Our design follows \emph{Programs as Diagrams}~\cite{pavlovic2023programsdiagramscategoricalcomputability}: programs are typed string diagrams equipped with cartesian data services (copy and delete), a distinguished program type with decidable equality, and a universal evaluator family. +In our case study, we instantiate this evaluator for the POSIX Shell Command Language~\cite{posix-2024} using \texttt{subprocess.run}. In this interpretation, sequential composition (\texttt{>>}) realizes shell-style pipelines and monoidal tensor (\texttt{@}) models independent process branches. \texttt{Copy}, \texttt{Merge}, and \texttt{Trace} arise naturally from the monoidal computer representation, extending the Shell Command Language with primitive fan-out, fan-in, and feedback operators. The resulting system highlights the practical applications of categorical computability: developers can construct programs diagrammatically, analyze them compositionally, and translate them to a chosen target language. + +% We present an implementation of the Run language in DisCoPy, along side a practical universal evaluator for Operating System processes. +% Following the theory of Programs as Diagrams, we write and publish a package 'discopy-computer', with the Computer, Program and Execution categories, Run morphism, and Compiler functor to move from an abstract program definition to a callable object in the category of Python functions provided by the framework. + +% treating programs as topological string diagrams captures both composition and correctness. + +% The Compiler functor maps morphisms to operating-system subprocesses through a functor into \texttt{discopy.python.Function}, where \texttt{subprocess.run} acts as a universal evaluator. In this setting, vertical composition (\texttt{>>}) models Unix-style pipelines, while the monoidal tensor (\texttt{@}) models parallel subprocess execution. +% Symmetry and trace operators encode feedback and cyclic pipelines, and explicit fan-out/fan-in combinators realize practical IO multiplexing via \texttt{tee} and \texttt{cat}. + +% The result is a compact bridge between the Monoidal Computer theory and the execution of Python programs using DisCoPy. + +% By leveraging DisCoPy's diagrammatic tooling, the approach combines formal clarity with + +% : developers can design, reason about programs graphically their behavior, and execute them with standard OS primitives. practical subprocess orchestration for high-concurrency pipeline design. + + + +\keywords{Categorical computability \and String diagram.} +\end{abstract} +% +% +% + +\section{Motivation} + +\paragraph{Graphical calculus} +String diagrams provide a rigorous graphical calculus for monoidal categories~\cite{Selinger_2010}. Sequential composition is represented by vertical wiring, while tensor product is represented by horizontal juxtaposition. Additional structural features, such as symmetries and traces, are encoded topologically. Diagram deformations that preserve connectivity correspond to sound equational reasoning. + +\paragraph{Computing with string diagrams} +This perspective motivates treating programs as diagrams~\cite{pavlovic2023programsdiagramscategoricalcomputability}. The universal evaluator is the central primitive from which sequential and parallel composition, and partial evaluation. +DisCoRun operationalizes this approach on top of DisCoPy, the Python toolkit for monoidal categories. In this setting, diagrams are typed program objects that support composition, rewriting, and functorial interpretation into executable backends (e.g., Python functions). We instantiate this machinery with the monoidal computer interface of \emph{Programs as Diagrams}: \texttt{RUN} is the single primitive induced by the running surjection, while richer behaviors are derived by composing diagrams. + + +% TODO "intentions" column on the left +% with eq and diagram +% \begin{figure} +% \centering +% \begin{subfigure}[b]{0.4\textwidth} +% \centering +% \begin{minted}{python} +% Copy(3) >> ( +% Command(["cat"]), +% Command(["grep", "-c", "x"]), +% Command(["wc", "-l"]), +% ) >> Merge(3) +% \end{minted} +% \caption{The program equation.} +% \end{subfigure} +% \hfill +% \begin{subfigure}[b]{0.55\textwidth} +% \centering +% \includesvg[width=\textwidth]{merge-diagram.svg} +% \caption{The program diagram.} +% \end{subfigure} +% \caption{Diagrams imbue visual intuition with formal guarantees.} +% \label{fig1} +% \end{figure} +\begin{figure}[htbp] + \centering + % LEFT COLUMN: Stacked vertically + \begin{minipage}[c]{0.48\textwidth} + \begin{subfigure}[b]{\textwidth} + \centering + \begin{minted}{python} +Copy(3) +>> ( + Command(["cat"]), + Command(["grep", "-c", "x"]), + Command(["wc", "-l"]), +) +>> Merge(3) + \end{minted} + \caption{Program equation.} + \end{subfigure} + + \vspace{0.5cm} % Vertical gap between the stacked items + + \begin{subfigure}{0.5\textwidth} + \centering + \includesvg[width=\textwidth]{parallel-diagram.abstract.svg} + \caption{Abstract program diagram.} + \label{fig:bottom_left} + \end{subfigure} + \end{minipage} + \hfill + % RIGHT COLUMN: Single tall item + \begin{minipage}[c]{0.45\textwidth} + \begin{subfigure}{\textwidth} + \centering + % Adjust height to match the combined height of the left column + \includesvg[width=\textwidth]{parallel-diagram.svg} + \caption{Runnable diagram} + \label{fig:right_side} + \end{subfigure} + \end{minipage} + + \caption{Diagrams imbue visual intuition with formal guarantees.} + \label{fig:example1} +\end{figure} + +\section{POSIX Shell Command Language Case Study} + +\subsection{Shell Evaluator} +This case study instantiates the evaluator on \texttt{IO} wires using \texttt{subprocess.run}.

