Either the current line count is wrong, or you added the wrong number of
new lines to PageOutput(). Your patch only adds four \n, while you
increased from 81 to 87.

I though about it, and we cannot to drop it now. These symbols are

I am thinking so 05 patch should be final

yes, it is better. I didn't understand before.

I though about it because it allows to design multiline end style in future.

I am not a fan of "↵" and "…" in resulted tables, and can be nice if I can
to optionally change it.

With your change we can design other "pure" style against current "rich"
style. But I don't have a idea, how to name it.

All I was suggesting was pulling these strings out of the function:

+   /* ↵ */
+   popt->header_nl_right = "\342\206\265";
+
+   popt->nl_left = " ";
+
+   /* ↵ */
+   popt->nl_right = "\342\206\265";
+
+   /* … */
+   popt->wrap_left = "\342\200\246";
+   popt->wrap_right = "\342\200\246";

and adding them to unicode_style and then referencing them there,
similar to how the rest of printTextFormat popt (by the way- don't
really like that variable name, particularly as it's used elsewhere with
a very different meaning..  why not 'format' or 'ptf'?) is
set up in refresh_utf8format, that's all.

Thanks,

Stephen

I am not sure if I understand well.

With refresh_utf8format I can do shortly 6 possible combinations - or more
(when it will be requested)

I have no idea how to write as rest without repeating all 6 combinations -
what was one noticed issue of some older variant, where I designed
unicode1, unicode2, ...

Any idea, tip how to it?

Pavel

This is certainly better, imv, though there are a couple of minor
issues (extra semi-colons, extraneous whitespace, get_line_style was
still changed to non-const, even though it doesn't need to be now).

I don't particularly like this (having these fields set in
refresh_utf8format to hard-coded strings in the function), why not have
those handled the same as the rest, where the strings themselves are in
the unicode_style structure?

The rest looks pretty good.  Need to step out for a bit but I'll look at
making the above changes when I get back if I don't hear anything.

Thanks,

Stephen

Hi

I removed dynamic allocation  and reduced patch size.

What I tested a old unicode style is same as new unicode style. There
nothing was changed .. some fields are specified in refresh_utf8format
function

I've started looking over the patch and went back through the previous
thread about it.  For my part, I'm in favor of adding this capability,
but I'm not terribly happy about how it was done.  In particular,
get_line_style() seems pretty badly hacked around, and I don't really
like having the prepare_unicode_format call underneath it allocating
memory and then passing back up the need to free that memory via a new
field in the structure.  Also, on a quick glance, are you sure that the
new 'unicode' output matches the same as the old 'unicode' did (with
pg_utf8format)?

I would think we'd simply set up a structure which is updated when the
linestyle is changed, which is surely going to be much less frequently
than the request for which linestyle to use happens, and handle all of
the line styles in more-or-less the same way rather than doing something
completely different for unicode than for the others.

Thanks,

Stephen

I did a quick review of the patch today:

* it applies cleanly to current HEAD (no failures, small offsets)
* compiles and generally seems to work just fine

Two questions:

(1) Shouldn't the new options be listed in '\?' (as possible names for
"pset")? I mean, here:

  \pset [NAME [VALUE]] set table output option
 (NAME :=
{format|border|expanded|fieldsep|fieldsep_zero|footer|null|
numericlocale|recordsep|recordsep_zero|tuples_only|title|tableattr|pager})


(2) I noticed this piece of code:

+typedef enum unicode_linestyle
+{
+   UNICODE_LINESTYLE_SINGLE = 0, /* to make sure someone initializes this 
*/
+   UNICODE_LINESTYLE_DOUBLE = 1
+} unicode_linestyle;

Why are the values defined explicitly? These values are set by the
compiled automatically, so why set them manually? Only a few of the
other enums are defined explicitly, and most of them have to do that to
define different values (e.g. 0x01, 0x02, 0x04, ...).

I don't understand how the comment "to make sure someone initializes
this" explains the purpose?

> So possible line elements are:

> * border,
> * header_separator,
> * row_separator,
> * column_separator,
>
> Possible styles (for each element)
>
> * none,
>  * single,
> * double,
> * thick,
>
> It should to have enough variability to define all styles proposed early.
> I hope, so this proposal is secure and simple for usage. Styles should be
> persistently saved in .psqlrc file - and some examples can be in
> documentation.

> Usage:
>
> \pset linestyle_border double
> \pset linestyle_header_separator single
> \pset linestyle_row_separator single
> \pset linestyle_column_separator single
>
> \pset linestyle unicode
