Certain environments in LaTeX will trigger math mode and can't
occur within math mode: e.g., `align` or `equation`. Previously
we "downshifted" these, parsing an `align` environment as a
Math element with `aligned`, and an `equation` environment as a
regular display math element. With this shift, we put these in
Math inlines but retain the original environments.
This works because:
1) texmath handles these environments just fine,
2) and so does MathJax;
3) when writing LaTeX we detect these environments in Math elements
and emit them verbatim instead of putting them in `$..$` or
`$$..$$`.
Closes#9711. Closes#9296.
When converting e.g. an align environment to an aligned environment
inside a Math element, we need to include a newline before the
`\end{aligned}`, since the previous line might end in a comment.
Closes#8122.
- Fixed semantics for `\let`.
- Implement `\edef`, `\gdef`, and `\xdef`.
- Add comment noting that currently `\def` and `\edef` set global
macros (so are equivalent to `\gdef` and `\xdef`). This should be
fixed by scoping macro definitions to groups, in a future commit.
Closes#7474.
The `raw_attribute` will be used to mark raw bits, even HTML
and LaTeX, and even when `raw_html` and `raw_tex` are enabled,
as they are by default.
To get the old behavior, disable `raw_attribute` in the writer.
Closes#4311.
Add support for `\|`, `\b`, `\G`, `\h`, `\d`, `\f`,
`\r`, `\t`, `\U`, `\i`, `\j`, `\newtie`, `\textcircled`.
Also fall back to combining characters when composed
characters are not available.
Closes#4652.
even if the `latex_macros` extension is set.
This reverts to earlier behavior and is probably safer
on the whole, since some macros only modify things in
included packages, which pandoc's macro expansion can't
modify.
Closes#4246.
Don't pass through macro definitions themselves when `latex_macros`
is set. The macros have already been applied.
If `latex_macros` is enabled, then `rawLaTeXBlock` in
Text.Pandoc.Readers.LaTeX will succeed in parsing a macro definition,
and will update pandoc's internal macro map accordingly, but the
empty string will be returned.
Together with earlier changes, this closes#4179.
Also, fix regular macros so they're expanded at the
point of use, and NOT also the point of definition.
`\let` macros, by contrast, are expanded at the
point of definition. Added an `ExpansionPoint`
field to `Macro` to track this difference.
Fixed applyMacros so that it operates on the whole
string, not just the first token!
Don't remove macro definitions from the output,
even if Ext_latex_macros is set, so that macros will
be applied. Since they're only applied to math in
Markdown, removing the macros can have bad effects.
Even for math macros, keeping them should be harmless.
