to you to the community to the
contributors of conan center
is thank you it’s a big thank you to all
of you because this is an amazing
milestone and this is
not only about the about the 1000
recipes in a github repo
that is nothing the important
part of it is that there are thousands
and thousands of companies using conan
in production
uh in in everywhere in agriculture in
automotive healthcare finance
gaming
and these companies many many of them
which means
tens of thousands of developers and
millions of people
are using red these recipes from conan
center into their products they are
releasing it to the world this is
something that is has a huge impact i
can tell you because i work closely with
many many conan users daily i talk to
them everything and they are growing new
users are joining every day
the impact that you the community in
conan center are having in the world is
absolutely incredible
so as a
small small thing for you we wanted to
do something
and we today we are going to raffle
a nintendo switch this is if you have
contributed to conan center that means
to the conan center index github repo if
you have done a pull request
and it has been merged
you please please
enter your data into this link this link
will be posted into them
into them
uh into the zoom into the into the
youtube
uh somewhere please in the next half an
hour
enter the your data there and we will be

you and and and the main things is for
the community and the contributors but i
also want to have a award for for gay
fruit because jfrog is sponsoring the
party they are sponsoring us the conan
team they are exploring the sponsoring
the content center infrastructure that
as many of you know is not it’s not a
small one it’s a it’s a big one and also
many other things they are releasing the
artifactory communication for free so we
can use it in our companies as well and
overall they are just believing in open
source and supporting the cianci
platfast community
so thanks thanks very much jeff for for
that
and my second thank you today because
today we are talking with the
contributors
is the conan center team of course the
conan team but especially in this case
the this uh this is the core of the
conan center team the people that are
supporting you
daily
and what i love about about this team is
that they they do it greatly they are
really talented people but they are also
passionate they are fun to work with
this is uh one of the best team members
and i really wanted to say uh thank you
tim
and keep keep rocking
finally i want to share the word uh
about the future okay the past has been
amazing this mileton is is the reflect
of this past
and we have an exciting
future head we are very very close to
release our first 2.0 alpha
it will be very alpha state but it will
already implement most of the feedback
of the tribe many important changes
that have been discussed in the in the
tribe
are already there so please keep tuned
because we will be we’ll be releasing
this very very soon
what does it mean for conan center
most of the things that you will need in
conan center are being made available in
1x so for example conan 140 has many
many things that will will be available
and they will be possible to do pull
requests to content center using these
tools so
quantum center becomes prepared for the
conan two zero migration while being in
the column one x s list so please keep
tuned for these changes we will be
releasing a releasing blog posts to to
report about this
and uh yeah i i’m pretty sure i’m pretty
positive that the future and quantum
screen will be great
because uh your support and your and
your contributions are amazing and you
will be there so thanks very much
and please keep keep rocking the the
conan center
and
that’s it
thank you very much and i wanted to now
to pass the word to javier who is going
to present about the
about the
thanks very much thanks very much diego
so before we before we pass over javier
um so it’s super exciting that conan two
alpha’s coming out
um and i i think it’d be worth it what’s
your
what what are you most looking forward
to
for
for the conan 2 release because this has
been a long time in coming
yeah absolutely
i’m looking forward to reduce the number
of tickets and support tickets that we
get in github because you know what the
the integrations
uh
everything will be way more natural and
intuitive the expected behavior we are
getting rid of many legacy
we we’re talking about five years old
decisions
and now we are getting rid of them so
this will result in a much
more powerful and also intuitive uh
conan quran 2.0 and
it is expected that it will be
way more smoothly to to support and the
users of course that means uh happier
users in general so this is what i’m i’m
looking for and i’m more excited
being the user is more more happy and
more satisfied using con crazy no that’s
great and that’s that’s very confident
to
do a new release and expect the support
tickets to go down
okay so let’s um let’s add javier to
talk a bit about the demo
welcome javier hello how are you okay
i’m gonna put you in the background
diego thanks
sure thanks dial for the kind words
hi steve how are you
hey how are you doing and what are you
going to talk about today
well i think today is about
celebrating the 1000 recipes and
okay it’s a great milestone we one year
ago we we wouldn’t believe that we would
be speaking about one thousand recipes
