Semicolon at the End of Line option about fantomas HOT 11 CLOSED

The rationale behind this is:

• You can merge two lines of record files into one without inserting ;
• It's safer. The code can still be parsed if indentation is slightly off or there are some comments being inserted.
• I did this due to my subjective view

@dsyme What do you think about this?

from fantomas.

In C# I always leave trailing commas in enums and object initializers because of the first reason you gave, but in F# for some reason I don't like trailing semi colons. I usually split list expressions into multiple lines (unless it's a very small list) just to not have to put them. Maybe it's just a semicolon trauma :)

from fantomas.

I'm convinced. Will update accordingly.

I sent @dungpa an email about the formatting defaults. I recommended
* 4 space indent by default, and make this an adjustable option
* Space Before Colon false
* Semicolon at End of Line false

It would also be nice if fantomas could detect the number of space indents being used in each file, similar to what sublime test does. I usually use 4 spaces, but Tomas likes to use 2 in FSharp.Data, so I'll probably be doing a lot of switching

About indent size, it is adjustable but in another dialog http://msdn.microsoft.com/en-us/library/ms165330(v=vs.80).aspx

It's the way Ivan implemented in the initial version. I think it is reasonable and consistent with VS editors.

Oh I see. Hmmm... I personally use "2 space" for the TAB [ actually I mean Indent ] setting in Visual Studio, but actually indent F# code by 4 spaces. This means I use TAB twice to indent the 4 spaces. But that's not what most people will be doing, so what you have makes sense.

I'll try switching to 4 space TAB [ actually I mean Indent ] settings when using Fantomas.

from fantomas.

No. You just need to change "Indent size" option to 4 and keep Tab size to be 2. I don't know how Indent size and Tab size interplay in VS editors.

from fantomas.

Right, where I said "TAB" I meant to say "Indent". The TAB size setting in Visual Studio is essentially irrelevant for F# code.

from fantomas.

In MonoDevelop Im in the middle I always use three spaces :)

Steps to fix if anyone would like to handle this issue:

• Change default value of SemicolonAtEndOfLine to false in https://github.com/dungpa/fantomas/blob/master/src/Fantomas/FormatConfig.fs#L28.
• Fix failing unit tests
