Editor to share with you how linux uses Tig to browse Git logs. I believe most people don't know much about it, so share this article for your reference. I hope you can learn a lot after reading this article. Let's learn about it together.

Tig is more than just a text interface for Git. Here's how it enhances your daily workflow.

If you use Git as your version control system, you may have convinced yourself that Git is a complex beast. It's a great tool, but browsing the Git repository can be troublesome. So tools like Tig have emerged.

From the Tig man page:

Tig is the ncurses-based text interface of git (1). It is primarily used as a Git repository browser, but it also helps to temporarily commit changes at the block level and acts as an output pager for various Git commands.

This basically means that Tig provides a text-based user interface that can be run in a terminal. Tig makes it easy for you to browse your Git log, but it can do much more than let you jump from the last submission to the previous one.

Many of the examples in this quick start Tig are taken directly from its excellent man pages. I strongly suggest you read it for more information.

Install Tig

Fedora and RHEL: sudo dnf install tig

Ubuntu and Debian: sudo apt install tig

MacOS:: brew install tig

For more information, see the official installation instructions.

Browse for submissions in the current branch

If you want to browse the latest submission in the branch, enter:

Tig

okay. This three-character command will launch a browser where you can browse the submissions in the current branch. You can think of it as a wrapper for git log.

To browse these outputs, you can use the up and down arrow keys to move from one submission to another. Pressing enter will split the window vertically, with the selected submission on the right. You can continue to browse up and down in the submission history on the left, and your changes will be displayed on the right. Use k and j to navigate up and down line by line, and the-and spacebar to turn the page up and down on the right. Use Q to exit the right pane.

Searching for tig output is also easy. Use / (forward) or? (backward) to search in the left and right panes.

Searching Tig

This is enough to allow you to browse your submission information. There are many key bindings here, but clicking h will display the help menu, where you can find its navigation and command options. Can you still use / and? To search the help menu. Use Q to exit the help.

Browse for changes to a single file

Because Tig is a wrapper for git log, it can easily accept the same parameters that can be passed to git log. For example, to browse the submission history of a single file, enter:

Tig README.md

Compare it with the output of the encapsulated Git command to see more clearly how Tig enhances the output.

Git log README.md

To include a patch in the original Git output, you can add the-p option:

Git log-p README.md

If you want to narrow the submission to a specific date range, try the following:

Tig-after= "2017-01-01"-- before= "2018-05-16"-- README.md

Once again, you can compare it with the original Git version:

Git log-- after= "2017-01-01"-- before= "2018-05-16"-- README.md browsing who changed the file

Sometimes you want to know who made changes to the file and why. Command:

Tig blame README.md

The device is essentially an encapsulation of git blame. As you might expect, it allows you to see who is the last person to edit the specified line, and it also allows you to see the submission that introduced the line. This is a bit like what vim's vim-fugitive plug-in provides: the Gblame command.

Browse your temporary storage area

If you are like me, you may have made a lot of changes in your temporary storage area. It's easy to forget them. You can view the latest items in the staging office in the following ways:

Git stash show-p stash@ {0}

You can find the second latest project in the following ways:

Git stash show-p stash@ {1}

and so on. If you call these commands when you need them, you will remember them more clearly than I do.

Like the Git command above, Tig can easily enhance your Git output with a simple call:

Tig stash

Try to execute this command in a warehouse that has temporary storage. You will be able to browse and search for your temporary items and quickly browse through your changes.

Browse your quotation

Git ref refers to the hash value of something you submit. This includes files and branches. Use the tig refs command to browse through all the ref and drill down into specific submissions.

Tig refs

When you are done, use Q to return to the previous menu.

Browse git status

If you want to see which files are temporarily saved and which are not tracked, use tig status, which is an encapsulation of git status.

Tig status

Browse git grep

You can use the grep command to search for expressions in a text file. The command tig grep allows you to browse the output of git grep. For example:

Tig grep-I foo lib/Bar

It allows you to browse the lib/Bar directory to search for foo output in a case-sensitive manner.

Output to Tig through standard input pipeline

If you want to pass the list of submitted ID to Tig, you must use the-- stdin flag so that tig show can read from standard input. Otherwise, tig show starts without input (a blank screen appears).

Git rev-list-- author=olaf HEAD | tig show-- stdin add a custom binding

You can customize Tig using the rc file. The following is an example of how to add some useful custom key bindings according to your preferences.

Create a file named .tigrc in the home directory. Open ~ / .tigrc in your favorite editor and add:

# apply selected staging content bind stash a!? git stash apply% (stash) # discard selected staging content bind stash x!? git stash drop% (stash)

As mentioned above, run tig stash to browse your temporary storage. However, with these bindings, you can press a to apply the item in staging to the warehouse, and press x to delete the item from the staging. Keep in mind that you can't execute these commands until you browse the temporary list. If you are browsing temporary items, please type Q to exit the view, and then press an or x to get the desired effect.
