When debugging using Cobalt scheme, jumping over called functions in tha call stack, at stop lines you see something like this:

which is quite hard to read. Could you please fix this?

Thank you.

We should check if panels other than the first Color preference pane have actually been initialised. This can be done by comparing the preferences set in that pane and seeing if they are all black.

I am new to Matlab and to matlab-schemer. I am running Matlab 2022b_r3 on Linux (Linux Mint 21.1 Xfce, based on Ubuntu 22.04 LTS). I have managed to use matlab-schemer to switch from the Matlab default color scheme to the cobalt scheme, but when I close Matlab and restart it, the color scheme has reverted to the Matlab default light color scheme. Is there a way to make the matlab-schemer cobalt scheme persistent so that Matlab starts up with the cobalt scheme?

Hello,

I enjoy using your schemer to implement the dracula color scheme. However it seems this package is not compatible with the new desktop. I tried reenabling dracula (which functioned in vanilla matlab) but it doesn't seem to work anymore in the new dark mode desktop.

Does anyone else encounter this problem or is it something local on my end that is causing my theme to no longer load on the dark mode desktop? The matlab developers mentioned it uses a different engine based on Matlab Online if that offers any insight.

Thank you!

Is the reason for this problem the same as #22 ?

Minor issue: CUDA is missing from the variable names_color_otherlangs in schemer_export.m

Hi, somehow I'm not able to view your .png files on GitHub. Do you know why?

It would be easier for Matlab users unfamiliar with GitHub to upload any schemes they create without leaving the Matlab environment.

To this end, it might be worthwhile setting up a server which can hold and serve the Matlab schemes, and a function which can upload them to the server using a simple UI running in Matlab.

At least these variables don't seem to exist in r2017a anymore:
ColorsUseMLintAutoFixBackground
Editor.VariableHighlighting.Automatic
Editor.NonlocalVariableHighlighting
EditorCodepadHighVisible
EditorCodeBlockDividers
Editorhighlight-caret-row-boolean

MATLAB supports syntax highlighting for a few other languages, including Java, C++ and XML. Currently these colours are not saved or set by matlab_schemer, but there is no reason why they should not be.

In fact, since these other languages take their main background and text colours from the MATLAB colours, they do not render correctly when the colour scheme is changed to a dark theme.

Since it is desirable for the colours for common syntax such as commands, comments, etc to match across the languages for any given theme, the colours should be assigned with sharing across these.

I don't expect that users who are creating a colour scheme will define the colours for all languages, so by default colours for other languages should be taken from the MATLAB syntax, but it should be possible for users to override them with custom language syntax colours.

Mathworks adds support for new languages, etc every so often. We need a way to check whether the colours exist to be exported in the version currently being run.

This could be done by checking if the version number (or better yet, release date) is higher than a threshold. Or for collections of colours which were added at the same time, checking whether they are all black. In the later case, the solution is similar to #5.

Similarly to #3, if a color scheme has the same colour for the text as the background, we should not import it. Instead just give a warning and return, or generate an error.

Line 179:
if ~isnumeric(fname)

I guess it should be
if ~isnumeric(flag_mode)

please help, thanks,

Hello,
First of all, thank you for the color schemes. As I run the dark mode, it seems to be ignoring the live scripts. The live scripts are still unchanged (regular white background). It would be helpful if you may address this.

There is a setting to control whether methods in Java should be displayed in Bold, Plain or Italic text. This needs to loaded if present in the settings file, and exported if the Java language panel is available.

Hi Scott!

Quick question: What versions of Matlab does matlab-schemer support? I'm thinking of playing around with this and maybe making a PR, and I'm wondering which language features I can use and what versions of Matlab I need to test against.

Cheers,
Andrew

Need a nice icon for on MATLAB FEX.

This will demonstrate the colours schemes currently available in scottclowe/matlab-schemes.

First of all, I'd like to thank you for your efforts 👏 , I love dark schemes ❤
I have encountered incompatibility with the App Designer Editor in MATLAB.
I think the new App Designer Editor was out of the scope once you started making the schemer.
App Designer Editor isn't affected by the schemer except for line highlighting, I had to disable it. I'll post some pictures if someone else encounters the same problem.

App Designer Editor while in "Default" scheme :

Problem occurs while in "Dark" schemes with Current Line Highlight enabled :

Disabling Current Line Highlight solves it for now:

I expect a reasonable number of people will want to create a new color scheme based on an existing one implemented for a different editor.

At the moment people can port the color scheme across by manually choosing how to map the between the entities in the two formats and converting any hexadecimal colours with color2javaRGBint. However, having to convert all the colours into RGB integer format one at a time is tedious. Also, it becomes hard to keep track of what colour the value encodes.