now into two thousand twenty one at one
august we get to that number this is
really amazing
yeah no that’s a huge that’s a huge
milestone okay i’m going to put you full
screen and you can you can take it away
yes please
okay yes
said okay i’m javier
most of the people that is contributing
to conan center in the backstage
and i really need to thank all of them
as davao said it’s an incredible team
i’m very happy to work with all of them
and
of course
i need to say a big thank you to all the
contributors and also i need to join
with theo and say thank you to jfro
because
they are they are really sponsoring
conan and conan center
okay i wanted to talk to you about
my life as a as a c class plus developer
okay i’ve been a superplus developer for
more than 10 years before before joining
conan
and as many of you i suppose
this was our life
okay this is what we really like to do
we love to code during the
week we work on
work stuff and during the
the weekends we keep programming of
course don’t do it okay weekends it’s
just for rest and enjoy but we really
know the truth and the truth is that
during the weekends some of us are
trying to learn new things trying to
experiment with new libraries trying to
learn and to improve our skills
and
this was me one month ago i was trying
to look for
okay let me i will
tell the history from
from the very beginning
i was trying to i said okay i want to
show these 3d models in the in the
browser
do some
thingiverse thing okay there’s a 3d mode
and i want to do it using simpler class
okay we all know that there is a theme
called m-scripting and it should be more
or less the way it will
and i started to look for libraries
that i can use to to run something like
this okay and this will be the model
just a conan cube that danny did some
years ago
and i found this library machine library
okay this is a c plus plus library and
looking to the examples
i saw that
okay this is 3d in the web
so probably this is what i was looking
for
okay this is m script then this was
exactly the thing i wanted to do
okay i have a library i don’t need to
write it my own
then what do you usually do
okay you go to the source code to the
examples i have the tab here
and you start to check okay you navigate
the examples
you look for the one you are interested
in
which is for example okay what’s this
one
you check the c plus plus
okay not so many lines
well most of them related to
mouse controls and the draw event okay
it’s
easy i mean sorry easy example but then
you go to the cmake list
i suppose that all of you if you are
here listening to people talking about
conan and conan center probably you are
c
developers you know cmake and you know
about cement lists
and you find
the thing that we as sickle splash
developers are afraid of
this fine package
find packets okay just a couple of
libraries
but then you start to pull the thread
and
you see that it is not only those two
libraries those libraries require
other libraries and those other
libraries require other libraries and
this was more or less it
okay
magnum requires great requires sdl
version 2 which also requires a lot of
libraries then some audio libraries
opengl for of course
and as i was willing to load some 3d
model i need some plugins or extensions
to read that
that model and import it into something
that magnum can’t remember
and you say okay
it was going to be easy it was just a
library no it is 15 or 20 libraries and
you start to think
you say okay i was trying to do this
during the weekend
maybe what can you do okay you can
switch to buys
it would be a surprise a pip install and
it will probably work
maybe javascript it’s also easy they
have npm and it works
even java have its own thing
marlin you can run now and install and
it works some of them will be easier
or harder to run the series in the
browser
but when it comes
to c plus plus
you just can’t
pray
okay you just can’t clone the sorceress
and see if the rhythm helps
and
what do you do okay you just you can
give up
or you can try a different approach
and then you discover
conan center
and just to go to the web page i suppose
all of you know it conan i o conan dot
io center
and there you can search for libraries
and you see that sdl is available
hard booth is available
and more or less you start to check that
all the libraries you need for your xml
exam smart example are available
and then
you are happy again
okay you start to think
that probably it is possible probably
you will be able to build that
example in in that weekend probably just
in one afternoon if everything works
and i suppose that now is time when you
want to see
it working okay
because yes it does it works so let me
share the scenario with you
and
using conan
with conan center the only thing you
need to do
is
something like this okay you just need a
file you just need to list
the recipes you want to use okay you
need some generators some something else
but i’m not going to enter into details
here you have very good documentation
in the in the conan webpage you can
follow them you can follow the getting
started and you will know
all the secrets behind this
behind this file
and everything you need to do is just
write your regular cmake script which is
the the theme i have here
this is exactly the same file we saw in
the examples
okay the same c plus plus five
and with a simple
phonon command
like this one okay upon an install
