How To Copy The Modified Files from a GitHub Pull Request

Suppose we wanna copy the Modified Files from this PR:

https://github.com/lupyuen2/wip-nuttx/pull/56/files

From this repo:

https://github.com/lupyuen2/wip-nuttx/tree/gpio2

To this repo:

https://github.com/rushabhvg/nuttx/tree/gpio

Here's how:

## Download the Source `gpio2` branch to /tmp/gpio2/nuttx
cd /tmp
mkdir gpio2
cd gpio2
git clone \
  https://github.com/lupyuen2/wip-nuttx \
  nuttx \
  --branch gpio2

## Download the Destination `gpio` branch to /tmp/gpio/nuttx
cd /tmp
mkdir gpio
cd gpio
git clone https://github.com/rushabhvg/nuttx \
  nuttx \
  --branch gpio

To get a list of the Modified Files by PR, we run this:

## Get the Diff Files from the PR
pr=https://github.com/lupyuen2/wip-pinephone-nuttx/pull/56
curl -L $pr.diff \
  | grep "diff --git" \
  | sort \
  | cut -d" " -f3 \
  | cut -c3-

We will see the output:

.gitignore
arch/risc-v/src/bl808/Make.defs
arch/risc-v/src/bl808/bl808_gpio.c
arch/risc-v/src/bl808/bl808_gpio.h
arch/risc-v/src/bl808/hardware/bl808_glb.h
boards/Kconfig
boards/risc-v/bl808/ox64/configs/nsh/defconfig
boards/risc-v/bl808/ox64/include/board.h
boards/risc-v/bl808/ox64/scripts/gnu-elf.ld
boards/risc-v/bl808/ox64/scripts/ld.script
boards/risc-v/bl808/ox64/src/Makefile
boards/risc-v/bl808/ox64/src/bl808_appinit.c
boards/risc-v/bl808/ox64/src/bl808_autoleds.c
boards/risc-v/bl808/ox64/src/bl808_userleds.c

Then we copy and paste into a script like this:

(In VSCode: Use "Right-Click > Change All Occurrences" and change all Line Feeds to copy_file)

## Copy a Diff File
function copy_file {
  set -x  #  Echo commands
  cp \
    /tmp/gpio2/nuttx/$1 \
    /tmp/gpio/nuttx/$1
}

## Copy all Diff Files
copy_file .gitignore
copy_file arch/risc-v/src/bl808/Make.defs
copy_file arch/risc-v/src/bl808/bl808_gpio.c
copy_file arch/risc-v/src/bl808/bl808_gpio.h
copy_file arch/risc-v/src/bl808/hardware/bl808_glb.h
copy_file boards/Kconfig
copy_file boards/risc-v/bl808/ox64/configs/nsh/defconfig
copy_file boards/risc-v/bl808/ox64/include/board.h
copy_file boards/risc-v/bl808/ox64/scripts/gnu-elf.ld
copy_file boards/risc-v/bl808/ox64/scripts/ld.script
copy_file boards/risc-v/bl808/ox64/src/Makefile
copy_file boards/risc-v/bl808/ox64/src/bl808_appinit.c
copy_file boards/risc-v/bl808/ox64/src/bl808_autoleds.c
copy_file boards/risc-v/bl808/ox64/src/bl808_userleds.c

The Modified Files will be copied from /tmp/gpio2/nuttx to /tmp/gpio/nuttx

This is super helpful for splitting a Huge Pull Request like this:

• Apache NuttX RTOS on Sophgo SG2000 / Milk-V Duo S

Into Multiple Smaller Pull Requests:

• arch/risc-v: Add support for SOPHGO SG2000 SoC (T-Head C906)

• boards/risc-v: Add support for Milk-V Duo S SBC (SOPHGO SG2000 SoC)
