* Usage: java edu.stanford.nlp.trees.tregex.tsurgeon.Tsurgeon [-s] -treeFile file-with-trees [-po
* matching-pattern operation] operation-file-1 operation-file-2 ... operation-file-n
*
* <h4>Arguments:</h4>
*
* Each argument should be the name of a transformation file that contains a list of pattern and
* transformation operation list pairs. That is, it is a sequence of pairs of a {@link
* TregexPattern} pattern on one or more lines, then a blank line (empty or whitespace), then a
* list of transformation operations one per line (as specified by <b>Legal operation syntax</b>
* below) to apply when the pattern is matched, and then another blank line (empty or whitespace).
* Note the need for blank lines: The code crashes if they are not present as separators (although
* the blank line at the end of the file can be omitted). The script file can include comment
* lines, either whole comment lines or trailing comments introduced by %, which extend to the end
* of line. A needed percent mark can be escaped by a preceding backslash.
*
* <p>For example, if you want to excise an SBARQ node whenever it is the parent of an SQ node,
* and relabel the SQ node to S, your transformation file would look like this:
*
* <blockquote>
*
* <code>
* SBARQ=n1 < SQ=n2<br>
* <br>
* excise n1 n1<br>
* relabel n2 S
* </code>
*
* </blockquote>
*
* <p>
*
* <h4>Options:</h4>
*
* <ul>
* <li><code>-treeFile <filename></code> specify the name of the file that has the trees
* you want to transform.
* <li><code>-po <matchPattern> <operation></code> Apply a single operation to
* every tree using the specified match pattern and the specified operation. Use this option
* when you want to quickly try the effect of one pattern/surgery combination, and are too
* lazy to write a transformation file.
* <li><code>-s</code> Print each output tree on one line (default is pretty-printing).
* <li><code>-m</code> For every tree that had a matching pattern, print "before" (prepended as
* "Operated on:") and "after" (prepended as "Result:"). Unoperated trees just pass through
* the transducer as usual.
* <li><code>-encoding X</code> Uses character set X for input and output of trees.
* <li><code>-macros <filename></code> A file of macros to use on the tregex pattern.
* Macros should be one per line, with original and replacement separated by tabs.
* <li><code>-hf <headfinder-class-name></code> use the specified {@link HeadFinder} class
* to determine headship relations.
* <li><code>-hfArg <string></code> pass a string argument in to the {@link HeadFinder}
* class's constructor. <code>-hfArg</code> can be used multiple times to pass in multiple
* arguments.
* <li><code>-trf <TreeReaderFactory-class-name></code> use the specified {@link
* TreeReaderFactory} class to read trees from files.
* </ul>
*
* <h4>Legal operation syntax:</h4>
*
* <ul>
* <li><code>delete <name></code> deletes the node and everything below it.
* <li><code>prune <name></code> Like delete, but if, after the pruning, the parent has
* no children anymore, the parent is pruned too. Pruning continues to affect all ancestors
* until one is found with remaining children. This may result in a null tree.
* <li><code>excise <name1> <name2></code> The name1 node should either dominate
* or be the same as the name2 node. This excises out everything from name1 to name2. All
* the children of name2 go into the parent of name1, where name1 was.
* <li><code>relabel <name> <new-label></code> Relabels the node to have the new
* label. <br>
* There are three possible forms: <br>
* <code>relabel nodeX VP</code> - for changing a node label to an alphanumeric string <br>
* <code>relabel nodeX /''/</code> - for relabeling a node to something that isn't a valid
* identifier without quoting <br>
* <code>relabel nodeX /^VB(.*)$/verb\\/$1/</code> - for regular expression based
* relabeling. In this case, all matches of the regular expression against the node label
* are replaced with the replacement String. This has the semantics of Java/Perl's
* replaceAll: you may use capturing groups and put them in replacements with $n. For
* example, if the pattern is /foo/bar/ and the node matched is "foo", the replaceAll
* semantics result in "barbar". If the pattern is /^foo(.*)$/bar$1/ and node matched is
* "foofoo", relabel will result in "barfoo". <br>
* When using the regex replacement method, you can also use the sequences ={node} and
* %{var} in the replacement string to use captured nodes or variable strings in the
* replacement string. For example, if the Tregex pattern was "duck=bar" and the relabel is
* /foo/={bar}/, "foofoo" will be replaced with "duckduck". <br>
* To concatenate two nodes named in the tregex pattern, for example, you can use the
* pattern /^.*$/={foo}={bar}/. Note that the ^.*$ is necessary to make sure the regex
* pattern only matches and replaces once on the entire node name. <br>
* To get an "=" or a "%" in the replacement, using \ escaping. Also, as in the example you
* can escape a slash in the middle of the second and third forms with \\/ and \\\\. <br>
* <li><code>insert <name> <position></code> or <code>
* insert <tree> <position></code> inserts the named node or tree into the
* position specified.
