Some thought about user experience of the ide plugin rescript-vscode

[Mng12345]

After using rescript for months, i am deeply impressed by rescript which is an awesome language, it is better than typescript i think. But the user experience of it’s ide is terrible:

1. The format on save problem about %raw block which will cause much blank lines in %raw block
2. The tips is just poped after you saved you file, while it can be poped when you code typescript whether or not to save file
   The user experience of changing from typescript to rescript in vscode is like coding java from using IDEA to notepad

Concerning your second point, you can activate autosave as a workaround:

Easy workaround in rescript-vscode for instant error reporting

As it bothered me that rescript-vscode requires a manual save to update error reporting, I found out a little workaround. Just use autosave by adding this to your settings.json: "files.autoSave": "afterDelay", "files.autoSaveDelay": 200, It seems that autosave does not include formatting, so you do not need to disable formatOnSave. NOTE: I only tested it in smaller files. If it affects performance too much, you could tweak the delay a bit.

The formatting is not functional in autosave mode. It’s the type system makes me rewritting my old project from ts to rescript, but the editor plugin is not good enough yet

I find the auto formatting stops working after awhile, but if I restart VSCode it then works again.

You might like “Restart Extension Host” in the Command Palette, which avoids having to quit the IDE.
