See LICENSE. + +local M = {} + +--[=[ This comment is for LuaDoc. +--- +-- Lexes Scintilla documents with Lua and LPeg. +-- +-- ## Overview +-- +-- Lexers highlight the syntax of source code. Scintilla (the editing component +-- behind [Textadept][] and [SciTE][]) traditionally uses static, compiled C++ +-- lexers which are notoriously difficult to create and/or extend. On the other +-- hand, Lua makes it easy to to rapidly create new lexers, extend existing +-- ones, and embed lexers within one another. Lua lexers tend to be more +-- readable than C++ lexers too. +-- +-- Lexers are Parsing Expression Grammars, or PEGs, composed with the Lua +-- [LPeg library][]. The following table comes from the LPeg documentation and +-- summarizes all you need to know about constructing basic LPeg patterns. This +-- module provides convenience functions for creating and working with other +-- more advanced patterns and concepts. +-- +-- Operator | Description +-- ---------------------|------------ +-- `lpeg.P(string)` | Matches `string` literally. +-- `lpeg.P(`_`n`_`)` | Matches exactly _`n`_ characters. +-- `lpeg.S(string)` | Matches any character in set `string`. +-- `lpeg.R("`_`xy`_`")` | Matches any character between range `x` and `y`. +-- `patt^`_`n`_ | Matches at least _`n`_ repetitions of `patt`. +-- `patt^-`_`n`_ | Matches at most _`n`_ repetitions of `patt`. +-- `patt1 * patt2` | Matches `patt1` followed by `patt2`. +-- `patt1 + patt2` | Matches `patt1` or `patt2` (ordered choice). +-- `patt1 - patt2` | Matches `patt1` if `patt2` does not match. +-- `-patt` | Equivalent to `("" - patt)`. +-- `#patt` | Matches `patt` but consumes no input. +-- +-- The first part of this document deals with rapidly constructing a simple +-- lexer. The next part deals with more advanced techniques, such as custom +-- coloring and embedding lexers within one another. Following that is a +-- discussion about code folding, or being able to tell Scintilla which code +-- blocks are "foldable" (temporarily hideable from view). After that are +-- instructions on how to use LPeg lexers with the aforementioned Textadept and +-- SciTE editors. Finally there are comments on lexer performance and +-- limitations. +-- +-- [LPeg library]: http://www.inf.puc-rio.br/~roberto/lpeg/lpeg.html +-- [Textadept]: http://foicica.com/textadept +-- [SciTE]: http://scintilla.org/SciTE.html +-- +-- ## Lexer Basics +-- +-- The *lexers/* directory contains all lexers, including your new one. Before +-- attempting to write one from scratch though, first determine if your +-- programming language is similar to any of the 80+ languages supported. If so, +-- you may be able to copy and modify that lexer, saving some time and effort. +-- The filename of your lexer should be the name of your programming language in +-- lower case followed by a *.lua* extension. For example, a new Lua lexer has +-- the name *lua.lua*. +-- +-- Note: Try to refrain from using one-character language names like "b", "c", +-- or "d". For example, Scintillua uses "b_lang", "cpp", and "dmd", +-- respectively. +-- +-- ### New Lexer Template +-- +-- There is a *lexers/template.txt* file that contains a simple template for a +-- new lexer. Feel free to use it, replacing the '?'s with the name of your +-- lexer: +-- +-- -- ? LPeg lexer. +-- +-- local l = require('lexer') +-- local token, word_match = l.token, l.word_match +-- local P, R, S = lpeg.P, lpeg.R, lpeg.S +-- +-- local M = {_NAME = '?'} +-- +-- -- Whitespace. +-- local ws = token(l.WHITESPACE, l.space^1) +-- +-- M._rules = { +-- {'whitespace', ws}, +-- } +-- +-- M._tokenstyles = { +-- +-- } +-- +-- return M +-- +-- The first 4 lines of code simply define often used convenience variables. The +-- 5th and last lines define and return the lexer object Scintilla uses; they +-- are very important and must be part of every lexer. The sixth line defines +-- something called a "token", an essential building block of lexers. You will +-- learn about tokens shortly. The rest of the code defines a set of grammar +-- rules and token styles. You will learn about those later. Note, however, the +-- `M.