From 4a6018c5fe6e2bdb67b44b5d4acc03e4c672f374 Mon Sep 17 00:00:00 2001 From: Dylan Baker Date: Wed, 19 Nov 2014 14:15:04 -0800 Subject: glapi: gl_table.py: Use mako to generate the glapitable.h This uses a very simple mako template and a couple of generators to create the gl_table.h file, as opposed to a complex class of print statements. The result is easier to read, and easier to modify. There are a few minor differences between the file generated after this patch and before. 1) The formatting of the copyright is slightly different: lines are wrapped in slightly different places, and the explicit names of the authors and/or copyright holders in the final clause are replaced with "THE AUTHORS OR COPYRIGHT HOLDERS" 2) The "DO NOT EDIT" comment is slightly reworded 3) Some ifdef changes. Each level of preprocessor macro now has one additional space between the # and the first letter of the word, and some comments were removed because the brevity of the template makes it obvious which ifdefs and endifs go together. --- src/mapi/glapi/gen/gl_table.py | 73 ++++++++------------------ src/mapi/glapi/gen/templates/glapitable.h.mako | 73 ++++++++++++++++++++++++++ 2 files changed, 96 insertions(+), 50 deletions(-) create mode 100644 src/mapi/glapi/gen/templates/glapitable.h.mako diff --git a/src/mapi/glapi/gen/gl_table.py b/src/mapi/glapi/gen/gl_table.py index 99403214ac..0b7decf75d 100644 --- a/src/mapi/glapi/gen/gl_table.py +++ b/src/mapi/glapi/gen/gl_table.py @@ -26,55 +26,15 @@ # Authors: # Ian Romanick +import sys import argparse +from mako.template import Template + import gl_XML import license -class PrintGlTable(gl_XML.gl_print_base): -
