# ⛩️📰 书社
-<b>An X·S·L·T‐based static site generator.</b>
+<b>A make·file for X·M·L.</b>
<dfn>⛩️📰 书社</dfn> aims to make it easy to generate websites with
X·S·L·T and G·N·U Make.
It aims to do this with zero dependencies beyond the programs already
installed on your computer.
+(On Linux machines, you may need to install `libxml2-utils` to get the
+ commandline programs from `libxml2`.)
+
+**Note:**
+⛩️📰 书社 requires functionality present in G·N·U Make 3.81 (or later)
+ and will not work in previous versions, or other implementations of
+ Make.
+Compatibility with later versions of G·N·U Make is assumed, but not
+ tested.
## Nomenclature
- `awk`
- `cat`
+- `cksum`
- `cp`
- `date`
- `echo`
- `file`
- `find`
+- `git` (optional; set `GIT=` to disable)
+- `ln`
- `mkdir` (requires support for `-p`)
- `mv`
- `od` (requires support for `-t x1`)
This variable is used to find the ⛩️📰 书社 `lib/` folder, which is
expected to be in the same location.
-- **`MAGICDIR`:**
- The location of the magic files to use (default: `$(THISDIR)/magic`).
+- **`MAGIC`:**
+ A white·space‐separated list of magic files to use (default:
+ `$(THISDIR)/magic/*`).
+
+- **`EXTRAMAGIC`:**
+ The value of this variable is appended to `MAGIC` by default, to
+ enable additional magic files without overriding the existing ones.
- **`FINDRULES`:**
Rules to use with `find` when searching for source files.
- The default ignores hidden files, those that start with a period or
- hyphen‐minus, and those which contain a pipe, buck, or colon.
+ The default ignores files that start with a period or hyphen‐minus,
+ those which end with a cloparen, and those which contain a hash,
+ buck, percent, asterisk, colon, semi, eroteme, bracket, backslash,
+ or pipe.
+
+- **`EXTRAFINDRULES`:**
+ The value of this variable is appended to `FINDRULES` by default, to
+ enable additional rules without overriding the existing ones.
- **`FINDINCLUDERULES`:**
Rules to use with `find` when searching for includes (default:
`$(FINDRULES)`).
+- **`EXTRAFINDINCLUDERULES`:**
+ The value of this variable is appended to `FINDINCLUDERULES` by
+ default, to enable additional rules without overriding the existing
+ ones.
+
- **`PARSERS`:**
A white·space‐separated list of parsers to use (default:
`$(THISDIR)/parsers/*.xslt`).
+- **`EXTRAPARSERS`:**
+ The value of this variable is appended to `PARSERS` by default, to
+ enable additional parsers without overriding the existing ones.
+
- **`TRANSFORMS`:**
A white·space‐separated list of transforms to use (default:
`$(THISDIR)/transforms/*.xslt`).
+- **`EXTRATRANSFORMS`:**
+ The value of this variable is appended to `TRANSFORMS` by default, to
+ enable additional transforms without overriding the existing ones.
+
- **`XMLTYPES`:**
A white·space‐separated list of media types to consider X·M·L
(default: `application/xml text/xml`).
+- **`GENERATOR`:**
+ The name of the generator program (default: `⛩️📰 书社`).
+
+- **`VERSION`:**
+ The current version of `GENERATOR` (default: derived from the current
+ git tag/branch/commit).
+
+- **`SRCREV`:**
+ The current version of the source files (default: derived from the
+ current git tag/branch/commit).
+
- **`VERBOSE`:**
If this variable has a value, every recipe instruction will be
printed when it runs (default: empty).
Source files whose media type does not have an associated X·S·L·T
parser are considered “assets” and will not be transformed.
-**☡ For compatibility with this program, source filenames must not
- contain Ascii whitespace, colons (`:`), pipes (`|`), bucks (`$`),
- percents (`%`) or control characters, and must not begin with a
- hyphen‐minus (`-`).**
+**☡ For compatibility with this program, source file·names must not
+ contain Ascii white·space, colons (`:`), semis (`;`), pipes (`|`),
+ bucks (`$`), percents (`%`), hashes (`#`), asterisks (`*`), brackets
+ (`[` or `]`), erotemes (`?`), backslashes (`\`), or control
+ characters, must not begin with a hyphen‐minus (`-`), and must not
+ end with a cloparen (`)`).**
The former characters have the potential to conflict with make syntax,
- and a leading hyphen‐minus is confusable for a command‐line argument.
