HTML-to-Latex
Basic script to convert HTML source into Latex
**[IN DEVELOPMENT]**
## Install
```bash
$ npm install html-to-latex
```
## Usage
Converting html text:
```javascript
import { convertText } from 'html-to-latex';
const html = `
Styled Text
`;
const tex = await convertText(html);
console.log(tex)
//\documentclass{article}
//
//\begin{document}
//
//Styled \textbf{Text}
//
//\end{document}
```
Converting html file:
```javascript
import { convertFile } from 'html-to-latex';
const html = 'filePath.html';
await convertFile(html);
```
### API
#### convertText(htmlText, options?)
Returns: `Promise`
Converts the input htmlText to a valid latex string.
##### htmlString
Type: `string`
##### options
Type: `object`
###### ignoreBreaks
Type: `boolean`
Default: `true`
CLI Options: `-ib` or `--ignore-breaks`
Instead of replacing `
` with //, ending the line, a simple space character is inserted instead.
###### preferDollarInlineMath
Type: `boolean`
Default: `false`
CLI Options: `-dm` or `--prefer-dollar-inline-math`
Replace `\(` and `\)` with `$`.
###### skipWrappingEquations
Type: `boolean`
Default: `false`
CLI Options: `-swe` or `--skip-wrapping-equations`
Is an equation is defined in a `p` tag without any other content besides that equation, it will automatically be wrapped in `\[` and `\]`.
###### includeDocumentWrapper
Type: `boolean`
Default: `false`
CLI Options: `-dw` or `--include-document-wrapper`
Adds a latex document wrapper around the converted text. This is required to have a valid latex file:
```latex
\documentclass{article}
\begin{document}
%...converted text
\end{document}
```
###### documentClass
Type: `string`
Default: `article`
CLI Options: `-dc` or `--document-class`
If a document wrapper is added, the document class will be set.
```latex
\documentclass{article}
%...
```
###### includePackages
Type: `string[]`
Default: `[]`*
CLI Options: `-ip` or `--include-packages`
If the document wrapper is added, a list of used packages will be set.
```latex
\documentclass{article}
\usepackage{packagename}
\begin{document}
%...converted text
\end{document}
```
\*If nothing is specified, the list of includes packages will be inferred from the html:
| Tag | Added Package |
|--------|---------------|
| \cfrac | amsmath |
| \img | graphicx |
| \therefore | amssymb |
###### title
Type: `string`
Default: `undefined`
CLI Options: `-t` or `--title`
If a document wrapper is added, the title will be set.
```latex
\documentclass{article}
\title{Altered Carbon}
\begin{document}
%...converted text
\end{document}
```
###### author
Type: `string`
Default: `undefined`
CLI Options: `-a` or `--author`
If a document wrapper is added, the author will be set.
```latex
\documentclass{article}
\author{Takashi Kovacs}
\begin{document}
%...converted text
\end{document}
```
###### includeDate
Type: `boolean`
Default: `false`
CLI Options: `-d` or `--incude-date`
If a document wrapper is added, the current date will be set.
```latex
\documentclass{article}
\date{\today}
\begin{document}
%...converted text
\end{document}
```
###### compilationDir
Type: `string`
Default: `process.cwd`
CLI Options: `-cdr` or `--compilation-dir`
If any images need to be downloaded for the latex compilation, they will be places in a 'images' subdirectory inside this directory.
###### autoGenImageNames
Type: `boolean`
Default: `true`
CLI Options: `-ain` or `--autogen-image-names`
To avoid any weird file names, image files that are downloaded are automatically given a random Id with the extension of the original file. This can be turned off by passing a `false` value.
###### imageWidth
Type: `string`
Default: `undefined`
CLI Options: `-iw` or `--image-width`
Allows you to set a image width. This would be in the form normally accepted by latex such as: `2cm`
###### imageHeight
Type: `string`
Default: `undefined`
CLI Options: `-ih` or `--image-height`
Allows you to set a image height. This would be in the form normally accepted by latex such as: `2cm`
###### keepImageAspectRatio
Type: `boolean`
Default: `undefined`
CLI Options: `-kar` or `--keep-aspect-ratio`
Allows you to maintain the aspect ratio of the image. This also requires either the image width property or image height property to be set.
###### debug
Type: `boolean`
Default: `false`
CLI Options: `--debug`
Prints error messages when they occur such as when an image cannot be found at the given url.
#### convertFile(filepath, options?)
CLI: `available` (see options for cli option names)
Returns: `Promise`
Converts the input file to a valid latex file.
##### filepath
Type: `string`
CLI Option: Positional, or `-ifp`
Path of html file
##### options
Type: `object`
All options included in .... and
*includeDocumentWrapper option is defaulted to true for this function, as it would make more sense to do so*
##### outputFilepath
Type: `string`
Default: `filepath` (The input file path)
CLI Option: `-ofp` or `--output-file-path`
The output filepath of the converted file. By default it will overwrite the input file.
### CLI API
The same arguments are valid for the cli. The cli is exposed under html-to-latex executable and has the functions: `convert-file` and `convert-text`. Run `html-to-latex --help` for more information.
## Improving output
### Ignoring br tags
Instead designate new sections/paragraphs using the proper html tag such as a `
