From 13463d1c82d9a2a4f82d97a09ebb986b0c6cf5c1 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 16 Oct 2025 13:17:20 +0000 Subject: [PATCH 1/7] Refactor varargin to arguments blocks Replaces all instances of `varargin` with modern `arguments` blocks. This improves code clarity, enables tab-completion for optional arguments, and provides better input validation. The following functions/methods were updated: - did.datastructures.emptystruct - did.file.fileobj.fprintf - did.file.readonly_fileobj constructor and fopen - did.fun.plotinteractivedocgraph - did.fun.finddocs_missing_dependencies - did.fun.findalldependencies - did.binarydoc constructor - did.implementations.matlabdumbjsondb constructor - did.implementations.sqlitedb methods - did.implementations.sqldb constructor - did.database methods - did.document constructor and setproperties - testToolbox - parfor_test --- src/did/+did/+datastructures/emptystruct.m | 5 +- src/did/+did/+file/fileobj.m | 3 + src/did/+did/+file/readonly_fileobj.m | 11 +- src/did/+did/+fun/findalldependencies.m | 18 +- .../+did/+fun/finddocs_missing_dependencies.m | 10 +- src/did/+did/+fun/plotinteractivedocgraph.m | 19 +- .../+did/+implementations/matlabdumbjsondb.m | 14 +- src/did/+did/+implementations/sqldb.m | 8 +- src/did/+did/+implementations/sqlitedb.m | 2048 +++++++++-------- src/did/+did/binarydoc.m | 5 +- src/did/+did/database.m | 121 +- src/did/+did/document.m | 36 +- tests/+did/+test/_old/parfor_test.m | 5 +- tools/tasks/testToolbox.m | 7 +- 14 files changed, 1189 insertions(+), 1121 deletions(-) diff --git a/src/did/+did/+datastructures/emptystruct.m b/src/did/+did/+datastructures/emptystruct.m index bf31c9d..c1ce222 100644 --- a/src/did/+did/+datastructures/emptystruct.m +++ b/src/did/+did/+datastructures/emptystruct.m @@ -19,6 +19,9 @@ % end; % % See also: VAR2STRUCT + arguments (Repeating) + varargin + end if isempty(varargin) s = struct([]); @@ -37,5 +40,5 @@ end s = s([]); %} - s = cell2struct(cell(numel(fields),0), fields'); + s = cell2struct(cell(numel(fields),0), fields(:)); end diff --git a/src/did/+did/+file/fileobj.m b/src/did/+did/+file/fileobj.m index 71ca26f..49de41c 100644 --- a/src/did/+did/+file/fileobj.m +++ b/src/did/+did/+file/fileobj.m @@ -336,6 +336,9 @@ function frewind(fileobj_obj) % % Call FPRINTF (see FPRINTF for inputs) for the file associated with % FILEOBJ_OBJ. + arguments (Repeating) + varargin + end if strcmpi(fileobj_obj.permission,'r') error('DID:File:Fileobj','Cannot use fprintf() method with read-only file'); diff --git a/src/did/+did/+file/readonly_fileobj.m b/src/did/+did/+file/readonly_fileobj.m index 79d7090..39266a7 100644 --- a/src/did/+did/+file/readonly_fileobj.m +++ b/src/did/+did/+file/readonly_fileobj.m @@ -9,16 +9,23 @@ % See also: FILEOBJ methods - function fileobj_obj = readonly_fileobj(varargin) + function fileobj_obj = readonly_fileobj(options) % READONLY_FILEOBJ - create a new read-only binary file object % % FILEOBJ_OBJ = READONLY_FILEOBJ(...) % % Creates an empty FILEOBJ object.
