+This file is README.txt from version 1.0 of the free and
+open-source LaTeX package "listparskip," released December 
+2024. The listparskip package changes the rules for vertical
+spacing before and after list environments. See the user
+guide for more information. See below for installation and
+license information.
+
+*********************************************************
+
+                     How to Install
+
+To install listparskip automatically, update your TeXLive or
+MacTeX distribution or use a package manager such as tlmgr.
+
+To install listparskip manually requires two steps as follows.
+
+Step 1: You will need to generate the package file
+listparskip.sty from listparskip_code.dtx. You can do this in
+two ways:
+
+  (1) Running Plain TeX on listparskip_code.dtx will create
+      listparskip.sty as well as several other tex files that
+      can be used for typesetting documentation.
+
+  (2) Running LaTeX on listparskip_code.dtx will produce the
+      files listed in point (1) including listparskip.sty as
+      well as listparskip_code.pdf, which documents the 
+      package code.
+
+Step 2: Once you have created listparskip.sty, you should
+move it into a directory searchable by TeX to complete the
+installation. If you are unsure how to do this, consult your
+TeX distribution.
+
+*********************************************************
+
+                  Installation Contents
+
+Besides this README, the installation contains the following
+files:
+
+  (1) listparskip_code.dtx: the main file. See above for
+      instructions to generate listparskip.sty from this
+      file and complete the installation.
+
+  (2) listparskip_code.pdf: documentation of the package
+      code.
+
+  (3) listparskip_user_guide.pdf: a user guide.
+
+  (4) listparskip_example.pdf: an example of listparskip. 
+
+Typesetting listparskip_code.dtx will create
+listparskip_user_guide.tex, which is the tex file that
+produces the user guide in point (3) above. It will also
+create listparskip_example.tex, which is the tex file
+that produces the example file in point (4) above.

+% \noindent This file documents the code for the \textsf{listparskip} package. It is not a user guide! If you are looking for discussion of how \textsf{listparskip} will change the layout of your documents, see |listparskip_user_guide.pdf| and |listparskip_example.pdf|, which are included with the \textsf{listparskip} installation and are available on \textsc{ctan}.
+% 
+% Spacing in list environments is subtle, and it will be helpful to summarize how \LaTeX\ implements vertical space in lists. Every list environment comes from either a |\list| or |\trivlist| macro, and |\list| is responsible for the standard list structure that shows up in enumerate, itemize, and description environments. A |\trivlist| is a list without any indentation or space for item markers, and this command comes up, for example, in quotations or some verbatim environments where fine control over vertical spacing is important. Both user-level commands serve as wrappers for the internal macro |\@trivlist|, which translates the definition of the current environment into internal list control sequences for processing later in the document. Default dimensions for different list levels come from the class file in the |\@listi| through |\@listiv| macros.
+% 
+% When the user enters a list environment, for example with |\begin{enumerate}|, \TeX\ will at some point encounter |\@trivlist|. When that happens, \TeX\ prepares to add |\topsep| and |\parskip| to the main vertical list, and if \TeX\ is in \v mode, it prepares to add an extra |\partopsep|. The environment call itself doesn't add space or penalties, and instead, the first |\item| inside the list environment is responsible for these changes. Future uses of |\item| add an |\itempenalty| and |\itemsep| to the main vertical list, and any |\parsep| space additions happen automatically because \LaTeX\ sets |\parskip| to |\parsep| inside |\list| immediately after |\@trivlist|. At the end of the list environment, \TeX\ adds |\topsep| and, if it was present at the beginning of the environment, |\partopsep| to the main vertical list. \LaTeX\ does not instruct \TeX\ to manually add |\parskip|, so if the user includes, for example, an |\hbox| right after |\end{enumerate}|, \TeX\ will not add |\parskip| there. (\TeX\ is always in \v mode after it begins or ends a list environment.)
+% 
+% Changing this behavior at the beginning of lists is straightforward---\textsf{listparskip} patches |\@trivlist| by treating the extra |\parskip| the same way \LaTeX\ normally treats |\partopsep|. Dealing with after-list space is more complicated. Normally |\@endparenv| adds |\topsep| and possibly |\partopsep| directly to the main vertical list, but we want a more tailored approach. Instead, \textsf{listparskip} redefines |\@endparenv| to add |\topsep| to the main vertical list and (globally) save |\topsep| plus |\partopsep| in |\@tempskipa|. Immediately outside the list environment, \textsf{listparskip} sets |\parskip| to 0pt and redefines |\par| to remove the previous |\topsep| and replace it with |\@tempskipa|. To ensure that (a) the extra |\partopsep| happens only if a blank line immediately follows the list and (b) \TeX\ avoids inserting |\parskip| only if \h mode material immediately follows the list, \textsf{listparskip} makes |\par|, |\everypar|, and |\item| restore |\par| and |\parskip| to their previous (local) definitions. Using creative groupings or manually redefining |\par| or |\everypar| right after a list may break things, so please be careful!
+% 
+% Sometimes the user will want to include non-horizontal material, such as a box, immediately after a list environment without worrying about an extra or missing |\parskip| or |\partopsep|. In the implementation outlined above, \textsf{listparskip} adds or removes this space whenever \TeX\ first encounters a |\par| or \h mode material after a list. A box is neither of these things, so any after-list adjustments will show up after the box instead of before. The easiest way to avoid this problem is to transition to \h mode and then back to \v mode before adding the box, and the macro |\nullline| does this.

