- *  \file synctex_parser.c
- *  \brief SyncTeX file parser and controller.
- *  - author: Jérôme LAURENS
- *  \version 1.21
- *  \date Sun Oct 15 15:09:55 UTC 2017
- *
- *  Reads and parse *.synctex[.gz] files,
- *  performs edit and display queries.
- *
- *  See
- *  - synctex_scanner_new_with_output_file
- *  - synctex_scanner_parse
- *  - synctex_scanner_free
- *  - synctex_display_query
- *  - synctex_edit_query
- *  - synctex_scanner_next_result
- *  - synctex_scanner_reset_result
- *
- *  The data is organized in a graph with multiple entries.
- *  The root object is a scanner, it is created with the contents on a synctex file.
- *  Each node of the tree is a synctex_node_t object.
- *  There are 3 subtrees, two of them sharing the same leaves.
- *  The first tree is the list of input records, where input file names are associated with tags.
- *  The second tree is the box tree as given by TeX when shipping pages out.
- *  First level objects are sheets and forms, containing boxes, glues, kerns...
- *  The third tree allows to browse leaves according to tag and line.

-/**
- *  Standard nodes refer to TeX nodes: math, kern, boxes...
- *  Proxy nodes are used to support forms.
- *  A form is parsed as a tree of standard nodes starting
- *  at the top left position.
- *  When a reference is used, the form is duplicated
- *  to the location specified by the reference.
- *  As the same form can be duplicated at different locations,
- *  the geometrical information is relative to its own top left point.
- *  As we need absolute locations, we use proxy nodes.
- *  A proxy node records an offset and the target node.
- *  The target partly acts as a delegate.
- *  The h and v position of the proxy node is the h and v
- *  position of the target shifted by the proxy's offset.
- *  The width, height and depth are not sensitive to offsets.
- *  When are proxies created ?
- *  1)  when the synctex file has been parsed, all the form refs
- *  are replaced by proxies to the content of a form.
- *  This content is a node with siblings (actually none).
- *  Those root proxies have the parent of the ref they replace,
- *  so their parents exist and are no proxy.
- *  Moreover, if they have no sibling, it means that their target have no
- *  sibling as well.
- *  Such nodes are called root proxies.
- *  2)  On the fly, when a proxy is asked for its child
- *  (or sibling) and has none, a proxy to its target's child
- *  (or sibling) is created if any. There are only 2 possible situations:
- *  either the newly created proxy is the child of a proxy,
- *  or it is the sibling of a proxy created on the fly.
- *  In both cases, the parent is a proxy with children.
- *  Such nodes are called child proxies.
- *  How to compute the offset of a proxy ?
- *  The offset of root proxy objects is exactly
- *  the offset of the ref they replace.
- *  The offset of other proxies is their owner's,
- *  except when pointing to a root proxy.
- *  What happens for cascading forms ?
- *  Here is an example diagram
- *
- *  At parse time, the arrow means "owns":
- *  sheet0 -> ref_to1
- *
- *            target1 -> ref_to2
- *
- *                       target2 -> child22
- *
- *  After replacing the refs:
- *  sheet0 -> proxy00 -> proxy01 -> proxy02
- *               |          |          |
- *            target1 -> proxy11 -> proxy12
- *                          |          |
- *                       target2 -> proxy22
- *
- *  proxy00, proxy11 and proxy22 are root proxies.
- *  Their offset is the one of the ref they replace
- *  proxy01, proxy02 and proxy12 are child proxies.
- *  Their proxy is the one of their parent.
- *  Optimization.
- *  After all the refs are replaced, there are only root nodes
- *  targeting standard node. We make sure that each child proxy
- *  also targets a standard node.
- *  It is possible for a proxy to have a standard sibling 
- *  whereas its target has no sibling at all. Root proxies
- *  are such nodes, and are the only ones.
- *  The consequence is that proxies created on the fly
- *  must take into account this situation.

-/*  The purpose of this function is to read a string.

- *  If a string was properly decoded, it is returned in value_ref and
- *  the cursor points to the new line marker.
- *  The returned string was alloced on the heap, the caller is the owner and
- *  is responsible to free it in due time,
- *  unless it transfers the ownership to another object.
- *  If no string is parsed, * value_ref is undefined.
- *  The maximum length of a string that a scanner can decode is platform dependent, namely UINT_MAX.
- *  If you just want to blindly parse the file up to the end of the current line,
- *  use _synctex_next_line instead.
- *  On return, the scanner cursor is unchanged if a string could not be scanned or
- *  points to the terminating '\n' character otherwise. As a consequence,
- *  _synctex_next_line is necessary after.
- *  If either scanner or value_ref is NULL, it is considered as an error and
