Cargo Liner

Configuration-oriented wrapper around `cargo install`

GitHub release (latest by date including pre-releases)

car·go·lin·er, noun:

a cargo ship that sails regularly between designated ports according to a published schedule.

Summary

Cargo Liner is a tool to help one who has packages currently installed or to be installed through the official cargo install command to install and maintain them up-to-date by editing a small and stable configuration file located at $CARGO_HOME/liner.toml.

Goals:

Simple and intuitive API.
Stable configuration file: avoid editing it automatically.
Actually use cargo install, cargo search or cargo config get and not much else.

Non-goals:

Super-duper stability guarantees.
Re-implementing half of Cargo for small functionalities.
Being """pretty""" above all else.
Handling the synchronization of the configuration file between various hosts.

Rationale

cargo install works very well to download, compile and install a binary package. However, it does not offer means to update currently installed programs without having to specify them manually one by one on the CLI. That becomes quickly bothersome when having to maintain several packages up-to-date, especially if it needs to be done on multiple workstations.

Some projects, such as cargo-update or cargo-updater, exist in order to solve this issue. Their strategy is to exploit the $CARGO_HOME/.crates.toml and $CARGO_HOME/.crates2.json files that Cargo generates and maintains in order to track which packages are installed, their exact version, where they were downloaded from and which programs they have installed. This strategy is quite effective, so if you are looking for exactly that, then check them out.

However, some problems are still not solved like this: when configuring a new workstation, there is still the need to specify each package manually at least once; when adding a new package on one already-configured workstation, there is still the need to install it manually on all others. These tools lack sharing and synchronization.

The current project therefore inspires itself from tools such as zplug for Zsh and vim-plug for Vim by taking orders from a central configuration file. The tool then simply runs cargo search for all packages listed in that file in order to retrieve their latest versions available and then cargo install for those that do indeed need an install or update using the results from the search. That enables one to install and maintain all packages up-to-date, but also to keep all of one's workstations synchronized by sharing the file between them in some way, using Git for example.

Installation

Run: cargo install cargo-liner.
Create the configuration file to be located at: $CARGO_HOME/liner.toml.
- See the reference documentation about Cargo Home if you have trouble locating the directory.
If you are using a different Cargo installation root than $CARGO_HOME, please make sure it is properly configured in the $CARGO_INSTALL_ROOT environment variable or the install.root key of the $CARGO_HOME/config.toml file so that the current tool may be able to detect that on itself. See the cargo install documentation for more details about this.

Populate the file with packages you wish to be installed, for example:

[packages]
cargo-expand = "*"
cargo-tarpaulin = "~0.22"
nu = "=0.71.0"
ripgrep = { version = "13.0.0", all-features = true }

    [packages.sqlx-cli]
    version = "0.6.2"
    default-features = false
    features = ["native-tls", "postgres"]

or use cargo liner import to do it automatically for you, see below for more detailed explanations.

Usage

Configuration

The file must be located at $CARGO_HOME/liner.toml and contain a properly-formed TOML document respecting the following format:

[packages]
package-name-1 = "version-req-1"
package-name-2 = "version-req-2"

    [packages.package-name-3]
    version = "version-req-3"
    all-features = boolean
    default-features = boolean
    features = ["feature-1", "feature-2"]
    index = "http://example.com/"
    registry = "example-registry"
    git = "http://example.com/exa/mple.git"
    branch = "branch"
    tag = "tag"
    rev = "SHA1"
    path = "/a/b/c"
    bins = ["bin1", "bin2"]
    all-bins = boolean
    examples = ["ex1", "ex2"]
    all-examples = boolean
    force = boolean
    ignore-rust-version = boolean
    frozen = boolean
    locked = boolean
    offline = boolean
    extra-arguments = ["--arg1", "--arg2"]
    environment = { ENV1 = "abc", ENV2 = "def" }
    skip-check = boolean
    no-fail-fast = boolean
#...