+\toks@\expandafter\expandafter\expandafter
+  {\expandafter\patch@trivlist\@trivlist\@nil}
+\edef\@trivlist{\the\toks@}
+%    \end{macrocode}
+% We change |\@endparenv| so that it adds only |\topsep|. We set |\@tempskipa| globally in order to access its value in |\@doendpe|, which is outside the current group.
+%    \begin{macrocode}
+\def\@endparenv{%
+  \addpenalty\@endparpenalty
+  \addvspace\topsep
+  \global\@tempskipa\glueexpr\topsep+\partopsep\relax
+  \@endpetrue}
+%    \end{macrocode}
+% Normally |\@restoreparskip| is |\relax|, but we change it in |\@doendpe| to return |\parskip| back to its previous value, which we have stored in |\@saveparskip|. This makes |\parskip\z@| a one-op. (Or a no-op if \TeX\ sees a |\par| or |\item| after the list and doesn't enter \h mode.)\vadjust{\penalty-100}
+%    \begin{macrocode}
+\let\@restoreparskip\relax
+\def\@doendpe{%

+  \parskip\z@
+  \def\@restoreparskip{%
+    \parskip\@saveparskip
+    \let\@restoreparskip\relax}
+%    \end{macrocode}
+% We add |\@restoreparskip| to |\par|, and the |\addvspace| will replace the previous addition of |\topsep| from |\@endparenv| with |\topsep| plus |\partopsep|. We put everything inside an |\edef| so we can expand |\the\@tempskipa| now and not worry about a redefinition of |\@tempskipa| before the next |\par|. (Unlikely, but you never know.)
+%    \begin{macrocode}
+  \edef\par{%
+    \unexpanded{\clubpenalty\@clubpenalty
+      \everypar{}%
+      \@restorepar\par
+      \@restoreparskip
+      \@endpefalse}%
+    \noexpand\addvspace{\the\@tempskipa}}%
+%    \end{macrocode}
+% The contents of |\everypar| here are the same as the \LaTeX\ default in this situation except that we add |\@restorepar| and |\@restoreparskip|.
+%    \begin{macrocode}
+  \everypar{\@restorepar
+    \@restoreparskip
+    {\setbox\z@\lastbox}%
+    \everypar{}%
+    \@endpefalse}}
+%    \end{macrocode}
+% Next we add |\@restorepar| to the beginning of |\item|. Calling |\patch@item| on a control sequence |#1| will insert |\@restorepar| and |\@restoreparskip| into |#1|'s definition.
+%    \begin{macrocode}
+\def\patch@item#1{%
+  \edef#1{\noexpand\@restorepar
+    \noexpand\@restoreparskip
+    \expandafter\unexpanded\expandafter{#1}}}
+%    \end{macrocode}
+% The \textsf{hyperref} package sometimes turns |\item| into a wrapper for itself. In that case, \textsf{hyperref} will have renamed |\item| to |\H@item|, so we patch that instead.
+%    \begin{macrocode}
+\@ifpackageloaded{hyperref}{%