` prefix in front of `_rules` and `_tokenstyles`: not only do these tables +-- belong to their respective lexers, but any non-local variables need the `M.` +-- prefix too so-as not to affect Lua's global environment. All in all, this is +-- a minimal, working lexer that you can build on. +-- +-- ### Tokens +-- +-- Take a moment to think about your programming language's structure. What kind +-- of key elements does it have? In the template shown earlier, one predefined +-- element all languages have is whitespace. Your language probably also has +-- elements like comments, strings, and keywords. Lexers refer to these elements +-- as "tokens". Tokens are the fundamental "building blocks" of lexers. Lexers +-- break down source code into tokens for coloring, which results in the syntax +-- highlighting familiar to you. It is up to you how specific your lexer is when +-- it comes to tokens. Perhaps only distinguishing between keywords and +-- identifiers is necessary, or maybe recognizing constants and built-in +-- functions, methods, or libraries is desirable. The Lua lexer, for example, +-- defines 11 tokens: whitespace, comments, strings, numbers, keywords, built-in +-- functions, constants, built-in libraries, identifiers, labels, and operators. +-- Even though constants, built-in functions, and built-in libraries are subsets +-- of identifiers, Lua programmers find it helpful for the lexer to distinguish +-- between them all. It is perfectly acceptable to just recognize keywords and +-- identifiers. +-- +-- In a lexer, tokens consist of a token name and an LPeg pattern that matches a +-- sequence of characters recognized as an instance of that token. Create tokens +-- using the [`lexer.token()`]() function. Let us examine the "whitespace" token +-- defined in the template shown earlier: +-- +-- local ws = token(l.WHITESPACE, l.space^1) +-- +-- At first glance, the first argument does not appear to be a string name and +-- the second argument does not appear to be an LPeg pattern. Perhaps you +-- expected something like: +-- +-- local ws = token('whitespace', S('\t\v\f\n\r ')^1) +-- +-- The `lexer` (`l`) module actually provides a convenient list of common token +-- names and common LPeg patterns for you to use. Token names include +-- [`lexer.DEFAULT`](), [`lexer.WHITESPACE`](), [`lexer.COMMENT`](), +-- [`lexer.STRING`](), [`lexer.NUMBER`](), [`lexer.KEYWORD`](), +-- [`lexer.IDENTIFIER`](), [`lexer.OPERATOR`](), [`lexer.ERROR`](), +-- [`lexer.PREPROCESSOR`](), [`lexer.CONSTANT`](), [`lexer.VARIABLE`](), +-- [`lexer.FUNCTION`](), [`lexer.CLASS`](), [`lexer.TYPE`](), [`lexer.LABEL`](), +-- [`lexer.REGEX`](), and [`lexer.EMBEDDED`](). Patterns include +-- [`lexer.any`](), [`lexer.ascii`](), [`lexer.extend`](), [`lexer.alpha`](), +-- [`lexer.digit`](), [`lexer.alnum`](), [`lexer.lower`](), [`lexer.upper`](), +-- [`lexer.xdigit`](), [`lexer.cntrl`](), [`lexer.graph`](), [`lexer.print`](), +-- [`lexer.punct`](), [`lexer.space`](), [`lexer.newline`](), +-- [`lexer.nonnewline`](), [`lexer.nonnewline_esc`](), [`lexer.dec_num`](), +-- [`lexer.hex_num`](), [`lexer.oct_num`](), [`lexer.integer`](), +-- [`lexer.float`](), and [`lexer.word`](). You may use your own token names if +-- none of the above fit your language, but an advantage to using predefined +-- token names is that your lexer's tokens will inherit the universal syntax +-- highlighting color theme used by your text editor. +-- +-- #### Example Tokens +-- +-- So, how might you define other tokens like comments, strings, and keywords? +-- Here are some examples. +-- +-- **Comments** +-- +-- Line-style comments with a prefix character(s) are easy to express with LPeg: +-- +-- local shell_comment = token(l.COMMENT, '#' * l.nonnewline^0) +-- local c_line_comment = token(l.COMMENT, '//' * l.nonnewline_esc^0) +-- +-- The comments above