it will retrieve recipes it will recruit
packages from their remote and the most
important thing
it will create
these files
these fine module files that we all know
are the
keystone of cmake
with these files
we know that okay if they refer to the
property include files and to the proper
libraries and everything
then it will work and it does work
okay we can build this example
in release
and we can run the example
okay it will take some time because the
cpu is busy with a streaming streaming
process but it will it will work trust
me
it was building advance okay i’m
building everything from scratch
let’s see if it
starts the application
come on
okay here it is
this is just a regular desktop
application okay this was the easy thing
we all know that okay next more or less
everything was going to work
but the great great great thing with
conan is that with exactly the same
sources exactly the same cmake file
and
more or less the same command i just
need to change a profile you can learn
about profiles in quantum documentation
okay
exactly the same
command
conan will install
the libraries for ms script and in this
example okay maybe you need to build
some library from sources that’s not a
problem conan will deal with it
but the important point is that you will
get your fine module files
pointing to the right binaries foreign
scripted
and it will work exactly the same as it
was working for the release
let me switch the configuration
let me build it
okay maybe it takes longer
and being honest this is something that
one year ago or
i think yes one year ago it was
unbelievable for me okay i couldn’t
think that writing a small example to
show a 3d model in the browser was even
possible okay it has it has been
it has built
the theme now i need to
open a server
and if i go to the browser
and enter
the address
here it is exactly the same sources
exactly the same image file
exactly almost the same command command
everything is ready for it you for me in
this case to use and i’m really really
really really happy
because this is possible now and it was
not possible before
and to be honest
i think that this is a new era for c
plus plus developer for those of us who
love
to write c plus plus code
now we can do something that
it was unbelievable
one year ago one year ago it would take
me
one week to build those 15 or 20
packages
and yes i’m very very very grateful for
all the people who make this possible
and i wonder
how how is this possible
because
i really want to thank them
yeah so
i would say
a developer like
javier
that
it’s all about the contributors
in conan center
but maybe we have people here that
is not
so familiar with the
with how common center
works
so
let me go a little bit
a little bit further and explain how
it’s
everything happening
so
yeah it’s all about the contributors but
what’s happening there so
in conan center
we have a common repository
which is called content center index
and here is
where all the interaction happens this
is where people in conan center meet to
contribute
new recipes
and the process is
fairly simple
you just have to open a pull request
with the recipe you want to
you want to have in conan center and
all the packages will be generated for
for you
so
in the repository
has had a
really great
acceptance and as you can see in the
graph
we have a good number of pull requests
every month
so
here you can see the trend that is
increasing every month so for example if
you take july we reach over the 400 pull
requests
which is something amazing for
people contributing here
and you can see more or less that the
trend is 200 pull requests every month
which is something something amazing
so
as i said
the repository has a lot of
a lot of activity
and another milestone is that we are
more than 500 contributors already so
this is what we are
why we are today here uh we are
all we all want to say a big thank you
because this is the people that are
making it
possible so
yeah it’s it’s great
so
but when you contribute to conan center
you also have
this
great feeling of people interacting in
pull requests sharing their knowledge
and you know making the recipes better
and making the c plus plus ecosystem
more usable
so
when when we started to look at the
other data uh we saw that uh reflective
there for example here in this graph you
can see that the
most of the
pull requests that are open to conan
center are actually merged we have a
very low rate of pull request that got
declined or pull requests that are that
remain open
so yeah this is great even in some
months if see in the in the chart
there are
there are pull requests
all the pull requests have been merged
so this is great and you have the
feeling that
if someone wants to contribute if
someone wants to open a new pull request
they are not going to be left behind
they are going to receive feedback in
the pull request and it will be
finally finally merged
so yeah this uh it’s a great feeling
and also here you can see
uh
people that are the top contributors to
conan center
i mean
we have
many many great people that are a
sharing and improving recipes over time
and yeah it’s great to see that huge
amount of work invested there
but
it’s not only about top contributors but
about anyone contributing to the
repository so in the chart you can see
that
also new people coming to the repository
are getting pull requests merged
so here you can see monthly pull
