WIP: Vala #2320

albfan · 2019-11-13T08:00:07Z

Work in progress for vala parser.

Written from scratch.

Right now is just a plain copy/paste from tcl parser

relates to #621

coveralls · 2019-11-13T08:59:01Z

Coverage increased (+0.04%) to 86.407% when pulling 7692199 on albfan:vala into 2ebf5b1 on universal-ctags:master.

albfan · 2019-11-16T14:06:27Z

I think this is a wrong way to approach the implementation.

albfan · 2019-11-16T18:34:43Z

Reopening this as is the only acceptable approach to include vala into ctags.

@masatake I have first question on this parsers:

How to detect a vala field (inside a class) and a property (field with get and set:

class Address {
   public string street; 
   ...
}

class Person {
   public Address address;
   public string name {get; set;}
   ...
}

Understanding this seems the key to me. (maybe I should reread the links you suggest right now?)

How to detect a vala field (inside a class) and a property (field with get and set:

Please show the pair of "input.vala" and "exepected.tags". The pair is very important for me to understand what you need. If you cannot image "expected.tags" for the input, I cannot help you. In that case, what you have to do is reading ctags(1) man page carefully.

Units/parser-vala.r/class.vala.b/expected.tags

albfan · 2019-12-02T17:14:10Z

I added a review comment in expected.ctags that will be my approach to reimplement this, and once I see how to understand the scope for a tag (things inside a pair) things that depends on several previous tokens I will figure out myself the rest.

Thanks for help here!

masatake · 2019-12-02T17:49:31Z

I promised @k-takata I will focus on releasing related work till we can find a long term volunteer who drives the documentation related work of this project.

So I will show only sample code. I hope it helps you.
Ideally, I should consider the work of your side.

masatake · 2019-12-02T19:18:54Z

See #621. I updated my branch.

albfan · 2019-12-02T23:05:37Z

@masatake I think I get it. I rebase this on top of your branch (I rebased on top of master too.

parseClassBody is really helpful. Let's see if I can complete the rest on my own.
