Dolt Commit (with examples)
Committing all staged changes with an editor
To commit all staged changes and open the editor specified by $EDITOR to enter the commit message, use the following command:
dolt commit
Motivation: This command is useful when you have made changes to your tables and want to commit those changes with a descriptive commit message. Opening the editor allows you to write a detailed and meaningful message.
Explanation: The command dolt commit is used to commit changes to your Dolt repository. By running this command, Dolt will commit all staged changes and open the editor specified by the $EDITOR environment variable. You can then enter your commit message in the editor, save the file, and exit.
Example output: After running dolt commit, the specified editor will open. You can enter your commit message in the editor:
# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
#
# On branch master
#
# Changes to be committed:
# modified: table1
# deleted: table2
#
# Untracked files:
# table3
Committing all staged changes with a specified message
To commit all staged changes with a specified commit message, use the following command:
dolt commit --message "commit_message"
Motivation: This command is useful when you want to commit changes to your tables without opening an editor for the commit message. It allows you to provide a commit message directly from the command line.
Explanation: The --message flag followed by the commit message allows you to specify the commit message directly in the command. By using this flag, you can save time and avoid the extra step of opening an editor.
Example output: After running dolt commit --message "commit_message", the specified commit message will be used for the commit. For example:
[master 1234567] commit_message
2 files changed, 10 insertions(+), 5 deletions(-)
Staging all unstaged changes before committing
To stage all unstaged changes to tables before committing, use the following command:
dolt commit --all
Motivation: This command is useful when you have made changes to your tables but forgot to stage them. By using the --all flag, you can automatically stage all unstaged changes before committing.
Explanation: The --all flag instructs Dolt to stage all unstaged changes before committing. This ensures that all changes, including those that have not been explicitly staged, are included in the commit.
Example output: After running dolt commit --all, all unstaged changes will be staged and included in the commit. For example:
[master 1234567] commit_message
2 files changed, 10 insertions(+), 5 deletions(-)
Using a specified ISO 8601 commit date
To use a specified ISO 8601 commit date instead of the current date and time, use the following command:
dolt commit --date "2021-12-31T00:00:00"
Motivation: This command is useful when you need to backdate a commit or maintain a consistent commit history with specific dates. By specifying the ISO 8601 date, you can ensure that the commit is associated with the desired timestamp.
Explanation: The --date flag followed by the specified ISO 8601 date allows you to set the commit date and time. This can be useful for historical records or maintaining a consistent commit history across distributed teams.
Example output: After running dolt commit --date "2021-12-31T00:00:00", the commit will have the specified date and time associated with it. For example:
[master 1234567] commit_message
2 files changed, 10 insertions(+), 5 deletions(-)
Using a specified author for the commit
To use a specified author for the commit, use the following command:
dolt commit --author "author_name <author_email>"
Motivation: This command is useful when you want to override the default git configuration for the author. By specifying the author’s name and email, you can attribute the commit to the desired individual.
Explanation: The --author flag followed by the author’s name and email allows you to set the author for the commit. This can be useful when you want to attribute the changes to a specific person or when the default git configuration is not accurate.
Example output: After running dolt commit --author "author_name <author_email>", the commit will be attributed to the specified author. For example:
[master 1234567] commit_message
Author: author_name <author_email>
2 files changed, 10 insertions(+), 5 deletions(-)
Allowing an empty commit
To allow creating an empty commit with no changes, use the following command:
dolt commit --allow-empty
Motivation: This command is useful when you want to create a commit that has no changes to the tables. Empty commits can be used in various scenarios, such as marking a particular point in the repository’s history or indicating a specific milestone.
Explanation: The --allow-empty flag allows you to create a commit even if there are no changes to the tables. This can be useful when you want to record a commit for non-code-related purposes or simply separate certain commits.
Example output: After running dolt commit --allow-empty, an empty commit will be created. For example:
[master 1234567] commit_message
0 files changed, 0 insertions(+), 0 deletions(-)
Ignoring foreign key warnings
To ignore foreign key warnings when committing changes, use the following command:
dolt commit --force
Motivation: This command is useful when you have foreign key constraints defined in your Dolt tables and want to skip the validation check during the commit process. Ignoring foreign key warnings can be necessary in certain cases, such as when you need to temporarily break the constraint to perform specific changes.
Explanation: The --force flag allows you to ignore foreign key warnings and commit the changes anyway. By using this flag, Dolt will skip the validation check for foreign key constraints and commit the changes to the tables.
Example output: After running dolt commit --force, the changes will be committed without checking foreign key constraints. For example:
[master 1234567] commit_message
2 files changed, 10 insertions(+), 5 deletions(-)
