# Tazelish Tazelish installs [Tazel](https://tazel.net/) and chooses which version of it runs. It is for those who use Tazel alone; the toolchain manager of the whole of Tala is Talup. Tazelish runs on Linux (glibc 2.39 or newer, or musl 1.2.4 or newer), macOS 14 or newer and Windows with PowerShell 5.1; it does not run on BSD. ```text tazelish install 0.4.0.3 a release: MAJOR.SEMIMAJOR.MINOR.PATCH tazelish install unstable the newest unstable build tazelish install nightly the newest nightly build tazelish install 2026-11-05-nightly the nightly build of a day tazelish use [--force] 0.4.0.3 writes the version to ./tazelish.txt tazelish default [--force] nightly writes the version to the config.txt of the user tazelish self update|remove|purge tazelish help [command] ``` `tazelish.txt` and `config.txt` hold one version each, written as it is written after `tazelish install`. The nearest `tazelish.txt`, in the current folder or a folder above it, comes first; `config.txt`, at `$HOME/.tazelish/config.txt` or `%USERPROFILE%\.tazelish\config.txt`, counts where none names a version. `use` and `default` refuse to write over a file that exists unless `--force` is given. This build reads the command line, the versions and both files. `install` and `self` download from `static.tazel.net`, which this build does not do; they end with exit code 1. ## Building Tazelish is C++17, built with Bazel through Bazelisk: ```bash bazelisk test //... bazelisk build //:tazelish ``` On Windows it is compiled by clang-cl: set `BAZEL_LLVM` to the folder of an LLVM installation first, for example `C:\Program Files\LLVM`. The code of Tazelish throws no exceptions and builds with warnings as errors. | Folder | Holds | | --- | --- | | `Headers/Progmasoft/Tazelish/` | the interfaces: versions, the command line, the version files, the help | | `Sources/` | their implementation and `Main.cpp` | | `Tests/` | the tests, written with [Catch3](https://github.com/Progmasoft/catch3) | | `Build/` | a patch of rules_cc for clang-cl | ## Licence MPL-2.0 with the Progmasoft Exception 2.0; see [LICENSE.txt](LICENSE.txt) and [LICENSES/](LICENSES/AdditionRef-Progmasoft-Exception-2.0.txt).
