vscode: Terminal Shell Integration Error -- bash: eval: line 5: unexpected token `EOF' in conditional command

Type: Bug

With Terminal Shell Integration enabled opening a terminal results in the below error being reported in the shell window:

bash: eval: line 141: unexpected token `EOF' in conditional command
bash: eval: line 141: syntax error: unexpected end of file

A very similar error is reported everytime a command is executed (or the enter key is pressed):

bash: eval: line 5: unexpected token `EOF' in conditional command
bash: eval: line 5: syntax error: unexpected end of file

Enabling set -x and hitting enter in the terminal shows this output:

+++ __vsc_preexec_all -x
+++ '[' 0 = 0 ']'
+++ __vsc_in_command_execution=1
+++ builtin eval '[['
bash: eval: line 5: unexpected token `EOF' in conditional command
bash: eval: line 5: syntax error: unexpected end of file
+++ __vsc_preexec
+++ __vsc_initialized=1
.... TRUNCATED ....

Looking at /usr/share/code/resources/app/out/vs/workbench/contrib/terminal/browser/media/shellIntegration-bash.sh reveals that the command (line 127) causing the error is:

__vsc_dbg_trap="$(trap -p DEBUG | cut -d' ' -f3 | tr -d \')"

which is called by the command (line 140):

builtin eval ${__vsc_dbg_trap}

Running echo ${__vsc_dbg_trap} in the integrated terminal returns (minus the bash eval errors):

[[

When I execute the trap -p DEBUG command (from line 127) in another bash shell (outside of VSCode) the result is:

trap -- '[[ "$BASH_COMMAND" != "$PROMPT_COMMAND" ]] && chruby_auto' DEBUG

and running the full trap -p DEBUG | cut -d' ' -f3 | tr -d \' command (from line 127) returns:

[[

This did not occur prior to version 1.70.0 even with the Shell Integration setting enabled.

@jazzlw I think you are hitting what was reported in #157851 and fixed in #158124

++++ ‘[[ “$BASH_COMMAND” != “$PROMPT_COMMAND” ]] && chruby_auto’

That is the line that is trying to be run and it has the ' around it so bash thinks it is a single string and doesn’t parse it. Which results in the error:

bash: [[ “$BASH_COMMAND” != “$PROMPT_COMMAND” ]] && chruby_auto: command not found

trap – ‘[[ “$BASH_COMMAND” != “$PROMPT_COMMAND” ]] && chruby_auto’ DEBUG

That trap command is coming from chruby which is used for managing different Ruby versions. The code adding it can be found at https://github.com/postmodern/chruby/blob/613a4834049e4d8de52de764213182a59c214ce1/share/chruby/auto.sh#L32.

I had this same issue, and just updated. The original issue is gone, but now I get another bash error: bash: [[ "$BASH_COMMAND" != "$PROMPT_COMMAND" ]] && chruby_auto: command not found

Using set -x to see what’s running yields:

+++ __vsc_preexec_all clear
+++ '[' 0 = 0 ']'
+++ __vsc_in_command_execution=1
+++ builtin eval ''\''[[' '"$BASH_COMMAND"' '!=' '"$PROMPT_COMMAND"' ']]' '&&' 'chruby_auto'\'''

@meganrogge should I make a new issue for this?
