Detailed Description

The Err struct contains the attributes of a parsing error from i3wm when trying to run an unparsable command;.

This is the processed reply for a qi3pc::IpcType::Command reply.

QStringMemberPtr

using qi3pc::ParseError::QStringMemberPtr = QString ParseError::*

QString member pointer of ParseError.

Member Function Documentation

toString()

QString qi3pc::ParseError::toString

(

)

const

Convert to a json like string.

Returns

QString representation of the ParseError

The resulting string is in the form "{member:'member'}{member2:'member2'}".

Note

This is NOT valid JSON. Notice the lack of commas between elements.

operator==()

bool qi3pc::ParseError::operator==

(

const ParseError &

other

)

const

Memberwise comparison of this ParseError and another.

Parameters

other

The second object to compare.

Returns

whether all members are equal

Definition at line 753 of file qi3pc.cpp.

References error, errorPosition, and input.

FromJSON()

qi3pc::Error qi3pc::ParseError::FromJSON ( const QJsonObject & json )

static

Build an optional ParseError from a QJsonObject.

Parameters

json	JSON object with structure matching ParseError::_MEMBERS.

Returns

A ParseError or a nullopt.

At least "parse_error" should be in the JSON. If it's not present, a nullopt is returned. If only that key and none of the other checked ones exist, a default initialized ParseError is returned. Otherwise for each of the checked keys found, the corresponding member is initialized. Values in the JSON are expected to be of string type.

Member Data Documentation

error

QString qi3pc::ParseError::error

Human readble error message.

Definition at line 172 of file qi3pc.h.

input

QString qi3pc::ParseError::input

The command that failed to run.

Definition at line 175 of file qi3pc.h.

errorPosition

QString qi3pc::ParseError::errorPosition

The position where the error was detected in the input.

This is a string of the same length as the input. Spaces ' ' represent the parsable part of the input. Starting from where the error was detected, the rest is represented with carets '^'.

Definition at line 185 of file qi3pc.h.

_MEMBERS

auto qi3pc::ParseError::_MEMBERS

inlinestaticconstexprprivate

Initial value:

= std::to_array<std::pair<const char*, QStringMemberPtr>>
    ({
       {"error", &ParseError::error},
       {"input", &ParseError::input},
       {"errorposition", &ParseError::errorPosition}
     })

Mapping of i3wm's parse error reply's attributes to members of ParseError.
