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' Environment Variables \u00b6 API variables can be defined in apirequest.l2 \u00b6 Variables are declared within the JS processor block and serve as dynamic placeholders for data used in API requests. By utilizing these variables, L2 enables flexibility and reusability in defining API endpoints and data payloads. 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 provides a convenient way to define environment variables through the l2.env file. This file is automatically searched for in the present directory, and its contents are loaded to create a set of variables (local). In the l2.env file, you can specify environment-specific values for variables used in your L2 scripts, such as URLs, authentication tokens, or any other data that may vary depending on the environment in which the API requests are executed. Go to Example Get Source File API environment variables can be defined at project root using l2config.env \u00b6 The l2config.env file serves as a centralized storage for environment variables located at the project root, streamlining the management of configuration settings across all L2 scripts. With this file present, every L2 script within the project automatically inherits the defined variables, effectively eliminating the necessity to duplicate configurations in individual subdirectories using l2.env . The search for l2config.env extends from the present directory up to the root directory ( / ). During this process, the variables defined in the root file are loaded and made available for use in all relevant scripts. This approach significantly enhances efficiency and maintainability, as it ensures consistent settings throughout the project while reducing redundancy in configuration data. Go to Example Get Source File If l2config.env (root) variables are redeclared in l2.env (local) \u00b6 In situations where both root and local variables share the same variable name, the local variable takes precedence over the root variable. This behavior remains consistent, even if both l2config.env (root) and l2.env (local) files reside in the same directory. The local variable's value will always be considered over the root variable, ensuring that specific configurations defined at the local level effectively override any corresponding settings present in the root file. This approach provides developers with granular control and flexibility in tailoring environment variables to suit specific needs within different parts of the project while maintaining the overall structure and organization of configuration settings. Go to Example Get Source File The environment file can load results of commands \u00b6 Use the backtick notation \\ command`` to place the results of commands into environment variables: export PHOTO=`base64 image.jpeg` One can load the PHOTO variable in API files. Chain requests through Javascript blocks \u00b6 Lama2 supports plain Javascript (JS) blocks as a glue for manipulating responses and passing on values to later stages. At a higher level, a chain of requests may look like: Javascript 1 --- L2 Request 1 --- Javscript 2 --- L2 Request 2 The triple-dash ( --- ) separator is mandatory. The special variable result contains the response from previous stages. For example, in the above case, Javascript 2 can access the response from L2 Request 1 through the result variable.

The special variable result contains the response from previous stages. For example, in the above case, Javascript 2 can access the response from L2 Request 1 through the result variable.

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' Environment Variables \u00b6 API variables can be defined in apirequest.l2 \u00b6 Variables are declared within the JS processor block and serve as dynamic placeholders for data used in API requests. By utilizing these variables, L2 enables flexibility and reusability in defining API endpoints and data payloads. 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 provides a convenient way to define environment variables through the l2.env file. This file is automatically searched for in the present directory, and its contents are loaded to create a set of variables (local). In the l2.env file, you can specify environment-specific values for variables used in your L2 scripts, such as URLs, authentication tokens, or any other data that may vary depending on the environment in which the API requests are executed. Go to Example Get Source File API environment variables can be defined at project root using l2config.env \u00b6 The l2config.env file serves as a centralized storage for environment variables located at the project root, streamlining the management of configuration settings across all L2 scripts. With this file present, every L2 script within the project automatically inherits the defined variables, effectively eliminating the necessity to duplicate configurations in individual subdirectories using l2.env . The search for l2config.env extends from the present directory up to the root directory ( / ). During this process, the variables defined in the root file are loaded and made available for use in all relevant scripts. This approach significantly enhances efficiency and maintainability, as it ensures consistent settings throughout the project while reducing redundancy in configuration data. Go to Example Get Source File If l2config.env (root) variables are redeclared in l2.env (local) \u00b6 In situations where both root and local variables share the same variable name, the local variable takes precedence over the root variable. This behavior remains consistent, even if both l2config.env (root) and l2.env (local) files reside in the same directory. The local variable's value will always be considered over the root variable, ensuring that specific configurations defined at the local level effectively override any corresponding settings present in the root file. This approach provides developers with granular control and flexibility in tailoring environment variables to suit specific needs within different parts of the project while maintaining the overall structure and organization of configuration settings. Go to Example Get Source File The environment file can load results of commands \u00b6 Use the backtick notation \\ command`` to place the results of commands into environment variables: export PHOTO=`base64 image.jpeg` One can load the PHOTO variable in API files. Chain requests through Javascript blocks \u00b6 Lama2 supports plain Javascript (JS) blocks as a glue for manipulating responses and passing on values to later stages. At a higher level, a chain of requests may look like: Javascript 1 --- L2 Request 1 --- Javscript 2 --- L2 Request 2 The triple-dash ( --- ) separator is mandatory. The special variable result contains the response from previous stages. For example, in the above case, Javascript 2 can access the response from L2 Request 1 through the result variable.

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.\\ to \\ 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 . Container , error ) Method Parse normalizes newlines and then creates a rune version of the input data. 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 .