requests versus monthly unit
contributions and of course the pull
request trend is
great
but also the the unique contributors
every month is increasingly steadily so
this is a a huge thing for uh for a
community like
the conan center one
and and this is great uh to see that
that
this is working
but
yeah let me
let me go a little bit farther and see
that uh
behind the scenes uh
is more complex than it looks like so
this is what happens in the ripple but
behind the scenes there is a whole
system taking care of building the
the packages
so
here you can see uh simplify the diagram
of what is happening there
so
as some of you may know we are running
the wheel service on top of jenkins and
on top of artifactory
and
basically the flow is whenever a pull
request is open
and or a new commit is done it triggers
the new build
and for every
new er
and for every build we are doing a
couple of things so
uh for example we have delicate hook
checks that are taking care of the of
the quality of the recipes
we also calculate the different package
ideas that
will generate
the the different profiles that we
generate a different package id sorry
and finally those packages are built and
uploaded to a dedicated repository in
artifactory along with some useful
metadata that we are collecting
also the feedback during this build
process
is shared a
with a content center with a well-known
content center bot for for the community
that is the one providing feedback in
the pull request comments
in the bills and they are and it’s also
collecting a summary of the packages
that were generated or the packages that
that failed
and finally
when the
when the pull request is finally
reviewed and merged
the packages go through a different
process that we
call it a promotion
that is just coping packages from one
repository to another in artifactory
which is a really
a really great thing because we don’t
have to spend time
uh
downloading up and uploading packages
again
so
in fact
we are relying entirely in in
artifactory so here
we can we want i wanted to show you some
of the things that we are storing in
artifactory you can see in the in the
list the most
the the
sorry the reference that have the
more the most recipe revisions
uh and besides the huge milestone of
having quite a little bit more of
1000 recipes you can see there that we
have
a good number of ref references complete
references i mean the
libraries with the with the persian
altogether we have 216
600 packages uh there and
and also the revision so
artifactory is actually serving more
than
50 terabytes of data
that comes mainly from the from the
binaries generated
and yeah and you can see we got a almost
10 000 recipe revisions
each of them
with
more than 80 packages average uh
so if this is this is great and our
artifactory is actually serving a huge
amount of of data uh for conan center
and and for everyone
available for everyone just
with a conan current install command
and also to give you some idea about it
here we started collecting
recently some trends about the the
the data transfer that we are serving
from artifactory and here you can see a
graph
with the oil remote
and the
the one from bing tray and and the other
one and it was a great thing to see that
the
the data was actually reflecting uh what
we expected
so
yeah you see here that
the
the conan center started to to
got more data transfer than the old one
and
and it was uh great to to see say people
moving
to this
to disconnect center with new remote and
it’s actually
amazing to to see how artifactory is
actually serving all this amount of data
so
as diego said in the in the introduction
of
of the talk
there is uh
also people taking care of this system
running and i wanted to
also to thank you the the jfrock team
there we are
there are many people
many people taking care of this system
and and taking care that is running
almost around the clock so i wanted to
also to join with a thank you
to jfrock and and to the people here
that
you know it’s a group of amazing people
that
that we are
we are keeping the system running
so yeah
now let me hand over again to my
colleague javier because i think
there is
something else we want to tell you
yes besides all the people that is
making possible this system in the
united states maybe you know some of us
in github because we are
all the day every day they’re trying to
help
you and as you help us with our pull
requests
that’s not all
okay
because what we have built is not only a
system that process pull requests and
eventually merge the packages
what we have here is not only a great
team of people working in conan center
what we have here is not just jfro
a sponsoring this effort
we have here also
the work of many of you not only in the
recipes
but also writing hooks for example those
little snippets that help us to cook
those recipes in the worst best way
possible
that help us to validate
every little detail from recipes
that’s not all on top of conan center
there are some bots that you the
community have developed there are bots
that take care of the documentation
okay
as you know there are also
a boat that detects possible conflicting
recipes and post a message in the tool
request hey have a look to the other
pull request because it is modifying the
same recipe that’s great
there are also a bot which is
notifying about the pull requests that
are ready to be reviewed i mean those
