Hello,

I'm trying to create a script to facilitate team member when they have to update submodules inside a project to a specific tag.

I have no problem for the upadate, but io'm quite stuck to the commit phase.

I try this list of commands:

commit_message = char(strcat("Moved submodule Standard to ", standard_tag, {newline}, "Moved submodule Common to ", common_tag));

git_command = ['git commit -m ' commit_message];

system(git_command);

but, when i try to execute the script, i have this errors:

error: pathspec 'submodule' did not match any file(s) known to git

error: pathspec 'Standard' did not match any file(s) known to git

error: pathspec 'to' did not match any file(s) known to git

error: pathspec '2024R2' did not match any file(s) known to git

I suppose that my issue is related to this:

git_command = 'git commit -m Moved submodule Standard to 2024R2

Moved submodule Common to 2024R2'

It seems that the system function can't isolate correctly the "message" for the commit. How can i solve this one.

Thank you in advance.

Best regards.

Claudio

在 MATLAB Online 中打开

Try wrapping the message in quotes in the command to be executed.

commit_message = 'Moved submodule Standard to 2024R2';

Compare:

git_command1 = ['git commit -m ' commit_message]
git_command1 = 'git commit -m Moved submodule Standard to 2024R2'

and

git_command2 = ['git commit -m "' commit_message '"']
git_command2 = 'git commit -m "Moved submodule Standard to 2024R2"'

or

git_command3 = sprintf('git commit -m "%s"', commit_message)
git_command3 = 'git commit -m "Moved submodule Standard to 2024R2"'

Suppose in git_command1 one of the words in commit_message started with a - and was a valid option for "git commit"? Without the quotes, git commit should treat that as the option which may not be what you want.

Alternately, consider using the functionality provided in MATLAB itself for using Git rather than calling system to interact with git commands manually. See for example the documentation for the commit function for repo objects.