It would make it much easier for users to simply copy over the hexadecimal values into the template prf file. Not only would such a thing be much faster, it will also make porting a colour scheme more accessible.

This will make the format incompatible with the actual MATLAB .prf format (which does not have any hexadecimal values), but this can be fixed by importing the color scheme and exporting it again with schemer_export. After the hex values are successfully imported, the colour values will be exported into RGB int format instead.

It doesn't works well on Apple Silicon native beta version

What should I do?

I was confused at first because there weren't clear instructions on what to do to apply one of the included schemes. I didn't know that I needed to navigate to ~\Matlab\Add-Ons\Collections\MATLAB Schemer\scottclowe-matlab-schemer-2156bb9\schemes to find a file to load.

My suggestion would be to add support for quickly setting the included schemes via an API like schemer_import('monokai') and the function automatically loads the included file.

Hi Scott,

Thank you so much for implementing and sharing this repository, it's very appreciated! I'm working in R2018a, and having trouble finding the *.prf color setting for Matlab's so-called "Validation sections":

Preferences / Colors / MATLAB syntax highlighting colors / Validation sections

Within classdef files, this controls the color of per-property class type declarations, as explained here. I believe property validation was introduced into Matlab in R2016a.

Please let me know your thoughts on adding support for this, within the schemer *.prf files?

Thanks,
Brad

We should check if the user is exporting from a version of MATLAB which supports the language being exported due to the following scenario:

• User is in older version of MATLAB which does not support all the languages in the most up to date version. (Language ABC is not included in their version.)
• User imports scheme X which contains additional languages, with every language specified in the .prf file (including ABC). Now user has settings saved in matlab.prf for languages which their GUI will not present.
• User designs a new scheme for MATLAB syntax.
• User ignores advised instructions for the creation of a scheme with additional languages (which specify to create MATLAB syntax, export, import, fix additional languages) and designs the additional languages colours without importing the MATLAB syntax as a base.
• User exports the colour scheme to Y.prf, with additional languages included. The exported scheme will have colours for ABC from scheme X because these settings will exist in matlab.prf, but they do not match the background etc specified for their scheme, Y.
• User distributes their scheme, Y. Others import it into up-to-date MATLAB. Colours for ABC syntax do not work.

This scenario will presumably happen eventually, but it is not a high priority. I anticipate the majority of designers will not do anything for the Additional Languages.

Want to back this issue? Post a bounty on it! We accept bounties via Bountysource.

The code really needs to give a warning if the user has not visited all the preference panels.

Currently, the problem is a value is returned by the java getPrefs function even if the value is not available - it is just the wrong value is returned. But I can check if all the values from a panel are returned as black -16777216, and if so assume the panel is not being exported correctly.

Can someone tell me exactly what to do. I can't get it to work

The logo would work better on FileExchange if it were smaller, as then a higher resolution version would be displayed and visitors would be able to see the text.

The description of the Schemer function is that it modifies the color scheme of "the MATLAB display and GUI". The window, taskbar, and individual tabs are all part of the MATLAB GUI. In fact, aside from the "display" insets, they comprise the GUI in its entirety.

Is this a bug, a non-default option, or an oversell of the functionality?

I would be happy to be wrong, but at this point this schemer seems a bit of a bait and switch. The color contrast of dark-mode color schemes against the white GUI is eye-straining in and of itself. Thank you for implementing a method to revert to default.

Hi,
I observe another issue with the matlab_schemer.

This happens, when I export my current scheme, load another scheme from the scheme folder and then restore my saved scheme back. Also the M-Lint hints on the right side are black and not orange.

Regards,

It would be good if schemer_import mentioned in its output messages printed to the command interface that a restart of Matlab is required to ensure all colours in the GUI are up-to-date.

Hello,
I hope schemer could affect live script as well.

In develop\sample.m fprintf(fid, '%d unterminated\n, i); is not properly terminated. this can accuse issues in mcc (code compilation)

New language VRML/X3DV (virtual reality modelling) syntax highlighting was added to MATLAB by MathWorks in the 2016a release.

The following steps will need to completed:

• Create sample.wrl and/or sample.x3dv samples to demonstrate syntax highlighting in action.
• Identify the code names in matlab.prf corresponding to the new colour settings.
• Add exporting of this language to schemer_export (enabled when additional languages enabled, and version is at least M2016a)
• Add the default settings for VRML colours to default.prf
• Add importing of this language from .prf to schemer_import, using inheritance from MATLAB (.m) syntax highlighting colours when the VRML settings are omitted

Running "schemer_import" alters every tab and window region of MATLAB, except "Views" in the Project Manager:
