txt2html/HTML::TextToHTML Sample Conversion

This sample is based hugely on the original sample.txt produced by Seth Golub for txt2html.

I used the following options to convert this document:

     -titlefirst -mailmode -make_tables
     --custom_heading_regexp '^ *--[\w\s]+-- *$'
     --system_link_dict txt2html.dict
     --append_body sample.foot --infile sample.txt --outfile sample.html

This has either been done at the command line with:

perl -MHTML::TextToHTML -e run_txt2html -- options

or using the script

txt2html options

or from a (test) perl script with:

        use HTML::TextToHTML;
        my $conv = new HTML::TextToHTML();

Good idea. I'll write something up.

The header lines were kept separate because they looked like mail headers and I have mailmode on. The same thing applies to Bozo's quoted text. Mailmode doesn't screw things up very often, but since most people are usually converting non-mail, it's off by default.

Paragraphs are handled ok. In fact, this one is here just to demonstrate that.

(Ok, it wasn't that important)


Since this is the first header noticed (all caps, underlined with an "="), it will be a level 1 header. It gets an anchor named "section_1".

Another example

This is the second type of header (not all caps, underlined with "="). It gets an anchor named "section_1_1".

Yet another example

This header was in the same style, so it was assigned the same header tag. Note the anchor names in the HTML. (You probably can't see them in your current document view.) Its anchor is named "section_1_2". Get the picture?

-- This is a custom header --

You can define your own custom header patterns if you know what your documents look like.

Features of HTML::TextToHTML

                 It just needs to have enough whitespace in the line.
        Surrounding blank lines aren't necessary.  If it sees enough
        whitespace in a line, it preformats it.  How much is enough?
        Set it yourself at command line if you want.

Example of short lines

We're the knights of the round table
We dance whene'er we're able
We do routines and chorus scenes
With footwork impeccable.
We dine well here in Camelot
We eat ham and jam and spam a lot.

Example of varied formatting

If I want to emphasize something, then I'd use stars to wrap around the words, even if there were more than one, that's what I'd do. But I could also underline words, so long as the darn thing was not a_variable_name, in which case I wouldn't want to lose the underscores in something which thought it was underlining. Though we might want to underline more than one word in a sentence. Especially if it is The Title Of A Book. For another kind of emphasis, let's go and put something in bold.

But it doesn't even need to be that simple. Something which is really exciting is coping with italics and similar things spread across multiple lines.

Example of Long Preformatting

(extract from Let It Rain by Kristen Hall)

        I have given, I have given and got none
        Still I'm driven by something I can't explain
        It's not a cross, it is a choice
        I cannot help but hear his voice
        I only wish that I could listen without shame

        Let it rain, let it rain, on me
        Let it rain, oh let it rain,
        Let it rain, on me

        I have been a witness to the perfect crime
        Wipe the grin off of my face to hide the pain
        It isn't worth the tears you cry
        To have a perfect alibi
        Now I'm beaten at the hands of my own game

        Let it rain, let it rain, on me
        Let it rain, oh let it rain,
        Let it rain, on me

Definition Lists

A definition list comprises the following:

The term part of a DL item is a word on a line by itself, ending with a colon.
The definition part of a DL item is at least one paragraph following the term.

If one has more than one paragraph in the definition, the first line of the next paragraph needs to be indented two spaces from where the term starts, otherwise we don't know that it belongs to the definition.

Examples of Tables


Here is a simple ALIGN table:

-eFile exists.
-zFile has zero size.
-sFile has nonzero size (returns size).

Here are some of the conditions of ALIGN tables:

Context:A table needs to be surrounded by blank lines.
Length:A table must contain at least two rows.
Width:A table must contain at least two columns.
Spacing:There needs to be at least two spaces between the columns,
otherwise there might be some random paragraph which
could have inter-word spacing that lined up by accident.
Cell Size:If you have more than one line (as just above) then
you will simply get empty cells where the other column is empty.
Alignment:Alignment of cells is attempted to be preserved.

This is a table with a border.


This is the same table like Postgresql would make it.


(4 rows)


A delimited table needs to have its delimiters at the start and end, just to be sure that this is a table.


And one can have almost any delimiter one wishes.

There are some things which this module doesn't handle yet which I would like to implement.

  1. I would like to be able to preserve lettered lists, that is:
    1. recognise that they are letters and not numbers (which it already does)
    2. display the correct OL properties with CSS so as to preserve that information.

The footer is everything from the end of this sentence to the </BODY> tag.