start with a '#' or "//" and go to the end of the line. +-- The second comment recognizes the next line also as a comment if the current +-- line ends with a '\' escape character. +-- +-- C-style "block" comments with a start and end delimiter are also easy to +-- express: +-- +-- local c_comment = token(l.COMMENT, '/*' * (l.any - '*/')^0 * P('*/')^-1) +-- +-- This comment starts with a "/\*" sequence and contains anything up to and +-- including an ending "\*/" sequence. The ending "\*/" is optional so the lexer +-- can recognize unfinished comments as comments and highlight them properly. +-- +-- **Strings** +-- +-- It is tempting to think that a string is not much different from the block +-- comment shown above in that both have start and end delimiters: +-- +-- local dq_str = '"' * (l.any - '"')^0 * P('"')^-1 +-- local sq_str = "'" * (l.any - "'")^0 * P("'")^-1 +-- local simple_string = token(l.STRING, dq_str + sq_str) +-- +-- However, most programming languages allow escape sequences in strings such +-- that a sequence like "\\"" in a double-quoted string indicates that the +-- '"' is not the end of the string. The above token incorrectly matches +-- such a string. Instead, use the [`lexer.delimited_range()`]() convenience +-- function. +-- +-- local dq_str = l.delimited_range('"') +-- local sq_str = l.delimited_range("'") +-- local string = token(l.STRING, dq_str + sq_str) +-- +-- In this case, the lexer treats '\' as an escape character in a string +-- sequence. +-- +-- **Keywords** +-- +-- Instead of matching _n_ keywords with _n_ `P('keyword_`_`n`_`')` ordered +-- choices, use another convenience function: [`lexer.word_match()`](). It is +-- much easier and more efficient to write word matches like: +-- +-- local keyword = token(l.KEYWORD, l.word_match{ +-- 'keyword_1', 'keyword_2', ..., 'keyword_n' +-- }) +-- +-- local case_insensitive_keyword = token(l.KEYWORD, l.word_match({ +-- 'KEYWORD_1', 'keyword_2', ..., 'KEYword_n' +-- }, nil, true)) +-- +-- local hyphened_keyword = token(l.KEYWORD, l.word_match({ +-- 'keyword-1', 'keyword-2', ..., 'keyword-n' +-- }, '-')) +-- +-- By default, characters considered to be in keywords are in the set of +-- alphanumeric characters and underscores. The last token demonstrates how to +-- allow '-' (hyphen) characters to be in keywords as well. +-- +-- **Numbers** +-- +-- Most programming languages have the same format for integer and float tokens, +-- so it might be as simple as using a couple of predefined LPeg patterns: +-- +-- local number = token(l.NUMBER, l.float + l.integer) +-- +-- However, some languages allow postfix characters on integers. +-- +-- local integer = P('-')^-1 * (l.dec_num * S('lL')^-1) +-- local number = token(l.NUMBER, l.float + l.hex_num + integer) +-- +-- Your language may need other tweaks, but it is up to you how fine-grained you +-- want your highlighting to be. After all, you are not writing a compiler or +-- interpreter! +-- +-- ### Rules +-- +-- Programming languages have grammars, which specify valid token structure. For +-- example, comments usually cannot appear within a string. Grammars consist of +-- rules, which are simply combinations of tokens. Recall from the lexer +-- template the `_rules` table, which defines all the rules used by the lexer +-- grammar: +-- +-- M._rules = { +-- {'whitespace', ws}, +-- } +-- +-- Each entry in a lexer's `_rules` table consists of a rule name and its +-- associated pattern. Rule names are completely arbitrary and serve only to +-- identify and distinguish between different rules. Rule order is important: if +-- text does not match the first rule, the lexer tries the second rule, and so +-- on. This simple grammar says to match whitespace tokens under a rule named +-- "whitespace". +-- +-- To illustrate the importance of rule order, here is an example of a +-- simplified Lua grammar: +-- +-- M._rules = { +-- {'whitespace', ws}, +-- {'keyword', keyword}, +-- {'identifier', identifier}, +-- {'string', string}, +-- {'comment', comment}, +-- {'number', number}, +-- {'label', label}, +-- {'operator', operator}, +-- } +-- +-- Note how identifiers come after keywords. In Lua, as with most programming +-- languages, the characters allowed in keywords and identifiers are in the same +-- set (alphanumerics plus underscores). If the lexer specified the "identifier" +-- rule before the "keyword" rule, all keywords would match identifiers and thus +-- incorrectly highlight as identifiers instead of keywords. The same idea +-- applies to function, constant, etc. tokens that you may want to distinguish +-- between: their rules should come before identifiers. +-- +-- So what about text that does not match any rules? For example in Lua, the '!' +-- character is meaningless outside a string or comment. Normally the lexer +-- skips over such text. If instead you want to highlight these "syntax errors", +-- add an additional end rule: +-- +-- M._rules = { +-- {'whitespace', ws}, +-- {'error', token(l.ERROR, l.any)}, +-- } +-- +-- This identifies and highlights any character not matched by an existing +-- rule as an `lexer.ERROR` token. +-- +-- Even though the rules defined in the examples above contain a single token, +-- rules may consist of multiple tokens. For example, a rule for an HTML tag +-- could consist of a tag token followed by an arbitrary number of attribute +-- tokens, allowing the lexer to highlight all tokens separately. The rule might +-- look something like this: +-- +-- {'tag', tag_start * (ws * attributes)^0 * tag_end^-1} +-- +-- Note however that lexers with complex rules like these are more prone to lose +-- track of their state. +-- +-- ### Summary +-- +-- Lexers primarily consist of tokens and grammar rules. At your disposal are a +-- number of convenience patterns and functions for rapidly creating a lexer. If +-- you choose to use predefined token names for your tokens, you do not have to +-- define how the lexer highlights them. The tokens will inherit the default +-- syntax highlighting color theme your editor uses. +-- +-- ## Advanced Techniques +-- +-- ### Styles and Styling +-- +-- The most basic form of syntax highlighting is assigning different colors to +-- different tokens. Instead of highlighting with just colors, Scintilla allows +-- for more rich highlighting, or "styling", with different fonts, font sizes, +-- font attributes, and foreground and background colors, just to name a few. +-- The unit of this rich highlighting is called a "style". Styles are simply +-- strings of comma-separated property settings. By default, lexers associate +-- predefined token names like `lexer.WHITESPACE`, `lexer.COMMENT`, +-- `lexer.STRING`, etc. with particular styles as part of a universal color +-- theme. These predefined styles include [`lexer.STYLE_CLASS`](), +-- [`lexer.STYLE_COMMENT`](), [`lexer.STYLE_CONSTANT`](), +-- [`lexer.STYLE_ERROR`](), [`lexer.STYLE_EMBEDDED`](), +-- [`lexer.STYLE_FUNCTION`](), [`lexer.STYLE_IDENTIFIER`](), +-- [`lexer.STYLE_KEYWORD`](), [`lexer.STYLE_LABEL`](), [`lexer.STYLE_NUMBER`](), +-- [`lexer.STYLE_OPERATOR`](), [`lexer.STYLE_PREPROCESSOR`](), +-- [`lexer.STYLE_REGEX`](), [`lexer.STYLE_STRING`](), [`lexer.STYLE_TYPE`](), +-- [`lexer.STYLE_VARIABLE`](), and [`lexer.STYLE_WHITESPACE`](). Like with +-- predefined token names and LPeg patterns, you may define your own styles. At +-- their core, styles are just strings, so you may create new ones and/or modify +-- existing ones. Each style consists of the following comma-separated settings: +-- +-- Setting | Description +-- ---------------|------------ +-- font:_name_ | The name of the font the style uses. +-- size:_int_ | The size of the font the style uses. +-- [not]bold | Whether or not the font face is bold. +-- [not]italics | Whether or not the font face is italic. +-- [not]underlined| Whether or not the font face is underlined. +-- fore:_color_ | The foreground color of the font face. +-- back:_color_ | The background color of