William Melody fe48de86f1 Update version to 3.1.1 2019-11-21 19:28:51 -08:00
William Melody e10d116510 Handle platform-specific `sed -i` requirements. 
`sed -i` on macOS requires an extension, but on Linux that extension can
cause errors. Use a platform check to only include the extension on
macOS.

William Melody dfcb37b3b6 Remove unused option normalization. 
This program only really accepts one short argument, `-h`, so this
extra complexity isn't necessary.

 2018-04-15 15:01:34 -07:00
William Melody 80edd464b6 Use explicit escaping for "\\n" newlines. 
Backslash is literal, so explicitly escape it rather than rely on
fallback behavior.

William Melody 32c5be4dcc Revert "Prefix `_debug` strings with '•' to avoid highlighting bugs." 
This reverts commit 921afd7155.

The reverted commit did not succeed in fixing highlighting bugs.
 2017-03-01 20:51:36 -08:00
William Melody 921afd7155 Prefix `_debug` strings with '•' to avoid highlighting bugs. 
GitHub's syntax highlighting doesn't work well when strings contain
function names with parentheses, so add character to the beginning of
the string to see whether this makes it better.

William Melody f5d0f827e0 Bump version to 2.4.0. 2017-03-01 20:24:12 -08:00

William Melody e0790f6a4c Bump version to 2.3.0. 2017-03-01 16:25:03 -08:00
William Melody 99b175f134 Add `--auto-sudo` option and expand option documentation. 
Using `sudo` within a script is generally considered poor practice, so
by default an error message is printed when the user attempts to perform
a write operation without sufficient permissions.

One way to deal avoid this error message is to alias `hosts` to `sudo
hosts`, but this then requires `sudo` for all operations and not just
write operations.

The new `--auto-sudo` option flag provides a way to automatically invoke
a write command with `sudo` when the user doesn't have write
permissions.

In order to provide cleaner documentation for this option, include more
option documentation in README.md.

William Melody 0925735153 Bump version to 2.2.0. 2017-03-01 14:29:04 -08:00
William Melody 347189c059 Add `search` usage to primary `help` output. 
Update README.md to more accurately reflect `help` output.
 2017-03-01 13:45:19 -08:00
William Melody 265a1c732e Add `block` and `unblock` functions. 
`block` and `unblock` set the given <hostname> to the IPv4 and IPv6
loopback addresses.
 2017-03-01 13:43:10 -08:00
William Melody 73ffcffb38 Add `hosts search` function. 
`hosts search` wraps `hosts list`, providing a slightly more intuitive
interface.
 2017-03-01 12:46:27 -08:00
William Melody 703d665a32 Use `read` with `-r` option. 
ShellCheck SC2162: read without -r mangle backslashes

 2017-03-01 12:05:59 -08:00
William Melody 4194b25459 Use `HEREDOC` rather than `EOM` to define heredocs. 2017-03-01 11:42:26 -08:00
William Melody f7675f360e Bump version to 2.1.6. 2016-03-24 17:32:26 -07:00
William Melody 149a51662e Handle blank arguments string when assigning to `$_RAW_OPTIONS`. 
When `$*` is specified with quotes and braces as `"${*}"`, a blank
argument array results in an error in older versions of bash. Remove
the braces to avoid this error.
 2016-03-24 17:30:30 -07:00
William Melody 187222614a Use braces in all variable references. 
Braces are only required in certain cases, but the cognitive overhead in
keeping track of which cases require braces can be reduced by simply
always using them.

Example: `${NAME}`

Retain more widely-used braces `$NAME` convention in documentation.

William Melody f7c7aef173 Update help/usage formatting. 2016-01-26 20:25:16 -08:00
William Melody eeab6e8ba1 Alphabetize subcommands in Usage. 
It's easier to find a subcommand in an alphabetical list.
 2016-01-15 16:52:41 -08:00
William Melody 80a8e48c10 Use `if..then` in `show` to avoid non-zero exits. 
The `[[ ... ]] && ...` conditional style results in non-zero exits when
the test is false. Moving this to a traditional `if..then` style avoids
this behavior while also being more explicit about the objective of the
code. `|| return 0` or `|| exit 0` could have been added as an
alternative way to avoid the non-zero exit behavior, but is not used in
this case because the traditional `if..then` style is more common.

William Melody 4d1adbdf52 Bump version to 2.1.4. 2015-11-25 18:03:19 -08:00
William Melody 21069fb68d Add quotes around strings in `list` command argument tests. 
Quoting these strings more clearly communicates that these are not
variable or function names, and that the string itself is what is
being tested for.
 2015-11-23 11:16:03 -08:00
William Melody 59e404f865 Add newlines around prompt section of `remove`. 
The convention used in this project is to include newlines around
longer, grouped conditionals in order to provide better visual
separation.
