Changes

4.1.0

Many new features and improvements in this version:

  • New keybindings (working on Emacs, and in Vim Insert Mode):

    • CtrlW to cut the previous word at the cursor
    • CtrlA to go back to the beginning of the line
    • CtrlY to paste the laste copy/paste buffer (see Registers)
    • CtrlU to cut the whole line.

  • More precise Vim iterations:

    • Iterations can now be applied to some Vim actions (y4w, d3b)

  • Implemented Vim registers:

    • Yank/paste operations of any sort can occur and be assigned to registers.
    • The default "" register
    • 10 numbered registers, to which bufffers are automatically added
    • 26 lettered registers (lowercase), to which you can append with "D (D being the uppercase of the "d register)
    • Triggered in Insert Mode with Alt" (buggy sometimes: goes back to Normal mode selecting a register, will have to fix this)

  • Unified iterations and registers:

    • To copy to the d register the next 4 words: "d y4w
    • To append to this d register the cuttend end of line: "D d$"
    • In this example, the d register buffer is also the buffer in the default register ""
    • You could either:
      • Paste 3 times this buffer while in Normal mode: 3p
      • Paste the buffer once in Insert mode: CtrlY

  • History completions:

    • The binding for the alternative history changed to AltR (the normal remains CtrlR)
    • By defaul the history filters only against the search pattern.
    • If there are matches for this patten, the first occurence is insert (virtually)
    • This is refreshed as the pattern changes
    • CtrlG to exit the comps, while leaving the current candidate
    • CtrlC to exit and delete the current candidate

  • Completions:

    • When a candidate is inserted virtually, CtrlC to abort both completions and the candidate
    • Implemented global printing size: If the overall number of completions is biffer, will roll over them.

Notes: * The rl.Readline() function dispatch has some big cases, maybe a bit of refactoring would be nice * The way the buffer storing bytes from key strokes sometimes gives weird results (like Alt" for showing Vim registers) * Some defer/cancel calls related to DelayedTabContext that should have been merged from lmorg/readline are still missing.

4.0.0-beta

This version is the merge of maxlandon/readline and lmorg/readline. Therefore it both integrates parts from both libraries, but also adds a few features, with some API breaking changes (ex: completions), thus the new 4.0.0 version. Remains a beta because maxlandon/readline code has not been thoroughly test neither in nor of itself, and no more against lmorg/murex, it's main consumer until now.

Code

  • Enhance delete/copy buffer in Vim mode
  • DelayedTabContext now works with completion groups

Packages

  • Added a completers package, with a default tab/hint/syntax completer working with the go-flags library.
  • The examples package has been enhanced with a more complete -base- application code. See the wiki

Documentation

  • Merged relevant parts of both READMEs
  • Use documentation from maxlandon/readline

New features / bindings

  • CtrlL now clears the screen and reprints the prompt
  • Added evilsocket's tui colors/effects, for ease of use & integration with shell. Has not yet replaced the current seqColor variables everywhere though

Changes I'm not sure of

  • is the function leftMost() in cursor.go useful ?
  • is the function getCursorPos() in cursor.go useful ?

3.0.0

  • Added test (input line, prompt, correct refresh, etc)
  • Added multiline support
  • Added DelayedTabContext and DelayedSyntaxWorker

2.1.0

Error returns from readline have been created as error a variable, which is more idiomatic to Go than the err constants that existed previously. Currently both are still available to use however I will be deprecating the the constants in a latter release.

Deprecated constants:

const (
	// ErrCtrlC is returned when ctrl+c is pressed
	ErrCtrlC = "Ctrl+C"

	// ErrEOF is returned when ctrl+d is pressed
	ErrEOF = "EOF"
)

New error variables:

var (
	// CtrlC is returned when ctrl+c is pressed
	CtrlC = errors.New("Ctrl+C")

	// EOF is returned when ctrl+d is pressed
	// (this is actually the same value as io.EOF)
	EOF = errors.New("EOF")
)

Version Information

readline's version numbers are based on Semantic Versioning. More details can be found in the README.md.
