<p class="MsoNormal">Dear LLVM engineers,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My name is Konstantin Rebrov. I am trying to recreate a simple program using YAML I/O to read *.yaml files into in-memory data structures, and write those same data structures back out into a *.yaml file.<o:p></o:p></p>
<p class="MsoNormal">I am following the official documentation/tutorial<o:p></o:p></p>
<p class="MsoNormal"><a href="https://llvm.org/docs/YamlIO.html">https://llvm.org/docs/YamlIO.html</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After compilation, my simple program successfully wrote the data structures into the output.yaml file. Then I tried to make input work, using that same output.yaml file as the input.yaml file.<o:p></o:p></p>
<p class="MsoNormal">Unfortunately my program failed to parse the YAML file correctly, reporting such an error:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="vertical-align:baseline"><span style="font-size:10.0pt;font-family:"inherit",serif;border:none windowtext 1.0pt;padding:0in">input_file2.yaml:1:1: error: not a sequence<o:p></o:p></span></p>
<p class="MsoNormal" style="vertical-align:baseline"><span style="font-size:10.0pt;font-family:"inherit",serif;border:none windowtext 1.0pt;padding:0in">-<o:p></o:p></span></p>
<p class="MsoNormal" style="vertical-align:baseline"><span style="font-size:10.0pt;font-family:"inherit",serif;border:none windowtext 1.0pt;padding:0in">^</span><span style="font-size:10.0pt;font-family:Consolas"><o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It reports this error for the first character in the file. Even if I remove the "---" at the top of the file, it would still omit that error.<o:p></o:p></p>
<p class="MsoNormal">I think that I am just missing one tiny detail, that I don’t know about yet. If there is anyone who has any some experience with YAML I/O, please help me solve this problem.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I wrote a detailed description of the exact error that I encountered, under what circumstances, and a full listing of my source code, in this StackOverflow post:<o:p></o:p></p>