[defaults]
    [defaults.ship]
    no-self = boolean
    only-self = boolean
    skip-check = boolean
    no-fail-fast = boolean
    force = boolean

where:

packages (mandatory): map of package name to package details instructing which and how packages should be installed or updated:
- version (mandatory): version requirement string to use when installing or updating the associated package; this is the detailed field set when only using the simple configuration style.
- all-features (optional): boolean that, when set to true, enables the --all-features flag of cargo install.
- default-features (optional): boolean that, when set to false, enables the --no-default-features flag of cargo install.
- features (optional): list of strings instructing which of the associated crate's Cargo features should be enabled when building it.
- index (optional): string specifying the registry index to install from.
- registry (optional): string specifying the registry to use.
- git (optional): string specifying the Git URL to install from.
- branch (optional): string specifying the branch to use when installing from Git.
- tag (optional): string specifying the tag to use when installing from Git.
- rev (optional): string specifying the commit to use when installing from Git.
- path (optional): string specifying the filesystem path to local crate to install from.
- bins (optional): list of strings specifying the binaries to install among the targeted crate's binary targets, passed onto Cargo as a repetition of its --bin option.
- all-bins (optional): boolean that, when true, passes the --bins CLI option to Cargo, thus installing all binaries of the package.
- examples (optional): list of strings specifying the examples to install among the targeted crate's example targets, passed onto Cargo as a repetition of its --example option.
- all-examples (optional): boolean that, when true, passes the --examples CLI option to Cargo, thus installing all examples of the package.
- force (optional): boolean that, when true, passes --force to Cargo, thus potentially overwriting existing binaries or examples; only useful if --skip-check is passed as well.
- ignore-rust-version (optional): boolean that, when true, passes the --ignore-rust-version CLI option to Cargo, thus ignoring rust-version specifications in packages.
- frozen (optional): boolean that, when true, passes the --frozen CLI option to Cargo, thus requiring the package's Cargo.lock and Cargo's cache to be both up-to-date.
- locked (optional): boolean that, when true, passes the --locked CLI option to Cargo, thus requiring the package's Cargo.lock to be up-to-date.
- offline (optional): boolean that, when true, passes the --offline CLI option to Cargo, thus requiring Cargo to run without accessing the network; can only be of use if --skip-check is passed as well.
- extra-arguments (optional): list of strings given as additional arguments to cargo install for the associated package and located between the last one given by Cargo Liner and the following -- seperating options from fixed arguments. This can be used in order to successfully manage a package using a Cargo Liner version that does not yet implement the desired option.
- environment (optional): map of string to strings specifying which and how environment variables should be set for the spawned cargo install process.
- skip-check (optional): boolean that, when true, excludes the associated package from the version check and always includes it in the packages to be installed or updated. This is the direct equivalent of --skip-check from the CLI, except that the CLI's is global as all packages will be excluded from the version check and the configuration's is partial as only the concerned package will be. It can be used in order to get the best out of both modes of execution: if a package reveals problematic somehow, the option can be used for it while the other packages remain as-is. The CLI option keeps the priority: if set, any version checking step is still entirely skipped, which should prove a bit more forceful than if the configuration option was set for all listed packages.
- no-fail-fast (optional): boolean that, when true, makes the operation proceed as though --no-fail-fast was given, but only for the associated package: in case of an error of the call to cargo install for it, the operation will not stop here and continue on with the next package, but if the next package does not have the option set in its configuration and fails to install somehow, the operation will still abruptly fail there. The CLI option keeps the priority: if set, it is as though the configuration option was set for all listed packages.
defaults (optional): map of maps that enables setting values to use by default when running some operations; they are grouped by CLI command:
- ship (optional): map of string to booleans corresponding to the eponymous CLI command:
  - no-self (optional): boolean that, when true, enables the --no-self flag by default.
  - only-self (optional): boolean that, when true, enables the --only-self flag by default.
  - skip-check (optional): boolean that, when true, enables the --skip-check flag by default.
  - no-fail-fast (optional): boolean that, when true, enables the --no-fail-fast flag by default.
  - force (optional): boolean that, when true, enables the --force flag by default.

