# jc.parsers.asciitable
jc - JSON Convert `asciitable` parser
This parser converts ASCII and Unicode text tables with single-line rows.
Column headers must be at least two spaces apart from each other and must
be unique. For best results, column headers should be left-justified. If
column separators are present, then non-left-justified headers will be fixed
automatically.
Row separators are optional and are ignored. Each non-row-separator line is
considered a separate row in the table.
For example:
╒══════════╤═════════╤════════╕
│ foo │ bar │ baz │
╞══════════╪═════════╪════════╡
│ good day │ │ 12345 │
├──────────┼─────────┼────────┤
│ hi there │ abc def │ 3.14 │
╘══════════╧═════════╧════════╛
or
+-----------------------------+
| foo bar baz |
+-----------------------------+
| good day 12345 |
| hi there abc def 3.14 |
+-----------------------------+
or
| foo | bar | baz |
|----------|---------|--------|
| good day | | 12345 |
| hi there | abc def | 3.14 |
or
foo bar baz
--------- -------- ------
good day 12345
hi there abc def 3.14
or
foo bar baz
good day 12345
hi there abc def 3.14
etc...
Headers (keys) are converted to snake-case. All values are returned as
strings, except empty strings, which are converted to None/null.
> Note: To preserve the case of the keys use the `-r` cli option or
> `raw=True` argument in `parse()`.
Usage (cli):
$ cat table.txt | jc --asciitable
Usage (module):
import jc
result = jc.parse('asciitable', asciitable_string)
Schema:
[
{
"column_name1": string, # empty string is null
"column_name2": string # empty string is null
}
]
Examples:
$ echo '
> ╒══════════╤═════════╤════════╕
> │ foo │ bar │ baz │
> ╞══════════╪═════════╪════════╡
> │ good day │ │ 12345 │
> ├──────────┼─────────┼────────┤
> │ hi there │ abc def │ 3.14 │
> ╘══════════╧═════════╧════════╛' | jc --asciitable -p
