-Today I started working on the HTTP server that finds, converts and serves content stored in the (SQL) backend just-in-time (later the server could also cache content).
-
-The server can handle these types of requests:
-
-## Fileder Index Requests
-A request like `GET /path/to/fileder/` (note the trailing slash) is used to query the contents of a fileder.
-It solicits a JSON-encoded response that contains the full paths to all children of this fileder, as well as all facets currently stored, e.g:
-
-    {
-      "children": [
-        "/projects/vcv_mods",
-        "/projects/HowDoIOS",
-        "/projects/iii-telefoni",
-        "/projects/btrktrl",
-        "/projects/demoloops",
-        "/projects/VJmidiKit",
-        "/projects/gayngine",
-        "/projects/themer",
-        "/projects/chimpanzee_bukkaque"
-      ],
-      "facets": [
-        ["", "text/moonscript -> fn -> mmm/dom"],
-        ["name", "alpha"],
-        ["title", "text/plain"]
-      ]
-    }
-
-## Facet Requests
-A request like `GET /path/to/fileder/facet_name` is used to query a facet.
-To differentiate a request for the 'unnamed' facet from an index request, unnamed facets are represented as a `:` character instead.
-The type to ask for can be specified in a `MMM-Accept` header separately, it defaults to `text/html`.
-
-The server either sends back the (possibly converted) facet with a `200 OK` status,
-or a `406 Not Acceptable` error if no conversion was possible.
-
-I also restructured the code a bit and moved some of the HTML-rendering code into the main mmmfs code.
-Then I renamed the `text/html` type to `text/html+frag`, since it refers to only a fragment of HTML code, not a whole document,
-and added a new *convert* from `text/html+frag` to `text/html` that wraps the fragment in the HTML template and style.
-
-the full code change is in commits [81e143f](https://git.s-ol.nu/mmm/commit/81e143fa8181a6adb58d7fba632bd31a13164410/) and [ad26c7c](https://git.s-ol.nu/mmm/commit/ad26c7c4e374f66a978f9946bbb083377f2224a6/)

-Today I mostly fixed the output/rendering of the 'live' server I implemented yesterday.
-
-I changed the URL scheme, it no longer uses headers, which made it hard to link to resources through `<link>` and `<script>` tags.
-Instead the path, facet-name and type are now all part of the URI:
-
-| URI                                            | fileder path       | facet name      | type                           |
-| ---------------------------------------------- | ------------------ | --------------- | ------------------------------ |
-| `/fileder/facet: type/subtype -> wrapped/type` | `/path/to/fileder` | `facet`         | `type/subtype -> wrapped/type` |
-| `/fileder/: some/type`                         | `/fileder`         | (default facet) | `some/type`                    |
-| `/fileder/alternate:`                          | `/fileder`         | `alternate`     | `text/html` (default type)     |
-| `/path`                                        | `/path`            | (default facet) | `text/html` (default type)     |
-| `/`                                            | `/`                | (default facet) | `text/html` (default type)     |
-
-The fileder-index metadata was moved to a `?index` 'pseudofacet' (e.g. `/fileder/?index`).
-
-**EDIT 2019-10-09:**
-> I will take this chance to show and hopefully explain the point of this all again:
-> With the system running it is now possible to demonstrate the type-coercion that powers the system.
->
-> In the system, every piece of data (the *facet*s) is stored together with it's *type*.
-> When requesting data, it can of course be loaded with that *type*, yielding the data unmodified,
-> but it is also possible to demand a different *type* that may be more useful to the receiving application.
->
-> as an example we can take for example this article about one of the internal libraries for writing HTML documents:
-> [`/meta/mmm.dom/`](/meta/mmm.dom/).
->
-> The path `/meta/mmm.dom/` corresponds, according to the table above, to the default facet of the `/meta/mmm.dom` fileder,
-> and since no type was specified, it is assumed that the browser wants a `text/html` document.
