Seer console does not interpret ANSI escape codes

[culyun]

I use ANSI escape sequences to colourise terminal output. These are interpreted correctly by pretty much every terminal out there.

The Seer console does not appear to understand these escape sequences.

Please provide the ability to interpret ANSI escape sequences.

Thanks for trying Seer out.

A better console has been on my list for a long time. I've been looking for a light-weight terminal "widget" that can be easily included with Seer's code base without too many dependecies. This one looks promising.

Alternatively, another Seer use suggested an option to output text to the terminal that Seer was launched from. (Not always possible, through) https://github.com/epasveer/seer/issues/225 Not sure if that's enough for you.

Just some references for myself.

Hi Steve,

Just want to confirm its for colorizing text. And not more advance ANSI codes like cursor positioning and screen clearing...

Thanks.

I only use ANSI colour codes, but use your judgment.

I recommend looking for a FOSS VT100 terminal widget for QT. Must be a few around.. I do not recommend writing it yourself :-)

The full set of escape sequences goes back to some Brotosaurus-B mainframe, and is of little value IMO. But I think a reasonable subset would be the goal. Some terminal GUI libraries push this quite hard..

Thanks for the added info.

I might add simple color codes to my simple widget, for now, while I look for a QT terminal widget.

What I'm concerned is making the build process still simple/reliable if I add an external project for the terminal widget...

I've started this side project for a QAnsiTextEdit widget.

Hi @culyun

I've updated Seer with my new QAnsiTextEdit widget.

If you want to try it, clone this branch and build it. Let me know of problems. There will likely be some.

$ git clone -b 240-seer-console-does-not-interpret-ansi-escape-codes https://github.com/epasveer/seer.git

Thanks.

Merged into mainline. Let me know of problems. Closing task. Can be reopened if needed.
