# Muon Week 2018 - MRRTF Status
##
### Laurent Aphecetche
#### 01 Mar 2018
## <i class="fa fa-plus" aria-hidden=true></i> Things are starting to move
### we are getting more comfortable with "new" software engineering technologies
- Continuous Integration (CI)
- Git Pull Requests (PR)
- CMake
- Boost Test
- Google Benchmark
- Modern C++
---
## <i class="fa fa-minus" aria-hidden=true></i> Still kind of slowly though
### New rules to learn ...
### New rules to discuss ;-)
---
## (Pieces of) Reconstruction
### 1st versions in [AliceO2 repo](https://github.com/aliceo2group/aliceo2)
- mch preclustering <i class="fa fa-check" aria-hidden-true></i>
- mch mapping (segmentation) [PR 866](https://github.com/AliceO2Group/AliceO2/pull/886)
- mid clustering PR soon
---
## (Pieces of) Simulation
- mch geometry porting : work started
---
## Still a long way to go
## ... if we compare to the <a href="https://alice.its.cern.ch/jira/secure/RapidBoard.jspa?rapidView=242&projectKey=MRRTF&view=planning.nodetail">work plan</a>
---
---
## A sample of work "done" :
## MCH mapping redux
---
## Self-contained Mapping
### No more OCDB (or ASCII) files to be loaded.
### You load the library, you get the mapping.
```c++
int detElemId{100}; bool isBendingPlane{true};
o2::mch::mapping::Segmentation seg{detElemId, isBendingPlane};
double x{1.5}; double y{18.6};
int paduid = seg.findPadByPosition(x, y);
if (seg.isValid(paduid)) {
std::cout << "There is a pad at position " << x << "," << y << "\n"
<< " which belongs to dualSampa " << seg.padDualSampaId(paduid)
<< " and has a x-size of " << seg.padSizeX(paduid) << " cm\n";
}
assert(paduid == seg.findPadByFEE(76, 9));
```
---
## Collateral Improvements
- Debugging the mapping requires some sort of visualisation
- Used a web techno : SVGs
- A first step toward mchview-in-a-browser
---
````bash
> mch-mapping-svg-segmentation3 --help
Generic options:
--help produce help message
--hidepads hide pad outlines
--hidedualsampas hide dualsampa outlines
--hidedes hide detection element outline
--hidepadchannels hide pad channel numbering
--de arg which detection element to consider
--prefix arg (=seg) prefix used for outfile filename(s)
--point arg points to show
--all use all detection elements

```

- A SVG is a web document.
- Can be styled using CSS.
- Rendered by the browser. No rendering code to write !
