion option
• starts completion if there are multiple options and the completion menu is not showing
• accepts the selected completion option if an option is selected
• accepts the first completion option if the completion menu is showing and no option is selected

Enter:

• accepts the selected completion option if an option is selected
• accepts the first completion option if the completion menu is showing and no option is selected
