IGC

A Julia library to interact with IGC file.

Be aware that this library is alpha version (ie it shouldn't be considered as a release version).

IGC file format is defined using Technical Specification for IGC-approved GNSS Flight Recorder from FAI INTERNATIONAL GLIDING COMMISSION

Installation

julia> using Pkg
julia> Pkg.clone("https://github.com/scls19fr/IGC.jl")

Usage

Read an IGC file

julia> using IGC

julia> cd(joinpath(dirname(pathof(IGC)), "..", "test"))

julia> fname = joinpath("data", "example.igc")

julia> igcdoc = read(fname, IGCDocument)

julia> igcdoc.<press_tab>
comment_records       errors                 fix_records            k_records              security_records
dgps_records          event_records          header                 logger_id              stream
eol                   fix_record_extensions  k_record_extensions    satellite_records      task

julia> igcdoc.logger_id
IGC.A_record("XXX", "ABC", "FLIGHT:1")

julia> igcdoc.header
IGC.Header(IGC.H_record_FiXAccuracy('F', 35), IGC.H_record_DaTE('F', 2001-07-16), IGC.H_record_PiLoT('F', "Bloggs Bill D"), IGC.H_record_Copilot('F', "Smith-Barry John A"), IGC.H_record_GliderType('F', "Schleicher ASH-25"), IGC.H_record_GliderRegistration('F', "ABCD-1234"), IGC.H_record_GpsDatum('F', "WGS-1984"), IGC.H_record_FirmwareRevision('F', "6.4"), IGC.H_record_HardwareRevision('F', "3.0"), IGC.H_record_ManufacturerModel('F', "Manufacturer", "Model"), IGC.H_record_GpsReceiver('F', "MarconiCanada", "Superstar", 12, IGC.MaxAlt(10000, "m")), IGC.H_record_PressureAltitudeSensor('F', "Sensyn", "XYZ1111", IGC.MaxAlt(11000, "m")), IGC.H_record_CompetitionId('F', "XYZ-78910"), IGC.H_record_CompetitionClass('F', "15m Motor Glider"))

julia> igcdoc.task.info
IGC.C_record_task_info(IGC.DeclarationInstant(2001-07-15, 21:38:41), 2001-07-16, "0001", 2, "500K Tri")

Write an IGC file using a stream approach

julia> using IGC

IOBuffer(data=UInt8[...], readable=true, writable=true, seekable=true, append=false, size=0, maxsize=Inf, ptr=1, mark=-1)

julia> igcdoc = IGCDocument(stream = io, parsing_mode = ParsingMode.STRICT)

julia> update!(igcdoc, A_record("XXX", "ABC", "FLIGHT:1"))
16

julia> update!(igcdoc, H_record_FiXAccuracy('F', 35))

13

julia> String(take!(io))
"AXXXABC FLIGHT:1\nHFFXA035\nHFDTE160701\nHFPLTPILOTINCHARGE:Bloggs Bill D"
