Hi everyone, gr_modtool.py has undergone some heavy revision recently. It'll now do even more stuff:
* It's been changed to the CMake version. The autotools version still
exists on the CGRAN SVN server.
* You can create out-of-tree modules using 'gr_modtool.py create'.
This is basically an improved version of create-out-of-tree-module,
because
- it uses the CMake stuff :) and
- it doesn't give you the square_ff files which you have to remove.
* Of course, there's been bugfixes... and probably new bugs.
All you need to do is download the gr_modtool.py file and copy it
somewhere into your PATH. Then you can create new modules and add code
to it within seconds.
Example: you want to create a new module called 'mydsp' and add two
blocks 'mydsp_algorithm1_ff' and 'mydsp_algorithm2_cc'. The first one is
a sync block, the second a hier block. Also, you'd like bindings for
GRC. This is what it might look like:
% gr_modtool.py create mydsp
Module directory is "./gr-mydsp".
Creating directory...
Copying howto example...
Unpacking...
Replacing occurences of 'howto' to 'mydsp'...
Done.
Use 'gr_modtool add' to add a new block to this currently empty module.
~/tmp % gr_modtool.py add -t sync mydsp_algorithm1_ff
No GNU Radio module found in the given directory. Quitting.
% cd gr-mydsp
:(
% gr_modtool.py add -t sync mydsp_algorithm1_ff
Operating in directory .

Takes 5 seconds. All you need to do is edit the important bits of your
files.
Hope this helps people. Have a nice weekend,
