The send_to_all function change is from https://code.launchpad.net/~widelands-dev/widelands/fh1-maps-multiplayer/+merge/337506, so that branch needs to be merged first.

Took the freedom to adjust the RST parts. Mainly:

- make lists of allowed attributes a bulleted list (i think this was intended)
- fixed some args
- fixed indentation to have it consistent over the pages
- added the function definition of new_objectives() in richtext_scenarios.lua
- added some links in the text

For the allowed attributes it would be nice to have a description how to use them. Something like

Attributes have to be applied as a string in form of "attribute1=value1 attribute2=value2": E.g. font("color=ff0000 italic=1", text)

Don't know were to put such an example though.

Hm, we now have the allowed attributes documented in 2 places. The reason that I documented them in the C++ code is to be close to the code, so that we won't forget to update the documentation when they change. We can pretty much guarantee that updating the documentation in richtext.lua will be forgotten eventually.

I didn't add any documenation ;)

Double documentation is not good. What about having the richtext documentation in the cpp file and parse it like we have for src/scripting/lua_bases.cpp? -> https://bazaar.launchpad.net/~widelands-dev/widelands/trunk/view/head:/doc/sphinx/extract_rst.py#L18

The real problem is that we have two different document generators with different syntax: doxygen and sphinx. So making documentation for one of them means it does not work with the other one. I'ts also bad for devolpers, because they have to use two different syntaxes for the source code documentation. Sphinx is also capable to document c++ code, imho: http://www.sphinx-doc.org/en/stable/domains.html#id2 In the long term run there should only be one source code documentation generator, imho.

But you did add some, in this commit: https://bazaar.launchpad.net/~widelands-dev/widelands/fh1-documentation/revision/8429

It would be better to link to the allowed attributes documentation in src/graphic/text/rt_parse.cc and not duplicate the documentation in the Lua file.

I also still need to rewrite the main Richtext document https://wl.widelands.org/docs/wl/wlrichtext/ and link everything together in a tree.

Ok, i correct my self: I did not add any documentation which were in two places:

> Hm, we now have the allowed attributes documented in 2 places.

The allowed attributes were already at 2 places in the documentation, before i edited the RST comments. My fault that i didn't mention this. But please don't make me feel guilty for things i haven't done :-)

I have now rewritten the main article and added a table of contents to it. I have also hooked up the attributes documentation for 2 tags. Before I continue with those, what do you think?

I also think that I should reorganize the richtext.lua script so that we can divide the documentation into logical sections for easier reading.

kaputtnik (franku) wrote :

I think this is good now. For the first time it is confusing that we have functions and the '<>' tags when switching between the pages. It's unclear where one has landet after clicking the link to attributes. Maybe write it in another way?

Instead:
attributes (string) – the attributes for the img tag.

Something like:
attributes (string) – see the rt-tags documentation for the attributes #attributes is the link

Good work :-)

The grouping into headers is nice. A user can find the things he needs much better. There is one exception though: The rt tags documentation contain too much headers, imho. E.g for <rt> there are headers 'Attributes', 'Padding', 'Background Color' and 'Global Formatting Controls'. While the subheaders are a bit smaller it's nevertheless confusing. I think it would be better to have all attributes in one list. The attributes names are quite self explaining, imho. Same goes for the <div> tag. Just like it is for the <p> tag: One header 'Attributes' and a list of all attributes.

I miss an example how to use the attributes.

I am unsure about tags with no attributes or no subtags. I think we could omit the headers if there are no entries in it. A reader can imho understand if there is nothing documented, there are no attributes or subtags possible.

Added also two diff comments.

All done.

For code examples, I just linked back to the main code example. Is this OK for now? Some of the attributes are still a bit WIP.

kaputtnik (franku) wrote :

I think this is better :-)

Maybe i have not explained enough about the code example for the attributes. The reason why i am so stubborn for a related code example is that it took me some time to fiddle out how to use them. E.g. it was unclear how to use values for an attribute.

I would suggest to change the code example in richtext.lua to something like:

-- h1(_[[Header]]) ..
-- p(_[[A Paragraph]]) ..
-- p(_[[A Paragraph with ]] .. font("color=ff0000", _[[red text ]]) .. _[[and ]] .. font("italic=1", _[[italic formatted text.]])) ..
-- and so on

No idea if this code will ever work :-D But hopefully it shows what kind of code example i miss. I could add such an example with a related image, if you don't want to do the additional work to create such an image. May i could test then also if i have understand all the things ;)

I have found some misspelling, will do a complete proof reading this weekend.

