[Tex/LaTex] Remove space between chapter breaks in List of Figures and List of Tables

front-matterspacingtable of contents

Am fightning for space in my thesis 😉

Have already been able to remove vertical space between chapter breaks in TOC, but trying to do the same thing with LoF and LoT

At present I am using the tocloft package. Using many of the custom spacings in that package I managed to play around with the TOC to my liking

However am not having the same success with the LoF and LoT. Found a bunch of solutions on this stack exchange that worked for other people but so far haven't worked for me.

Here's the preamble that I am using right now:
(note there are a couple things commented out, because I thought they did nothing when I had the commands) 

\documentclass[10pt, letterpaper, oneside]{book}

\renewcommand{\baselinestretch}{1.5}

Best Answer

If you would use the memoir (covers the book class) class instead of book then the answer is simple. In the preamble put:

\renewcommand{\insertchapterspace}{}

which revises the \chapter macro to put no additional spaces into the LOF and ToC.

In your MWE you have a line along the lines of

\patchcmd{\@chapter}{\addtocontents{lof}{\protect\addvspace{10\p@}}}{}{}{}

Why do you have two copies of this?

Perhaps if you changed this to ...\addvspace{0\p@}... like

\patchcmd{\@chapter}{\addtocontents{lof}{\protect\addvspace{0\p@}}}{}{}{}

you would get what you want in the LoF.

For the ToC a similar macro, replacing {lof} by {lot}.
