datetime="2024-02-22T04:24:37+00:00">February 22nd, 2024, 4:24 am</time> </p> <div class="content">I'm looking for samples of WML where the preprocessor or parser does something a bit unusual that you might not expect, or where you need to do something a little unusual to make it work correctly. Does anyone have any examples of such things?<br> <br> I'll start with one that I recently noticed:<br> <div class="codebox"><p>Code: <a href="#" onclick="selectCode(this); return false;">Select all</a></p><pre><code>[my_tag] value = _ hello [/my_tag] </code></pre></div> When read in-game, it seems that <code class="inline-code">$my_tag.value</code> has the value <code class="inline-code">"_hello"</code> – the space has been removed.<br> <br> And here's a preprocessor one that I think bites people a lot:<br> <div class="codebox"><p>Code: <a href="#" onclick="selectCode(this); return false;">Select all</a></p><pre><code>#define MY_FORMULA "(if(a = b, 12, 22 ))"#enddef formula = "(base_value + {MY_FORMULA})" </code></pre></div> This ends up being an error. If I understand correctly, the issue is that, due to a macro whose value is quoted being included within a quoted string, the opening quote in the macro wants to be a closing quote. However, it seems a closing quote is not allowed to be followed by characters other than <code class="inline-code">+</code> or whitespace, so you get an error.<br> <br> <span style="font-size:85%;line-height:116%"><em class="text-italics"><strong class="text-strong">Rationale</strong>: The preprocessor and parser are currently messy and hard to extend due to the need to avoid breaking functionality and the lack of unit tests. It's relatively easy to write unit tests for simple, common scenarios, but quite another matter to write them for edge cases. If we can get a lot of weird examples, it would be a big step towards the goal of having sufficient unit tests to be able to be at peace with adding new features.</em></span></div> <div id="sig686672"

Any character that appears after the <code class="inline-code">=</code>, with a few exceptions, is considered to be part of the value of the attribute. It doesn't matter how convoluted it looks or how many punctuation characters appear in it – as long as none of the <em class="text-italics">special characters</em> appear, it's just a string read according to HTML conventions (that is, runs of whitespace are collapsed down to a single space).<br> <br> Thinking about it more, the amended example in my post would probably only work if it was collapsed down to a single line, as a newline <em class="text-italics">not inside quotes</em> always terminates the attribute value. So <em class="text-italics">this</em> should work:<br> <div class="codebox"><p>Code: <a href="#" onclick="selectCode(this); return false;">Select all</a></p><pre><code>#define MY_FORMULA " (if(a = b, 12, 22)) "#enddef </code></pre></div> The special characters that <em class="text-italics">aren't</em> just taken as literal are:<br> <ul> <li>Quotes. Contrary to what might be popular belief, quotes don't "enclose a string" or anything like that. <em class="text-italics">Everything</em> in the attribute value is a string, unless it's parsable as a number or is precisely one of the fixed strings yes/no/true/false. Quotes do three things: they disable the whitespace-collapsing behaviour of unquoted text, and they prevent a newline character from terminating the attribute value. Lastly, they prevent most other characters from being treated specially, with the exception of curly braces (which are still treated as macro inclusions) and the quote character itself (which terminates the quoted passage, unless it's doubled, which expands to a single double quote character and continues the quoted passage). So they're an escaping mechanism, comparable to <code class="inline-code"><![CDATA[....]]></code> in XML.</li> <li>Double left angle brackets <code class="inline-code"><<</code>. These are <em class="text-italics">almost</em> semantically identical to quotes, but curly braces and quotes within them are not treated as special characters, whereas double right angle brackets <code class="inline-code">>></code> <em class="text-italics">are</em>, terminating the quoted passage.