syntax-begin-function obsolete in Emacs 25.1

[Parent5446]

As of Emacs 25.1 the syntax-begin-function variable is obsolete. I am not sure what the replacement is.

Here is the compiler warning received:

typescript-mode.el:2052:10:Warning:
    `syntax-begin-function' is an obsolete variable (as of 25.1).

I'd hate to use anything PHP as a reference for this, but it seems php-mode has encountered the same issue and had a ... fairly pragmatical approach to it: emacs-php/php-mode#340

I guess we could do the same, since we too have to support older version of Emacs.

That said, what I find most annoying about this is that I cannot anywhere find any documentation on what this is deprecated in favour of. Basically. What should we replace it with? Anyone have any idea?

If there's a reasonable (and backwards compatible) thing we can do instead, I'm all for it.

If not, I say we ignore the warning until it causes actual errors.

Note: This is incidentally fixed in PR #45.

The warning about syntax-begin-function came up recently in #102 There's nothing to be done from the perspective of maintaining functionality. syntax-begin-function is just no longer used, with no replacement. Setting it in newer Emacs causes a warning but is not otherwise harmful. I'm closing this in favor of #102 where we've been focusing on how to suppress the warning, which is the only issue that remains really.

(Historical note: it turns out that PR #45 was never merged and so has no bearing on how we're using syntax-begin-function.)