Maybe it would indeed be best if you created the examples - I am too close to this, so you know better what is needed here.

Changed the code example and the resulting image. I have tried also to explain in short what the '..' are used for. While a first reader may does not know what my explanation means exactly, one can search the web for the keyword.

Feel free to rephrase :-)

kaputtnik (franku) wrote :

Ah forgotten: Not directly related to this branch but a question about the translation makro '_' and the use of brackets for strings instead of double quotation marks:

Does the _ only work with '_[[some text]]' and not with _"some text"?

The doc for _ (https://wl.widelands.org/docs/wl/autogen_globals/#_) says _"some text" can also be used.

Why are then all strings in the campaign files enclosed with brackets? Is there a benefit of using [[ ]] in comparison with using ""?

GunChleoc (gunchleoc) wrote :

Thanks for the image! I have also changed the code example in the main article to match. The red is a bit glaring, maybe we can have different color, just toned down a bit? I also fixed a spelling error in the text contained in the image, so it needs rerendering anyway.

It doesn't matter whether we use "" or [[]] in Lua. [[]] is for multiline strings that will ignore newlines, but using those would make for weird strings presented to translators. https://www.lua.org/manual/5.3/manual.html#3.1

kaputtnik (franku) wrote :

Thanks for explanation.

I have used now blue and white instead of red and completed the example. In r8443 i have changed both code examples accordingly. In r8444 i have removed the code example from wlrichtext and linked the example in richtext.lua. Feel free to revert this change, but one example is better for maintenance, imho.

Did now some proof reading, see inline comments.

What i stumbled over is a mixed use of uppercase/lowercase after hyphen/colon. Eg. for the two text composition functions we have:

In join_sentence() its lowercase:
:arg sentence1: text of the first sentence

In localize lists its uppercase:
:arg items: An array of strings

I'm not font of the blue either, can you please try something like 6699ff? The problem wasn't the hue, but the saturation.

893 The Widelands Rich Text System
894 ==============================
895
896-All texts that can be displayed to the user can be formatted to be layouted
897+All texts that can be displayed to the user can be marked up to be laid out
898 and nicely formatted. This allows for changing of font sizes, weights, colors
899 and for the embedding of images. This documents how to format a string to be
900 recognized as rich text and which attributes are understood.
901
902 The Widelands rich text language is inspired by HTML and therefore uses a
903-syntax very similar to it. A rich text is started with ``<rt>`` and ended with
904-``</rt>``. A rich text can have an image associated with it, this image is
905-then displayed next to the text.
906-
907-Inside the rich text, each paragraph is enclosed by ``<p>`` and ``</p>``. You
908-give font attributes to this tag to change the appearance of the text
909-displayed inside.
910-
911-Reference
912----------
913-
914-``<rt>``
915-^^^^^^^^
916-
917-Starts or ends a rich text. Must be the first tag to appear in the string.
918-A full example would be::
919-
920- <rt image=map:khanktrukh.png><p line-spacing=3 font-size=12>Hello<br>World</p></rt>
921-
922-This would instruct widelands to use the image of Khankruth that comes with
923-the map, left align it. To the right of it there would be two lines of text.
924-The first line being ``Hello`` and the second being ``World``. They would be
925-displayed with a font-size of 12 points and a line-spacing of 3 points.
926-
927-Valid attributes for ``<rt>`` are:
928-
929-image
930- The name of a image to use, can be prefixed with ``map:`` which instructs
931- widelands to load the image from the ``pics/`` directory inside the map of
932- this scenario.
933-
934-image-align
935- ``right``, ``center`` or ``left``. Defines were the image is displayed.
936-
937-text-align
938- ``right``, ``center`` or ``left``. Defines were the text is displayed.
939-
940-
941-``<p>``
942-^^^^^^^^
943-
944-A text paragraph inside a rich text. This gives control over which font is
945-used for rendering and how it should be formatted.
946-
947-Valid attributes for ``<p>`` are:
948-
949-font-size
950- The font size to use in points. 10 points is the default. Use 12 points for
951- mission texts.
952-
953-font-face
954- Font face style of the font to use. The valid fonts are ``sans``, ``serif``,
955- and ``condensed``.
956-
957-font-color
958- The color of this font as a RGB hex tuple. That means 000000 is completely
959- black while ff0000 is completely red. Default color is a bright yellow
960- (ffff00).
961-
962-font-weight
963- ``normal`` or ``bold``. Note that not everything is supported by all fonts.
964- Do not use with ``font-style=italic`` at the same time; double formatting is
965- typographically bad.
966-
967-font-style
968- ``normal`` or ``italic``. Note that not everything is supported by all fonts.
969- Do not use with ``font-weight=bold`` at the same time; double formatting is
970- typographically bad.
971-
972-font-decoration
973- ``normal`` or ``underline``. Note that not everything is supported by all fonts.
974- Do not use with ``font-weight=bold`` or ``font-style=italic`` at the same time;
975- double formatting is typographically bad.
976-
977-line-spacing
978- Line spacing in points. Default is 0.
979-
980-``<br>``
981-^^^^^^^^
982-
983-This inserts a line break into the text. The line break character (``\n``) is
984-ignored inside a rich text.

