+# EditorConfig
+
+This plugin implements the [EditorConfig](https://editorconfig.org/) spec
+purely on lua by leveraging lua patterns and the regex engine on lite-xl.
+Installing additional dependencies is not required.
+
+The EditorConfig spec was implemented as best understood,
+if you find any bugs please report them on this repository
+[issue tracker](https://github.com/lite-xl/lite-xl-plugins/issues).
+
+## Implemented Features
+
+Global options:
+
+* root - prevents upward searching of .editorconfig files
+
+Applied to documents indent info:
+
+* indent_style
+* indent_size
+* tab_width
+
+Applied on document save:
+
+* end_of_line - if set to `cr` it is ignored
+* trim_trailing_whitespace
+* insert_final_newline boolean
+
+## Not implemented
+
+* charset - this feature would need the encoding
+  [PR](https://github.com/lite-xl/lite-xl/pull/1161) or
+  [plugin](https://github.com/jgmdev/lite-xl-encoding)
+
+## Extras
+
+* Supports multiple project directories
+* Implements hot reloading, so modifying an .editorconfig file from within
+  the editor will re-apply all rules to currently opened files.
+
+## Testing
+
+This plugin includes a test suite to check how well the .editorconfig parser
+is working.
+
+The [editorconfig-core-test](https://github.com/editorconfig/editorconfig-core-test)
+glob, parser and properties cmake tests where ported and we are getting a 100%
+pass rate.
+
+If you are interested in running the test suite, from the terminal execute
+the following:
+
+```sh
+lite-xl test editorconfig
+```
+
+To inspect the generated sections and regex rules:
+
+```sh
+lite-xl test editorconfig --parsers
+```

+# Profiler Plugin
+
+Profiling is mainly the runtime analysis of a program performance by counting
+the calls and duration for the various routines executed thru the lifecycle
+of the application. For more information view the [wikipedia] article.
+
+This plugin adds the ability to profile function calls while running Lite XL,
+becoming easier to investigate performance related issues and pinpoint what
+could be causing them. It integrates the [lua-profiler] which provides
+the functionality we need.
+
+## Usage
+
+Open Lite XL and access the command palette by pressing `ctrl+shift+p` and
+search for `profiler`. The command `Profiler: Toggle` will be shown to let you
+start or stop the profiler. You should start the profiler before triggering
+the events that are causing any performance issues.
+
+![command](https://user-images.githubusercontent.com/1702572/202113672-6ba593d9-03be-4462-9e82-e3339cf2722f.png)
+
+> **Note:** Starting the profiler will make the editor slower since it is
+> now accumulating metrics about every function call. Do not worry, this is
+> expected and shouldn't affect the end result, just be patience because
+> everything will be slower.
+
+There may be some situations when you would like to enable the profiler
+early on the startup process so we provided a configuration option for that.
+Also the profiler output is saved to a log file for easy sharing, its default
+path is also configurable as shown below:
+
+![settings](https://user-images.githubusercontent.com/1702572/202113713-7e932b4f-3283-42e6-af92-a1aa9ad09bde.png)
+
+> **Note:** since the profiler is not part of the core, but a plugin, it will
+> only start accumulating metrics once the plugin is loaded. The `priority`
+> tag of the profiler plugin was set to `0` to make it one of the first
+> plugins to start.
+
+Once you have profiled enough you can execute the `Profiler: Toggle` command
+to stop it, the log will be automatically open with the collected metrics
+as shown below:
+
+![metrics](https://user-images.githubusercontent.com/1702572/202113736-ef8d550c-130e-4372-b66c-694ee5f4c5c0.png)
+
+You can send Lite XL developers the output of `profiler.log` so it can be
+more easily diagnosed what could be causing any issue.

+@title lua-profiler
+@version 1.1
+@description Code profiling for Lua based code;
+The output is a report file (text) and optionally to a console or other logger.
+
+The initial reason for this project was to reduce  misinterpretations of code profiling
+caused by the lengthy measurement time of the 'ProFi' profiler v1.3;
+and then to remove the self-profiler functions from the output report.
+
+The profiler code has been substantially rewritten to remove dependence to the 'OO'
+class definitions, and repetitions in code;
+thus this profiler has a smaller code footprint and reduced execution time up to ~900% faster.
+
+The second purpose was to allow slight customisation of the output report,
+which I have parametrised the output report and rewritten.
+
+Caveats: I didn't include an 'inspection' function that ProFi had, also the RAM
+output is gone. Please configure the profiler output in top of the code, particularly the
+location of the profiler source file (if not in the 'main' root source directory).
