From b8af603d0cd7c1029e21156d91fa411337534245 Mon Sep 17 00:00:00 2001 From: Dag Jomar Mersland Date: Wed, 11 Jun 2025 12:16:31 +0200 Subject: [PATCH] [Cursor] feat: add GitLab MR command to gitstack.sh This commit introduces a new command 'mr' to the gitstack.sh script, allowing users to create GitLab merge requests targeting the correct parent branch. The usage documentation has been updated to reflect this addition. - Added 'mr' command for creating GitLab MRs - Updated usage function to include new command description - Implemented error handling for GitLab CLI availability and stack verification --- bin/gitstack.sh | 99 ++++++++++++++++++++++ bin/gitstack_test.sh | 192 +++++++++++++++++++++++++++++++------------ 2 files changed, 240 insertions(+), 51 deletions(-) diff --git a/bin/gitstack.sh b/bin/gitstack.sh index e369d02..7fd1a82 100755 --- a/bin/gitstack.sh +++ b/bin/gitstack.sh @@ -14,6 +14,7 @@ # gitstack.sh next # <-- checkout next branch in stack (e.g. feature-2 -> feature-3) # gitstack.sh push [stack] # <-- force-push all branches in a stack to remote # gitstack.sh pr [gh-args] # <-- create GitHub PR targeting correct parent branch +# gitstack.sh mr [glab-args] # <-- create GitLab MR targeting correct parent branch # # Description: # create -> Creates a new branch named "-0". @@ -27,6 +28,7 @@ # next -> Checkout next branch in stack (e.g. feature-2 -> feature-3). # push -> Force-push all branches in a stack to remote (uses current stack if none specified). # pr -> Create GitHub PR targeting correct parent branch in stack. +# mr -> Create GitLab MR targeting correct parent branch in stack. # ----------------------------------------------------------------------------- function usage() { @@ -44,6 +46,7 @@ function usage() { echo " $0 next (Checkout next branch in stack)" echo " $0 push [stack] (Force-push all branches in a stack to remote)" echo " $0 pr [gh-args] (Create GitHub PR targeting correct parent branch)" + echo " $0 mr [glab-args] (Create GitLab MR targeting correct parent branch)" echo echo "Commands:" echo " create Creates a new branch named '-0'." @@ -57,6 +60,7 @@ function usage() { echo " next Checkout next branch in stack (e.g. feature-2 -> feature-3)." echo " push Force-push all branches in a stack to remote.
