-# Specification
-
-This specification serves as a starting point to document how `nufmt` should work when formatting nushell scripts. It's meant to be very basic at this point, gradually covering more of the language features.
-
-## Supported Features
-
-### Indentation size
-
-There should be an `--indent` parameter to allow one to specify the number of spaces to use for indentation.
-
-### Indentation
-
-There should be a CRLF and indentation after open braces ()`{`). (TBD - Does this apply to other symbols like `[`, `(`, `|`, etc?)
-
-### Limit the characters per line
-
-There should be a `--limit` parameter to limit to the number of characters per line.
-
-### Number of empty lines before/after custom command
-
-There should be a `--lines-before` and `--lines-after` parameter to set the number of empty lines before and after a custom command.
-
-## Config file
-
-As `rustfmt` does it with a `TOML` file, `nufmt` could have a config file, alongside the command line flags above to set options in stone.
-We have identified the NUON format as a suitable data format for this project: after it's THE data format for `nushell`!
-
-With the values above, it could look something like:
-```nuon
-{
-    CRLF: false,
-    indent: 4,
-    limit: 100,
-    lines: {
-        after: 1,
-        before: 1
-    }
-}
-```
-
-## Sensible (?) default and features
-
-- :one: do not always add newlines when it can help understand the central point of a command call
-```nushell
-http get ({
-    scheme: https,
-    host: api.github.com,
-    path: /users/nushell/repos,
-    params: {
-        sort: updated,
-        per_page: 100
-        page: 1
-    }
-} | url join)
-```
-to put the emphasis on the url structure
-> **Note**  
-> the  `({ ... } | url join)`
-
-- :two: put `|` at the start of the lines for readability, creating a "wall of pipes"
-```nushell
-def "apply to" [
-    file: path
-    modification: closure
-] {
-    $file
-    | path expand
-    | open --raw
-    | from toml
-    | do $modification
-    | save --force $file
-}
-```
-
-- :three: ternary-like conditions when conditions and the two branches are short
-```nushell
-let sign = if $value < 0 { -1 } else { 1 }
-```
-instead of
-```nushell
-let sign = (
-    if $value < 0 {
-        -1
-    } else {
-        1
-    }
-)
-```
-
-- :four: a newline before a block of comments
-```nushell
-some command
-
-# a comment to explain
-another comment
-
-# a block
-# of comment
-# for this
-last command
-```
-
-:five: two spaces before and one space after a comment on the same line as a command
-```nushell
-my-command  # and some explaination
-```
-or in command arguments as well
-```nushell
-def foo [
-    a: int  # my integer argument
-    b: string  # my string integer
-] {}
-```
-
-- :six: 4 spaces as the default indentation
-
-- :seven: remove trailing whitespaces
-
-- :eight: single quotes for single characters and double quotes for strings => that behaviour might change with string interpolation and paths.
-> **Warning**  
-> one should use single quotes (') or backticks (\`) to quote paths on Windows
-
-## Supported Commands
-
-This is the list of the supported commands and their idiomatic formatting. Indentation will be covered by the `--indent` flag but for these examples, 2 spaces will be used.
-
-### if
-
-```bash
-if condition {
-  # some thing
-} else if {
-  # some other thing
-} else {
-  # else the last thing
-}
-```
-
-### for
-
-```bash
-for var in 0..100 {
-  # do something here
-}
-```
