### Separating code into 3 modules (in different files)
Groups can - **if they wish** - modularise their buswire or symbol files into 2 or 3 modules in separate files
1. Symbol1
2. Symbol2
3. Symbol3
With each module referencing the ones before with `open`.
A top-level module `Symbol` or `BusWire` after these three must contain functions exported anywhere outside symbol so that
references in the rest of the code still work.
```
Symbol.fs
let interface1 = Symbol1.interface1
let interface2 = Symbol1.Interface2
let interface3 = Symbol2.interface3
```
### Submodules within one file
Less dramatic, but still useful for modularity. Groups can - **if they wish** - modularise their buswire or symbol files into 3 submodules inside the existing file
```
Symbol.fs
module symbol1 =
let symbol1defn = ...
module symbol2
open symbol1
let symbol2defn
module symbol3 =
open symbol1
open symbol2
let symbol3 defn =
```
Again you will need to mend references - because open Symbol in some other part of Issie would need to become open Symbol.Symbol1, open Symbol.Symbol2 etc to pick up exported code in the submodules. you can add exports to Symbol.fs outside the three submodules as
when each moduel is in separate files.
## Note on assessment
The aim of assessment if that the first two sections should be fairly straightforward and demonstrate basic knowledge
of how to write FP code. They can achieve overall marks up to 70% without extension work. Those working on
significant extensions should put extra effort into these and not complex analysis section since the
analysis marks can accept well-written code supporting extensions as evidence of understanding.
The aim of this is so that you get marks for good code,
if you can write signiifcant good code without being motivated to write reports.
There are signiifcant differences between different code sections, and also things which
change dependning on what your base types are and how ambitious your code rewrite it. Ask early
if you are concerned about how this assessment will impact you. There will be ways to reward code
writing which can be found if need be in individual cases.
## Code Quality ## Code Quality
Things to note:
This will be assessed based on the code. You can **but do not have to** highlight here things you are particularly proud of and want markers to look at (up to 3) as short bullet points:
* Naming of `myGoodName`, `myWonderfulLongName` * Naming of `myGoodName`, `myWonderfulLongName`
* New function boundaries: `topfun` -> `firstfun`, `topfun` -> `secondFun` * New function boundaries: `topfun` -> `firstfun`, `topfun` -> `secondFun`
* New types: MyGoodType * New types: MyGoodType

## Analysis ## Analysis
This combines analysis of **issues in existing code** with **proof or analysis of how/why the new code works**. ### Types
The marking combines both parts. If new code already works and is well written (especially if it is _The types decided in the first part of Symbol.fs were `STransform` of type `Rotation` and `PortOrientationOffset` of type {`PortOrientation`,`Offset`} each with its four possible cases to be used to describe
demonstrated to have significant value in terms of ability to support extensions (see Extensions below) the different rotations fo the symbol and the side of the symbol its ports are at each rotation._
less evidence will be needed for a high mark in this section. _`APortOffsetsMap` of type `Map<string,PortOrientationOffset>` was used to describe the port locations relative to the top left corner of the symbol.
The analysis here demonstrates that you understand the problems in the old code. This map uses string keys `I0..IN` and `O0..ON` to correctly distinguish and store the input and output port offsets in the map._
If the old code has no or few problems you can say this.
Anything you say here may if necessary be tested in the 5 min feedback interview to check understanding. ### Changes to pre-existing code
### Issues in Existing Code
#### Bad Function list Overall small changes were made to the pre-existing code, as the main focus was the correct implementation
of the extensions and symbol enhancements and to ensure their full functionality.
List any problems with the existing code **concisely** as numbered points one function per point. State why Minor changes were made by removing unnecessary parentheses adding comments where necessary and refactoring the code where unnecessary arguments were passed to functions.
the problem exists. List only functions with **significant problems**. You can should refer to XML comments
in your refactored code where this helps. You may note the worst 3 functions even if they have problems that are not
significant.
