string.gsub is nice

[numToStr]

Somehow, I forgot about string.gsub which is powerful & useful, and I think using it should reduce the string concatenation mess that I currently have.

local a = '   /*     /*     .class {}           */           */'       
                                                                       
print(vim.inspect({ string.gsub(a, '^(%s*)/%*%s(.-)%s%*/$', '%1%2') }))
                                                                       
local a1 = '    --     local    a   =    123'                          
                                                                       
print(vim.inspect({ string.gsub(a1, '^(%s*)%-%-%s', '%1') }))

print(vim.inspect({ string.gsub(b, '^(%s*)(.*)', '%1/* %2 */') }))

print(vim.inspect({ string.gsub(b1, '^(%s*)', '%1-- ') }))        

local padding = ' '
local min_indent = 4
local b2 = '        local a = 123'

print(vim.inspect({
    string.gsub(
        b2,
        min_indent and string.format('^(%s)', string.rep('%s', min_indent)) or '^(%s*)',
        string.format('%%1--%s', padding)
    ),
}))
     

(I am also not sure whether this will work for all the cases, well I need to explore that too)

Done, wherever necessary.