-> The follwing path gives the same result, but makes this explicit:  
-> [`/meta/mmm.dom/:text/html`](/meta/mmm.dom/:text/html)
->
-> now, instead of asking for the rendered HTML document, we can also ask for the source, which is of the type
-> `text/moonscript -> mmm/dom` (a Moonscript file that evaluates to a website-fragment):  
-> [`meta/mmm.dom/:text/moonscript -> mmm/dom`](/meta/mmm.dom/:text/moonscript%20-%3E%20mmm/dom)
->
-> the source code was written in MoonScript, which compiles to Lua before it is executed.
-> We can also ask the server to do that for us:
-> `text/lua -> mmm/dom` (a Lua file that evaluates to a website-fragment):  
-> [`meta/mmm.dom/:text/lua -> mmm/dom`](/meta/mmm.dom/:text/lua%20-%3E%20mmm/dom)
->
-> or, we could ask for the generated html fragment, but without the full HTML layout around it -
-> that would be the type `text/html+frag`, as mentioned in the last post:  
-> [`meta/mmm.dom/:text/html+frag`](/meta/mmm.dom/:text/html+frag)
->
-> lastly, we could also ask the system to generate a link to this content, in the `text/html` format (`URL -> text/html`):  
-> [`meta/mmm.dom/:URL -> text/html`](/meta/mmm.dom/:URL%20-%3E%20text/html)  
-> this might seem somewhat redundant, since we need a link to access this link,
-> but it can be useful when a component cannot work with binary data directly, e.g. when mentioning or embedding an image
-> or a video file.
-
-I also added support to the server for serving static assets (e.g. the CSS stylesheet) from the `static` directory.
-These files are accessible through the `/.static/` route (e.g. `/.static/main.css`), where they shouldn't interfere
-with the mmmfs contents.
-With the layout adjsuted to use these new paths, the live server now looks properly styled again too!
-
-Finally I worked on the Dockerfile and my deployment a bit,
-so that my updates to the code will now be automatically applied to my test site,
-which is available at [ba.s-ol.nu](//ba.s-ol.nu) (which might be where you are reading this right now!).

-Today I moved the static resources needed by the web-frontend into the content of the mmmfs itself:
-The server doesn't make an exception for static files anymore (as described in [a previous update][2019-10-08]),
-but rather the files are just in a fileder called `static` now, and properly typed, here:
-
-- [/static/style/](/static/style/:%20text/html+interactive)
-- [/static/mmm/](/static/mmm/:%20text/html+interactive)
-
-This removed a big exception and left the server implementation much cleaner and shorter, as can be seen in the corresponding commit [`005cc9b`][005cc9b].
-
-I also changed the route syntax introduced in [`2019-10-08`][2019-10-08] for getting the fileder index,
-now instead of being hard-coded to return a JSON value at `?index` \[[`b36a1a6`][b36a1a6]\].
-`?index` is treated as a pseudo-facet that can be requested in different types, just like real facets.
-I also added a second pseudo-facet `?tree`, which works like `?index`, except that it recurses and includes
-all content below the current fileder, rather than just including the child-fileders.
-
-Here are some example links for viewing these:
-
-- [`/?index: text/html`](/?index:%20text/html)
-- [`/articles/mmmfs/ba_log/?index: text/html`](/articles/mmmfs/ba_log/?index:%20text/html)
-
-Finally I added a third pseudo-facet called `?interactive` that renders the Inspector that the old page ran on,
-allowing to inspect raw facets, and bringing back the navbar \[[`9ab2f0f`][9ab2f0f]\].
-
-Now that there was a way to serve the Browser to the client again, I got to work on fixing it there.
-This involved a bigger changes in the shared mmm internals:
-
-Up to this point, for each request to render a fileder, the server would load that fileder,
-with all its facets and their values, as well as all children and their facets and children recursively.
-That means that when the root fileder is rendered, currently 120MB of data have to be loaded from disk (or a database).
