matlab-ts-mode is a [[https://tree-sitter.github.io/tree-sitter][tree-sitter]], based MATLAB mode using
11+
https://github.com/acristoffers/tree-sitter-matlab. This new MATLAB mode is a replacement
12+

- More accurate fontification, we now identify language elements accurately and use
17+
more faces to color them.

Create issue for this:
22+
#+begin_src matlab-ts
23+
x = [1 2; 3 4];
24+
y = x'' % this is valid double transpose where matlab-mode gets it wrong

Function identification, see https://github.com/mathworks/Emacs-MATLAB-Mode/issues/48

- Fixed fontification of "%% section" to require that the be the start of a comment and
32+
on their own line.

- In comments, we now highlight =FIXME=, =TODO=, and =XXX= markers.

36-
on their own line.
36+
- Now fontify all MATLAB/Simulink factory builtin provided functions, class
37+
methods/properties, enums, etc. Note, if you override a builtin function with a variable,
38+
the variable creation/assignment will be colored as a variable, but the use will continue to
39+
be a function. To avoid this confusing state, use variable names that collide with builtin
40+
items.

5656

57-
+ Auto-indentation of end, see https://github.com/mathworks/Emacs-MATLAB-Mode/issues/33
57+
+ There's no longer prompting if you want functions to have end's. This is now computed
58+
automatically.
5859

59-
+ Fixed cell and matrices indent alignment problems
60+
+ Improved fill-paragraph, =M-q=, which will now fill comments and when not in a comment, indent
61+
the current function or statement.

Running =C-x 4 a= (add-change-log-entry-other-window) will now insert the name of the function
68+
or classdef for the current point.
6869

69-
+ Change Log command now work with MATLAB *.m files.
70+

Running =C-x 4 a= (add-change-log-entry-other-window) will now insert the name of the function
72-
or classdef for the current point.
73+
+ On save fix of function/classdef name now handles buffer names that aren't valid MATLAB
74+
identifiers. On save fix of function/classdef name handles buffers not associated with files
75+
on disk. Also fixed cases where detection of scripts failed.
7376

74-
+ Added support for =M-x outline-minor-mode=. Outline headings are =function='s, =classdef='s,
75-
and "%% heading" comments.
77+
+ Improved handling of single quotes for =M-x electric-pair-mode=. These will automatically
78+
pair
79+
- Single quote when used to create a single-quoted string, but not when used elsewhere,
80+
e.g. a matrix transpose.
81+
- Double quotes for a double-quoted string.
82+
- Parenthesis =()=, Vectors, =[]=, and Cells ={}=.

85+
or double quote.

#+begin_example
90+
C-M-f Move forward by s-expression, forward-sexp
91+
- If point is on the start of an s-expression, move to the end.
92+
- If point is on the end of an s-expression, move to the start of the next s-expression
93+
at the same level. If there is no next s-expression, no movement occurs.
94+
C-M-b Move backward by s-expression, backward-sexp
95+
- If point is on the end of an s-expression, move to the start.
96+
- If point is on the start of an s-expression, move to the start of the prior s-expression
97+
at the same level. If there is no prior s-expression, no movement occurs.
98+
C-M-SPC Mark s-expression, place point at beginning of sexp and mark at the end, mark-sexp
99+
C-M-@ Same as C-M-SPC.
100+
C-M-k Kill s-expression, kill-sexp
101+
C-M-t Transpose s-expressions, transpose-sexp
102+
#+end_example
90103

91-
+ Improved (more predictable) s-expression commands
104+
+ Improved sentence commands. Also fixes bugs, e.g. M-a in old matlab-mode can result in error
105+
"Wrong number of arguments: (0 . 0), 1" and now works in matlab-ts-mode.

- To comment or uncomment code use select the code and type =M-;= which is the standard
118+
way to do this in Emacs. The older =C-c ;= and =C-c :" matlab only comment and uncomment
119+
commands no longer exist.

122+
using LSP mode.

125+
Sections -> Run Section (C-c C-<return>)= or and the older =MATLAB -> Run Code Section=
126+
(matlab-shell-run-code-section) because it was duplication and wasn't correctly handling all

+ Builtin items such as namespaces, functions, classes, enumerations, etc. provided by the
130+
MATLAB/Simulink products are shown in =font-lock-builtin-face=. Using a different face for
131+
builtins vs items you created improves readability. It also helps to avoid mistakes where you
132+
override a builtin with a variable. The number of builtin items in the MATLAB/Simulink

R2025a.update1 product family is 153,627.
