I've made a fully POSIX Shell compliant fork you can take a look at here. While I have no intention of opening a pull request, I do have some interesting features like better ASCII detection, and a bit of a hack that replaces the sleep with a blocking read timeout, but ends up being a very elegant solution to sneak fully functioning user input into the current codebase. Feel free to take a look.

What steps will reproduce the problem?
1. mettre append_tabbed `cat /proc/meminfo | awk '/MemTotal/ {print
"Total:" $2/1024}'` 2 => Ca marche
2. `cat /proc/meminfo | awk '/MemTotal/ {print "Total:" $2/1024}'`
=> Erreur ./simple_curses.sh: line 202: LASTCOLS/: erreur de syntaxe :
opérande attendue (error token is "/")

What is the expected output? What do you see instead?
Ça aurait facilité le debuggage de voir "erreur pas de second argument à
append_tabbed"

Working on a PR (#65) for this cool project, but wanted to ask about something before charging in with this particular part.

There are quite a few instances of 'if true that something is not equal to nothing', which is unnecessarily taxing to mentally parse. This is why we have the -z and -n flags for when something is and is not empty, respectively. You've used this already, but — and this is largely why consistency is important — you've often not, which is confusing. Is there a bizarre nuanced use-case I'm missing?

Incidentally, is there a reason you've used a lot of [ instead of [[, yet also used [[? I can only imagine how much this will have confused people reading my old code, because I did the same thing, and I'm now confused reading someone else's for the same reason! Lol In a nut-shell, I found out (through quite a bit of testing) that [[ is far more efficient than [. I had to change all my code to correct this, which sucked.

Hey everyone,

I'm trying to use this lib, btw is AWESOME, but I have no idea how I can read from the keyboard when I'm showing the information to the user.

e.g: If the user types the key r change the colors to red.

When running
make test
it comes out really bad looking on Debian 8:

-e Warning - You should install caca-utils or img2txt command

strace(1) shows that /bin/sh is used.
man sh gives the manual page for dash, and that manual page shows that the builtin echo does not support -e as an option.
Setting SHELL=bash as the first line in Makefile makes the output look at expected on Debian 8.

I'm not sure if some creates other problems or if some systems require a full pathname to bash.

I feel silly, but I can't figure out how to change the border colour?

The documentation is really poor and full of English mistakes.

I have tried some emulation terminals such as xshell and putty with same result.

I used the last version of bashsimplecurses.

test.sh

#!/bin/bash

#import library, please check path
#source /usr/lib/simple_curses.sh
source simple_curses.sh

#Then, you must create a "main" function:
main () {
#your code here, you can add some windows, text...
window "title" "red" "50%"
append "Text..."
endwin
}

#then, you can execute loop:
main_loop 1

Hello, I'm trying to create a TUI for my app, yeast. But for this, I need to get user input in the window. Can someone provide me with some help?

Thanks in advance,

Hi,

Firstly, thank you for creating this package, it works like a dream. I have detected a small issue when the simple_curses.sh script tries to determine if UTF-8 is set. The issue maybe related to the version of bash. My LANG is set to en_GB.UTF-8.

$ bash --version
GNU bash, version 4.3.42(1)-release (x86_64-pc-linux-gnu)

To solve this issue I had to remove the " " marks around the regex on line 91:

 -    if [[ -z "$ASCIIMODE" && $LANG =~ ".*\.UTF-8" ]] ; then ASCIIMODE=utf8; fi
 +    if [[ -z "$ASCIIMODE" && $LANG =~ .*\.UTF-8 ]] ; then ASCIIMODE=utf8; fi

Hopes this helps someone !

Many thanks
Martin

I'm seeing that there are occasions when loading if there's an error with the code that would display that instead of presenting an error I am redirected back to the command prompt.

Is it possible to align text to the right like in the screenshot?

What steps will reproduce the problem?
1. run any sample on ubuntu 9.04 ( and other ubuntu and ubuntu-like ? )
( fine on fedora mktemp/coreutils-7-2-1.fc11  )

What is the expected output?
The expected output :)

What do you see instead?
An unexpected output :)
mktemp: invalid option -- '-'
Usage: mktemp [-V] | [-dqtu] [-p prefix] [template]
./simple_curses.sh: line 51: $BUFFER: ambiguous redirect
./simple_curses.sh: line 270: $BUFFER: ambiguous redirect
./simple_curses.sh: line 271: $BUFFER: ambiguous redirect
./simple_curses.sh: line 272: $BUFFER: ambiguous redirect
./simple_curses.sh: line 273: $BUFFER: ambiguous redirect

( $BUFFER empty )

