8 | Creating components for [shiny](https://shiny.rstudio.com) inspired by [Vue](https://vuejs.org/)
9 |
10 |
11 |
12 | It tackles three "issues" with Shiny modules:
13 |
14 | 1. Generating scoped (namespaced) CSS and JavaScript code.
15 | 2. Places all the code for a module in a single file.
16 | 3. Binds CSS, and JavaScript of a module to it
17 |
18 | This is inspired from Vue where one defines a component in a single file.
19 |
20 | ```vue
21 |
25 |
26 |
27 |
28 |
29 |
30 |
35 | ```
36 |
37 | Where the file includes the style, script, and template.
38 | We reproduce the same with R with the addition of the server component.
39 |
40 | ## Installation
41 |
42 | You can install the development version of component from [GitHub](https://github.com/) with:
43 |
44 | ``` r
45 | # install.packages("remotes")
46 | remotes::install_github("devOpifex/component")
47 | ```
48 |
49 | ## Create
50 |
51 | From a package (see [lerprechaun](https://leprechaun.opifex.org) or
52 | [golem](https://thinkr-open.github.io/golem/)), create a component.
53 |
54 | ``` r
55 | # create a component
56 | # give it a name
57 | component::create("test")
58 | ```
59 |
60 | This creates a new file in `R/` named `component-test.R`.
61 |
62 | Components generate code via `devtools::document()` (more on that later)
63 | add the roxygen2 roclet to your `DESCRIPTION`, e.g.:
64 |
65 | ```
66 | Roxygen: list(markdown = TRUE, roclets = c("collate", "namespace", "rd", "component::roclet_component"))
67 | ```
68 |
69 | So `create()` creates the component file but `devtools::document()` generates
70 | the usable version of the component.
71 |
72 | ```r
73 | component::create() => `component-.R` => devtools::document() => `component-generated-.R`
74 | ```
75 |
76 | ## Component Anatomy
77 |
78 | The default component as created by `component::create()` looks something like the code below
79 | (`R/component-test.R`).
80 |
81 | ```r
82 | #' @component test
83 | NULL
84 |
85 | #' test javascript
86 | #'
87 | #' test javascript component.
88 | #'
89 | #' @param ... Any other argument.
90 | #'
91 | #' @keywords internal
92 | .test_javascript <- \(...) {
93 | "$('{{class red}}').on('mouseenter', (e) => {
94 | $(e.target).toggleClass('{{ns red}}');
95 | })"
96 | }
97 |
98 | #' test css
99 | #'
100 | #' test css component.
101 | #'
102 | #' @param ... Any other argument.
103 | #'
104 | #' @keywords internal
105 | .test_css <- \(...) {
106 | c(
107 | "{{class red}}{color:red;}",
108 | "h1{font-weight: bold;}"
109 | )
110 | }
111 |
112 | #' test ui
113 | #'
114 | #' test UI component.
115 | #'
116 | #' @param ns Shiny's namespace function.
117 | #' @param ... Any other argument.
118 | #'
119 | #' @keywords internal
120 | .test_ui <- \(ns, ...) {
121 | shiny::div(
122 | shiny::h1("Component", class = ns("red")),
123 | plotOutput(ns("plot"))
124 | )
125 | }
126 |
127 | #' test server
128 | #'
129 | #' test server component.
130 | #'
131 | #' @param input,output,session Arguments passed from mdoule's server.
132 | #' @param ... Any other argument.
133 | #'
134 | #' @keywords internal
135 | .test_server <- \(input, output, session, ...) {
136 | output$plot <- shiny::renderPlot(plot(stats::runif(200)))
137 | }
138 | ```
139 |
140 | ### Component tag
141 |
142 | The `@component` tag indicates the name of the component,
143 | in this example `test`.
144 | This tells component which functions to scan for:
145 |
146 | - `._javascript`
147 | - `._css`
148 | - `._server`
149 | - `._ui`
150 |
151 | ### JavaScript and CSS
152 |
153 | The `.test_javascript` and `.test_css` functions are used to generate
154 | scoped code.
155 |
156 | - `class`: transforms `{{ class red }}` into `.namespace-red`
157 | - `id`: transforms `{{ id red }}` into `#namespace-red`
158 | - `ns`: transforms `{{ ns red }}` into `namespace-red`
159 | - `json`: transforms `{{ json letters[1:2] }}` into `['a', 'b']`
160 | - You may still use `{{ x }}` in which case it will evaluate `x`
161 | (passed `*ui` or `*server` function).
162 |
163 | These functions should return a character vector of length one or more.
164 |
165 | The CSS is minified using [sass](https://github.com/rstudio/sass/), if you have
166 | [uglifyjs](https://www.npmjs.com/package/uglify-js) installed
167 | it is used to minify the JavaScript otherwise it is not
168 | (install it with `npm install uglify-js -g`).
169 |
170 | ### UI and Server
171 |
172 | Almost identical to the UI and server functions of a shiny module
173 |
174 | ### How to use
175 |
176 | The created template __cannot__ be used as-is, by documenting the code with
177 | `devtools::document()` we create a new file (`R/component-generated-.R`)
178 | which contains:
179 |
180 | - `_ui`
181 | - `_server`
182 |
183 | In this example, `test_ui`, and `server_ui`.
184 |
185 | These are the functions that one should use in the application.
186 | Always work on/edit the functions starting with a dot (e.g.: `.test_ui`),
187 | as the generated files get regenerated at every `devtools::document()` call.
188 |
189 | Example based on the abose "test" component, after running `devtools::document()`.
190 |
191 | ```r
192 | library(shiny)
193 |
194 | ui <- fluidPage(
195 | title = "Test",
196 | test_ui("test")
197 | )
198 |
199 | server <- function(...){
200 | test_server("test")
201 | }
202 |
203 | shinyApp(ui, server)
204 | ```
205 |
206 | ## Example
207 |
208 | Here is the classic counter example but scoped and using JavaScript only.
209 |
210 | ```r
211 | #' @component counter
212 | NULL
213 |
214 | #' counter javascript
215 | #'
216 | #' counter javascript component.
217 | #'
218 | #' @param ... Any other argument.
219 | #'
220 | #' @keywords internal
221 | .counter_javascript <- \(...) {
222 | "$(() => {
223 | let index = 0;
224 | $('{{id button}}').on('click', (e) => {
225 | index++;
226 | $('{{id output}}').html(index);
227 | $('{{id output}}').toggleClass('{{ns criminal}}');
228 | })
229 | })"
230 | }
231 |
232 | #' counter css
233 | #'
234 | #' counter css component.
235 | #'
236 | #' @param ... Any other argument.
237 | #'
238 | #' @keywords internal
239 | .counter_css <- \(...) {
240 | "{{class criminal}}{
241 | color: {{color}};
242 | font-weight: bold;
243 | }"
244 | }
245 |
246 | #' counter ui
247 | #'
248 | #' counter UI component.
249 | #'
250 | #' @param ns Shiny's namespace function.
251 | #' @param ... Any other argument.
252 | #'
253 | #' @keywords internal
254 | .counter_ui <- \(ns, ...) {
255 | shiny::div(
256 | shiny::h1("Counter"),
257 | shiny::tags$button(
258 | class = "btn btn-sm btn-primary",
259 | id = ns("button"),
260 | "Counter"
261 | ),
262 | shiny::p(
263 | id = ns("output"),
264 | 0L
265 | )
266 | )
267 | }
268 |
269 | #' counter server
270 | #'
271 | #' counter server component.
272 | #'
273 | #' @param input,output,session Arguments passed from mdoule's server.
274 | #' @param ... Any other argument.
275 | #'
276 | #' @keywords internal
277 | .counter_server <- \(input, output, session, ...) {}
278 | ```
279 |
280 | Then, after documenting, it can be used as.
281 |
282 | ```r
283 | library(shiny)
284 |
285 | ui <- fluidPage(
286 | title = "Test",
287 | counter_ui("c1", color = "red"),
288 | counter_ui("c2", color = "blue"),
289 | )
290 |
291 | server <- function(...){
292 | counter_server("c1")
293 | counter_server("c2")
294 | }
295 |
296 | shinyApp(ui, server)
297 | ```

2 | ==========================
3 |
4 | _Version 3, 29 June 2007_
5 | _Copyright © 2007 Free Software Foundation, Inc. <>_
6 |
7 | Everyone is permitted to copy and distribute verbatim copies of this license
8 | document, but changing it is not allowed.
9 |
10 | ## Preamble
11 |
12 | The GNU General Public License is a free, copyleft license for software and other
13 | kinds of works.
14 |
15 | The licenses for most software and other practical works are designed to take away
16 | your freedom to share and change the works. By contrast, the GNU General Public
17 | License is intended to guarantee your freedom to share and change all versions of a
18 | program--to make sure it remains free software for all its users. We, the Free
19 | Software Foundation, use the GNU General Public License for most of our software; it
20 | applies also to any other work released this way by its authors. You can apply it to
21 | your programs, too.
