Support for multi file documents

[danbim]

I'm editing a larger document that is spread throughout multiple .tex files, e.g.,

main.tex
part_a.tex
...
part_z.tex

and main.tex includes part_a.tex to part_z.tex via \input and also includes the .bib file. Latexer does not find any citations when I'm working inside one of part_a.tex to part_z.tex.

Spontaneous ideas to overcome this situation:

• allow to set path to bibfile(s) in configuration of latexer
• scan all .tex files in dir for bibfile(s)
• use % !TEX directives (see e.g., http://tex.stackexchange.com/questions/78101/when-and-why-should-i-use-tex-ts-program-and-tex-encoding). this way you could scan the current file to find the root file, that in turn includes all files to scan for bibtex files included.
• allow to disable bibfile autocompletion in the latexer configuration. there's a plugin (https://atom.io/packages/autocomplete-bibtex) specialized on bibtex-autocompletion that is obviously conflicting with latexer autocompletion features.

Also a good idea could be to separate the three different autocompletion features (reference, bibliography and environment) of latexer in individual plugins so people can choose freely between plugins that partially overlap in functionality (see last point in the list above).

I had the same issue; as a very ugly hack I edited ~/.atom/packages/latexer/lib/cite-view.coffee and changed the following block:

  getCitations: ->
    cites = []
    bibRex = /\\bibliography{([^}]+)}/g
    while (match = bibRex.exec(@editor.getText()))
      if not /\.bib$/.test(match[1])
        match[1] += ".bib"
        path = FindLabels.getAbsolutePath(@editor.getPath(), match[1])
        cites = cites.concat(@getCitationsFromPath(path))
    cites

Removing the while-loop and replacing “match[1]” with the path to the .bib-file does the trick. The result looks as follows:

  getCitations: ->
    cites = []
    path = FindLabels.getAbsolutePath(@editor.getPath(), "[path-to-bibfile]")
    cites = cites.concat(@getCitationsFromPath(path))
    cites

It does seem to work, but this is obviously not a permanent solution.

Hi. This issue is resolved with balu's fix. The program now will look for a %!TEX root = root.tex inside of the file.
