app4triqs

A skeleton for a TRIQS application

Caution: The following instructions require the util-linux rename command. Please confirm that you have the right version by running rename --version. For the Perl rename command see instructions in the following section.

To adapt this skeleton for a new TRIQS application, the following steps are necessary:

• Create a repository, e.g. https://github.com/myuser/mynewapp

• Run the following commands in order after replacing myuser, mynewapp and MYNEWAPP accordingly

github_username=myuser
app_name=mynewapp
capital_name=MYNEWAPP

git clone https://github.com/triqs/app4triqs --branch unstable ${app_name}
cd ${app_name}
git reset $(git commit-tree HEAD\^{tree} -m "Create ${app_name} from github.com/triqs/app4triqs skeleton")
git merge --allow-unrelated-histories -s ours HEAD@{1} -m "Track app4triqs skeleton"
find . -type f | grep -v .git | xargs sed -i 's/app4triqs/${app_name}/g; s/APP4TRIQS/${capital_name}/g'
find . -type d | grep -v .git | xargs rename app4triqs ${app_name}
find . -type f | grep -v .git | xargs rename app4triqs ${app_name}
git add -A && git commit -m "Adjust app4triqs skeleton for ${app_name}"
git remote set-url origin https://github.com/${github_username}/${app_name}
git remote add app4triqs_remote https://github.com/triqs/app4triqs
git remote update && git remote prune origin

You can now push to your github repository

git push origin unstable

Perl rename command

If you are using the Perl-based rename command you will need to

find . -type d | grep -v .git | xargs rename 's/app4triqs/${app_name}/'
find . -type f | grep -v .git | xargs rename 's/app4triqs/${app_name}/'

Github SSH interface

If you prefer to use the SSH interface to the remote repository, replace the http link accordingly

https://github.com/myuser/mynewapp   -->   git@github.com:myuser/mynewapp
