## Usage
|
|
|
|
Once this plugin is [installed](../README.md#installation), just replace
|
|
the plugin name `simple` with `semiliterate` in your `mkdocs.yml` file.
|
|
It accepts all of the same parameters, so `mkdocs` will still work as before,
|
|
and you will have immediate access to all of the following extensions.
|
|
(Note that this documentation assumes a familiarity with the
|
|
[usage](https://althack.dev/mkdocs-simple-plugin/v{! ../setup.cfg {
|
|
extract: {start: 'mkdocs~=', stop: '(\d*\.\d*\.?\d*)'},
|
|
ensurelines: false
|
|
} !}/mkdocs_simple_plugin/plugin/)
|
|
of the `simple` plugin.)

### Inclusion syntax
|
|
|
|
While extracting content from a file (because it matches one of the
|
|
`semiliterate` patterns, rather than just one of the `include_extensions`),
|
|
an unescaped expression of the form
|
|
|
|
`{! FILENAME YAML !}`
|
|
|
|
(which may span multiple lines) will trigger file inclusion. The FILENAME may
|
|
be a bare word, in which case it cannot contain whitespace, or it may be
|
|
enclosed in single or double quotes. Note that FILENAME is interpreted relative
|
|
to the directory in which the file containing the `{! .. !}` expression
|
|
resides. The YAML is interpreted exactly as the extraction options to a
|
|
`semiliterate` item as
|
|
[documented](https://althack.dev/mkdocs-simple-plugin/v{! ../setup.cfg { extract: {start: 'mkdocs~=', stop: '(\d*\.\d*\.?\d*)'}, ensurelines: false} !}/mkdocs_simple_plugin/plugin/index.html#semiliterate)
|
|
for the `simple` extension, subject to the extensions below. The text
|
|
extracted from FILENAME is interpolated at the current location in the file
|
|
currently being written. Recursive inclusion is supported.
|
|
|
|
The simplest example of such an inclusion directive is just
|
|
`{! boilerplate.md !}`, which (because of the conventions for extraction
|
|
parameters) simply interpolates the entire contents of `boilerplate.md`
|
|
at the current location.
|
|
|
|
For an example that uses more of the extraction parameters, the current
|
|
version number of mkdocs-semiliterate is extracted into the
|
|
[Overview](../README.md) of this documentation via
|
|
|
|
` {! ../README.md extract: { start: 'repo:.*(\{!.*!\})', stop: 'repo' } !}`
|
|
|
|
to take advantage of the beginning of the `setup.cfg` file:
|
|
```
|
|
{! ../setup.cfg terminate: long !}...
|
|
```
|
|
|
|
(and of course both of the code snippets just above are extracted into this
|
|
page with `{! ... !}`, as you can see in the
|
|
[source code](https://code.studioinfinity.org/glen/mkdocs-semiliterate/src/branch/main/mkdocs_semiliterate/plugin.py)
|
|
for the plugin.)
|
|
|
|
Note that a `{! ... !}` directive must be in a line that semiliterate would
|
|
normally copy. That is, semiliterate does not examine lines after
|
|
the `terminate` regexp, or when no mode of extraction is active.
|
|
It also doesn't check any text written from lines that match these
|
|
special expressions, including `start` and `stop`.
|
|
Moreover, on such normally-transcribed lines,
|
|
it's the text **after** the application of any semiliterate `replace`ments that
|
|
is checked for `{! ... !}`.

### Double-quoted filenames and special extraction
|
|
|
|
Standard Python escape sequences in double-quoted filenames are interpreted
|
|
as usual; for example you can write
|
|
```
|
|
{! ../tests/fixtures/quoted-filename/README.md extract:
|
|
start: '(.*!.*)'
|
|
stop: '\s'
|
|
!}
|
|
```
|
|
to include a file whose name (`snippet/Say "Don't"`, in this case) has both
|
|
double and single quotes.
|
|
|
|
Further, `semiliterate` supports some special escape sequences for
|
|
doublequoted file names to include text from other places than current files
|
|
in the project tree:
|
|
|
|
`\git`: extracts a version of a file from the Git archive of the project
|
|
(presuming it is under Git version control) and then
|
|
includes content from that file. For example, you could write
|
|
```
|
|
{! ../tests/fixtures/git-inclusion/README.md extract:
|
|
start: '(.*!.*)'
|
|
stop: '\s'
|
|
!}
|
|
```
|
|
|
|
to extract content starting after the `### install` line from the
|
|
`mkdocs.yml` file in the Git commit of this repository
|
|
tagged `0.1.0`. This feature is primarily useful if you are documenting the
|
|
development or changes to a project over time, or are documenting a feature
|
|
in a specific past release of your project, and want to be sure that
|
|
material included in your documentation does _not_ change as the project
|
|
progresses. (This behavior is as opposed to the usual case, in which you want
|
|
your documentation to incorporate the most up-to-date version of extracted
|
|
content.)
|
|
|
|
The precise behavior for a FILENAME argument in a `{! ... !}` inclusion of the
|
|
form
|
|
|
|
`"\git SPECIFIER"`
|
|
|
|
is that the output of `git show SPECIFIER` is written to a temporary file,
|
|
and that file is extracted from.
|
|
|
|
`\syspath`: searches for the remainder of the doublequoted filename in the
|
|
python `sys.path` and includes content from the found file. For example, you
|
|
could write
|
|
```
|
|
{! ../tests/fixtures/theme-modification/doc_theme/.base.generator extract:
|
|
start: '(.*!.*)'
|
|
!}
|
|
```
|
|
to create a version of the "base.html" of the "readthedocs" theme with
|
|
additional content at the very top of the body. As the example suggests, this
|
|
mechanism is primarily useful to tweak an mkdocs theme in ways not
|
|
anticipated by the `{%- block ... %}` directives placed by the theme writer.

: (true) Guarantees that a newline is trancribed for each line of the input,

even if a start, stop, terminate, or replacement pattern would have

suppressed the newline. Note this can be set separately for each block
|
|
(i.e. filename pattern) within the semiliterate parameter. The default

setting corresponds to the `simple` behavior, so setting this to "false"
|

allows you to suppress newlines with judicious use of these patterns.
