Bug spotted and fix from Giuseppe Bilotta <giuseppe.bilotta@gmail.com>.
Extend mdwn tests to cover MultiMarkdown, where applicable.

Unconditionally passing arbitrary numbers as flags turns out to be a
bad idea, because some of the "unused" values have historically had
side-effects internal to libdiscount. Detect whether the known flags
work by rendering short Markdown snippets the first time we htmlize,
checking whether each known flag is both necessary and sufficient.

The Discount package in Debian historically enabled fenced code blocks,
PHP Markdown Extra-style definition lists, and an expanded character
set for tag names. Since Discount 2.2.0 those are runtime settings, so
enable them. Unfortunately Text::Markdown::Discount doesn't yet expose
the necessary constants:
https://rt.cpan.org/Public/Bug/Display.html?id=124188
The IDANCHOR option was historically also enabled in Debian, but is not
enabled here because ikiwiki does not enable the TOC option, and
IDANCHOR does nothing without TOC.

This avoids misinterpreting initials ("C. S. Lewis was an author"),
the abbreviation for Monsieur ("M. Descartes was a philosopher") and
German page numbering ("S. 42") as ordered lists if they happen to
begin a line.
This only affects the default Discount implementation: Text::Markdown
and Text::MultiMarkdown do not have this feature anyway. A new
mdwn_alpha_list option can be used to restore the old interpretation.
|
| |
|
|
|
| |
A new mdwn_footnotes option can be used to disable footnotes in
MultiMarkdown and Discount.
|
| |
|
|
|
| |
We can ask libdiscount not to elide <style> blocks, which means we
don't have to work around them.
|
| |
|
|
|
|
| |
The Perl binding defaults to MKD_NOHEADER|MKD_NOPANTS anyway, but
making them explicit means we can use other flags of our choice,
and makes it easier to justify why those flags are appropriate.

As noted in the Try::Tiny man page, eval/$@ can be quite awkward in
corner cases, because $@ has the same properties and problems as C's
errno. While writing a regression test for definetemplate
in which it couldn't find an appropriate template, I received
<span class="error">Error: failed to process template
<span class="createlink">deftmpl</span> </span>
instead of the intended
<span class="error">Error: failed to process template
<span class="createlink">deftmpl</span> template deftmpl not
found</span>
which turned out to be because the "catch"-analogous block called
gettext before it used $@, and gettext can call define_gettext,
which uses eval.
This commit alters all current "catch"-like blocks that use $@, except
those that just do trivial things with $@ (string interpolation, string
concatenation) and call a function (die, error, print, etc.)

mdwn: Can use the discount markdown library, via the
Text::Markdown::Discount perl module.
This is preferred if available since it's the fastest currently supported
markdown library, speeding up markdown rendering by a factor of 40.
That is to say, when only rendering a lot of markdown, discount is 40x
faster. When building a ikiwiki site, ikiwiki's other overhead gets in the
way, but I still see significant speedups. Building the ikiwiki docwiki
dropped from 62 to 45 seconds, for example.
However, when multimarkdown is enabled, Text::Markdown::Multimarkdown is
still used.
While discount contains some nonstandard markdown extensions,
including tables and footnotes, AFAICS most of them are not
enabled by default in the perl bindings.
I consider sticking to non-extended markdown a desirable thing, since this
is probably not the last markdown engine. In particular, sundown is waiting
in the wings to get packaged and get a perl binding.
----
Reviewing all the showdown extensions, here are the ones that are enabled:
centered paragraphs:
->centered<-
image sizes: [dust mite](http://dust.mite =150x150)
<style>..</style> blocks are eaten. The perl binding does not provide
access to the gathered CSS. This is not legal html anyway, so unlikely
to cause breakage.

too many plugins.. brain exploding..
|
| |
|
|
|
| |
They were a bit confusing, since they did not actually set the default, and
example values are sufficient.
|
| | |
|
| |
|
|
|
| |
Also, avoid dying with a fatal error if multimarkdown is enabled and the
module doesh't load.

Markdown is such a splintered mess.. The current debian package provides
only Text::Markdown::Markdown, while all versions of Text::Markdown support
Text::Markdown::markdown, and old versions also support the capitalised version,
while new ones don't.
It's getting to the point where `grep /markdown/i %symbol_table` is the only
sane way to figure out what function to call..
|
| |
|
|
|
| |
no longer supports Text::Markdown::Markdown. All old versions of
Text::Markdown also support the lower-case version.

remove the enclosing paragraph and newline markdown wraps it in.
This allows removing several hacks around this markdown behavior from
other plugins that htmlize fragements of pages.

which has been reported to cause encoding problems (though I haven't
reproduced them), just catch a failure of markdown, and retry.
(The crazy perl bug magically disappears on the retry.)

for extended pagespecs. The old calling convention will still work for
back-compat for now.
* The calling convention for functions in the IkiWiki::PageSpec namespace
has changed so they are passed named parameters.
* Plugin interface version increased to 2.00 since I don't anticipate any
more interface changes before 2.0.

- Plugins should not need to load IkiWiki::Render to get commonly
used functions, so moved some functions from there to IkiWiki.
- Picked out the set of functions and variables that most plugins
use, documented them, and made IkiWiki export them by default,
like a proper perl module should.
- Use the other functions at your own risk.
- This is not quite complete, I still have to decide whether to
export some other things.
* Changed all plugins included in ikiwiki to not use "IkiWiki::" when
referring to stuff now exported by the IkiWiki module.
* Anyone with a third-party ikiwiki plugin is strongly enrouraged
to make like changes to it and avoid use of non-exported symboles from
"IkiWiki::".
* Link debian/changelog and debian/news to NEWS and CHANGELOG.
* Support hyperestradier version 1.4.2, which adds a new required phraseform
setting.

in case it was installed as one. Then fall back to trying
/usr/bin/markdown.
* Document in install page how to install markdown, since it has no
installation procedure in the upstream tarball.
