Repo template #

I wanna make a theme notetheme2 based on dinhanhthi.com.

1. Make dinhanhthi.com be a template (Go to Settings)

2. Create a new repo based on this template.

3. Create a new branch notetheme2 on dinhanhthi.com. Make changes on this branch.

4. Everything we have a "theme change" on dinhanhthi.com/master, merge it to branch dinhanhthi.com/notetheme2.

5. If there are files (only for files) in dinhanhthi.com/notetheme2 you wanna keep, add below line to .gitattributes (under branch dinhanhthi.com/notetheme2) before performing the merge,

   # add line to .gitattributes
   echo 'file_name.txt merge=ours' >> .gitattributes
   # on windows, remove `''`

6. If there are folders (or files) in dinhanhthi.com/notetheme2 you don't wanna keep (from /master), just delete them and make a new commit. From this time, later merges will ignore them.

7. If there are folders in /notethem2 you wanna keep the current state (instead of merging from master), create a script reset_folders.sh

   #!/bin/sh
   # used for branch notetheme2 only
   echo 'Reset some only-this-branch folders after merging.'
   git reset folder_1 folder_2
   git checkout .
   git add .
   git commit -m "update from master"

   Each time you run the merge, run

   git merge master && sh reset_folders.sh

8. Update changes from dinhanhthi.com/notetheme2 to repo notetheme2^[ref].

   # add dinhanhthi.com as a remote
   git remote add template [URL of the template repo]

   # update the changes
   git fetch --all

   # update from template's branch
   git merge template/notetheme2

9. If there is an error fatal: refusing to merge unrelated histories, try to add --allow-unrelated-histories. There must be conflict.

   # keep remotes
   git merge -X theirs template/notetheme2 --allow-unrelated-histories
   # keep local
   git merge -X ours template/notetheme2 --allow-unrelated-histories
