[PATCH 0/9] Add support to develop Git in Visual Studio Code

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-23 13:52:50

[Visual Studio Code](https://code.visualstudio.com/) (nickname "VS Code") is a light-weight, cross-platform, Open Source development environment, with an increasingly powerful extension to support C/C++ development. In particular the intellisense support as well as all the other niceties developers might have come to expect from Integrated Development Environments will help accelerate development.

This topic branch makes it easy to get started using VS Code to develop Git itself.

To get started, run the script `./contrib/vscode/init.sh`. This will initialize the `.vscode/` directory and some files in that directory. After that, simply open Git's top-level directory as "folder" in VS Code.

The files have to be generated because of the curious way Git determines what flags to pass to the C compiler, in particular which constants are defined, because they change the compile flow in rather dramatic ways (determining, e.g. which SHA-1 backend to use).

Johannes Schindelin (9):
  contrib: add a script to initialize VS Code configuration
  vscode: hard-code a couple defines
  cache.h: extract enum declaration from inside a struct declaration
  mingw: define WIN32 explicitly
  vscode: only overwrite C/C++ settings
  vscode: wrap commit messages at column 72 by default
  vscode: use 8-space tabs, no trailing ws, etc for Git's source code
  vscode: add a dictionary for cSpell
  vscode: let cSpell work on commit messages, too

[PATCH 1/9] contrib: add a script to initialize VS Code configuration

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-23 13:52:52

From: Johannes Schindelin <redacted>

VS Code is a lightweight but powerful source code editor which runs on
your desktop and is available for Windows, macOS and Linux. Among other
languages, it has support for C/C++ via an extension.

To start developing Git with VS Code, simply run the Unix shell script
contrib/vscode/init.sh, which creates the configuration files in
.vscode/ that VS Code consumes.

+Configuration for VS Code
+=========================
+
+[VS Code](https://code.visualstudio.com/) is a lightweight but powerful source
+code editor which runs on your desktop and is available for
+[Windows](https://code.visualstudio.com/docs/setup/windows),
+[macOS](https://code.visualstudio.com/docs/setup/mac) and
+[Linux](https://code.visualstudio.com/docs/setup/linux). Among other languages,
+it has [support for C/C++ via an extension](https://github.com/Microsoft/vscode-cpptools).
+
+To start developing Git with VS Code, simply run the Unix shell script called
+`init.sh` in this directory, which creates the configuration files in
+`.vscode/` that VS Code consumes. `init.sh` needs access to `make` and `gcc`,
+so run the script in a Git SDK shell if you are using Windows.

VSCode is an editor.  Is the idea that this will help configure the
editor to do the right thing with whitespace or something?  Or does it
configure IDE features to build git?

Thanks,
Jonathan

To the contrary. This paragraph describes the motivation of the patch.

It is, if you want, the most important part of the entire patch series.

True. Will add a paragraph.

It is a start of all of the above. Ideally, I will be eventually be able
to consistently use VS Code for Git development, whether I have to work on
a Linux, a macOS or a Windows machine.

And I am not happy until the same ease is also available to others. Hence
my contribution.

[PATCH 2/9] vscode: hard-code a couple defines

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-23 13:52:54

From: Johannes Schindelin <redacted>

Sadly, we do not get all of the definitions via ALL_CFLAGS. Some defines
are passed to GCC *only* when compiling specific files, such as git.o.

Let's just hard-code them into the script for the time being.

Could we move these to ALL_CFLAGS?  Is there any downside other than

I assumed that it gives us a bit more liberty at using names for constants
that might otherwise be too general.

I did not even consider the rebuild time, but that's a good point.

The idea to move those definitions to ALL_CFLAGS sounds good to me, yet I
am loathe to introduce this into a patch series that is not about
far-reaching design decisions at all, but merely about making a decent
tool available to the finger tips of all Git contributors.

Read: I think this would make for a pretty good micro-project, maybe in next
year's GSoC (assuming that it happens and that we're accepted again).

While it is technically possible, it is confusing. Not only the user,

[PATCH 5/9] vscode: only overwrite C/C++ settings

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-23 13:52:59

From: Johannes Schindelin <redacted>

The C/C++ settings are special, as they are the only generated VS Code
configurations that *will* change over the course of Git's development,
e.g. when a new constant is defined.

Therefore, let's only update the C/C++ settings, also to prevent user
modifications from being overwritten.

Ideally, we would keep user modifications in the C/C++ settings, but
that would require parsing JSON, a task for which a Unix shell script is
distinctly unsuited. So we write out .new files instead, and warn the
user if they may want to reconcile their changes.

[PATCH 8/9] vscode: add a dictionary for cSpell

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-23 13:53:02

From: Johannes Schindelin <redacted>

The quite useful cSpell extension allows VS Code to have "squiggly"
lines under spelling mistakes. By default, this would add too much
clutter, though, because so much of Git's source code uses words that
would trigger cSpell.

Let's add a few words to make the spell checking more useful by reducing
the number of false positives.

[PATCH 9/9] vscode: let cSpell work on commit messages, too

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-23 13:53:03

From: Johannes Schindelin <redacted>

By default, the cSpell extension ignores all files under .git/. That
includes, unfortunately, COMMIT_EDITMSG, i.e. commit messages. However,
spell checking is *quite* useful when writing commit messages... And
since the user hardly ever opens any file inside .git (apart from commit
messages, the config, and sometimes interactive rebase's todo lists),
there is really not much harm in *not* ignoring .git/.

