lines multimethod

Methods

lines(s:Str) Source: stdlib.ngs:3443

Split s to strings using end-of-line separators. UNIX and Windows line endings supported (Windows - not tested yet). Warning: Max OS <= 9 line separation of CR (\r) is not supported

Example

"xx\nyy".lines()  # %[xx yy]

lines(s:Str, cb:Fun) Source: stdlib.ngs:3453

Split s to strings using end-of-line separators and call cb for each one of the lines. TODO: More efficient implementation, which would not have temporary array of all lines.

Parameters

cb	Function to be called with each line

lines(f:File, cb:Fun) Source: stdlib.ngs:4353

Iterate over lines of the file

Parameters

f	Closed File
cb	function to call with successive lines from the file

lines(f:File) Source: stdlib.ngs:4368

Get all lines of the file

Returns

Arr of Str

lines(f:File, lines_:Arr) Source: stdlib.ngs:4373

Write given lines to the file. Overwrites the file.

Returns

Arr of Str

lines(p:Process) Source: stdlib.ngs:5046

Wait for the process and return lines of its stdout.

Returns

Arr of Str

Example

$(seq 10 2 20).lines().map(Int)  # [10,12,14,16,18,20]

lines(p:Process, cb:Fun) Source: stdlib.ngs:5054

Iterate lines of Process' stdout, calling cb with successive lines. Warning: current implementation waits for the process to finish, accumulates all its stdout, and only then starts calling cb for each line.

lines(cp:CommandsPipeline) Source: stdlib.ngs:5062

Wait for cp and return lines of stdout of the last process.

Returns

Arr of Str

Example

$(seq 3 | tac).lines().map(Int)  # [3,2,1]

lines(cp:CommandsPipeline, cb:Fun) Source: stdlib.ngs:5070

Wait for cp and return call cb for each line of stdout of last process. Warning: current implementation waits for the processes to finish, accumulates all stdout of the last process, and only then starts calling cb for each line.

Returns

Arr of Str
