Output errors so emacs can parse the line number

[audetto]

Currently errors are written to console like this

hello.c(5): Error: Unexpected newline
hello.c(6): Error: ')' expected

which emacs does not parse.

Most compilers output it as

hello.c:6: Error: ')' expected
hello.c:6: Error: ';' expected

which can be clicked on emacs easily.
Change is trivial and I am happy to propose a PR, but I wonder if this has already been discussed in the past.

Apart from the line number notation... Are you specifically talking about Unexpected newline or is this an example for a certain class of error messages? Or are you after all "only" talking about the line number notation?

[audetto]

yes, just the file:line notation that emacs accepts by default.
I am sure one can configure emacs to parse file(line) but patching error.c seems much simpler and portable solution.

cc65/src/cc65/error.c

Line 130 in 5d84a4b

fprintf (stderr, "%s(%u): Fatal: ", FileName, LineNum);

I see other tools with the same syntax (ca65), but I have only used cc65 so far.

[oliverschmidt]

As far as I understand you'd like to see cc65 conform (more) to https://www.gnu.org/prep/standards/html_node/Errors.html

I'm personally open for a change - but it needs to include all parts of the cc65 tool chain.

[audetto]

yes, I agree on both points.

[oliverschmidt]

I suggest that we wait a bit if there are strong opposite opinions. If there aren't, I'm willing to merge a PR consistently changing the syntax.

This has been bothering me recently as well, my editor of choice also likes file:line better - so +1 for changing it :)

[spiro-trikaliotis]

vim recognizes both formats (just tested), so I have no objections. :)

Thank you guys.
This is done now,
