Is your feature request related to a problem? Please describe.
blocking websites to work, I sometimes need to use a website for a limited amount of time to not sidetrack. Do you think it would be useful to add a time flag?

Describe the solution you'd like

$ hostctl enable -p youtube -t 15 # enable youtube profile for 15 minutes

Describe alternatives you've considered

$ hostcl enable -p youtube && sleep 900 && hostctl disable -p youtube

for my use case, I find myself wanting to enable all profiles except one.
Could we have a hostctl disable awesome --only?

Hi, to remain in line with other projects that provide a brew tap might I suggest creating another repo called homebrew-tap. This would allow you a central point for all your homebrew formulae (I hope you go on to create more projects, this one is great) as well as allowing users to install hostctl as well as subscribe to your tap with a single command brew install guumaster/tap/hostctl. This is the same way goreleaser does it (Gotta love a tool that "eats its own dogfood").

@BarbUk I've notice you added this: https://aur.archlinux.org/packages/hostctl-bin/. Does it need any automation?

The snap package is published on a strict confinement and cannot read any file outside it, so the input --from /any/file is a problem.

A workaround is to accept stdin input instead. Ex: hostctl add -p some < /path/to/file.

Maybe is useful to render output as different targets like json, yaml, html and markdown.

Changing tablewriter to go-pretty could help.

I'm thinking on adding a simple UI. Maybe some Vue frontend and a web server to perform the updates.

Or maybe something more like k9s

Not sure if this should be splitted to a separate binary and keep it separate from core functionality.

Add --watch flag to sync commands to monitor and react to changes on the origin system (docker, kubernetes, etc).

update docs and guides. remove -p flag.

Describe the bug
If you try to add a profile from a file that doesn't exists, it panic.

Expected behavior

Check for the source file and fail more gracefully on missing file.

Running a command prompt as admin and getting access denied error.

Using latest v1.1.1

My local account is in the Administrators group.

This is due to running your utility from a non-C drive; which fails. If I run it from the c:\ drive it succeeds. This is long standing bug in the GO language related to paths that is causing this. I posted about this a long time ago on another open source project. If I can find that post I'll add it here.

Describe the bug

Using the last version (binary or compiled), I can no longer add a new profile.

To Reproduce

With no profile named test

$ sudo hostctl add domains test test.com
Error: unknown profile name

Expected behavior

Domain test.com is added in a newly created test profile

System (please complete the following information):

• OS: Linux
• Version:

$ hostctl --version
hostctl version 1.0.5

As mentioned on #30 (comment) a toggle command can be used to change status on any given profile.

tools with logo are better than tools without it. I have less than zero skills to do it.

If anyone have some idea of a minimal and simple logo that can match with the features of this CLI tool, is welcome to create a PR and add ideas, images or designs.

Any ideas how to integrate this with Docker?

I need something that recognizes when a container starts and add then a hostname to the hosts file with the ip of the container (maybe the project name from docker-compose). Would be fantastic to automate, so I don’t have to remember all the service names and there port redirections.

Describe the bug
hostctl appears to not be idempotent when it adds entries for the same domain + ip when run multiple times.

To Reproduce
Run this command multiple times (--uniq doesn't seem to make a difference)

touch /tmp/test-hosts; hostctl add domains test domain1 --ip 127.0.0.1 --host-file /tmp/test-hosts

Current behavior

##################################################################
# Content under this line is handled by hostctl. DO NOT EDIT.
##################################################################

# profile.on test
127.0.0.1 domain1
127.0.0.1 domain1
127.0.0.1 domain1
127.0.0.1 domain1
# end

Expected behavior
When running the command above, /tmp/test-hosts should only contain one uniq entry.

Example of what it should look like

##################################################################
# Content under this line is handled by hostctl. DO NOT EDIT.
##################################################################

# profile.on test
127.0.0.1 domain1
# end

System (please complete the following information):

• OS: Mac
• Version: 10.15.7 (19H15)

Additional context

hostctl --version
hostctl version 1.0.14

Describe the bug

In this hosts file you can find the following line:

# 0.0.0.0  www.youtube-nocookie.com #[affects various videos]

When you add the file with hostctl, it becomes:

0.0.0.0 www.youtube-nocookie.com
0.0.0.0 #[affects
0.0.0.0 various
0.0.0.0 videos]

To Reproduce

Download the list and add it via hostctl add

Expected behavior
Comments should not turn into entries.
They should be either stripped altogether or preserved.