pull requests that have built all the
packages successfully and they only need
some manual intervention to review and
approve those packages so they can get
merged into into conan center
there are also bots that take care of
notification when a new release of a
library is released
and they create pull requests for those
new releases all automatically so this
is this is really great
and when you have a look to the pull
request and you start to follow links
this is not all that happens there is
something
i’m really really really happy that it
is happening and it’s and it is when you
follow links sometimes you get
to repositories where you see that
library authors are taking patches that
were developed
in the context of content center and
they have taken those patches and
applying them to their libraries
patches to the sources and also of
course patches to the to the build
system
this is really amazing we are all of us
are contributing back
to those library authors that are making
everything possible from the very
beginning
and it is great to see that
those authors
see some value in conan center because
conan center helps them
to solve their
the library is now in a place in a web
page that is aggregating
like c plus plus libraries and you can
use to search and find
libraries that you were not aware of
so this is also great and of course
our experience our pull request is
helping the conan client to be every day
a better tool for c plus plus developers
we detect bugs we
suggest new features we contribute with
examples that help conan to be
the best package manager out there
and this is great i think i really think
we are building a virtual cycle
okay we are creating a platform and we
are already in that point where
we have enough recipes so people think
that conan center is something useful
and as they think it is something useful
they contribute with more recipes and
this is
exactly what we really need and what we
really want
and
to be honest i think that it is of
course it is not possible within jfrog
it is not possible without some work of
some people the great thing we have in
conan
but it is not possible without you
and this is the message from this talk
this is
because you are there you are
contributing to recipes and we really
think
we are already a conan center community
and what’s next 2000 recipes i don’t
know the sky is the limit
so now i will
love it danny join us again
and
steve you can pop up as well
hey no that was awesome great
presentation both of you and i’m i’m
very excited how do i write my own bot
yeah you actually will have to
ask the people in the community they are
doing amazing things with the with the
bots there
now that’s great um excellent excellent
job and it’s great to see all the the
hard work which the
um
you guys and the whole conan community
are putting into making it a better a
better ecosystem and easier to use
cnc plus plus libraries
yes i think that’s the
the biggest achievement of conan and
conan center to make c plus plus
ecosystem
a better place
cool that’s great and um
i think that the next thing we wanted to
do was to
have a panel with some folks from the
conan community
um
so i’m gonna i’m gonna ask some
additional folks to
to join us thanks thanks danny i’m gonna
i’m gonna drop you
yeah you don’t go too far
okay and now we’re gonna add
julian
and chris
welcome how are you guys doing
very good
hello hello hi
awesome and um so what we’re gonna what
we’re gonna do for this panel is um
we we really want this to be interactive
with folks watching the stream
so if you can
ask questions um preferably on the on
the conan slack if you’re on the conan
slack so
feel free to just ask them um
conan the cppslack
or you can also ask on the youtube
stream and we’ll we’ll try to pull in
comments if you’re on the youtube stream
only and you wanna
you wanna ask some things from
from folks who are on the panel here
and i think this is also a great
opportunity just to just kind of
appreciate what folks are doing with
conan how they’re using it and for us to
get good feedback about conan as well
because we want to continue
improving conan we want to make it a
better resource for for the community
make it work better have improvements in
conan 2 which are going to value the
community and the only way we know this
is by folks in the community
um helping us out so let’s let’s quickly
do a round of
self intros so
um i think you you just finished
presenting javier but why don’t you why
don’t you introduce yourself a little
more fully
well
i mean i was a simpler class developer
for a long long time and to be honest i
really quit my previous year because
in order to continue working as a
superstars developer i needed a package
manager and that’s the
one the main reason i joined jfrog
to develop conan
and we are building it
yeah i think you’re in the right place
[Laughter]
okay and maybe you want to go next
julian
hello i am william and
i used to be a simple sports developer
like a hugger and for many many years we
had problems with
the software management pack management
and i used to
create a bash script like i
i wrote in the chat
to build out my independence but it
looked like two weeks and of course only
works for a specific scenario for linux
for example and we have the similar
scripts on batch for windows
when uh
i know
and after that uh i knew kona
and the fact management was
