Incorrect input position in continuous `(p ...)`

[bohonghuang]

Given the following template:

(f (p "public ") (p "void ") (p "function") "(" p ") {" n> q n "}" >)

The cursor will jump to an incorrect position when attempting to overwrite the prompt:

You can either add space between the fields " " or make the fields a single field "public void".

Hi, I found this problem as well. I am not sure if this an issue of the package or the Tempo library. Sometimes, I just need to use two consecutive (p ...) sections.

For example, I am writing a template for a C++ class. It is like

(class "class " (p "ClassName" cname) (p " : public BaseClassName") n>
          "{};" n>)

If I have to merge the two sections into one, then I cannot reference them individually. However, they are two different concepts in the language, and it is natural to represent them using different sections.

If I add space between the two sections, then when there is no base class to inherit, there would be an extra white space.

Although I could live with the solution of using one single section, I do think this issue should be fixed if possible. However, if it is an issue of the Tempo library, I suppose you can't help with it. Still, I prefer to know the real reason of the problem.

By the way, do you know how could I input empty string for a (p ...) section? Currently, I only come out the solution of inputting one character then deleting it, but this feels awkward. In yasnippet, I could simply tap backspace to clear an input field. In tempel, this only deletes the previous character.

@drcxd I don't know how to fix this. The problem is that the modification hooks should catch a field update if the point is directly before or after a field. This makes it hard to support fields which lie directly next to each other. But if you have a fix in the form of a patch, I would be happy to accept it.