the font face. +-- [not]eolfilled | Does the background color extend to the end of the line? +-- case:_char_ | The case of the font ('u': upper, 'l': lower, 'm': normal). +-- [not]visible | Whether or not the text is visible. +-- [not]changeable| Whether the text is changeable or read-only. +-- +-- Specify font colors in either "#RRGGBB" format, "0xBBGGRR" format, or the +-- decimal equivalent of the latter. As with token names, LPeg patterns, and +-- styles, there is a set of predefined color names, but they vary depending on +-- the current color theme in use. Therefore, it is generally not a good idea to +-- manually define colors within styles in your lexer since they might not fit +-- into a user's chosen color theme. Try to refrain from even using predefined +-- colors in a style because that color may be theme-specific. Instead, the best +-- practice is to either use predefined styles or derive new color-agnostic +-- styles from predefined ones. For example, Lua "longstring" tokens use the +-- existing `lexer.STYLE_STRING` style instead of defining a new one. +-- +-- #### Example Styles +-- +-- Defining styles is pretty straightforward. An empty style that inherits the +-- default theme settings is simply an empty string: +-- +-- local style_nothing = '' +-- +-- A similar style but with a bold font face looks like this: +-- +-- local style_bold = 'bold' +-- +-- If you want the same style, but also with an italic font face, define the new +-- style in terms of the old one: +-- +-- local style_bold_italic = style_bold..',italics' +-- +-- This allows you to derive new styles from predefined ones without having to +-- rewrite them. This operation leaves the old style unchanged. Thus if you +-- had a "static variable" token whose style you wanted to base off of +-- `lexer.STYLE_VARIABLE`, it would probably look like: +-- +-- local style_static_var = l.STYLE_VARIABLE..',italics' +-- +-- The color theme files in the *lexers/themes/* folder give more examples of +-- style definitions. +-- +-- ### Token Styles +-- +-- Lexers use the `_tokenstyles` table to assign tokens to particular styles. +-- Recall the token definition and `_tokenstyles` table from the lexer template: +-- +-- local ws = token(l.WHITESPACE, l.space^1) +-- +-- ... +-- +-- M._tokenstyles = { +-- +-- } +-- +-- Why is a style not assigned to the `lexer.WHITESPACE` token? As mentioned +-- earlier, lexers automatically associate tokens that use predefined token +-- names with a particular style. Only tokens with custom token names need +-- manual style associations. As an example, consider a custom whitespace token: +-- +-- local ws = token('custom_whitespace', l.space^1) +-- +-- Assigning a style to this token looks like: +-- +-- M._tokenstyles = { +-- custom_whitespace = l.STYLE_WHITESPACE +-- } +-- +-- Do not confuse token names with rule names. They are completely different +-- entities. In the example above, the lexer assigns the "custom_whitespace" +-- token the existing style for `WHITESPACE` tokens. If instead you want to +-- color the background of whitespace a shade of grey, it might look like: +-- +-- local custom_style = l.STYLE_WHITESPACE..',back:$(color.grey)' +-- M._tokenstyles = { +-- custom_whitespace = custom_style +-- } +-- +-- Notice that the lexer peforms Scintilla/SciTE-style "$()" property expansion. +-- You may also use "%()". Remember to refrain from assigning specific colors in +-- styles, but in this case, all user color themes probably define the +-- "color.grey" property. +-- +-- ### Line Lexers +-- +-- By default, lexers match the arbitrary chunks of text passed to them by +-- Scintilla. These chunks may be a full document, only the visible part of a +-- document, or even just portions of lines. Some lexers need to match whole +-- lines. For example, a lexer for the output of a file "diff" needs to know if +-- the line started with a '+' or '-' and then style the entire line +-- accordingly. To indicate that your lexer matches by