…rmation and syntax autocompletion (#603) ## Changes * In the Mathematica options inspector, there is an option called `"HighlightMissingArgumentsWithTemplate"`. * If you turn it on, in case of missing arguments, instead of displaying a single red arrow, you will get a helpful hint with argument names which can serve as a super fast lightweight documentation (like you would get in, e.g., Xcode after autocompleting a function): <img width="362.4" alt="HighlightMissingArgumentsWithTemplate" src="https://user-images.githubusercontent.com/1479325/106001860-133b6880-6076-11eb-8fd8-a8549dfe4ac6.png"> * The names of the arguments are taken from pattern names in `SyntaxInformation`. * This PR adds names to all `SyntaxInformation` except for the built-in `RulePlot` thus enabling this feature for all *SetReplace* symbols. * This also adds missing usage messages, syntax information, and syntax autocompletion. * Expands argument names in usage messages to be descriptive so that using autocompleted templates are more informative. ## Comments * `Null` is due to `OptionsPattern[]`. It can be changed to, say, `opts` if that pattern is named as `opts : OptionsPattern[]`. However, if one does that, some optional arguments will always be displayed in the template, which is, of course, unacceptable. I think we'll have to wait until this weed is fixed upstream: <img width="324.0" alt="image" src="https://user-images.githubusercontent.com/1479325/106002768-200c8c00-6077-11eb-9d79-3a4e07caa2bc.png"> * Autocompletion is generally disabled for option names. The problem is that I'm not aware of a way to enable autocompletion for multiple arguments at a time. In order to solve this, we need to use symbols instead of strings for options (#604), and we need to figure out how to autocomplete the values for enum-like options (#605).

The problem
We have some options the values of which contain strings that should support autocompletion. For example,
"EventOrderingFunction".Possible solution
Some built-in options, e.g.,
GraphLayoutcan do that already. We just need to find out how they are implemented. It might be necessity to switch options to use symbols instead of strings first (#604).The text was updated successfully, but these errors were encountered:
