3 <b>A make·file for X·M·L.</b>
5 <dfn>⛩️📰 书社</dfn> aims to make it easy to generate websites with
6 X·S·L·T and G·N·U Make.
7 It is consequently only a good choice for people who like X·S·L·T and
8 G·N·U Make and wish it were easier to make websites with them.
10 It makes things easier by :—
12 - Automatically identifying source files and characterizing them by
13 type (X·M·L, text, or asset).
15 - Parsing supported text types into X·M·L trees.
17 - Enabling easy inclusion of source files within each other.
19 It aims to do this with zero dependencies beyond the programs already
20 installed on your computer.
21 (On Linux machines, you may need to install `libxml2-utils` to get the
22 commandline programs from `libxml2`.)
25 ⛩️📰 书社 requires functionality present in G·N·U Make 3.81 (or later)
26 and will not work in previous versions, or other implementations of
28 Compatibility with later versions of G·N·U Make is assumed, but not
33 <i lang="cmn-Hans">书社</i> is a Chinese word meaning “publishing
36 The first character, <i lang="cmn-Hans">书</i>, is the simplified form
39 The second character, <i lang="cmn-Hans">社</i>, contemporarily means
40 “association”, but historically referred to the god of the soil and
41 related altars or festivities.
42 In Japanese, it is an alternate spelling for <i lang="ja">やしろ</i>,
43 the word for “Shinto shrine”.
45 The name <i lang="cmn-Hans">书社</i> was chosen to play on this pun, as
46 it is intended as a publishing program for webshrines.
48 In Ascii environments, ⛩️📰 书社 should be written `Shushe`, following
49 the pinyin transliteration.
53 Place source files in `sources/` and run `make install` to compile
54 the result to `public/`.
55 Compilation involves the following steps :—
57 1. ⛩️📰 书社 compiles all of the magic files in `magic/` into a single
58 file, `build/magic.mgc`.
60 2. ⛩️📰 书社 processes all of the parsers in `parsers/` and determines
61 the list of supported plaintext types.
63 3. ⛩️📰 书社 identifies all of the source files and includes and uses
64 `build/magic.mgc` to classify them by media type.
66 4. ⛩️📰 书社 parses all plaintext and X·M·L source files and includes
67 and then builds a dependency tree between them.
69 5. ⛩️📰 书社 uses the dependency tree to establish prerequisites for
72 6. ⛩️📰 书社 compiles each output file to `build/public`.
74 7. ⛩️📰 书社 copies the output files to `public`.
76 You can use `make list` to list each identified source file or include
77 alongside its computed type and dependencies.
78 As this is a Make‐based program, steps will only be run if the
79 corresponding buildfile or output file is older than its
84 The ⛩️📰 书社 namespace is `urn:fdc:ladys.computer:20231231:Shu1She4`.
86 This document uses a few namespace prefixes, with the following
89 | Prefix | Expansion |
90 | -------: | :----------------------------------------- |
91 | `html:` | `http://www.w3.org/1999/xhtml` |
92 | `xlink:` | `http://www.w3.org/1999/xlink` |
93 | `xslt:` | `http://www.w3.org/1999/XSL/Transform` |
94 | `书社:` | `urn:fdc:ladys.computer:20231231:Shu1She4` |
96 ## Setup and Configuration
98 ⛩️📰 书社 depends on the following programs to run.
99 In every case, you may supply your own implementation by overriding the
100 corresponding (allcaps) variable (e·g, set `MKDIR` to supply your own
101 `mkdir` implementation).
110 - `git` (optional; set `GIT=` to disable)
112 - `mkdir` (requires support for `-p`)
114 - `od` (requires support for `-t x1`)
122 - `tr` (requires support for `-d`)
123 - `uuencode` (requires support for `-m` and `-r`)
124 - `xargs` (requires support for `-0`)
125 - `xmlcatalog` (provided by `libxml2`)
126 - `xmllint` (provided by `libxml2`)
127 - `xsltproc` (provided by `libxslt`)
129 The following additional variables can be used to control the behaviour
133 The location of the source files (default: `sources`).
134 Multiple source directories can be provided, so long as the same
135 file subpath doesn’t exist in more than one of them.
138 The location of source includes (default: `sources/includes`).
139 This can be inside of `SRCDIR`, but needn’t be.
140 Multiple include directories can be provided, so long as the same
141 file subpath doesn’t exist in more than one of them.
144 The location of the (temporary) build directory (default: `build`).
145 `make clean` will delete this, and it is recommended that it not be
146 used for programs aside from ⛩️📰 书社.
149 The location of directory to output files to (default: `public`).
150 `make install` will overwrite files in this directory which
151 correspond to those in `SRCDIR`.
152 It *will not* touch other files, including those generated from files
153 in `SRCDIR` which have since been deleted.
155 Files are first compiled to `$(BUILDDIR)/public` before they are
156 copied to `DESTDIR`, so this folder is relatively quick and
157 inexpensive to re·create.
158 It’s reasonable to simply delete it before every `make install` to
159 ensure stale content is removed.
162 The location of the ⛩️📰 书社 `GNUmakefile`.
163 This should be set automatically when calling Make and shouldn’t ever
164 need to be set manually.
165 This variable is used to find the ⛩️📰 书社 `lib/` folder, which is
166 expected to be in the same location.
169 A white·space‐separated list of magic files to use (default:
170 `$(THISDIR)/magic/*`).
173 The value of this variable is appended to `MAGIC` by default, to
174 enable additional magic files without overriding the existing ones.
177 Rules to use with `find` when searching for source files.
178 The default ignores files that start with a period or hyphen‐minus,
179 those which end with a cloparen, and those which contain a hash,
180 buck, percent, asterisk, colon, semi, eroteme, bracket, backslash,
183 - **`EXTRAFINDRULES`:**
184 The value of this variable is appended to `FINDRULES` by default, to
185 enable additional rules without overriding the existing ones.
187 - **`FINDINCLUDERULES`:**
188 Rules to use with `find` when searching for includes (default:
191 - **`EXTRAFINDINCLUDERULES`:**
192 The value of this variable is appended to `FINDINCLUDERULES` by
193 default, to enable additional rules without overriding the existing
197 A white·space‐separated list of parsers to use (default:
198 `$(THISDIR)/parsers/*.xslt`).
200 - **`EXTRAPARSERS`:**
201 The value of this variable is appended to `PARSERS` by default, to
202 enable additional parsers without overriding the existing ones.
205 A white·space‐separated list of transforms to use (default:
206 `$(THISDIR)/transforms/*.xslt`).
208 - **`EXTRATRANSFORMS`:**
209 The value of this variable is appended to `TRANSFORMS` by default, to
210 enable additional transforms without overriding the existing ones.
213 A white·space‐separated list of media types to consider X·M·L
214 (default: `application/xml text/xml`).
217 The name of the generator program (default: `⛩️📰 书社`).
220 The current version of `GENERATOR` (default: derived from the current
221 git tag/branch/commit).
224 The current version of the source files (default: derived from the
225 current git tag/branch/commit).
228 If this variable has a value, every recipe instruction will be
229 printed when it runs (default: empty).
230 This is helpful for debugging, but typically too noisy for general
235 Source files may be placed in `SRCDIR` in any manner; the file
236 structure used there will match the output.
237 The type of source files is *not* determined by file extension, but
238 rather by magic number; this means that files **must** begin with
239 something recognizable.
240 Supported magic numbers include :—
242 - `<?xml` for `application/xml` files
243 - `#!js` for `text/javascript` files
244 - `@charset "` for `text/css` files
245 - `#!tsv` for `text/tab-separated-values` files
246 - `%%` for `text/record-jar` files (unregistered; see
247 [[draft-phillips-record-jar-01][]])
249 Text formats with associated X·S·L·T parsers are wrapped in a H·T·M·L
250 `<script>` element whose `@type` gives its media type, and then
251 passed to the parser to process.
252 Source files whose media type does not have an associated X·S·L·T
253 parser are considered “assets” and will not be transformed.
