Usage

Parmeters for zsh-toggle()

  • arg1: EXPORT
    • [true|false]
    • Whether the variable has an export statement or not. Default is 'false'
  • arg2: DQUOTES
    • [true|false|none]
    • Whether the variable has double quotes, single quotes or none. Default is 'true'
  • arg3: VAR_NAME
    • [string]
    • The name of the variable
  • arg4: VALUE
    • [string]
    • The current value of the variable
  • arg5: ALT_VALUE
    • [string]
    • The alternte value for the variable
  • arg6: FILE_PATH
    • [string]
    • The fully qualified path to the file containing the variable

In the file that contains the variable(s) that you want to toggle. The variable should ...

  • be on a line of its own.
  • be only one of the following formats:
    • $MY_VAR="true" no export statement, double quotes
    • $MY_VAR='true' no export statement, single quotes.
    • $MY_VAR=true no export statement, no quotes.
    • export $MY_VAR="true" export statement, double quotes
    • export $MY_VAR='false' export statement, single quotes.
    • export $MY_VAR=false export statement, no quotes.
  • be initialized with a value such as true|false, on|off, 1|0, yes|no John|Amy etc.
  • It can be any two values that you want to toggle between.

The variable you are toggling should be initialized in its file already with either VALUE or ALT_VALUE otherwise it won't work. For example if you set

VALUE="yes"
ALT_VALUE="no"

then in the file @ FILE_PATH the variable should be initialized with either "yes" or "no". ex. MY_VAR="yes" or MY_VAR="no" The same with the other options too. If you set DQUOTES or EXPORT to "true" then the variable value should be wrapped in double quotes and/or be exported already in the file. Your basically describing the variable with these options

Another example:

If you call zsh-toggle like this

zsh-toggle false true TEST "false" "true" "$(pwd)/test.conf"

then the variable in the file your pointing at with the last argument should look like this:

TEST="false"
# or
TEST="true"

If you call zsh-toggle like this

zsh-toggle true false TEST "on" "off" "$(pwd)/test.conf"

then the variable in the file your pointing at with the last argument should look like this:

export TEST='on'
# or
export TEST='off'

You can also call zsh-toggle passing "none" for the 2nd argument to use no quotes like this:

zsh-toggle false none TEST "false" "true" "$(pwd)/test.conf"

In this case the variable in the file your pointing at with the last argument should look like this:

TEST=false
# or
TEST=true
