MARKDOWN

 The markdown system uses a minimalist structured text format to produce
 html. 'markdown' is both a 'text format' and also a perl script used to
 turn that format into html. Using pandoc it is possible to convert
 markdown formatted text into other formats, such as pdf. Markdown may fill
 a gap between enscript and latex, where the user wants more control over
 how the produced document looks than can be obtained with 'enscript', but
 doesnt wish to become mired down in the complexities of 'latex'

CONVERTING TO HTML ....

 The 'markdown' perl script can only create html but 'pandoc' can produce
 other formats from the same markdown source text document. Markdown
 only seems to produce a 'fragment' of html (without head and body tags)

 * display a text document converted to html with markdown
 >> markdown document.txt | less

 * convert a document to html and save as 'doc.html'
 >> markdown doc.txt > doc.html

 * convert a document and add html and body tags to make a complete page
 >> (echo '<html><body>';markdown doc.txt;echo '</body></html>') > out.html
 >> markdown doc.txt|sed '1s/\\^/<html><body>/;\\$s.\\$.</body></html>.' > out.html
 >> pandoc -s -o out.html doc.txt \\#\\#(the same but better, using pandoc)

MARKDOWN SYNTAX ....

 The great advantage of markdown syntax is that the source document can be kept
 'clean' without distracting or ugly markup codes. Normal html can be inserted
 anywhere in a markdown document. If there is anything which markdown
 cannot do (such as tables) just use html tags instead.

DOCUMENT HEADINGS ....
 
 * create a 1st-level document heading (underline the text with '=' equals)
 --------------------------------------------------------------------------
 The Heading

\title{=========} 
\author{bumble.sourceforge.net} 
\maketitle 
\tableofcontents
 ,,,

 * create a markdown 2nd-level document heading
 ----------------------------------------------
 A Second Level Heading
 ----------------------
 ,,,

 * markup a 3rd level document heading 'Stone Fruit'
 >> \\#\\#\\# Stone Fruit

 * create a vim command ',ll' which underlines the current line with '-' dashes
 >> map ,ll yyp:s/[ ]*\\$// \\$\\backslash\\$| s/[ ]*\\$// \\$\\backslash\\$| s/[\\^ ]/-/g \\$\\backslash\\$| s/- \texttt{/--/g<cr>o}
 \\#\\#(place in 'vimrc'. This mapping helps to write markdown 2nd level headings)

 * create a vim command ',LL' which creates a markdown 1st level heading
 >> map ,ll yyp:s/[ ]*\\$// \\$\\backslash\\$| s/[ ]*\\$// \\$\\backslash\\$| s/[\\^ ]/=/g \\$\\backslash\\$| s/= \texttt{/==/g<cr>o}
 \\#\\#(This mapping command underlines the current line with '=' equals)

 * create a 'blockquote', that is text more indented than surrounding paragraphs
 >> > \\#\\#(blockquotes can contain headings and paragraphs

TEXT EMPHASIS ....

 * make a word or phrase emphasised
 >> the following is *emphasised text*
 >> the following is \\_emphasised text\\_ \\#\\#(more or less the same)

 * strongly emphasise words or phrases
 >> the following is **strongly emphasised text**
 >> the following is \\_\\_strongly emphasised text\\_\\_

LISTS ....

 The list marker can also be a '+' or a '*'. There is no difference
 between these types of lists

 * create an unordered (bulleted) list
 -------------------------------------
 - first item
 - second item
 - third and last
 ,,,

 * create an nested unordered list
 -------------------------------------
 - first item
 * sublist item 1

 * create an ordered list with a nested unordered list
 -----------------------------------------------------
 1. First
 2. Second:
 - Fee
 - Fie
 - Foe
 3. Third
 ,,,

 * create an unordered list with links to other parts of the page
 ----------------------------------------------------------------
 - [Chapter One](\\#chap1) 
 - [Chapter Two](\\#chap2) 
 - [Chapter Three](\\#chap3) 
 <h2 id='chap1'>...</h2>
 <h2 id='chap2'>...</h2>
 ,,,
 \\#\\#(notice how normal html is used to create the anchors)

 * create an ordered list
 ------------------------
 1. first
 2. second
 3. third
 ,,,

LINKS ....