line, use the +-- `_LEXBYLINE` field: +-- +-- M._LEXBYLINE = true +-- +-- Now the input text for the lexer is a single line at a time. Keep in mind +-- that line lexers do not have the ability to look ahead at subsequent lines. +-- +-- ### Embedded Lexers +-- +-- Lexers embed within one another very easily, requiring minimal effort. In the +-- following sections, the lexer being embedded is called the "child" lexer and +-- the lexer a child is being embedded in is called the "parent". For example, +-- consider an HTML lexer and a CSS lexer. Either lexer stands alone for styling +-- their respective HTML and CSS files. However, CSS can be embedded inside +-- HTML. In this specific case, the CSS lexer is the "child" lexer with the HTML +-- lexer being the "parent". Now consider an HTML lexer and a PHP lexer. This +-- sounds a lot like the case with CSS, but there is a subtle difference: PHP +-- _embeds itself_ into HTML while CSS is _embedded in_ HTML. This fundamental +-- difference results in two types of embedded lexers: a parent lexer that +-- embeds other child lexers in it (like HTML embedding CSS), and a child lexer +-- that embeds itself within a parent lexer (like PHP embedding itself in HTML). +-- +-- #### Parent Lexer +-- +-- Before embedding a child lexer into a parent lexer, the parent lexer needs to +-- load the child lexer. This is done with the [`lexer.load()`]() function. For +-- example, loading the CSS lexer within the HTML lexer looks like: +-- +-- local css = l.load('css') +-- +-- The next part of the embedding process is telling the parent lexer when to +-- switch over to the child lexer and when to switch back. The lexer refers to +-- these indications as the "start rule" and "end rule", respectively, and are +-- just LPeg patterns. Continuing with the HTML/CSS example, the transition from +-- HTML to CSS is when the lexer encounters a "style" tag with a "type" +-- attribute whose value is "text/css": +-- +-- local css_tag = P('<style') * P(function(input, index) +-- if input:find('^[^>]+type="text/css"', index) then +-- return index +-- end +-- end) +-- +-- This pattern looks for the beginning of a "style" tag and searches its +-- attribute list for the text "`type="text/css"`". (In this simplified example, +-- the Lua pattern does not consider whitespace between the '=' nor does it +-- consider that using single quotes is valid.) If there is a match, the +-- functional pattern returns a value instead of `nil`. In this case, the value +-- returned does not matter because we ultimately want to style the "style" tag +-- as an HTML tag, so the actual start rule looks like this: +-- +-- local css_start_rule = #css_tag * tag +-- +-- Now that the parent knows when to switch to the child, it needs to know when +-- to switch back. In the case of HTML/CSS, the switch back occurs when the +-- lexer encounters an ending "style" tag, though the lexer should still style +-- the tag as an HTML tag: +-- +-- local css_end_rule = #P('</style>') * tag +-- +-- Once the parent loads the child lexer and defines the child's start and end +-- rules, it embeds the child with the [`lexer.embed_lexer()`]() function: +-- +-- l.embed_lexer(M, css, css_start_rule, css_end_rule) +-- +-- The first parameter is the parent lexer object to embed the child in, which +-- in this case is `M`. The other three parameters are the child lexer object +-- loaded earlier followed by its start and end rules. +-- +-- #### Child Lexer +-- +-- The process for instructing a child lexer to embed itself into a parent is +-- very similar to embedding a child into a parent: first, load the parent lexer +-- into the child lexer with the [`lexer.load()`]() function and then create +-- start and end rules for the child lexer. However, in this case, swap the +-- lexer object arguments to [`lexer.embed_lexer()`](). For example, in the PHP +-- lexer: +-- +-- local html = l.load('html') +-- local php_start_rule = token('php_tag', '<?php ') +-- local php_end_rule = token('php_tag', '?>') +-- l.embed_lexer(html, M, php_start_rule, php_end_rule) +-- +-- ## Code Folding +-- +-- When reading source code, it is occasionally helpful to temporarily hide +-- blocks of code like functions, classes, comments, etc. This is the concept of +-- "folding". In the Textadept and SciTE editors for example, little indicators +-- in the editor margins appear next to code that can be folded at places called +-- "fold points". When the user clicks an indicator, the editor hides the code +-- associated with the indicator until the user clicks the indicator again. The +-- lexer specifies these fold points and what code exactly to fold. +-- +-- The fold points for most languages occur on keywords or character sequences. +-- Examples of fold keywords are "if" and "end" in Lua and examples of fold +-- character sequences are '{', '}', "/\*", and "\*/" in C for code block and +-- comment delimiters, respectively. However, these fold points cannot occur +-- just anywhere. For example, lexers should not recognize fold keywords that +-- appear within strings or comments. The lexer's `_foldsymbols` table allows +-- you to conveniently define fold points with such granularity. For example, +-- consider C: +-- +-- M._foldsymbols = { +-- [l.OPERATOR] = {['{'] = 1, ['}'] = -1}, +-- [l.COMMENT] = {['/*'] = 1, ['*/'] = -1}, +-- _patterns = {'[{}]', '/%*', '%*/'} +-- } +-- +-- The first assignment states that any '{' or '}' that the lexer recognized as +-- an `lexer.OPERATOR` token is a fold point. The integer `1` indicates the +-- match is a beginning fold point and `-1` indicates the match is an ending +-- fold point. Likewise, the second assignment states that any "/\*" or "\*/" +-- that the lexer recognizes as part of a `lexer.COMMENT` token is a fold point. +-- The lexer does not consider any occurences of these characters outside their +-- defined tokens (such as in a string) as fold points. Finally, every +-- `_foldsymbols` table must have a `_patterns` field that contains a list of +-- [Lua patterns][] that match fold points. If the lexer encounters text that +-- matches one of those patterns, the lexer looks up the matched text in its +-- token's table to determine whether or not the text is a fold point. In the +-- example above, the first Lua pattern matches any '{' or '}' characters. When +-- the lexer comes across one of those characters, it checks if the match is an +-- `lexer.OPERATOR` token. If so, the lexer identifies the match as a fold +-- point. The same idea applies for the other patterns. (The '%' is in the other +-- patterns because '\*' is a special character in Lua patterns that needs +-- escaping.) How do you specify fold keywords? Here is an example for Lua: +-- +-- M._foldsymbols = { +-- [l.KEYWORD] = { +-- ['if'] = 1, ['do'] = 1, ['function'] = 1, +-- ['end'] = -1, ['repeat'] = 1, ['until'] = -1 +-- }, +-- _patterns = {'%l+'} +-- } +-- +-- Any time the lexer encounters a lower case word, if that word is a +-- `lexer.KEYWORD` token and in the associated list of fold points, the lexer +-- identifies the word as a fold point. +-- +-- If your lexer needs to do some additional processing to determine if a match +-- is a fold point, assign a function that returns an integer. Returning `1` or +-- `-1` indicates the match is a fold point. Returning `0` indicates it is not. +-- For example: +-- +-- local function fold_strange_token(text, pos, line, s, match) +-- if ... then +-- return 1 -- beginning fold point +-- elseif ... then +-- return -1 -- ending fold point +-- end +-- return 0 +-- end +-- +-- M._foldsymbols = { +-- ['strange_token'] = {['|'] = fold_strange_token}, +-- _patterns = {'|'} +-- } +-- +-- Any time the lexer encounters a '|' that is a "strange_token", it calls the +-- `fold_strange_token` function to determine if '|' is a fold point. The lexer +-- calls these functions with the following arguments: the text to identify fold +-- points in, the beginning position of the current