Lataa arf console 0.4.5

Release Notes
Added
- ARF_R_HOME and ARF_R_VERSION can now select the R installation through environment variables (#271).
- --with-r-version and :switch now accept version ranges (^4.4, ~4.4, >=4.3, <5.0, *) in addition to exact and partial version numbers such as 4.4.2 and 4.4 (#271). Range operators come from the convention Cargo and npm use; R's own version numbers are plain major.minor.patch releases, so prerelease identifiers and build metadata are rejected.
- Experimental: arf can now read the R version a project has pinned and start that version instead of the configured default (#271, #288).
It is opt-in through experimental.r_source_overrides in the arf.toml config.
For example, the following configuration looks for two TOML files named rproject.toml and rproj.toml in the current directory, in order:
[experimental]
r_source_overrides = [
{ type = "toml-key", file = "rproject.toml", key = "project.r_version" },
{ type = "toml-key", file = "rproj.toml", key = "r.version" },
]
If arf finds an R version defined in one of these files, it will select a matching version from the list of versions installed by rig and start that R.
If none of them yields a matching version, arf falls back to the R selected by startup.r_source.
The first of the two, rproject.toml, is used by rv.
It looks like this:
[project]
r_version = "4.4"
The second, rproj.toml, is a draft proposal from Tidyup 9.
Unlike rv's rproject.toml, it also supports Cargo-style version ranges:
[r]
version = ">= 4.1.0, < 4.5.0"
For now, it seems neither of these formats is widely adopted, so arf introduces a generic toml-key type that allows us to specify the filename and key path and supports Cargo-style version ranges.
Of course, we can also support other TOML files with different names and keys for specifying the R version.
- Experimental: arf ipc list now reports a session_type field ("headless" or "interactive") for each session, so external clients can tell an agent-started headless session from an interactive REPL a person is using before sending it a shutdown. Sessions started by an older arf report null, which clients should treat as unknown (#283).
- Experimental: arf ipc session, arf ipc list, and arf headless --json now report r_home, the R installation the session is using, so an editor can use the same R instead of discovering one for itself. Sessions started by an older arf omit it, which clients should treat as unknown (#294).
- Experimental: arf r resolve lets external tools such as editors learn which R arf would use without starting R. It always emits JSON on success (#290, #291, #293).
Changed
- Partial version numbers passed to --with-r-version and :switch (e.g. 4.4) now match only that release series (4.4.x) instead of any version starting with the same text (#271).
Fixed
- arf could fail to start a different R version when R_HOME was set in the environment to point at another R installation (#295).
- Switching R versions with :switch no longer leaves stale .libPaths() entries from the previous R version, including after a :restart. R-related variables you set before starting arf are kept, apart from R_HOME and LD_LIBRARY_PATH, which are always removed. :restart still leaves the environment untouched (#295).
- Flags placed before a subcommand no longer get silently ignored; arf now reports the error and explains where the flag belongs (#275).
- Experimental: Commands sent with arf ipc send are now recorded in the history database, so they can be recalled with Ctrl+R, the history browser, and the up arrow like typed commands. Previously they were echoed and evaluated but only saved in some cases, depending on when the request arrived (#268).
- Experimental: IPC requests containing incomplete R expressions are now rejected before they can enter the continuation prompt.
