Csvtk - Filter2 Help
--------------------

Info
####

Csvtk advanced filter (also called filter2) outputs rows that satisfy the input awk-like artithmetic/string expressions. Please see the
`documentation <https://github.com/Knetic/govaluate/blob/master/MANUAL.md>`_ for further details and examples on how to write expressions.

.. class:: warningmark

    Single quotes are not allowed in text inputs!

.. class:: note

    If your wanted column header has a space in it, use the column number. Example: Use $1 if column #1 is called "Colony Counts"

Supported operators and types:

    - Modifiers: + - / * & | ^ ** % >> <<
    - Comparators: > >= < <= == != =~ !~
    - Logical ops: || &&
    - Numeric constants, as 64-bit floating point (12345.678)
    - String constants (double quotes: "foobar")
    - Date constants (double quotes)
    - Boolean constants: true false
    - Parenthesis to control order of evaluation ( )
    - Arrays (anything separated by , within parenthesis: (1, 2, "foo"))
    - Prefixes: ! - ~
    - Ternary conditional: ? :
    - Null coalescence: ??

Usage
#####

**Ex. Filter2 on one column:**

Suppose we had the following table:

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| ECo-1         | 2523       | 1000     |
+---------------+------------+----------+
| LPn-1         | 100        | 1000000  |
+---------------+------------+----------+
| LPn-2         | 4          | 1000     |
+---------------+------------+----------+

If we wanted to find all samples with the label LPn, we could use the filter expression '$1 =~ "LPn*"' to get the following output:

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| LPn-1         | 100        | 1000000  |
+---------------+------------+----------+
| LPn-2         | 4          | 1000     |
+---------------+------------+----------+

Note how $1 was used to get column 1 due to it containing a space

----

**Ex2. Filter2 with multiple inputs:**

Same input table

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| ECo-1         | 2523       | 1000     |
+---------------+------------+----------+
| LPn-1         | 100        | 1000000  |
+---------------+------------+----------+
| LPn-2         | 4          | 1000     |
+---------------+------------+----------+

Now if we use the expression '$1 =~ "LPn*" && $Dilution > 1000' to filter on, we would pull out the only row that satisfies both conditions:

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| LPn-1         | 100        | 1000000  |
+---------------+------------+----------+
