- CLion provides a user interface for Git, which you can enable in the VCS menu. It automatically detects all Git roots within the workspace. This will include bazel-drake, which is a Bazel-internal detail.
- CLion and git submodules Follow. Olof Edlund Created November 22, 2016 21:34. Hi, What is the best way to use git repos that has submodules?
- Git Flow Integration.
- Working with CLion Opening the project. Clone the project using Git (don't forget the submodules) into a folder of your choice. After that you can open the project. When starting CLion it either shows you a welcome screen with your recent projects, or it goes straight to IDE-mode.
How to draw hairstyles. If you are developing softwares on cross-platform projects (e.g. Windows/Linux/MacOS), you will find that the line endings is sometimes pretty annoying, especially when reading files.
Outline
- Line Endings Format
- Control Characters: Carriage Return (CR), Line Feed (LR)
- For Cross-Platform Projects: Auto-Correct Line Ending Format (Git)
I. Line Ending Formats
About one and a half years ago I wrote a blog post about using CLion for embedded software development. Long story short, I used an ST demo board (reflashed into SEGGER JLink-compatible probe), STM32CubeMX code generator, GCC ARM toolchain, and SEGGER Ozone on-chip debugger to run some demonstration project.
There are mainly two kinds of control characters for line endings, Carriage Return (CR, the code is r) and Line Feed (LF, the code is n).
On different OS, different line ending is used.
- OSX, Linux: LF (n)
- Legacy MacOS (MacOS 9 and earlier): CR (r)
- Windows: CR LR pair (rn)
- Carriage return points the cursor to the beginning of the line horizontly and Line feed shifts the cursor to the next line vertically. Combination of both gives you new line(n) effect.
You can find more details on Wiki.
II. Look Up / Change Text’s Terminators
If you download a file to your system from a different OS. You might notice that some weird behaviors occurs while processing the strings. Probably it is a result of inconsistency between text and OS.
Ubuntu Users
For Ubuntu users, you can simply use
file
command to see the files line ending format.Map of beaujolais crusades. To convert from DOS/Windows to Unix:

Editor Users (Take JetBrains for Example)
Lots of editors/IDE allow user to set up line separators (line endings) for newly created files, and change line separator style for existing files.

III. Auto-Correct Git’s Text Line Ending

If you are working on cross-platform projects, the subtle difference above could be incredibly annoying; many editors on Windows silently replace existing LF-style line endings with CRLF, or insert both line-ending characters when the user hits the enter key.
In order to gaurantee that the code fits your OS system, there are two common ways to set things up so git will git to auto-correct line ending formats.
Solution 1: Git Configuration
Git can handle this by auto-converting CRLF line endings into LF when you add a file to the index, and vice versa when it checks out code onto your filesystem. That is, to change core.autocrlf. (You could add —-global to set all repos)
There are three values for this variable: true, input, false.
Clion Git Submodules
- Set core.autocrlf=true: Git will auto-convert CRLF line endings into LF when you add a file to the index; Git will convert LF to CRLF when checking out code. (For cross-platform projects, this is the recommended setting on Windows)
- Set core.autocrlf=input: When committing text files, CRLF will be converted to LF. Git will not perform any conversion when checking out text files. (For cross-platform projects this is the recommended setting on Unix, but don’t use input under windows)
- Set core.autocrlf=false: Git will not perform any conversions when checking out or committing text files. (Choosing this option is not recommended for cross-platform projects)
Solution 2: .gitattribute
It is a good idea to keep a .gitattributes file as we don’t want to expect everyone in our team set their config. This file should keep in repo’s root path and if exist one, git will respect it.
- This will treat all files as text files and convert to OS’s line ending on checkout and back to LF on commit automatically.

IV. Ignore File Mode
After you clone a repo, you may find that even if we set up
core.autocrlf
as we described above, it is still saying that files have been modified. The reason is that the file permissions may not be supported. (Linux has more complete access rights -rwxrwxrwx than Windows) You could try and set core.fileMode
to false.If you set core.fileMode to false, make sure that executable’s and script’s permission is well handle.
As https://stackoverflow.com/a/1580644 suggested,
core.fileMode
is not the best practice and should be used carefully. This setting only covers the executable bit of mode and never the read/write bits. In many cases you think you need this setting because you did something like chmod -R 777
, making all your files executable. But in most projects most files don’t need and should not be executable for security reasons.The proper way to solve this kind of situation is to handle folder and file permission separately, with something like:

Clion Git Clone