line in the text to fold, +-- the current line's text, the position in the current line the matched text +-- starts at, and the matched text itself. +-- +-- [Lua patterns]: http://www.lua.org/manual/5.2/manual.html#6.4.1 +-- +-- ### Fold by Indentation +-- +-- Some languages have significant whitespace and/or no delimiters that indicate +-- fold points. If your lexer falls into this category and you would like to +-- mark fold points based on changes in indentation, use the +-- `_FOLDBYINDENTATION` field: +-- +-- M._FOLDBYINDENTATION = true +-- +-- ## Using Lexers +-- +-- ### Textadept +-- +-- Put your lexer in your *~/.textadept/lexers/* directory so you do not +-- overwrite it when upgrading Textadept. Also, lexers in this directory +-- override default lexers. Thus, Textadept loads a user *lua* lexer instead of +-- the default *lua* lexer. This is convenient for tweaking a default lexer to +-- your liking. Then add a [file type][] for your lexer if necessary. +-- +-- [file type]: _M.textadept.file_types.html +-- +-- ### SciTE +-- +-- Create a *.properties* file for your lexer and `import` it in either your +-- *SciTEUser.properties* or *SciTEGlobal.properties*. The contents of the +-- *.properties* file should contain: +-- +-- file.patterns.[lexer_name]=[file_patterns] +-- lexer.$(file.patterns.[lexer_name])=[lexer_name] +-- +-- where `[lexer_name]` is the name of your lexer (minus the *.lua* extension) +-- and `[file_patterns]` is a set of file extensions to use your lexer for. +-- +-- Please note that Lua lexers ignore any styling information in *.properties* +-- files. Your theme file in the *lexers/themes/* directory contains styling +-- information. +-- +-- ## Considerations +-- +-- ### Performance +-- +-- There might be some slight overhead when initializing a lexer, but loading a +-- file from disk into Scintilla is usually more expensive. On modern computer +-- systems, I see no difference in speed between LPeg lexers and Scintilla's C++ +-- ones. Optimize lexers for speed by re-arranging rules in the `_rules` table +-- so that the most common rules match first. Do keep in mind that order matters +-- for similar rules. +-- +-- ### Limitations +-- +-- Embedded preprocessor languages like PHP cannot completely embed in their +-- parent languages in that the parent's tokens do not support start and end +-- rules. This mostly goes unnoticed, but code like +-- +-- <div id="<?php echo $id; ?>"> +-- +-- or +-- +-- <div <?php if ($odd) { echo 'class="odd"'; } ?>> +-- +-- will not style correctly. +-- +-- ### Troubleshooting +-- +-- Errors in lexers can be tricky to debug. Lexers print Lua errors to +-- `io.stderr` and `_G.print()` statements to `io.stdout`. Running your editor +-- from a terminal is the easiest way to see errors as they occur. +-- +-- ### Risks +-- +-- Poorly written lexers have the ability to crash Scintilla (and thus its +-- containing application), so unsaved data might be lost. However, I have only +-- observed these crashes in early lexer development, when syntax errors or +-- pattern errors are present. Once the lexer actually starts styling text +-- (either correctly or incorrectly, it does not matter), I have not observed +-- any crashes. +-- +-- ### Acknowledgements +-- +-- Thanks to Peter Odding

A value of `1` indicates a beginning fold +-- point and a value of `-1` indicates an ending fold point.

This field +-- is only necessary to disambiguate a proxy lexer that loaded parent and +-- child lexers for embedding and ended up having multiple parents loaded. +-- @field _RULES A map of rule name keys with their associated LPeg pattern +-- values for the lexer. +-- This is constructed from the lexer's `_rules` table and accessible to other +-- lexers for embedded lexer applications like modifying parent or child +-- rules. +-- @field _LEXBYLINE Indicates the lexer can only process one whole line of text +-- (instead of an arbitrary chunk of text) at a time. +-- The default value is `false`.
