+
+20210720 v1.16.0
+- Note to Package Maintainers:
+    TL;DR: `/man/jc.1.gz` and `/jc/man/jc.1.gz` are deprecated and only `/man/jc.1` should be used.
+    
+    The Man page in the PyPi source packages will be moving from `/jc/man/jc.1.gz` to `/man/jc.1`
+    in version 1.17.0. For now the Man pages will be available in both locations, but be aware that
+    the Man page at `/jc/man/jc.1.gz` is now considered deprecated.
+
+    Also, starting in v1.17.0, the Man page will no longer be compressed in the source package,
+    therefore `/man/jc.1.gz` should also be considered deprecated and will no longer be available
+    after v1.17.0. Please use `/man/jc.1` and compress downstream if you would like.
+- Include CHANGELOG in source distribution
+- Fix Man page location in source packages
+- Add sfdisk command parser tested on linux
+- Update unit test files to change the timezone when needed (POSIX only)

 - Try to keep the schema as flat as possible - typically a list of flat dictionaries

+## Tests
+It is essential to have good command output sample coverage and tests to keep the `jc` parser quality high.
+
+Many parsers include calculated timestamp fields using the `jc.utils.timestamp` class. Naive timestamps created with this class should be generated on a system configured with the "**America/Los_Angeles**" timezone on linux/macOS/unix and "**Pacific Standard Time**" timezone on Windows for tests to pass on the Github Actions CI tests. This timezone should be configured on your local system before running the tests locally, as well.

 # JC
 JSON CLI output utility

 `jc` JSONifies the output of many CLI tools and file-types for easier parsing in scripts. See the [**Parsers**](#parsers) section for supported commands and file-types.
-
-This allows further command-line processing of output with tools like `jq` by piping commands:
 ```bash
-ls -l /usr/bin | jc --ls | jq '.[] | select(.size > 50000000)'
+dig example.com | jc --dig
 ```
 ```json

-Two representations of the data are possible. The default representation uses a strict schema per parser and converts known numbers to int/float JSON values. Certain known values of `None` are converted to JSON `null`, known boolean values are converted, and, in some cases, additional semantic context fields are added.
-
-> Note: Some parsers have calculated epoch timestamp fields added to the output. Unless a timestamp field name has a `_utc` suffix it is considered naive. (i.e. based on the local timezone of the system the `jc` parser was run on). 
->
-> If a UTC timezone can be detected in the text of the command output, the timestamp will be timezone aware and have a `_utc` suffix on the key name. (e.g. `epoch_utc`) No other timezones are supported for aware timestamps.

+### Streaming Parsers
+Most parsers load all of the data from STDIN, parse it, then output the entire JSON document serially. There are some streaming parsers (e.g. `ls-s` and `ping-s`) that immediately start processing and outputing the data line-by-line as [JSON Lines](https://jsonlines.org/) (aka [NDJSON](http://ndjson.org/)) while it is being received from STDIN. This can significantly reduce the amount of memory required to parse large amounts of command output (e.g. `ls -lR /`) and can sometimes process the data more quickly. Streaming parsers have slightly different behavior than standard parsers as outlined below.
