debug with chrome and extensions

react developer tools doesn't load until open in global scope browser as result the extension not visible when debugging, to workaround this edit launch.json as follow ( you may need to edit your tool extension path in runtimeArgs

{   
    "version": "0.2.0",
    "configurations": [                
        {
            "type": "chrome",
            "request": "launch",
            "name": "Launch Chrome against localhost",
            "url": "http://localhost:3000",
            "webRoot": "${workspaceFolder}"    ,
            "runtimeArgs": ["--load-extension=${env:HOME}/.config/google-chrome/Default/Extensions/fmkadmapgofadopljbjfkapdkoienihi/4.2.0_0/"]
        }
    ]
}

another crude hack is the following editing directly /opt/google/chome toward end of file ( it enabled extension for user devel0 when remote-debugging-port argument used such as from configuration types chrome or coreclr with ServerReadyAction / debugWithChrome

# Note: exec -a below is a bashism.
if [ "$USER" == "devel0" ]; then
#       echo "$@" > /tmp/log1
        if [ "$(echo $@ | grep remote-debugging-port)" != "" ]; then                
                extpath=$HOME/.config/google-chrome/Default/Extensions/fmkadmapgofadopljbjfkapdkoienihi
                v=$(ls $extpath)
                exec -a "$0" "$HERE/chrome" \
                        --load-extension=$extpath/$v/ \
                        "$@"
        else
                exec -a "$0" "$HERE/chrome" "$@"
        fi
else
        exec -a "$0" "$HERE/chrome" "$@"
fi

watch string unescaped

To copy watched string variable with unescaped characters ( for example if contains newlines default Copy value retrieve a string with \n\r instead of unescaped newline ) append ,nq ( no quote ) modifier to the watched variable name ( eg. obj.Message,nq )

develop and debugging with root privileges

code suggest to run as user mode; of course if you need to develop some tool around some other that need privileges you can invoke these through sudo; to avoid terminal interaction in inserting password for sudo privileges for some specific commands edit sudo table by adding an auxiliary file into /etc/sudoers.d for example /etc/sudoers.d/devel0 with follow content:

devel0 ALL = NOPASSWD: /bin/btrfs

this will allow devel0 to exec btrfs tool without password ask when invoked through sudo

set git copy remote url

this will allow you to use right click -> copy remote url feature that copy to clipboard permalink to code selection

in settings.json

{
    "gitlens.remotes": [
        {
            "domain": "git.searchathing.com",
            "type": "GitLab"
        }
    ]
}

add languageid override

to allow XmlComplete recognize axaml as xml add follow to settings.json

    "files.associations": {
        "*.axaml": "xml"
    },

snippets

snippets is located in ~/.config/Code/User/snippets/csharp.json and automatically managed by easy snippet extension

  • basic snippets to place in the above location as csharp.json
  • example for a snippet ( avalonia property ) using underscore prefix for private field
private ${1:int} _${2:varname} = ${3:0};
public $1 $2
{
    get => _$2;
    set => this.RaiseAndSetIfChanged(ref _$2, value);
}
  • example for a snippet ( avalonia property ) using lowercase for private field and uppercase for public prop
private ${1:int} ${2:varname} = ${3:0};
public $1 ${2/(.)/${1:/upcase}/}
{
    get => $2;
    set => this.RaiseAndSetIfChanged(ref $2, value);
}

just recall the snippet with the name assigned from easy snippet then enter var name ( first letter lowercase ) then the public prop will uppercased automatically when hit tab.
