Nim Community Survey 2020 Results

20 January 2021 The Nim Team

The Nim community survey 2020 has been open for one month, and we have received 769 responses - we think this is a large enough sample to draw conclusions about our users and their habits. Before we go into details, we would like to thank all the people who took the time to respond. We really appreciate the feedback!

The goal of this survey was primarily to determine how our community is using Nim, in order to better understand how we should be improving it.

Do you use Nim?

Based on the answer to this question, the respondents were divided into two groups that each received a separate set of questions.

Approximately three quarters of the respondents use Nim (31% frequently, 41% occasionally), while the remaining quarter is divided between people who never used Nim (16%) and people who stopped using Nim (11%).

Of those people who don’t use Nim, the most frequent reasons are: “Nim seems immature, not ready for production” (36%), “Nim doesn’t have libraries I need” (33%), “Nim seems too risky for production” (25%), and “Nim doesn’t have enough learning materials” (24%).

For people who stopped using Nim, the most common reasons were (answering a free-form question): lack of libraries (small and not mature ecosystem), incomplete documentation, bad editor support, compiler crashes, coworkers don’t use it, etc.

Users

We have approximately the same amount (around 40%) of new Nim users (people who started using Nim in the last 6 months) and experienced users (between 6 months and 2 years). Nim veterans (more than 2 years of Nim experience) are about 20% of our users.

A typical Nim user would be a software developer from Europe.

Besides Europe (more than half of our users), our users mostly come from North America and Asia. Almost half of our users are software developers (47%), and the next largest group are students (17%).

We have users from all age groups and all levels of programming experience, proving that Nim can be used both by beginners and veteran programmers.

Things that people like about Nim the most are: performance/speed (86%), ease of use (76%), syntax (73%), and self-contained binaries (63%).

It’s no surprise that the most used editor is VS Code, with 62% of Nim users choosing it in the survey. In the second place is Vim/Neovim (37% combined), followed by Sublime Text and Emacs (10% each).

Nim versions

We’re glad to see that the large majority of users are using the latest stable version (1.4.x).

We can partially attribute this to the mostly painless upgrade process:

Using Nim

The situation is slightly better than in 2019, but far from what we would like to see. We hope that we’ll see even larger improvements in the future. The majority of users use Nim only sporadically (25% of time or less).

Nim is mostly used for writing command-line programs and libraries, followed by automation/scripts, GUI, web services, and data processing.

The large majority of Nim users are targeting Linux, followed by Windows and macOS. Compared to 2019, we see an increase in JavaScript, Android, and iOS.

About one third of Nim users use it at work, either exclusively (7%) or from time to time (26%).

Of people who don’t use Nim at work, one third can’t use it because their company doesn’t allow it. Three quarters of people who are allowed to use Nim at work plan to use it in 2021.

People mention stability, better tooling, more third-party libraries, having to mature, and better documentation as the main areas where Nim should improve to be more accepted in their companies.

Learning Nim

Almost all of our users have read the official tutorials, and about half of them have read “Nim by Example” and/or the “Nim in Action” book. Rosetta Code examples are also a popular choice as a learning resource, followed by “Nim Basics”, “Nim Days” and “Nim Notes”.

If anyone would like to create some more learning materials for Nim (which is very high on the community priority list - see below under the “Nim in 2021 and beyond” section), the most wanted types of learning materials are code examples and written tutorials.

Nim community and contributions

Compared to 2019, we see a 20% increase of people who have already contributed to Nim! And there are almost three times as many people who haven’t contributed to Nim so far but plan to do that in the future. We’re looking forward to this :)

The most frequent reasons for not contributing (yet) are: lack of time, and lack of skill/experience.

In the past we haven’t stressed enough the importance of community donations, which is reflected in this graph: only 10% of our users have made a donation in the past. We are happy to see that two thirds of our users plan to do it in the future, which will help us to have more manpower to fix the most important bugs more promptly and work on some exciting new features.

Nim tools

We’ve asked you how satisfied you are with the Nim tooling:

Most of our users use Nimble package manager and they are very satisfied with it. Fewer users picked Choosenim as their way of installing and updating Nim, but those who did are quite satisfied with what it has to offer.

Nim doc is generally liked by those who use it, as is Nimpretty. Nimsuggest is liked a bit less than other tools (high CPU and memory consumption), but you’ll be glad to hear that our plans for 2021 include making Nimsuggest more robust, and less CPU and memory hungry.

Nim in 2021 and beyond

According to the votes, fixing compiler bugs should be our first priority: 55% of our users find it very important, with only 18% of votes for “low priority” and “current situation is ok”. We will continue to work on it, and we appreciate any community effort on this: we already have several individuals continuously helping us with fixing compiler bugs (thank you!), and we’d benefit from more.

Improving the tooling is very high on the priority list for our users (higher than in 2019), and especially for those users who use Nim professionally. We’re happy to announce that, thanks to our partnership with Status, improving the developer tooling is one of the goals for 2021.

Back in 2019 we improved the documentation of the most used standard library modules. There is still room for improvement, but we now see that more users (compared to the 2019 survey) think the current situation is ok. When it comes to learning materials, where we mostly lean on the community content (for this to improve we need your involvement!), people want to see more written tutorials and code examples.

According to respondents, fixing bugs in the existing standard library modules should be higher priority than expanding the standard library. One of the reasons that expanding the standard library is less of a priority could be that Nimble now has more than 1500 packages, adding significant functionality that is not included in the standard library.

To summarize, 2021 is the year of stabilization: our priorities will be fixing the compiler and standard library bugs, improving tooling and documentation, and improving and expanding the learning materials.
