7 ## Before trying out the examples: Get and build JerryScript library
9 Before getting started using the JerryScript library it should be cloned and built for a target os/…
18 $ git clone https://github.com/jerryscript-project/jerryscript.git
19 $ jerryscript/tools/build.py --builddir=$(pwd)/example_build --cmake-param="-DCMAKE_INSTALL_PREFIX=…
20 $ make -C $(pwd)/example_build install
25 In this guide we will use `pkg-config` to ease the usage of headers and libraries.
32 Test if the `pkg-config` works for JerryScript:
35 $ pkg-config --cflags --libs libjerry-core libjerry-port-default libjerry-ext libjerry-libm
40 The most basic example to test the engine is to create an `api-example-1.c` file containing the fol…
50 const jerry_char_t script[] = "var str = 'Hello, World!';";
52 bool ret_value = jerry_run_simple (script, sizeof (script) - 1, JERRY_INIT_EMPTY);
61 $ gcc api-example-1.c -o api-example-1 $(pkg-config --cflags --libs libjerry-core libjerry-port-def…
67 $ ./api-example-1
71 ## Example 2. Split engine initialization and script execution.
81 Use the following code for the `api-example-2.c` file:
91 const jerry_char_t script[] = "var str = 'Hello, World!';";
92 const jerry_length_t script_size = sizeof (script) - 1;
100 /* Run the demo script with 'eval' */
101 jerry_value_t eval_ret = jerry_eval (script,
121 $ gcc api-example-2.c -o api-example-2 $(pkg-config --cflags --libs libjerry-core libjerry-port-def…
127 $ ./api-example-2
131 ## Example 3. Split JavaScript parsing and script execution
135 - script code setup - `jerry_parse`.
136 - script execution - `jerry_run`.
138 The `api-example-3.c` file should contain the following code:
150 const jerry_char_t script[] = "var str = 'Hello, World!';";
156 …jerry_value_t parsed_code = jerry_parse (NULL, 0, script, sizeof (script) - 1, JERRY_PARSE_NO_OPTS…

208 The `api-example-4.c` file should contain the following code:
233 const jerry_char_t script[] = "print ();";
234 const jerry_length_t script_size = sizeof (script) - 1;
255 /* Release all jerry_value_t-s */
263 jerry_value_t parsed_code = jerry_parse (NULL, 0, script, script_size, JERRY_PARSE_NO_OPTS);

307 - `jerry_value_to_string`
308 - `jerry_string_to_utf8_char_buffer`
310 The `api-example-5.c` file should contain the following code:
337 …size_t copied_bytes = jerry_string_to_utf8_char_buffer (string_value, buffer, sizeof (buffer) - 1);
353 const jerry_char_t script[] = "print ('Hello from JS!');";
354 const jerry_length_t script_size = sizeof (script) - 1;
375 /* Release all jerry_value_t-s */
383 jerry_value_t parsed_code = jerry_parse (NULL, 0, script, script_size, JERRY_PARSE_NO_OPTS);

485 ## Example 7. Interaction with JavaScript environment - adding a string property
490 Use the following code as the `api-example-7.c` file:
496 #include "jerryscript-ext/handler.h"
501 const jerry_char_t script[] = "print (my_var);";
532 /* Now starting script that would output value of just initialized field */
533 jerry_value_t eval_ret = jerry_eval (script,
