    <p>I m trying to make a .smil (.xml) parser in javascript. But when I want to test it, node.js just say me that:</p> <pre><code>buffer.js:246 switch(encoding &amp;&amp; encoding.toLowerCase()){ ^ TypeError: Object 1 has no method 'toLowerCase' at Function.Buffer.isEncoding (buffer.js:246:32) at assertEncoding (fs.js:98:27) at Object.fsread (fs.js:422:5) at gets (/home/pi/SMIL_Parser.js:8:8) at read_until (/home/pi/SMIL_Parser.js:28:14) at home/pi/SMIL_Parser.js:64:14 at Object.oncomplete (fs.js:93.15) </code></pre> <p>gets () is indeed one of my function:</p> <pre><code>var io=require('fs'); ... function gets (file){ var chaine="", cache="", pkmn=0; io.read(file, cache, 0, 1, null, function(err, byte, buf){ if (err || byte===0){return -1;} while ((cache!=="\n")) { chaine=chaine+cache; cache=""; pkmn=io.readSync(file, cache, 0, 1, null); if (pkmn===0){return -1;} } }); } </code></pre> <p>I just don t have any idea of what go wrong, it seem to be read, but I ve made sure to get the right arguments, tried to update node.js, fs and npm. And the only similar error I found on google was a update problem.</p> <p>EDIT: Added the complete error message, here function read_until:</p> <pre><code>function read_until(smil, limit){ var line=""; do { line=gets(smil); if (line===-1){return -1} }while (!(line.search(limit))); return 0; } </code></pre> <p>.</p> <pre><code>function parse (pathname){ var smil=0, line="", pkmn=0; io.open(pathname, 'r', function (err, fd){ if (err){return -1;} smil=fd; pkmn=read_until(smil, "&lt;smil&gt;"); ... </code></pre>

    1. COIt would appear that type of "encoding" is not a string.

    3. COYou should be able to see in your stack trace, which line is producing the call. If we know which line in your 'gets' function is resulting in the call to Function.Buffer.isEncoding, we could help more. Or rather, a line like this: Object.fsread (fs.js:422:5). Except, instead of fs.js:422:5 we want the first line that matches the name of a file you've developed, it should match the file that contains your "gets" function.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
