### LaTeX: Custom Font Configuration for Microtype

Source: https://context7.com/schlcht/microtype/llms.txt

Provides an example of a microtype configuration file (mt-myfont.cfg) for a custom font. It includes settings for character inheritance, protrusion, and expansion.

```latex
% File: mt-myfont.cfg
% Configuration for MyCustomFont family

\ProvidesFile{mt-myfont.cfg}[2024/01/01 v1.0 microtype config for MyCustomFont]

% Character inheritance
\DeclareCharacterInheritance
   { encoding = TU,
     family   = MyCustomFont }
   {
     A = {\`A, \'A},
     O = {\`O, \'O},
   }

% Protrusion settings
\SetProtrusion
   { encoding = TU,
     family   = MyCustomFont }
   {
     A  = {50,50},
     T  = {70,70},
     V  = {50,50},
     W  = {50,50},
     .  = { ,70},
     ,  = { ,70},
   }

% Expansion settings (if using selected expansion)
\SetExpansion
   { encoding = TU,
     family   = MyCustomFont }
   {
     A = 500, O = 500,
     I = 1000, L = 1000,
   }

% In your document, the file loads automatically when using the font:
% \usepackage{microtype}
% \usepackage{fontspec}
% \setmainfont{MyCustomFont}
```

--------------------------------

### Configure Font Expansion with \SetExpansion

Source: https://context7.com/schlcht/microtype/llms.txt

Define expansion settings for fonts to control glyph stretching/shrinking. Basic settings allow a maximum expansion percentage for characters. Selected expansion allows different amounts per character, with specific considerations for round or thin characters.

```latex
\documentclass{article}
\usepackage{microtype}

% Basic expansion settings
\SetExpansion
   { encoding = T1,
     family   = cmr }
   {
     A = 500,                  % allow 500/1000 = 50% of max expansion
     I = 1000,                 % allow full expansion
     O = 500,                  % round characters more sensitive
     W = 600,
   }

% Selected expansion (different amounts per character)
\usepackage[expansion,selected]{microtype}

\SetExpansion
   [ name = selected-cmr ]
   { encoding = T1,
     family   = cmr }
   {
     A = 500, B = 700, C = 800,
     I = 1000, L = 1000,       % thin chars can expand more
     M = 500, O = 400,         % round chars expand less
     W = 600,
   }

\begin{document}
Text with custom expansion settings.
\end{document}
```

### LaTeX: Using the letterspace Package

Source: https://context7.com/schlcht/microtype/llms.txt

Illustrates the usage of the standalone letterspace package for lightweight letter spacing. It provides commands similar to microtype's \textls. Do not use with microtype.

```latex
% Works with plain TeX, eplain, or LaTeX
\documentclass{article}
\usepackage{letterspace}  % Don't use with microtype!

% Or with eplain:
% \begin{packages}
% \usepackage{letterspace}
% \end{packages}

% Or with miniltx (plain TeX):
% \input miniltx
% \input letterspace.sty

\begin{document}
% Same commands as microtype
\textls{Letterspaced text}
\textls[150]{Custom amount}
\textls*{No outer kerning}
{\lsstyle Letterspaced block}

% Protect ligatures
\textls{e\lslig{ff}ects}
\end{document}
```

--------------------------------

### Configure Letterspacing with \SetTracking

Source: https://context7.com/schlcht/microtype/llms.txt

Set up systematic tracking (letterspacing) for font sets. Basic tracking applies a default spacing to small capitals. Advanced options include controlling ligatures, inner and outer spacing, and outer kerning. Different tracking can be applied based on font size.

```latex
\documentclass{article}
\usepackage[tracking=true]{microtype}

% Basic tracking for small capitals
\SetTracking
   { encoding = *,
     shape    = sc }
   { 50 }                      % 50/1000 em = 0.05em spacing

% Tracking with advanced options
\SetTracking
   [ no ligatures = {f},       % break f-ligatures (ff, fi, fl, etc.)
     spacing      = {600*,-100*,},  % inner space: 60% more, 10% less stretch
     outer spacing = {450,250,150}, % space before/after letterspaced text
     outer kerning = {*,*} ]   % default outer kern (half letterspace amount)
   { encoding = T1,
     family   = cmr }
   { 120 }                     % 120/1000 em tracking

% Different tracking for different sizes
\SetTracking{ encoding = *, size = -small }{ 20 }   % small text: slight expansion
\SetTracking{ encoding = *, size = Large- }{ -20 }  % large text: slight compression

% Track all fonts (not recommended, but possible)
\DeclareMicrotypeSet*[tracking]{all}{ encoding = * }
\SetTracking{ encoding = * }{ 30 }

\begin{document}
\textsc{Small Caps Are Tracked}

Normal text is also tracked if configured.
\end{document}
```

Source: https://context7.com/schlcht/microtype/llms.txt

Define protrusion amounts for individual characters in specific fonts. Basic settings specify protrusion for characters like 'A', 'V', 'W', and punctuation. Advanced options allow naming, inheriting, and scaling settings. Context-sensitive protrusion can be applied to specific document elements like footnotes.

```latex
\documentclass{article}
\usepackage{microtype}

% Basic protrusion settings for a font family
\SetProtrusion
   { encoding = T1,
     family   = ppl }          % Palatino
   {
     A = {50,50},              % protrude 50/1000 of char width on each side
     V = {50,50},
     W = {50,50},
     . = { ,70},               % protrude right side only
     , = { ,70},
     : = { ,50},
     ; = { ,30},
     ! = { ,100},
     ? = { ,100},
     - = {,50},                % hyphen

     {--} = {,20}              % em-dash
   }

% With options
\SetProtrusion
   [ name     = my-palatino,   % name for later reference
     load     = ppl-default,   % inherit from existing settings
     factor   = 900 ]          % scale all values to 90%
   { encoding = T1,
     family   = ppl }
   { T = {70, } }              % override T protrusion

% Context-sensitive protrusion
\SetProtrusion
   [ context = footnote ]
   { font = */*/*/*/scriptsize }

### LaTeX: Manual Protrusion with \leftprotrusion and \rightprotrusion

Source: https://context7.com/schlcht/microtype/llms.txt

Shows how to manually add protrusion at inner margins for elements like table cells or quoted text using \leftprotrusion and \rightprotrusion. Includes \noprotrusion and \noprotrusionifhmode for disabling protrusion.

