Table::Hack - The CLI commands for table pre-analysis.
INSTALLATION
To install this module, run the following commands:
perl Build.PL
./Build
./Build test
./Build install
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 probablyovides 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.