System (please complete the following information):

• OS: archlinux
• hostctl version 1.0.14 from AUR

Thinks I'd like to add:

• hostctl sync k8s -n namespace -p profile
• hostctl sync minikube -p profile
• hostctl sync docker -p profile
• hostctl sync docker-compose -f docker-compose.yml -p profile

Also with a --watch flag to monitor and react to changes

hostctl status gives a different sorting each time it's invoked. Could you enforce an alphabetic sorting?

This would also make names with prefixes somewhat useful if you have a good number of profiles.

Add a common logger with coloring and TTY detection.

hostctl set -p mdserver --from c:\script\hostctl\mdserver_hosts.txt
Using hosts file: C:\Windows\System32\Drivers\etc\hosts
Error: truncate C:\Windows\System32\Drivers\etc\hosts: Access is denied.

Error: Cannot tap guumaster/tap: invalid syntax in tap!

Is your feature request related to a problem? Please describe.
I use /etc/hosts to block websites during work. for example, I block youtube, twitter, ycombinator, etc. I would love to have profiles for individual websites (e.g., sudo hostctl enable -p youtube) but at the same time have a group of profiles that I can manipulate all at once (e.g., sudo hostctl disable -p socialmedia).

Describe the solution you'd like

$ hostctl group socialmedia -p youtube twitter linkedin
$ hostctl disable -p socialmedia # disable all social media
$ hostcl enable -p youtube          # except for youtube

Maybe it's a good idea to split the program in smaller components, example:

• hostctl (core)
• hostctl-docker
• hostctl-k8s
• hostctl-ui (or web)

A kind of plugin system or so. Not sure if there is any example on Go to checkout.

choose a template and create a simple layout with all the doc and examples.

Displaying the version number as part of --help could help to identify issues from different versions.

i really want to use this by yum or dnf ( Centos )
may i ask this package manager repo. i wish that. my god~

Why not just have profiles the default argument in commands?
Instead of hostctl toggle -p awesome you'd have hostctl toggle awesome? (with -p still working for backward compatibility)

I get that the add command, for instance, can be convoluted and a flag (-p) to clearly define profile name is a healthy pattern. But profile as a default argument is straightforward for most other commands.

What do you think?

$ hostctl -v || hostctl --version
hostctl 0.10.0

or add it to the output of the help command?

Create commands and subcommands to enable autocompletion:

Is your feature request related to a problem? Please describe.
I use /etc/hosts to block websites during work and it exceeds 20,000 lines. When listing profiles, it all gets outputted.

Describe the solution you'd like
I would love there to be a minified output flag (through persistent configuration? hostctl config minimal)

Describe alternatives you've considered
outputting to /dev/null, but I want to see enabled/disabled profiles.

Describe the bug
I have a profile file with 23,000 lines that used to work just fine. With 1.0.0 (and now 1.0.2), hostctl no longer works.
hostctl status didn't work. I removed all profiles to start fresh and the big file would not be added --from.

To Reproduce
Steps to reproduce the behavior:

1. sudo hostctl add nsfw --from https://github.com/smhmd/dotfiles/blob/master/.config/hosts/nsfw -q
   (there's an idea. Profile files --from URLs.)

Expected behavior
hostctl to load the profile

System
OS: Linux

Additional context
Loading that profile worked in 0.10.x.

In order to have a very thorough documentation, here you have an explanation on how the docs are automatically generated and published, and how you can contribute to improve it.

Where to create/modify guides?

Markdown docs can be found on the Hugo site folder on the docs branch.

The path for the guides is: docs/content/docs/guides, there you can modify or add new content.

Automatic CLI usage docs

On the same branch there is a directory where all content is generated automatically with a cobra feature to inspect and generate markdown.
So everything inside docs/content/docs/cli-usage is auto generated and will be overwritten on each run of the workflow.

Don't manually edit content there.

What to add?

• Anything that you consider useful for other users.

• Things you struggled with and found out how to solve.