255 **☡ For compatibility with this program, source file·names must not
256 contain Ascii white·space, colons (`:`), semis (`;`), pipes (`|`),
257 bucks (`$`), percents (`%`), hashes (`#`), asterisks (`*`), brackets
258 (`[` or `]`), erotemes (`?`), backslashes (`\`), or control
259 characters, must not begin with a hyphen‐minus (`-`), and must not
260 end with a cloparen (`)`).**
261 The former characters have the potential to conflict with make syntax,
262 a leading hyphen‐minus is confusable for a command‐line argument, and
263 a trailing cloparen [activates a bug in G·N·U Make
264 3.81](https://stackoverflow.com/questions/17148468/capturing-filenames-including-parentheses-with-gnu-makes-wildcard-function#comment24825307_17148894).
268 Parsers are used to convert plaintext files into X·M·L trees, as well
269 as convert plaintext formats which are already included inline in
270 existing source X·M·L documents.
271 ⛩️📰 书社 comes with some parsers; namely :—
273 - **`parsers/plain.xslt`:**
274 Wraps `text/plain` contents in a `<html:pre class="plain">` element.
276 - **`parsers/record-jar.xslt`:**
277 Converts `text/record-jar` contents into a
278 `<html:div class="record-jar">` of `<html:dl>` elements (one for
281 - **`parsers/tsv.xslt`:**
282 Converts `text/tab-separated-values` contents into an
283 `<html:table class="tsv">` element.
285 New ⛩️📰 书社 parsers which target plaintext formats should have an
286 `<xslt:template>` element with no `@name` or `@mode` and whose
289 - Starts with an appropriately‐namespaced qualified name for a
290 `<html:script>` element.
292 - Follows this with the string `[@type=`.
294 - Follows this with a quoted string giving a media type supported by
296 Media type parameters are *not* supported.
298 - Follows this with the string `]`.
300 For example, the trivial `text/plain` parser is defined as follows :—
303 <?xml version="1.0"?>
305 xmlns="http://www.w3.org/1999/XSL/Transform"
306 xmlns:html="http://www.w3.org/1999/xhtml"
307 xmlns:书社="urn:fdc:ladys.computer:20231231:Shu1She4"
310 <书社:id>example:text/plain</书社:id>
311 <template match="html:script[@type='text/plain']">
312 <html:pre><value-of select="."/></html:pre>
317 ⛩️📰 书社 will scan the provided parsers for this pattern to determine
318 the set of allowed plaintext file types.
319 Multiple such `<xslt:template>` elements may be provided in a single
320 parser, for example if the parser supports multiple media types.
321 Alternatively, you can set the `@书社:supported-media-types` attribute
322 on the root element of the parser to override media type support
325 Even when `@书社:supported-media-types` is set, it is a requirement
326 that each parser transform any `<html:script>` elements with a
327 `@type` which matches their registered types into something else.
328 Otherwise the parser will be stuck in an endless loop.
329 The result tree of applying the transform to the `<html:script>`
330 element will be reparsed (in case any new `<html:script>` elements
331 were added in its subtree), and a `@书社:parsed-by` attribute will be
332 added to each toplevel element in the result.
333 The value of this attribute will be the value of the `<书社:id>`
334 toplevel element in the parser.
336 It is possible for parsers to support zero plaintext types.
337 This is useful when targeting specific dialects of X·M·L; parsers in
338 this sense operate on the same basic principles as transforms
340 The major distinction between X·M·L parsers and transforms is where in
341 the process the transformation happens:
342 Parsers are applied *prior* to embedding (and can be used to generate
343 embeds); transforms are applied *after*.
345 It is **strongly recommended** that auxillary templates in parsers be
346 namespaced (by `@name` or `@mode`) whenever possible, to avoid
347 conflicts between parsers.
351 Documents can be embedded in other documents using a `<书社:link>`
352 element with `@xlink:show="embed"`.
353 The `@xlink:href`s of these elements should have the format
354 `about:shushe?source=<path>`, where `<path>` provides the path to the
355 file within `SRCDIR`.
