=head1 DESCRIPTION

This utility converts CSV format like this:

 name,email,phone,notes
 bill,bill@example.com,555-1236,+
 lisa,lisa@example.com,555-1235,from work
 jimmy,jimmy@example.com,555-1237,

into paragraphs format like this, which resembles (but not strictly follows)
email headers (RFC-822) or internet message headers (RFC-5322):

 name: bill
 email: bill@example.com
 phone: 555-1236
 notes: +
 
 name: lisa
 email: lisa@example.com
 phone: 555-1235
 notes: from work
 
 name: jimmy
 email: jimmy@example.com
 phone: 555-1237
 notes:

Why display in this format? It might be more visually readable or diff-able
especially if there are a lot of fields and/or there are long values.

If a CSV value contains newline, it will escaped "\n", e.g.:

 # CSV
 name,email,phone,notes
 beth,beth@example.com,555-1231,"Has no last name
 Might be adopted sometime by Jimmy"
 matthew,matthew@example.com,555-1239,"Quit
 
   or fired?"
 
 # paragraph
 name: beth
 email: beth@example.com
 phone: 555-1231
 notes: Has no last name\nMight be adopted sometime by Jimmy
 
 name: matthew
 email: matthew@example.com
 phone: 555-1239
 notes: Quit\n\n  or fired?

If a CSV value contains literal "\" (backslash) it will be escaped as "\".

Long lines are also by default folded at 78 columns (but you can customize with
the C<--width> option); if a line is folded a literal backslash is added to the
end of each physical line and the next line will be indented by two spaces:

 notes: This is a long note. This is a long note. This is a long note. This is
   a long note. This is a long note.

A long word is also folded and the next line will be indented by one space:

 notes: Thisisalongwordthisisalongwordthisisalongwordthisisalongwordthisisalongw
  ord

Newline and backslash are also escaped in header; additionally a literal ":"
(colon) is escaped into "\:".

There is option to skip displaying empty fields (C<--hide-empty-values>) and to
align the ":" header separator.

Keywords: paragraphs, cards, pages, headers

=head1 OPTIONS

C<*> marks required options.

=head2 Main options

=over

=item B<--align>

Whether to align header separator across lines.

Note that if you want to convert the paragraphs back to CSV later using
L<paras2csv>, the padding spaces added by this option will become part of
header value, unless you use its C<--trim-header> or C<--rtrim-header> option.


=item B<--hide-empty-values>

Whether to skip showing empty values.

=item B<--input-skip-num-lines>=I<s>

Number of lines to skip before header row.

This can be useful if you have a CSV files (usually some generated reports,
sometimes converted from spreadsheet) that have additional header lines or info
before the CSV header row.

See also the alternative option: C<--input-skip-until-pattern>.


=item B<--input-skip-until-pattern>=I<s>

Skip rows until the first header row matches a regex pattern.

This is an alternative to the C<--input-skip-num-lines> and can be useful if you
have a CSV files (usually some generated reports, sometimes converted from
spreadsheet) that have additional header lines or info before the CSV header
row.

With C<--input-skip-num-lines>, you skip a fixed number of lines. With this
option, rows will be skipped until the first field matches the specified regex
pattern.


=item B<--width>=I<s>

The width at which to fold long lines, -1 means to never fold.

Default value:

 78

=back

=head2 Input options

=over

=item B<--input-escape-char>=I<s>

Specify character to escape value in field in input CSV, will be passed to Text::CSV_XS.

Defaults to C<\\> (backslash). Overrides C<--input-tsv> option.


=item B<--input-filename>=I<s>

Input CSV file.

Default value:

 "-"

Use C<-> to read from stdin.

Encoding of input file is assumed to be UTF-8.


Can also be specified as the 1st command-line argument.

=item B<--input-quote-char>=I<s>

Specify field quote character in input CSV, will be passed to Text::CSV_XS.

Defaults to C<"> (double quote). Overrides C<--input-tsv> option.


=item B<--input-sep-char>=I<s>

Specify field separator character in input CSV, will be passed to Text::CSV_XS.

Defaults to C<,> (comma). Overrides C<--input-tsv> option.


=item B<--input-tsv>

Inform that input file is in TSV (tab-separated) format instead of CSV.

Overriden by C<--input-sep-char>, C<--input-quote-char>, C<--input-escape-char>
options. If one of those options is specified, then C<--input-tsv> will be
ignored.


=item B<--no-input-header>

Specify that input CSV does not have a header row.

By default, the first row of the input CSV will be assumed to contain field
names (and the second row contains the first data row). When you declare that
input CSV does not have header row (C<--no-input-header>), the first row of the
CSV is assumed to contain the first data row. Fields will be named C<field1>,
C<field2>, and so on.


=back

=head2 Logging options

=over

=item B<--debug>

Shortcut for --log-level=debug.

=item B<--log-level>=I<s>

Set log level.

By default, these log levels are available (in order of increasing level of
importance, from least important to most): C<trace>, C<debug>, C<info>,
C<warn>/C<warning>, C<error>, C<fatal>. By default, the level is usually set to
C<warn>, which means that log statements with level C<info> and less important
levels will not be shown. To increase verbosity, choose C<info>, C<debug>, or
C<trace>.

For more details on log level and logging, as well as how new logging levels can
be defined or existing ones modified, see L<Log::ger>.


=item B<--quiet>

Shortcut for --log-level=error.

=item B<--trace>

Shortcut for --log-level=trace.

=item B<--verbose>

Shortcut for --log-level=info.

=back

=head2 Output options

=over

=item B<--format>=I<s>

Choose output format, e.g. json, text.

Default value:

 undef

Output can be displayed in multiple formats, and a suitable default format is
chosen depending on the application and/or whether output destination is
interactive terminal (i.e. whether output is piped). This option specifically
chooses an output format.


=item B<--json>

Set output format to json.

=item B<--naked-res>

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

 [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd
element) as well as result metadata/extra result (4th element) instead of just
the result (3rd element). However, sometimes you want just the result, e.g. when
you want to pipe the result for more post-processing. In this case you can use
C<--naked-res> so you just get:

 [1,2,3]


=item B<--page-result>

Filter output through a pager.

This option will pipe the output to a specified pager program. If pager program
is not specified, a suitable default e.g. C<less> is chosen.


=item B<--view-result>

View output using a viewer.

This option will first save the output to a temporary file, then open a viewer
program to view the temporary file. If a viewer program is not chosen, a
suitable default, e.g. the browser, is chosen.


=back

=head2 Other options

=over

=item B<--help>, B<-h>, B<-?>

Display help message and exit.

=item B<--version>, B<-v>

Display program's version and exit.

=back

=head1 COMPLETION

This script has shell tab completion capability with support for several
shells.

=head2 bash

To activate bash completion for this script, put:

 complete -C csv2paras csv2paras

in your bash startup (e.g. F<~/.bashrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is recommended, however, that you install modules using L<cpanm-shcompgen>
which can activate shell completion for scripts immediately.

=head2 tcsh

To activate tcsh completion for this script, put:

 complete csv2paras 'p/*/`csv2paras`/'

in your tcsh startup (e.g. F<~/.tcshrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is also recommended to install L<shcompgen> (see above).

=head2 other shells

For fish and zsh, install L<shcompgen> as described above.

=head1 EXAMPLES

=head2 Convert to paragraphs format, show fields alphabetically, do not fold, hide empty values

 % csv-sort-fields INPUT.csv | csv2paras --width=-1 --hide-empty-values
