Chris Kay 7c4e1eea61 build: unify verbosity handling This change introduces a few helper variables for dealing with verbose and silent build modes: `silent`, `verbose`, `q` and `s`. The `silent` and `verbose` variables are boolean values determining whether the build system has been configured to run silently or verbosely respectively (i.e. with `--silent` or `V=1`). These two modes cannot be used together - if `silent` is truthy then `verbose` is always falsy. As such: make --silent V=1 ... results in a silent build. In addition to these boolean variables, we also introduce two new variables - `s` and `q` - for use in rule recipes to conditionally suppress the output of commands. When building silently, `s` expands to a value which disables the command that follows, and `q` expands to a value which supppresses echoing of the command: $(s)echo 'This command is neither echoed nor executed' $(q)echo 'This command is executed but not echoed' When building verbosely, `s` expands to a value which disables the command that follows, and `q` expands to nothing: $(s)echo 'This command is neither echoed nor executed' $(q)echo 'This command is executed and echoed' In all other cases, both `s` and `q` expand to a value which suppresses echoing of the command that follows: $(s)echo 'This command is executed but not echoed' $(q)echo 'This command is executed but not echoed' The `s` variable is predominantly useful for `echo` commands, where you always want to suppress echoing of the command itself, whilst `q` is more useful for all other commands.

Chris Kay 7c4e1eea61 build: unify verbosity handling

This change introduces a few helper variables for dealing with verbose
and silent build modes: `silent`, `verbose`, `q` and `s`.

The `silent` and `verbose` variables are boolean values determining
whether the build system has been configured to run silently or
verbosely respectively (i.e. with `--silent` or `V=1`).

These two modes cannot be used together - if `silent` is truthy then
`verbose` is always falsy. As such:

    make --silent V=1

... results in a silent build.

In addition to these boolean variables, we also introduce two new
variables - `s` and `q` - for use in rule recipes to conditionally
suppress the output of commands.

When building silently, `s` expands to a value which disables the
command that follows, and `q` expands to a value which supppresses
echoing of the command:

    $(s)echo 'This command is neither echoed nor executed'
    $(q)echo 'This command is executed but not echoed'

When building verbosely, `s` expands to a value which disables the
command that follows, and `q` expands to nothing:

    $(s)echo 'This command is neither echoed nor executed'
    $(q)echo 'This command is executed and echoed'

In all other cases, both `s` and `q` expand to a value which suppresses
echoing of the command that follows:

    $(s)echo 'This command is executed but not echoed'
    $(q)echo 'This command is executed but not echoed'

The `s` variable is predominantly useful for `echo` commands, where you
always want to suppress echoing of the command itself, whilst `q` is
more useful for all other commands.
