Currently a `[]byte` copy is returned. In most cases this is the safe thing to do, but we should just modify/grow the slice as needed.
This is faster and consumes less memory:
```
benchmark old ns/op new ns/op delta
BenchmarkReplaceShortcodeTokens-4 7350 4419 -39.88%
benchmark old allocs new allocs delta
BenchmarkReplaceShortcodeTokens-4 5 1 -80.00%
benchmark old bytes new bytes delta
BenchmarkReplaceShortcodeTokens-4 4816 1152 -76.08%
```
This commit is aso a small spring cleaning of duplicated code in the different `PageConvert` methods.
Fixes#1516
This commit replaces the regexp driven `replaceShortcodeTokens` with a handwritten one.
It wasnt't possible to handle the p-tags case without breaking performance.
This fix actually improves in that area:
```
benchmark old ns/op new ns/op delta
BenchmarkParsePage 142738 142667 -0.05%
BenchmarkReplaceShortcodeTokens 665590 575645 -13.51%
BenchmarkShortcodeLexer 176038 181074 +2.86%
benchmark old allocs new allocs delta
BenchmarkParsePage 87 87 +0.00%
BenchmarkReplaceShortcodeTokens 9631 9424 -2.15%
BenchmarkShortcodeLexer 274 274 +0.00%
benchmark old bytes new bytes delta
BenchmarkParsePage 141830 141830 +0.00%
BenchmarkReplaceShortcodeTokens 52275 35219 -32.63%
BenchmarkShortcodeLexer 30177 30178 +0.00%
```
Fixes#1148
Commit 358dcce supposedly added ".adoc" extension recognition
for AsciiDoc, but one place was missed.
Thanks to @sjfloat for reporting the bug!
See discussions at #470.
See #470
* Based on existing support for reStructuredText files
* Handles content files with extensions `.asciidoc` and `.ad`
* Pipes content through `asciidoctor --safe -`.
If `asciidoctor` is not installed, then `asciidoc --safe -`.
* To make sure `asciidoctor` or `asciidoc` is found, after adding
a piece of AsciiDoc content, run `hugo` with the `-v` flag
and look for this message:
INFO: 2015/01/23 Rendering with /usr/bin/asciidoctor ...
Caveats:
* The final "Last updated" timestamp is currently not stripped.
* When `hugo` is run with `-v`, you may see a lot of these messages
INFO: 2015/01/23 Rendering with /usr/bin/asciidoctor ...
if you have lots of `*.ad`, `*.adoc` or `*.asciidoc` files.
* Some versions of `asciidoc` may have trouble with its safe mode.
To test if you are affected, try this:
$ echo "Hello" | asciidoc --safe -
asciidoc: ERROR: unsafe: ifeval invalid
asciidoc: FAILED: ifeval invalid safe document
If so, I recommend that you install `asciidoctor` instead.
Feedback and patches welcome!
Ideally, we should be using https://github.com/VonC/asciidocgo,
@VonC's wonderful Go implementation of Asciidoctor. However,
there is still a bit of work needed for asciidocgo to expose
its API so that Hugo can actually use it.
Until then, hope this "experimental AsciiDoc support through external
helpers" can serve as a stopgap solution for our community. :-)
2015-01-30: Updated for the replaceShortcodeTokens() syntax change
2015-02-21: Add `.adoc` extension as suggested by @Fale

(Experimental) reStructuredText support was working in v0.12,
but was no longer handled after some refactoring in v0.13-DEV.
That experimental support is now restored.
Furthermore, check for both rst2html and rst2html.py in the PATH,
and execute whichever is found.
See #472 for more information.