The default also ignores `node_modules/`, but that does not apply to
Git, so let's skip ignoring that, too.

I am a VS Code user, but I haven't used these settings before.

With these settings, does the editor break lines while I am typing? Or 
does it just insert a visual cue that tells where I should insert a line 
break? If the former, it would basically make the editor unusable for my 
taste. I want to have total control over the code I write. The 80 column 
limit is just a recommendation, not a hard requirement.

Fear not. It is giving you a very clear visual cue, but that's all. It
does show the line wrapped, but the line number column quite clearly shows
that it did not insert a new-line.

Ciao,

[PATCH v2 0/9] Add support to develop Git in Visual Studio Code

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-30 15:42:49

[Visual Studio Code](https://code.visualstudio.com/) (nickname "VS Code") is a light-weight, cross-platform, Open Source development environment, with an increasingly powerful extension to support C/C++ development. In particular the intellisense support as well as all the other niceties developers might have come to expect from Integrated Development Environments will help accelerate development.

Due to the way Git's source code and build process is structured, it can be quite challenging to use VS Code effectively for developing Git. Which is a shame, as developing with vim and the command-line causes unnecessary churn, and it is quite understandable that most Git developers simply do not want to fight with a modern development environment just to try whether they like developing Git with it.

This topic branch makes it easy to get started using VS Code to develop Git.

Simply run the script `./contrib/vscode/init.sh`. This will initialize the `.vscode/` directory and some files in that directory. After that, just open Git's top-level directory as "folder" in VS Code.

The files have to be generated because of the curious way Git determines what flags to pass to the C compiler, in particular which constants are defined, because they change the compile flow in rather dramatic ways (determining, e.g. which SHA-1 backend to use).

Changes since v1:

- Clarified commit message of the first commit.

[PATCH v2 2/9] vscode: hard-code a couple defines

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-30 15:42:52

From: Johannes Schindelin <redacted>

Sadly, we do not get all of the definitions via ALL_CFLAGS. Some defines
are passed to GCC *only* when compiling specific files, such as git.o.

Let's just hard-code them into the script for the time being.

your desktop and is available for Windows, macOS and Linux. Among other
languages, it has support for C/C++ via an extension, which offers to
not only build and debug the code, but also Intellisense, i.e.
code-aware completion and similar niceties.

This patch adds a script that helps set up the environment to work
effectively with VS Code: simply run the Unix shell script
contrib/vscode/init.sh, which creates the relevant files, and open the
top level folder of Git's source code in VS Code.

+Configuration for VS Code
+=========================
+
+[VS Code](https://code.visualstudio.com/) is a lightweight but powerful source
+code editor which runs on your desktop and is available for
+[Windows](https://code.visualstudio.com/docs/setup/windows),
+[macOS](https://code.visualstudio.com/docs/setup/mac) and
+[Linux](https://code.visualstudio.com/docs/setup/linux). Among other languages,
+it has [support for C/C++ via an extension](https://github.com/Microsoft/vscode-cpptools).
+
+To start developing Git with VS Code, simply run the Unix shell script called
+`init.sh` in this directory, which creates the configuration files in
+`.vscode/` that VS Code consumes. `init.sh` needs access to `make` and `gcc`,
+so run the script in a Git SDK shell if you are using Windows.

[PATCH v2 5/9] vscode: only overwrite C/C++ settings

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-30 15:42:56

From: Johannes Schindelin <redacted>

The C/C++ settings are special, as they are the only generated VS Code
configurations that *will* change over the course of Git's development,
e.g. when a new constant is defined.

Therefore, let's only update the C/C++ settings, also to prevent user
modifications from being overwritten.

Ideally, we would keep user modifications in the C/C++ settings, but
that would require parsing JSON, a task for which a Unix shell script is
distinctly unsuited. So we write out .new files instead, and warn the
user if they may want to reconcile their changes.

[PATCH v2 6/9] vscode: wrap commit messages at column 72 by default

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-30 15:42:56

From: Johannes Schindelin <redacted>

When configuring VS Code as core.editor (via `code --wait`), we really
want to adhere to the Git conventions of wrapping commit messages.

[PATCH v2 4/9] mingw: define WIN32 explicitly

This helps VS Code's intellisense to figure out that we want to include

as Windows Vista/2008R2.

[PATCH v2 8/9] vscode: add a dictionary for cSpell

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-30 15:43:00

From: Johannes Schindelin <redacted>

The quite useful cSpell extension allows VS Code to have "squiggly"
lines under spelling mistakes. By default, this would add too much
clutter, though, because so much of Git's source code uses words that
would trigger cSpell.

Let's add a few words to make the spell checking more useful by reducing
the number of false positives.

[PATCH v2 9/9] vscode: let cSpell work on commit messages, too

From: Johannes Schindelin via GitGitGadget <hidden>
Date: 2018-07-30 15:43:01

From: Johannes Schindelin <redacted>

By default, the cSpell extension ignores all files under .git/. That
includes, unfortunately, COMMIT_EDITMSG, i.e. commit messages. However,
spell checking is *quite* useful when writing commit messages... And
since the user hardly ever opens any file inside .git (apart from commit
messages, the config, and sometimes interactive rebase's todo lists),
there is really not much harm in *not* ignoring .git/.

The default also ignores `node_modules/`, but that does not apply to
Git, so let's skip ignoring that, too.
