A compliant POM parser should not + reject any file in any other case, outside of exceptional circumstances such as running out of memory. + When an error occurs, it should be reported, ideally with information about the file name and line number, + and the file must be entirely rejected (i.e. parsers must not attempt to preserve only the correct parts of an erroneous file). + Warnings may also be issued according to the judgment of the library author. +</p> +<h2>Text encoding</h2> +<p> + All POM files are encoded using UTF-8. Both LF and CRLF line endings may be used (see below). + If invalid UTF-8 is encountered, including overlong sequences and UTF-16 surrogate halves (U+D800-DFFF), + an error occurs. +</p> +<h2>Valid keys/values</h2> +<p> + Keys in a POM file may contain the following characters +</p> +<ul> + <li> + The ASCII characters <code>a</code>–<code>z</code>, <code>A</code>–<code>Z</code>, <code>0</code>–<code>9</code>, as well as each of + <code>./-+*_</code>. + </li> + <li> + Any non-ASCII code point (U+0080–10FFFF). + </li> +</ul> +<p> + A non-empty string containing only these characters is a valid key if and only if it does not start or end with a dot + and does not contain two dots in a row (<code>..</code>). +</p> +<p> + Any string of non-zero Unicode code points (U+0001–U+10FFFF) is a valid value. +</p> +<h2>Parsing</h2> +<p> + If a “byte order mark” of <code>EF BB BF</code> appears at the start of the file, + it is ignored. + Every carriage return character (U+000D) which immediately precedes a line feed (U+000A) is deleted. + Then, if any control characters in the range U+0000 to U+001F other than the line feed and horizontal + tab (U+0009) are present in the file, an error occurs. +</p> +<p> + The <i>current-section</i> is a string variable which should be maintained during parsing. It is initally + equal to the empty string. +</p> +<p> + An <i>accepted-space</i> is either a space (U+0020) or horizontal tab (U+0009) character. +</p> +<p> + Parsing now proceeds line-by-line, with lines being delimited by line feed characters. For each line: +</p> +<ol> + <li>Any accepted-spaces that appear at the start of the line are removed.</li> + <li> + If the line begins with <code>#%disable warnings</code> or <code>#%enable warnings</code>, + warnings should be disabled/enabled if any are implemented. + </li> + <li> + If the line is empty or begins with <code>#</code>, + parsing proceeds to the next line. + </li> + <li> + If the line begins with <code>[</code>, it is interpreted as a <i>section header</i>. In this case: + <ol> + <li>If the line does not end with <code>]</code> optionally succeeded by any number of accepted-spaces, an error occurs.</li> + <li> + The current-section is set to the text in between the initial <code>[</code> and final <code>]</code> + (white space between the <code>[</code> and <code>]</code> is <em>not</em> trimmed). + </li> + <li> + If the new current-section is not empty and not a valid key (see above), an error occurs. + </li> + </ol> + </li> + <li> + Otherwise, the line is now interpreted as a key-value assignment. In this case: + <ol> + <li>If the line does not contain an equal sign (<code>=</code>), an error occurs.</li> + <li> + The <i>relative-key</i> is the text preceding the <code>=</code>, not including any space or horizontal tab characters + immediately before the <code>=</code>. + </li> + <li> + If the relative-key is not a valid key (see above), an error occurs. + </li> + <li> + Let <i>c</i> be the first character after the <code>=</code> and any succeeding accepted-spaces. + </li> + <li> + If <i>c</i> is one of <code>"'`</code> (U+0022 QUOTATION MARK, U+0027 APOSTROPHE, U+0060 GRAVE ACCENT), + the value is <i>quoted</i>, and spans from the first character after <i>c</i> to the next unescaped + instance of <i>c</i> in the file (which may be on a different line). In this case, + <ol> + <li> + Escape sequences are processed as described below. + </li> + <li> + Following the closing instance of <i>c</i>, there must be a line feed, + optionally preceded by any number of accepted-spaces; + otherwise an error occurs. + </li> + </ol> + </li> + <li> + Otherwise, accepted-spaces at the end of the line are removed; + then, the value is the text starting from <i>c</i> and ending at the next line feed. + </li> + <li>If the value is not a valid value (see above), an error occurs.</li> + <li> + The key is equal to the relative-key if the current-section is empty; otherwise, it is equal to + the concatenation of current-section, a dot, and the relative-key. + </li> + <li> + The key is assigned to the value. + </li> + </ol> + </li> +</ol> + +<h2>Escape sequences</h2> + +<p> + POM defines the following escape sequences, which may appear in quoted values. + If a backslash character occurs in a quoted value but does not form + a defined escape sequence, an error occurs. +</p> + +<table> + <thead> + <tr><th>Escape sequence</th><th>Value</th></tr> + </thead> + <tbody> + <tr><td><code>\n</code></td><td>Line feed (U+000A)</td></tr> + <tr><td><code>\r</code></td><td>Carriage return (U+000D)</td></tr> + <tr><td><code>\t</code></td><td>Horizontal tab (U+0009)</td></tr> + <tr><td><code>\\</code></td><td>Literal <code>\</code> (U+005C)</td></tr> + <tr><td><code>\"</code></td><td>Literal <code>"</code> (U+0022)</td></tr> + <tr><td><code>\'</code></td><td>Literal <code>'</code> (U+0027)</td></tr> + <tr><td><code>\`</code></td><td>Literal <code>`</code> (U+0060)</td></tr> + <tr><td><code>\,</code></td><td>Literal <code>\,</code> (U+005C U+002C)</td></tr> + <tr><td><code>\x</code><i>NM</i></td> + <td>ASCII character with code <i>NM</i>, + <br>interpreted as hexadecimal + <br>(must be in the range 01–7F).</td> + </tr> + <tr><td><code>\u{</code><i>digits</i><code>}</code></td> + <td>Unicode code point <i>digits</i>,<br> + interpreted as hexidecimal<br> + <i>digits</i> must be 1–6 characters long,<br> + and may contain leading zeros,<br> + but must not be zero.</td> + </tr> + </tbody> +</table> + +<h2>Lists</h2> +<p> + Although POM does not have a way of specially designating a value as being a list, + there is a recommended syntax for encoding them.
