Move all lua related files to lua/ subfolder
Also remove the lexers sub directory from the Lua search path.
As a result we attempt to open fewer files during startup:
$ strace -e open -o log ./vis +q config.h && wc -l log
In order to avoid having to modifiy all lexers which `require('lexer')`
we instead place a symlink in the top level directory.
$ ./configure --disable-lua
$ rm -rf lua
Should result in a source tree with most lua specifc functionality
removed.

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 "c", "d", --- or "r". For example, Scintillua uses "ansi_c", "dmd", and "rstats", --- 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 3 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. --- weight:_int_ | The weight or boldness of a font, between 1 and 999. --- [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) --- --- ### Lexers with Complex State --- --- A vast majority of lexers are not stateful and can operate on any chunk of --- text in a document. However, there may be rare cases where a lexer does need --- to keep track of some sort of persistent state. Rather than using `lpeg.P` --- function patterns that set state variables, it is recommended to make use of --- Scintilla's built-in, per-line state integers via [`lexer.line_state`](). It --- was designed to accommodate up to 32 bit flags for tracking state. --- [`lexer.line_from_position()`]() will return the line for any position given --- to an `lpeg.P` function pattern. (Any positions derived from that position --- argument will also work.) --- --- Writing stateful lexers is beyond the scope of this document. --- --- ## 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

When the lexer encounters text that matches --- one of those patterns, the matched text is looked up in its token's table --- to determine whether or not it is a fold point. --- @field _fold If this function exists in the lexer, it is called for folding --- the document instead of using `_foldsymbols` or indentation. --- @field _lexer The parent lexer object whose rules should be used. 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`. Line lexers cannot look ahead to subsequent --- lines. --- @field _FOLDBYINDENTATION Declares the lexer does not define fold points and --- that fold points should be calculated based on changes in indentation. --- @class table --- @name lexer -local lexer -]] - -return M diff --git a/lexers/lilypond.lua b/lexers/lilypond.lua deleted file mode 100644 index f5af771..0000000 --- a/lexers/lilypond.lua +++ /dev/null @@ -1,40 +0,0 @@ --- Copyright 2006-2013 Robert Gieseke.