-Now that the client can render content within the web browser again, that would be even worse due to the network delay.
-
-To solve this, the Fileder implementation now lazy-loads \[[`9632233`][9632233]\].
-When a Fileder is created, it initially knows only its path, but doesn't know which facets or children it contains.
-As soon as that data is attempted to be accessed, the fileder loads in the list of its children and facets from the datastore.
-The facet contents are loaded only when they are actually needed to fulfill a data request or conversion.
-
-With this need for optimization taken care of, I added a new datastore (`web`) \[[`91546d1`][91546d1]\], that can run on the client.
-Instead of directly accessing a database or physical file system, like the `sql` and `fs` stores, the `web` store delegates all
-requests to the server APIs I have been building, such as the new `?index` pseudo-facet.

-Yesterday I got client-side access to the whole mmmfs tree to work via the new `web` datastore,
-but the requests were still extremely inefficient.
-This was because the organisation of the interface between the `Fileder` implementation and the datastore,
-which required the Fileder to make two separate requests to `?index` to fetch its children and facets,
-and also couldn't take advantage of the `?tree` pseudo-facet to bundle together multiple indexes in a single request.
-
-To fix this I added a new datastore method called `get_index` that returns both facet and child information \[[`e2a4257`][e2a4257]\]
-The Fileder implementation now uses this method instead of asking individually for the two pieces of information
-when lazy-loading fileder contents.
-The `get_index` method can also be instructed to recursively load to a fixed depth.
-A Fileder can also be instantiated using such a nested index,
-which causes it to immediately preload up to the same depth without the need for fetching more data.
-This allows some more optimizations, like having the client preload 3-levels deep when it launches,
-which seems like a decent heuristic of the data actually required for most pages and minimizes load time.
-
-I also added some tests for the `Key` class that I use in many different places to represent facet names and types \[[`782d072`][782d072]\]].
-
-The `?interactive` pseudo-facet from yesterday was changed to the `text/html+interactive` type instead \[[`8cdf5d4`][8cdf5d4]\].
-This was a bit of a tough decision, because it is a bit un-idiomatic: rendering the browser page still requires an exception in the browser.
-In the end the motivation for the change was that it should be possible,
-for user ergonomics, to link to the interactive view of a given facet of a given fileder.
-With `?interactive` being a facet, it wasn't possible to specify the facet without jumping out of the adressing system.
-With these updates on the other hand it is possible to link fo example:
-
-- to the main content of the root fileder, as an interactive view: [`/: text/html+interactive`](/:%20text/html+interactive)
-- to the page title of the root fileder, as an interactive view: [`/title: text/html+interactive`](/title:%20text/html+interactive)

-I finally added a better type-conversion-path-finding algorithm \[[`deb21aa`][deb21aa]\].
-The old algorithm only took into consideration how many steps it took to get from type A (stored on disk) to type B (requested).
-This could lead to problems, for example in this situation:
-
-On Disk: `text/moonscript -> fn -> mmm/dom` (a moonscript file that contains a function that returns a bit of UI)  
-Requested: `mmm/dom`  
-Known Conversions:
-1. `text/moonscript` to `mmm/dom` (displays the source code with highlighting)
-2. `text/moonscript -> ???` to `???` (evaluates the moonscript file)
-3. `fn -> ???` to `???` (calls the function, providing access to children and other facets)
-
-Since conversion 1 only takes a single step, it would have been preferred by the old algorithm (although there were workarounds for this).
-The new algorithm adds the concept of conversion-cost, that has to be specified for each conversion.
-The conversions 2 and 3 now have a cost of `1`, while conversion 1 has a cost of `5`.
-The conversions are simply added up and the path with the lowest cost is chosen.
-Like in other pathfinding applications like digital games, the cost metric is also used by the algorithm to enhance the search itself,
-it prioritises searching further on the path with the least current cost.
-
-To implement this optimization I implemented a priority queue:
-
-    -- a priority queue with an index
-    -- only one element with a given key may exist at a time
-    -- when an element with an existing key is added,
-    -- the element with lower priority survives.
