In isUnsupportedTerm I suggest changing it to:

if (term == NULL) return true;

This is mainly because CLion's integrated console does not set TERM and does not work with line noise or cpp-linenoise. Instead of getting the prompt we the following noise, plus the enter key is not picked up - so readline never exits;

By making this small change, the CLion console works:

Is there any way to differentiate between whether user entered blank line or Ctrl+C. I currently don't see way in Realine() API. I think it would be nice to have a call back for Ctrl+C, Ctrl+Z etc.

Hi,

I have following problem.
After I stop linenoise stdin is closed or something like this.
See https://github.com/cppan/cppan/blob/master/src/client/init.cpp#L130-L134
When while() loop is stopped, I need to read from stdin again, but I can't. (Tried this on linux/win32.)
Program can react only on ctrl+c.

Linenoise register at_exit callback to restore standard streams behavior. But I need to restore it immediately after while loop.
Probably it could be done by adding separate function for this.

Briefly:

while (!linenoise::Readline(...)) { ... }
cin >> myvar; // does not work!!

We need:

while (!linenoise::Readline(...)) { ... }
linenoise::RestoreStdinBehavior(...);
cin >> myvar; // works!!

I'm compiling everything with all warnings as errors (it's just good practice). On GCC linenoise has one warning and doesn't compile:

.../include/linenoise.hpp:1826:12: warning: unused variable ‘plen’ [-Wunused-variable]
     size_t plen = l->prompt.length();

I am getting errors like this when include libnoise.hpp in multiple source (cpp) files in my project (https://github.com/machinezone/IXWebSocket)

Example file -> https://github.com/machinezone/IXWebSocket/blob/ac9710d5d6e1c3dba1c681168cca39e358ab73ef/ws/ws_redis_cli.cpp

The way I solved it is by moving the body in an implementation file, but I wonder if there's a better way.

(fix => machinezone/IXWebSocket@6ed8723)

I think this is a great project but personally the use of C++ is a deal-breaker for me.

What is the dependency of cpp-linenoise on C++ ? Have you considered switching to C ?

Compiling with VS2015 gives me this error:
Severity Code Description Project File Error C2664 'int linenoise::win32read(int *)': cannot convert argument 1 from 'int **' to 'int *'

Changing line 1802 from
nread = win32read(&c);
to
nread = win32read(c);
solves the issue for me.

I'm not familiar with your code, so not sure if this makes sense.

For now, there is no way for an autocomplete handler to understand where the user cursor is exactly located. It would be nice to have one, as in many cases the user wants to autocomplete something in the middle of the input string.

cpp-linenoise.hpp builds and runs on C++11 compilers, but -Wall produces many warnings - implicit signed/unsigned conversions, old style casts, deprecated functions (sscanf), goto crossing a variable initialization. The goto issue is actually considered fatal in gcc unless -fpermissive is specified.

Any thoughts about updating the source?

Building on a MS compiler gives many warnings related to conversions between size_t and int, and similar. On a build that forces warnings to be errors, this was a problem. I had to patch the source code to do the casts.

Hiya,

When writing to the terminal on one thread, and reading on another with linenoise, output will be strangely indented.

The problem and patch is perfectly summed up in this thread - antirez/linenoise#128 - I wondered if you would be interested in applying the patch.

Thanks for the library by the way, it's far nicer to use than the C linenoise ❤️

Just saw this bug...

Repro steps:

1. Setup linenoise with few autocomplete.
2. Press first char, press Tab to do auto complete.
3. Press space.

Notice that tab gets appended in console. if you try to do backspace, you get weird behavior now.

Hi there,

I am currently porting this library to hunter (a cmake based package manger) and encountered build errors using mingw and msys.

Build logs can be found here:

• mingw
• msys

Whenever the input contains non-ASCII characters that consist of multibyte characters, then the cursor position is wrong.
For example, when entering ö (an Umlaut character), the cursor will go to the right by 2 positions, but it should advance only one character. The reason for this is that the ö consists of two bytes in UTF-8, and entering this characters causes two calls to read() insidie linenoiseEdit() and the linenoise version used does not seem to be Unicode-aware at all.
So for UTF-8 multibyte characters it is broken, at least on all the Linuxes I tried.