* if function is poorly documented say why this is necessary (what is not obvious from a good name +
* parameter names + types).
* if function has bad name say why this is confusing
* if a function is poorly written indicate what rewriting would improve this (briefly). You can
refer to your code if this helps.
#### Other problems #### changeLsbf, changeConstantf
Renamed to changeLSBbits and changeConstant respectively to avoid confusion of f being regarded as using an input of type float.
State **concisely** Issues with existing code, or in refactoring for new types, that do not fit into per function list. #### createCustomPortNamesMap
Again numbered points, at most 3. Choose the most inmportant if you have too much to say. You can should Removed parantheses and unnecessary use of input parameter n, as it wasn't used and so that it wasn't required when used.
refer to documentation (not XML docs) in code where this helps.
#### getInputPortsPositionMap, getOutputPortsPositionMap,getPortLocations, getInputPortLocation, getOutputPortLocation
Since getInputPortsPositionMap, getOutputPortsPositionMap are now using getGlobalPortPos which is explained later on in the Extensions section the input parameter of model is not required but only the Symbol list.
Therefore, to avoid confusion and improve readability it was removed as a parameter and as input to the following function addressed above.
Apart from these changes the main focus was targeted at the Extensions of this Section due to their importance.

The code described below are the fully working implemented Symbol - enhancements for the Individual Coding of Section 2 ([Project Spec: Slide 6](https://intranet.ee.ic.ac.uk/t.clarke/hlp/lectures/project22-spec.pdf))

interview. * Show how ports on different symbols are mapped with rotation to the different sides of the symbol.
* Show how the wiring between symbols is also altered with each rotation.
* If code works fully and can be demonstrated in the 5 minute feedback interview no analysis is needed. * Show that the bounding box of each symbol changes with each rotation for each symbol.
* If code will be manually tested in interview say what the tests are that supplement your analysis
* Interview code must be the assessed branch (not something else, or using later group code)
* A good way to show code works is to explain how it differs from existing working code and how existing
functionality is preserved.
# Extensions # Extensions
## 1. Locate port position and orientation, given symbol position and orientation
### Changes in files:
- __Symbol.fs__
- `743-748`canvasPortLocation
- `753-761` getGlobalPortPos
Extensions are required for mark > 70 and optional for mark below 70. High marks on ### Explanation:
the first two sections cannot boost extensions mark if this is lower than them. Functions `canvasPortLocation` and `getGlobalPortPos` were created to produce the "Global" Coordinates of the ports
for each symbol at any given rotation and position. `canvasPortLocation` extracts the `APortOffsetsMap` of the specified
symbol and returns a list of the global XYPos ports of the symbol by combining the offsets with the top-left corner of the symbol.
These coordinates are shown by toggling Developer tools in Issie and are outputted every time a selected symbol is rotated
showing its global coordinates in the order described in Types. Keep in mind the coordinates shown are those before the symbol is rotated.
Similar to `canvasPortLocation`, `getGlobalPortPos` is used to generate the "Global" XYPos of a specified Port on the Canvas
given the port and symbol specified. Since, the `APortOffset` map and `STransform` are part of the Symbol type, the entire symbol is passed to the function,
rather than these separately. After categorizing the port passed to the function as type input or output, the appropriate index of the port is extracted
and is used as a key to extract the correct coordinates of the port to display and to be used by buswire.fs. Since the `APortOffsetMap` is updated
at every rotation (discussed in later extensions), `getGlobalPortPos` will always receive a new `APortOffsetMap` at every orientation and thus
not require the current orientation as input. This can be tested by rotating a symbol and connecting another symbol's ports to its ports.
It can be observed that the gray circles used to distinguish which ports connection can be made are correctly displayed on the rotated symbol, and
the buswire correctly connects to that rotated port location. However, two issues seem to arise. The wire is connected parallel to the
port, if the symbol is rotated as the `buswire.fs` is expecting the symbol to be non-rotated. Additionally, the `buswire.fs` seems to only
update when the symbol is moved. As a result, a communication between the rotations and orientations of the symbol need to be passed
to `buswire.fs` to ensure that the wires are correctly displayed during rotation. This will be done later on in the group work.