-    class Queue
-      new: =>
-        @values = {}
-        @index = {}
-
-      -- add a value with a given priority to the queue
-      -- if no key is specified, assume the element is uniq
-      add: (value, priority, key) =>
-        entry = { :value, :key, :priority }
-
-        if key
-          if old_entry = @index[key]
-            -- already have an entry for this key
-            -- if it is lower priority, we leave it there and do nothing
-            if old_entry.priority < priority
-              return
-
-            -- otherwise we remove the old one and continue as normal
-            -- find the index of the old entry
-            local i
-            for ii, entry in ipairs @values
-              if entry == old_entry
-                i = ii
-                break
-
-            -- remove it
-            table.remove @values, i
-
-          -- store this entry in the index
-          @index[key] = entry
-
-        -- store lowest priority last
-        for i, v in ipairs @values
-          if v.priority < priority
-            -- i is the first key that is lower,
-            -- we want to insert right before it
-            table.insert @values, i, entry
-            return
-
-        -- couldn't find a key with a lower priority,
-        -- so insert at the end
-        table.insert @values, entry
-
-      peek: =>
-        entry = @values[#@values]
-        if entry
-          { :value, :priority, :key } = entry
-          @index[key] = nil if key
-          value, priority
-
-      pop: =>
-        entry = table.remove @values
-        if entry
-          { :value, :priority, :key } = entry
-          @index[key] = nil if key
-          value, priority
-
-      -- iterator, yields (value, priority), low priority first
-      poll: => @.pop, @
-      
-    {
-      :Queue
-    }
-
-This priority queue behaves mostly as expected, but I added an extra feature to make sure that only the
-best conversion path to a specific type is considered for further searching:
-When adding a new element to the Queue, an extra `key` can be passed.
-If a key is passed, the Queue makes sure that there is only ever one element with that key in the queue.
-When a second element would be introduced, the queue discards whichever element has a higher priority value.
-
-This way I can use the type that a conversion path leads to as the key,
-and the queue will automatically discard a worse solution if a better one is found that leads to the same type result.
-
-To make sure the Queue implementation was solid, I also added unit tests for it: [`spec/queue_spec.moon`][spec]

-I'm giving a workshop next weekend, and I had to create the slides for that.
-Since one of the aspirations of `mmmfs` is to be easily adaptable to any kind of data organization and -presentation task,
-that was a good opportunity to try and implement a simple slideshow system.
-
-I started by creating a new fileder to hold the slideshow, [`/articles/xy-workshop`](/articles/xy-workshop/).
-In the main facet, I created a MoonScript file.
-Since the facet needs to access its children (the individual slides), I also used the `fn ->` type,
-that injects the current fileder into the script.
-
-`text/moonscript -> fn -> mmm/dom`
-
-    import ReactiveVar, tohtml, fromhtml, text, elements from require 'mmm.component'
-    import article, button, div, span from elements
-
-    =>
-      index = ReactiveVar 1
-      slide = index\map (index) -> @children[index]
-
-      local view
-      view = div {
-        style: ... -- styling ommited here
-
-        div {
-          style: ... -- styling omitted here
-
-          slide\map => @get 'mmm/dom'
-        }
-      }
-      
-      local left, right
-      if MODE == 'CLIENT'
-        left = (_, e) ->
-          e\preventDefault!
-          index\transform (a) -> math.max 1, a - 1
-
-        right = (_, e) ->
-          e\preventDefault!
-          index\transform (a) -> math.min #@children, a + 1
-
-      tohtml with article!
-        \append div {
-          button '<', onclick: left
-          ' '
-          span index\map (t) -> text t
-          ' '
-          button '>', onclick: right
-        }
-        \append view
-
-I used the `mmm.component` library that lets me create reactive UIs.
-First I declare the reactive variable `index`, the current slide number.
