Usage
Usage: qsel [command] [options] <url> [selector] | -
Example: qsel http://news.ycombinator.com ".title > a|bold|red" --limit 5
Options:
-T, --template <template> template "node: {{name}}, text {{.|text}}"
-l, --limit <count> limit query to count matches (-count from bottom) (default: 0)
-r, --rand select randomly from matched set (can be combined with --limit)
-j, --json full results object as (pretty) JSON
-c, --compact when used with --json, outputs compact format
-n, --line-number add line numbers to output
--request-options <request-options> options for "request" as relaxed JSON, "{foo: bar}"
-h, --help output usage information
-V, --version output the version number
Batch processing options:
- , --stdin read <url>(s) from STDIN
-o, --outfile <file> file to output to (default: stdout)
-q, --quite quite the logging
-p, --pause <seconds> pause between batch requests (default: 0.0 secs)
--sep <seperator> seperator for multiple matches (default: "\n")
--tag <tag> enclose complete result in <tag></tag>
Commands:
samples [N] show samples, or run sample N
help [what] get extra help with: pipes, selector, request-options Selectors
qsel supports all CSS3, some CSS4 and custom jQuery selectors like :contains(). For complete list see css-selelct, or run qsel help selector.
If no selector is given, the complete HTML of the page is returned.
Attributes
In general qsel returns the text() of the matched nodes. To select an attribute, add the x-ray-like @ to the selector (before the pipes!).
selector@<attr-name>- get an attribute by name, e.g.,selector@hrefselector@text- get text content of matched nodes recursively (default)selector@html- get the innerHTML
Multiple attributes are supported: selector@id@class.
Filters / Pipes
qsel supports Markup.js-type pipes separated by |, for example, selector|upcase, selector|pack|tease 7. For complete list see Markup.js' built-in pipes.
Need some emphasis or color? All chalk.styles are available as pipes as well: e.g. selector|red, selector|bold|bgBlue.
Additional pipes are defined in (src/pipes/basic.js):
|after text- add text after each match|before text- add text before each match|quote text- add text before and after each match|tag name- enclose match in <name> and </name>|incr N- increment the match value by N (default 1)|decr N- decrement the match value by N (default 1)|regex (foo.*)- match by regex|colorize- apply random chalk style to every line
Use \n to add a new line, e.g. selector|after \n\n. For complete list, run qsel help pipes.
Shell pipe
qsel can be forced to read from STDIN, either interactively or in a shell pipe, by providing the single dash option -. In this mode, each line of input is read as a url and executed in order. Each line may also contain its own selector. If none is given, the selector from the CLI is used.

For other examples, run qsel samples. (Note: samples are run using Node's child_process.exec() which gobbles colors in output streams. To see the colors, run the command directly from the shell.)
Run samples interactively
$ qsel samples
Choose a sample to run:

Custom HTTP headers
Any options for request can be entered in a relaxed jsonic format using --request-options.
$ qsel https://api.github.com/users/moos
Request forbidden by administrative rules. Please make sure your request has a User-Agent header (http://developer.github.com/v3/#user-agent-required). Check https://developer.github.com for other possible causes.

a term used as a universal substitute for something real, especially when discussing technological ideas and problemsPackage note
qsel relies on a fork of css-select which supplies the matched selector index in the list of matched elements. Since css-select is a dependency of cheerio, it ues npm shrinkwrap to load the fork. Any updates to cheerio will require manually updating the shrinkwrap json file. Hopefully with upcoming npm 3's flat dependency tree, this shebang can be eliminated.