$baseMark = \min (70, code * 20/35 + analysis * 15/35)$ ## 2. UI to rotate symbol
### Changes in files:
- __Symbol.fs__
- `1164-1173` RotateSymbols compList
$extendedMark = code * 20/50 + analysis * 15/50 + extensions * 15/50$ - __Sheet.fs__
- `86` Type KeyboardMsg Rotate
$overallMark = \max (baseMark, extendedMark)$ - `859-863` Keypress Rotate
* This section can be missing if you have not done significant extension work.
* Extension code, if well documented (in the code) and clearly written, can be assessed without working
(if it is demonstrated it depends on other people's code not yet written).
* Don't bother writing this section unless you have significant extension work, because the mark here
will usually not be counted in that case (see the marking scheme). Marks for extensions will be awarded
only for work of C level or above.
* delete the above comemnts and add your satement of extensions as below*
1. List as numbered points the extensions (features) your code will support
a. Use nested letters for the functions you have written extra,
or changed, to allow this, and for concise comments concise comments about why they work.
- __Renderer.fs__
- `151-152` makeItem "Rotate Symbol"
### Explanation:
The UI was altered to incorporate the use of symbol rotation. Thus was done by first altering the `Renderer.fs`. Line 151 was added
to add the menu item "Rotate Symbol" in order to be able to rotate any symbol selected. This option was then linked through `Sheet.fs`
This functionality can be found on the menu bar under "View". Further implementation was added to rotation by adding a keyboard shortcut.
This was done in line 86 of `Sheet.fs` where the KeybrdMsg "Rotate" was added to implement this. Lines 859-863 were added to link
the menu item and keyboard shortcut "Shift+R" to Symbol.RotateSymbols in `Symbol.fs` to rotate the symbol selected.
The case "RotateSymbols" was added to the "update" function used in `Symbol.fs` to update the symbols on the canvas. As seen in lines
"1164-1173" a new map of symbols, to be displayed and were existing on the canvas, is created where the symbol with the specified id
found after being seelcted, is changed by incrementing its STransform value to the next Rotation using stransform_fsm and
updating the `APortOffsetMap` using RotatePortMap provided by Section 1. Finally, the model Symbols are replaced by these new symbols.
As a result, the selected symbol is updated with its 90 deg rotated version. Worth noting is the addition of the `canvasPortLocation`
function in this case to print the global port locations as explained previously.
The above can be fully tested by selecting a symbol on the canvas and pressing either `Shift+R` or `View > Rotate Symbol`.
The "Global" port coordinates of the selected symbol will also appear in the console if Developer Tools are toggled on.
### 3. Make symbol bounding box work with rotation
### Changes in files:
- __Symbol.fs__
- `724-727` getBoundingBoxofSymbol
- `728-729` getBoundingBoxes
- `730-731` getOneBoundingBox
### Explanation:
The function `getBoundingBoxofSymbol` was updated to correctly alter the bounding box border of each symbol by taking into account
the current orientation of the symbol. This is done using the STransform passed from the Symbol as input of the function. This is
used as a match case where the bounding box is altered as `HxW` and `WxH` based on the current orientation of the symbol.
The height and weight of the symbol are passed to the border width and height in order or in reverse. This ensures that for every orientation
of the symbol, the correct border is used. The new `getBoundingBoxofSymbol` function is passed to the `getBoundingBoxes` and `getOneBoundingBox`
to be used by `Sheet.fs` to correctly display the Bounding box of the symbol at each orientation.
This can be tested by selecting the symbol to be tested, then rotated and checking with another symbol whether the bounding box
correctly responds when disrupted.
The Symbol enhancements for section 2 described above are fully working without producing any errors during build and runtime