What version of the product are you using? On what operating system?
bashsimplecurses-0.0.1
ubuntu 9.04 (x86_64) and mktemp 1.5-9

Please provide any additional information below.
Just change line 23 of simple_curses.sh
Before :
mktemp --tmpdir=${BUFFER_DIR} ${buffername}.XXXXXXXXXX
After :
mktemp -p ${BUFFER_DIR} ${buffername}.XXXXXXXXXX

2 files or just an uggly test on top of simple_curses.sh to choose
alternate syntax of mktemp ? 
mktemp --tmpdir=${BUFFER_DIR} ${buffername}.XXXXXXXXXX > /dev/null 2>&1 &&
MKTEMP="mktemp --tmpdir=" || MKTEMP="mktemp -p "
And line 23 :
${MKTEMP}${BUFFER_DIR} ${buffername}.XXXXXXXXXX || { echo "mktemp syntax
error" ; exit ; }
Alternately OS detection should be better ? But kernel dependant...
uname -v | grep -q "Ubuntu" && MKTEMP="mktemp -p" || MKTEMP="mktemp -tmpdir="
Hhhmmm... That's a packaging policy problem !

And thanks for the embeded tty :)

I feel that output needs some TLC. It's exhaustive for usage output. The formatting could do with a tidy. I would suggest looking into writing a man page, at this point, because there seems to be a lot of information to offer. What do you think?

I absolutely recommend a usage format like:

Usage: program [OPTS]

  -h, --help               - ...
  -v, --version            - ...
  ...                      - ...
  ...                      - ...

Some brief information here, if needed.

I might be biased, because I use it in all of my programs, but it's because it's so dang discreet and easy to read! Just as you'd expect from an overview of usage, where the man page ideally goes into more detail. I also ensure the line never exceeds <= 80 columns so that the information is readable; keeping things concise helps.

If you're curious and want to see some examples of what I have in mind, check out some of my projects in both Extra and PerlProjects, like Cito, GLKFU, AutoExec, LSBLK, CSi3, DTP, UbuChk, etc.

First, let me say, this is Awesome - Thank you!

I was wondering if it would be possible to have an option to NOT use xterm, not loop, and just simply run each script once and display the output (while still keeping your incredible output format).

I'm having issues running remotely:
tput: No value for $TERM and no -T specified
and simplifying the environment should solve that, if it's feasible.

Thanks again.

I tried running the examples on my Mac with zsh terminal and it aborts immediately. Then I upgraded ncurses as per one of the other issues suggestions but that didn't change the behavior. Also when run from iTerm2 against a EC2 host, it has a terrible blinking issue with the last cursor line flashing. Seems like a useful tool if I could make it work. Consider including documentation on what OS/dependencies are required.

What steps will reproduce the problem?
1. Try compiling and testing on RHEL5/CentOS5 (in my case 5.6)
2.
3.

What is the expected output? What do you see instead?

i expected to see a windows in terminal, instead i see a blank window with 
occasional error ocasionalmessage about improper usage of "mktemp" command in 
create_buffer function. 

What version of the product are you using? On what operating system?
0.1 alpha

Please provide any additional information below.

For the case of RHEL5/CentOS5 and possibly fedora in RHEL based distro's in 
general, mktemp "--tmpdir" is not a valid argument. Instead, please use option 
"-p". Once replaced all seemed to work. 

Suggestion: please add a funtion that determines the mktemp version or distro 
and uses appropriate switch..

Thanks
-ilya

if you look at the first line, the code for readme.md is

#headerone

it should be

# headerone

This is a new thing with GFM I think.

What steps will reproduce the problem?
1. create a toto.sh file, cut/past the 2 first windows of the sample on the
homepage
2. run

What is the expected output? What do you see instead?
I expect to see the two windows titled "Hostname" and "Memory Usage"
instead I see the two windows (as expected) AND a line with the hostname
at the bottom of the bash window (see attached picture)

What version of the product are you using? On what operating system?
latest from trunk (there is nothing in the downloads section)

Sorry to make an Issue about this — I've nowhere else to really post it.

What's this project's stance on rebasing? I've used Git and GitHub for years, but I've never really rebased in Git before, until now. I'm actually really happy I discovered how to do it, but from looking online, it seems it can be very destructive if not done properly. That's why I'm posting here, to double-check.

I made 3 commits to my local fork of BSC, in preparation for another PR. These changes have not been pushed. I realised I missed something from the 1st commit, so I rebased back to the first commit, made the changes, then amended those changes to the commit. There were no conflicts and everything seemed to work successfully.

My concern is mainly that it'll somehow cause issues for y'all, since I don't yet properly understand rebasing. It strikes me that it'd be fine, because they were local changes and I didn't rebase to or before someone else's changes, but I'm not certain.

