lines beginning with | after a fun no longer indent

[peteraldous]

All of the SML tools I've used format code differently from what I expect; lines beginning with | are indented, but the convention I'm used to is that if it's an alternate pattern for the fun, the | should match and not be indented further:

fun fact 0 = 1
|   fact n = n * fact (n-1);

I modified the indentation logic to change this behavior. I'm new to vimscript and plugins; I will happily accept edits or implement suggestions.

Hey, thanks for the suggestion.

I like the way it indents right now, and I have to assume that the majority of people using this plugin also use it because they like the current indentation behavior.

I checked some SML formatters:

• smlfmt
• autoformat
• smlformat

And they all format fun patterns the way that this indentation plugin formats them.

I'm open to building this behind a configuration option, so long as the default (unconfigured behavior) is the same as the current behavior.

I believe a good name would be g:sml_indent_fun_pipe_position, accepting two string values: "begin" and "indented". You can read :help get() for information on how to get the user's configured value or else fall back to a default value.

If you go with this approach, please be sure to update the :help vim-better-sml-config section to document what this option does.