* <li><code>move <name> <position></code> moves the named node into the
* specified position.
* <p>Right now the only ways to specify position are:
* <p><code>$+ <name></code> the left sister of the named node<br>
* <code>$- <name></code> the right sister of the named node<br>
* <code>>i <name></code> the i_th daughter of the named node<br>
* <code>>-i <name></code> the i_th daughter, counting from the right, of the
* named node.
* <li><code>replace <name1> <name2></code> deletes name1 and inserts a copy of
* name2 in its place.
* <li><code>replace <name> <tree> <tree2>...</code> deletes name and
* inserts the new tree(s) in its place. If more than one replacement tree is given, each of
* the new subtrees will be added in order where the old tree was. Multiple subtrees at the
* root is an illegal operation and will throw an exception.
* <li>{@code createSubtree <new-label> <name1> [<name2>]} Create a subtree out of all the nodes
* from {@code <name1>} through {@code <name2>} and puts the new subtree where that span
* used to be. To limit the operation to just one node, elide {@code <name2>}.
* <li><code>adjoin <auxiliary_tree> <name></code> Adjoins the specified auxiliary
* tree into the named node. The daughters of the target node will become the daughters of
* the foot of the auxiliary tree.
* <li><code>adjoinH <auxiliary_tree> <name></code> Similar to adjoin, but
* preserves the target node and makes it the root of <tree>. (It is still accessible
* as <code>name</code>. The root of the auxiliary tree is ignored.)
* <li><code>adjoinF <auxiliary_tree> <name></code> Similar to adjoin, but
* preserves the target node and makes it the foot of <tree>. (It is still accessible
* as <code>name</code>, and retains its status as parent of its children. The root of the
* auxiliary tree is ignored.)
* <li>
* <dt><code>coindex <name1> <name2> ... <nameM> </code> Puts a (Penn
* Treebank style) coindexation suffix of the form "-N" on each of nodes name_1 through
* name_m. The value of N will be automatically generated in reference to the existing
* coindexations in the tree, so that there is never an accidental clash of indices across
* things that are not meant to be coindexed.
* </ul>
*
* <p>In the context of <code>adjoin</code>, <code>adjoinH</code>, and <code>adjoinF</code>, an
* auxiliary tree is a tree in Penn Treebank format with <code>@</code> on exactly one of the
* leaves denoting the foot of the tree. The operations which use the foot use the labeled node.
* For example: <br>
* Tsurgeon: <code>adjoin (FOO (BAR@)) foo</code> <br>
* Tregex: <code>B=foo</code> <br>
* Input: <code>(A (B 1 2))</code> Output: <code>(A (FOO (BAR 1 2)))</code>
*
* <p>Tsurgeon applies the same operation to the same tree for as long as the given tregex
* operation matches. This means that infinite loops are very easy to cause. One common situation
* where this comes up is with an insert operation will repeats infinitely many times unless you
* add an expression to the tregex that matches against the inserted pattern. For example, this
* pattern will infinite loop:
*
* <blockquote>
*
* <code>
* TregexPattern tregex = TregexPattern.compile("S=node << NP"); <br>
* TsurgeonPattern tsurgeon = Tsurgeon.parseOperation("insert (NP foo) >-1 node");
* </code>
*
* </blockquote>
*
* This pattern, though, will terminate:
*
* <blockquote>
*
* <code>
* TregexPattern tregex = TregexPattern.compile("S=node << NP !<< foo"); <br>
* TsurgeonPattern tsurgeon = Tsurgeon.parseOperation("insert (NP foo) >-1 node");
* </code>
*
* </blockquote>
*
* <p>Tsurgeon has (very) limited support for conditional statements. If a pattern is prefaced
* with <code>if exists <name></code>, the rest of the pattern will only execute if the
* named node was found in the corresponding TregexMatcher.