-Then I derive the `slide` reactive variable, that is defined to be the child with index `index` -
-since these are `ReactiveVar`s, whenever `index` changes, `slide` will automatically load the current slide fileder.
-
-Then I create the main slide view, which consists mainly of two containers and some styling.
-Inside, I derive another reactivevar from `slide`: whenever a new `slide` is selected,
-this piece of code will request the main content in `mmm/dom` format and replace the current view content with that.
-
-Lastly I construct a little navigation UI, consisting of the left and right buttons.
-When one of them is clicked, it modifies the `index` variable, making sure to stay in the range of existing slides.
-The rest of the UI then reactively updates accordingly.
-
-Lastly I added keyboard controls for cycling through the slides, as well as a button to enter fullscreen mode.
-You can find the extended code for that in the commit [`ca24ef1`][ca24ef1],
-but it is not a lot either: with the additions the file is 70 lines long.
-
-With this done, it is just a matter of creating children-fileders and placing whichever content I want in them,
-they behave just like any other page of the system now.

-While writing some of the main section of the thesis today,
-I felt the need to illustrate some subject matter with a diagram depicting a folder structure.
-Knowing of some similar tools that generate SVG diagrams from textual descriptions,
-some quick research turned up [mermaid JS][mermaid].
-
-I tried it in their online live editor first to verify that it would indeed do what I needed it to,
-and then added it to the set of supported types in mmm (on the clientside only) \[[`2ff6f90`][2ff6f90]\].
-This was pretty easy in the end, all it took was adding mermaid.js to the interactive version's resources (in `build/server.moon`)
-and then definig the `convert` (and thereby implicitly defining the corresponding type, `text/mermaid-graph`):
-
-    {
-      inp: 'text/mermaid-graph'
-      out: 'mmm/dom'
-      cost: 1
-      transform: (source) =>

-            .innerHTML = svg
-          window.mermaid\render "mermaid-#{id_counter}", source, cb
-    }
-    
-The code is quite short, since all it needs to do is create a container element,
-then tell mermaid.js to render the textual definition.
-Once mermaid.js is done, the rendered content is added in the container element.
-
-Here is one of the two diagrams that I implemented the feature for,
-you can also follow the link through to the source and view the textual representation using the 'inspect' button.

-Besides some smaller fixes with the styling of the page, and in particular the diagrams introduced in [`2019-10-24`][2019-10-24],
-I finally (re-)implemented children-ordering in the `fs`-store of mmmmfs
-(the `sql` store is still missing it, but I am not currently using it either) \[[`a62f63b`][a62f63b]\]:
-Files on the regular filesystem don't have a particular order, but in mmmfs the order of children is is guaranteed,
-so that arranging children in a particular order becomes a meaningful tool.
-
-To store the ordering data, a 'magic' file called `$order` is (optionally) stored in each directory in the filesystem.
-The file lists all child fileders by name in the given order.
-When the children of a fileder are requested (in `list_fileders_in` or `get_index`, which relies on the former),
-all children that are mentioned in `$order` are returned in that order,
-while all remaining children are sorted alphabetically and appended at the end of the list.
-This way the order is guaranteed to be stable even if no `$order` file is specified,
-or when the `$order` file has not been updated after adding new children.
-
-Here is the commented implementation in MoonScript:
-
-      list_fileders_in: (path='') =>
-        -- create a mapping of all child-fileders
-        -- in 'entries' (name -> path)
-        entries = {}
-        for entry_name in lfs.dir @root .. path
-          continue if '.' == entry_name\sub 1, 1
-          entry_path = @root .. "#{path}/#{entry_name}"
-          if 'directory' ~= lfs.attributes entry_path, 'mode'
-            continue
-
-          entries[entry_name] = "#{path}/#{entry_name}"
-
-        -- where we will store our sorted list of children
-        sorted = {}
-
-        -- check for existance of the order file
-        order_file = @root .. "#{path}/$order"
-        if 'file' == lfs.attributes order_file, 'mode'
-          for line in io.lines order_file
-            path = assert entries[line], "entry in $order but not on disk: #{line}"
-            
-            -- add all $order-entries to the sorted output in the same order they appear.
