Example of Vely code

Query table "employees" and write result into a string and then write string to a file and to output. The code below is converted into pure C, compiled and linked into a native executable. You can run it both as a daemon (a background service process) or from the command line.

void list_employees() {
    out-header default

    char *header = make_header(); // write any C code
    p-out header

    // Create report in outmsg string and fill it with database query result
    write-string define outmsg
        // Get data from the database
        run-query#get_emp@db="select name, salary from employees order by name" output name, salary
           @Name: <<query-result#get_emp, name>>
           @Salary: <<query-result#get_emp, salary>>

    // Write report to a file
    write-file "employees" from outmsg status define st
    if (st<0) {
        @Error in writing file (<<pf-out "%lld", st>>)
    } else {
        p-out outmsg

The code was highlighted with Vely's syntax_highlighting plugin for vim.
