Sample Catalogues

614 working apps, in three repositories. Every one is a single ABAP class that compiles, renders, and is downported to three releases — so a sample is never a fragment you have to trust, it is an app you can pull and run.

The three answer three different questions. Picking the wrong one costs more time than reading this page.

		you are asking
samples	152	has somebody already built this pattern? — value help, navigation between apps, trees, tables, timers, file up- and download. Runs on a bare abap2UI5 install.
samples-controls	430	how is this UI5 control expressed in ABAP? — the UI5 demo kit, rebuilt control by control, grouped by library.
samples-stack	32	how do I reach my system from an app? — OData, RAP, APC, MIME, the Fiori Launchpad. Each needs something the framework alone does not give you.

Start with samples if you are learning abap2UI5, with samples-controls if you know which control you want, and with samples-stack only when the app has to talk to something in your system.

The pages have the same shape on purpose

Every row of every catalogue reads the same way:

sap.m.Breadcrumbs Breadcrumbs is useful for displaying link hierarchy _{breadcrumbs sap.m breadcrumb trail separator link hbox label select}

The title says which sample it is, the sentence says what it shows, and the small type are the words to search the page for — the terms somebody would type who does not yet know the sample exists. Ctrl+F on any of the three pages is a real search, not a scroll.

None of it is written on the page. All three lines live on the class, as its abapGit short text and two comment lines above CLASS … DEFINITION:

" @keywords f4 search help suggestion input dialog select
" @summary The value help, both halves: suggestions while typing and the F4 dialog behind the field.
CLASS z2ui5_cl_smp_app_009 DEFINITION PUBLIC.

The catalogues are generated from those lines, and each repository refuses a sample that is missing one. So a page can never describe a sample differently from the class it links to — and a search engine that drops you into the class gives you the same sentence the catalogue would have.

For AI agents

The same three catalogues are queryable through the MCP server — the examples tool searches all of them at once and answers with a repository, a class name and a path to read, never with a copied snippet:

examples { query: "value help f4" }
examples { query: "wizard", repo: "samples-controls" }

The neighbouring question — can abap2UI5 express this UI5 feature at all — is the capabilities tool, out of samples-controls' CAPABILITIES.md. Neither answers the other: a control being expressible says nothing about how an app that uses it is put together.

Running one

Install abap2UI5, pull the repository with abapGit, then start any class by name:

<your endpoint>?app_start=Z2UI5_CL_SMP_APP_009

Each repository also ships an overview app that lists its own samples with a search box, so once the repository is in your system you do not need the page here at all.