 * create link in a document with the display text 'example link'
 >> This is an [example link](http://example.com/)
 \\#\\#(the html: this is an <a href="http://example.com/">example link</a>.</p>)

 * create link with a display text and also a 'title' (when the mouse hovers over)
 >> [example link](http://example.com/ "With a Title")

 * for pdf output the embedded code backtick may look best
 >> `http://google.com` \\#\\#(displays the link in fixed pitch font in pdf)

 * create and use a named link with display text 'Google'
 --------------------------------------------------------
 a search engine is [Google][1]
 [1]: \url{http://www.google.com} "Google"
 [2]: \url{http://www.yahoo.com} "Yahoo"

 * create a reference link with a space in the name
 --------------------------------------------------
 I start my morning with a cup of coffee and
 [The New York Times][NY Times].

 [ny times]: \url{http://www.nytimes.com/}
 ,,,

IMAGES ....

 * embedd an image file in the document, with an optional title
 ![a tree](/path/to/img.jpg "Title") \\#\\#(if the image is not found show 'tree')

 * embedd an image in the document using the 'reference' style syntax 
 --------------------------------------------------------------------
 ![alt text][id]

 [id]: \texttt{/path/to/img.jpg} "Title"
 ,,,

EMBEDDED CODE ....

 * use backticks '`' to show code with special characters in it
 >> dont use the `<blink>` tag

 * another example
 >> html entities can be named `\\&mdash;` or numbered `\\&\\#8212;`.

 * use 4 spaces or 1 tab of indentation to display a paragraph of code

 * use a backslash to escape special characters
 >> \\$\\backslash\\$* \\#\\#(this prints an asterix)

 * create a horizontal rule using 3 or more dashes, asterixes etc
 >> ---
 >> * * * \\#\\#(the same) 

GOTCHAS ....

 The table dashes must begin in the 5th column all later for the 
 table to be formatted correctly.
 
PANDOC MARKDOWN SYNTAX ....

 Pandoc allows a number of extensions to markdown syntax to allow
 for structures such as tables. These extensions can be turned off
 with the '--strict' switch

PANDOC

 pandoc extends both the syntax of markdown (allowing tables for example) and
 also the number of formats to which markdown can be output, including most
 importantly 'pdf'. Pandoc can perform other nice tricks such as putting
 automatic tables of contents into documents based on the section headings.

 Pandoc appears to be in active development (early 2010). Features such
 as 'tables' are only available in later versions of pandoc. And these
 versions are not available as debian packages.

INSTALLING PANDOC ....

 * install ghc6 which is a haskell compiler.

 * install the latest pandoc using the haskell 'cabal' tool
 >> cabal install pandoc

BASIC USAGE ....

 * convert a 'markdown' text document to html format with pandoc
 >> pandoc doc.txt
 >> pandoc -o out.html doc.txt \\#\\#(the same, html is the default)
 >> pandoc doc.txt -o out.html \\#\\#(better?)
 >> pandoc -f markdown doc.txt -o out.html \\#\\#(the same, but unnecessary)

 * show what header is added to a latex output file
 >> pandoc -D latex
 
 * convert multiple markdown files and a references file to an html page
 >> pandoc -s ch1.txt ch2.txt refs.txt > book.html

CONVERTING DOCUMENTS .... 

 If an output or input format is not given then pandoc will guess
 based on the file-names supplied.

HALIBUT

 @@ \url{http://www.chiark.greenend.org.uk/\\$\\verb|~|sgtatham/halibut/}

 Halibut is a system for creating formatted documents in a variety of
 output formats such as html (web-pages) pdf (printable) ... Halibut, uses
 a terse plain text input format. Halibut does not fully support unicode.
 Halibut may fill a gap between 'enscript' and 'latex' or 'docbook' in that
 the user may quickly produce a typeset document with 'formatting'. An
 alternative may be to write a new 'style' for enscript.

 Halibut produces nice pdf output, with automatic table of contents and
 cross-references. It is essentially a 'poor-mans' (and terse) latex

 * enscript seems to support the halibut format.

ENSCRIPT

 enscript is the simplest solution for creating a printed document,
 and such a handy way to quickly get some printed output without 
 wasting precious paper. its great. Enscript may be able to produce
 postscript and pdf output quickly but it also has many options, 
 which may make more complex typesetting tools unnecessary.

 * view a postscript file
 >> gv file.ps
 >> evince file.ps \\#\\#(nicer than the ancient 'gv')

BASIC USAGE ....

 The output file, if it exists, is overwritten.

 * convert plain text 'file.txt' to a pdf file 'output.pdf'
 >> enscript -p file.ps file.txt; ps2pdf file.ps

 * create a pdf file from 'file.txt'
 >> enscript -o - file.txt | ps2pdf - file.pdf 

 * create a postscript document from the '.txt' files in the current folder
 >> enscript -p output.ps *.txt

 * create a postscript document from 2 files, each line containing 'honey' 
 >> cat file1.txt file2.txt | grep -v honey | enscript -p output.ps
 \\#\\#(using this method enscript cant put the filename in the header)

HEADERS AND FOOTERS ....

