laj3

Lightweight and smart downloader.

The goal is to recreate how an installer/updater works by only downloading the files that have changed between two updates.

Usage

Server side

You first need to compute the dictionary for your project:

.\laj3.exe dict [-o <output.dict>] [-r] <root>

For example, to add all files in .\myproject\ and its subdirectories:

.\laj3.exe dict -o myproject.dict -r .\test\

You can then start the server:

.\laj3.exe server --port <port> --file <dict>

For example:

.\laj3.exe server --port 8080 --file myproject.dict

Client side

You first need to compute the dictionary for your local files:

.\laj3.exe dict [-o <output.dict>] [-r] [-e] <root>

For example, to create an empty dictionary for the first download:

.\laj3.exe dict -o client.dict -e .

You can then download the sources:

.\laj3.exe install [-f <dict>] <IP:PORT/project>

For example, to download the myproject project sources from 127.0.0.1:8080:

.\laj3.exe install -f client.dict 127.0.0.1:8080/myproject

Notes

• You need to specify <root> when using the dict command with the -e option, but it's not used internally
• You need to use the -f option when using the install command, because laj3 doesn't support on-the-fly dictionary creation yet
• The project path used in the install command has to be specified, but is not yet implemented
