Screenshots of Photran
At the center of the window is our syntax-highlighting Fortran editor. The Outline view on the right summarizes the high-level constructs in the file. The Problems view allows instant navigation to sites where errors occurred.
By building on the CDT, Photran is able to provide a GUI interface to gdb. The teal dots in the editor indicate breakpoints; the blue arrow identifies the current line while stepping through a subprogram. The Variables view allows the programmer to browse the values of variables visible at the current execution point.