22 |
23 | When we speak of free software, we are referring to freedom, not price. Our General
24 | Public Licenses are designed to make sure that you have the freedom to distribute
25 | copies of free software (and charge for them if you wish), that you receive source
26 | code or can get it if you want it, that you can change the software or use pieces of
27 | it in new free programs, and that you know you can do these things.
28 |
29 | To protect your rights, we need to prevent others from denying you these rights or
30 | asking you to surrender the rights. Therefore, you have certain responsibilities if
31 | you distribute copies of the software, or if you modify it: responsibilities to
32 | respect the freedom of others.
33 |
34 | For example, if you distribute copies of such a program, whether gratis or for a fee,
35 | you must pass on to the recipients the same freedoms that you received. You must make
36 | sure that they, too, receive or can get the source code. And you must show them these
37 | terms so they know their rights.
38 |
39 | Developers that use the GNU GPL protect your rights with two steps: **(1)** assert
40 | copyright on the software, and **(2)** offer you this License giving you legal permission
41 | to copy, distribute and/or modify it.
42 |
43 | For the developers' and authors' protection, the GPL clearly explains that there is
44 | no warranty for this free software. For both users' and authors' sake, the GPL
45 | requires that modified versions be marked as changed, so that their problems will not
46 | be attributed erroneously to authors of previous versions.
47 |
48 | Some devices are designed to deny users access to install or run modified versions of
49 | the software inside them, although the manufacturer can do so. This is fundamentally
50 | incompatible with the aim of protecting users' freedom to change the software. The
51 | systematic pattern of such abuse occurs in the area of products for individuals to
52 | use, which is precisely where it is most unacceptable. Therefore, we have designed
53 | this version of the GPL to prohibit the practice for those products. If such problems
54 | arise substantially in other domains, we stand ready to extend this provision to
55 | those domains in future versions of the GPL, as needed to protect the freedom of
56 | users.
57 |
58 | Finally, every program is threatened constantly by software patents. States should
59 | not allow patents to restrict development and use of software on general-purpose
60 | computers, but in those that do, we wish to avoid the special danger that patents
61 | applied to a free program could make it effectively proprietary. To prevent this, the
62 | GPL assures that patents cannot be used to render the program non-free.
63 |
64 | The precise terms and conditions for copying, distribution and modification follow.
65 |
66 | ## TERMS AND CONDITIONS
67 |
68 | ### 0. Definitions
69 |
70 | “This License” refers to version 3 of the GNU General Public License.
71 |
72 | “Copyright” also means copyright-like laws that apply to other kinds of
73 | works, such as semiconductor masks.
74 |
75 | “The Program” refers to any copyrightable work licensed under this
76 | License. Each licensee is addressed as “you”. “Licensees” and
77 | “recipients” may be individuals or organizations.
78 |
79 | To “modify” a work means to copy from or adapt all or part of the work in
80 | a fashion requiring copyright permission, other than the making of an exact copy. The
81 | resulting work is called a “modified version” of the earlier work or a
82 | work “based on” the earlier work.
83 |
84 | A “covered work” means either the unmodified Program or a work based on
85 | the Program.
86 |
87 | To “propagate” a work means to do anything with it that, without
88 | permission, would make you directly or secondarily liable for infringement under
89 | applicable copyright law, except executing it on a computer or modifying a private
90 | copy. Propagation includes copying, distribution (with or without modification),
91 | making available to the public, and in some countries other activities as well.
92 |
93 | To “convey” a work means any kind of propagation that enables other
94 | parties to make or receive copies. Mere interaction with a user through a computer
95 | network, with no transfer of a copy, is not conveying.
96 |
97 | An interactive user interface displays “Appropriate Legal Notices” to the
98 | extent that it includes a convenient and prominently visible feature that **(1)**
99 | displays an appropriate copyright notice, and **(2)** tells the user that there is no
100 | warranty for the work (except to the extent that warranties are provided), that
101 | licensees may convey the work under this License, and how to view a copy of this
102 | License. If the interface presents a list of user commands or options, such as a
103 | menu, a prominent item in the list meets this criterion.
104 |
105 | ### 1. Source Code
106 |
107 | The “source code” for a work means the preferred form of the work for
108 | making modifications to it. “Object code” means any non-source form of a
109 | work.
110 |
111 | A “Standard Interface” means an interface that either is an official
112 | standard defined by a recognized standards body, or, in the case of interfaces
113 | specified for a particular programming language, one that is widely used among
114 | developers working in that language.