with the following constraints, mostly enforced by Cargo, but also by TOML:

package-name-* must be a valid package name, i.e. match [a-zA-Z][a-zA-Z0-9_-]* or something like that.
version-req-* must be a valid SemVer requirement, Cargo style. In particular, the catch-all wildcard * can be used to require the latest version available.
feature-* must be the name of a Cargo feature defined by the package being installed, which has constraints similar to a package name; in particular, it shouldn't contain a comma.
--arg* must be the name of a cargo install CLI argument.
ENV* should be the name of a cargo install environment variable.
boolean is a TOML boolean, either true or false.

See the below CLI documentation for the association between CLI flags, environment variables and configuration items. The CLI has precedence over the environment and the environment over the configuration.

This configuration can serve in particular for customizing the way Cargo Liner itself is updated. Indeed, when self-updating is enabled, which is the case by default, then Cargo Liner is added to the list of packages just as if it actually were in the configuration file with a simple "*" version requirement, but only if it is not there yet. This enables treating Cargo Liner just like any other package, which it is after the configuration is parsed. Therefore, simply add an entry under cargo-liner in order to pass non-default options to cargo install when self-updating.

CLI

A few commands are available:

$ cargo help liner
Cargo subcommand to install and update binary packages listed in
configuration.

Usage: cargo liner [OPTIONS] [COMMAND]

Commands:
  ship         The default command if omitted: install and update
               configured packages
  import       Import the `$CARGO_HOME/.crates.toml` Cargo-edited
               save file as a new Liner configuration file
  completions  Generate an auto-completion script for the given shell
  help         Print this message or the help of the given
               subcommand(s)

Options:
  -v, --verbose...
          Be more verbose. Use multiple times to be more and more so
          each time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, DEBUG and above messages of
          only this crate are logged and error backtraces are shown
          (`RUST_BACKTRACE=1`). When used twice, DEBUG and above
          messages of all crates are logged, `-v` is given to Cargo
          calls (details ran commands), and error backtraces are
          fully shown (`RUST_BACKTRACE=full`). When used three times
          or more, TRACE and above messages of all crates are logged,
          `-vv` is given to Cargo calls (includes build output) and
          error backtraces are fully shown (`RUST_BACKTRACE=full`).
          This takes precedence over the environment.

  -q, --quiet...
          Be quieter. Use multiple times to be more and more so each
          time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, WARN and above messages of only
          this crate are logged. When used twice, ERROR messages of
          all crates are logged. When used three times or more, no
          message will be logged, including Cargo's by passing `-q`
          to it and error reports are silenced. This takes precedence
          over the environment.

      --color <WHEN>
          Control the coloring of the logging output.
          
          This enables one to manually specify when should the logs
          and error reports be colored or not, for example if the
          automatic detection is either not wished or not functional.
          The value is also passed onto calls to Cargo.
          
          [default: auto]
          [possible values: auto, always, never]

  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

Default command

When the subcommand is omitted, it will use the ship subcommand with default options. See its specific documentation for more details.

Simply run cargo liner in order to:

Read packages from the configuration file.
Detect currently-installed packages from Cargo's installation.
Check the latest available version for each of them.
Install or update the ones that need to, respecting the version requirements.
Self-update.

Example output if bat and cargo-expand are required:

`ship` subcommand

The main command: do the installing and updating of packages.

$ cargo liner help ship
The default command if omitted: install and update configured
packages.

Self-updating is enabled by default.

Usage: cargo liner ship [OPTIONS]

Options:
  -n, --no-self
          Disable self-updating.
          
          Cannot be used in conjunction with `--only-self`.
          
          [default: false]
          
          [env: `CARGO_LINER_SHIP_NO_SELF`]
          
          [config: `defaults.ship.no-self`]

      --with-self
          Negation of `--no-self` that overrides it and restores the
          default behavior as if absent, i.e. self-update

  -s, --only-self
          Only self-update and do not install or update any other
          package.
          
