From 58697ebe785b1f7eb4713d8874cd5aaae4d6a03b Mon Sep 17 00:00:00 2001 From: fiddlosopher Date: Mon, 8 Jan 2007 19:55:34 +0000 Subject: Modified shell scripts to use new Pandoc --dump-args and --ignore-args features. This allows a simpler, cleaner design. Make use of TEXINPUTS environment variable to ensure that pdflatex will find images and other sources in the working directory from which markdown2pdf is called. git-svn-id: https://pandoc.googlecode.com/svn/trunk@456 788f1e2b-df1e-0410-8736-df70ead52e1b --- src/wrappers/common.sh | 16 ++++++++ src/wrappers/html2markdown.in | 90 ++++++++++++++++++------------------------- src/wrappers/markdown2pdf.in | 35 ++++++++--------- 3 files changed, 70 insertions(+), 71 deletions(-) diff --git a/src/wrappers/common.sh b/src/wrappers/common.sh index 2cde64157..9605f5940 100644 --- a/src/wrappers/common.sh +++ b/src/wrappers/common.sh @@ -6,6 +6,11 @@ NEWLINE=' err () { echo "$*" | fold -s -w ${COLUMNS:-110} >&2; } errn () { printf "$*" | fold -s -w ${COLUMNS:-110} >&2; } +usage () { + err "$1 - $2" # short description + err "See the $1(1) man page for usage." +} + # Portable which(1). pathfind () { oldifs="$IFS"; IFS=':' @@ -25,3 +30,14 @@ for p in pandoc $REQUIRED; do exit 1 } done + +CONF=$(pandoc --dump-args "$@" 2>&1) || { + errcode=$? + echo "$CONF" | sed -e '/^pandoc \[OPTIONS\] \[FILES\]/,$d' >&2 + [ $errcode -eq 2 ] && usage "$THIS" "$SYNOPSIS" + exit $errcode +} + +OUTPUT=$(echo "$CONF" | sed -ne '1p') +ARGS=$(echo "$CONF" | sed -e '1d') + diff --git a/src/wrappers/html2markdown.in b/src/wrappers/html2markdown.in index 740d69588..6d0256274 100644 --- a/src/wrappers/html2markdown.in +++ b/src/wrappers/html2markdown.in @@ -3,6 +3,7 @@ # uses an available program to fetch URL and tidy to normalize it first REQUIRED="tidy" +SYNOPSIS="converts HTML from a URL, file, or STDIN to markdown-formatted text." ### common.sh @@ -59,63 +60,46 @@ grab_url_with () { $prog "$@" "$url" } -add_option () { - options="$options$NEWLINE$1" -} - -options= argument= encoding= grabber= # Parse command-line arguments -while [ $# -gt 0 ]; do - case "$1" in - -h|--help) - pandoc -h 2>&1 | sed -e 's/pandoc/html2markdown/' \ - -e '/^[[:space:]]*\(-f\|-t\|-S\|-N\|-m\|-i\|-c\|-T\|-D\|-d\)/,/./d'\ - 1>&2 - err " -e ENCODING, --encoding=ENCODING" - err " Specify character encoding of input" - err " -g COMMAND, --grabber=COMMAND" - err " Specify command to be used to grab contents of URL" - exit 0 ;; - -v|--version) - pandoc -v 2>&1 | sed -e 's/pandoc/html2markdown/' 1>&2 - exit 0 ;; - -e) - shift - encoding=$1 ;; - --encoding=*) - wholeopt=$1 - # extract encoding from after = - encoding=${wholeopt#*=} ;; - -g) - shift - grabber=$1 ;; - --grabber=*) - wholeopt=$1 - # extract encoding from after = - grabber=${wholeopt#*=} ;; - -o|--output|-b|--tab-stop|-H|--include-in-header| \ - -A|--include-after-body|-C|-B|--include-before-body| \ - -C|--custom-header|-T|--title-prefix) - add_option $1 - shift - add_option $1 ;; - -*) add_option $1 ;; - *) - if [ -z "$argument" ]; then - argument=$1 - else - err "Warning: extra argument '$1' will be ignored." - fi ;; - esac - shift -done +parse_arguments () { + while [ $# -gt 0 ]; do + case "$1" in + --encoding=*) + wholeopt="$1" + # extract encoding from after = + encoding="${wholeopt#*=}" ;; + -e|--encoding|-encoding) + shift + encoding="$1" ;; + --grabber=*) + wholeopt="$1" + # extract encoding from after = + grabber="\"${wholeopt#*=}\"" ;; + -g|--grabber|-grabber) + shift + grabber="$1" ;; + *) + if [ -z "$argument" ]; then + argument="$1" + else + err "Warning: extra argument '$1' will be ignored." + fi ;; + esac + shift + done + export encoding + export grabber + export argument +} -# Unpack options.