 The header is what is printed at the top of each page of the 
 outputted postscript document.

 * create a pdf file with no "headers" called "output.pdf"
 >> enscript -B -p output.ps file.txt; pd2pdf output.ps
 >> enscript -Bp output.ps file.txt; pd2pdf output.ps \\#\\#(the same)
 >> enscript -Bo - file.txt | pd2pdf - output.ps \\#\\#(the same)

 * create a document with the text 'A summers day' at the top of each page 
 >> enscript -b 'The summers day' -p out.ps file.txt
 >> enscript --header='The summers day' -p out.ps file.txt \\#\\#(the same)

 * output a document with header as filename, current date, and page numbers
 >> enscript --header='\\$n \\%W Page \\$\\% of \\$=' -p out.ps file.txt
 >> enscript -b '\\$n \\%W Page \\$\\% of \\$=' -p out.ps file.txt

 \\#\\#(this would print 'out.ps 12/12/2003 Page 2 of 20' or something like that)
 
 * create a document with a header with 'justified' fields (left, center, right)
 >> enscript --header='\\$n|\\%W|Page \\$\\% of \\$=' -p out.ps file

 * create a postscript file 'output.ps' with fancy grey headers
 >> enscript -G -p output.ps list.txt
 \\#\\#(the header contains the date, file name and the page number)

 * create a ps document with a footer which is like 'Page 2 of 24'
 >> enscript --footer='Page \\$\\% of \\$=' -p out.ps file.txt

CHANGING THE FONT ....

 The text after the '-f' switch has to be a valid font specification,

 * show all valid font names which can be used with the enscript -f option
 >> less \texttt{/usr/share/enscript/afm/font.map} \\#\\#(your mileage may vary)
 >> find / -name 'font.map' \\#\\#(if the above didnt work)

 * create a postscript file "new.ps" using the font "Helvetica12"
 >> enscript -f "Helvetica12" -p new.ps file.txt 
 >> enscript -f "Helvetica@12" -p new.ps file.txt \\#\\#(the same)
 >> enscript -fHelvetica12 -p new.ps file.txt \\#\\#(this seems to work as well)

 * these font names are case sensitive!!
 >> enscript -f "helvetica12" -p new.ps file.txt 

 * create a postscript document using 8.5 point Times-Roman font
 >> enscript -f 'Times-Roman8.5' -p new.ps file.txt 
 >> enscript -f 'Times-Roman@8.5' -p new.ps file.txt \\#\\#(should be the same)

 * create a document using a font which is 10 points wide and 14 points high
 >> enscript -f 'Courier@10/14' -p new.ps file.txt 

 * create a postscript file with a smaller font
 >> enscript -f "Helvetica8" -p new.ps file.txt 
 >> enscript -f "Helvetica6" -p new.ps file.txt \\#\\#(only 6 points!)
 >> enscript -f "Helvetica4" -p new.ps file.txt \\#\\#(tiny, need a good printer)

CREATING BANNER TEXT WITH ENSCRIPT ....

 @@ \url{http://www.linux.com/archive/articles/55835}
 how to make 'web banners' (an image to go at the top of a webpage)
 using enscript, by Michael Stutz, the same guy who wrote the 
 Linux Cookbook for No Starch Press.

 * make a large image of the text 'Green Tree'
 >> echo "Green Tree" | enscript -B -f "Palatino-Bold48" -o blog.ps
 >> echo "Green Tree" | enscript -Bf "Palatino-Bold48" -p blog.ps \\#\\#(same)

 * do the whole thing in imagemagick
 >> convert -font Helvetica-Bold -pointsize 48 -background black -fill red label:'Hallo world' allo.png

 * crop out all the unnecessary space around the text and convert to 'jpg'
 >> convert -crop WxH+0+0 filename.ps filename.jpg \\#\\#(width and height)
 >> convert -trim +repage filename.ps filename.jpg \\#\\#(untested)

 * all in one go
 >> echo "Headlines for `date +'\\%B \\%e'`" | enscript -o - -B -f "Times-Bold48" | convert -crop 200x600+0+0 - headlines.png \\#\\#(untested)

MULTIPLE COLUMNS ....

