# Linux OOM Analyser
|
||||||
|
|
||||||
|
I've started this project to give the Python to JavaScript compiler
|
||||||
|
[Transcrypt](https://www.transcrypt.org/) a try.
|
||||||
|
|
||||||
|
This web page splits the content of a Linux Out Of Memory message into
|
||||||
|
smaller pieces, aggregates these and presents them in a more human friendly
|
||||||
|
format.
|
||||||
|
|
||||||
|
|
||||||
|
## Design Goals
|
||||||
|
* A local copy of the web page should run offline - without an Internet
|
||||||
|
connection, without loading 3rd party libraries nor transferring data to
|
||||||
|
foreign servers
|
||||||
|
* A better understanding of the Linux Memory Management
|
||||||
|
* Start learning JavaScript, CSS and HTML
|
||||||
|
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
* [Python](http://www.python.org) 3.6 or later
|
||||||
|
* [Transcrypt](https://www.transcrypt.org/) 3.6.53 or later
|
||||||
|
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
Install Python virtual environment
|
||||||
|
|
||||||
|
Use the provided Makefile:
|
||||||
|
|
||||||
|
```
|
||||||
|
# make venv
|
||||||
|
```
|
||||||
|
|
||||||
|
or setup the virtual environment manually:
|
||||||
|
|
||||||
|
```
|
||||||
|
# virtualenv env
|
||||||
|
# . env/bin/activate
|
||||||
|
# env/bin/pip install -Ur requirements.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
## Build
|
||||||
|
Use the provided Makefile:
|
||||||
|
```
|
||||||
|
# make venv
|
||||||
|
```
|
||||||
|
|
||||||
|
or build it manually:
|
||||||
|
|
||||||
|
```
|
||||||
|
# . env/bin/activate
|
||||||
|
# transcrypt --build --map --nomin -e 6 OOMAnalyser.py
|
||||||
|
```
|
||||||
|
|
||||||
|
