support for ANSI colors #14

yonizaf commented 5 years ago

I'm using ANSI colors (ANSI escape codes) rather heavily in my scripts. Running them in nppexec console results in a lot of unreadable gibberish.

I it's possible to support colors it would be great. If not, at least filter out the codes, maybe?

d0vgan commented 5 years ago

I'll consider it. ( In fact, I hate when people say "I'll consider it" - because you never know what they actually mean by that: will they just think about it or will they implement it at some point of time :) ). I think the next version of NppExec will be able to filter the color codes. To do that, however, minimal logic of parsing the colors must be implemented anyway - I mean, at least for detection of the beginning and ending of the color code fragment of the output text.

I have to say I am far from being familiar with ANSI colors, and the (ANSI escape codes) does not look clear to me. Is there any sort of "formula" that describes all the possible ESC-sequences? By this "formula" I mean something like the following:

2-byte seqences in form of 0x1B {x}, where {x} is in the range of [{start}, {end}] (question: what are the values of {start} and {end}?)
3-byte seqences in form of 0x1B {x1} {x2}, where {x1} is in the range of [{start}, {end}] (question: what are the values of {start} and {end}?)
n-byte sequences in a form of 0x1B {start} {any number of bytes here} {end} (question: what are the possible values of {start} and {end}?)
n-byte sequences in a form of 0x1B {start_n} {exactly n bytes here} (question: what are the possible values of {start_n}?)
any other possible combination I did not think of

I mean, I need to completely understand where any possible ESC-sequence begins and where exactly it ends - and only basing on this information I'll be able to do any processing, even simple filtering of the ESC-sequences.

Added ability to remove ANSI escape sequences in https://github.com/d0vgan/nppexec/tree/develop . Please check the latest binaries under https://sourceforge.net/projects/npp-plugins/files/NppExec/NppExec%20Plugin%20v0.6%20RC3-RC4%20%28dev%29/

Included in NppExec v0.6.1: the ability to remove ANSI escape sequences (npe_console e1).

If one day NppExec will be able to colourize even parts of its lines (maybe compatibility with ANSI colours?), it would be very nice.