115 |
116 | The “System Libraries” of an executable work include anything, other than
117 | the work as a whole, that **(a)** is included in the normal form of packaging a Major
118 | Component, but which is not part of that Major Component, and **(b)** serves only to
119 | enable use of the work with that Major Component, or to implement a Standard
120 | Interface for which an implementation is available to the public in source code form.
121 | A “Major Component”, in this context, means a major essential component
122 | (kernel, window system, and so on) of the specific operating system (if any) on which
123 | the executable work runs, or a compiler used to produce the work, or an object code
124 | interpreter used to run it.
125 |
126 | The “Corresponding Source” for a work in object code form means all the
127 | source code needed to generate, install, and (for an executable work) run the object
128 | code and to modify the work, including scripts to control those activities. However,
129 | it does not include the work's System Libraries, or general-purpose tools or
130 | generally available free programs which are used unmodified in performing those
131 | activities but which are not part of the work. For example, Corresponding Source
132 | includes interface definition files associated with source files for the work, and
133 | the source code for shared libraries and dynamically linked subprograms that the work
134 | is specifically designed to require, such as by intimate data communication or
135 | control flow between those subprograms and other parts of the work.
136 |
137 | The Corresponding Source need not include anything that users can regenerate
138 | automatically from other parts of the Corresponding Source.
139 |
140 | The Corresponding Source for a work in source code form is that same work.
141 |
142 | ### 2. Basic Permissions
143 |
144 | All rights granted under this License are granted for the term of copyright on the
145 | Program, and are irrevocable provided the stated conditions are met. This License
146 | explicitly affirms your unlimited permission to run the unmodified Program. The
147 | output from running a covered work is covered by this License only if the output,
148 | given its content, constitutes a covered work. This License acknowledges your rights
149 | of fair use or other equivalent, as provided by copyright law.
150 |
151 | You may make, run and propagate covered works that you do not convey, without
152 | conditions so long as your license otherwise remains in force. You may convey covered
153 | works to others for the sole purpose of having them make modifications exclusively
154 | for you, or provide you with facilities for running those works, provided that you
155 | comply with the terms of this License in conveying all material for which you do not
156 | control copyright. Those thus making or running the covered works for you must do so
157 | exclusively on your behalf, under your direction and control, on terms that prohibit
158 | them from making any copies of your copyrighted material outside their relationship
159 | with you.
160 |
161 | Conveying under any other circumstances is permitted solely under the conditions
162 | stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
163 |
164 | ### 3. Protecting Users' Legal Rights From Anti-Circumvention Law
165 |
166 | No covered work shall be deemed part of an effective technological measure under any
167 | applicable law fulfilling obligations under article 11 of the WIPO copyright treaty
168 | adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention
169 | of such measures.
170 |
171 | When you convey a covered work, you waive any legal power to forbid circumvention of
172 | technological measures to the extent such circumvention is effected by exercising
173 | rights under this License with respect to the covered work, and you disclaim any
174 | intention to limit operation or modification of the work as a means of enforcing,
175 | against the work's users, your or third parties' legal rights to forbid circumvention
176 | of technological measures.
177 |
178 | ### 4. Conveying Verbatim Copies
179 |
180 | You may convey verbatim copies of the Program's source code as you receive it, in any
181 | medium, provided that you conspicuously and appropriately publish on each copy an
182 | appropriate copyright notice; keep intact all notices stating that this License and
183 | any non-permissive terms added in accord with section 7 apply to the code; keep
184 | intact all notices of the absence of any warranty; and give all recipients a copy of
185 | this License along with the Program.
186 |
187 | You may charge any price or no price for each copy that you convey, and you may offer
188 | support or warranty protection for a fee.
189 |
190 | ### 5. Conveying Modified Source Versions
191 |
192 | You may convey a work based on the Program, or the modifications to produce it from
193 | the Program, in the form of source code under the terms of section 4, provided that
194 | you also meet all of these conditions:
195 |
196 | * **a)** The work must carry prominent notices stating that you modified it, and giving a
197 | relevant date.
198 | * **b)** The work must carry prominent notices stating that it is released under this
199 | License and any conditions added under section 7. This requirement modifies the
200 | requirement in section 4 to “keep intact all notices”.
201 | * **c)** You must license the entire work, as a whole, under this License to anyone who
202 | comes into possession of a copy. This License will therefore apply, along with any
203 | applicable section 7 additional terms, to the whole of the work, and all its parts,
204 | regardless of how they are packaged. This License gives no permission to license the
205 | work in any other way, but it does not invalidate such permission if you have
206 | separately received it.
