| | | | | | | | | | | | | fixes #4788 fixes #5100 fixes #5108 Tested with the coresponding examples. Now disabling or deleting the symbol_rate block in #4788 correctly updates the depending blocks Signed-off-by: Volker Schroer <3470424+dl1ksv@users.noreply.github.com>
* grc: fix the evaluation of interdependent variablesVolker Schroer2021-08-071-1/+0
| | | | | | | | The gr-digital/examples/tx_ofdm.grc fails to evaluate the header_formater variable. This pr fixes #4937 Signed-off-by: Volker Schroer <3470424+dl1ksv@users.noreply.github.com>
* grc: update disabled blocks if they depend on othersVolker Schroer2021-07-191-1/+2
| | | | | | | | | | | | | | | | | | | | | If we want disabled blocks to be updated properly, we have to consider all blocks when updating the fg not only the enabled. This does the patch of Flowgraph.py and fixes #4788. But a problem remains. If you use the example in #4788 and disable the symbol_rate block, only the samp_rate block 'turns to red'. The other blocks don't change. Only if you open and close an arbitrary block, the other blocks are updated. This is fixed by clearing the namespace in renew_namespace in FlowGraph.py.

* python: Remove unnecessary 'from __future__ import'Oleksandr Kravchuk2020-08-031-1/+0
| | | | | | | | | | | | | | | | All of the removed `from __future__ import` were needed in older versions of Python (mostly 2.5.x and below) but later became mandatory in most versions of Python 3 hence are not necessary anymore. More specifically, according to __future__.py[1]: - unicode_literals is part of Python since versions 2.6.0 and 3.0.0; - print_function is part of Python since versions 2.6.0 and 3.0.0; - absolute_import is part of Python since versions 2.5.0 and 3.0.0; - division is part of Python since versions 2.2.0 and 3.0.0; Get rid of those unnecessary imports to slightly clean up the codebase.

* grc: add python snippets to GRCJosh Morman2020-02-101-0/+41
| | | | | | | | | | | This feature adds the ability to insert arbitrary code into the python flowgraph. It gives a little more low-level flexibility for quickly modifying flowgraphs and adding custom bits of code rather than having to go and edit the generated py file One example is synchronizing multiple USRP objects - sometimes you want different sync than what is offered in the multi-usrp object, so you can put a bit of code in the snippet block to do the custom synchronization

* grc: update namespace properly for nested variablesJosh Morman2019-11-011-2/+2
| | | | | | | | | | | | | | Was getting lots of evaluation error prints when using gr-digital examples because the nested variables were not updated until rewrite() and evaluate were called over and over Seems to fix the issue to update the flowgraph namespace variable after each variable block is evaluated I believe this also alleviates a previous issue (#2634) where rewrite had to be called twice when data was being imported Fixes #2634

* grc: add busports back into 3.8Josh Morman2019-07-151-0/+2
| | | | | | | | Bus ports had not been added back in since the refactor of grc Hopefully this fully enables busports though there are still some issues with the gr-fec flowgraphs Fixes #2277

* grc: Fix Python Module blockHåkon Vågsether2019-01-071-1/+1
| | | | | Before this fix, it was not possible to add a 'Python Module' to a GRC flow graph, it would just throw exceptions when you tried.
* Merge the polished results from the 2017 GSoC "C++ Code Generation with GRC"Andrej Rode2018-12-291-2/+2
|\ | | | | | | | | Flowgraphs with basic blocks can be created in the GNU Radio Companion and exported to a single C++ binary. The use of the C++ generation is still experimental and needs testing and extension to more parts of the GNU Radio codebase.

* | grc: Silence import warnings caused by hier blocks on namespace renewalBrennan Ashton2018-11-281-1/+6
|/ | | | | | | | We do not have a good way right now to determine if an import is for a hier block, these imports will fail as they are not in the search path this is ok behavior, unfortunately we could be hiding other import bugs. Fixes #2183