 * change the horizontal column height
 >> --h-column-height=height

 * make a postscript file (from 2 text files) with 3 columns, and view it. 
 >> cat file1.txt file2.txt | enscript -3p output.ps; evince output.ps 
 
 * create a 2 column postscript file with lines separating columns and a frame 
 >> enscript -2 -j -p file.ps file.txt 
 >> enscript -2jp file.ps file.txt \\#\\#(the same, but better)

 * create a pdf document with 20 columns and no 'headers' (thats right, 20)
 >> enscript --columns=20 -2Bp file.ps file.txt; ps2pdf file.ps
 \\#\\#(the 'header' is the text which appears at the top of each page)

 * create a postscript document 'new.ps' with 9 columns from 'file.txt'
 >> enscript -9p new.ps file.txt

LANDSCAPE PRINTING ....

 * convert "file.txt" to pdf "file.pdf" landscape format with 2 columns
 >> enscript -2r -p file.ps file.txt; ps2pdf file.ps

CHANGING THE MARGINS ....

 * set the margins in the document to those specified
 >> enscript --margins=50:50:50:100 -p tree.ps tree.txt

 * In my version of enscript 1.6.4 the format for the margin command is 
 >> --margins=top:bottom:right:left which is a very unusual order

 * but in the documentation the format is stated to be
 >> --margins=top:bottom:right:left which would be more logical 

 * set the left and right margins to 50 pnts with top and bottom default
 >> enscript --margins=50:50 -p tree.ps tree.txt

 * indent every line by 2 character widths
 >> enscript -i 2l \\#\\#(2 character widths)
 >> enscript -i 20p \\#\\#(indent by 20 points)
 >> enscript -i 3i \\#\\#(3 inches)
 >> enscript -i 3c \\#\\#(3 centimetres)

UNDERLAYED TEXT ....
 
 Enscript can print an 'underlayed' text which is like a watermark
 which goes underneath the text from the file.

 * create a postscript file with a "watermark" large font text diagonally 
 * down the page.
 >> enscript -u"Resume" -p file.ps file.txt

OUTPUT FORMATS ....

 Instead of creating postscript files, enscript can also create 'rtf'
 (rich text format) files (which can be opened in Microsoft Word, for
 example) and 'html' files, which can be viewed with a web-browser such
 as 'google chrome', 'firefox' or 'internet explorer'.

 * create a rich text file 'output.rtf' from a text file with no headers
 >> enscript -wrtf -B -p output.rtf file.txt
 \\#\\#(rtf files can be opened in wysiwyg editors like MS Word)

 * create a colourised webpage of the file "tree.txt" 
 >> enscript -whtml --color -E -p file.html tree.txt 

CHANGING THE PRINTOUT ....

 * make a pdf file 'output.pdf' with each line preceded by the line number
 >> enscript --line-numbers -p output.ps list.txt; ps2pdf output.ps
 >> enscript -Cp output.ps list.txt; ps2pdf output.ps \\#\\#(the same)

 * create a document with each line numbered starting at line 20 
 >> enscript -C20 -p output.ps list.txt

THE PAGE SIZE ....

 * show what page sizes enscript can output to
 >> enscript --list-media

 * create a postscript document with an 'A5' page size
 >> enscript -M A5 -p out.ps file.txt
 >> enscript --media=A5 -p out.ps file.txt \\#\\#(the same)

MAKING BOOKLETS ....

 By using the 'N-up' printing facilities of enscript it should be possible
 to create 'booklets', that is, postscript documents which when printed out
 and folded in half, have all the pages in the right place (just like a
 real book; this is also called 'quires'). N-up printing involves putting
 a multiple of 2 logical pages on each physical page.

 * put 2 logical pages on each physical page
 >> enscript -U2 -p out.ps file.txt
 >> enscript -nup=2 -p out.ps file.txt \\#\\#(the same)

 * put 4 logical pages on each page
 >> enscript -U4 -p out.ps file.txt

 * other nup options which may do what we need
 -------------------
 --nup-columnwise
 Change the layout of the sub-pages in the N-up printing from row-
 wise to columnwise.
 --nup-xpad=num
 Set the page x-padding of the n-up printing to num PostScript
 points. The default is 10 points.
 --nup-ypad=num
 Set the page y-padding of the n-up printing to num PostScript
 points. The default is 10 points.
 ,,,

PRINTING CODE ....

 Enscript can be used to provide nice listing of software 'code'.

 * show what code languages enscript can pretty-print
 >> enscript --help-highlight | grep 'Name:' | less
 >> enscript --help-highlight | less \\#\\#(show more detailed information)

 * create a colourised webpage of the file "Point.java" with syntax highlighting
 >> enscript -whtml --color -E -p file.html Point.java

 * print a gaudy header, two columns, landscape, code highlighting, 2-up printing.
 >> enscript -G2rE -U2 foo.c

 * when a line is too long and must be wrapped print an arrow at the line end
 >> enscript --mark-wrapped-lines=arrow -p output.ps list.txt

 >> --mark-wrapped-lines=\{plus|box|arrow\}


OTHER PLAIN TEXT DOCUMENTATION SYSTEMS

 This book tries to elucidate the forest of different ways and formats in
 which to write text documentation and the software which is used to transform
 the text into other digital formats and printed documents.