was uh changed mind about the some of
the problems right to this plus plus
cool i like your thousand recipes on the
whiteboard in the background
very colorful
okay and last but not least chris um how
are you doing you want to enter yourself
introduce yes so i have been programming
in c plus since i was a p little kid in
school started with programming on
robots and i worked all the way up to
doing cloud apis restful xero trust
security
and i am also a former c-plus plus
developer there seems to be a trend on
this chat today
i also had this same experience trying
to build restful micro api services the
number of dependencies was immense and i
absolutely needed a package manager and
it’s part of the reason why i’ve been so
passionate about contributing to conan
on my spare time
cool awesome thanks chris
okay so we we actually have some some
good um questions coming up on the
youtube chat so um devere
um asked a couple questions um which
he’s curious about so one thing he was
wondering is statistics of library
authors adopting conan as the official
way to consume their package so do we
know
do we know how many library authors are
actually starting to look at conan as a
better way to distribute their packages
um
that’s a hard question and
to be honest we don’t have
that number we would love to we know
that there is people that is already
using just conan for example today i saw
a tweet where
there was a 3d engine that he moved
from cmake to conan he was just using
conan install and gonna build
which was okay under the
under the
the conan call of course probably it was
running cmake
but
also
i mean i mean there is there are people
but
we don’t know how many this is something
we would really want to know
but
we cannot know what people is doing in
their own repositories
yeah and i mean hopefully it gets to the
point um just like in the other
languages you you pointed out where it’s
the default that you
you use a package manager like conan to
do your releases
um i think that’s pretty much expected
that any any python npm or java package
you use just just by default uses a um a
package manager the one of vira’s second
questions was um how an author can
automate releasing new version so how
how easy is if i’m an open source author
to
just automate um pushing new packages
and having them built by conan center
i don’t want to take all the questions i
think
prince also
know about this one probably right
because
it is about the the boat i commented
there is a boat that is monitoring new
releases of libraries and submitting
automatically a pull request with the
library i think that the author of that
vote is in the youtube channel
because yeah yeah actually he replied as
well to hear her and talked about the
bot i think it’s probably him although i
can’t read cyrillic so the name is is
unpronounceable for me
so this is something we haven’t written
okay this is not our work it’s a
contribution
and it is just monitoring new releases
and submitting the
required changes so conan center will
trigger the full request to contribute
those packages those new packages to
connect center
so just know it is possible it is easy
because
given how conan center works you just
need to modify a file which is easily
modified
with a script
so it is
a piece of cake i mean and if anyone
wants to do it just open an issue in
conan center index and we will help him
also croydon created a specific box to
operate the dependency receipt so from
time to time if you use bing crafters
depository you’ll see new definitions to
be updated by his his bot
there are more bots actually running
there in quantum centralities created by
the community eriki also created a
specific part which it takes uh
conflicts in between peers let’s say you
open uh
a bumpy temperance for a specific
package
another person creating our specific apr
for the same recipe so that bot will
identify and notify both users
cool that’s awesome um yeah so it sounds
like it’s it’s quite easy to
go ahead i think that now that we are
talking about bots i really want to ask
chris
because you wrote a really cool boat
maybe you can tell us all your
your work
for that what but
i would love to talk about it so i’m
the author of the pull request ready for
review bonds
and it monitors the github api and it
runs every hour and it checks the status
of all
the pull requests that are open
and if you go into our documentation
inside the review procedure you’ll find
some of the criteria that it takes so
the build has to be passing
it needs to have three reviews
uh one of the conan team and two
community reviews will get it
so the bot will go through and look at
all the open floor requests and check
each one of them to see where it’s at
and it’ll even add work pull requests
that have no reviews so the new ones
that get opened will also get flagged
and it makes it a really easy spot for
the community to go and find the status
of all the pogerfest that are open and
which ones need the most attention
yeah
your body is
really cool and all the graphics and the
statistics you post in that ecu i really
recommend all of all of our attendees to
to go there and have a look to that
to that really great piece of software
there’s a
two beautiful graphs at the bottom one
is open versus merge the other one is
timing review and you can actually see
like live trends about how fast or how
slow some days were moving about adding
