Configure Git source control-MATLAB and Simlink- MathWorks in Germany (2023)

organize somethingidiotsource of control

You can use Git™ source control in MATLAB^®to manage files and collaborate with others. With Git, you can track changes to your files and retrieve specific revisions later. For more information, seeUse Git no MATLAB.

Before using Git, follow these steps to configure it for MATLAB:

Register your binaries with Git to avoid file corruption. (Mandatory for all systems)
Configuring MATLAB for Git on Windows^®system. (Recommended for Windows systems)
Configure MATLAB to use Git SSH authentication or install the Git Credential Helper to avoid frequent login prompts. (optional)
Disable Compression for Simulink^®Templates for reducing the size of the Git repository. (optional)
Configure Git to use Git LFS if you are working with large files. (optional)
Configure Git to use MATLAB for diffs and joins. (optional)

Prior to R2020b, you needed to install the Git command line client to use Git to merge branches in MATLAB. For more information, seeInstall the Git client from the command line.

register binaries withidiot

If you use third-party source control tools, you must register the MATLAB and Simulink file extensions as.mlx,.women,.Kitten,.mlapp,.mdl,.slx,.mdlp,.slxp,.sldd, EU.PAGEas binary formats. Also register MEX file extensions like.mexa64,.mexmaci64, EU.mexw64. If you don't register extensions, these tools can corrupt uploaded files by changing newlines, token expansion, keyword substitution, or trying to auto-merge them. If you use source control tools outside of MATLAB or if you try to transfer files from MATLAB without first registering the file formats, corruption can occur.

Also make sure other file extensions are registered as binary to avoid corruption during check-in. Check and record file extensions like.xlsx,.jpg,.pdf,.docx, etc.

To register binary file extensions with Git, add them to the file.gitattributesfile. If you create a new project that uses Git source control or switch an existing project from another source control system to Git source control, MATLAB will automatically create.gitattributesfile and populates it with a list of popular binaries to register.

E.gitattributesThe file is not automatically created, you can create a file containing a list of popular binaries to register. In the MATLAB command window, type:

copyfile(whole file(matlabroot,'Tool box','common',"cmenlace","idiot","support_files",..."mwgit attributes"), complete file (password,".attributosgit"))

Alternatively, to create a blank.gitattributesfile, type:

To set upMATLABTo doidiotTHATwindows

On Windows systems, if you are working with files with long paths, enable long path support. Also, to use Git bindings with MATLAB, install Cygwin and add it to the MATLAB library path. Git hooks are custom scripts that can be triggered by operations like commit, merge, and receiving push commits.

Enable long path support (recommended)

To enable long path support on Windows, run this command in MATLAB:

!git config --global core.longpaths verdadero

Install Cygwin (optional)

To install Cygwin on Windows and add it to the MATLAB library path:

Download and run the installer fromhttps://www.cygwin.com/.

Open not MATLABroute_library.txt.

edit(whole file(matlabroot,"Tool box","local","library path.txt"))

Add Cygwin bin folder location to the endroute_library.txt, For example,C:\cygwin64\bin.

#### ARQUIVO: Librarypath.txt#### Entradas:## en jnifile_path## en [alpha,glnx86,sol2,unix,win32,mac]=jnifile_path## en $matlabroot/jnifile_path## en $jre_home/ ruta_al_jnifile##$matlabroot/bin/$arch$matlabroot/sys/jxbrowser/$arch/libC:\cygwin64\bin

If you don't have permission to edit the fileroute_library.txtfile, viewFind native method libraries.

Restart MATLAB.

To set upMATLABto useidiotSSH Authentication

To avoid frequent login prompts when interacting with a remote repository using HTTPS, add a new public key and clone the repository using SSH. This table provides instructions for configuring MATLAB to use SSH authentication based on your operating system.

installidiotcredential assistant

De R2021a

To configure MATLAB to remember usernames and passwords when using Git, install the Credential Helper. The recommended credential helper for all platforms is Git Credential Manager Core.

For example, to install Git Credential Manager Core on Windows, download and run the Git installer for Windows following the instructions atInstall the Git client from the command line. cSelect credential wizardinstaller section, selectGit Credential Manager Coreas a credential helper.

To remove saved credentials from the Git repository, follow the instructions for your operating system.

Operational system	Instructions
windows	To reset Git credentials for the repository, in the Credentials Manager on pageWindows Credentialstick, delete the entries belowgeneric credentials.
Linuxmac operating system	To reset your repository's Git credentials, type: echo "url=https://github.com/myrepo.git" \| discard git credentials

Turn off compression forsimultaneous callModels to follow

You can reduce the size of your Git repository by saving Simulink models without compression. Disabling compression creates larger SLX files on disk, but reduces the repository size.

To use this setting with new SLX files, create templates using a template template with SLX Compression set to none. For existing SLX files, set compression and save the template. For more information, seeSet the SLX compression level(Simulink).

To set upidiotto useidiotLFS

De R2021a

If you work with large files, configure Git to use Git Large File Storage (LFS) by installing Git from the command line and configuring LFS.

For example, to use Git LFS on Windows, download and run the Git installer for Windows following the instructions atInstall the Git client from the command line. cselect componentsin the installer section of Git for Windows, select the fileGit LFS (large file support)EUAssociate .sh files to be run with Bashoptions.

MATLAB does not support the Git LFS lock. Also, MATLAB does not support LFS commands likepista git lfs. To use!git lfs pistaInstead of.

To use

Git LFS uses Git hooks. Make sure you have Cygwin installed. For more information, seeConfiguring MATLAB for Git on Windows.

To set upidiotto useMATLABcompare and merge

You can configure Git to use the MATLAB diff tool for diffs and merges. MATLAB diff tool provides MathWorks merge tools^®as live scripts, MAT, SLX or MDL files. You can use the auto-merge tool in Git to automatically merge branches containing changes in different subsystems into the same SLX file.

For more information on configuring Git to use the MATLAB Reference Tool, seeCustomize external source control to use MATLAB for compare and join.

Install the Git client from the command line

To use Git LFS or the credential helper, you must install the Git client from the command line and install it system wide. Prior to R2020b, you needed to install the Git command line client to use Git to merge branches in MATLAB.

To verify that Git is installed, enter the command!gitin the MATLAB command window. If the command returns nothing, you must install Git from the command line. This table provides instructions for installing Git from the command line based on your operating system.

Operational system	Instructions
windows	Download and run the installer fromhttps://gitforwindows.org/. cCustomizing your PATH environmentsection, select an installation optiongit on the command line and also in third-party software. This option adds Git to your`PATH`variable and does this system-wide so that MATLAB can communicate with Git. In the end-of-line conversion settings section, select an optionCheck Windows style, confirm Unix-style line endingsoption. The end-of-line format cannot be enforced across computers and users, but consistent line endings can be supported for text files in the format`.gitattributes`each file in the repository. Restart your system for the changes to take effect.
linux	Git is available for most distributions. Install Git for your distribution. For example on Debian^®, install Git by typing: sudo apt-get instalar git
mac operating system	On Mavericks (10.9) or later, launch Git in a terminal window. If you don't already have Git installed, you'll be prompted to install Xcode's command line tools. For more information, seehttps://git-scm.com/doc.