MAN PAGES
-----------------------------------------------------------

 man: software <man>ual pages

 Man ('manual') pages is the traditional Unix documentation format.
 The man page format is a simple plain text format using macros for
 the troff or groff document system. The Man documentation system is 
 specifically designed for documenting software.

 links to documents by Kernighan ...
 @@ \url{http://babbage.cs.qc.edu/courses/cs701/Handouts/man\\_pages.html} 

VIEWING MAN PAGES ....

 * viewing a man page with 'man' (the normal way to view a man page)
 >> man program \\#\\#(the file program.n must be in the manpath)

 * viewing the bobble manpage with groff (useful when writing a man page)
 >> groff -man -Tascii bobble.1 | less
 >> groff -man -Tutf8 bobble.1 | less

 * viewing the 'bobble' program man page with nroff
 >> nroff -man bobble.1 | less
 
 * view the raw groff text for the 'bobble' program man page.
 >> zless .../man/man1/bobble.1.gz \\#\\#(if the pages are compressed)
 >> less .../man/man1/bobble.1 \\#\\#(if the pages are not compressed) 
 \\#\\#(useful to learn how to write a man page.)
 \\#\\#(type 'manpath' to find the path to the manpages)

 * other viewing tools are xman, tkman, info

WRITING MAN PAGES ....

 * see the conventions for writing a man page
 >> man 7 man

 * see the formatting codes available
 >> man groff\\_man

 \begin{enumerate}
  \item 
 \item decide what section the page should go in (see:man page sections)
 \item write the man page
 \item name the file 'name.n' where 'n' is the section
 \item place the file in .../man/manN/ where 'N' is the section (same as above)
 \item if the page is not written in english, place the file
 in the folder .../man/aa/manN/ where 'aa' is a language or locale code,
 for example 'fr' for french, or 'es' for spanish. and 'N' is the 
 section.
 \item
\end{enumerate}
  
MAN FORMATTING CONVENTIONS ....

 While the author of a unix man page is free to format the document as
 she feels fit, certain conventions are time-tested and true.

 * In the synopsis section use bold alternating with italic for functions
 >> .BI "myfunction(int " argc ", char **" argv );

 * file names in italic outside of the 'synopsis' section
 >> .I \texttt{/usr/include/stdio.h}

 * in the synopsis section, make file names bold
 >> .B \\#include <stdio.h>

 * put references to other man pages in bold alternating with roman
 >> .BR man (7)

 * format acronymns in a small font
 >> .SM UNIX

 * summarize command options with .IP
 >> .IP -b

MAN FORMATTING CODES ....

 * view the man macro help for a list of formatting codes
 >> man groff\\_man \\#\\#(as usual, this contains no examples)

 * create a document title
 >> .TH FOO 1 "MARCH 2003" Linux "User Manuals"
 \\#\\#(command name: foo, section: 1 (user commands) )
 \\#\\#(last revision: march 2003, other title: Linux ...)

 * section heading
 >> .SH heading

 * subsection headings
 >> .SS heading

 * display a sentence in italics 
 >> .I "some words" 

 * put the word 'type' in italics
 >> \texttt{/fItype/fP} \\#\\#(groff codes)

 * insert preformatted text in a man page (using groff requests)
 ---------------------------------------------------------------
 .nf
 pre formatted text ...
 .fi
 ,,, 
 
 * begin a new paragraph
 >> .PP

 * indent an option list with .TP (the first line after .TP is the label)
 >>> 
 .TP
 \\$\\backslash\\$-h
 display a short help text
 .TP
 \\$\\backslash\\$-d
 use the given device 
 <<<
 \\#\\#(.TP has the advantage over .IP that the paragraph label can be formatted)

 * hanging left indented paragraph
 >> .HP 

 * indented paragraph with label
 >> .IP label

 this can be used for summarizing options etc. If the label is long
 then the indented paragraph is begun on a new line (definition list
 style) other wise the indented paragraph is begun on the same line.
 (table style)

 example: 
 .IP -b
 turn on debug mode 
 .IP "-config file"
 load the specifed config file
 --;

 * indent the following text by the default amount 
 >> .RS 

 * indent the following text by 10 
 >> .RS 10

 * stop indenting text
 >> .RE stop indenting
