[](https://travis-ci.org/rust-lang/rust-installer)
A generator for the install.sh script commonly used to install Rust in
Unix environments. It is used By Rust, Cargo, and is intended to be
used by a future combined installer of Rust + Cargo.
# Usage
```
./gen-installer.sh --product-name=Rust \
--verify-bin=rustc \
--rel-manifest-dir=rustlib \
--success-message=Rust-is-ready-to-roll. \
--image-dir=./install-image \
--work-dir=./temp \
--output-dir=./dist \
--non-installed-prefixes=foo,bin/bar,lib/baz \
--package-name=rustc-nightly-i686-apple-darwin \
--component-name=rustc \
--legacy-manifest-dirs=rustlib \
--bulk-dirs=share/doc
```
Or, to just generate the script.
```
./gen-install-script.sh --product-name=Rust \
--verify-bin=rustc \
--rel-manifest-dir=rustlib \
--success-message=Rust-is-ready-to-roll. \
--output-script=install.sh \
--legacy-manifest-dirs=rustlib
```
*Note: the dashes in `success-message` are converted to spaces. The
script's argument handling is broken with spaces.*
To combine installers.
```
./combine-installers.sh --product-name=Rust \
--verify-bin=rustc \
--rel-manifest-dir=rustlib \
--success-message=Rust-is-ready-to-roll. \
--work-dir=./temp \
--output-dir=./dist \
--non-installed-overlay=./overlay \
--package-name=rustc-nightly-i686-apple-darwin \
--legacy-manifest-dirs=rustlib \
--input-tarballs=./rustc.tar.gz,cargo.tar.gz
```
# Future work
* Make install.sh not have to be customized, pull it's data from a
config file.
* Install an uninstall.sh script.
* Allow components to be selected during install.
* Allow components to be modified from an existing install.
* Be more resiliant to installation failures, particularly if the disk
is full.
* Pre-install and post-uninstall scripts.
* Make the verify-bin a per-component option.
* Be more thoughtful about overwriting existing files.
* Allow components to depend on or disallow other components.
* Sanity check that expected destination dirs (bin, lib, share exist)?
* Add --docdir flag. Is there a standard name for this?
* Remove empty directories on uninstall.
* Detect mismatches in --prefix, --mandir, etc. in follow-on
installs/uninstalls.
* Fix argument handling for spaces.
* Add --bindir.
