Bug ID: 372950
Summary: Fortran syntax highlighting: distinguish free format
and fixed format
Product: kate
Version: 16.04
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: syntax
Assignee: kwrite-bugs-n...@kde.org
Reporter: ja...@gcc.gnu.org
Target Milestone: ---
Kate currently seems to have only one syntax-highlighting mode for Fortran.
However, in the Fortran language there are two different source formats:
* fixed format (from the old Fortran77 standard, extension .f)
* free format (introduced with Fortran90, extension .f90)
The keywords etc are the same, but one thing that differs is commenting: In
fixed format every line with a 'c' in the first column is a comment, while in
free format comments start with an '!' (in any column).
Both of these mechanisms seem to be supported in Kate 16.04.3 on Ubuntu 16.10
(with Fortran highlighting file v2). The problem is that lines starting with
'c' are also displayed like a comment in f90 files (where only '!' indicates a
comment).
Simple example ('test.f90'):
! this is a test program that does absolutely nothing
program test
contains
subroutine s
end subroutine
end program
The first line is greyed out, which is correct, but also the third line
('contains') is greyed out, which is wrong. It is displayed normally if a space
is inserted before 'contains.'
