Valentin Gagarin db6faf44a9 clarify what store objects can be 
the store of course makes a distinction, but that is not relevant here

Valentin Gagarin c345345dee concept map: align hights 
this has the weird but nice emergent property that terms at the same
height are roughly at the same level of abstraction.
 2022-08-04 12:37:47 +02:00
Valentin Gagarin a28d6878b2 concept map: put closure as it is in the chapter 
this is not as compact any more, but it more closely resembles the
chapter structure, and clearly shows that the closure property is the
key idea on which most of Nix operates.
 2022-08-04 12:37:47 +02:00
Valentin Gagarin 475a332025 make concept map even more compact 2022-08-04 12:37:47 +02:00
Valentin Gagarin d8b2f9f772 make concept map more compact 
invert arrows to/from derivation:
- we need closures to form derivations
- we need derivations to perform builds
 2022-08-04 12:37:47 +02:00
Valentin Gagarin 348432f48f store: add concept map 
this should help nativate the chapter by indicating which terms should

Valentin Gagarin 7c656d90ca simplify description of diagram 
try not to be too fancy, it's just for reading the diagram out loud.
 2022-08-04 12:37:47 +02:00
Valentin Gagarin 631ca18ee6 reword notes on copying 
clarify that we are copying between different stores. we have not
introduced that notion or why it would be interesting, but for now it
should be fine to keep it in context of the store directory.

we could move that later to a more detailed explanation of different
store types.

Valentin Gagarin 7993ba1f38 constrain garbage collection scope 
garbage collection is now incremental, and may (in theory) never delete all unreferenced objects if it is slow enough.
 2022-08-04 12:37:47 +02:00
Valentin Gagarin 195aa28ff7 references are added according to build task 
at this level of abstraction we do not really care about build instructions or what they are, and also build instructions including their arguments really amount to the build task.

Valentin Gagarin 843288a451 add subsections for objects and references 
group description of data instead of spreading it across the section.

that should help direct skimming. as it turns out, people do not
actually read any of that.

Valentin Gagarin b84f2bdfdd introduce mapping to Unix files and processes 2022-08-04 12:37:47 +02:00
Valentin Gagarin 207992a71d introduce store and store objects without file system details 
this leaves open implementation details, especially about store paths
and file system objects, and allows explaining them together were it is
more appropriate. also leaves room to carefully introduce the key
insight behind Nix: applying results from programming language theory to
the operating system paradigm of files and processes.
 2022-08-04 12:37:47 +02:00
Valentin Gagarin e72a7874dc beautify rosetta table 
while this may eventually introduce ugly diffs, the table will now
render readably on the terminal (e.g. for `man nix` or `nix --help`)
without further intervention.

Valentin Gagarin b6b112b366 use reference links for URLs 2022-08-04 12:37:47 +02:00
Valentin Gagarin d5eea66615 introduce build tasks 
while it appears a bit much for the overview, this way we set the stage
for going directly into data types when describing the store, instead of
first having to say what build tasks are and how they relate to build
plans.
 2022-08-04 12:37:47 +02:00
Valentin Gagarin 7c3bca1372 revert to build plans in top-level overview 
do not introduce build tasks yet, that is the next level of detail.

Valentin Gagarin 4639b36b53 use reference links for URLs 2022-08-04 12:37:47 +02:00
Valentin Gagarin 2303f84a68 revert to "build plan" in overview diagram 
this displays correct composition again. build inputs and build results
are not part of build plans in terms of data objects.

also this is a much less complicated setup. this will be the first
impression of architecture, and we want to get it right.

 2022-08-04 12:37:47 +02:00
Valentin Gagarin 0e63b9bf88 add link from overview to store section 
the overview should only link to the three main concepts presented. the
store is now fairly fleshed out. others can follow later.

 2022-08-04 12:37:47 +02:00
Valentin Gagarin 902638c519 build step -> build rule 
"step" sounds atomic, while "rule" hints at internal structure, which in
our case consists of mapping inputs to outputs using build instructions.

Valentin Gagarin 5fda995491 formalize file system objects 
convention: describe every data type in prose, and illustrate with
a class diagram, and a textual representation of an abstract
data type.

right now we save ourselves the trouble of doing class diagrams, we can
add them later. but they are important.
 2022-08-04 12:37:47 +02:00
Valentin Gagarin fb2ec7e4ec reword section on references

Valentin Gagarin 7598126391 remove separate meta-section, add architecture diagram 
the diagram is a first approximation and only covers that same section.
of course there is much more going on, and other features should at some
point also be illustrated.

we also have to think about presentation format and technicalities
behind it. the manual has to render to `man`, but we may want something
more refined for web view.
 2022-08-04 12:37:46 +02:00
Valentin Gagarin 34ea74c9ec reword introductory section 
there should be a meta section for each chapter to give motivation of

 2022-08-04 12:37:46 +02:00
Valentin Gagarin b387d80943 remove sentence for chapter transition 
idea: sections could be read in different orders by linking them in
different ways (e.g. depth-first or breadth-first). adding hard-coded
transitions makes that confusing.

John Ericson 523359d133 WIP: Document the design of Nix 
The current docs are all "how to do things" and no "what is Nix" or "why
are things the way they are".

I see lots of misconception on the wider internet, and I also think we
would benefit from a "living document" to answer some questions people
currently turn to the thesis for.

I think a new section of the manual can address all these issues.

Valentin Gagarin 499ed26508 manual: remove "Writing Nix Expressions" chapter 
it is out of date, all over the place in level of detail, is really

also:
- update redirects and internal links
- use "Nix language" consistently

Respect the outputSpecified attribute 
E.g. 'nix build nixpkgs#libxml2.dev' will build the 'dev' output.

Jan Tojnar 7708a34a51 doc: Add anchors to long lists 
Added using the following sed scripts:

- For command-ref/opt-common.md:

- For expressions/builtin-constants.md:

    s~- `(builtins\.?)([^`]+)`~- [`\1\2`]{#builtins-\2}~g

- For expressions/advanced-attributes.md

    s~^  - `([^`]+)`~  - [`\1`]{#adv-attr-\1}~g

  and manually adjusted outputHashAlgo & outputHashMode.

- For glossary.md

    s~^  - (`([^`]+)`|(.+)) ?\\~  - [\1]{#gloss-\2\3}\\~g;
    s~(gloss-\w+) ~\1-~g

  and manually adjusted anchors for Nix expression, user environment, NAR, ∅ and ε.

- For command-ref/env-common.md

    s~^  - `([^`]+)`~  - [`\1`]{#env-\1}~g'
