Because no-code/low-code needs open-source libraries!
Models can be imported into Summit as plaintext using the import feature.
This repo hosts models built using Summit Event Language (SEL), which can be uploaded/imported to Summit. We recently began the work of turning SEL into a text-based language. Editing SEL without needing to use the IDE hosted at usesummit.com is the first step, as it broadens access, makes SEL faster to write, and opens up opportunities for AI to contribute, such as our GPT for learning SEL.
Our short-term plan is to still require use of the interpreter we host at usesummit.com in order to run these models, while offering a generous pay-as-you-go tier for no-code/low-code makers.
If you're reading this, you likely either work at Summit or you are a close friend or supporter. Thanks for being here! We still have a lot to do.
You are strongly encouraged to read our docs on learning Summit!
SEL is a declarative langage (hence all the = signs) that allows makers to chain together building blocks ("events") using arrows -> called "routes". As an abstraction of Python, it removes a lot of the heavy-lifting and tedium -- the hurdles that rob the joy out of coding a tiny script, plugin, or extension that creates value. SEL solves this by being a quick, fun, powerful, and complementary tool to platforms like Make, Zapier, and Glide.
To learn more, this page does a good job of explaining.
What you see in Summit when you build and host a model is an interface (canvas-based IDE) to create and connect the expressions of a model.
The documentation for the full library of SEL expressions (event types, conditionals, constants, etc.) can be found in our Technical Documentation.
Since much of the work to wrap and define an model is handled on usesummit.com as part of the IDE, the text-based version of SEL (.sel) has an expanded set of rules and syntax that must be explicitly declared in order to create a working model. Namely:
- Events may be declared/created using the event title in double quotes
"followed by a:and then a SEL expression. - Events may be connected through routes drawn using
->. - Metrics may be defined using
%at the beginning of a line. - Any line starting with
#is a comment with the exception of#! - The hashbang
#!is used to specify a version of SEL.
Example:
#!/usesummit/sel/0.1a
# Define some events with SEL expressions after the :
"a": = 2
"b": * 5
"c": =Response("total")
# Draw the flow using ->
"a" -> "b" -> "c"
When uploaded to Summit, this will be turned into an model with an API that calculates the value 10 and returns a response object containing a data attribute: "total": 10.
Some features of the language are not yet supported in .sel notation. Namely:
- If you're building a simulation (not a data transformation), to have an event recur, you must use an
Every()event (no direct setting on individual events).
We are still very much in the alpha phase. The most useful things at the moment:
- Request access to Summit at usesummit.com and let us know you'd like to contribute
- Sponsor this project!