+
+> Note: Streaming parsers cannot be used with the "magic" syntax
+
+#### Ignoring Errors
+
+You may want to ignore parsing errors when using streaming parsers since these may be used in long-lived processing pipelines and errors can break the pipe. To ignore parsing errors, use the `-qq` cli option or the `ignore_exceptions=True` argument with the `parse()` function. This will add a `_jc_meta` object to the JSON output with a `success` attribute. If `success` is `true`, then there were no issues parsing the line. If `success` is `false`, then a parsing issue was found and `error` and `line` fields will be added to include a short error description and the contents of the unparsable line, respectively:
+
+Successfully parsed line with `-qq` option:
+```json
+{
+  "command_data": "data",
+  "_jc_meta": {
+    "success": true
+  }
+}
+```
+Unsuccessfully parsed line with `-qq` option:
+```json
+{
+  "_jc_meta": {
+    "success": false,
+    "error": "error message",
+    "line": "original line data"
+  }
+}
+```
+
+#### Unbuffering Output
+
+Most operating systems will buffer output that is being piped from process to process. The buffer is usually around 4KB. When viewing the output in the terminal the OS buffer is not engaged so output is immediately displayed on the screen. When piping multiple processes together, though, it may seem as if the output is hanging when the input data is very slow (e.g. `ping`):
+```
+$ ping 1.1.1.1 | jc --ping-s | jq
+<slow output>
+```
+This is because the OS engages the 4KB buffer between `jc` and `jq` in this example. To display the data on the terminal in realtime, you can disable the buffer with the `-u` (unbuffer) cli option:
+```
+$ ping 1.1.1.1 | jc --ping-s -u | jq
+{"type":"reply","pattern":null,"timestamp":null,"bytes":"64","response_ip":"1.1.1.1","icmp_seq":"1","ttl":"128","time_ms":"24.6","duplicate":false}
+{"type":"reply","pattern":null,"timestamp":null,"bytes":"64","response_ip":"1.1.1.1","icmp_seq":"2","ttl":"128","time_ms":"26.8","duplicate":false}
+...
+```
+> Note: Unbuffered output can be slower for large data streams.
+
+#### Using Streaming Parsers as Python Modules
+
+Streaming parsers accept any iterable object and return a generator iterator object allowing lazy processing of the data. The input data should iterate on lines of string data. Examples of good input data are `sys.stdin` or `str.splitlines()`.
+
+To use the generator object in your code, simply loop through it or use the [next()](https://docs.python.org/3/library/functions.html#next) builtin function:
+```python
+import jc.parsers.ls_s
+
+result = jc.parsers.ls_s.parse(ls_command_output.splitlines())
+for item in result:
+    print(item["filename"])
+```

 Local parser plugins are standard python module files. Use the [`jc/parsers/foo.py`](https://github.com/kellyjonbrazil/jc/blob/master/jc/parsers/foo.py) parser as a template and simply place a `.py` file in the `jcparsers` subfolder.

 > Note: The application data directory follows the [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html)

+### Caveats
+
+#### Locale
+
+For best results set the `LANG` locale environment variable to `C` or `en_US.UTF-8`. For example, either by setting directly on the command-line:
+```
+$ LANG=C date | jc --date
+```
+or by exporting to the environment before running commands:
+```
+$ export LANG=C
+```
+
+#### Timezones
+
+Some parsers have calculated epoch timestamp fields added to the output. Unless a timestamp field name has a `_utc` suffix it is considered naive. (i.e. based on the local timezone of the system the `jc` parser was run on).
+
+If a UTC timezone can be detected in the text of the command output, the timestamp will be timezone aware and have a `_utc` suffix on the key name. (e.g. `epoch_utc`) No other timezones are supported for aware timestamps.
+
 ## Compatibility
-Some parsers like `ls`, `ps`, `dig`, etc. will work on any platform. Other parsers that are platform-specific will generate a warning message if they are used on an unsupported platform. To see all parser information, including compatibility, run `jc -ap`.

- `-h`: File sizes will be available in text form with `-r` but larger file sizes with human readable suffixes will be converted to `Null` in the default view since the parser attempts to convert this field to an integer.

 Note: The `-1`, `-l`, or `-b` option of `ls` should be used to correctly parse filenames that include newline characters. Since `ls` does not encode newlines in filenames when outputting to a pipe it will cause `jc` to see multiple files instead of a single file if `-1`, `-l`, or `-b` is not used. Alternatively, `vdir` can be used, which is the same as running `ls -lb`.

+# jc.parsers.ping_s
+jc - JSON CLI output utility `ping` command output streaming parser
+
+> This streaming parser outputs JSON Lines
+
+Supports `ping` and `ping6` output.
+
+Usage (cli):
+
+    $ ping | jc --ping-s
+
+> Note: When piping `jc` converted `ping` output to other processes it may appear the output is hanging due to the OS pipe buffers. This is because `ping` output is too small to quickly fill up the buffer. Use the `-u` option to unbuffer the `jc` output if you would like immediate output. See the [readme](https://github.com/kellyjonbrazil/jc/tree/master#unbuffering-output) for more information.
