* Implement basic Lua output support Ref #1700 Basic but working serialization to Lua tables. * Escape larger set of characters in Lua output Started with a minimum of replacements, this should be more complete, tho not all substitutions are strictly required in Lua. * Print simple keys unquoted in Lua output String keys that satisfy the requirements for variable names can be used as keys without quotes in tables. * Quote Lua keywords in table keys Keywords are not valid as unquoted keys, thus must be quoted * Make output of unquoted Lua table keys optional Generally safer and simpler to not do it. * Hook up settings for Lua output * Allow special characters in Lua prefix and suffix --lua-suffix='});^M' didn't work, so taking this approach instead * Panic on unhandled YAML Kind in Lua encoder * Handle YAML case varied booleans in Lua encoder * Handle special-case numbers in Lua encoder * Reject unhandled scalar Tags in Lua encoder * Add note about how Lua nil is unsuitable as table key Could add some context tracking in the future to allow rejecting nil in a table key context. * Return error instead of panic in Lua encoder * Add initial test for Lua encoder Boilerplate mostly copied from toml_test.go * Additional Lua output tests * Generate Lua encoder documentation Mostly just for the boilerplate * Convert octal for Lua output Lua doesn't have the 0oNNN syntax for octal integers, only decimal and hexadecimal, hence those can be passed trough as is while octal needs special treatment. * Implement indentation in in Lua output * Respect string Style in Lua encoder Lua has 'single', "double" and [[ long ]] strings. * Expand Lua examples * Output line comments in Lua output * Implement Lua globals output mode

Fixed in 4.35.1 |

Input support would be cool too. |

Please describe your feature request.
A clear and concise description of what the request is and what it would solve.
Eg. I wish I could use yq to support Lua tables as input and output formats. This would allow querying and manipulating Lua based file formats like LuaRocks rockspec format or the Prosody
internaldata storage format.Describe the solution you'd like
If we have data1.yml like:
(please keep to around 10 lines )
And we run a command:
it could output
or alternatively (perhaps a flag)
Lua tables support arbitrary types as both keys and values, but in stored serialized formats this is rarely used, so keeping to a subset such as only allowing scalar keys may be sensible.
Describe alternatives you've considered
Writing simple converters to/from Lua and yaml/json etc is relatively easy, I have a few of these already, but they lack the query and manipulation capabilities and usually don't preserve comments or order of keys like
yqdoes.The text was updated successfully, but these errors were encountered:
