After a package update, transcrypt produces incomplete JS:
__target__/OOMAnalyser.js (147:15)
145: }
146: if (cols_to_strip) {
147: var line = ;
^
148: }
149: if (line.startswith ('kernel:')) {
instead of
146 if (cols_to_strip) {
147 var line = __getitem__ ((function () {
148 var __accu0__ = line;
149 return __call__ (__accu0__.py_split, __accu0__, ' ', cols_to_strip);
150 }) (), __neg__ (1));
151 }
152 if (line.startswith ('kernel:')) {
A temporary pinning of Transcrypt to Python 3.7 solves this issue.

# OOMAnalyser
|
|
|
|
[](https://builds.sr.ht/~carstengrohmann/OOMAnalyser?)
|
|
|
|
## Introduction
|
|
|
|
OOMAnalyser is a small project to transform the OOM message of a Linux kernel into a more user-friendly format.
|
|
|
|
OOMAnalyser consists of a web page into whose input field the OOM message is copied. JavaScript code extracts the data
|
|
from it and displays the details. All processing takes place in the browser. No data is transferred to external servers.
|
|
This makes it possible to use a locally stored copy of the website for analysis.
|
|
|
|
This project is written in [Python](https://www.python.org) and uses [Transcrypt](https://www.transcrypt.org/) to
|
|
translate Python code into JavaScript.
|
|
|
|
The current online version is available at https://www.carstengrohmann.de/oom/ .
|
|
|
|
|
|
## Installation
|
|
|
|
Installing OOMAnalyser is quite easy since OOMAnalyser consists only of two files, a
|
|
HTML file and a JavaScript file. Both can be stored locally to use OOMAnalyser
|
|
without an Internet connection.
|
|
|
|
### Installation steps
|
|
|
|
1. Open https://www.carstengrohmann.de/oom/ in a browser
|
|
2. Browse down to the paragraph "Local Installation" at the end of the document
|
|
3. Download the HTML file and the JavaScript file to the main directory
|
|
4. Open the file `OOMAnalyser.html` in your favourite browser
|
|
|

|
## Building OOMAnalyser
|
|
|
|
### Requirements
|
|
|
|
* [Python](http://www.python.org) 3.7
|
|
* [Transcrypt](https://www.transcrypt.org/) 3.7
|
|
* [Rollup](https://rollupjs.org/)
|
|
|
|
|
|
### Prepare the build environment
|
|
|
|
* Clone the repository:
|
|
```
|
|
# git clone https://git.sr.ht/~carstengrohmann/OOMAnalyser
|
|
```
|
|
|
|
* Setup the Python virtual environment:
|
|
|
|
```
|
|
# virtualenv env
|
|
# . env/bin/activate
|
|
# env/bin/pip install -Ur requirements.txt
|
|
|
|
or
|
|
|
|
# make venv
|
|
```
|
|
|
|
### Build OOMAnalyser
|
|
|
|
```
|
|
# . env/bin/activate
|
|
# transcrypt --build --map --nomin -e 6 OOMAnalyser.py
|
|
# rollup --format=umd --name OOMAnalyser --file=OOMAnalyser.js -- __target__/OOMAnalyser.js
|
|
|
|
or
|
|
|
|
# make build
|
|
```
|
|
|
|
### Usage
|
|
|
|
* Change into the source directory and start your own small web server.
|
|
|
|
* Start Python built-in web server:
|
|
|
|
```
|
|
# python3 -m http.server 8080 --bind 127.0.0.1
|
|
|
|
or
|
|
|
|
# make websrv
|
|
```
|
|
|
|
* Open the URL http://localhost:8080/OOMAnalyser.html in your favorite browser.