pull requests
but the overall uh like in one of javier
and danny’s graphs there was a
number of clothes is actually incredibly
small which is really nice almost every
single poor list will get attention uh
it’s very rare that someone will close
the pull request without any comments
which i thought was absolutely excellent
for
that community strength that we have
actually i prefer to use your boss
instead of reading my embellish when i
receive a review request and
yeah because it’s more centralized
[Music]
you exactly nailed my motivation for
adding about uh
trying to keep up with all of our emails
we have hundreds and hundreds of pull
requests every month and trying to keep
up with all of them it’s a quite
difficult time but
hopefully uh it makes all of our lives
better having bots like this
i think usually i receive more than 100
emails every day about it right to
quantum communities so that issue in the
bottom
makes my life much easier
cool that’s that’s awesome and that’s a
great contribution back to the the conan
community so so thanks chris for
for being an early adopter of conan and
supporting the conan community so we
talked a bit about the pull request
workflow and like how
how to automate that and how to
how to make that easy to use
um
i i think are there other um
any other aspects of conan center which
are worth highlighting for the for the
audience that they should be taking
advantage of either as a library author
or as a as an end user
i would almost argue the platform
support uh one of the things that uh
many c plus projects
uh tend to be a little bit weaker on is
supporting a diversity of platforms
and in the conan community
uh like javier’s example with edmondson
script sdk trying to make web technology
versus c plus projects
making sure they’re portable to all
different platforms is
something that i’ve really enjoyed
getting to learn and work on more and
more
yeah and you get to do all the hard work
on the on the back end to make sure all
those platforms actually build
and we would love to have more platforms
but it’s always possible not always easy
and
it requires always more and more
resources
yeah so maybe for for behind the scenes
on on conan center what is it
what does it take to to build the same
library on multiple platforms
like what what’s the what’s the back end
process which we’re using
well
okay i can do it
we are right now we are building for
four different platforms okay we are
building for windows we are building
four linux and we are building for macos
and also for m1 apple and one
okay
basically for linux we just use docker
containers we build
different versions of gcc and different
version of clan which is why we have so
many packages
we also build in windows for visual
studio 2017 and 2019 and for sure once
it is released we will
build binaries for 2022
and in mac we use
max servers
that was
nice before
and for mac we will use max servers
to build natively to the
regular mac i mean to 64 map and then we
cross build in that machine to apple and
one
so we are not only supporting
more platform we are also testing that
recipes work for some
cross building scenario which i think
it’s also very valuable for recipes
sometimes uh we we find some some
problems with the brush we they don’t
are not compatible with some platforms
or compilers
and not even the author knows about
it’s covered some bugs let’s say from
some price when building all these
cool serious
even able to help to
find bugs and projects on different
platforms where they can’t easily build
it themselves
contribute patches upstream with
modification to the build system so it
is possible to build for those platforms
that’s
cool that’s awesome
and um what what sort of what sort of
recipes have have folks on this panel
ridden themselves anything cool
i think uh
[Music]
i apologize you can’t scream yulin would
have some very good uh examples i know
he’s had some really fun
pr’s recently
well i’m proud of
for this talk i started
almost two months ago during my holidays
to be honest okay i shouldn’t do it but
i did it
and i just started to write the recipes
for this magnum library the mac moon
integration magnum extras magnum plugins
and everything related to the library
some patches for stl too and also
another great great contributor helped
me with lots of recipes
he was
made we are i’m sure that everyone
know him
if they have visited the repository so
we were i mean like working together to
bring that recipe and all its
dependencies to connect something and it
was
a really great process
yeah so you’re actually um
following your bad advice to work
weekends and holidays
but that’s that’s when you’re most
productive because you don’t you don’t
get interrupted
um although i think i think we’ve we’ve
increased the productivity of the um the
whole developer community today because
apparently our conan
1000 recipes event is so popular it took
down slack slack’s not responding today
either very well
i would say slack is the the number one
um risk to developer productivity you
get constantly
interrupted by folks um
when you’re trying to do stuff
so
um for folks who might want to get
started with
with code and center what advice can you
give to a to a new contributor
i would say read the documentation first
but
because all the steps uh there are there
but they are very welcome to do
this the
c cp lengthy is lack