          Cannot be used in conjunction with `--no-self`.
          
          [default: false]
          
          [env: `CARGO_LINER_SHIP_ONLY_SELF`]
          
          [config: `defaults.ship.only-self`]

      --no-only-self
          Negation of `--only-self` that overrides it and restores
          the default behavior as if absent, i.e. install or update
          other packages as well

  -c, --skip-check
          Skip the summary version check and directly call `cargo
          install` on each configured package.
          
          The version check is relatively quick and enables skipping
          calls to `cargo install` when no update is required, which
          saves quite a bit of time. However, if you wish, this
          option is still available in order not to run the check:
          doing so will probably take more time in the end most of
          the time, except if you have a very small amount of
          packages configured (e.g. one or two) or if all or almost
          all packages are not already installed.
          
          It can also be used as a workaround in case a certain
          operation fails in your particular environment, for
          example: reading from `.crates.toml` under the
          `$CARGO_HOME` or `$CARGO_INSTALL_ROOT` directory or making
          requests to the registry. These operations will thus be
          entirely skipped.
          
          [default: false]
          
          [env: `CARGO_LINER_SHIP_SKIP_CHECK`]
          
          [config: `defaults.ship.skip-check`]

      --no-skip-check
          Negation of `--skip-check` that overrides it and restores
          the default behavior as if absent, i.e. perform the usual
          version check

  -k, --no-fail-fast
          Disable the default fail-fast execution of `cargo
          install`s.
          
          By default, whenever a call to `cargo install` fails for
          any reason, the overall operation is stopped as soon as
          possible. In some cases, such as packages simply failing to
          compile, this is a bit too restrictive as it prevents
          installing the following packages. The option it therefore
          provided in order to make the installation keep on going by
          continuing to call `cargo install` on each configured
          package, even if some previous one failed. However, in case
          any of the packages fails to install and the option is
          used, an error will still be reported at the end,
          containing an indication of all the packages that failed to
          install.
          
          This is not to be confused with Cargo's `--keep-going`
          build option: it disables fast-failing between crate
          compilations, while the current one disables fast-failing
          between entire calls to `cargo install`; in fact,
          `--keep-going` is never passed onto Cargo. It is neither to
          be confused with `cargo test --no-fail-fast` since `cargo
          test` is never used.
          
          [default: false]
          
          [env: `CARGO_LINER_SHIP_NO_FAIL_FAST`]
          
          [config: `defaults.ship.no-fail-fast`]

      --fail-fast
          Negation of `--no-fail-fast` that overrides it and restores
          the default behavior as if absent, i.e. stop as soon as the
          first error occurs

  -f, --force
          Force overwriting existing crates or binaries.
          
          Passes the option flag onto each call of `cargo install`.
          It will, for example, redownload, recompile and reinstall
          every configured package when used in conjunction with
          `--skip-check`.
          
          [default: false]
          
          [env: `CARGO_LINER_SHIP_FORCE`]
          
          [config: `defaults.ship.force`]

      --no-force
          Negation of `--force` that overrides it and restores the
          default behavior as if absent, i.e. don't pass the argument
          onto Cargo

  -v, --verbose...
          Be more verbose. Use multiple times to be more and more so
          each time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, DEBUG and above messages of
          only this crate are logged and error backtraces are shown
          (`RUST_BACKTRACE=1`). When used twice, DEBUG and above
          messages of all crates are logged, `-v` is given to Cargo
          calls (details ran commands), and error backtraces are
          fully shown (`RUST_BACKTRACE=full`). When used three times
          or more, TRACE and above messages of all crates are logged,
          `-vv` is given to Cargo calls (includes build output) and
          error backtraces are fully shown (`RUST_BACKTRACE=full`).
          This takes precedence over the environment.

