NAME

Table::Hack - The CLI commands for table pre-analysis are provided.

VERSION

Version 0.12

SYNOPSIS

This CPAN Module Table::Hack just essentially provides commands that run on CLI (command line interface), each is an independent program file written by Perl language. To know what they do can be known by the "--help" option switch after each command, and try running it without worrying.

Note that the following explaines only the main functions. Many minior function are not explained here, so using them by your hand is important. The author thinks from experiments, once you use it, you can easily understand what they do.

expskip  : only shows limited number of lines of a (big) text file
           by skipping excpet first 3 lines, last 3 lines, and 
           5, 10, 20, 50, 100, 200, .. -th lines. 

colorplus : colorizes text. With -3 option, it colorizes numbers.
            With -s option also with specifing regular exression
            the specified text are colorized. With -t option, 
            the columns background is colorized to help the 
            readability of text table with many columns. -b is 
            used to specify the color.

colsummary : It summarizes the character of all the columns of 
             a table. For each column, value range, frequent
             values, frequncy of them are summarized in a 
             readble way.

freq : It counts how many character strings deliminated by 
       line-end characters appear. The main function is 
       similar to "sort | uniq -c ", but it is much faster
       in almost cases and it provides various sub functions. 

sampler : line random sampler with specified possibility. 
          You can also choose the way of "sampling with
          replacement" and "sampling without replacement".
          You can specifiy the random seed so that you can 
          ensure the reproductivity.

csel : This is a column selector command even easier than
       AWK/cut. You can specify which columns to show by
       -p option, which columns to delete by -d, which columns 
       to be shown in the leftmost by -h, and which columns
       to be shown in the rightmost by -t. 

venn : This is to check the inclusion relations of multiple
       set. Useful to see which columns shares the same 
       coding system so that they can be connected by 
       table joining. 

crosstable : It provides 2-way contingency table for 
             2-columned table. 

latextable : yieldsa a latex table from a text table in 
             TSV format from (probably) any kind of characters. 

madeafter : given file names, this provides 3 time information
           (atime, mtime, ctime) by one-shot (so useful!)

colchop : Probably you have been annoyed by table text some cells
         of which contains long character strings. It chop off
         the long cells as you specify the maximum length.

saikoro : Random number generator of uniform distributions

transpose : performs matrix transpose.

csv2tsv : Transforms from CSV (RFC4180) into TSV format.