+ a leading hyphen‐minus is confusable for a command‐line argument, and
+ a trailing cloparen [activates a bug in G·N·U Make
+ 3.81](https://stackoverflow.com/questions/17148468/capturing-filenames-including-parentheses-with-gnu-makes-wildcard-function#comment24825307_17148894).
## Parsers
⛩️📰 书社 comes with some parsers; namely :—
- **`parsers/plain.xslt`:**
- Wraps `text/plain` contents in a `<html:pre class="plain">` element.
+ Wraps `text/plain` contents in a `<html:pre>` element.
- **`parsers/record-jar.xslt`:**
- Converts `text/record-jar` contents into a
- `<html:div class="record-jar">` of `<html:dl>` elements (one for
- each record).
+ Converts `text/record-jar` contents into a `<html:div>` of
+ `<html:dl>` elements (one for each record).
- **`parsers/tsv.xslt`:**
- Converts `text/tab-separated-values` contents into an
- `<html:table class="tsv">` element.
+ Converts `text/tab-separated-values` contents into an `<html:table>`
+ element.
New ⛩️📰 书社 parsers which target plaintext formats should have an
`<xslt:template>` element with no `@name` or `@mode` and whose
<transform
xmlns="http://www.w3.org/1999/XSL/Transform"
xmlns:html="http://www.w3.org/1999/xhtml"
+ xmlns:书社="urn:fdc:ladys.computer:20231231:Shu1She4"
version="1.0"
>
+ <书社:id>example:text/plain</书社:id>
<template match="html:script[@type='text/plain']">
<html:pre><value-of select="."/></html:pre>
</template>
on the root element of the parser to override media type support
detection.
-Parsers can also target specific dialects of X·M·L, in which case they
- operate on the same basic principles as transforms (described below).
+Even when `@书社:supported-media-types` is set, it is a requirement
+ that each parser transform any `<html:script>` elements with a
+ `@type` which matches their registered types into something else.
+Otherwise the parser will be stuck in an endless loop.
+The result tree of applying the transform to the `<html:script>`
+ element will be reparsed (in case any new `<html:script>` elements
+ were added in its subtree), and a `@书社:parsed-by` attribute will be
+ added to each toplevel element in the result.
+The value of this attribute will be the value of the `<书社:id>`
+ toplevel element in the parser.
+
+It is possible for parsers to support zero plaintext types.
+This is useful when targeting specific dialects of X·M·L; parsers in
+ this sense operate on the same basic principles as transforms
+ (described below).
The major distinction between X·M·L parsers and transforms is where in
the process the transformation happens:
Parsers are applied *prior* to embedding (and can be used to generate
namespaced (by `@name` or `@mode`) whenever possible, to avoid
conflicts between parsers.
+### Attributes added during parsing
+
+⛩️📰 书社 will add a few attributes to the output of the parsing step,
+ namely :—
+
+- A `@书社:cksum` attribute on toplevel result elements, giving the
+ `cksum` checksum of the corresponding source file.
+
+- For the elements which result from parsing plaintext `<html:script>`
+ elements :—
+
+ - A `@书社:parsed-by` attribute, giving a space‐separated list of
+ parsers which parsed the node.
+ (Generally, this will be a list of one, but it is possible for the
+ result of a parse to be another plaintext node, which may be
+ parsed by a different parser.)
+
+ - A `@书社:media-type` attribute, giving the identified media type of
+ the plaintext node.
+
## Embedding
Documents can be embedded in other documents using a `<书社:link>`
- Set `@exclude-result-prefixes` on the root `xslt:transform` element
to reduce the number of declared namespaces in the final result.
-The params `$buildtime`, `$srctime`, and `$path` are available within
- transforms and are initialized to the current time, the time that the
- source file was last modified, and the path of the output file within
- $(DESTDIR).
+## Global Params
+
+The following params are made available globally in parsers and
+ transforms :—
+
+- **`BUILDTIME`:**
+ The current time.
+
+- **`CKSUM`:**
+ The checksum of the source file (⅌ `cksum`).
+
+- **`GENERATOR`:**
+ The value of the `GENERATOR` variable (if present).
+
+- **`SRCREV`:**
+ The value of the `SRCREV` variable (if present).
+
+- **`SRCTIME`:**
+ The time at which the source file was last modified.
+
+- **`VERSION`:**
+ The value of the `VERSION` variable (if present).
+
+The following params are only available in transforms :—
+
+- **`CATALOG`:**
+ The path of the catalog file (within `BUILDDIR`).
+
+- **`PATH`:**
+ The path of the output file (within `DESTDIR`).