207 | * **d)** If the work has interactive user interfaces, each must display Appropriate Legal
208 | Notices; however, if the Program has interactive interfaces that do not display
209 | Appropriate Legal Notices, your work need not make them do so.
210 |
211 | A compilation of a covered work with other separate and independent works, which are
212 | not by their nature extensions of the covered work, and which are not combined with
213 | it such as to form a larger program, in or on a volume of a storage or distribution
214 | medium, is called an “aggregate” if the compilation and its resulting
215 | copyright are not used to limit the access or legal rights of the compilation's users
216 | beyond what the individual works permit. Inclusion of a covered work in an aggregate
217 | does not cause this License to apply to the other parts of the aggregate.
218 |
219 | ### 6. Conveying Non-Source Forms
220 |
221 | You may convey a covered work in object code form under the terms of sections 4 and
222 | 5, provided that you also convey the machine-readable Corresponding Source under the
223 | terms of this License, in one of these ways:
224 |
225 | * **a)** Convey the object code in, or embodied in, a physical product (including a
226 | physical distribution medium), accompanied by the Corresponding Source fixed on a
227 | durable physical medium customarily used for software interchange.
228 | * **b)** Convey the object code in, or embodied in, a physical product (including a
229 | physical distribution medium), accompanied by a written offer, valid for at least
230 | three years and valid for as long as you offer spare parts or customer support for
231 | that product model, to give anyone who possesses the object code either **(1)** a copy of
232 | the Corresponding Source for all the software in the product that is covered by this
233 | License, on a durable physical medium customarily used for software interchange, for
234 | a price no more than your reasonable cost of physically performing this conveying of
235 | source, or **(2)** access to copy the Corresponding Source from a network server at no
236 | charge.
237 | * **c)** Convey individual copies of the object code with a copy of the written offer to
238 | provide the Corresponding Source. This alternative is allowed only occasionally and
239 | noncommercially, and only if you received the object code with such an offer, in
240 | accord with subsection 6b.
241 | * **d)** Convey the object code by offering access from a designated place (gratis or for
242 | a charge), and offer equivalent access to the Corresponding Source in the same way
243 | through the same place at no further charge. You need not require recipients to copy
244 | the Corresponding Source along with the object code. If the place to copy the object
245 | code is a network server, the Corresponding Source may be on a different server
246 | (operated by you or a third party) that supports equivalent copying facilities,
247 | provided you maintain clear directions next to the object code saying where to find
248 | the Corresponding Source. Regardless of what server hosts the Corresponding Source,
249 | you remain obligated to ensure that it is available for as long as needed to satisfy
250 | these requirements.
251 | * **e)** Convey the object code using peer-to-peer transmission, provided you inform
252 | other peers where the object code and Corresponding Source of the work are being
253 | offered to the general public at no charge under subsection 6d.
254 |
255 | A separable portion of the object code, whose source code is excluded from the
256 | Corresponding Source as a System Library, need not be included in conveying the
257 | object code work.
258 |
259 | A “User Product” is either **(1)** a “consumer product”, which
260 | means any tangible personal property which is normally used for personal, family, or
261 | household purposes, or **(2)** anything designed or sold for incorporation into a
262 | dwelling. In determining whether a product is a consumer product, doubtful cases
263 | shall be resolved in favor of coverage. For a particular product received by a
264 | particular user, “normally used” refers to a typical or common use of
265 | that class of product, regardless of the status of the particular user or of the way
266 | in which the particular user actually uses, or expects or is expected to use, the
267 | product. A product is a consumer product regardless of whether the product has
268 | substantial commercial, industrial or non-consumer uses, unless such uses represent
269 | the only significant mode of use of the product.
270 |
271 | “Installation Information” for a User Product means any methods,
272 | procedures, authorization keys, or other information required to install and execute
273 | modified versions of a covered work in that User Product from a modified version of
274 | its Corresponding Source. The information must suffice to ensure that the continued
275 | functioning of the modified object code is in no case prevented or interfered with
276 | solely because modification has been made.
277 |
278 | If you convey an object code work under this section in, or with, or specifically for
279 | use in, a User Product, and the conveying occurs as part of a transaction in which
280 | the right of possession and use of the User Product is transferred to the recipient
281 | in perpetuity or for a fixed term (regardless of how the transaction is
282 | characterized), the Corresponding Source conveyed under this section must be
283 | accompanied by the Installation Information. But this requirement does not apply if
284 | neither you nor any third party retains the ability to install modified object code
285 | on the User Product (for example, the work has been installed in ROM).