  -q, --quiet...
          Be quieter. Use multiple times to be more and more so each
          time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, WARN and above messages of only
          this crate are logged. When used twice, ERROR messages of
          all crates are logged. When used three times or more, no
          message will be logged, including Cargo's by passing `-q`
          to it and error reports are silenced. This takes precedence
          over the environment.

      --color <WHEN>
          Control the coloring of the logging output.
          
          This enables one to manually specify when should the logs
          and error reports be colored or not, for example if the
          automatic detection is either not wished or not functional.
          The value is also passed onto calls to Cargo.
          
          [default: auto]
          [possible values: auto, always, never]

  -h, --help
          Print help (see a summary with '-h')

Simply run cargo liner ship in order to:

Read packages from the configuration file.
Read currently installed packages from the Cargo-managed .crates.toml file under the $CARGO_INSTALL_ROOT directory if cargo config get is able to retrieve its value from either the environment variable or the install.root configuration item in $CARGO_HOME/config.toml, or fall back to searching the file under the default $CARGO_HOME directory if the first attempt fails for any reason, the simple absence of the setting being one of them. See the cargo install documentation for more details about this. Whenever the first attempt fails, it is logged as a DEBUG message before attempting the default, so use -vv to investiguate if your configuration seems not to be taken into account.
Check the latest available version for each of them using cargo search.
Run cargo install for each that needs an install or update, respecting the version requirements.
Self-update only if --no-self is not given.

cargo install

`import` subcommand

This command is meant to be used upon installing the tool and using it for the first time: it populates the configuration file with currently-installed packages.

$ cargo liner help import
Import the `$CARGO_HOME/.crates.toml` Cargo-edited save file as a new
Liner configuration file.

Star versions are used by default. The version transformation options
are mutually exclusive.

Usage: cargo liner import [OPTIONS]

Options:
  -e, --exact
          Import package versions as "exact versions", i.e. prepended
          with an equal operator.
          
          Cannot be used in conjunction with either `--compatible` or
          `--patch`. Default: `false`, i.e. use a star requirement.

  -c, --compatible
          Import package versions as "compatible versions", i.e.
          prepended with a caret operator.
          
          Cannot be used in conjunction with either `--exact` or
          `--patch`. Default: `false`, i.e. use a star requirement.

  -p, --patch
          Import package versions as "patch versions", i.e. prepended
          with a tilde operator.
          
          Cannot be used in conjunction with either `--exact` or
          `--compatible`. Default: `false`, i.e. use a star
          requirement.

  -f, --force
          Overwrite the current configuration file if it already
          exists.
          
          Default: `false`, i.e. return an error in case the file
          already exists.

  -s, --keep-self
          Also import this `cargo-liner` package into the
          configuration, for example in order to specify a certain
          version requirement later on.
          
          Default: `false`, i.e. exclude the current package from the
          list of packages to install or update in the resulting
          configuration file. Note however that the `ship` command
          will still self-update by default.

  -l, --keep-local
          Also import all locally-installed packages into the
          configuration. This means packages installed via `cargo
          install --path <path>` will be present in the
          configuration.
          
          Default: `false`, i.e. exclude all packages installed via
          `cargo install --path <path>` from the list of packages to
          install or update in the resulting configuration file.

  -v, --verbose...
          Be more verbose. Use multiple times to be more and more so
          each time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, DEBUG and above messages of
          only this crate are logged and error backtraces are shown
          (`RUST_BACKTRACE=1`). When used twice, DEBUG and above
          messages of all crates are logged, `-v` is given to Cargo
          calls (details ran commands), and error backtraces are
          fully shown (`RUST_BACKTRACE=full`). When used three times
          or more, TRACE and above messages of all crates are logged,
          `-vv` is given to Cargo calls (includes build output) and
          error backtraces are fully shown (`RUST_BACKTRACE=full`).
          This takes precedence over the environment.

  -q, --quiet...
          Be quieter. Use multiple times to be more and more so each
          time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, WARN and above messages of only
          this crate are logged. When used twice, ERROR messages of
          all crates are logged. When used three times or more, no
          message will be logged, including Cargo's by passing `-q`
          to it and error reports are silenced. This takes precedence
          over the environment.