I'd rather be annoying and ask, than be quiet and make a mess. 😄

In order of events:

1. Made changes. Made a commit.
2. Made changes. Made a 2nd commit.
3. Made changes. Made a 3rd commit.
4. Realised I missed something in 1.
5. Rebased to 1: git rebase -i SHA^
6. In Vim, edited 'pick' to 'edit' for SHA.
7. Made changes, then amended to commit: git commit --amend
8. Continued the rebase: git rebase --continue

Maybe that'll help, in-case I didn't explain clearly.

I've looked online and git-rebase(1), but I either can't find anything concrete, or I frankly just don't understand.

What steps will reproduce the problem?
1. Mettre append "`cal -m`"
2. Observer: on a tout sur une ligne

What is the expected output? What do you see instead?

Here is a little patch to use mktemp if possible, and to revert to a 
standard file buffer if SHM is unavailable.

Also, there was a small spelling error on "license".

I tried running some of the examples, but instead of colors I get ansi escape codes... Any hints how to make it work? I tried with both the terminal app and iterm on macOS.

file wintest.sh line 12 (svn):
append_command "tree -L 2 -C -A ./"

A demo is nicer when we don't need anythig else ;)

I have a simple program I'm building that shows windows, one displays the contents of a file (JSON), and the other displaying the results of a transformation of that JSON (a JQ command). I need an input box somewhere on the screen so the user can dynamically edit the JQ query. I don't see anything in the code that handles input, and my naive approaches with read caused big problems with the windows.

Any suggestions on how to approach this? I'd be happy to create a PR if I knew what was needed to make this possible.

I have added a new section in init_char() function to allow utf-8 encoding. It 
is based con unicode fonts at:

im not a big bash scripter, i barely know anything, yet id still like to know how to actually do anything with the choice you can pick in the choices example. ive changed it a little like you see here now:

#i ran: (commandname) list add remove

source /usr/local/lib/simple_curses.sh

declare -a SELECTABLES
while [[ $# -gt 0 ]]; do
  # shellcheck disable=SC2034
  case "$1" in
  -- ) shift; break ;;
  * ) SELECTABLES+=("$1"); shift ;;
  esac
done
# SELECTABLES=( "$@" )
arraylen=${#SELECTABLES[@]}
selected=0
lastselected=$selected


main(){
    window "Would you like to list/add/remove services?" "red" "50%"

    local count
    count=0
    for i in ${SELECTABLES[@]};do
        bgcolor="black"
        color="blue"
        [ "$selected" == "$count" ] && {
            bgcolor="blue"
            color="red"
        }
        append "$i" $color $bgcolor
        count=$(( count + 1 ))
    done
    endwin
    lastselected=$selected
}
update(){
    local ret
    local success

    read -r -n 1 -s -t 1 ret
    success=$?

    if [ "$success" -lt 128 ]; then
        if [ "$ret" == $'\e' ];then
            read -sN2 -r k1
            success=$?
            ret+=${k1}
        fi

        case $ret in
            [0-9])
                selected=$(( $ret - 1 ))
            ;;
            $'\e[A'|$'\e[D')
                selected=$(( selected - 1 ))
                [ "$selected" -lt "0" ] && selected=$(( arraylen - 1))
            ;;
            $'\e[B'|$'\e[C')
                selected=$(( selected + 1 ))
                [ "$selected" == "$arraylen" ] && selected="0"
            ;;
            $'\e')
                return 255
            ;;
            *)
                return $(( $lastselected + 1 ))
            ;;
        esac
    fi

    return 0
}

main_loop "$@"

i dont understand the update function but i can figure the rest, i just want to know how i can, for example, make a new menu popup when i pick one of the choices?

What steps will reproduce the problem?
1. Wiki => basicTutorial

Users should not need to go to the documentation (readthedoc) page to understand and have examples - so, we need a better README file.

Hi,

While running simple_curse.sh in RHEL 7 & RHEL 8. I found a issue that "bsc_cols=$(tput cols)" variable is getting set as 80 in RHEL 7 while actual "$(tput cols) value is 183" see below example. In RHEL8 I didn't find this issue as "echo $(tput cols) is 182 & bsc_cols=182" as well

Hi,

Can you create a progress bar ( to copy a file or monitoring memory for
example ) ?

Best regard

Intro

Hi there! I'm really pleased with bashsimplecurses - thank you!! I've just launched a tool that uses it and we're seeing that MacOS users do not get a full width window when running a script that declares window "100% wide window" "red" "100%" Instead an 80 char wide window is shown. Since our script displays information that some times is wider than 80 chars, it'd be great if bashsimplecurses supported full width on MacOS.

