-# unitfile-parser
+# systemd-unitfiles
+
+This is a small utility library to parse systemd unitfiles to- and from JavaScript data structures. Three formats are available:
+1. `string`, which is the representation inside a unit file,
+2. `ast`, which is a JS object representation of the parser AST, including comments,
+3. `data`, which is a normalized representation of the data, useful to do general computing. It hast the following format:
+
+```
+{
+  title: String,
+  settings: {
+    [key:String]: String|String[],
+  }
+}[]
+```
+
+Conversions are available in all directions between these formats, with the only external dependency being `chevrotain`.
+
+This package does not know or check whether the logic of a unit file is correct (e.g. are you using the correct names for options, etc.), it only know what the syntax is supposed to be.
+
+## Usage
+
+For most usecases, you'll only need two functions: `stringToData` and `dataToString`:
+
+```
+import { readFile, writeFile } from 'fs/promises';
+import { stringToData, dataToString } from 'systemd-unitfiles';
+
+(async () => {
+  const unitFilePath = '~/.config/systemd/user/xsettingsd.service';
+
+  // Read the current file from disk
+  const fileContents = await readFile(unitFilePath);
+
+  // Transform it to a useful data structure
+  const unit = stringToData(fileContents);
+
+  // Change it around
+  const transformedUnit = doSomeTransformation(unit);
+
+  // Transform the changed unit back to a string
+  const newFileContents = dataToString(transformedUnit);
+
+  // Write the changed file back to disk
+  await writeFile(unitFilePath, newFileContents);
+})();
+```
+
+## API
+
+This package is written for esm5 and above, providing only JS modules (`.mjs` files) to work with.
+
+### stringToAst(input: String): Object
+
+Convert a unit file string to a JS AST.
+
+```
+import { readFile } from 'fs/promises';
+import { stringToAst } from 'systemd-unitfiles';
+
+readFile('~/.config/systemd/user/xsettingsd.service')
+  .then(fileContents => {
+    const ast = stringToAst(fileContents);
+    console.log(ast);
+  });
+
+```
+
+### stringToData(input: String): Array
+
+Convert a unit file string to a normalized representation. This is equivalent to the following:
+
+```
+const data = astToData(stringToAst(string));
+```
+
+### astToData(ast: Object): Array
+
+Convert the parser ast to a normalized representation.
+
+### astToString(ast: Object): String
+
+Convert an ast to a valid unit file string.
+
+```
+import { writeFile } from 'fs/promises';
+import { astToString } from 'systemd-unitfiles';
+
+const ast = // some ast here
+
+const unitFile = astToString(ast);
+
+writeFile('~/.config/systemd/user/xsettingsd.service', unitFile);
+```
+
+### dataToAst(data: Array): Object
+
+Convert the normalized JS representation to the parser ast.
+
+### dataToString(data: Array): String
+
+Convert the normalized JS representation to a valid unit file string. This is equivalent to the following:
+
+```
+const string = astToString(dataToAst(data));
+```
+
+### Lexer 
+
+Constructor for a lexer that extends the [chevrotain Lexer](https://sap.github.io/chevrotain/documentation/7_0_3/classes/lexer.html).
+
+### Parser 
+
+Constructor for a parser that extends the [chevrotain CSTParser](https://sap.github.io/chevrotain/documentation/7_0_3/classes/cstparser.html).
+
+### visitorCreator(parser: Parser): ICSTVisitor
+
+Function that takes a parser and returns a visitor for that parser that would normalize the ast to the abovementioned data format.
+
+## Motivation
+
+There already is a `systemd-unitfile` package on npm, but it is unmaintainted and, especially when going frankly bad. It doesn't support multiline values, it gives a