986-Real world Lua example
987-----------------------
988-
989-Here is a small example of a fancy message send to the user via the
990-:meth:`wl.game.Player.send_message` method:
991+syntax very similar to it. To tell our rendering system to go into richtext mode,
992+start your text with ``<rt>`` and end it with ``</rt>``.

1001+
1002+Code Example
1003+------------
1004+
1005+Here is a simplified version of a fancy message displayed to the user:
1006
1007 .. code-block:: lua
1008
1009- wl.Game().players[1]:send_message(
1010- "Hi",
1011- "<rt image=images/logos/wl-ico-128.png image-align=center></rt>" ..
1012- "<rt text-align=center>" ..
1013- "<p font-weight=bold font-decoration=underline font-style=italic font-size=24>" ..
1014- "YOU so rock dude!" ..
1015- "</p></rt>" ..
1016- "<rt><p>No. I really mean this.<br><br>Seriously.</p></rt>",
1017- { popup = true }
1018- )
1019-
1020-The title of the message mustn't be a rich text, the body (which is just one
1021-string, it has been separated for easier reading and concatenated Lua-style
1022-via the ``..`` operator) is one: the first rich text includes a centered image
1023-and no text. The second is the text ``YOU so rock dude!`` in italic, bold and
1024-underlined. Then a simple text follows in four lines -- two of them being
1025-empty. The message popups the message window when it is received.
1026-
1027-The complete message rendered looks like this on my system:
1028-
1029-.. image:: images/fancymsg.png
1030- :scale: 100
1031- :alt: sample rendering
1032- :align: center
1033-
1034-
1035+ body =
1036+ "<rt> -- This is richtext
1037+ <p> -- Start a paragraph
1038+ <font size=18 bold=1 color=D1D1D1> -- Set font size and color
1039+ Big font to create a header
1040+ </font>
1041+ </p>
1042+ <p>
1043+ <font size=12>
1044+ Normal paragraph, just with a bit more text to show how it looks like.
1045+ </font>
1046+ </p>
1047+ -- The following content should be spread across a full line
1048+ <div width=100%>
1049+ <div>
1050+ <p>
1051+ <font size=12>
1052+ <img src=images/wui/menus/menu_toggle_menu.png>
1053+ </font>
1054+ </p>
1055+ </div>
1056+ <div width=*> -- Fill up the remaining space
1057+ <p>
1058+ <font size=12>
1059+ Another normal paragraph
1060+ </font>
1061+ </p>
1062+ </div>
1063+ </div>
1064+ ...
1065+ </rt>"
1066+
1067+This is quite a lot of hacking, so we have :ref:`Lua convenience functions <richtext.lua>`
1068+set up. We recommend that you always use those while scripting in Lua, which will
1069+also give us consistency in style throughout Widelands.
1070+Using the convenience functions will also result in cleaner code when
1071+including translation markup (the ``_[[Some text]]`` or ``_"Some text"`` function).
1072+
1073+A code example how to use the convenience functions and their attributes is given in the
1074+documentation for the :ref:`richtext convenience functions <lua_formatting_example>`.