-            -- also flag these entries as already added
-            table.insert sorted, path
-            sorted[line] = true
-
-        -- find the he remaining (non-flagged) entries, sort them alphabetically
-        -- and then append them to the sorted output list
-        entries = [path for entry, path in pairs entries when not sorted[entry]]
-        table.sort entries
-        for path in *entries
-          table.insert sorted, path
-
-        -- return an iterator over the sorted output
-        coroutine.wrap ->
-          for path in *sorted
-            coroutine.yield path
-
-The interface for reordering fileders is still missing in the code,
-and just while writing this I realized that the current implementation is in fact buggy:
-when a fileder that is mentioned in `$order` is deleted via the `stores.fs` API,
-it is not removed from `$order`, causing an error the next time the fileder is listed.
-I will probably get around to fixing both of these problems when I build the corresponding UI.

-Today I finally reached the ability of editing content inside of mmmfs directly!
-
-<mmm-embed path="video" nolink></mmm-embed>
-
-Content is currently not saved anywhere, but the basis of the feature is there.
-For the moment this is implemented as yeat another *convert* that simply converts
-from `text/.*` (any textual code) to `mmm/dom` (web UI) \[[`28653c9`][28653c9]\].
-However this *convert* is only applied in the inspector view (more on that below).
-First, here is the convert itself:
-
-    {
-      inp: 'text/([^ ]*).*'
-      out: 'mmm/dom'
-      cost: 0
-      transform: (value, fileder, key) =>
-        mode = @from\match @convert.inp
-        Editor value, mode, fileder, key
-    }
-
-and the main part of the code, the `Editor` widget:
-
-```moonscript
-class Editor
-  new: (value, mode, @fileder, @key) =>
-    @node = div class: 'editor'
-    -- 'o' is a little helper for converting a Lua table to a JS object
-    @cm = window\CodeMirror @node, o {
-      :value
-      :mode
-      lineNumber: true
-      lineWrapping: true
-      autoRefresh: true
-      theme: 'hybrid'
-    }
-
-    @cm\on 'changes', (_, mirr) ->
-      window\clearTimeout @timeout if @timeout
-      @timeout = window\setTimeout (-> @change!), 300
-
-  change: =>
-    @timeout = nil
-    doc = @cm\getDoc!
-    if @lastState and doc\isClean @lastState
-      -- no changes since last event
-      return
-    
-    @lastState = doc\changeGeneration true
-    value = doc\getValue!
-
-    @fileder.facets[@key] = value
-    BROWSER\refresh!
-```
-
-I chose the [CodeMirror][codemirror] library as the basis for the editor,
-because it seemed like one of the leanest ones I could find
-(and yet it is quite heavy at 100kb plus styling and language support addons).
-The code for the editor is also quite minimale it really just creates a wrapper for the editor
-and tells CodeMirror to set itself up inside.
-Whenever changes are detected, a timeout of 300ms is started,
-after which the preview is refreshed to preview the changes.
-If more changes are made within the 300ms, the timer is reset to 300ms,
-so that the preview update doesn't interrupt the typing flow.
-
-I also spent some time refactoring the global list of converts out into multiple smaller plugins
-(although a lot of global converts remain at the moment) \[[`abefbf8`][abefbf8]\].
-A plugin can export a list of converts as well as a list of 'editors', which are essentially no different,
-except that they are taken into consideration only when converting content for the inspector. 
-
-Breaking the converts up into little packages like that makes it a lot easier to edit,
-and allows enabling and disabling individual features very easily.
-I am also considering moving the converts into the mmmfs data itself,
-to make extending the system and working inside the system more congruent,
-and this is a good way of testing my idea of how the modularization of the system should work.

-Today I implemented updating/saving content in the server, and bridged the feature to the client.
