Breakpoints are source code markers that let you suspend program execution at a specific point and examine its behavior.
Once set, a breakpoint remains in your project until you remove it explicitly (except for temporary line breakpoints).
If a file with breakpoints was modified externally, for example, updated through a VCS or changed in an external editor, and the line numbers have changed, breakpoints will be moved accordingly. Note that DataGrip must be running when such changes are made, otherwise they will pass unnoticed.
Line breakpoints can be set on executable lines of code. Thread execution is suspended before the line with such breakpoint, and DataGrip displays the stack frames on that thread's stack.
Set a line breakpoint
Place the caret at an executable line of code where you want to gutterpoint and click the gutter next to that line or press Ctrl+F8.
To set a temporary line breakpoint, press Ctrl+Alt+Shift+F8. The breakpoint will be removed from your project right after it is hit.
Remove a line breakpoint
Click the breakpoint icon in the gutter.
To avoid accidentally removing a breakpoint and losing its parameters, you can choose to remove breakpoints by dragging them to the editor, or by clicking the middle mouse button: open the Settings/Preferences dialog Ctrl+Alt+S, go to , and select Drag to the editor or click with middle mouse button. Clicking a breakpoint will then toggle its state (enabled/disabled).
- Quick access to most common settings
Right-click a breakpoint in the editor gutter to quickly disable or suspend it, or set a condition.
- Breakpoints intentions
You can get access to the most common breakpoint actions and filters through intention actions(Alt+Enter).
When a breakpoint is hit, more intention actions are available.
- Group breakpoints
You can organize breakpoints into groups, for example, if you need to mark out breakpoints for a specific problem.
In the Breakpoints dialog Ctrl+Shift+F8, select a breakpoint you want to place in a group and choose from the context menu.
- Move breakpoints
To move a line breakpoint, drag it to the target line.
- Copy breakpoints
To copy a breakpoint, press Ctrl and drag it to the target line.
- Disable breakpoints
To temporarily disable a breakpoint without removing it from the project, hold down the Alt key and click the breakpoint icon in gutter.
- Quick search
If you have many breakpoints in your project, you can add short descriptions to them to search for them easily: right-click a breakpoint in the Breakpoints dialog Ctrl+Shift+F8 and select Edit description from the context menu. Now when you start typing a breakpoint's name, it gets the focus.
- Jump to source
To jump from the Breakpoints dialog to the line of code where the selected breakpoint is set, press F4.