• asciinema records that show how to use any feature. see how to below.

• Whatever you think is missing to better learn to use hostctl.

How to add content?

• First open a new issue to show your intentions about what would you like to write, that way the community can add to the discussion and help.

• Then fork it and checkout the docs branch.

• Create/add/modify any content you like.

• And finally open a PR to the docs branch

• (optional pro tip) If you add the text "Closes #999" on one of your commits with issue number you opened on the first step, it would be automatically closed when the PR is merged.

How to add asciinema casts

• Check asciinema Getting started if you don't know how to record.
• Once you have a cast file, ex: my_record.cast, add it to docs/static/my_record.cast directory on your PR.
• Modify a markdown file to include the player and your cast as the following example:

---
title: Some guide with a player
description: A great guide with an asciinema player
+asciinema: true
---

Some content... 

+{{<asciinema key="my_record.cast" >}}

...More content... 

Does the framework you're using support interactivity of this sort?

I could imagine a heavy use of hostctl profiles would call for such an interface.

Is your feature request related to a problem? Please describe.
This is a great tool, as the hosts file can be a b**ch to organize! The issue I am having is that I use tools to add entries to the hosts file and (maybe I simply do not understand the tool) would like to somehow manage these entries easily. I use tools like Spybot Anti-Beacon which automatically add entries specifically to the default "hosts" file.

Describe the solution you'd like
Would like to somehow combine files into one hosts file. As stated, maybe I don't fully understand how it works. If I were to divide my hosts file into profiles, then use Anti-Beacon to update its entries, I would like to be able to add all of those new entries to the "Anti-Beacon" profile basically. If this is possible already, then disregard this.

Describe alternatives you've considered
What I've considered, as hostctl (to my knowledge) can target other hosts files easily, is to have several files for each tool and use hostctl to combine these into a "master" hosts file. This is cumbersome as it involves the swapping of hosts files (e.g if I have all Anti-Beacon entries in a 'hosts.beacon' file, when I want to update these entries I have to rename it to "hosts" and then use the tool to update the entries, rename it again to 'hosts.beacon' and use hostctl to import the new entries).

Additional context
The documentation for this tool seems (to me) inadequate as I am not entirely sure how to exactly import entries to the hosts file. I just now found how to add profiles, as the set command is not part of the "CLI Usage" documentation for some reason...

hostctl enable -p awesome amazing sublime would only enable awesome. Is there a way to batch manage profiles?

Describe the bug
Every time when run add/replace commands hostctl is adding 1 more header

##################################################################
# Content under this line is handled by hostctl. DO NOT EDIT.
##################################################################

To Reproduce
Steps to reproduce the behavior:
just run hostctl replace -f /path/of/some/project/repo/.etchosts few times

Expected behavior
don't add header if it's already exists

I need also write configuration parameters to some Linux config files such as sysctl.conf and limits.conf.
Can we add a flag such as --nohosts to disable verification?

Maps in go don't always keep same order. Change to Route map slice instead.

There is a Github Action workflow that automatically generates packages for different systems. I can only test on Linux and Windows, so I need help to test all options:

• Linux/Mac/Window binary
• deb package
• AUR package
• scoop
• Brew tap
• snap (pending add feature to work properly)

Please add comments if you have tested it any version of this list. Thanks!

UPDATE: Finally the snap build is approved to have proper permissions 🚀 !

It is outdated with samples from v0.10. It must be updated and version both files as hostctl.cast and hostctl.gif

The current state of the CLI and module is kind of beta(ish), is subject to small/big changes as I or the community finds it uses, requests features and I learn better ways of implementing the CLI with cobra.

Here are things that should be finished before reaching an stable version tag v1.0.0:

• Add a decent amount code coverage of all files in pkg directory. #48
• Refactor pkg code to expose a better API to use as module. #48
• Change semantics to have profiles as arguments instead of flag. #37 #48
• Allow to manage multiple profiles at once. Ex: hostctl disable profile1 profile2... #48
• Add mutex to save file to avoid concurrency issues. #48

NOTE: The issue is locked just to keep better track of the features that would be added. In anyways this mean you can't participate on deciding new features.
I encourage you to open new issues with any idea you have.
