It seems that there are some problems for (Con)TeX(t) when hyphenating macronized words. When I inspect the ConTeXt language-file for Latin (http://www.pragma-ade.nl/general/manuals/languages-mkiv.pdf), it tells TeX that ē=e, and so on. Here is a MWE with a very small textwidth, so many hyphenations.

Vulpēs, quae per silvam errat et cibum quaerit, eum aspicit. Cāseum quoque videt. Eum ā corvō capere et ipsa ēsse vult. Ergō sē occultat inter folia, quae sunt in iīs rāmīs, quī nōn procul ā terrā absunt. Nam ā corvō vidērī nōn vult.
Vulpēs sē nōn movet, sed tantum verba facit: ''Ō corve, quam fōrmōsa est cauda tua, quam pulchrae sunt ālae! Ostende mihi ālās tuās!'' Corvus, quī ea vērba audit, dēlectātur et sē vertit et circumspicit.

color[red]same text, now without macrons, see the difference:

Vulpes, quae per silvam errat et cibum quaerit, eum aspicit. Caseum quoque videt. Eum a corvo capere et ipsa esse vult. Ergo se occultat inter folia, quae sunt in iis ramis, qui non procul a terra absunt. Nam a corvo videri non vult.
Vulpes se non movet, sed tantum verba facit: ''O corve, quam formosa est cauda tua, quam pulchrae sunt alae! Ostende mihi alas tuas!'' Corvus, qui ea verba audit, delectatur et se vertit et circumspicit.

Why does the hyphenation before or after a macronized vowel not happen?

Better MWE:

If you want the macrons to be recognized, you have to add them to the characters list in the pattern. Here is a hackish way to do it:

1. Find the file lang-la.lua in your distribution.


2. Copy the file in your working directory


3. Find the line ["characters"]="abcdefghijklmnopqrstuvxzæœ", and add āēī to the string → ["characters"]="abcdefghijklmnopqrstuvxzæœāēī",

Now Henri's example should produce the desired output:

Here is the modified lang-la.lua:

% ==========================================
% Patterns for the latin language mainly in modern spelling
% (u when u is needed and v when v is needed); medieval spelling
% with the ligatures \ae and \oe and the (uncial) lowercase `v'
% written as a `u' is also supported; apparently there is no conflict
% between the patterns of modern Latin and those of medieval Latin.
%
% For more information please read the babel-latin documentation.

% For documentation see:
% C. Beccari, "Computer aided hyphenation for Italian and Modern
% Latin", TUG vol. 13, n. 1, pp. 23-33 (1992)
%
% see also
%
% C. Beccari, "Typesetting of ancient languages",
% TUG vol.15, n.1, pp. 9-16 (1994)
%
% In the former paper the code was described as being contained in file
% ITALAT.TEX; this is substantially the same code, but the file has been
% renamed and included in hyph-utf8.
%
% A corresponding file (ITHYPH.TEX) has been extracted in order to eliminate
% the (few) patterns specific to Latin and leave those specific to Italian;
% ITHYPH.TEX has been further extended with many new patterns in order to
% cope with the many neologisms and technical terms with foreign roots.
%
% Should you find any word that gets hyphenated in a wrong way, please, AFTER
% CHECKING ON A RELIABLE MODERN DICTIONARY, report to the author, preferably
% by e-mail. Please do not report about wrong break points concerning
% prefixes and/or suffixes; see at the bottom of this file.
%
% Compared with the previous versions, this file has been extended so as to
% cope also with the medieval Latin spelling, where the letter `V' played the
% roles of both `U' and `V', as in the Roman times, save that the Romans used
% only capitals. In the middle ages the availability of soft writing supports
% and the necessity of copying books with a reasonable speed, several scripts
% evolved in (practically) all of which there was a lower case alphabet
% different from the upper case one, and where the lower case `v' had the
% rounded shape of our modern lower case `u', and where the Latin diphthongs
% `AE' and `OE', both in upper and lower case, where written as ligatures,
% not to mention the habit of substituting them with their sound, that is a
% simple `E'.
%
% According to Leon Battista Alberti, who in 1466 wrote a book on
% cryptography where he thoroughly analyzed the hyphenation of the Latin
% language of his (still medieval) times, the differences from the Tuscan
% language (the Italian language, as it was named at his time) were very
% limited, in particular for what concerns the handling of the ascending and
% descending diphthongs; in Central and Northern Europe, and later on in
% North America, the Scholars perceived the above diphthongs as made of two
% distinct vowels; the hyphenation of medieval Latin, therefore, was quite
% different in the northern countries compared to the southern ones, at least
% for what concerns these diphthongs. If you need hyphenation patterns for
% medieval Latin that suite you better according to the habits of Northern
% Europe you should resort to the hyphenation patterns prepared by Yannis
% Haralambous (TUGboat, vol.13 n.4 (1992)).
%
%
%
% PREFIXES AND SUFFIXES
%
% For what concerns prefixes and suffixes, the latter are generally separated
% according to "natural" syllabification, while the former are generally
% divided etimologically. In order to avoid an excessive number of patterns,
% care has been paid to some prefixes, especially "ex", "trans", "circum",
% "prae", but this set of patterns is NOT capable of separating the prefixes
% in all circumstances.
%
% BABEL SHORTCUTS AND FACILITIES
%
% Read the documentation coming with the discription of the Latin language
% interface of Babel in order to see the shortcuts and the facilities
% introduced in order to facilitate the insertion of "compound word marks"
% which are very useful for inserting etymological break points.
%
% Happy Latin and multilingual typesetting!
