This document expects some familiarity with Lama2 . To quickly get started with Lama2 , head over to Examples . On the other hand, if you are a developer and wish to learn more about the formal grammar underlying l2 , visit the Grammar section. Comments start with # \u00b6 Lines starting with # are comments and hence ignored altogether All HTTP Verbs supported - including the common GET/POST/PUT \u00b6 Fully supported: GET|HEAD|POST|PUT|DELETE|CONNECT|OPTIONS|TRACE|PATCH JSON is the default submission type, but MULTIPART is supported too \u00b6 varjson is a simpler syntax to specify flat JSONs \u00b6 varjson values are defined as follows: hello=world foo=bar The above results in a JSON submission of the form: { \"hello\": \"world\", \"foo\": \"bar\" } Nested JSON can simply be dumped at the end of the document \u00b6 The JSON recognition engine is quite lenient. It can deal with minor errors in the format (such as having single quotes instead of double quotes, trailing garbage, or an extra comma after the last element in an array,). POST https://httpbin.org/post { \"a\": \"b\", \"c\": \"d\" } MULTIPART allows both file uploads & the usual fields \u00b6 Example: POST MULTIPART http://localhost:8000/register userid=lince5 file@./helloworld.jpg Note The file path is relative to the request file. Cookies are sent as headers \u00b6 Cookies are specified in a Cookie header as follows: Cookie:'sessionid=foo;another-cookie=bar' API variables can be defined in apirequest.l2 \u00b6 L2 uses the variables declared inside the .l2 file and makes the request Example login.l2 : let REMOTE = \"httpbin.org\" let EMAIL = \"customer1@gmail.com\" --- POST ${REMOTE}/login { \"email\": \"${EMAIL}\", \"password\": \"customer1@gmail.com\" } Get Source Files API environment variables can be defined locally in l2.env \u00b6 l2.env is searched for, from the present directory and variables(local) are loaded from this file.

Container , error ) Method VarJSON behaves in two ways depending on whether `multipart` is true or not. If there is no multipart, then VarJSON tries to match one or more VarJSONPairs However, if there is multipart, we try to match zero or more VarJSON, followed by zero or more file fields (separated by `@`). If there is no match at all, we return a ParseError; otherwise the we return the parsed data. func (*Lama2Parser) VarJSONPair \u00b6 func ( p * Lama2Parser ) VarJSONPair () ( * gabs . Container , error ) VarJSONPair tries to match key and value separated by `=`. The key and value can either be a quoted string, or an unquoted VarJSON unquoted string. If there is no match for either, a ParseError is returned. func (*Lama2Parser) VarJSONUnquoted \u00b6 func ( p * Lama2Parser ) VarJSONUnquoted () ( * gabs . Container , error ) VarJSONUnquoted matches a string of characters other than `=` and returns them as a String type MinimalParser \u00b6 MinimalParser enforces concrete Types to have a Start() method, from which parsing process begins. In the present case, `Lama2Parser` adds up dozens of of methods to implement `.l2` syntax type MinimalParser interface { Start () ( * gabs . Container , error ) } type Parser \u00b6 Struct Parser stores information about the parsing process throughout. 1. Text: Incoming text is stored as an array of runes, to correctly handle unicode characters 2. Pos: Indicates the index position in Text which has already been scanned; starts with -1 3. TotalLen: Number of runes in the input 4. Pm: Composing an external MinimalParser (such as Lama2Parser) which builds upon Parser to provide the new language recognition capabilities 5. ruleMethodMap: Scans through Pm, and creates a mapping from method name to method value through reflection 6. LineNum: Number of normalized newlines found till now.

A good description of CharClass is available here: Read the section \"Processing Character Ranges\" at https://www.booleanworld.com/building-recursive-descent-parsers-definitive-guide/ func (*Parser) Init \u00b6 func ( p * Parser ) Init () Method Init creates the most important data stucture for parsing: ruleMethodMap. We use reflection to create a mapping of each Pm.\\<method_name> to \\<method_value> func (*Parser) Keyword \u00b6 func ( p * Parser ) Keyword ( kw string , eatWsStart bool , eatWsEnd bool , caseInsensitive bool ) ([] rune , error ) Method Keyword is a versatile; it can eat whitespace before/after the expected string, and it can do an optionally case insensitive match for the keyword func (*Parser) LookAhead \u00b6 func ( p * Parser ) LookAhead ( rules [] string ) bool func (*Parser) Match \u00b6 func ( p * Parser ) Match ( rules [] string ) ( * gabs . Container , error ) Method Match is the most important of all in the parser package. Match takes in a slice of rules (essentially method names), and then executes them one by one. On successful match, we return a gabs Container with `error` set to `nil` When a rule fails to match, we reset the scan position to initial position; moreover, we keep a continuous track of the farthest/longest match till present. The farthest match error is potentially the most useful error message to the user; thus, for error report, Match returns the farthest matching error func (*Parser) MatchUntil \u00b6 func ( p * Parser ) MatchUntil ( end string ) ( * gabs . Container , error ) func (*Parser) Parse \u00b6 func ( p * Parser ) Parse ( text string ) ( * gabs .

The Start() method proceeds to process the rune version of data func (*Parser) SetText \u00b6 func ( p * Parser ) SetText ( text string ) Method SetText is a utility used primarily in testing, when we don't want to call Start() automatically as in Parse func (*Parser) SplitCharRanges \u00b6 func ( p * Parser ) SplitCharRanges ( charClass string ) ([] string , error ) func (*Parser) Start \u00b6 func ( p * Parser ) Start () * gabs .