+    \patch@item\H@item
+  \else
+    \patch@item\item
+  \fi}{\patch@item\item}
+%    \end{macrocode}
+% Finally, create the command that forces a transition from \textsc v mode to \h mode and back without (directly) adding any space.

+\noindent Most \LaTeX\ users are familiar with the enumerate and itemize environments, and a number of other environments share the same underlying macros and structure. These list environments are useful and versatile, and they come up in many different situations where fine control over vertical spacing is important.\footnote{There is an overlap in terminology. The list environments described in this document are very different from horizontal and vertical lists in the \TeX\ language.} The dimensions |\topsep|, |\parsep|, |\partopsep|, and |\itemsep| control vertical spacing for list environments, and by default, \LaTeX\ determines the space immediately outside a list as follows:
+\begin{itemize}
+\item Always add |\topsep| before and after a list
+\item Add |\parskip| (not |\parsep|) always before a list and usually after it\footnote{\TeX\ treats any text after a list as the start of a new paragraph, so if the next material to be typeset is text, \TeX\ adds \vrb\parskip\ after the list. If the user includes a box or rule instead of text, it does not trigger the start of a paragraph, and \TeX\ does not add \vrb\parskip.}
+\item If a list begins outside of a paragraph, add |\partopsep| before and after the list
+\end{itemize}
+If |\parskip| is nonzero, for example in a formal letter, it is impossible to include a list inside a paragraph without the inter-paragraph space suggesting that the list forms its own paragraph. (Unless the user manually changes |\parskip| or adds negative vertical glue.) Similarly, \LaTeX\ chooses whether to add |\partopsep| after a list independently of what happens at that point in the source code.
+
+The \textsf{listparskip} package modifies this behavior by making the |\parskip| and |\partopsep| spacing depend more closely on paragraph structure from the source code. Under \textsf{listparskip} rules, the space around lists happens as follows:
+\begin{itemize}
+\item Always add |\topsep| before and after a list
+\item If a list begins outside of a paragraph, add |\parskip| and |\partopsep| before the list
+\item If a blank line comes immediately after the list in the source code, always add |\partopsep| and usually add |\parskip|
+\end{itemize}
+These changes happen automatically after loading the package, and they allow the user to control whether \TeX\ positions a list environment as its own paragraph or as part of the surrounding paragraph. When |\parskip| and |\partopsep| are both 0pt, this package does nothing, but for an example of what can happen when either dimension is positive, see |listparskip_example.pdf|, which is included with the \textsf{listparskip} installation and is available on \textsc{ctan}. Users can load \textsf{listparskip} with the standard |\usepackage{listparskip}| syntax, and the package has no options.

+\end{figure}
+
+Immediately after the end of a list environment, \textsf{listparskip} expects to see a some text, a blank line followed by text, or an |\item|. As a general rule, text means an extra |\topsep|, and a blank line followed by text leads to an extra $\vrb\topsep+\vrb\partopsep+\vrb\parskip$. If you want to put something else, such as a box or rule, after the end of a list environment, you should type |\nullline| before the other material to prevent any spacing mishaps. This macro instructs \TeX\ to behave like it just encountered a line of text except without adding any vertical space. Table~1 shows my recommendations for code to include after a list in various cases depending on the desired result, and Table~2 shows the full rules for what happens after a list with \textsf{listparskip} in various situations. For more information, see |listparskip_code.pdf|, which is included with the \textsf{listparskip} installation and is available on \textsc{ctan}.