286 |
287 | The requirement to provide Installation Information does not include a requirement to
288 | continue to provide support service, warranty, or updates for a work that has been
289 | modified or installed by the recipient, or for the User Product in which it has been
290 | modified or installed. Access to a network may be denied when the modification itself
291 | materially and adversely affects the operation of the network or violates the rules
292 | and protocols for communication across the network.
293 |
294 | Corresponding Source conveyed, and Installation Information provided, in accord with
295 | this section must be in a format that is publicly documented (and with an
296 | implementation available to the public in source code form), and must require no
297 | special password or key for unpacking, reading or copying.
298 |
299 | ### 7. Additional Terms
300 |
301 | “Additional permissions” are terms that supplement the terms of this
302 | License by making exceptions from one or more of its conditions. Additional
303 | permissions that are applicable to the entire Program shall be treated as though they
304 | were included in this License, to the extent that they are valid under applicable
305 | law. If additional permissions apply only to part of the Program, that part may be
306 | used separately under those permissions, but the entire Program remains governed by
307 | this License without regard to the additional permissions.
308 |
309 | When you convey a copy of a covered work, you may at your option remove any
310 | additional permissions from that copy, or from any part of it. (Additional
311 | permissions may be written to require their own removal in certain cases when you
312 | modify the work.) You may place additional permissions on material, added by you to a
313 | covered work, for which you have or can give appropriate copyright permission.
314 |
315 | Notwithstanding any other provision of this License, for material you add to a
316 | covered work, you may (if authorized by the copyright holders of that material)
317 | supplement the terms of this License with terms:
318 |
319 | * **a)** Disclaiming warranty or limiting liability differently from the terms of
320 | sections 15 and 16 of this License; or
321 | * **b)** Requiring preservation of specified reasonable legal notices or author
322 | attributions in that material or in the Appropriate Legal Notices displayed by works
323 | containing it; or
324 | * **c)** Prohibiting misrepresentation of the origin of that material, or requiring that
325 | modified versions of such material be marked in reasonable ways as different from the
326 | original version; or
327 | * **d)** Limiting the use for publicity purposes of names of licensors or authors of the
328 | material; or
329 | * **e)** Declining to grant rights under trademark law for use of some trade names,
330 | trademarks, or service marks; or
331 | * **f)** Requiring indemnification of licensors and authors of that material by anyone
332 | who conveys the material (or modified versions of it) with contractual assumptions of
333 | liability to the recipient, for any liability that these contractual assumptions
334 | directly impose on those licensors and authors.
335 |
336 | All other non-permissive additional terms are considered “further
337 | restrictions” within the meaning of section 10. If the Program as you received
338 | it, or any part of it, contains a notice stating that it is governed by this License
339 | along with a term that is a further restriction, you may remove that term. If a
340 | license document contains a further restriction but permits relicensing or conveying
341 | under this License, you may add to a covered work material governed by the terms of
342 | that license document, provided that the further restriction does not survive such
343 | relicensing or conveying.
344 |
345 | If you add terms to a covered work in accord with this section, you must place, in
346 | the relevant source files, a statement of the additional terms that apply to those
347 | files, or a notice indicating where to find the applicable terms.
348 |
349 | Additional terms, permissive or non-permissive, may be stated in the form of a
350 | separately written license, or stated as exceptions; the above requirements apply
351 | either way.
352 |
353 | ### 8. Termination
354 |
355 | You may not propagate or modify a covered work except as expressly provided under
356 | this License. Any attempt otherwise to propagate or modify it is void, and will
357 | automatically terminate your rights under this License (including any patent licenses
358 | granted under the third paragraph of section 11).
359 |
360 | However, if you cease all violation of this License, then your license from a
361 | particular copyright holder is reinstated **(a)** provisionally, unless and until the
362 | copyright holder explicitly and finally terminates your license, and **(b)** permanently,
363 | if the copyright holder fails to notify you of the violation by some reasonable means
364 | prior to 60 days after the cessation.
365 |
366 | Moreover, your license from a particular copyright holder is reinstated permanently
367 | if the copyright holder notifies you of the violation by some reasonable means, this
368 | is the first time you have received notice of violation of this License (for any
369 | work) from that copyright holder, and you cure the violation prior to 30 days after
370 | your receipt of the notice.