Steps to reproduce

1. Be on MacOS - tested on 10.13.6 and 11.x & in ohmyzsh, bash and sh
2. Clone this repo (as of 054a04a)
3. cd into ./bashsimplecurses/examples
4. Create a file called macos.sh with this contents:

   #!/bin/bash
   . `dirname $0`/../simple_curses.sh
   main (){
       window "100% wide window" "red" "100%"
       append "`date`"
       endwin
   }
   main_loop -t 0.5 "$@"

5. Run chmod +x macos.sh&& ./macos.sh

Expected: Window is shown full width of current terminal
Actual: Window is always shown at 80 chars wide, no bigger, no smaller

Related - setting it to 50% in the script seems to show it at 40 chars wide ( i guess half of the 80 chars it thinks the terminal always is)

Screenshots

Here's a local shell on Ubuntu 20.04/ohmyzsh on the top and and SSH shell on macos/ohmyzsh on the bottom. The first shows a screen ~107 chars wide, the second shows one ~40 chars wide:

Here's the same script running on in a local shell on MacOS:

Hello guys,

here is a little demonstration of what can be done: https://twitter.com/Notfound404__/status/1205977338439241730?s=20

Bash for fun and profit.

If I clone this repo, and create a file e.g. sample.sh in the same folder, and add a content almost identical to the README sample on it:

#!/bin/bash
source ./simple_curses.sh

main (){
    #your code here, you can add some windows, text...
    window "title" "color"
    append "Text..."
    endwin
}

main_loop 1

Then adding execution permission (chmod +x simple_curses.sh) and executing it I got this:

$ ./sample.sh 
Option 1 does not exist

Removing the 1 argument to the main_loop call in the last line of the script solves the issue.

Is the example in the README wrong/outdated ?

Hey!
I just wanted to be able to exit with a terminal with a 'good' aspect.
What do you think to make the onkill function like this?
on_kill(){
    tput cup 0 0 >> $BUFFER
    # Erase in-buffer
    tput ed >> $BUFFER
    cat $BUFFER
    rm -rf $BUFFER
    exit 0
}
Cheers.
.Yves.

Hi,

I'm building a status script where I'd like lines of text displayed using the same way the latest kernel messages are printed in bashbar.sh but in a column. For some reason text spills below the left windows.

Below is my modified bashbar.sh (basically added 50% to all windows)

#!/bin/bash

. `dirname $0`/simple_curses.sh

main (){
    #basic informations, hostname, date,...
    window "`hostname`" "red" "50%"
    append "`date`"
    addsep
    append_tabbed "Up since|`uptime | cut -f1 -d"," | sed 's/^ *//' | cut -f3- -d" "`" 2 "|"
    append_tabbed "Users:`uptime | cut -f2 -d"," | sed 's/^ *//'| cut -f1 -d" "`" 2
    append_tabbed "`awk '{print "Load average:" $1 " " $2 " " $3}' < /proc/loadavg`" 2
    endwin

    #memory usage
    window "Memory usage" "red" "50%"
    append_tabbed `cat /proc/meminfo | awk '/MemTotal/ {print "Total:" $2/1024}'` 2
    append_tabbed `cat /proc/meminfo | awk '/MemFree/ {print "Used:" $2/1024}'` 2
    endwin

        col_right
        move_up

    #5 more used process ordered by cpu and memory usage
    window "Processus taking memory and CPU" "green" "50%"
    for i in `seq 2 6`; do
        append_tabbed "`ps ax -o pid,rss,pcpu,ucmd --sort=-cpu,-rss | sed -n "$i,$i p" | awk '{printf "%s: %smo:  %s%%" , $4, $2/1024, $3 }'`" 3
    done
    endwin

    #get dmesg, log it then send to deskbar
    window "Last kernel messages" "blue" "50%"
    dmesg | tail -n 10 > /dev/shm/deskbar.dmesg
    append_file /dev/shm/deskbar.dmesg
    rm -f /dev/shm/deskbar.dmesg
    endwin

    #a special manipulation to get net interfaces  and IP
    window "Inet interfaces" "grey" "50%"
    _ifaces=$(for inet in `ifconfig | cut -f1 -d " " | sed -n "/./ p"`; do ifconfig $inet | awk 'BEGIN{printf "%s", "'"$inet"'"} /adr:/ {printf ":%s\n", $2}'|sed 's/adr://'; done)
    for ifac in $_ifaces; do
        append_tabbed  "$ifac" 2
    done
    endwin
}
main_loop 0.5

Am I doing something wrong?

Cheers and thanks!
