Methods

read_gadget2(filename::AbstractString, units, fileunits = uGadget2; kw...)

Return a Tuple of header and particle data in snapshot file. units is supported by PhysicalParticles: uSI, uCGS, uAstro, uGadget2, nothing. fileunits is the internal units in the file, and will be converted to units while reading the file.

Keywords

• acc::Bool = false : read acceleration data if exist
• pot::Bool = false : read potential data if exist

read_gadget2_pos(filename::AbstractString, units, fileunits = uGadget2)

Only read position block and return a StructArray.

writegadget2(filename::AbstractString, header::HeaderGadget2, data::AbstractArray, units = uGadget2; format2 = true, kw...) writegadget2(filename::AbstractString, data, units = uGadget2; kw...)

Write particle data to file. units are supported by PhysicalParticles: uSI, uCGS, uAstro, uGadget2, nothing. Gadget2 header is automatedly generated if not provided.

Keywords

• format2 = true: if true, write in format-2 of Gadget2 snapshot
• acc::Bool = false : write acceleration data
• pot::Bool = false : write potential data

write_gadget2_format2(filename::AbstractString, header::HeaderGadget2, data::AbstractArray, units = uGadget2; kw...)
write_gadget2_format2(filename::AbstractString, data, units = uGadget2; kw...)

Write particle data to format-2 Gadget2 snapshot file. units are supported by PhysicalParticles: uSI, uCGS, uAstro, uGadget2, nothing. Gadget2 header is automatedly generated if not provided.

Keywords

• acc::Bool = false : write acceleration data
• pot::Bool = false : write potential data

function renamesuffixs(folder::AbstractString, namebase::AbstractString, suffix::AbstractString)

Replace the end of all files whose name contain namebase with suffix.

Example

For files test_1.middle.txt and test_2.middle.txt, with command

renamesuffixs("./", "test", ".csv")

we will get test_1.middle.csv and test_2.middle.csv

function renamereplace(folder::AbstractString, old::AbstractString, new::AbstractString; kw...)

Replace string old in all files to new. Keywords kw... are passed to replace