371 |
372 | Termination of your rights under this section does not terminate the licenses of
373 | parties who have received copies or rights from you under this License. If your
374 | rights have been terminated and not permanently reinstated, you do not qualify to
375 | receive new licenses for the same material under section 10.
376 |
377 | ### 9. Acceptance Not Required for Having Copies
378 |
379 | You are not required to accept this License in order to receive or run a copy of the
380 | Program. Ancillary propagation of a covered work occurring solely as a consequence of
381 | using peer-to-peer transmission to receive a copy likewise does not require
382 | acceptance. However, nothing other than this License grants you permission to
383 | propagate or modify any covered work. These actions infringe copyright if you do not
384 | accept this License. Therefore, by modifying or propagating a covered work, you
385 | indicate your acceptance of this License to do so.
386 |
387 | ### 10. Automatic Licensing of Downstream Recipients
388 |
389 | Each time you convey a covered work, the recipient automatically receives a license
390 | from the original licensors, to run, modify and propagate that work, subject to this
391 | License. You are not responsible for enforcing compliance by third parties with this
392 | License.
393 |
394 | An “entity transaction” is a transaction transferring control of an
395 | organization, or substantially all assets of one, or subdividing an organization, or
396 | merging organizations. If propagation of a covered work results from an entity
397 | transaction, each party to that transaction who receives a copy of the work also
398 | receives whatever licenses to the work the party's predecessor in interest had or
399 | could give under the previous paragraph, plus a right to possession of the
400 | Corresponding Source of the work from the predecessor in interest, if the predecessor
401 | has it or can get it with reasonable efforts.
402 |
403 | You may not impose any further restrictions on the exercise of the rights granted or
404 | affirmed under this License. For example, you may not impose a license fee, royalty,
405 | or other charge for exercise of rights granted under this License, and you may not
406 | initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging
407 | that any patent claim is infringed by making, using, selling, offering for sale, or
408 | importing the Program or any portion of it.
409 |
410 | ### 11. Patents
411 |
412 | A “contributor” is a copyright holder who authorizes use under this
413 | License of the Program or a work on which the Program is based. The work thus
414 | licensed is called the contributor's “contributor version”.
415 |
416 | A contributor's “essential patent claims” are all patent claims owned or
417 | controlled by the contributor, whether already acquired or hereafter acquired, that
418 | would be infringed by some manner, permitted by this License, of making, using, or
419 | selling its contributor version, but do not include claims that would be infringed
420 | only as a consequence of further modification of the contributor version. For
421 | purposes of this definition, “control” includes the right to grant patent
422 | sublicenses in a manner consistent with the requirements of this License.
423 |
424 | Each contributor grants you a non-exclusive, worldwide, royalty-free patent license
425 | under the contributor's essential patent claims, to make, use, sell, offer for sale,
426 | import and otherwise run, modify and propagate the contents of its contributor
427 | version.
428 |
429 | In the following three paragraphs, a “patent license” is any express
430 | agreement or commitment, however denominated, not to enforce a patent (such as an
431 | express permission to practice a patent or covenant not to sue for patent
432 | infringement). To “grant” such a patent license to a party means to make
433 | such an agreement or commitment not to enforce a patent against the party.
434 |
435 | If you convey a covered work, knowingly relying on a patent license, and the
436 | Corresponding Source of the work is not available for anyone to copy, free of charge
437 | and under the terms of this License, through a publicly available network server or
438 | other readily accessible means, then you must either **(1)** cause the Corresponding
439 | Source to be so available, or **(2)** arrange to deprive yourself of the benefit of the
440 | patent license for this particular work, or **(3)** arrange, in a manner consistent with
441 | the requirements of this License, to extend the patent license to downstream
442 | recipients. “Knowingly relying” means you have actual knowledge that, but
443 | for the patent license, your conveying the covered work in a country, or your
444 | recipient's use of the covered work in a country, would infringe one or more
445 | identifiable patents in that country that you have reason to believe are valid.
446 |
447 | If, pursuant to or in connection with a single transaction or arrangement, you
448 | convey, or propagate by procuring conveyance of, a covered work, and grant a patent
449 | license to some of the parties receiving the covered work authorizing them to use,
450 | propagate, modify or convey a specific copy of the covered work, then the patent
451 | license you grant is automatically extended to all recipients of the covered work and
452 | works based on it.