```latex
\documentclass{article}
\usepackage{microtype}
\usepackage{array}

\begin{document}
% In table cells
\begin{tabular}{l>{\leftprotrusion}p{8cm}r}
Left & \leftprotrusion A paragraph cell where the first character is protruded & Right \\
\end{tabular}

% Protrusion for specific text
\leftprotrusion{``Quoted text''} starts with proper margin alignment.

% Right protrusion (text must be in argument)
\rightprotrusion{Text ending with punctuation.}

% Prevent protrusion
\noprotrusion This line will not protrude.

% Prevent protrusion only if in horizontal mode
\noprotrusionifhmode Some text.

### \SetExtraKerning - Configure Additional Kerning

Source: https://context7.com/schlcht/microtype/llms.txt

Allows adding character-specific kerning independent of the font's built-in pair kerning. This feature is available for pdfTeX.

```APIDOC
## \SetExtraKerning - Configure Additional Kerning

### Description
Add character-specific kerning independent of font's built-in pair kerning (pdfTeX only).

### Method
LaTeX Command

### Endpoint
N/A (LaTeX Package Configuration)

### Parameters
#### Arguments
- **name** (string) - Optional - A name for the kerning configuration.
- **context** (string) - Optional - A context in which this kerning applies.
- **unit** (string) - Required - The unit of measurement for kerning (e.g., 'space', 'character').
- **encoding** (list of strings) - Required - The character encodings to which this applies.
- **family** (string) - Optional - The font family to which this applies.

### Request Example
```latex
\SetExtraKerning
   [ name    = french-default,
     context = french,
     unit    = space ]         % measure in terms of space width
   { encoding = {OT1,T1,LY1} }
   {
     :  = {1000, },            % full space before colon
     ;  = {500, },             % thin space before semicolon
     !  = {500, },             % thin space before exclamation
     ?  = {500, },             % thin space before question mark
   }
```

### \SetProtrusion - Configure Character Protrusion

Source: https://context7.com/schlcht/microtype/llms.txt

Defines protrusion amounts for individual characters in specific fonts to improve margin alignment.

```APIDOC
## \SetProtrusion

### Description
Define protrusion amounts for individual characters in specific fonts.

### Parameters
- **options** (optional) - Key-value pairs for configuration (e.g., name, load, factor, context).
- **font_selection** (required) - Font criteria (encoding, family, etc.).
- **protrusion_settings** (required) - Character-specific protrusion values in 1000ths of character width.
```

--------------------------------

### \textls and \lsstyle - Ad-hoc Letterspacing

Source: https://context7.com/schlcht/microtype/llms.txt

Applies letterspacing to specific text passages or groups regardless of global font configuration.

```APIDOC
## \textls and \lsstyle

### Description
Apply letterspacing to specific text passages.

### Parameters
- **amount** (optional) - Tracking amount in 1000ths of 1em.
- **text** (required) - The text to be letterspaced.
```

--------------------------------

### Ad-hoc Letterspacing with \textls and \lsstyle

Source: https://context7.com/schlcht/microtype/llms.txt

Apply letterspacing to specific text passages regardless of font configuration. \textls applies letterspacing with a default or custom amount, and its starred version prevents outer kerning. \lsstyle enables letterspacing for a group of text. Ligatures can be protected during letterspacing.

```latex
\documentclass{article}
\usepackage{microtype}

\begin{document}
% Basic letterspacing with default amount
\textls{LETTERSPACED TEXT}

% Custom letterspace amount (1000ths of 1em)
\textls[200]{More widely spaced}
\textls[-50]{Slightly compressed}

% No outer kerning (starred version) - useful for titles
\textls*{SECTION TITLE}

% Switch on letterspacing for rest of group
{\lsstyle This entire text is letterspaced until the group ends.}

% Combine with other formatting
\textls{\textsc{Letterspaced Small Caps}}

% In section titles (no outer kern preferred)
\section{\textls*{INTRODUCTION}}

% Protect specific ligatures while letterspacing
\textls{e\lslig{ff}ects}  % keeps ff ligature intact

\end{document}
```

--------------------------------

### Manual Protrusion

Source: https://context7.com/schlcht/microtype/llms.txt

Commands to manually control character protrusion at inner margins for tables, lists, or specific text blocks.

```APIDOC

### Control Ligatures with \DisableLigatures

Source: https://context7.com/schlcht/microtype/llms.txt

Disable ligatures for specific fonts, encodings, or individual characters. Useful for preventing unwanted ligature formation.

```latex
\documentclass{article}
\usepackage{microtype}

% Disable all ligatures for typewriter font
\DisableLigatures{encoding = T1, family = tt*}

% Disable specific ligatures only
\DisableLigatures[?,!]{encoding = T1}  % disable ?` and !` only

% Disable f-ligatures for roman font
\DisableLigatures[f]{encoding = T1, family = rm*}

\begin{document}
\texttt{--} prints as two dashes, not en-dash.

Normal text still has fi ligatures.

With [f] disabled: fi prints as f followed by i.
