This reverts commit 614fc2fcce0e9ae0bcfdc6e08d3c4bac846d02a8.

I'm going to move (again) from GH to my own instance of gitea. This
script does the migration for me.

For the python tools, we need the python runtime to be available. For
this we need to specify the dependencies in `propagatedBuildInputs`.
The same is true for flamegraph and perf.
|
|
I don't want to inline shell scripts inside nix configuration, as it
prevents me to use `shellcheck` to validate them for example.
The script is now moved into the tool directory, and is a tiny bit more
flexible, so that I can run it as my own user.
|

It's been moved to its own repository at

This tool helps to keep only the branches that are relevant: the ones
that have not been merged yet into the main branch on the principal
remote repository.

The tool can calculate some stats about authors in a git repository. It
computes the number of lines that are authored by authors at a given
revision (HEAD by default), and the number of commits.
|
|
This is a simple script, there's no benefit in having this in go. Having
it Python makes it easier to extend with panda or other libraries in the
future if I need more statistics too.
|
|
It's back at https://github.com/fcuny/govanity

|
No need to do this with Go, a python script is fine.
We also don't need to set shell aliases for this: when we install the
tool, we can create symbolic links to `ip2int` and `int2ip`.

naersk makes it simple to build rust project in nix.
For this to work, `mkSystem` and `mkHomeManagerConfiguration` needs to
pass naersk to my overlays.
I dropped the support to run the tools with `nix run .#tools...`: I
don't use this in practice and it's not making things simpler.
I dropped `nix-linter` from the check, it's reporting many errors
without helping me to fix them.
|
|
I'll go and refactor correctly and properly the support for rust
packages, this is not working and I'm doing something stupid.
|
|
I can now run `nix build .#tools.sendsms` to build the tool, or get it
deployed on a machine.

This is a new tool to send SMS via Twilio's API. For now it supports a
single subcommand: reboot. Using that subcommand, a SMS will be send
with the name of the host and the IP address for the defined network
interface. This is useful to be notified when one of my machine reboot,
and what's the IP for the main interface (this is useful since my ISP
does not provide a static IP).

This test does an HTTP request to ensure the URL for the repository does
not return an error.
The test tries first to do a DNS resolution to see if we have network
access. When we build the binary in the nix sandbox we don't have
network access, so we don't want to fail in this situation, we only want
to skip.
The test is going to be run before we do a deployment.

Add a Makefile to install the binary in GOPATH and the unit file for the

|
|
As I want the scrobbler to be started automatically when I log into my
session, the easiest way to do this is by having a systemd unit file
that I run for my own user.
The unit expects that the binary for the scrobbler is under my $GOPATH,
which is hard coded for now. We also ensure that the binary exists
before starting the unit.
We harness the service with a number of directives.

If the status of the player is "stop", we don't have a new song to

With this information, in the future, we will be able to sum up how long

The program needs two arguments: the mpd host and port, which can be
passed as flags (default is to use the local instance of mpd).
We store the database in `XDG_CONFIG_HOME/mpd-scrobbler`, and we create
the path if needed.
|
|
To compare the current attributes with the current record, we can use
the helper `EqualAttrs` which will tell us if we need to create a new
record or not.
|
|
|
|
When creating a scrobbler, we provide the path to the database. The
scrobbler then get a handler to the database.
When a new record is created, we persist it to the database using the
`save` function.
|
|
When we create a new record, let's capture when this was created.
|
|
We want to persist the records in a database, so we can extract
statistics and an history.
The module for the database is straightforward: it opens the database if
it exists and return an handler to it. If the database does not exists,
we create it and we create the only table we need (records).

Add a function to run the scrobbler, which takes care of creating a new

This will simplify the interface for the caller, as all they really care
about is: create the scrobbler, close it when we're done, and collect
songs information while we listen to our music.
|
|
|
|
Let's close both the watcher and the client, instead of leaking this
interface to the user.
|
|
|
|
When we receive an event from the player, we look if the song is
different from the previous one, and we create a new record if that's
the case. If the song is similar, there's nothing to do.

The tool "scrobbler" then wait for new events and display songs