-In the inspector there is now a `save changes` button that (attempts to) save the content on
-the server's filesystem \[[`4b8d9be`][4b8d9be]\].
-
-<mmm-embed path="video" nolink>demonstration of editing and persistantly saving facet</mmm-embed>
-
-Originally I wanted to create a `sandbox` fileder that was to be edited by any one online \[[`d9eafa2`][d9eafa2]\].
-I restricted editing to only fileders underneath `/sandbox`, but then upon publishing quickly realized
-that this left open a major security vulnerability, since content can be evaluated on server or client:
-if a client were to create a facet `exploit: text/lua -> text/plain` with the following content in the root:
-
-```lua
-pass = io.open('/etc/passwd', 'r')
-return pass:read("*all")
-```
-
-...and then request that facet as converted to `text/plain` (`GET /exploit: text/plain`),
-then that Lua code would be executed on the server, and return the confidential `passwd` file on the server.
-This basically meant handing anyone online full unconditionaly access to my server
-(or at least the VM running the website, and potentially options to escalate from there).
-
-As a result I had to choose to either disable public editing, or disable server-side code execution.
-Because server-side execution is a major feature of mmmfs, I settled for the following compromise \[[`1e3b0a1`][1e3b0a1]\]: 
-
-- when developing and running locally, editing and code execution are both enabled in 'unsafe mode'
-- on https://ba.s-ol.nu, editing is disabled but code execution is possible
-- on https://sandbox.s-ol.nu, editing is enabled but code server-side code execution is disabled
-
-The Sandbox can now be found at the following address, at least until the thesis project is concluded:
-
-# [`sandbox.s-ol.nu`](https://sandbox.s-ol.nu)
-
-Currently it is only possible to edit existing facets,
-but creation and deletion of facets and fileders should be implemented soon.

-There was a longer break in development of the projects as I have been focusing on the thesis,
-where progress is not represented accurately in the repository.
-
-There was also some progress on featurse that haven't been tidied up and committed yet,
-such as drag'n'drop / direct file upload. Those features will probably get their own post sometime soon.
-
-Today I spent some time to implement one of the example use-cases that will be part of the theoretical text as well,
-[the 'pinwall' demo][pinwall] \[[`5ec1fe2`][5ec1fe2]\].
-
-The Pinwall example renders all its children as resizeable and movable boxes that can be freely positioned on a canvas:
-
-<mmm-embed nolink path="demo"></mmm-embed>
-
-Any changes to the box positions and sizes are saved persistently as a `pinwall_info` facet on each child.
-For example the size and coordinates of the image can be found at [`image/pinwall_info: text/json`][info].
-
-Rendering the children themselves is pretty easy:
-
-```moon
-import article, div from require 'mmm.dom'
-import convert from require 'mmm.mmmfs.conversion'
-
-update_info = (fileder, x, y, w, h) ->
-  info = (fileder\get 'pinwall_info: table') or x: 100, y: 100, w: 300, h: 300
-  info.x = x if x
-  info.y = y if y
-  info.w = w if w
-  info.h = h if h
-
-  json = convert 'table', 'text/json', info, fileder, 'pinwall_info'
-  fileder\set 'pinwall_info: text/json', json
-  
-=>
-  observe = ... -- (ommited - calls `update_info` when child is resized)
-
-  children = for child in *@children
-      info = (child\get 'pinwall_info: table') or x: 100, y: 100, w: 300, h: 300
-      wrapper = div {
-        style:
-          position: 'absolute'
-          -- (more styling omitted here)
-
-          left: "#{info.x}px"
-          top: "#{info.y}px"
-          width: "#{info.w}px"
-          height: "#{info.h}px"
-
-        -- handle for moving the child
-        div {
-          style:
-            -- (styling omitted here)
-
-          onmousedown: ... -- (omitted)
-        }
-
-        -- child content
-        div {
-          style:
-            width: '100%'
-            height: '100%'
-            background: 'var(--white)'
-
-          (child\gett 'mmm/dom')
-        }
-      }
-      
-      observe wrapper, child
-
-      wrapper
-
-  children.style = {
-    width: '1000px'
-    height: '500px'
-  }
-  
-  children.onmouseup = ... -- (omitted)
-  children.onmousemove = ... -- (omitted)
-  children.onmouseleave = ... -- (omitted)
-  
-  article children
-```
-
-[The rest of the code][source] is just about catching the events when the mouse is clicked/release/moved and when a child is resized,
-and then calling `update_info` as appropriate.

