FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package ecl
ECL
ECL is a simple query language intended for use with data sources that generate tabulated data. It allows you to query data from these sources and do some limited manipulation. It supports conditional statements, loops, variables and comments. There are almost certainly bugs. Pls report!
Syntax
ECL is based on bash's shell syntax. You'll find similar ideas here:
- Comments (
# HACK). - Variables (bools, ints, floats, strings, arrays).
- String concatentation (
"app"'le'). - Output redirection via
>and|. - Control flow (
ifandfor). And some other stuff I'm forgetting.
The authoritative source for syntax questions is the grammar. For a gentler introduction, try checking out the examples below.

Statements
Set
The set statement allows you to assign a primitive value to a variable. Has no return value.
VAR: The name of the variable.
VALUE: The value to set the variable to. Supports bools, ints, floats, strings and arrays.
Example: set num=10
Cond
The if statement allows you to branch execution. It accepts an ECL expression which allows you to access any global variables. Returns the value of the winning branch.
COND: An SEL expression.
BRANCH_A: The truthy branch.
BRANCH_B: The falsey branch.
Example: iftrue{ es:logstash url:"/" } else { es:logstash -url:"/" }
Loop
The loop statement allows you to loop over a result. Each iteration of the loop body sets the _ variable. Returns the value of the loop body.
VAR: The result to iterate over.
CODE: The code block to execute.
Example: for res { count }
CommandList
The CommandList is a pipeline of Commands to execute. Output from each Command flows to the next one until it reaches the end. You can copy the output for almost all Commands into a varible. Returns the output from the final Command iff it is not redirected into a variable.
AAA,BBB,CCC,DDD: Commands
Commands
Count
Returns the result count for the result set.
Filter
Filters the result set with the provided expression.
EXPR: An SEL expression.
Example: filter_['level'] == 'info'``
Head
Returns the first n results.
NUM: The max number of results to return.
Example: head 5
Tail
Returns the last n results.
NUM: The max number of results to return.
Example: tail 5
Join
Performs an inner join on two result sets.
TYPE: The type of join (inner, left, right).
RES: The result set to join with.
FIELD: The field to join on.
Example: join res_a=request_uaid
Map
Map field names and values in the results. You can specify multiple clauses in a single Command and they'll be executed in order.
Example: map count=_ + 3_type=type -_type
Search
Returns data from ES. Supports ES2.x-ES6.x
SRC: The source (usually logstash).
OPTS: Search options.
QUERY: A query.
ATYPE: Aggregation type.
AOPTS: Aggregation options.
Supports most standard ES syntax with a few extras:
Example: es:logstash _type:info_log | agg:terms ip_addr
Sort
Returns the results, sorted.
FIELD: The field name to sort on.
ORD: asc or desc.
Example: sort request_time,asc
Load
Load a result set.
AAA,BBB: Variables.
