history

Project history and usage

saldl is a multi-platform command-line downloader that divides files into chunks and retrieves them concurrently through libcurl. It emphasizes speed, resumability, and early access to selected portions of a download.

Project history

Mohammad AlSaleh created saldl as a libcurl-based downloader optimized for speed and early preview. Copyright notices in the official manual date the project to 2014–2015, while the published manual was updated in 2018.

The project was designed for POSIX systems but its official build notes also cover macOS, MSYS2/Cygwin, and experimental native Windows builds.

Adoption history

The official repository documents Homebrew installation on macOS, AUR packaging, POSIX source builds, and experimental Windows binaries. The supplied input also records Nix packaging.

How it is used

A user supplies a URL and optionally selects chunk size, connection count, output path, resume behavior, or chunk ordering. saldl records partial data and progress in `.part.sal`, `.ctrl.sal`, and `.tmp.sal` artifacts; it can also stream to stdout or use memory buffers.

Why package nerds care

saldl is interesting to package enthusiasts as a compact, cross-platform download accelerator built from established C networking libraries. Its resumable control files, concurrent chunk scheduling, and early-preview ordering expose implementation details that simpler download clients hide.

Timeline

Related projects

saldl builds on libcurl and libevent. Its official repository also includes FlashGot integration, connecting it with browser-driven download workflows.