-In the last three days I have been working extensively on support for sidenotes and academic referencing,
-inspired by Edward Tufte's style of publishing (as seen in *Beatiful Evidence* and documented in [tufte-css][tufte-css].
-
-To this end margin-notes have been implemented in the CSS styling of the page using two classes, `sidenote` and
-`sidenote-container`, which are to be applied to individual sidenotes and the containing document respectively.
-Sidenotes are then pulled out of their surrounding context using `position: absolute` and placed in a margin that is
-left free by `sidenote-container`.
-
-Inside of markdown files, sidenotes can then be added simply using basic HTML, like so:
-
-```md
-<div class="sidenote">additional information to be found on the margin</div>
-An example paragraph of text, describing something.
-```
-
-Which will render like this:
-
-> <div class="sidenote">additional information to be found on the margin</div>
-> An example paragraph of text, describing something.
-
-Additionally, conversions from `text/bibtex`, a reference specification format, to `mmm/dom` have been added, that
-create citations using the metadata available in the BibTeX file.
-
-For example the following BibTeX is rendered like this:
-
-<mmm-embed nolink path="../../references/inkandswitch" facet="markdown"></mmm-embed>
-
-> <mmm-embed wrap="raw" path="../../references/inkandswitch"></mmm-embed>
-
-I also added a special override that links to 
-BibTeX files by placing the citation in a sidenote, and adding a footnote indicator in-text.
-
-There is also a handy convert that turns ACM Digital Library links into URLs that directly return the BibTeX file,
-which allows me to cite the links directly without manually adding the BibTeX information to my document.
-
-All of this is implemented in the `cites` plug-in: [`cites.moon`][cites.moon].

-The system described in the thesis and subject to the following blog posts was partially pre-existing to the work
-done as part of the thesis and thesis project. The `mmmfs` system was originally developed as the software for my
-personal website, with development beginning around May 2018. In this phase of development the website and system
-changed shape drastically multiple times.  In the following paragraphs I will describe the state of the project at
-the last revision prior to the beginning of the thesis project, as it existed before the 7th of October 2019.
-All developments since this revision have been tracked in the following project log entries, and are to be considered
-the practical contributions to the thesis project.
-
-In this revision, the system existed as a tool to produce a static website representing the contents of the `mmmfs`
-system in browsable HTML format. The tool had to be run manually after changes, or using a build tool like [`tup`][tup].
-A primitive *Inspector* tab was present in the HTML output and allowed viewing the raw `mmmfs` contents, but all editing
-of content had to be done with external tools and in the external file-system. To see changes in the browser, a
-compilation phase had to be triggered and completed, and consecutively the page reloaded in the browser. There was no
-server-side component that could convert content or store changes for clients. The tool could only accept content from
-the filesystem, not from zip archives or SQLite databases. The conversion algorithm used was more naive and was not
-able to track cost values, which meant that some more advanced conversions couldn't be implemented.
-
-There was already an example implementation of a simple slideshow present, but due to the lack of editing capabilities
-there was no pinwall examle. There was also no support for side- or marginnotes, or academic referencing and citations.
-There also was no support for [`mermaid`][mermaid] diagrams or JSON-encoded data, and there was no plugin interface.
-The HTML template, CSS styling and JS runtime were all built and tracked outside of the `mmmfs` system itself.
-There was no unit tests for any of the project.
