| # Explanation: | |
| # * `-v CHUNK_SIZE=128 -v CHUNK_OFFSET=0 -v CHUNK_COUNT=32` configures the process: | |
| # * 128 octets per chunk | |
| # * don't skip any leading chunks | |
| # * stop after outputting data for 32 chunks (i.e., 128×32=4 KiB of data) | |
| # * `LC_ALL=C` makes sure that numbers above 127 don't get transformed into multi-octet sequences. | |
| # * `--re-interval` and `RS=".{" CHUNK_SIZE "}"` expresses fixed-length records of CHUNK_SIZE octets. | |
| # * `OCTETS` is a string of all possible octets 0x00 through 0xFF in numerical order. | |
| # * `NR>CHUNK_OFFSET` only matches after the first CHUNK_OFFSET records. |

jQuery.xhr will be an asynchronous HTTP request API returning standards-compliant thenables. We have identified two possible approaches:
- Autosend: control by
optionsparameter; advanced functionality viabeforeSend(similar tojQuery.ajax) - Chainable: control by
optionsand/or chainable setters; advanced functionality viasend: falseand a chainablesendmethod
This gist compares the approaches by imagining their use for current jQuery.ajax examples. To better highlight differences, chaining methods will be used instead of options more heavily than is likely in actual practice (assuming that options is available in the "Chainable" solution).
