With arguments, # it will preview just the specified files. # The configured file format of source code is: # $HOME/crystalfaeries.net/src/.2016-08-26.fae.txt # 1st Line: "Date: 2016-08-26 10:00:00+00:00" # 2nd Line: optional "Expiry: 1500135412" # next Line: empty # remaining lines: simple HTML code # The output is normally directed to $HOME/crystalfaeries.net/fae/ # We shall preview into an alternate directory $HOME/crystalfaeries.net/fay/ # thus producing the file $HOME/crystalfaeries.net/fay/2016_08_26_fae.html # TYPICAL USAGE: # 1. When editing a file in the vi editor, when you :w # write the file out to disk, the editor displays the file name... # double click on that to get the full path into the clipboard... # :!preview # generates the HTML preview of that just edited file in $HOME/crystalfaeries.net/fay/ # for viewing with your browser. # 2. One of the ways to get into the vi editor with desired file is: # today YYYY-MM-DD (e.g. today 2020-04-05), and # quitting the edit session auto-previews what you were editing. # 3. When the blog script runs it invokes preview sans arguments, thereby # generates previews for all future articles in $HOME/crystalfaeries.net/fay/ let help=30 #line number within file - 1 rm $HOME/crystalfaeries.net/fay/{.??,}* 2>/dev/null # cleanup from previous execution(s) if [ $# -eq 0 ] then # we were invoked with NO arguments, therefore default to all pending future articles if [ "$(find $HOME/crystalfaeries.net/src/.2[0-9][0-9][0-9]-* -type f \! -name '*.swp' 2>/dev/null)" == "" ] then exit $? else exec $0 $(find $HOME/crystalfaeries.net/src/.2[0-9][0-9][0-9]-* -type f \! -name '*.swp' 2>/dev/null) # Y3K bug :-) exit -1 # how did you get here from the above exec? fi fi while [ $# -ne 0 ] do # we have another argument on command line to process: case "${1}" in --version | -v ) head -n 4 $0 | tail -n 1 exit $? ;; --help | -h ) head -n $help $0 exit $? ;; *) infile="$(basename ${1})"; shift # RELATIVE INfile #echo "INFILE: $infile" # DEBUG inpath="$HOME/crystalfaeries.net/src/${infile}" # ABSOLUTE INpath #echo "INPATH: $inpath" # DEBUG outfile="$(echo ${infile} | sed 's/^\.//;s/-/_/g;s/\./_/g;s/_txt$/.html/')" # RELATIVE OUTfile #echo "OUTFILE: $outfile" # DEBUG outpath="$HOME/crystalfaeries.net/fay/${outfile}" # ABSOLUTE OUTpath #echo "OUTPATH: $outpath" # DEBUG outurl="http://crystalfaeries.net/fay/${outfile}" # Preview URL #echo "OUTURL: $outurl" # DEBUG echo '' >> ${outpath} head -n 1 ${inpath} | sed 's/Date://;s/ *//;s/ *//;s/ .*$//' >> ${outpath} echo '' >> ${outpath} echo '' >> ${outpath} echo '' >> ${outpath} echo '