      --color <WHEN>
          Control the coloring of the logging output.
          
          This enables one to manually specify when should the logs
          and error reports be colored or not, for example if the
          automatic detection is either not wished or not functional.
          The value is also passed onto calls to Cargo.
          
          [default: auto]
          [possible values: auto, always, never]

  -h, --help
          Print help (see a summary with '-h')

For example, if you had previously installed:

bat@0.22.1
cargo-make@0.36.3
cargo-outdated@0.11.1

Then running cargo liner import will result in the following configuration file, if it does not already exist:

[packages]
bat = "*"
cargo-make = "*"
cargo-outdated = "*"

The command will by default exclude from the destination file:

cargo-liner: would duplicate the dedicated self-updating; the -s/--keep-self option flag is there to disable this exclusion.
all locally-installed packages, i.e. the ones installed through cargo install --path=...: avoids polluting the destination file with packages that cannot be updated anyway since they have no guarantee of existing in the registry used; the -l/--keep-local option flag is there to disable this exclusion.

The command will by default import the packages with star version requirements. The --exact, --compatible and --patch options are provided in order to customize how the currently-installed versions are imported into version requirements: --exact will prepend them with =, --compatible with ^, and --patch with ~.

For example, using the previous three packages already installed, running cargo liner import --patch would give:

[packages]
bat = "~0.22.1"
cargo-make = "~0.36.3"
cargo-outdated = "~0.11.1"

The file can of course be edited manually afterwards, as intended.

`completions` subcommand

This enables obtaining CLI auto-completion in a shell for the current project:

$ cargo liner help completions
Generate an auto-completion script for the given shell.

The script is generated for `cargo-liner`, but with arguments rooted
on `cargo-liner liner`, thus making auto-completing work when typing
`cargo liner`. The generated script is emitted to standard output.

Usage: cargo liner completions [OPTIONS] <SHELL>

Arguments:
  <SHELL>
          The shell flavor to use when generating the completions
          
          [possible values: bash, elvish, fish, powershell, zsh]

Options:
  -v, --verbose...
          Be more verbose. Use multiple times to be more and more so
          each time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, DEBUG and above messages of
          only this crate are logged and error backtraces are shown
          (`RUST_BACKTRACE=1`). When used twice, DEBUG and above
          messages of all crates are logged, `-v` is given to Cargo
          calls (details ran commands), and error backtraces are
          fully shown (`RUST_BACKTRACE=full`). When used three times
          or more, TRACE and above messages of all crates are logged,
          `-vv` is given to Cargo calls (includes build output) and
          error backtraces are fully shown (`RUST_BACKTRACE=full`).
          This takes precedence over the environment.

  -q, --quiet...
          Be quieter. Use multiple times to be more and more so each
          time.
          
          When omitted, INFO and above messages of only this crate
          are logged. When used once, WARN and above messages of only
          this crate are logged. When used twice, ERROR messages of
          all crates are logged. When used three times or more, no
          message will be logged, including Cargo's by passing `-q`
          to it and error reports are silenced. This takes precedence
          over the environment.

      --color <WHEN>
          Control the coloring of the logging output.
          
          This enables one to manually specify when should the logs
          and error reports be colored or not, for example if the
          automatic detection is either not wished or not functional.
          The value is also passed onto calls to Cargo.
          
          [default: auto]
          [possible values: auto, always, never]

  -h, --help
          Print help (see a summary with '-h')

Its result can either be saved to a file configured to be sourced (or equivalent) by your shell, or generated and evaluated (or equivalent) at each startup. For example with Zsh, adding:

[[ -f ~/.cargo/bin/cargo-liner ]] && eval "$(cargo liner -qqq completions zsh)"

to one's ~/.zshrc will enable the completions in every new shell, but only if Cargo Liner is indeed installed (that part may need to be adapted to your particular environment).