*
* @param args a list of names of files each of which contains a single tregex matching pattern
* plus a list, one per line, of transformation operations to apply to the matched pattern.
* @throws Exception If an I/O or pattern syntax error

/**
* Prints out all matches of a tree pattern on each tree in the path. Usage: <br>
* <br>
* <code>
* java edu.stanford.nlp.trees.tregex.TregexPattern [[-TCwfosnu] [-filter] [-h <node-name>]]* pattern
* filepath </code>
*
* <p>Arguments:<br>
*
* <ul>
* <li><code>pattern</code>: the tree pattern which optionally names some set of nodes (i.e.,
* gives it the "handle") <code>=name</code> (for some arbitrary string "name")
* <li><code>filepath</code>: the path to files with trees. If this is a directory, there will
* be recursive descent and the pattern will be run on all files beneath the specified
* directory.
* </ul>
*
* <p>Options:<br>
* <li><code>-C</code> suppresses printing of matches, so only the number of matches is printed.
* <li><code>-w</code> causes the whole of a tree that matches to be printed.
* <li><code>-f</code> causes the filename to be printed.
* <li><code>-i <filename></code> causes the pattern to be matched to be read from <code>
* <filename></code> rather than the command line. Don't specify a pattern when this
* option is used.
* <li><code>-o</code> Specifies that each tree node can be reported only once as the root of a
* match (by default a node will be printed once for every <em>way</em> the pattern matches).
* <li><code>-s</code> causes trees to be printed all on one line (by default they are pretty
* printed).
* <li><code>-n</code> causes the number of the tree in which the match was found to be printed
* before every match.
* <li><code>-u</code> causes only the label of each matching node to be printed, not complete
* subtrees.
* <li><code>-t</code> causes only the yield (terminal words) of the selected node to be printed
* (or the yield of the whole tree, if the <code>-w</code> option is used).
* <li><code>-encoding <charset_encoding></code> option allows specification of character
* encoding of trees..
* <li><code>-h <node-handle></code> If a <code>-h</code> option is given, the root tree
* node will not be printed. Instead, for each <code>node-handle</code> specified, the node
* matched and given that handle will be printed. Multiple nodes can be printed by using the
* <code>-h</code> option multiple times on a single command line.
* <li><code>-hf <headfinder-class-name></code> use the specified {@link HeadFinder} class
* to determine headship relations.
* <li><code>-hfArg <string></code> pass a string argument in to the {@link HeadFinder}
* class's constructor. <code>-hfArg</code> can be used multiple times to pass in multiple
* arguments.
* <li><code>-trf <TreeReaderFactory-class-name></code> use the specified {@link
* TreeReaderFactory} class to read trees from files.
* <li><code>-v</code> print every tree that contains no matches of the specified pattern, but
* print no matches to the pattern.
* <li><code>-x</code> Instead of the matched subtree, print the matched subtree's identifying
* number as defined in <tt>tgrep2</tt>:a unique identifier for the subtree and is in the form
* s:n, where s is an integer specifying the sentence number in the corpus (starting with 1),
* and n is an integer giving the order in which the node is encountered in a depth-first
* search starting with 1 at top node in the sentence tree.
* <li><code>-extract <code> <tree-file></code> extracts the subtree s:n specified by
* <tt>code</tt> from the specified <tt>tree-file</tt>. Overrides all other behavior of
* tregex. Can't specify multiple encodings etc. yet.
* <li><code>-extractFile <code-file> <tree-file></code> extracts every subtree
* specified by the subtree codes in <tt>code-file</tt>, which must appear exactly one per
* line, from the specified <tt>tree-file</tt>. Overrides all other behavior of tregex. Can't
* specify multiple encodings etc. yet.
* <li><code>-filter</code> causes this to act as a filter, reading tree input from stdin
* <li><code>-T</code> causes all trees to be printed as processed (for debugging purposes).
* Otherwise only matching nodes are printed.
* <li><code>-macros <filename></code> filename with macro substitutions to use. file with
* tab separated lines original-tab-replacement
* </ul>
