  toquet [options] -e QUERY-STRING [QUERY-BASE-URI]
  toquet [options] --describe URI

  Options:
    --exec Q, -e Q        Provide query as a string
    --describe U          Describe URI <U>
    --input L, -i L       Set query language to L
    --output F, -o F      Set result format to F
    --endpoint U, -E U    SPARQL Protocol endpoint
    --data U, -D U        Data to query
    --named U, -G U       Named graph to query
    --dump-query F, -d F  Dump query in format F
    --count, -c           Count results only
    --quiet, -q           No extra information messages
    --help, -h            Show this help

  Dump formats: sparql, sse, parsed, pattern.
```

## OPTIONS

- **--exec**, **-e**

  Provides the string to use as a query. May be in SPARQL or RDQL. (RDQL is even supported on remote endpoints which only speak SPARQL!)

  If omitted, a query URI must be provided instead. This URI will be dereferenced (fetched) and a query is expected to be found inside (the HTTP Content-Type header is ignored).

  The query base URI may be provided to allow the resolution of any relative URI references in the query.

- **--describe**

  Request a description of a particular URI. This overrides **--exec**. Multiple URIs can be provided.

- **--input**

  Query language. Default is 'sparql11' (SPARQL 1.1). Others are 'sparql' (SPARQL 1.0) and 'rdql'.

- **--results**, **-r**, **--output**, **-o**

  Specifies the output format. The synopsis of this manual page shows a list of input formats. Some output formats require Spreadsheet::Wright and additional modules to be installed.

  Defaults are 'ntriples' (for graphs) and 'text' (for bindings and booleans).

- **--endpoint**, **-E**

  A SPARQL Protocol 1.0 endpoint to query.

- **--data**, **-D**

  Adds data from a URL to the default (unnamed) graph to be queried.

  This option can be used multiple times, but cannot be used in conjunction with --endpoint.

- **--named**, **-G**, **--source**, **-s**

  Adds data from a URL to a named graph to be queried.

  This option can be used multiple times, but cannot be used in conjunction with --endpoint.

- **--dump-query**, **-d**

  Dump the query itself (not the results).

  Queries can be dumped as a SPARQL string (useful for interpolating relative URIs, or converting from RDQL), or as SSE. The parsed query (or just the graph pattern within it) can be dumped in YAML.

- **--count**, **-c**

  Suppresses the output of the data, and just shows a count of triples/bindings instead.

  Boolean results (i.e. ASK queries) always return a count of 1.

- **--quiet**, **-q**

  Hides useless debugging messages.

- **--help**, **-h**

  Shows a short help message.

- **--version**, **-v**

  Shows the version of various Perl modules used by toquet. toquet itself doesn't have a version number, but is distributed along with RDF::TrineShortcuts, so could be considered to have the same version number as that.

## SHEBANG!!

toquet can be used as a shebang line of a SPARQL query file. e.g.:

```
  #!/usr/local/bin/toquet OPTS: -E http://dbpedia.org/sparql -o json

  PREFIX foaf: <http://xmlns.com/foaf/0.1/>
  SELECT ?person ?name
  WHERE
  {
     ?person a foaf:Person ;
        foaf:name ?name .
  }
```

Note that you need the "OPTS:" bit to pass command-line options. This is a workaround for a limitation in Linux's shebang handling.

## NOTE

When possible, toquet attempts to use the same command-line options as the 'roqet' tool that is distributed with librasqal. However, full compatibility with roqet is not a goal, and is certainly not guaranteed.

A toquet is a small bonnet-like hat.