</li> <li>Plus signs. These have two use-cases. One is as a line-continuation character – if the last non-comment non-whitespace character on the line is a plus sign, the attribute value continues onto the next line. The second use-case comes into play only when placed between two quoted passages. Without a plus sign, a space would be inserted between the two quoted passages; the plus sign prevents this from happening.</li> <li>Number signs. As you probably know, a number sign begins a comment, which means the end of the attribute value unless directly preceded by a plus sign.</li> <li>Commas. These only have a special meaning if they appear outside quotes <em class="text-italics">and</em> the left-hand side of the <code class="inline-code">=</code> contained commas. The value is split on the unquoted commas and assigned to each of the attributes in turn, with the last attribute getting any extra parts (with the commas themselves left in).</li> <li>Underscores. This only has a special meaning when directly preceding a quoted passage (either with actual quotes or with angled brackets), which will then be marked as translatable.</li> </ul> (Note that I've omitted <code class="inline-code">$</code>, since that only comes into play long after the parsing has finished.)<br> <br> And the reason the above code passage works and the below one doesn't is because (from what I can tell) the parser chokes if the character after a quoted passage is not a whitespace character. (Although I haven't tested the below snippet, and it's possible that it's <em class="text-italics">only</em> the newlines that make the original snippet fail.)<br> <div class="codebox"><p>Code: <a href="#" onclick="selectCode(this); return false;">Select all</a></p><pre><code>#define MY_FORMULA "(if(a = b, 12, 22))"#enddef </code></pre></div></div> <div id="sig688790" class="signature">Author of <a href="http://r.wesnoth.org/t37342" class="postlink">The Black Cross of Aleron</a> campaign and <a href="http://r.wesnoth.org/t37417" class="postlink">Default++</a> era.<br> Former maintainer of <a href="http://r.wesnoth.org/t26527" class="postlink">Steelhive</a>.</div> </div> </div> <div class="back2top"> <a href="#top" class="top" title="Top"> <i class="icon fa-chevron-circle-up fa-fw icon-gray" aria-hidden="true"></i> <span class="sr-only">Top</span> </a> </div> </div> </div> <div id="p688799" class="post has-profile bg2"> <div class="inner"> <dl class="postprofile" id="profile688799"> <dt class="no-profile-rank no-avatar"> <div class="avatar-container"> </div> <a href="./memberlist.php?mode=viewprofile&u=271897&sid=5da6f13e50f54da5b92352201d076ba6" class="username">Duke_Anax</a> </dt> <dd class="profile-posts"><strong>Posts:</strong> <a href="./search.php?author_id=271897&sr=posts&sid=5da6f13e50f54da5b92352201d076ba6">62</a></dd> <dd class="profile-joined"><strong>Joined:</strong> March 29th, 2024, 10:50 pm</dd> </dl> <div class="postbody"> <div id="post_content688799"> <h3 > <a href="./viewtopic.php?p=688799&sid=5da6f13e50f54da5b92352201d076ba6#p688799">Re: Seeking tricky WML examples</a> </h3> <ul class="post-buttons"> <li> <a href="./posting.php?mode=quote&p=688799&sid=5da6f13e50f54da5b92352201d076ba6" title="Reply with quote" class="button button-icon-only"> <i class="icon fa-quote-left fa-fw" aria-hidden="true"></i><span class="sr-only">Quote</span> </a> </li> </ul> <p class="author"> <a class="unread" href="./viewtopic.php?p=688799&sid=5da6f13e50f54da5b92352201d076ba6#p688799" title="Post"> <i class="icon fa-file fa-fw icon-lightgray icon-md" aria-hidden="true"></i><span class="sr-only">Post</span> </a> <span class="responsive-hide">by <strong><a href="./memberlist.php?mode=viewprofile&u=271897&sid=5da6f13e50f54da5b92352201d076ba6" class="username">Duke_Anax</a></strong> » </span><time datetime="2024-04-17T05:50:04+00:00">April 17th, 2024, 5:50 am</time> </p> <div class="content">Thanks for the explanation, that makes a lot of things much clearer.
