[Editor Plugin] Editor Chains - Page 2

How do I save after all actions are done? It seems there is no "save" action and I have to save it manually by clicking the button. Which also make it useless with Action Chain when I try to batch process multiple book from main GUI, nothing is saved.

Thanks.

Thanks.

When used with Actions Chains, it automatically saves all the changes. It also keeps a backup of the old file (there is a setting to turn this off).

Yes, I found that it does save when I run action chains.
But the issue I have now is that the result is different when I run Action Chains from when I run Editor Chains. Even though the only step in Action Chains is calling the exact chain in Editor Chains.

The chain is quite simple

- Conver to epub3
- embed fonts
- subset fonts
- fix HTML
- beautify all

If I run Editor chains, everything is executed as expected. After the chain I run "fix HTML/beautify" from menu and nothing will be changed.

But if I run Action Chains, fix HTML and beautify doesn't seem to work. Once it completes, I edit the book and run fix HTML/beautify from menu, there are still a lot changes.

The difference between what happens when in editor mode and what happens in Action Chains, is caused by the fact the calibre parses html differently when in editor mode. When in editor mode, calibre will remove some meta tags, that are otherwise not deleted. I don't know the exact reasons for why calibre does this, but I trust that Kovid has done this for good reasons.

It is trivial (in terms of code) to change the plugin to have it perform exactly the same in both modes. But I don't know if this would break some other action or functionality of the plugin. What is not trivial, however, is repeating all the hours of testing that has gone into the plugin to ensure nothing else breaks because of this change, which is not something I am prepared to do.

Anyway, The difference in output is not significant (some meta tags and whitespace) and does not affect the end result. The bottom line is that the html files are beautified and fixed in both modes. If you are bent on having them exactly the same, try the chain attached below, which deletes the culprit meta tags. If you are still not getting the result you want, there is nothing to be done as the changes required for this require huge amount of testing that I am not ready to do.

This is fantastic. I have created a reduce file size chain with subset embedded fonts, remove unused CSS, and compress pictures down to 50%.

From within the editor, it makes the changes, I save, and I can immediately see the reduction in filesize. When running from Action Chains, it runs and completes and does reduce the size as expected, but the change in filesize is not shown. Even closing and reopening Calibre does not show the change in size. I have to edit the book, add and remove a space to a single file and then save to see the results of the chain.

Fix: When running from Action Chains, notify calibre to update filesizes of modified files.

Thank you. Works perfectly!

Version 0.8.9

New Action "Run Command"

This action allows you to run a command on files inside the book. To better illustrate this I will give an example of chain I made which uses ImageMagick convert command to convert jpg and png pictures to a lower quality jpg and changes the colorspace to gray. The action will run this command for the selected files, and replace them with the resulting files. Below is a screenshot of the configuration for this action.

Notes:

You must have the commmand installed on your system.
Note the use of the placeholders: {inputfile}, {outputfile}.
If the resulting output files are of different extension the input files as in the example in the screenshot, you must specify the output extension so that it is appended to the {outputfile}. Also the original filenames inside the book will changed to reflect the new extension.
The configuration gives you the option to specify what files to include or exclude. Note that I included all png and jpg images except those that contain the name cover.
Using the combination of Action Chains and Editor Chains, you can run this action on multiple books. Refer to the first post of this thread for more on how to combine the two plugins.

!! Congratulations!!
For me it will be very useful.
But I have ImageMagick installed correctly (although my knowledge of its use is zero) on Windows 10.
I have copied your screenshot as it is and the thing does not work.
I'm guessing it has to do with {inputfile} and {outputfile}, and it would be great if you could tell me what to do.
Thanks in advance.

Unfortunately I cannot test on Windows. A quick search suggests that maybe the command on Windows should be:

Code:

magick convert path/to/input/image -quality 80 -colorspace gray /path/to/output/image

If the above command does not work on Windows, then the problem is not in the plugin and you have to figure the right command yourself.

If the command runs successfully on your machine, run it in Editor Chains and post the debug log. You can run the editor in debug mode using the following command:

Code:

calibre-debug --edit-book

jbacelar · 08-31-2023, 06:02 PM

Unfortunately it doesn't work with the new command either.
Attached (in case it is of any use) the debug log.
Thanks again for the try.

That's a problem with running the command on Windows. I suggest you open the Windows command line (cmd) and run this command on a test image:

Code:

magick convert path/to/input/image -quality 80 -colorspace gray /path/to/output/image

Take whatever error messages arising from the command to the ImageMagick forums to get help on what went wrong.

Once you get the command working on Windows command line (using cmd.exe), we would be able to investigate whatever problems arises with the plugin.

jbacelar · 09-01-2023, 03:37 AM

Code:

C:\Users\JB>magick convert path/to/input/wizard.jpg -quality 80 -colorspace gray /path/to/output/wizard.jpg
convert: unable to open image 'path/to/input/wizard.jpg': No such file or directory @ error/blob.c/OpenBlob/3569.
convert: no images defined `/path/to/output/wizard.jpg' @ error/convert.c/ConvertImageCommand/3354.

Instead with this one:

Code:

C:\Users\JB>magick convert wizard.jpg -quality 80 -colorspace gray wizard.jpg

It has worked perfectly.

capink · 09-01-2023, 12:13 PM

both /path/to/input and /path/to/output are meant to be replaced with actual paths on your system. If you are doing this and the command is still producing errors, this would be some trouble with ImageMagick on Windows that I wouldn't be be to assist much with. Your best bet, as I said, would be the ImageMagick forums, because for the plugin to work with command, it must accept the full paths.

I'm getting the same issue too (Windows 11).

I have tried running clean-css cli with both directly and with a bat script I made that takes a css file as an input, and neither do anything.

My error log shows the same thing, "Command error: Return code is 1 when running command for file: {insert file name here}"
