Expand any number of arguments with yasnippet

I will show you how to create any number of fields with yasnippet. The source code can be found on github. (Please refer to the link above for how to use yasnippet in the first place)

Expansion of arbitrary arguments

yasnippet can write emacs lisp directly in snippet by writing # type: command in header, which enables automatic generation of snippet. A docstring based on the coding conventions adopted by numpy (based on PEP8, PEP257) in this way. I made a snippet about the argument part.

First of all, please have a demo video. !!

• If it is a def docstring, parse its argument, and if it is a class docstring, parse the argument of def __init __.
• For parse, the function definition part is passed to the python interpreter.
• The maximum number of lines for the function definition is 5. (There is no positive reason for the number 5)

You should be able to make more complicated and convenient snippets by working hard on emacs lisp. We look forward to your hot snippets.

I will also introduce another continuous expansion that combines the above snippet and snippet that creates a function with a docstring.

Continuous development of snippet by hitting tab repeatedly

Also, to achieve this, use .emacs

.emacs

(setq yas-triggers-in-field t)

It is necessary to write.

As before, please watch the demo video first.

• In yasnippet, various behaviors change depending on whether the field is being edited. The operation of the tab key is one of them.
• Normally, you cannot enter the operation during editing by tapping tab repeatedly.
• Here, emacs lisp that can be embedded in snippet is used to convert the original character string to force it to be edited.
• Furthermore, by making the converted character string the same as the key of the snippet you want to expand, you can expand it as it is.
• Since it can be expanded by hitting tab repeatedly, it can be expanded continuously as if the snippet was expanded as usual.

that's all.