453 |
454 | A patent license is “discriminatory” if it does not include within the
455 | scope of its coverage, prohibits the exercise of, or is conditioned on the
456 | non-exercise of one or more of the rights that are specifically granted under this
457 | License. You may not convey a covered work if you are a party to an arrangement with
458 | a third party that is in the business of distributing software, under which you make
459 | payment to the third party based on the extent of your activity of conveying the
460 | work, and under which the third party grants, to any of the parties who would receive
461 | the covered work from you, a discriminatory patent license **(a)** in connection with
462 | copies of the covered work conveyed by you (or copies made from those copies), or **(b)**
463 | primarily for and in connection with specific products or compilations that contain
464 | the covered work, unless you entered into that arrangement, or that patent license
465 | was granted, prior to 28 March 2007.
466 |
467 | Nothing in this License shall be construed as excluding or limiting any implied
468 | license or other defenses to infringement that may otherwise be available to you
469 | under applicable patent law.
470 |
471 | ### 12. No Surrender of Others' Freedom
472 |
473 | If conditions are imposed on you (whether by court order, agreement or otherwise)
474 | that contradict the conditions of this License, they do not excuse you from the
475 | conditions of this License. If you cannot convey a covered work so as to satisfy
476 | simultaneously your obligations under this License and any other pertinent
477 | obligations, then as a consequence you may not convey it at all. For example, if you
478 | agree to terms that obligate you to collect a royalty for further conveying from
479 | those to whom you convey the Program, the only way you could satisfy both those terms
480 | and this License would be to refrain entirely from conveying the Program.
481 |
482 | ### 13. Use with the GNU Affero General Public License
483 |
484 | Notwithstanding any other provision of this License, you have permission to link or
485 | combine any covered work with a work licensed under version 3 of the GNU Affero
486 | General Public License into a single combined work, and to convey the resulting work.
487 | The terms of this License will continue to apply to the part which is the covered
488 | work, but the special requirements of the GNU Affero General Public License, section
489 | 13, concerning interaction through a network will apply to the combination as such.
490 |
491 | ### 14. Revised Versions of this License
492 |
493 | The Free Software Foundation may publish revised and/or new versions of the GNU
494 | General Public License from time to time. Such new versions will be similar in spirit
495 | to the present version, but may differ in detail to address new problems or concerns.
496 |
497 | Each version is given a distinguishing version number. If the Program specifies that
498 | a certain numbered version of the GNU General Public License “or any later
499 | version” applies to it, you have the option of following the terms and
500 | conditions either of that numbered version or of any later version published by the
501 | Free Software Foundation. If the Program does not specify a version number of the GNU
502 | General Public License, you may choose any version ever published by the Free
503 | Software Foundation.
504 |
505 | If the Program specifies that a proxy can decide which future versions of the GNU
506 | General Public License can be used, that proxy's public statement of acceptance of a
507 | version permanently authorizes you to choose that version for the Program.
508 |
509 | Later license versions may give you additional or different permissions. However, no
510 | additional obligations are imposed on any author or copyright holder as a result of
511 | your choosing to follow a later version.
512 |
513 | ### 15. Disclaimer of Warranty
514 |
515 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
516 | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
517 | PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER
518 | EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
519 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
520 | QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
521 | DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
522 |
523 | ### 16. Limitation of Liability
524 |
525 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
526 | COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS
527 | PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
528 | INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
529 | PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE
530 | OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
531 | WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
532 | POSSIBILITY OF SUCH DAMAGES.
533 |
534 | ### 17. Interpretation of Sections 15 and 16
535 |
536 | If the disclaimer of warranty and limitation of liability provided above cannot be
537 | given local legal effect according to their terms, reviewing courts shall apply local
538 | law that most closely approximates an absolute waiver of all civil liability in
539 | connection with the Program, unless a warranty or assumption of liability accompanies
540 | a copy of the Program in return for a fee.
541 |
542 | _END OF TERMS AND CONDITIONS_
543 |
544 | ## How to Apply These Terms to Your New Programs
545 |
546 | If you develop a new program, and you want it to be of the greatest possible use to
547 | the public, the best way to achieve this is to make it free software which everyone
548 | can redistribute and change under these terms.
549 |
550 | To do so, attach the following notices to the program. It is safest to attach them
551 | to the start of each source file to most effectively state the exclusion of warranty;
552 | and each file should have at least the “copyright” line and a pointer to
553 | where the full notice is found.
554 |
555 |
556 | Copyright (C)
557 |
558 | This program is free software: you can redistribute it and/or modify
559 | it under the terms of the GNU General Public License as published by
560 | the Free Software Foundation, either version 3 of the License, or
561 | (at your option) any later version.
562 |
563 | This program is distributed in the hope that it will be useful,