356 Includes, which do not generate outputs of their own but may still be
357 freely embedded, instead use the format
358 `about:shushe?include=<path>`, where `<path>` provides the path
361 Embeds are replaced with the parsed contents of a file, unless the file
362 is an asset, in which case an `<html:object>` element is produced
363 instead (with the contents of the asset file provided as a base64
366 Embedding takes place after parsing but before transformation, so
367 parsers are able to generate their own embeds.
368 ⛩️📰 书社 is able to detect the transitive embed dependencies of files
369 and update them accordingly; it will signal an error if the
370 dependencies are recursive.
372 ## Output Redirection
374 By default, ⛩️📰 书社 installs files to the same location in `DESTDIR`
375 as they were placed in their `SRCDIR`.
376 This behaviour can be customized by setting the `@书社:destination`
377 attribute on the root element, whose value can give a different path.
378 This attribute is read after parsing, but before transformation (where
379 it is silently dropped).
383 Transforms are used to convert X·M·L files into their final output,
384 after all necessary parsing and embedding has taken place.
385 ⛩️📰 书社 comes with some transforms; namely :—
387 - **`transforms/attributes.xslt`:**
388 Applies transforms to the children of any `<书社:apply-attributes>`
389 elements, and then applies the attributes of the
390 `<书社:apply-attributes>` to each result child, replacing the
391 element with the result.
392 This is useful in combination with image embeds to apply alt‐text to
393 the resulting `<html:img>`.
395 - **`transforms/asset.xslt`:**
396 Converts `<html:object>` elements which correspond to recognized
397 media types into the appropriate H·T·M·L elements, and deletes
398 `<html:style>` elements from the body of the document and moves
401 - **`transforms/metadata.xslt`:**
402 Provides basic `<html:head>` metadata.
403 This metadata is generated from `<html:meta>` elements with one of
404 the following `@itemprop` attributes :—
406 - **`urn:fdc:ladys.computer:20231231:Shu1She4:title`:**
407 Provides the title of the page.
409 ⛩️📰 书社 automatically encapsulates embeds so that their metadata
410 does not propogate up to the embedding document.
411 To undo this behaviour, remove the `@itemscope` and `@itemtype`
412 attributes from the embed during the transformation phase.
414 The following are recommendations on effective creation of
417 - Make template matchers as specific as possible.
418 It is likely an error if two transforms have templates which match
419 the same element (unless the templates have different priority).
421 - Namespace templates (with `@name` or `@mode`) whenever possible.
423 - Set `@exclude-result-prefixes` on the root `xslt:transform` element
424 to reduce the number of declared namespaces in the final result.
428 The following params are made available globally in parsers and
435 The value of the `GENERATOR` variable (if present).
438 The value of the `SRCREV` variable (if present).
441 The time at which the source file was last modified.
444 The value of the `VERSION` variable (if present).
446 The following params are only available in transforms :—
449 The path of the catalog file (within `BUILDDIR`).
452 The path of the output file (within `DESTDIR`).
456 ⛩️📰 书社 will wrap the final output of the transforms in appropriate
457 `<html:html>` and `<html:body>` elements, so it is not necessary for
458 transforms to do this explicitly.
459 After performing the initial transform, ⛩️📰 书社 will match the root
460 node of the result in the following modes to fill in areas of the
464 The result of matching in this mode is prepended into the
465 `<html:body>` of the output (before the transformation result).
468 The result of matching in this mode is appended into the
469 `<html:body>` of the output (after the transformation result).
472 The result of matching in this mode is inserted into the
473 `<html:head>` of the output.
475 In addition to being called with the transform result, each of these
476 modes will additionally be called with a `<xslt:include>` element
477 corresponding to each transform.
478 If a transform has a `<书社:id>` top‐level element whose value is an
479 i·r·i, its `<xslt:include>` element will have a corresponding
481 This mechanism can be used to allow transforms to insert content
482 without matching any elements in the result; for example, the
483 following transform adds a link to a stylesheet to the `<html:head>`
487 <?xml version="1.0"?>
