Afterwards, configuration values found in the variable map will be used to configure the standard library function mappings that the shell will use. -Errors during configuration are non-terminal and will result in default values being returned. - -\begin{enumerate} -\item Important points to note -\label{sec:orgbff9880} -\begin{itemize} -\item When the configuration file is run, it will be run with default configuration values. -\item The user/script interpreter will be run with a \textbf{re-instantiation} of the standard library, using the previously defined configuration variables. -\item Variables and functions defined during configuration will carry over to the user/script interpreter, allowing the user to load any number of custom functions and variables. -\end{itemize} -\end{enumerate} - -\subsubsection{Configuration Values} -\label{sec:orgf8edfc5} -\begin{itemize} -\item CFG\textsubscript{RELISH}\textsubscript{POSIX} (default 0): when on, enables POSIX style job control. -\item CFG\textsubscript{RELISH}\textsubscript{ENV} (default 1): when on, interpreter's variable table and environment variable table are kept in sync. -\item CFG\textsubscript{RELISH}\textsubscript{PROMPT} (default (echo "λ ")): A \textbf{function} definition which is called in order to output the prompt for each loop of the REPL. -\end{itemize} -Note: CFG\textsubscript{RELISH}\textsubscript{PROMPT} is only loaded once and will be ignored after initial configuration. - -\subsection{Compilation} -\label{sec:org39d838c} -\begin{verbatim} -cargo build -\end{verbatim} - -\subsection{Testing} -\label{sec:org6e03460} -\begin{verbatim} -cargo test -\end{verbatim} - -\subsection{Running (the main shell)} -\label{sec:orgd463ecf} -\begin{verbatim} -cargo run src/bin/main.rs -\end{verbatim} - -\section{Guide to codebase} -\label{sec:orgd69534c} -\subsection{\url{tests} directory} -\label{sec:orgb50a02a} -Start here if you are new. -Most of these files have unimplemented tests commented out in them. -Contributions that help fill out all of these tests -\subsubsection{Eval tests: \url{tests/test\_eval.rs}} -\label{sec:orga1b1d34} -These are particularly easy to read and write tests. - -\subsubsection{Func tests: \url{tests/test\_func.rs}} -\label{sec:orge9d0267} -You can consider these to extend the eval tests to cover the co-recursive nature between eval and func calls. - -\subsubsection{Lex tests: \url{tests/test\_lex.rs}} -\label{sec:org594467d} -These tests verify the handling of syntax. - -\subsubsection{Lib tests: (tests/test\textsubscript{lib}*)} -\label{sec:org9bec093} -These tests are unique per stdlib module. - -\subsection{\url{src} directory} -\label{sec:org76b8e4f} -This directory contains all of the user facing code in relish. -Just a few entries of note: -\subsubsection{segment: \url{src/segment.rs}} -\label{sec:orge669586} -This file lays out the \sout{spiritual} \sout{theological} \sout{ideological} \sout{theoretical} mechanical underpinnings of the entire interpreter. -The entire LISP machine centers around a singlet or pairing of datum. -The \texttt{Ctr} datatype provides an abstraction for which any type of data, including a \texttt{Seg} can be a datum. -The \texttt{Seg} datatype provides a mechanism to hold a single datum or a pair of datum. It is implemented as two \texttt{Ctr\textasciitilde{}s: \textasciitilde{}car} and \texttt{cdr}. -A primitive type system is provided through the Rust Enum datatype. A number of utility functions follow. - -\subsubsection{lib: \url{src/lib.rs}} -\label{sec:org411af26} -This defines a library that can be included to provide an interpreter interface within any Rust project. -It includes the core interpreter mechanisms, full stdlib, and the configuration system. -Your project can use or not use any number of these components. They can certainly be used to support language development for other LISP machines, -or even other languages. - -\subsubsection{stl: \url{src/stl.rs}} -\label{sec:org35c6136} -This defines the \texttt{get\_stdlib} function. -This function takes in a Variable Table (likely containing custom configuration) and returns a Function Table for use in an interpreter. -Any new addition to the stdlib must make its way here to be included in the main shell (and any other shell using the included \texttt{get\_stdlib} function). -You may choose to override this function if you would like to include your own special functions in your own special interpreter, or if you would like to pare down the stdlib to a small minimal subet of what it is. - -\subsubsection{bin: \url{src/bin/}} -\label{sec:org02ca0c3} -This contains any executable target of this project.