and also there is a score the
inclusivity
people are really friendly there so if
you ask there
they will have to with their first
receipt
for many times i i see people asking for
help for the first contribution they are
and of people helping
we all know the challenges of building c
plus plus i i’d recommend starting with
a header only library that you’re using
and uh get used to working with writing
the recipes and once you get your head
wrapped around the the workflow conan
it’s very easy to start adding more
complicated projects that
are google cloud apis or rust and dates
that
get done greatly from
yeah we have some good examples that we
separated on the documentation for the
first contribution
which are make easier don’t try to use
receipts as base like for example boost
or poco they are crazy to understand
try something very
simple but also i will say that i mean
this is not about creating recipes for
conan center this is about creating
recipes for kona
so you don’t
need to look only to conan center
documentation you can have a look to all
the common documentation to the connect
trainings
and several videos that are out there
where you can learn to write recipes and
those recipes are the ones we are using
in column center i mean there is nothing
different in conan center
this is
cool and um i think also something which
we we talked about and referred to in
the stream as um
members of the conan tribe and you’re
you’re you’re a member of the conan
tribe chris
um so besides besides the cool hoodie
which you apparently have in your
background what what other reasons did
you did you decide to join the the conan
tribe and help out
so
as conan has been growing and i’ve been
using it more i got to adopt it in my
former job some of my colleagues ended
up picking up on conan and using it in
their companies as well and it’s really
been
great to see its strengths but there’s
also a few spots that
could have been improved and
one of the things that i absolutely
loved was the opportunity to be a part
of the community part of the tribe to
actually help improve the version too
and there’s some really key things that
are going to be coming out like
immutable recipes which is going to be a
godsaver for most of us
having to be able to catch multiple
religions too is going to be just a
delight
and i’m sure there’s more features that
are going to get sneaked in before the
2.0 release gets dropped so
being able to contribute back and help
give our feedback as community members
is just
greatly appreciated to the whole cloning
team
awesome
all right thanks a lot chris for being a
valued conan user and member of the
tribe and for joining us for the panel
um javier julian um thanks for making
conan a great and conan center a great
system for the cnc plus plus community
and i would like to invite back up diego
so um i gotta say goodbye to all our
panelists
thanks very much
i appreciate all the answers to
questions
and thanks for joining our conan 1000
recipes events
and welcome back diego
hey hello
so um it was awesome to see the all the
hard work the teams put in
um
to see all of the
the huge milestone of reaching a
thousand recipes
and i think one thing which came across
very strongly was the
the community spirit so i think you
um
you’ve done a great job with conan and
with the community to build something
which i think the whole community is
quite proud of so
yeah i think there is a common
denominator here i
i was also a super fast developer and it
seems that most of us come come from the
pain of suffering this and we all of all
of us we want to to have this fixed and
this is the spirit we are just basically
working together it’s not they and us
and everything is just a team
trying to improve the situation and
that’s that’s great
awesome
so um we’re we’re coming to a close for
a thousand recipes event and we have a
winner
for our nintendo switch raffle
um so we’re pleased to announce that
harold ashitz
is the winner of the um the nintendo
switch thanks harold
for being a
awesome recipe contributor
so it’s great to have members of the
conan community who are building recipes
and helping to support the growth of
conan center um we hope you enjoy the
new nintendo switch harold or or have
kids who will will enjoy it as whack as
well don’t don’t get too distracted by
video games we need more recipes
we need to get up to two thousand
um
but it’s it’s awesome congratulations
and i think this is a small way which we
can
um reward and celebrate the the
contributions which the community is
making
to conan center and make it a
um a better ecosystem and a better place
to be able to get the libraries and
easily develop cnc plus applications
okay so i will give you the
last word diego for the conan 1000
recipes event
well uh
then to
to end this this
event
there’s only one word i can say is is
thank you
there is nothing better to
to say that and i’m looking forward for
another two years or five years of
working together with this amazing
community
because this is what really fulfills me
this is this is the best job experience
i’ve ever had and i’m i’m really
enjoying it so please community keep
rocking and we will be and we will keep
rocking with you
cool all right thanks everybody and
here’s to 2 000 recipes in the future
so congratulations on reaching the
milestone
and um thanks for the whole conan
community for joining us for this
broadcast
thank you