+
+Usage (module):
+
+    import jc.parsers.ping_s

+# jc.parsers.systeminfo
+jc - JSON CLI output utility `systeminfo` command output parser
+
+Blank or missing elements are set to `null`.
+
+The `original_install_date_epoch` and `system_boot_time_epoch` calculated timestamp fields are naive (i.e. based on the local time of the system the parser is run on)
+
+The `original_install_date_epoch_utc` and `system_boot_time_epoch_utc` calculated timestamp fields are timezone-aware and are only available if the timezone field is UTC.
+
+Usage (cli):
+
+    $ systeminfo | jc --systeminfo
+
+Usage (module):
+
+    import jc.parsers.systeminfo
+    result = jc.parsers.systeminfo.parse(systeminfo_command_output)

+# jc.parsers.ufw_appinfo
+jc - JSON CLI output utility `ufw app info [application]` command output parser
+
+Supports individual apps via `ufw app info [application]` and all apps list via `ufw app info all`.
+
+Because `ufw` application definitions allow overlapping ports and port ranges, this parser preserves that behavior, but also provides `normalized` lists and ranges that remove duplicate ports and merge overlapping ranges.
+
+Usage (cli):
+
+    $ ufw app info OpenSSH | jc --ufw-appinfo
+
+    or
+
+    $ jc ufw app info OpenSSH

+# jc.parsers.vmstat_s
+jc - JSON CLI output utility `vmstat` command output streaming parser
+
+> This streaming parser outputs JSON Lines
+
+Options supported: `-a`, `-w`, `-d`, `-t`
+
+The `epoch` calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on)
+
+The `epoch_utc` calculated timestamp field is timezone-aware and is only available if the timezone field is UTC.
+
+Usage (cli):
+
+    $ vmstat | jc --vmstat-s
+
+> Note: When piping `jc` converted `vmstat` output to other processes it may appear the output is hanging due to the OS pipe buffers. This is because `vmstat` output is too small to quickly fill up the buffer. Use the `-u` option to unbuffer the `jc` output if you would like immediate output. See the [readme](https://github.com/kellyjonbrazil/jc/tree/master#unbuffering-output) for more information.
+
+Usage (module):
+
+    import jc.parsers.vmstat_s
+    result = jc.parsers.vmstat_s.parse(vmstat_command_output.splitlines())    # result is an iterable object
+    for item in result:

+"""jc - JSON CLI output utility `csv` file streaming parser
+
+> This streaming parser outputs JSON Lines
+
+The `csv` streaming parser will attempt to automatically detect the delimiter character. If the delimiter cannot be detected it will default to comma. The first row of the file must be a header row.
+
+Note: The first 100 rows are read into memory to enable delimiter detection, then the rest of the rows are loaded lazily.
+
+Usage (cli):
+
+    $ cat file.csv | jc --csv-s
+
+Usage (module):
+
+    import jc.parsers.csv_s
+    result = jc.parsers.csv_s.parse(csv_output)
+
+Schema:
+
+    csv file converted to a Dictionary: https://docs.python.org/3/library/csv.html
+
+    {
+      "column_name1":     string,
+      "column_name2":     string
+    }

+
+    $ cat homes.csv
+    "Sell", "List", "Living", "Rooms", "Beds", "Baths", "Age", "Acres", "Taxes"

 Options supported:
 - `lbaR1`
 - `--time-style=full-iso`
- `-h`: File sizes will be available in text form with `-r` but larger file sizes with human readable suffixes will be converted to `Null` in the default view since the parser attempts to convert this field to an integer.

 Note: The `-1`, `-l`, or `-b` option of `ls` should be used to correctly parse filenames that include newline characters. Since `ls` does not encode newlines in filenames when outputting to a pipe it will cause `jc` to see multiple files instead of a single file if `-1`, `-l`, or `-b` is not used. Alternatively, `vdir` can be used, which is the same as running `ls -lb`.
