Cairo 1.0 installer

This tool installs Cairo 1.0.

Prerequisites

Git installed.

Rust installed. You can easilly install it running:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Installation / Update / Uninstallation

Once prerequisites have been installed correctly:

Install

If you wish to install a specific release of Cairo rather than the latest head, set the CAIRO_GIT_TAG environment variable (e.g. export CAIRO_GIT_TAG=v1.0.0-alpha.6).

curl -L https://github.com/franalgaba/cairo-installer/raw/main/bin/cairo-installer | bash

After installing, follow these instructions to set up your shell environment.

Update

rm -fr ~/.cairo
curl -L https://github.com/franalgaba/cairo-installer/raw/main/bin/cairo-installer | bash

Uninstall

Cairo is installed within $CAIRO_ROOT (default: ~/.cairo). To uninstall, just remove it:

rm -fr ~/.cairo

then remove these three lines from .bashrc:

export PATH="$HOME/.cairo/target/release:$PATH"

and finally, restart your shell:

exec $SHELL

Set up your shell environment for Cairo

• Define environment variable CAIRO_ROOT to point to the path where Cairo will store its data. $HOME/.cairo is the default. If you installed Cairo via Git checkout, we recommend to set it to the same location as where you cloned it.
• Add the cairo-* executables to your PATH if it's not already there

The below setup should work for the vast majority of users for common use cases.

• For bash:

  Stock Bash startup files vary widely between distributions in which of them source which, under what circumstances, in what order and what additional configuration they perform. As such, the most reliable way to get Cairo in all environments is to append Cairo configuration commands to both .bashrc (for interactive shells) and the profile file that Bash would use (for login shells).

  First, add the commands to ~/.bashrc by running the following in your terminal:

  echo 'export CAIRO_ROOT="$HOME/.cairo"' >> ~/.bashrc
  echo 'command -v cairo-compile >/dev/null || export PATH="$CAIRO_ROOT/target/release:$PATH"' >> ~/.bashrc
  

  Then, if you have ~/.profile, ~/.bash_profile or ~/.bash_login, add the commands there as well. If you have none of these, add them to ~/.profile.

  • to add to ~/.profile:

    echo 'export CAIRO_ROOT="$HOME/.cairo"' >> ~/.profile
    echo 'command -v cairo-compile >/dev/null || export PATH="$CAIRO_ROOT/target/release:$PATH"' >> ~/.profile
    

  • to add to ~/.bash_profile:

    echo 'export CAIRO_ROOT="$HOME/.cairo"' >> ~/.bash_profile
    echo 'command -v cairo-compile >/dev/null || export PATH="$CAIRO_ROOT/target/release:$PATH"' >> ~/.bash_profile
    

• For Zsh:

  echo 'export CAIRO_ROOT="$HOME/.cairo"' >> ~/.zshrc
  echo 'command -v cairo-compile >/dev/null || export PATH="$CAIRO_ROOT/target/release:$PATH"' >> ~/.zshrc
  

  If you wish to get Cairo in noninteractive login shells as well, also add the commands to ~/.zprofile or ~/.zlogin.

• For Fish shell:

  If you have Fish 3.2.0 or newer, execute this interactively:

  set -Ux CAIRO_ROOT $HOME/.cairo
  fish_add_path $CAIRO_ROOT/target/release
  

  Otherwise, execute the snippet below:

  set -Ux CAIRO_ROOT $HOME/.cairo
  set -U fish_user_paths $CAIRO_ROOT/target/release $fish_user_paths
  

In MacOS, you might also want to install Fig which provides alternative shell completions for many command line tools with an IDE-like popup interface in the terminal window. (Note that their completions are independent from Cairo's codebase so they might be slightly out of sync for bleeding-edge interface changes.)

Restart your shell

for the PATH changes to take effect.

exec "$SHELL"
