NAME

       tablify - turn a delimited text file into a text table

SYNOPSIS

         tablify [options] file

       Options:

         -h|--help           Show help
         -c|--comment        Define the beginning of a (single-line) comment
         -n|--no-headers     Assume first line is data, not headers
         --no-pager          Do not use $ENV{'PAGER'} even if defined
         --strip-quotes      Strip " or ' around fields
         -l|--list           List the fields in the file (for use with -f)
         -f|--fields=f1[,f2] Show only fields in comma-separated list;
                             when used in conjunction with "no-headers"
                             the list should be field numbers (starting at 1);
                             otherwise, should be field names
         -w|where=f<cmp>v    Apply the "cmp" Perl operator to restrict output
                             where field "f" matches the value "v";  acceptable
                             operators include ==, eq, >, >=, <=, and =~
         -v|--vertical       Show records vertically
         -i|--limit=n        Limit to given number of records
         --fs=x              Use "x" as the field separator
                             (default is tab "\t")
         --rs=x              Use "x" as the record separator
                             (default is newline "\n")
         --as-html           Create an HTML table instead of plain text
         --headers           Comma-separated list of names matching
                             the number of columns

DESCRIPTION

       This script is essentially a quick way to parse a delimited text file and view it as a
       nice ASCII table.  By selecting only certain fields, employing a where clause to only
       select records where a field matches some value, and using the limit to only see some of
       the output, you almost have a mini-database front-end for a simple text file.

EXAMPLES

       Given a data file like this:

         name,rank,serial_no,is_living,age
         George,General,190293,0,64
         Dwight,General,908348,0,75
         Attila,Hun,,0,56
         Tojo,Emporor,,0,87
         Tommy,General,998110,1,54

       To find the fields you can reference, use the list option:

         $ tablify --fs ',' -l people.dat
         +-----------+-----------+
         | Field No. | Field     |
         +-----------+-----------+
         | 1         | name      |
         | 2         | rank      |
         | 3         | serial_no |
         | 4         | is_living |
         | 5         | age       |
         +-----------+-----------+

       To extract just the name and serial numbers, use the fields option:

         $ tablify --fs ',' -f name,serial_no people.dat
         +--------+-----------+
         | name   | serial_no |
         +--------+-----------+
         | George | 190293    |
         | Dwight | 908348    |
         | Attila |           |
         | Tojo   |           |
         | Tommy  | 998110    |
         +--------+-----------+
         5 records returned

       To extract the first through third fields and the fifth field (where field numbers start
       at "1" -- tip: use the list option to quickly determine field numbers), use this syntax
       for fields:

         $ tablify --fs ',' -f 1-3,5 people.dat
         +--------+---------+-----------+------+
         | name   | rank    | serial_no | age  |
         +--------+---------+-----------+------+
         | George | General | 190293    | 64   |
         | Dwight | General | 908348    | 75   |
         | Attila | Hun     |           | 56   |
         | Tojo   | Emporor |           | 87   |
         | Tommy  | General | 998110    | 54   |
         +--------+---------+-----------+------+
         5 records returned

       To select only the ones with six serial numbers, use a where clause:

         $ tablify --fs ',' -w 'serial_no=~/^\d{6}$/' people.dat
         +--------+---------+-----------+-----------+------+
         | name   | rank    | serial_no | is_living | age  |
         +--------+---------+-----------+-----------+------+
         | George | General | 190293    | 0         | 64   |
         | Dwight | General | 908348    | 0         | 75   |
         | Tommy  | General | 998110    | 1         | 54   |
         +--------+---------+-----------+-----------+------+
         3 records returned

       To find Dwight's record, you would do this:

         $ tablify --fs ',' -w 'name eq "Dwight"' people.dat
         +--------+---------+-----------+-----------+------+
         | name   | rank    | serial_no | is_living | age  |
         +--------+---------+-----------+-----------+------+
         | Dwight | General | 908348    | 0         | 75   |
         +--------+---------+-----------+-----------+------+
         1 record returned

       To find the name of all the people with a serial number who are living:

         $ tablify --fs ',' -f name -w 'is_living==1' -w 'serial_no>0' people.dat
         +-------+
         | name  |
         +-------+
         | Tommy |
         +-------+
         1 record returned

       To filter outside of program and simply format the results, use "-" as the last argument
       to force reading of STDIN (and probably assume no headers):

         $ grep General people.dat | tablify --fs ',' -f 1-3 --no-headers -
         +---------+--------+--------+
         | Field1  | Field2 | Field3 |
         +---------+--------+--------+
         | General | 190293 | 0      |
         | General | 908348 | 0      |
         | General | 998110 | 1      |
         +---------+--------+--------+
         3 records returned

       When dealing with data lacking field names, you can specify "no-headers" and then refer to
       fields by number (starting at one), e.g.:

         $ tail -5 people.dat | tablify --fs ',' --no-headers -w '3 eq "General"' -
         +--------+---------+--------+--------+--------+
         | Field1 | Field2  | Field3 | Field4 | Field5 |
         +--------+---------+--------+--------+--------+
         | George | General | 190293 | 0      | 64     |
         | Dwight | General | 908348 | 0      | 75     |
         | Tommy  | General | 998110 | 1      | 54     |
         +--------+---------+--------+--------+--------+
         3 records returned

       If your file has many fields which are hard to see across the screen, consider using the
       vertical display with "-v" or "--vertical", e.g.:

         $ tablify --fs ',' -v --limit 1 people.dat
         ************ Record 1 ************
              name: George
              rank: General
         serial_no: 190293
         is_living: 0
              age : 64

         1 record returned

           Although I don't DBD::CSV this module, the idea was much the inspiration for this.  I
           just didn't want to have to install DBI and DBD::CSV to get this kind of
           functionality.  I think my interface is simpler.
