This way, we can run a -# script and update all of our example documentation output without -# a lot of laborious by-hand checking. -# -# An "SCons example" looks like this, and essentially describes a set of -# input files (program source files as well as SConscript files): -# -# <scons_example name="ex1"> -# <file name="SConstruct" printme="1"> -# env = Environment() -# env.Program('foo') -# </file> -# <file name="foo.c"> -# int main() { printf("foo.c\n"); } -# </file> -# </scons_example> -# -# The <file> contents within the <scons_example> tag will get written -# into a temporary directory whenever example output needs to be -# generated. By default, the <file> contents are not inserted into text -# directly, unless you set the "printme" attribute on one or more files, -# in which case they will get inserted within a <programlisting> tag. -# This makes it easy to define the example at the appropriate -# point in the text where you intend to show the SConstruct file. -# -# Note that you should usually give the <scons_example> a "name" -# attribute so that you can refer to the example configuration later to -# run SCons and generate output. -# -# If you just want to show a file's contents without worry about running -# SCons, there's a shorter <sconstruct> tag: -# -# <sconstruct> -# env = Environment() -# env.Program('foo') -# </sconstruct> -# -# This is essentially equivalent to <scons_example><file printme="1">, -# but it's more straightforward. -# -# SCons output is generated from the following sort of tag: -# -# <scons_output example="ex1" os="posix"> -# <scons_output_command suffix="1">scons -Q foo</scons_output_command> -# <scons_output_command suffix="2">scons -Q foo</scons_output_command> -# </scons_output> -# -# You tell it which example to use with the "example" attribute, and then -# give it a list of <scons_output_command> tags to execute. You can also -# supply an "os" tag, which specifies the type of operating system this -# example is intended to show; if you omit this, default value is "posix". -# -# The generated XML will show the command line (with the appropriate -# command-line prompt for the operating system), execute the command in -# a temporary directory with the example files, capture the standard -# output from SCons, and insert it into the text as appropriate. -# Error output gets passed through to your error output so you -# can see if there are any problems executing the command. -# - -import os -import re -import sys -import time - -sys.path.append(os.path.join(os.getcwd(), 'QMTest')) -sys.path.append(os.path.join(os.getcwd(), 'build', 'QMTest')) - -scons_py = os.path.join('bootstrap', 'src', 'script', 'scons.py') -if not os.path.exists(scons_py): - scons_py = os.path.join('src', 'script', 'scons.py') - -scons_lib_dir = os.path.join(os.getcwd(), 'bootstrap', 'src', 'engine') -if not os.path.exists(scons_lib_dir): - scons_lib_dir = os.path.join(os.getcwd(), 'src', 'engine') - -os.environ['SCONS_LIB_DIR'] = scons_lib_dir - -import TestCmd - - -Prompt = { - 'posix' : '% ', - 'win32' : 'C:\\>' -} - -# The magick SCons hackery that makes this work. -# -# So that our examples can still use the default SConstruct file, we -# actually feed the following into SCons via stdin and then have it -# SConscript() the SConstruct file.
