Under the lyx temp directory, content.lyx and its embedded files are usually
saved as
-$temp/file.lyx
-$temp/figure1.png for ./figure1.png)
-$temp/sub/figure2.png for ./sub/figure2.png)
+$temp/$embDirName/file.lyx
+$temp/$embDirName/figure1.png for ./figure1.png)
+$temp/$embDirName/sub/figure2.png for ./sub/figure2.png)
This works fine for embedded files that are in the current or deeper directory
of the document directory, but not for files such as ../figures/figure.png.
A unique name $upDirName is chosen to represent .. in such filenames so that
'up' directories can be stored 'down' the directory tree:
-$temp/$upDirName/figures/figure.png for ../figures/figure.png
-$temp/$upDirName/$upDirName/figure.png for ../../figure.png
+$temp/$embDirName/$upDirName/figures/figure.png for ../figures/figure.png
+$temp/$embDirName/$upDirName/$upDirName/figure.png for ../../figure.png
This name has to be fixed because it is used in lyx bundled .zip file.
-Note that absolute files are not embeddable because there is no easy
-way to put them under $temp.
+Using a similar trick, we use $absDirName for absolute path so that
+an absolute filename can be saved as
+
+$temp/$embDirName/$absDirName/a/absolute/path for /a/absolute/path
