Background
I use TiddlyWiki from NodeJs. Here is the official documentation
<https://tiddlywiki.com/#Installing%20TiddlyWiki%20on%20Node.js> on it. To
make offline copy, use the command
tiddlywiki mynewwiki --build index
It generates a file index.html in the output folder. When the command is
run again, the index.html is overwritten. I was interested in keeping the
backups intact, like so
index-2018-06-20-1131.html
index-2018-06-30-0040.html
index-2018-07-05-0037.html
index-2018-07-05-1839.html
index-2018-07-06-0154.html
This way, I can have a timeline of my TiddlyWiki backups, enabling me to
restore any particular backup.
Solution
I wrote following shell script.
1. It saves TiddlyWiki to file using build command
2. Appends timestamp to the filename
function tiddlysave
set p /Users/talha/Dropbox/TiddlyNotes/output/
set f index.html
set file "$p""$f"
tiddlywiki ~/Dropbox/TiddlyNotes --verbose --build index
if test -e "$file"
set_color -o red
echo "index.html found"
set append (stat -f "%Sm" -t "%F-%H%M" "$file")
set rootname (echo $f | sed 's/\.[^.]*$//')
set ext (echo $file | sed 's/.*\.//')
set new "$p""$rootname"-"$append"."$ext"
set_color -o yellow
echo "Rename $file → $new"
set_color normal
mv -v "$file" "$new"
endend
Now all I have to do, is to run tiddlysave command from any folder in the
system. I tend to run this command after making any significant change in
TiddlyWiki or trying any new plugin or macro.
I can also setup a cron job to take backups at regular intervals.
Limitations
It runs on Fish Shell <http://fishshell.com/> and macOS.
Modifying it for bash shouldn’t be difficult at all. Though on Linux, stat
command works differently. Instead of stat -f "%Sm" -t "%F-%H%M" $file you
can use
stat -c %y filename
# or
date -r filename
Why not rely on Dropbox Version support?
Dropbox automatically creates version of files. But with tiddlysave, I am
in control when to take backup.
Hope someone will find it helpful.
