x3_fun's Issues

Request: Step by step test driven grammar development example.

I've been trying to work with spirit in a test driven development way, but i am finding it difficult to get any kind of process together. It is difficult to test rules in isolation, or in any structured way.

Can you extend this example to start building a grammar where you start building a an initial base test, and then build the rule to parse it. Then extend the test to another part of the grammar etc.

Examples are outdated, do not build due to API changes in version 1.67.0

From Spirit changelog:

Removed with_context PR#239.

How to add boolean functions and string functions

How can x3_fun be enhanced to handle more complex expressions that contain doubles and their functions along with booleans and bool functions and strings and string functions?

Missing annotations

When reading ast.hpp, I expected operation and expression to be annotated. But when inspecting the values of id_first & id_last, most still equal -1.
It seems that only the outer expression and expressions within parentheses are annotated.

I adapted parse_expression_test.cpp to parse a single expression from command line and put annotated text between brackets.

Here are my results:

$ ./print 2*3
 [2*3] [](2 [] * 3)
$ ./print 1+2*3-4/5
 [1+2*3-4/5]( []1 [] +  [](2 [] * 3) [] -  [](4 [] / 5))
$ ./print (1+2)*(3-4)/5
 [(1+2)*(3-4)/5] []( [1+2]( []1 [] +  []2) [] *  [3-4]( []3 [] -  []4) [] / 5)

Debian/Arch Build/Run instructions

I noticed when we use the standard installed debian/arch boost environments, they have stuff installed in a way that bjam/cmake don't behave as expected when building. In order to circumvent these problems, the easiest way is to ensure you do have boost tools installed, cmake installed, then finally rebuild the latest boost libs from sources yourselves.

apt-get install libboost-tools-dev cmake cmake-curses-gui
pacman -S boost-libs
pacman -S boost-build

cd /usr/local/
wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz/download
tar xvf boost_1_59_0.tar.gz
cd boost_1_59_0/
bjam
export BOOST_ROOT=/usr/local/boost_1_59_0

cd /usr/local/boost_1_59_0/tools/build
./bootstrap.sh
./b2 install --prefix=/usr/local/boost_1_59_0

Add to ~/.bashrc
export BOOST_ROOT=/usr/local/boost_1_59_0
export PATH=$PATH:$BOOST_ROOT/bin
logout and login