It keeps commands readable as data. +3. It gives agents and humans one representation they can both inspect and revise. +4. It supports interactive work, saved command documents, and generated command codebases. + +Keep the boundary in mind: +1. Mytilus provides structured command composition. +2. Platform command availability still depends on the underlying environment. + +## State Scope And Tool Limits + +Avoid vague scope words such as `default`, `global`, or `forever` unless the boundary is explicit. + +When describing what mytilus changes: +1. Say `this session` when the behavior only applies to the current conversation. +2. Say `this repository` when the guidance comes from a repo-local `SKILL.md`. +3. Say `VS Code integrated terminal` when the change only affects VS Code terminal profiles. +4. Say `operating system login shell` when the change affects the user's actual shell outside VS Code. +5. Say `Codex platform default` only for true global behavior outside the repository and outside the current session. + +When working through Codex developer tools: +1. Explain that `exec_command` and PTY sessions are shell-based transports. +2. Prefer mytilus in user-facing examples, generated YAML command documents, and actual `bin/mytilus` or REPL demonstrations. +3. Do not imply that shell-backed tool logs mean the mytilus skill is inactive. +4. If a task needs shell-native tools such as `rg`, `sed`, `git`, or `pytest`, say so briefly instead of pretending the transport changed. + +When demonstrating the skill: +1. Prefer `bin/mytilus -c` or the REPL over paraphrase alone. +2. Show the YAML document and its output. +3. Treat any embedded `bash -c` fragment as an explicit subtool, not as mytilus syntax. + +## Build YAML As A Codebase + +Create YAML documents while working instead of treating them as a final export step. + +Use this workflow: +1. Write command documents incrementally as the task evolves. +2. Treat related YAML documents as a codebase, not as isolated snippets. +3. Put that codebase in the user's preferred location. +4. Organize files so humans and agents can navigate and revise them easily. + +Use helper scripts when they improve speed or reliability: +1. Generate or refactor YAML documents with scripts when repetition would otherwise cause drift. +2. Use any scripting language the user prefers. +3. Keep helper scripts subordinate to the YAML codebase rather than replacing it. +4. Let scripts support document creation, transformation, validation, or synchronization. + +## Write Command Documents + +Use a tagged scalar for command invocation: + +```yaml +!echo Hello world! +``` + +Use a sequence for pipeline composition: + +```yaml +- !grep grep +- !wc -c +``` + +Use a mapping for structured grouping: + +```yaml +? !printf left +? !printf right +``` + +Use tagged mapping entries to build explicit command arguments: + +```yaml +!echo +? foo +? bar +``` + +## Use YAML As A Heredoc + +Treat a YAML document as the mytilus equivalent of the multiline inline scripts that agents often send through shell heredocs. + +Agents commonly use heredocs to do this: +1. Open one inline multiline block. +2. Put the whole script inside it. +3. Hand that block to a shell or interpreter. + +Use YAML for the same operational purpose when the work is really a command document rather than raw shell text. + +Prefer YAML-as-heredoc when: +1. The agent is about to emit a multiline inline script. +2. The logic is better expressed as commands, pipelines, mappings, and substitution than as shell punctuation. +3. The document should stay readable and editable as structured data. +4. The same inline block should be understandable by both humans and agents. +5. You want the multiline unit to remain valid YAML before execution. + +Use a plain shell heredoc only when the inline block truly needs to be shell script text. + +Follow the practical rule: +1. If the agent is about to write a multiline inline shell script, first ask whether the block is actually a mytilus command document. +2. If yes, write YAML. +3. If no, keep the heredoc or embed an explicit shell fragment inside YAML. + +## Use Mappings Deliberately + +Use mappings to express grouped parallel work that shell punctuation usually hides. + +Use a shared parent command with grouped child branches: + +```yaml +!cat examples/shell.yaml: + ? !wc -c + ? !grep grep: !wc -c + ? !tail -2 +``` + +Read this as: +1. Run one shared upstream command. +2. Feed its output into multiple child branches. +3. Keep the grouping explicit in the YAML structure. + +Understand the nature of the parallelism: +1. Treat the parent command as one shared source of input for all child branches. +2. Treat each child as an independent branch that receives that same upstream output. +3. Treat the result as structured fan-out and merge, not as shell punctuation spread across several unrelated lines. +4. Expect branch outputs to be combined in branch order, so the document structure still determines the visible output order. + +Use mapping children for command substitution when a parent command needs values produced by subcommands: + +```yaml +!echo +? Hello +? !printf {"%s!", "World"} +``` + +Read this as: +1. Pass `Hello` as a plain argument. +2. Run the tagged child as a subprogram. +3. Inject its output into the parent command's argv. + +Use shell intuition only as a translation aid: + +```bash +echo Hello "$(printf "%s!" World)" +``` + +Treat substitution as value production, not as text pasted back into a shell parser. + +## Use The REPL + +Treat the REPL as document-oriented input: +1. Enter one YAML document per submission. +2. Build multiline documents before executing them. +3. Think in documents, not in POSIX shell lines. + +Use the interactive controls as follows: +1. Press `Ctrl+J` to insert a newline inside the current document. +2. Press `Enter` to submit the current document. +3. Press `Ctrl+D` to exit when the current document is empty. + +Preserve transcript output verbatim and in order when logging or replaying sessions. + +## Configure VS Code + +When a user wants mytilus as the default shell in VS Code: +1. Explain that this changes VS Code's integrated terminal default profile, not the operating system login shell and not Codex's platform defaults. +2. Prefer `Preferences: Open User Settings (JSON)` for a global VS Code change. +3. Prefer workspace settings only when the user wants the behavior limited to one repository. +4. Define a profile under the platform-specific `terminal.integrated.profiles.*` key and set `terminal.integrated.defaultProfile.*` to that profile name. +5. Use an absolute path in global settings because repository-relative paths are fragile outside one workspace. +6. Remind the user that the change applies to newly created terminals. + +Use this Linux example: + +```json +{ + "terminal.integrated.profiles.linux": { + "mytilus": { + "path": "/absolute/path/to/repo/bin/mytilus" + } + }, + "terminal.integrated.defaultProfile.linux": "mytilus" +} +``` + +Translate the setting suffix by platform: +1. Use `.linux` on Linux. +2. Use `.osx` on macOS. +3. Use `.windows` only with a Windows-runnable entrypoint such as a `.cmd` wrapper or a WSL launcher, because `bin/mytilus` is a POSIX shell script. + +If the user prefers UI steps instead of JSON: +1. Tell them to open `Terminal: Select Default Profile`. +2. Tell them to choose the `mytilus` profile. +3. Tell them to open a new terminal. + +## Compose With Explicit Shells + +Prefer direct command structure over shell re-parsing whenever possible. + +Use an explicit shell as one component of a mytilus program when the task genuinely depends on shell grammar, such as: +1. Shell builtins. +2. Redirection-heavy one-liners. +3. Loops or compound shell conditionals. +4. Shell-specific expansion rules. + +Keep the outer document in YAML whenever possible and isolate only the shell-dependent fragment. + +Use the hybrid pattern: + +```yaml +!bash {-c, "for x in a b c; do echo \"$x\"; done"} +``` + +Prefer this style when only one part of the task needs shell grammar: +1. Keep the mytilus document as the main program structure. +2. Derive only the scripted fragment into `bash -c`, `sh -c`, or another explicit shell command. +3. Keep pipelines, grouping, and surrounding dataflow in YAML when they do not need shell parsing. + +Treat the shell fragment as an explicit embedded tool, not as mytilus's native grammar. + +## Communicate Clearly + +Use mytilus as both an execution format and a communication format: +1. Keep documents readable. +2. Keep structure visible. +3. Prefer explicit grouping over clever punctuation. +4. Write examples that humans and agents can both follow quickly. + +Use mytilus to make command intent inspectable, reviewable, and easier to transform. diff --git a/widip/__init__.py
