Here follows the list of actions involved in testing a compiler new feature.

The compiler uses the mercurial control revision system. See guide.

# in a debian-based linux distribution
sudo apt-get install mercurial mercurial-common
  • set up the mercurial initial file ".hgrc" with your id
cat <<EOD > ~/.hgrc
[ui]
username = My name <my.account@mail-server.com>
EOD
# set up folders
mkdir -p ~/ur/mercurial-base-folder
mkdir ~/ur/testcompiler

cd ~/ur/mercurial-base-folder

# remove previous checkout if existant
rm -Rf urweb

# Clone the default branch
hg clone http://hg.impredicative.com/urweb

cd urweb

# autoconf to generate the configure file
./autogen.sh

# configure, specifying a destination folder for the compiler
./configure --prefix=$HOME/ur/testcompiler

# edit the sources

# compile, link and install
make && make install
  • test the patched-compiler with a urweb test project
# add the test-compiler to the environment paths head

URW_HOME=$HOME/ur/testcompiler
export PATH=$URW_HOME/bin:$PATH
export LD_LIBRARY_PATH=$URW_HOME/lib/:$LD_LIBRARY_PATH

export LIBRARY_PATH=$URW_HOME/lib/:/usr/local/lib:/usr/lib:/lib
export C_INCLUDE_PATH=$URW_HOME/include

cd ~/my-urweb-project

# This urp directive sets the root url to the main function
# rewrite url My_project/main

urweb my_project
./my_project.exe -p 8082    # a free port_number

# test your project output in the web browser

^C               # stopping the server when done
  • back to the compiler sources
cd ~/ur/mercurial-base-folder/urweb

# check the modified source files
hg status

# add, if necessary, any extra files to mercurial tracking
hg add somefile

# commit the patch
hg commit -m "my patch comment"

# list the patch,
hg log -l5          # list the last n commits -ln

# generate the diff file with the change-set identifiers of your patch, listed by "hg log"
hg export REV1 REV2 > ~/some-folder/my-patch.diff

# attach the exported diff file to a mail-list msg.
