What is Liquidsoap?

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own

The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.

What is ralger?

ralger stopped scraping only web pages and started scraping the files on them.

ralger is a scraping package that wraps rvest behind task-named functions — titles_scrap(), table_scrap(), images_scrap() and so on — aimed at users who want data out of a page without writing selector logic. After four years of quiet it returned in 2.3.0 with a different kind of function: readers for PDF, XLS, XLSX and CSV files, plus comment extraction.

L6.3

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own

◆ Current state

The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.

◆ Where it's heading

Liquidsoap is expanding on two axes at once. It is broadening what a stream can carry - subtitles are a third content modality in a system that has understood two - and it is moving up the stack from a source that feeds Icecast into something that can be the Icecast. The language work points the same way: a source(_) type for unknown content, callback release semantics, and effect-scoped clocks are the kind of changes made when scripts are getting large enough that lifetime and typing errors cost real production time.

◆ Prediction

The 2.5.0 final should follow the rolling branch within a release cycle, and the migration guide already shipped for the composition parameter changes suggests the breaking surface is considered settled. Watch whether subtitle support reaches the harbor and Icecast server paths, which the current notes do not say.

ralger stopped scraping only web pages and started scraping the files on them.

◆ Current state

ralger is a scraping package that wraps rvest behind task-named functions — titles_scrap(), table_scrap(), images_scrap() and so on — aimed at users who want data out of a page without writing selector logic. After four years of quiet it returned in 2.3.0 with a different kind of function: readers for PDF, XLS, XLSX and CSV files, plus comment extraction.

◆ Where it's heading

The earlier arc was about making HTML scraping survive contact with the real web — wrapping every function in tryCatch so a dead link or missing connection returns NA with a message rather than an error, adding case-sensitivity control, widening heading extraction to h3. The 2.3.0 additions change the target rather than the robustness: the unit of interest becomes the document a page links to, not the page itself.

◆ Prediction

If the file readers follow the pattern the image functions set, expect preview-and-batch companions next — images_scrap() arrived alongside images_preview() for exactly that reason. The four-year gap before this release makes timing unpredictable.
